Description
Technical field
The invention belongs to technical field of power transmission, be specifically related to a kind of vehicle hybrid power drive system.
Background technology
Multi Axle Drive Vehicle axle load distributes rationally, dynamic property and crossing ability strong, be widely used in heavily loaded wheeled car and wheel military vehicle.Along with the raising that mobility performance and control stability require, Multi Axle Drive Vehicle needs more urgent to the power flexible allocation between centers and wheel.The flexible allocation of between centers power, can make full use of the adhesive ability on road surface, promotes acceleration capacity; Power distribution between wheel is got rid of poverty except anti-skidding, can also realize the fixed direction allocation of torque between taking turns, improve the yaw acceleration of vehicle, promoted the maneuvering performance of curved process.
Traditional Multi Axle Drive Vehicle, mostly adopt a propulsion source (as driving engine) by transfer system by transmission of power to multiple axle drive shaft, realize distribution between the between centers of power and wheel.Publication number CN101186180A patent of invention adopts two kinds of propulsions source, driving engine and battery; Engine drive first axle, the form of motor drive motor drives the second axle, the 3rd axle, solves the flexible allocation of power between centers, but cannot realize the flexible allocation between wheel.Realize utilizing as far as possible road adherence to provide the cross-country traveling ability of multiple-axle vehicle, dynamic property and road-holding property, improve axle load simultaneously and distribute, must realize power freely distributing between centers and wheel, this needs the transfer system of complexity.For 8 × 8 vehicles, if need car load to realize the full harmony of motion, need 4 inter-wheel differentials and 3 interaxle differentials; Suppose all to realize with open type differential, as a certain wheel loses adhesive ability at Special Road, all wheels can be caused to run out of steam; Although the diff (comprising E-Diff) of available locking device or anti-skid final drive realize the traveling on difficult road surface, its physical construction and control complexity.Torsional differential gear etc. are with the diff of Torque distribution function, although may be used for the power distribution of between centers, it can only realize narrow power distribution, also cannot realize the flexible allocation between 0 ~ 100%.
Summary of the invention
The object of the invention is: provide a kind of three axles to five shaft-driven vehicle hybrid electric drive system systems, solve power distribution between the between centers on accelerator or difficult road surface and wheel; Retain the mechanical drive of wherein an axle or diaxon simultaneously, ensure the driving efficiency under high-speed working condition.
