Embodiment Construction

[0067] refer to figure 1 , Embodiments of the present invention are constructed in the drive train of a single-deck passenger vehicle. drive system in figure 1 is shown with the rear of the vehicle towards the top of the figure, and with the vehicle's front-rear axis extending vertically with respect to the figure.

[0068] The drive train includes an internal combustion engine 10 mounted longitudinally at the rear of the vehicle. The output shaft extends in a forward direction to connect to the multi-speed vehicle transmission 12 through a coupling such as a torque converter or a clutch. The output from the vehicle transmission 12 passes through the layshaft 34 (only on image 3 and Figure 4 shown in ) to the transfer case 14. From the transfer case 14 , the transmission passes through the propeller shaft 16 to the final drive unit 18 housed in the live axle 20 . Inside the axle 20 the transmission is transmitted from the final drive unit to the driven road wheels 22 v...

Abstract

A drive train for a vehicle and a method of operating a vehicle are disclosed. The drive train comprises a transmission system that includes a vehicle transmission (12) and a final drive unit (18). The drive train additionally has a kinetic energy recovery system that includes an energy storage means (30) which typically includes a flywheel. The kinetic energy recovery system is operatively coupled, to be driven by and to drive, the transmission system between the vehicle transmission and the final drive unit (18). Components of the kinetic energy recovery system may be contained in a transfer box (14) connected to an output of the vehicle transmission (12). A propshaft (16) may connect the transfer box (14) to the final drive (18). Further claims relate to a method of operation and a method of retrofitting the drive train, by mounting an engine (10) further spaced from the final drive unit (18).

Description

technical field [0001] The invention relates to a drive train for a vehicle. More particularly, the present invention relates to drive trains that provide kinetic energy recovery during operation of a motor vehicle, such as an on-highway motor vehicle powered by a combustion engine. It finds particular, but not exclusive application in transmission systems of passenger vehicles. Background technique [0002] In this specification, terms such as upper, lower, transverse and related terms should be understood as referring to the power train and its components in their normal configuration when installed in the vehicle, and front and rear, and related terms refer to the vehicle in its direction of travel during normal operation. [0003] In the operation of a conventional vehicle powered by a combustion engine, the kinetic energy of the vehicle in motion is lost as the vehicle decelerates by being converted to heat in the vehicle's braking system or by inhibiting / damping its ...
