Model utility content
The utility model aims to provide a kind of wear-resisting automobile one or two gear shift fork, increases the service life, and can Reusability after passing through injection moulding again.
For this reason, the technological scheme that the utility model adopts is: a kind of automobile one or two keeps off shift fork, comprise semicircular shift fork body (1), installation shaft (2) and prong (3), three is connected as a single entity, described installation shaft (2) and prong (3) are arranged on outside the middle part of shift fork body (1), and prong (3) is towards left side, it is characterized in that: open the left end of crotch, right-hand member and middle part and be respectively provided with one piece of wear-resistant pad (4) adopting PA66 material to make in described shift fork body (1);
The upper and lower surface of the left and right end of described shift fork body (1) is respectively provided with at least one concave point (1a), the wear-resistant pad (4) being positioned at left and right end is injection-moulded in the inwall of shift fork body (1) termination, upper-end surface, lower end surface and concave point (1a) respectively, thus the inwall of the shift fork body (1) of corresponding position, upper-end surface, lower end surface are wrapped, and by the molded portion anticreep in concave point (1a);
The middle part of described shift fork body (1) has the intercommunicating pore (1b) of at least one up/down perforation, the wear-resistant pad (4) being positioned at middle part is injection-moulded in the inwall of shift fork body (1), upper-end surface, lower end surface and intercommunicating pore (1b), thus the inwall of the shift fork body (1) of corresponding position, upper-end surface, lower end surface are wrapped, and by the molded portion anticreep in intercommunicating pore (1b).
For convenience of manufacturing, and ensure anticreep effect, the concave point (1a) that the upper and lower surface of described shift fork body (1) termination is arranged is hemisphere, and the upper and lower surface of shift fork body (1) each termination is respectively provided with two, and the corresponding setting in upper and lower surface.
In addition, the intercommunicating pore (1b) that described shift fork body (1) middle part is offered is circular hole, totally two.
The beneficial effects of the utility model: structure is simple, it is ingenious to design, and by the wear-resistant pad of molding and forming, and jointly improves product strength and installation reliability in conjunction with disconnecting prevention structure; When after wear-resistant pad wearing and tearing, can Reusability after injection moulding again, shift fork main body can not be caused to scrap, greatly reduce user cost.
