Description
Technical field
The present invention relates to a kind of mixed power automobile driving system, particularly relate to a kind of distributed arrangement and adopt the mixed power electric car drive system of band transferring power synchronously.
Background technology
Modern oil electric mixed dynamic electronlmobil generally is divided into three kinds of tandem, parallel and series parallel types.They all adopt to concentrate the motor-driven scheme without exception, are delivered to wheel through transmission shaft, main reduction gear again after promptly having the power of a high-performance main drive motor and driving engine to be coupled through dynamic coupling device power.For satisfying the automotive performance requirement, the general motor of this kind scheme adopts power bigger.Power of motor density is not high at present, so power of motor is big, and size, quality must be very big; Certainly will cause harmful effect to vehicle performance like this; And motor arranges in car and dumb, has influence on interior space possibly, and the traveling comfort of automobile is produced harmful effect.
Slowdown type wheel limit power drive system is comparatively later-model at present electronlmobil transmission scheme, and promptly each drive motor is arranged near each drive wheel, through direct drive wheel behind the speed reduction gearing.Owing to can all arrange wheel motor by each drive wheel, so the optional lower-powered motor of wheel motor.And wheel limit power drive system has omitted the devices such as power-transfer clutch, universal-joint, transmission shaft and diff of orthodox car, and it is compared concentrate motor-driven that special advantages is arranged: succinct, the capable of using space of complete vehicle structure is big; Messenger chain is short, the drive system driving efficiency is higher, and each driving wheel torque is independent controlled, and the chassis system dynamics Controlling is more flexible, convenient etc.But take turns the limit power drive system at present owing to the multi-stage gear transmission is adopted in the requirement of width between centers and transmitting ratio; Increased the unsprung weight of vehicle; Cause the undesirable of vehicle performance, and because the requirement of carrier gear precision drive has caused the raising of sealing and lubricated cost.
Band is a kind of new type transmission belt synchronously, grows up combining strap drive, chain gear and gear-driven advantage.Owing to be to utilize band tooth driving surface and belt wheel teeth groove engagement carrying out transmission, therefore be with and belt wheel between in transmission process, do not have slippage and present synchrodrive.Compare with traditional V band that to have a belt body light and approach, intensity is high, and transmitting ratio is accurate, the driving efficiency height, and the transmission power scope is big, the transmission speed advantages of higher.Compare with chain gear have net synchronization capability good, need not to lubricate, in light weight, advantage such as cost low and maintenance is convenient.Thereby its development is very fast, and has replaced other types strap drive or chain-driving in some specific occasions, has been widely used in fields such as light industry and machinery, chemical industry, computing machine and universal machine at present.But only be confined to control on the camshaft actuated of engine valve in the application on the automobile at present.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of mixed power electric car drive system that adopts synchronous strap drive, and distributed gear transmission of taking turns in the power drive system of limit is replaced with synchronous strap drive.
In order to solve above technical matters, the invention provides a kind of mixed power electric car drive system that adopts synchronous strap drive, promptly front-wheel provides power by driving engine, and each trailing wheel all has a cover wheel limit power drive system that power is provided.Concrete transmission scheme is: the trailing wheel power drive system by front-wheel engine drive system and two groups of independent controls is formed; Wherein, The front-wheel drive system turnkey is drawn together driving engine, power-transfer clutch, change-speed box and main reduction gear; The same with preposition forerunner's orthodox car, the power of driving engine drives front-wheel through power-transfer clutch, change-speed box, main reduction gear transmission.
The trailing wheel power drive system comprises that power accumulator, two wheel motors and two groups are with speed reduction gearing synchronously; Power accumulator is the wheel motor power supply through being electrically connected; The housing of wheel motor and suspension simple pendulum arm are fixed, and the rotor of output shaft axle and the small pulley of wheel motor connect firmly, and semiaxis one end connects firmly with big belt wheel; Big small pulley is through band connection synchronously, and the semiaxis other end and drive wheel wheel hub connect firmly; The wheel motor output torque through synchronous band small pulley, synchronously band, be with big belt wheel to be passed to semiaxis and wheel hub synchronously, and drive trailing wheel; No direct mechanical contact between driving engine and the wheel motor, they realize the conversion of automobile drive pattern through entire car controller.
Said suspension simple pendulum arm is suspension single longitudenal arm or suspension monocline arm.
The invention has the beneficial effects as follows:
1) adopt the distributed hybrid power drive scheme of this kind can make complete vehicle quality distribute rationally, all dynamic output of front and back wheel and constitute all-wheel drive, vehicle performance is more good.Than the all-wheel driven vehicle of transmission, mechanism simplifying, driving efficiency is high, and the formation hybrid vehicle greatly improves vehicle economy;
2) the distributed hybrid power drive scheme of this kind is more suitable for the repacking of traditional combustion engine automobile to new-energy automobile.Because the new-energy automobile development difficulty is bigger, therefore be undoubtedly way the most convenient and reality to the repacking of new-energy automobile by traditional internal-combustion engines vehicle.And the distributed drive system of this kind can keep preposition forerunner's conventional engines Power train fully; Only being required to be trailing wheel installs two groups of independent controls additional and by the wheel limit power drive system of synchronous band deceleration transmission, therefore very is fit to the repacking of traditional vehicle to new-energy automobile;
3) adopt wheel limit power drive system than concentrated motor-driven flexible arrangement, messenger chain is short, the drive system driving efficiency is higher, and each driving wheel torque is independent controlled, and the chassis system dynamics Controlling is more flexible, convenient;
4) will take turns limit power drive system speed reduction gearing adopts synchronous strap drive can satisfy the width between centers requirement of wheel limit power drive system better than gear transmission; Designs simplification helps reducing of vehicle unsprung weight, therefore helps the ride comfort and the road-holding property of automobile; And because strap drive efficient is high synchronously; Adaptive capacity is strong, and need not lubricate and seal, so cost is cheaper.
