Abstract
The utility model discloses a deceleration system of a four-wheel drive electric automobile, comprising a car frame; the car frame is provided with a speed change transfer case, a front axle assembly and a rear axle assembly; the speed change transfer case is installed at the rear part of the car frame; a motor is vertically arranged and installed above the speed change transfer case; the front axle assembly is installed at the front part of the car frame; the rear axle assembly is installed at the rear part of the car frame; a transmission shaft is installed between the output shaft of the speed change transfer case and the front axle assembly for connecting and transferring a front driving force; the motor transfers the power to the speed change transfer box through the output shaft of the motor and transfers part of the power to the front axle assembly after the primary deceleration of the speed change transfer case internally provided with a front wheel for deceleration, and then transfers the power to a left front wheel and a right front wheel through a front axle left half axle and a front axle right half axle; a back wheel for deceleration is integrally provided with the speed change transfer case; the other part of the power is directly transferred to the rear wheel for deceleration through the primary deceleration and then transferred to a rear axle rear half axle and a rear axle right half axle through the rear axle assembly, and then the power is transferred to a left rear wheel and a right rear wheel.
Description
Technical field
The utility model relates to a kind of electronlmobil deceleration system, relates in particular to a kind of electronlmobil deceleration system of motor postposition four wheel drive.
Background technology
At present; because the generation of energy shock reaches the pay attention to day by day to environmental protection; countries in the world begin to develop pure electric automobile one after another; the style of electronlmobil is also more and more; but common pure electric automobile mostly is two-wheel drive at present; and the customer is based on the demand of aspects such as wet and slippery ice and snow road and uneven ground-surface crossing ability, climbing property, straight motion stability, startup and acceleration capability; the demand that the electronlmobil that four wheel drive need be provided is arranged; therefore just must consider the deceleration system of four-wheel driving electric vehicle; make its space layout reasonable, compact conformation.
The utility model content
Problem to be solved in the utility model provides a kind of compact conformation, rationally distributed four-drive electric car deceleration system.
The technical scheme that the utility model adopted is: the four-drive electric car deceleration system, comprise vehicle frame, the speed change part-time case is installed on the described vehicle frame, front axle assy, back axle assembly, described speed change part-time case is located at the vehicle frame rear portion, described motor adopts vertical putting, be installed on speed change part-time case top, described front axle assy is located at the vehicle frame front portion, described back axle assembly is located at the vehicle frame rear portion, described speed change part-time case output shaft, be provided with transmission shaft between the front axle assy and be used for connecting transmission forerunner power, described motor arrives the speed change part-time case by motor output shaft with transmission of power, after the deceleration of speed change part-time case one-level, described speed change part-time case is delivered to front axle assy with a part of power by transmission shaft, being provided with front-wheel in the described front axle assy slows down, after forerunner's dynamic retarding is finished in the front-wheel deceleration, again by the propons left half axle, the propons right axle shaft finally is delivered to the near front wheel with power, off front wheel; Described trailing wheel slows down and the speed change part-time case is installed as one, another part power then slows down directly transmission of power to be slowed down to trailing wheel by one-level and finishes the rear-guard dynamic retarding, described speed change part-time case output shaft is connected with back axle assembly, give back axle half-rear axle, back axle right axle shaft through back axle assembly with transmission of power, again power finally is delivered to left rear wheel, off hind wheel.
In the such scheme, described motor can adopt DC machine, can certainly adopt alternating current dynamo.
In order to protect transmission shaft, avoid being damaged by the uneven ground scratching, be provided with the protective tube more than in below the described transmission shaft or the left and right sides.
The beneficial effects of the utility model are: the utility model provides the deceleration system on a kind of rearmounted motor four-wheel driving electric vehicle chassis, simple and reliable for structure, energy-conserving and environment-protective, maintenance is convenient, economical and practical, compact conformation, spatial destribution is reasonable, the weight configuration is rationally balanced, can be widely used in for example four-wheel driving electric vehicle of various uses such as cross-country car, vehicle for hunting.
