By improving the driving structure in prior art, the rear wheel driving is changed to front wheel and rear wheel driving, namely four-wheel drive; in a rough terrain environment, if the rear wheels are suspended in the air or are not in contact with road surface or skid, the four-wheel drive electric vehicle can run through the front wheel driving, and the front box assembly is provided with a differential lock function, when the differential lock in the front box assembly is locked, the vehicle can be driven by a single front wheel, and the driving requirements for rough terrain situations are met.
Description
Technical field
The utility model belongs to a kind of battery-driven car.The battery-driven car that drives simultaneously of four-wheel specifically.
Background technology
At present, the type of drive of four-wheel electric motor car is a back-wheel drive, and the motor direct connection directly drives the gear in the rear axle speed-reducing case when motor rotates on the drop-gear box of back, by the two-stage gear reduction power is passed to semiaxis, drive wheels.Advantages such as this type of drive is used very extensively on the electric golf car, has compact conformation, and is easily manufactured.But along with the user to four-wheel electric motor car the improving constantly of operating needs under complex road condition, the battery-driven car of this back-wheel drive can not satisfy its requirement of travelling, as in more abominable road conditions environment such as forest, desert, marsh, in a single day vehicle is absorbed in motion and causes rear wheels slip just can't continue to travel in mud or the sand again.
The utility model content
The four-wheeled electric vehicle that provides a kind of front and rear wheel to drive simultaneously is provided technical problem to be solved in the utility model.
The technical solution of the utility model is as follows: a kind of four-wheeled electric vehicle comprises that before driving case, rear drive case, the wherein said before driving case of motor both sides are connected with front-wheel respectively through forecourt cage semiaxis; On the described rear drive case motor is installed, the output shaft of this motor is connected by spline with input shaft in the rear drive case, described rear drive case both sides are connected with trailing wheel respectively through the rear ball cage semiaxis, its key is: be connected with transmission shaft between the driving gear output shaft that stretch out driving gear input shaft that stretch out at described before driving case rear portion and rear drive case front portion, this transmission shaft one end is connected with the driving gear input shaft through forerunner's universal-joint, and the other end is connected with the driving gear output shaft through the rear-guard universal-joint.
Drive the driving gear output shaft when driven by motor trailing wheel rotates and rotate, the driving gear output shaft rotates drive driving gear input shaft and rotates, and rotates thereby drive with ball cage semiaxis bonded assembly front-wheel, realizes the four wheel drive of battery-driven car.
The driven fork female splines of above-mentioned forerunner's universal-joint end is sleeved on driving gear and comes in and goes out axle upward by nut locking, and the female splines suit transmission shaft front end of initiatively pitching of this forerunner's universal-joint welds.Above-mentioned transmission shaft rear end is sleeved on the driven fork male splines welding of rear-guard universal-joint, the output flange bolted connection of suit on the terminal pad of initiatively pitching the rear end of this rear-guard universal-joint and the driving gear output shaft.Forward and backward universal-joint driving gear input shaft, output shaft and the transmission shaft of driving connects more firm.
Above-mentioned output flange disk center is fixed on the transmission shaft by nut, and flange is locked.
Beneficial effect: the utility model structure is by the improvement to original drive configuration, it is four wheel drive that back-wheel drive is become that front and rear wheel can drive, situation is in abominable terrain environment, if trailing wheel is unsettled, do not contact with the road surface or skid, forward wd vehicle also can travel, and have the differential locking-device function in the preceding box assembly, with the differential locking in the preceding box assembly, depending merely on a front-wheel also can powered vehicle, satisfies the requirement of travelling under abominable road conditions.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the connection diagram of transmission shaft and forward and backward driving box in the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
