Multiple shaft driving mixed power automobile driving system

Abstract

The invention discloses a multi-shaft driving mixed power automobile driving system, comprising an engine first power source, an engine output connection transmission mechanism, a transmission mechanism output connection transmission mechanism which drives a first driving shaft, and at least a set of power source different from the engine power source; the set of power source outputs and is connected with a speed change transmission mechanism, which outputs and is connected with a driving shaft different from the first driving shaft. Owning to a plurality of axles, the bearing capability of a vehicle is greatly improved and is not restricted; the structure of the invention is simple, which cancels a complex divider; the combination of motor driving and engine driving is various, and the control is flexible. On the precondition of ensuring the country-crossing and trafficability of the vehicle, the invention can greatly improve the bearing capability of the vehicle, implements the optimization of the energy utilization, reduces the complexness of the system, improves the power and brake performance of the vehicle, reduces the energy loss and exhaust, lightens the weight of the vehicle, and reduces the manufacture cost.

Description

technical field [0001] The invention belongs to a hybrid power device, in particular to a hybrid power drive system, that is, a multi-shaft drive hybrid power vehicle drive system. Background technique [0002] Most of the existing multi-axle drive vehicles are a power source that transmits power to multiple drive shafts through the transfer device to realize power distribution, and use the road surface adhesion as much as possible to improve the off-road performance, power performance, braking performance and passability of the vehicle. At the same time, the axle load distribution is improved, but the energy utilization efficiency of this scheme is very low, resulting in the need for a high-power power plant to meet the requirements, which makes the vehicle structure complex, weight increases, energy consumption increases, emissions deteriorate, and the cost is high No more. [0003] Using hybrid drive technology can better solve the above problems. The hybrid drive syste...
