Description
Technical field
The utility model relates to steering gear art, especially a kind of steering gear with New Buffering position-limit mechanism.
Background technology
Because steering gear is used work for a long time, and in the time that the anxious steering effort of steering gear is excessive or turn to left and right maximum angle, bulb limit body seat and metal shell generation moment fiercely impact, thereby make the position-limit mechanism distortion in steering gear or lost efficacy, and cause unsafe factor to increase.
Utility model content
In view of this, the utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of steering gear with New Buffering position-limit mechanism, and it can effectively improve service life and the security performance of steering gear.
For achieving the above object, the utility model adopts following technical scheme: a kind of steering gear with New Buffering position-limit mechanism, include and turn to housing, fan-shaped tooth sector, steering spindle, tooth sector axle and be arranged on the steering nut turning in housing, steering nut is connected with steering spindle, described steering spindle is provided with buffer limit mechanism, this position-limit mechanism includes shell body, tooth bar and bulb limit body seat, tooth bar is positioned at shell body, described bulb limit body seat is connected with tooth bar, this bulb limit body seat and tooth bar junction are provided with elastic washer, it is oval-shaped rubber ring that this elastic washer is provided with cross section towards tooth bar direction, between described shell body and tooth bar, be provided with metal spacing piece, this metal spacing piece and rubber ring are suitable.
As a kind of preferred version, described metal spacing piece is that independent monomer is installed on shell body.
As a kind of preferred version, described metal spacing piece is the extended limited block of shell body internal face one.
As a kind of preferred version, described cross section is oval-shaped rubber ring, and the oval short radius of its cross section is 1:2.3 with the ratio of oval major radius.
As a kind of preferred version, between described metal spacing piece and tooth bar, be provided with a gap.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly, in steering gear of the present utility model, be provided with New Buffering position-limit mechanism, it combines the function of elastic washer and rubber ring, in the time colliding with metal spacing piece, can effectively reduce collision dynamics, thereby when ensureing its limit effect, can effectively improve security performance and the shock-absorbing capacity of steering gear, and by the elliptic design to rubber ring, and use the optimal design that the oval short radius of its cross section and the ratio of oval major radius are 1:2.3, the elastic deformation producing in the time of strong collision can effectively absorb and cushion, reach the purpose of this utility model.

Detailed description of the invention
Please refer to shown in Fig. 1 to Fig. 3, it has shown the concrete structure of the preferred embodiment of the utility model, a kind of steering gear with New Buffering position-limit mechanism, include and turn to housing, fan-shaped tooth sector, steering spindle, tooth sector axle and be arranged on the steering nut turning in housing, steering nut is connected with steering spindle, described in the utility model to turn to housing, fan-shaped tooth sector, steering spindle, tooth sector axle and be arranged on the steering nut turning in housing be existing routine techniques, do not repeat at this.
Wherein, this steering spindle is provided with buffer limit mechanism 10, this position-limit mechanism 10 includes shell body 11, tooth bar 12 and bulb limit body seat 13, this tooth bar 12 is positioned at shell body 11, this bulb limit body seat 13 is connected with tooth bar 12, this bulb limit body seat 13 is provided with elastic washer 14 with tooth bar 12 junctions, it is oval-shaped rubber ring 15 that this elastic washer 14 is provided with cross section towards tooth bar 12 directions, this cross section is oval-shaped rubber ring, and the oval short radius of its cross section is 1:2.3 with the ratio of oval major radius.
Between this shell body 11 and tooth bar 12, be provided with metal spacing piece 16, this metal spacing piece 16 is suitable with rubber ring 15. This metal spacing piece 16 is the extended limited block of shell body internal face one; Can effectively promote the service life of metal spacing piece 16 and the security performance of steering gear; Between this metal spacing piece 16 and tooth bar 12, be provided with a gap 17.
Design focal point of the present utility model is, in steering gear of the present utility model, be provided with New Buffering position-limit mechanism, it combines the function of elastic washer and rubber ring, in the time colliding with metal spacing piece, can effectively reduce collision dynamics, thereby when ensureing its limit effect, can effectively improve security performance and the shock-absorbing capacity of steering gear, and by the elliptic design to rubber ring, and use the optimal design that the oval short radius of its cross section and the ratio of oval major radius are 1:2.3, the elastic deformation producing in the time of strong collision can effectively absorb and cushion, reach the purpose of this utility model.
More than should, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore every foundation technical spirit of the present utility model, to any trickle amendment made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solutions of the utility model.
