Embodiment Construction

[0018] The present invention as figure 1 , 2 shown.

[0019] A steering gear that reduces the movement space of the vehicle body turning mechanism, including a steering gear 6, a cylindrical housing 4 is arranged outside the housing of the steering gear 6 with an output shaft end, and a spline sleeve 5 and an output shaft are connected inside the cylindrical housing 4. The shaft is socketed, and the other end of the spline sleeve 5 is socketed with an extension shaft 3, and the extension shaft 3 extends out of the cylindrical shell 4, wherein the extension shaft 3 is provided with a deep groove bearing support 2 at the port of the cylindrical shell 4 .

[0020] The deep groove ball bearing 2 is provided with a skeleton seal 1 outward, and the end face of the cylindrical housing 4 is provided with a dustproof oil seal 9 .

[0021] The outer ring of the deep groove ball bearing 2 is fixed inside the cylindrical housing 4 by a snap spring 7 , and the inner ring of the deep gro...

Abstract

The invention provides a steering gear capable of reducing the motion space of a small vehicle body turning mechanism. The steering gear comprises a steering gear body and is characterized in that a cylindrical shell is arranged outside a shell at the output shaft end of the steering gear body, the inner portion of the cylindrical shell is connected with an output shaft through a splined hub in a sleeved mode, the other end of the splined hub is connected with an extension shaft in a sleeved mode, the extension shaft extends out of the cylindrical shell, and the extension shaft is provided with a deep groove ball bearing at the end opening portion of the cylindrical shell; the deep groove ball bearing is provided with a framework seal outwards, and an anti-dust oil seal is arranged on the end face of the cylindrical shell; the outer circle of the deep groove ball bearing is fixed to the interior of the cylindrical shell through a snap spring, and the inner circle of the deep groove ball bearing is fixed onto a shaft neck of the extension shaft through a steel cable baffle ring. Through schematic design and development of the extension structure, the problems that a steering gear is stuck and the gap of the steering gear is large due to the fact that an extension structure is additionally arranged are solved. The steering gear is simple in structure, saves space, facilitates finished automobile arrangement and conforms to the requirement for finished automobile development.

Description

technical field [0001] The invention relates to a steering system of an automobile, in particular to a steering gear which reduces the movement space of a vehicle body turning mechanism. Background technique [0002] The current design of the steering gear is limited by the small car models in the past, and the requirements for the length of the input shaft of the steering gear are relatively low. Generally, the requirements for turning over the cab can be obtained by adjusting the steering column. [0003] With the upgrading of models, the gradual development of large models has become a trend. Simply adjusting the length of the steering column can no longer meet the requirements for the turning angle of the cab. Contents of the invention [0004] In order to utilize the existing steering gear to realize the overturning of the cab of a large vehicle, the present invention proposes a steering gear which reduces the movement space of the vehicle body overturning mechanism. ...
