![]() Applications Early uses Įarly transmissions included the right-angle drives and other gearing in windmills, horse-powered devices, and steam-powered devices. Modern versions of these systems that are fully automatic in operation, such as Selespeed and Easytronic, can control both the clutch operation and the gear shifts automatically, without any input from the driver. Some of these systems are also referred to as clutchless manual systems. Many early versions of these transmissions were semi-automatic in operation, such as Autostick, which automatically control only the clutch, but still require the driver's input to initiate gear changes. ![]() Main articles: Automated manual transmission and Clutchless manual transmissionĪn automated manual transmission (AMT) is essentially a conventional manual transmission that uses automatic actuation to operate the clutch and/or shift between gears. In the case of a wind turbine, the first stage of the gearbox is usually a planetary gear, to minimize the size while withstanding the high torque inputs from the turbine. Examples of such transmissions are used in helicopters, wind turbines and power take-offs (PTOs) for tractors. The simplest transmissions used a fixed ratio to provide either a gear reduction or increase in speed, sometimes in conjunction with a change in the orientation of the output shaft. Electric vehicles typically use a single-speed or two-speed transmission.įixed-ratio transmissions Transmission for a Bristol Sycamore helicopter Most currently-produced passenger cars with petrol or diesel engines use transmissions with 5-8 forward gear ratios and one reverse gear ratio. Many transmissions have multiple gear ratios, but there are also transmissions that use a single fixed gear ratio.

Optional engine packages include input shaft & retainer, and bellhousing / adapter plate where applicable. Digital gear position indicator available.Optional heavy duty tailcase with drive flange for higher power applications.Direct drive, overdrive or double overdrive.Optional gear lever positions to suit individual vehicle applications.Adaptor kits available for many other vehicles, please call.Optional engine packages include Mazda MX-5 ND/NB/NC, Nissan SR20, Subaru/Toyota BRZ/GT86, Honda S2000 F20C, BMW E36 M3 S50, BMW E46 S54, Nissan 350 HE/DE.Direct replacement for Ford Type-9 gearbox.Key features of the QBE60G six-speed sequential gearbox include:. More information on our sequential gearboxes can be found here. Weighing just 38 kilos, QBE60G is ideal for rally and race use in Mk1 and Mk2 Ford Escort, Ford Sierra, Caterham, Westfield and numerous rear wheel drive kit cars. This produces a fast, positive gearchange – an optional paddle shift actuator is also available.įree running gears are supported by needle roller bearings, while a choice of ratios and numerous gear lever position options allows customers a wide scope for optimising QBE60G to suit their individual requirements. QBE60G features a modular gear cluster, allowing easier interchangeability of gear ratios, and fewer moving parts, while a drum type sequential gearchange system is allied to an open face dog design on both gear and drive disc. The Quaife QBE60G heavy duty In-line 6-speed RWD Sequential Gearbox is a direct replacement for the popular Ford Type 9 transmission and since its launch in 2008 has become the market leader in this sector.Ī 80mm shaft centre design with all alloy casings enables QBE60G to handle up to 500bhp, yet it can be installed into a Mk1 / Mk2 Ford Escort orĬaterham 7 without transmission tunnel modifications.
