Embodiment Construction

[0028] Referring to the accompanying drawings, the present invention will be further described.

[0029] Such as figure 1 with figure 2 As shown, the present invention provides a hybrid electric vehicle drive system using synchronous belt transmission, that is, the front wheels are powered by the engine, and each rear wheel is powered by a set of wheel-side electric drive system. The specific transmission scheme is: it is composed of a front-wheel engine drive system and two sets of independently controlled rear-wheel electric drive systems, wherein the front-wheel drive system includes an engine 2, a clutch 3, a transmission 9 and a final drive 10, and the power of the engine 2 is passed through The clutch 3, the speed changer 9, and the final drive 10 transmit and drive the front wheels.

[0030] The rear wheel electric drive system includes a power battery 8, two wheel side motors 7 and two sets of synchronous belt reduction mechanisms. The power battery 8 supplies power...

Abstract

The invention discloses a hybrid power electric automobile driving system by utilizing synchronous belt transmission. The driving system is composed of a front wheel motor driving system and two groups of rear wheel electrically driving systems controlled independently; and wheel-side output torque is transmitted to semi-shafts and hubs through synchronous belt small belt wheels, synchronous wheels and synchronous belt large belt wheels to drive rear wheels; and a motor and wheel-side motors do not have direct mechanical contact and change automobile driving modes through a total automobile controller. The hybrid power electric automobile driving system by utilizing synchronous belt transmission has the advantages that the distributed arranging mode is more flexible compared with the integrated motor arranging mode, interior space is saved, multiple kinds of driving control modes of all wheel driving, front wheel driving, rear wheel driving and the like can be achieved, the whole automobile performance is better, reduction of unsprung mass of automobiles is facilitated, the cost is low, and the performance is high.

Description

technical field [0001] The invention relates to a driving system of a hybrid electric vehicle, in particular to a driving system of a hybrid electric vehicle which is arranged in a distributed manner and adopts a synchronous belt to transmit power. Background technique [0002] Modern gasoline-electric hybrid electric vehicles are generally divided into three types: series, parallel and hybrid. Without exception, they all adopt a centralized motor drive scheme, that is, there is a high-power main drive motor and the power of the engine is coupled through the power coupling device and then transmitted to the wheels through the transmission shaft and the final reducer. In order to meet the performance requirements of the car, this kind of scheme generally adopts a higher power motor. At present, the power density of the motor is not high, so the power of the motor is large, the size and quality must be large, which will inevitably have a negative impact on the performance of ...
