Problems solved by technology

Additionally, mounting the motor generator to the axles adds to the vehicle's unsprung weight, which is undesirable for passenger comfort and vehicle handling, and undesirably makes the motor generator wobble
Unsprung weight is also uneven, which can lead to different handling for both sides of the vehicle

Embodiment Construction

[0061] Such as Figure 5 As shown, a vehicle 5 in the form of a double decker bus has wheels 90, brakes 11, an engine 10 and a hybrid powertrain motor generator 140, wherein the hybrid powertrain motor generator 140 communicates with a mechanical flywheel (or mechanical energy storage components) unit 7 , the vehicle battery or chemical / electrical energy storage 15 and the control system 13 . The motor-generator can send electrical energy to and receive energy from the mechanical flywheel unit 7 . The mechanical flywheel unit 7 may comprise means (not shown) with a further motor-generator for converting electrical energy into mechanical energy by rotating the mechanical flywheel upwards, and subsequently converting the mechanical energy into electrical energy to provide electric power to the motor generator 140 . The motor-generator 140 may comprise a single alternator unit in which the same coils are used for both motoring and generating modes; or the motor-generator 140 ma...

Abstract

The invention relates to a hybrid powertrain kit for converting a non-hybrid bus vehicle to a bus with a hybrid powertrain, the hybrid powertrain comprising thus a hybrid system having a drive system for drivingly communicating energy passing between a final drive of such vehicle and an energy store, the hybrid system being mountable behind the rear wheel between the rear wheel and the engine and / or gearbox.

Description

technical field [0001] The present invention relates to hybrid powertrain systems for hybrid vehicles such as heavy-duty buses, particularly vehicles of the type capable of storing kinetic energy, and to hybrid powertrain systems and kits for converting non-hybrid vehicles into said hybrid vehicles and method. Background technique [0002] Some public buses (buses) and public service vehicles (PSVs) are configured to maximize passenger space and ensure access to the powertrain for maintenance. For example DE2934314A discloses an arrangement in which an internal combustion (IC) engine is positioned suspended over the rear axle and transverse to the vehicle centreline. Angle drives are used to obtain output drive from the engine in the forward direction through propellers or drive shafts for driven shafts. [0003] This layout has become almost standard for current bus or PSV designs. GB2117335A shows the figure 2 similar arrangement, in figure 2 , the sharp angle towards...
