Abstract
The utility model relates to a steering gear limiting block. The steering gear limiting block is characterized in that a rack is located in the steering gear shell body, the front end of the rack is fixedly connected with a steering inner pull rod ball head seat, the rack and the steering gear shell body are limited through a limiting structure composed of a split type inner side limiting block, an elastic layer, and a split type outer side limiting block, the split type inner side limiting block is an inner layer of the limiting structure, the split type outer side limiting block is an outer layer of the limiting structure, the direction corresponding to the steering inner pull rod ball head seat is the outer side of the limiting structure, the elastic layer is arranged between the split type inner side limiting block and a split type outer side limiting block, and a resin coating is arranged on the outer side end face of the split type outer side limiting block. The steering gear limiting block improves the returning performance of a finished automobile at in-situ steering time and low-speed steering time through extra returning force generated by the elastic limiting structure added between the steering shell body and the rack, prevents harsh metal knocking sound from being generated at contact time of the steering pull rod inner ball head seat and the limiting block, and improves the NVH performance of the finished automobile.
Description
Technical field
The utility model relates to a kind of deflector limiting stopper, belongs to the technical field of rack and pinion steering gear.
Background technology
At present, rack and pinion steering gear is widely adopted on manned vehicle, and limiting stopper is installed on steering gear housing, determines the rack stroke of deflector by mechanical position limitation, is plain metal entity structure.Park or when wide-angle turns to, in steering track rod, ball cap contacts with limiting stopper, produces ear-piercing metal knock when original place, can make chaufeur take for to turn to abnormal sound or chassis to turn to time, interfere abnormal sound, affect the quality of car load; In addition, vehicle is in pivot stud or the speed of a motor vehicle when lower, and return performance is all poor.
Summary of the invention
The purpose of this utility model is to provide a kind of deflector limiting stopper, and it is by adding resilient position limiting structure to produce extra Hui Zhengli between steering gear housing and tooth bar, improved car load original place and low speed rotation to time return performance; Prevent from producing ear-piercing metal knock when ball cap contacts with limiting stopper in steering track rod simultaneously, improve car load NVH performance.
The technical solution of the utility model is achieved in that a kind of deflector limiting stopper, it is characterized in that: tooth bar is positioned at steering gear housing, the front end of tooth bar is fixedly connected with turning to draw-in bar ball cap, split type inner side limiting-position piece, elastic layer, the position limiting structure of split type outside limiting stopper composition is to spacing between tooth bar and steering gear housing, the internal layer that split type inner side limiting-position piece is position limiting structure, the skin that split type outside limiting stopper is position limiting structure, position limiting structure turns to draw-in bar ball cap direction take correspondence as outside, between split type inner side limiting-position piece and split type outside limiting stopper, it is elastic layer, outside the limiting stopper of split type outside, end face has resinous coat.
Described elastic layer can be spring or rubber.
Good effect of the present utility model is that it is by adding resilient position limiting structure to produce extra Hui Zhengli between steering gear housing and tooth bar, improved car load original place and low speed rotation to time return performance, prevent from producing ear-piercing metal knock when ball cap contacts with limiting stopper in steering track rod simultaneously, improve car load NVH performance.
Accompanying drawing explanation
Fig. 1 is sectional structure chart of the present utility model.
Fig. 2 is position limiting structure Local map of the present utility model.
The specific embodiment
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.A kind of deflector limiting stopper, it is characterized in that: tooth bar 2 is positioned at steering gear housing 1, the front end of tooth bar 2 is fixedly connected with turning to draw-in bar ball cap 7, split type inner side limiting-position piece 3, elastic layer 4, the position limiting structure that split type outside limiting stopper 5 forms is to spacing between tooth bar 2 and steering gear housing 1, the internal layer that split type inner side limiting-position piece 3 is position limiting structure, the skin that split type outside limiting stopper 5 is position limiting structure, position limiting structure turns to draw-in bar ball cap 7 direction take correspondence as outside, between split type inner side limiting-position piece 3 and split type outside limiting stopper 5, it is elastic layer 4, limiting stopper 5 outside end faces in split type outside have resinous coat 6.
Described elastic layer 4 is spring or rubber.
As shown in Figure 1, when tooth bar 2 drives while turning to draw-in bar ball cap 7 to be moved to the left to end position, because end face outside position limiting structure has resinous coat 6, can eliminate the noise that metal clashes into; Elastic layer 4 both sides connect respectively split type inner side limiting-position piece 3 and split type outside limiting stopper 5, allow to produce a certain amount of elastic deformation at tooth bar 2 axis directions of deflector after compression.In the time redirecting to the end position of tooth bar 2, the elastic layer 4 in the middle of position limiting structure is compressed generation elastic deformation, has accumulated elastic potential energy; In the time that chaufeur unclamps steering handwheel, elastic potential energy discharge, produce extra Hui Zhengli, improved car load original place and low speed rotation to time return performance.
Claims (2)
1. a deflector limiting stopper, it is characterized in that: tooth bar is positioned at steering gear housing, the front end of tooth bar is fixedly connected with turning to draw-in bar ball cap, split type inner side limiting-position piece, elastic layer, the position limiting structure of split type outside limiting stopper composition is to spacing between tooth bar and steering gear housing, the internal layer that split type inner side limiting-position piece is position limiting structure, the skin that split type outside limiting stopper is position limiting structure, position limiting structure turns to draw-in bar ball cap direction take correspondence as outside, between split type inner side limiting-position piece and split type outside limiting stopper, it is elastic layer, outside the limiting stopper of split type outside, end face has resinous coat.
2. a kind of deflector limiting stopper according to claim 1, is characterized in that described elastic layer is spring or rubber.
