The steering linkage of tooth bar connection, is provided with stopping means between the steering linkage and housing, the stopping means include spring
Body, the spring body is placed on the steering gear rack.
Steering gear of the present utility model, wherein, the stopping means also include being connected to the two ends of the spring body
The first check ring and second spring back-up ring, first check ring is placed on the steering gear with second spring back-up ring
On tooth bar, first check ring is fixedly connected with the steering linkage.
Steering gear of the present utility model, wherein, steering linkage is threaded togather by ball cup with steering gear rack,
The ball cup is fixedly connected with the steering linkage, is provided with screw thread mounting groove on the outer face of the ball cup, described turn
Stretch in the screw thread mounting groove to device tooth bar, by the appearance of the screw thread in the screw thread mounting groove and the steering gear rack
The cooperation of the screw thread in face, the ball cup is threaded togather with steering gear rack, and first check ring is connected to institute
State on the outer face of ball cup.
Automobile of the present utility model, including steering gear of the present utility model.
The technical solution of the utility model, when steering gear goes to extreme position, spring body is contacted with housing, contact
During spring compressed, spring absorbs impulsive force when clashing into, and so as to reducing impact force, reduces the biography of strike note and impact force
Pass.
Description of the drawings
Fig. 1 is the structural representation of steering gear of the present utility model；
Fig. 2 is the structural representation of stopping means.
Specific embodiment
As shown in Figure 1 and Figure 2, steering gear of the present utility model, including housing 1, the steering gear rack 2 being arranged in housing 1
And the steering linkage 3 being connected with steering gear rack 2, stopping means 4, stopping means are provided between steering linkage 3 and housing 1
4 include spring body 5, and spring body 5 is placed on steering gear rack 2.
Steering gear of the present utility model includes spring body, and when steering gear goes to extreme position, spring body is carried out with housing
Contact, spring is compressed in contact process, and spring absorbs impulsive force when clashing into, so as to reducing impact force, reduce strike note and
The transmission of impact force.
Steering gear of the present utility model, wherein, stopping means 4 also include being connected to the first of the two ends of spring body 5
Check ring 11 and second spring back-up ring 12, the first check ring 11 is placed on steering gear rack 2 with second spring back-up ring 12
On, the first check ring 11 is fixedly connected with steering linkage 3.
Steering gear of the present utility model, wherein, steering linkage is threaded in one by ball cup 6 and steering gear rack 2
Rise, ball cup 6 is fixedly connected with steering linkage 3, and screw thread mounting groove is provided with the outer face of ball cup 6, and steering gear rack 2 is stretched
Enter in screw thread mounting groove, by the cooperation of the screw thread in screw thread mounting groove and the screw thread of the outer surface of steering gear rack 2, ball cup 6
It is threaded togather with steering gear rack 2, the first check ring 11 is connected on the outer face of ball cup 6.
Automobile of the present utility model, including steering gear of the present utility model.
The technical solution of the utility model increased stopping means on steering gear rack, and stopping means include two springs
Back-up ring and a spring body, are compressed when ball cup is threadedly coupled with steering gear rack to spring body so that spring body is produced
Certain compression, certain pretightning force is produced because spring body compresses, so when steering gear works, steering gear rack movement
Drive stopping means to move together, when steering gear rack is moved to extreme position, the check ring of stopping means first with turn
Spacing end face to the housing of device is contacted, existing certain compression before contact due to spring body, there is certain pre-
Clamp force, check ring is acted on the confined planes of housing and will produce certain counteracting force after contact, reduces steering gear rack
Translational speed, but steering gear rack will not be caused to stop movement immediately, the impact force for thus making steering gear rack is gradually cut down, from
And reduce strike note of the steering gear rack end face to the confined planes of steering gear housing.
When beating direction soon when the technical solution of the utility model improves driver original place and low speed, steering gear rack and
The situation that housing clashes into, and have certain protective effect to steering gear rack and housing, increased the reliability of product.
The technical solution of the utility model, evaluates from car load NVH angles, hitting when improving steering gear rack extreme position
Sound is hit, increases the satisfaction of driver, and also function to the effect reminded driver, prevent driver from working as at steering gear rack
Pound direction when extreme position, while to playing a part of protection to steering.
The above is only preferred implementation of the present utility model, it is noted that for the ordinary skill people of the art
For member, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improvements and modifications
Also should be regarded as protection domain of the present utility model.
