“Leyland Motors”的意思、由来-开放百科全书

Leyland Motors Limited (later known as the Leyland Motor Corporation) was a British vehicle manufacturer of lorries, buses and trolleybuses. The company diversified into car manufacturing with its acquisitions of Triumph and Rover in 1960 and 1967, respectively. It gave its name to the British Leyland Motor Corporation, formed when it merged with British Motor Holdings in 1968, to become British Leyland after being nationalised. British Leyland later changed its name to simply BL, then in 1986 to Rover Group.

Although the various car manufacturing businesses were eventually divested or went defunct due to the troubled existence of BL and its successors (Mini and Jaguar Land Rover are the two surviving organisations), the original Leyland Trucks business still exists as a subsidiary of Paccar.

History

Beginning

Leyland Motors has a long history dating from 1896, when the Sumner and Spurrier families founded the Lancashire Steam Motor Company in the town of Leyland in North West England. Their first products included steam lawn mowers.^[1] The company's first vehicle was a 1.5-ton-capacity steam powered van. This was followed by a number of undertype steam wagons using a vertical fire-tube boiler.^[2] By 1905 they had also begun to build petrol-engined wagons. The Lancashire Steam Motor Company was renamed Leyland Motors in 1907 when it took over Coulthards of Preston, who had been making steam wagons since 1897.^[3] They also built a second factory in the neighbouring town of Chorley which still remains today as the headquarters of the Lex Autolease and parts company.

In 1920, Leyland Motors produced the Leyland Eight luxury touring car, a development of which was driven by J.G. Parry-Thomas at Brooklands. Parry-Thomas was later killed in an attempt on the land speed record when the car overturned. Rumours that a chain drive broke were found to be incorrect when the car was disinterred late in the 20th century as the chains were intact.. At the other extreme, they also produced the Trojan Utility Car in the Kingston upon Thames factory at Ham from 1922 to 1928.

Three generations of Spurriers controlled Leyland Motors from its foundation until the retirement of Henry Spurrier in 1964. Spurrier inherited control of Leyland Motors from his father in 1942, and successfully guided its growth during the postwar years. Whilst the Spurrier family were in control the company enjoyed excellent labour relations—reputedly never losing a day's production through industrial action.

World War II

During World War II, Leyland Motors, along with most vehicle manufacturers, was involved in war production. Leyland built the Cromwell tank at its works from 1943 as well as medium/large trucks such as the Hippo and Retriever.

After the war, Leyland Motors continued military manufacture with the Centurion tank.

Post war

In 1946, AEC and Leyland Motors form British United Traction. to build trolleybuses

In 1955, through an equity agreement, manufacture of commercial vehicles under licence from Leyland Motors commenced in Madras, India at the new Ashok factory. The products were branded as Ashok Leyland.

On the other hand, Leyland Motors acquired other companies in the post war years:

Holding company: Leyland Motor Corporation

Donald Stokes, previously Sales Director, was appointed managing director of Leyland Motors Limited in September 1962^[5] originally a Leyland student apprentice he had grown up with the company.^[7] He became chairman in 1966. In 1968 Leyland Motors merged with British Motor Holdings (BMH) to form the British Leyland Motor Corporation (BLMC). BMH, which was the product of an earlier merger between the British Motor Corporation, the Pressed Steel Company and Jaguar, brought with it into the new organisation more famous British goods vehicle and bus and coach marques, including Daimler, Guy, BMC, Austin and Morris.

Leyland diesel engines were used in Finnish Sisu and Vanaja lorries and buses in 1960s.

British Leyland era

The BLMC group was difficult to manage because of the many companies under its control, often making similar products. This, and other reasons, led to financial difficulties and in December 1974 British Leyland had to receive a guarantee from the British government.

In 1975, after the publication of the Ryder Report and the company's bankruptcy,^[8] BLMC was nationalised as British Leyland (BL) and split into four divisions with the bus and truck production becoming the Leyland Truck & Bus division within the Land Rover Leyland Group. This division was split into Leyland Bus and Leyland Trucks in 1981. Leyland Trucks depended on British sales as well as export markets, mainly commonwealth and ex-Commonwealth markets. The early 1980s were very hard, with export sales drying up in many places such as oil-dependent Nigeria.^[9] In 1986, BL changed its name to Rover Group. The equity stake in Ashok Leyland was controlled by Land Rover Leyland International Holdings, and sold in 1987. At this point, while building about 10,000 trucks per annum, Leyland was more and more depending on outside engines as production of their own 98-series was steadily declining. The 1986 closure of Bedford's heavy truck plant further harmed Leyland, as they had been planning on selling axles and other components to the General Motors subsidiary.^[10]

Buses

The bus operations was sold in a management buyout to form Leyland Bus, and was subsequently bought by Volvo Buses in 1988, which discontinued most of its product range but adopted the Leyland Olympian, re-engineering it as the first named Volvo Bus model, the Volvo Olympian aside from minor frame changes the major alterations were the fitment of Volvo axles, braking system and controls. Both were the best selling double-deck bus chassis of their time.

Ashok Leyland

The Leyland name and logo continues as a recognised and respected marque across India, the wider subcontinent and parts of Africa in the form of Ashok Leyland. Part of the giant Hinduja Group, Ashok Leyland manufactures buses, trucks, defence vehicles and engines. The company is a leader in the heavy transportation sector within India and has an aggressive expansionary policy. Ironically, since 1987, when the London based Hinduja Group bought the Indian-based Ashok Leyland company. Today, Ashok-Leyland is pursuing a joint venture with Nissan, and through its acquisition of the Czech truck maker, Avia, is entering the European truck market directly. With its purchase of a 26% stake in UK-based bus manufacturer Optare in 2010, Ashok Leyland has taken a step closer to reconnecting with its British heritage, as Optare is a direct descendant of Leyland's UK bus-making division. On 21 December 2011, Ashok Leyland bought an additional 49% stake in Optare, bringing its total to 75%.

Buses

Historically, Leyland Motors was a major manufacturer of buses used in the United Kingdom and worldwide. It achieved a number of firsts or milestones that set trends for the bus industry. It was one of the first manufacturers to devise chassis designs for buses that were different from trucks, with a lower chassis level to help passengers to board. Its chief designer, John George Rackham, who had experience at the Yellow Coach Company in Chicago before returning to England,^[11] created the Titan and Tiger ranges in 1927 that revolutionised bus design. After 1945, it created another milestone with the trend-setting Atlantean rear-engined double-decker bus design produced between 1956 and 1986.

The G-series cab was built in Bathgate and was available with several different names, such as Terrier, Clydesdale, and Reiver. After this cab was replaced the tooling was shipped to Turkey, where BMC's Turkish subsidiary built it as the "BMC Yavuz" and then as the "Fatih" (with Cummins engines) from 1986 until 1996.

The Marathon was Leyland's answer to the booming "max cap" truck fad at the start of the 1970s. Imports such as the Volvo F88 and Scania 110/140 were selling very well in the UK thanks to the previously unheard of levels of driver comfort, reliability, quality and performance.

Leyland had insufficient money for development of a complete new vehicle at the time, so designers were instructed to utilise as many existing in-house components as possible. It was perceived at the time that the resulting model would be a stopgap until the new T45 range was ready for production toward the latter half of the 1970s.

The cab was a re-worked version of the "Ergomatic" tilt cab of 1965, heavily modified with different lower panels, raised height etc., and was available in day and sleeper cab form. Engines were decided from the outset to be in the higher power category to be competitive with rival vehicles. The only existing engine within the Leyland empire suitable for such an application (following the demise of the ill-fated fixed-head 500 series and AEC's underdeveloped and unreliable V8) was the AEC AV760 straight-six, which was turbocharged and designated as the TL12. Other engine options included a 200 bhp Leyland L11, as well as Cummins 10- and 14-litre engines at 250 and 330 bhp, respectively.

Production began in 1973, and various shortcomings were noted, including below-par heating and ventilation, and pronounced cab roll. However, road testers of the time were very impressed by the truck's power and performance. In 1977, the redesigned "Marathon 2" was launched, an updated and revised vehicle that attempted to address some of the previous criticisms of the earlier vehicle. Relatively few Marathons of all types were sold before production ended in 1979 with the introduction of the T45 "roadtrain" range of vehicles.

1980s

This was Leyland's answer to the Ford cargo in the non-HGV 7.5-ton truck sector. Launched in 1984, it utilised a Leyland 698 straight-six engine until 1986, when a 5.9 L Cummins was introduced. It was notable at the time for its low-level passenger side windscreen, featured as a safety aid to enable the driver to see the kerb, although this was deleted on later models. The basic cab had a long service life, becoming later on the Leyland DAF 45.

The Leyland Constructor was a 6x4, three axle wagon with gross weight up to 24 tonnes used as a tipper or on short haul distribution duties.

The Leyland Roadtrain was a range of heavy goods vehicle tractor units manufactured by Leyland Trucks between 1980 and 1990. The nomenclature "T45" refers to the truck range as a whole and encompasses models such as the lightweight 7.5-ton Roadrunner, Freighter (fourwheel rigid truck), Constructor (multi-axle rigid tipper or mixer chassis – its chassis owing much to the outgoing Scammell 8-wheeler Routeman^[13]), and Cruiser (basic spec low weight tractor unit). The Roadtrain itself was a max weight model with distance work in mind.

The T45's cab is called the C40 and its design was a joint effort between Leyland, BRS and Ogle Design and was seen as the height of modernity when compared with its predecessors, the idea being to have one basic design to replace the various outgoing models (for example, the Bathgate built G cab on the Terrier, the Ergomatic cabbed Lynx, Beaver etc.). This did indeed make good economic sense; however, there has been speculation that Leyland did in fact alienate a number of customers who had traditionally purchased other marques from within the Leyland empire—Albion, AEC, Scammell, etcetera – who were now left with no alternative but to have a Leyland-branded vehicle or purchase from elsewhere. Some Constructors, with their Scammell-based chassis, were built with Scammell badging as well.

Throughout its production run, engine choices included the AEC-based TL12, a straight carry over from the preceding "stopgap" model Marathon range, The Rolls-Royce Eagle 265/300 and the Cummins 290 L10 and 14-litre 350 coupled to a Spicer or Eaton transmission, although all versions produced a distinctive whine from the propshaft knuckle joint when approaching {{convert|60|mi/h|km/h|abbr=on}}. The TL12 engine was dropped early on in the production run, with most large fleet buyers choosing the Rolls-Royce engine.

The Roadtrain was available in day- and sleeper-cabbed form, in high and low datum versions—this refers to the cab height—high datum versions were intended as long haul vehicles with higher mounted cabs and more internal space. 6x2 versions were built in high cab form only on a chassis that was basically that of the ageing Scammell trunker. The Constructor's chassis was entirely Routeman behind the cab, albeit with altered suspension and with the front chassis rails splayed wider apart to fit the new C40 cab.^[13]

In 1986, the high roofed Roadtrain interstate was introduced, a top of the range long distance truck with standing room inside.

The Roadtrain was a common sight throughout most of the 1980s, with a great many of the major fleet users in the UK such as Tesco, Blue Circle Industries (unusually with high datum day cabs) and BRS running them. The firm of Swain's based in Rochester, Kent had a number of roadtrains in its fleet which enjoyed a comparatively long service life (until the late 1990s) before being replaced by the newer DAF 85. Sales were never quite satisfactory, however, with the vacation closure extended in 1986 to reduce unsold stock.^[10]

Production ended in 1990 with the sale of Leyland Trucks to Dutch firm DAF, although as a postscript DAF relaunched the model in low-datum form (it was already manufacturing the large DAF 95) as the DAF 80, using the Roadtrain cab with the {{convert|11.6|L|cuin|adj=on}} DAF 330 ATi engine (quite ironic, given that this engine had its roots in the Leyland O.680^[14]). This model was produced for a relatively short time until 1993 with the launch of the brand new cabbed DAF 85.

Due partly to the cab's propensity to rust and also to the admittedly short life of commercial vehicles, any Roadtrain in commercial operation is now a very rare sight indeed. However, a small number remain in use throughout the country as towing-and-recovery vehicles.

The army made use of an 8x6 version of the Roadtrain as a hook loader until recently. This is known to the British Army as Demountable Rack Offload and Pickup System (DROPS), which has seen action Iraq and Afghanistan and is still in service, but is due to be replaced by the MAN version.

The Leyland Comet was introduced in 1986, specifically designed for export markets mainly in the developing world. As such, it was a no-frills vehicle of a simple and sturdy design, with five- or six-speed transmissions rather than the multi-speed units used on European models. The cabin was a simplified all-steel version of that used by the Roadrunner, designed to enable local assembly. The three-axle version is called the Super Comet.^[15]
