Abstract

A series-parallel hydraulic drive hybrid power vehicle power assembly system belongs to the technical field of vehicle driving devices and aims at solving the problems in the prior art of complex structure shape, large control difficulty and high manufacture cost. The system comprises a front axle load wheel transmission portion, a rear axle load wheel transmission portion, a vehicle main controller, an engine, a brake controller, a transmission shaft and a hydraulic transmission system. The output end of the brake controller is connected with a front axle friction brake I and a front axle friction brake II of the front axle load wheel transmission portion and a rear axle friction brake II and a rear axle friction brake I of the rear axle load wheel transmission portion, the output end of the engine is connected with the transmission shaft, and the vehicle main controller controls output power of the engine and conducts matching adjustment on output power of the hydraulic transmission system by receiving torque values of a front axle torque sensor of the front axle load wheel transmission portion and a rear axle torque sensor of the rear axle load wheel transmission portion.

Description

technical field [0001] The invention belongs to the technical field of automobile driving devices, and in particular relates to a power assembly system of a hybrid liquid-driven hybrid vehicle. Background technique [0002] With the continuous increase of the number of cars in our country, the shortage of petroleum resources, the serious urban traffic congestion, and the serious excess of vehicle exhaust emissions, the above problems have posed a serious threat to people's daily life and social energy environment. Throughout the history of automobile development, it can be seen that the traditional vehicle transmission system is mainly composed of the engine, gearbox, drive shaft, differential and wheels. Deceleration or braking, so that the braking energy is completely converted into heat energy and lost. At the same time, the engine drive shaft is disconnected from the load, causing the engine to stall instantaneously, causing the engine to not be in the best fuel economy ...
