Vehicle auxiliary drive mechanism

Abstract

The invention discloses a vehicle auxiliary drive mechanism which comprises an engine, a transmission, a first clutch, a vehicle speed sensor and a controller. The first clutch is connected between the engine and the transmission. An output end of the transmission is connected with a differential mechanism through a reduction gear set. A position sensor is disposed on the first clutch. The output end of the transmission is connected with an input shaft of an accumulation transmission system through a second clutch which is connected with a brake pedal. An output shaft of the accumulation transmission system is provided with an accumulation coil spring and a locking device. The output shaft of the accumulation transmission system is connected with the differential mechanism through an auxiliary drive transmission system which can transmit power unidirectionally. The vehicle speed sensor and the position sensor are connected with an input end of the controller. An output end of the controller is connected with the locking device. By the vehicle auxiliary drive mechanism, brake energy during traveling of fuel vehicles can be fully absorbed, stored and used for driving vehicle starting, starting performance of the vehicles can be improved favorably, and oil consumption and emission can be lowered evidently.

Description

[0001] technical field [0002] The invention relates to an auxiliary driving device for a vehicle, in particular to a vehicle driving auxiliary mechanism which can store vehicle braking energy and use it for auxiliary driving when starting, and a corresponding driving auxiliary method. [0003] Background technique [0004] Vehicles need frequent braking and starting during driving. Existing vehicle braking is usually achieved by hydraulically driven brake calipers clamping brake pads that are coaxial with the wheel shaft. Since the brakes rely on brake calipers The friction between the brake disc and the brake disc is completed. Therefore, frequent braking will cause the wear of the brake calipers and brake discs and other braking devices, which need to be replaced after a period of use, and the inertial kinetic energy of the vehicle during the braking process is lost Convert it into heat energy and waste it in vain. In addition, when the vehicle is restarted after braki...

Problems solved by technology

[0008] The object of the present invention is to provide a fuel-fueled vehicle that can be used to drive the vehicle to overcome the problems that the existing vehicle auxiliary drive device cannot significantly reduce the fuel consumption of the engine and that the braking energy cannot be directly used to drive the vehicle on the fuel vehicle. Vehicle drive-assisting mechanism and method for directly absorbing and storing braking energy during driving and using it to drive the vehicle to start
