Abstract
The utility model provides a four-wheel drive motor with four independent suspension wheels, which is characterized in that four independent suspension assemblies are respectively connected with a frame; various wheels are ensured to jump up and down in a large range and are fully driven. The four-wheel drive motor comprises a main driving source which is arranged at the rear part of the frame and is connected with a rear reducer, a prodromal frontal gimbal, a prodromal back gimbal and a prodromal torsion output part of a prodromal universal rod, which is used for connecting with the rear reducer; the prodromal torsion is transmitted into a predecessor box in which an electric clutch is arranged. The prodromal universal rod adopted by the utility model can overcome the defects of the transmission of driving force by a chain pitch wheel, and all the driving force can be completely transmitted into a frontal wheel. The four-wheel drive motor can be fully driven both by four wheels and rear drive; two frontal wheels only make free rolling, thereby reducing the unwanted energy exhaustion.
Description
Technical field
The utility model relates to the structure of battery-driven car, and the structure that particularly direct current motor driven battery-driven car drives relates in particular to the battery-driven car of four-wheel independent suspension, powerdriven structure between the front and back wheel.
Background technology
In the prior art, the super-mini structure of existing wheel independent suspension.
For example Chinese utility model patent ZL 94231366.6, disclosed a kind of name is called the technical scheme of " the hinged quasi-parallel swing of mini-car independent suspension propons ", what this scheme disclosed is: the alternative original axle beam of an elongated resilient steel plate at first is set connects two front-wheels, the middle part of this steel spring is fixed on the vehicle body heavy frame, top link links to each other with steel spring with the hinge joint mode with the load connecting arm, constitutes front wheel arm and swings near parallelogram.The power connecting arm connects stabilizer rod simultaneously, steel spring, and spindle arm and three bulbs under any circumstance all can be done rotation about 90 ° around steering shaft, when a side wheel tire is subjected to impacting, opposite side are not had big influence, can not influence the running state of automobile.
By in the drawing and description of this patent documentation as can be seen, this vehicle body heavy frame is the oblong cross section, relevant between the buffer zone of wheel bob with the side edge length in this oblong cross section, the elasticity of buffering comes from steel spring, its elastic range has also limited can be very not big between the buffer zone of wheel bob, and this is one of shortcoming.
Again because this patent is born the pressure of propons with steel spring, center fixed vehicle body heavy frame on steel spring again so limiting device will be set, links to each other between steel spring and vehicle body heavy frame, avoid excessive impulsive force that steel spring is damaged, this is two of a shortcoming.
Again because steel spring is the parts of two wheels of an elongated connection, thus this technical scheme be independent suspension some is inadequate, in rugged especially travels down, two wheels of this patent have bigger interacting.
In addition when realizing four wheel drive because design need be provided with driving engine the rear portion of car, in the prior art by after transmit power forward, generally all transmit with chain pitch wheel.Shortcoming with chain pitch wheel transmission is, after chain pitch wheel transmission period of service was of a specified duration, it is lax that the chain pitch wheel transmission can become, and the front and back transmission has just had a time difference, makes to control to drive not due play to occur.
Having is exactly battery-driven car of the prior art again, owing to reason on the structure, generally all is designed to hoop and stops.Hoop is stopped and is occurred locking phenomenon easily.
