Steering wheel driving system of diamond-type vehicle

Abstract

The invention relates to a diamond vehicle steering wheel driving system, comprising that two ends of a steering master pin arranged at the middle part of a lateral axis are connected with a steering knuckle which can rotate around an axis thereof; a wheel hub is arranged on the steering knuckle through a pair of supporting bearings; a spoke on one side of a wheel rim is fixed on one side of the wheel hub; a shell of a decelerator inside a cavity of the wheel rim consists of a left shell and a right shell; the left shell is fixedly connected with the steering knuckle, and the right shell is equipped on an external ring of the wheel hub through a bearing; one end of an inner half shaft inside the shell of the decelerator is linked with the wheel hub through a gear deceleration transmission pair, and the other end of the inner half shaft is connected with an end of a first constant speed universal joint of a ball cage; the other end of the first constant speed universal joint of a ball cage is connected with one end of a retractile outer half shaft; the other end of the retractile outer half shaft is connected with one end of a second constant speed universal joint of a ball cage. The invention can realize constant speed transmission of movement without interference of a transmission structure; the invention has large angle steering capability, beneficial for improving the road clearance of the vehicle.

Description

technical field [0001] The invention relates to a wheel side drive system of a motor vehicle, in particular to a wheel side drive system of a diamond-shaped single steering wheel. Background technique [0002] The existing vehicle steering drive axle is composed of the main reducer, differential, half shaft, universal joint, steering knuckle, kingpin, etc., and the power is transmitted to the left and right by the drive shaft, differential, half shaft, and universal joint in turn. The wheel is suitable for the front wheel on which two wheels are installed symmetrically left and right on a wheel shaft. For the application of only one steering drive wheel on the axle, such as a diamond-shaped chassis vehicle with only one steering drive wheel on the front and rear axles, the existing steering drive axle has the following problems: In view of the stress on the frame and the manipulation of the steering mechanism, it is advisable to adopt a left-right symmetrical double vertica...

AI Technical Summary

Problems solved by technology

For the application of only one steering drive wheel on the axle, such as a diamond-shaped chassis vehicle with only one steering drive wheel on the front and rear axles, the existing steering drive axle has the following problems: In view of the stress on the frame and the manipulation of the steering mechanism, it is advisable to adopt a left-right symmetrical double vertical pendulum structure (see invention patent CN101037116A) or a double-wish suspension similar to the front wheel of a motorcycle. The supporting horizontal shaft runs through the center of the wheel and the kingpin, occupying the position of the universal joint of the traditional steering drive axle and the position of the inner and outer half shafts, which is completely unsuitable for the existing steering drive axle
