Steering mechanism of motor vehicle

Abstract

The present invention relates to a motor-vehicle steering mechanism. It includes an angle change-over device connected with vehicle body by means of mounting supporting frame, the input end of said angle change-over device is connected with input universal joint, its output end is connected with output universal joint. It is characterized by that between the described angle change-over device and vehicle body a fixed supporting frame is set, said fixed supporting frame is respectively connected with the described angle change-over device and symmetrical surface of said vehicle body by means of screw bolts. Besides, said invention also provides its working principle and concrete operation method.

Description

technical field [0001] The technical solution to be protected by the present invention relates to a steering mechanism of a motor vehicle. Background technique [0002] The steering of a motor vehicle is realized by controlling the steering wheel through the steering mechanism of the motor vehicle. The input drive of the steering wheel is the torque applied by the driver to the steering wheel; the drive transmission between the steering wheel and the wheel is through the steering shaft in the steering mechanism , universal joints, steering gears, steering rods, steering knuckles, etc. to achieve. Usually, due to the limited working angle of the universal joint, an angle converter can also be used to meet the angle requirements between the steering shafts. At present, the existing installation method is to directly fix the angle converter body on the vehicle body through bolts. [0003] As shown in Figure 3, the angle converter body is combined with the vehicle body. Althou...

AI Technical Summary

Problems solved by technology

Because the part is connected to the projection welding nut on the car body mounting bracket by bolts through the bolt holes on the body, the error caused by the manufacturing accuracy of the car body itself will cause the installation error of the angle converter, resulting in a steering error. Small changes in shaft arrangement angles cause fluctuations in the speed of the transmission shaft and affect steering performance

In addition, the angle converter itself bears a very strong load, but the rigidity of the bracket on which the angle converter is installed on the car body is not high, which may easily cause the angle converter to deform greatly during the loading process, or even fail; The spatial position of the input and output ends has a great influence on the angle of the steering shaft arrangement. The deformation of the mounting bracket on the car body will cause the position of the angle converter to move greatly, which directly causes the change of the angle of the steering shaft arrangement, resulting in the torque of the steering shaft, The fluctuation of the speed reduces the transmission efficiency and makes the steering not smooth
