The AEC Regent III was a postwar Bus built in Britain during the 1940s to the late 1950s.

History

The Regent III first made its appearance in 1947, being a double-deck chassis with 16ft 4in wheelbase built in both 7ft 6in and 8ft widths. The war had eventually came to an end, and the roads of Great Britain required new vehicles, and in 1948 the time came for expansion resulting in two famous vehicle manufacturers, Crossley Motors Limited, and The Maudslay Motor Company becoming associated with the A.E.C. Ltd., eventually merging,also with bodybuilders Park Royal Vehicles Ltd and Charles H Roe Ltd.

Following this merger the parent company had a change of name, Associated Commercial Vehicles Limited. The initials AEC.

The First of the new line full cab were still to remain in a new company AEC Limited formed to assume all design, engineering, production, and marketing responsibilities of the old company. In 1949 the company gained further strength with the addition of Park Royal Vehicles Limited, with its associate Chas. H. Roe of Leeds providing a body building service. while Park Royal was to work closely with AEG Ltd in the manufacture of chassis passenger models. At about this time, vehicles exported to Spain.
The early 1950s demanded new designs of commercial vehicles to cater for new regulations, higher cost of operation. Powered by a 6-cylinder 9.6 litre AEC oil engine, it was offered as the 0961/2 model with fluid flywheel, 4-speed pre-selector gearbox and air brakes, or as the 0961/2 to SV179 model with 4-speed sliding mesh gearbox and vacuum servo brakes.

Also introduced in 1947 was a 7.7 litre engined model of the Regent III classified 0681. This had a 4-speed sliding mesh gearbox and vacuum servo brakes, and was reclassified 6811A in 1948.

In 1948 these two models were reclassified 9612E and 9612A respectively.

Two years later, in 1950 the Regent III was lengthened to accommodate 27ft longbodywork. Although the wheelbase remained at 16ft 4in. Thus in this longer form the 9612E, 9612A, and 681 IA models were re-classified 9613E, 9613A and 6812A.

In 1952 a new 4-speed synchromesh gearbox was introduced as a replacement for the sliding mesh unit and chassis fitted with this were given an 'S' suffix, the 9613A becoming 9613S and the 6812A becoming 6812S.

although during the final two years few were built due to the appearance of the Regent V in 1954,there was still over 5,930 Regent III chassis built before production ended in 1957.

AEC Regal III Bus

Manufacturer	AEC
Production	1947 to 1957
Class	Commercial vehicle
Body style	bus single-deck
Engine	7.7 or 9.6 litre 6-cylinder diesel
Transmission	4-speed
Wheelbase	17ft 6in and 19ft 3in
Length	26-30ft

The AEC Regal III was a British Bus first built in the 1940s after the 2nd world war and was built for 10 years.

History

Introduced in 1947, the Regal III is a single-deck version of the 'Provincial' Regent III double-decker bus and is known as the 0962 model.

With a 17ft 6in wheelbase it is fitted with an AEC 9.6 litre 6-cylinder oil engine, fluid flywheel 4-speed pre-selective gearbox and air brakes, In 1948 a sliding mesh 4-speed gearbox and friction clutch was offered as an alternative to the fluid flywheel, and some months later an optional engine, the AEC 7.7 litre unit was offered.

From 1948 both 7ft 6in and 8ft wide models were available, and in 1950 a longer wheelbase chassis of 19ft 3in was produced to carry 30ft long bodywork. This had, however, been produced since 1948 for the export market, and therefore was not an entirely new dimension.

At this time the chassis classification was altered to give now four different versions, these being.

• 9621 E — 9.6 litre engine with pre-selective gearbox
• 9621 A — 9.6 litre engine and sliding mesh gearbox
• 6821 E — 7.7 litre engine with pre-selective gearbox
• 6821 A — 7.7 litre engine and sliding mesh gearbox

When production ended in 1957, over 2,150 Regal IIIs had been built for the home market.

AEC Mammoth Lorry history

Manufacturer:	Associated Equipment Company
Production period:	1930 to 1978
Type	commercial vehicle
Body	Truck various
Engines:	diesel engines

The AEC Mammoth was a heavy truck produced by the British manufacturer Associated Equipment Company (AEC) from 1930 to 1978 in various designs. A distinction is in principle made between the three-axle AEC Mammoth Minor with the wheel formula 6 × 2, the three-axle AEC Mammoth Major 6 with the wheel formula 6 × 4 and the four-axle AEC Mammoth Major 8 with the wheel formula 8 × 4 × 4.

History 

1930s

The first AEC Mammoth , still without the addition Minor , appeared in 1930 with the type designation 667 . The Mammoth Major followed in 1931 with the type designation 668 . The trucks were as axle vehicles with forward-control - cab designed. The Mammoth Major was built under the type designation 266 / O266 as Langhauber. With a wheelbase of 16  feet and 7 inches, they had a gross mass of about 7-8 tons. The vehicles were powered by a six-cylinder engine with a power of 110  bhp . 

1934 followed the four-axle AEC Mammoth Major 8 , which could carry a payload of 15 tons. Neither the condition of the roads at the time nor existing technologies allowed for high axle loads . The only way to increase the payload was therefore to increase the number of axles. The concept of the four-axle truck was first introduced in 1929 in steam-powered vehicles. The Mammoth and the AEC Mammoth Major 8 remained in production until 1935, the Mammoth Major until 1939.

1940s 1950s

The first generation was replaced by the series 366 (three-axle) and 386 (four-axle) from 1935, which were produced until 1948. This also designated as Mk II series was replaced in 1948 by the Mk III. Constructively similar design, the new vehicles now had a front handlebar assembly by Park Royal . After the takeover of the competitor Maudslay in 1948 AEC offered the Mammoth for a while under this name. At the Commercial Motor Show in 1958, AEC introduced Mk V before  The Mk V differed from its predecessors by a new cab, new engines, recessed front axles, an improved brake system and a new rear axle construction. The older Mk III was manufactured 18 months in parallel with the new version before its production was finally discontinued. One of the four-axle's largest customers was British Road Services . Mk V built more than 6000 pieces.

1960s

1965 appeared the last series of Mammoth with a new cab. This cab called ergomatic cab , also available for other trucks , had already been introduced by AEC at the 1964 London Motor Show . For the first time also a three-axle with two steerable front axles was offered.

TG6RB, TG6RBE, TG6LB and TG8RB:Double drive, double reduction spiral bevel axles and lockable inter-axle differential, fully articulated suspension, with worm and nut steering on TG6RB, TG6RBE, TG6LB and cam and roller steering on TG8RB.

TG6RNE:Double drive, single reduction spiral bevel axles, with lockable inter-axle differential and power divider on leading axle, four spring rear suspension and worm and nut steering.
TG8RT:Double drive, double reduction spiral bevel axles and lockable inter-axle differential, four spring rear suspension, and cam and roller steering.

TG8RD and TG6LD:Double drive, overhead worm reduction axles, four spring rear suspension, with cam and roller steering on TG8RD, and worm and nut steering on TG6LD.

TG8RS and TG6LS:Single drive, double reduction spiral bevel axle with four spring rear suspension, non-driving trailing rear axle, with cam and roller steering on TG8RS and worm and nut steering on TG6LS.

TG6RT:Double drive, double reduction spiral bevel axles and lockable inter-axle differential, four spring rear suspension, and worm and nut steering.
TG6RF:Single drive, double reduction spiral bevel axle with two spring rear suspension, twin steering front axles, and cam and roller steering.
TG6RB and TG6RBE:Double drive double reduction spiral bevel axles, fully articulated suspension, and worm and nut steering.

The vehicles were equipped during the long production time with various four, six and eight-cylinder diesel engines from AEC , Leyland Motors and Gardner . Various manual, four-, five- and six-speed transmissions with and without overdrive were used. Older vehicles have often been remotorized, often with non-type components installed to better adapt the vehicles to the needs of their owners. In addition to the widespread cabs, the chassis was also offered as Langhauber. In addition to flatbed trucks were mainly tankers and dump trucks widespread.

1970s

The 24 ton Marshal, in either 6x2 or 6x4 form, has the work- proven and reliable 151 b.h.p.gross AV505 diesel which provides a very high torque output.Transmission is through a six- speed overdrive gearbox driving through robust single-reduction spiral bevel rear axles with differential lock in the leading axle to give good traction under the worst conditions.
The 28/30 ton Mammoth Major for tipper or haulage use is available in 8x2 and 8x4 forms. Both versions give power to spare with the 212 b,h.p. gross AV760 diesel, with a smooth transmission through a robust clutch and a six-speed overdrive or alternative 10-speed overdrive
gearbox. The drive axles are two heavy duty single reduction units on haulage models and heavy duty double reduction units on tipper chassis.
A lockable third differential is standard on the 8x4 models and a double-reduction unit with optional cross-lock differential and trailing axle in the version. Whichever vehicle you
operate traction and adequate speed,allied to first class reliability and economy are the benefits of these carefully designed drive trains.

The AEC Regent MkV was introduced in 1954, and during its years of production a number of variations have been available, Originally designed as a 27ft long model, it had a wheelbase of 16ft 4in, a 30ft long version with 18ft 7in wheelbase being introduced in 1956.

Engines

Although generally built with a wide bonnet of the so called 'new look' style, exposed radiators were available as an option until 1960. Two different engines were offered, one being an AEC 9.64 litre 6-cylinder oil engine whilst the other was a new AEC 7.685 litre 6-cylinder unit given model number A470.

Transmission

A choice of transmission was also given with either a single plate clutch and 4-speed synchromesh gearbox or fluid flywheel and 4-speed electro-pneumatic direct acting epicyclic gearbox. Further alternatives involved the braking system which could be air pressure operated or of the triple vacuum servo type.

All chassis were offered as 8ft wide, although 7ft 6in models were available to meet customers special requirements. The Regent V continued in production until 1969.
