Abstract
The utility model discloses an automobile enhanced type universal joint fork, comprising a joint fork seat and two fork pins, wherein the two fork pins are arranged on the joint fork seat and are U-shaped; two bosses are arranged in the extension directions of the two fork pins towards the joint fork seat; each boss and the corresponding fork pin are integrated; a long and narrow crack is formed in each integral structure; and each long and narrow crack extends to a transmission shaft connection hole in the middle of the joint fork seat. The joint fork seat, the two fork pins and the long and narrow cracks of the automobile enhanced type universal joint fork are in an overall structure, so that the two fork pins can be enabled to have higher stress performance and be difficult in deforming; and during the use, the even transmission between each fork pin and a crossing shaft is guaranteed, so that greater transmission force can be effectively resisted. The automobile enhanced type universal joint fork is simple in structure and convenient to use; and through the strength enhancement of the joint fork, the strength and the service life of the whole universal joint is improved.
Description
Technical field
The utility model relates to a kind of universal joint of automobile technical field, and specifically, what relate to is the automobile reinforced universal joint fork.
Background technique
Car steering tube column has been related to the runnability of car load, and whether the quality of steering column directly has influence on turning to of Integral automobile steady.In the automobile steering pipe column system, three parts are arranged generally: steering shaft, steering column and transmission shaft, wherein transmission shaft partly has up and down two joint fork assemblies.And joint fork assembly is one of core component of motor turning transmission system, and the intensity of joint fork is directly to affect normal vehicle operation and whether turn to the key part of safety.
Joint under the prior art is pitched assembly at present, it has generally adopted a kind of Placement that fork matches with transmission shaft that saves, wherein the joint fork is for offering the spline joint fork of interior circular hole, offer again corresponding external splines pitching on the driving end that connects with joint on the transmission shaft, this transmission shaft is inserted the interior circular hole of joint fork, its external splines closely cooperates with the spline of the interior circular hole of joint fork, drives the running of joint fork by rotating drive shaft.
As shown in Figure 1, for existing a kind of joint fork comprises joint forked standard 1 and two fork pin 2,3, two fork pin are arranged on the joint forked standard and are the U font, be provided with the cross axle mounting hole at the fork pin, the bearing of trend of joint forked standard 1 corresponding two fork pin is provided with two boss, these two boss are provided with mounting hole, and be long and narrow seam between two boss, this long and narrow seam extends through the transmission shaft attachment hole in the middle of the joint forked standard 1 always, thereby two fork pin and corresponding boss are divided in this long and narrow seam one side, because this long and narrow seam without any assistant reinforcement, such structure has certain impact for the intensity of joint fork, thereby can affect the performance of whole automobile steering pipe column system.
The model utility content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and a kind of automobile reinforced universal joint fork is provided, and improves the intensity of joint fork, improves the Security of normal vehicle operation and steering operation.
For realizing above-mentioned purpose, automobile reinforced universal joint fork described in the utility model, comprise joint forked standard and two fork pin, two fork pin are arranged on the joint forked standard and are the U font, two fork pin have two boss to joint forked standard bearing of trend, described boss is integrated with corresponding described fork pin, at this integrative-structure one long and narrow seam is arranged, and this long and narrow seam extends through the transmission shaft attachment hole in the middle of the joint forked standard always.
Further, described long and narrow seam is arranged on the neutral position of described boss and corresponding described fork pin integrative-structure.
Further, described fork foot section is provided with the cross axle mounting hole, between described long and narrow seam and the described cross axle mounting hole segment distance is arranged.
Further, described joint forked standard, two fork pin and long and narrow seam are an overall structure.
The utility model joint forked standard, two fork pin and long and narrow seam are an overall structure, thereby can be so that two fork pin have higher stress performance, and be not yielding, in use guarantee and cross axle between transmission even, can effectively resist larger driving force.The utility model is simple in structure, and is easy to use, by having strengthened the intensity of joint fork itself, thus intensity and the life-span of having improved whole universal joint.

Embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is further explained, but following content is not used in restriction protection domain of the present utility model.
As shown in Figure 2, the present embodiment provides a kind of automobile reinforced universal joint fork, comprise joint forked standard 1 and two fork pin 2,3, two fork pin 2,3 are arranged on the joint forked standard 1 and are the U font, be provided with the cross axle mounting hole at fork pin 2,3, corresponding two the fork pin 2 of joint forked standard 1,3 bearing of trend are provided with two boss 4, and described boss is integrated with corresponding described fork pin, at this integrative-structure one long and narrow seam 5 is arranged, this long and narrow seam 5 extends through the transmission shaft attachment hole 6 in the middle of the joint forked standard 1 always.
In the present embodiment, described long and narrow seam 5 is arranged on the neutral position of described boss and corresponding described fork pin integrative-structure.
In the present embodiment, described fork pin 1 end is provided with the cross axle mounting hole, between described long and narrow seam 5 and the described cross axle mounting hole segment distance is arranged.
In the present embodiment, described joint forked standard 1, two the fork pin 2,3 and long and narrow seam 5 be an overall structure.
The present embodiment joint forked standard, two fork pin and long and narrow seam are an overall structure, to save forked standard, two structures that the fork pin is cut apart from a side with respect to the long and narrow seam of Fig. 1, strengthened the intensity of joint fork itself, thereby can be so that two fork pin have higher stress performance, not yielding, in use guarantee and cross axle between transmission even, can effectively resist larger driving force.The utility model is simple in structure, and is easy to use, by having strengthened the intensity of joint fork itself, thus intensity and the life-span of having improved whole universal joint.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
