Embodiment Construction

[0021] As shown in Figure 1, the vehicle controller 5 controls the engine controller 9 through the wire harness 8, and the engine controller 9 controls the engine 14 to work through the wire harness 7; the output of the engine 14 is connected to the speed change mechanism 15 and the transmission mechanism 10 to drive the drive shaft 16, The drive shaft 16 drives the wheels to move the vehicle.

[0022] The vehicle controller 5 controls the motor controller 3 through the wiring harness 4, the motor controller 3 controls the driving motor 12 through the wiring harness, drives the driving shaft 1 through the transmission mechanism 11, and the driving shaft 1 is connected to the wheels and rotates to move the vehicle. This is the first electric drive system. The motor controller 3 controls the drive motor 19 through the wiring harness 20, drives the drive shaft 17 through the speed change transmission mechanism 18, and the drive shaft 17 is connected to the wheels; rotating to mak...

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...
