Abstract
The utility model belongs to the technical field of an appliance for automobile parts, and particularly relates to a shifting fork. The shifting fork comprises a body, wherein one side of the body is in a convex arc-shaped surface, an arc concave surface is formed in the middle of the front end of the body, and circular arc transition is performed between the arc concave surface and the front end of the body; the rear end of the body is connected with a cylinder, a through hole is formed in the axial direction of the cylinder, the outside part of the cylinder is connected with a connecting piece, and a clamping slot is formed in one side of the connecting piece. The shifting fork provided by the utility model is simple in structure, is capable of reducing the stress received by the shifting fork well, greatly enhancing the using strength, and prolonging the service life.
Description
Technical field
The utility model belongs to auto parts apparatus technical field, relates in particular to a kind of shift fork.
Background technique
Shift fork is the part belonging in auto parts and components, be mainly to promote sliding gear, have an annular groove shift fork just to ride in this annular groove on sliding gear, in the time that driver promotes speed change lever, speed change lever drives declutch shift shaft, declutch shift shaft drives shift fork, reaches gear shift thereby shift fork promotes again gear.Material nonhomogeneous hardness between shift fork and sliding gear is larger, long-time rubbing contact, and when poor in road conditions especially and Vehicular shift, shift fork driven gear, causes shift fork inordinate wear for a long time.The unreasonable design of shift fork also can make shift fork stressed unreasonable, and shift fork occurs crackle from stress raiser, and prolonged exercise can rupture.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of shift fork is provided, and its technological scheme is as follows:
A kind of shift fork, it is characterized in that, described shift fork comprises body, the side of body is evagination arc shaped surface, the centre of the front end of described body is circular arc concave surface, between described circular arc concave surface and the front end of body, be arc transition, the middle part of described circular arc concave surface is long strip arc-shaped recess portion, and the two ends of described circular arc concave surface are provided with shift fork head; The front of body is provided with hollow slot, and the front end of hollow slot is arc shaped surface, the arc shaped surface of the front end of described hollow slot and circular arc concave surface concentric; The rear end of described body is connected with cylindrical body, and arc transition between described cylindrical body and body described cylindrically offers through hole on axially, and described cylindrical lateral part is connected with link, and the sidepiece of described link offers draw-in groove.
The shift fork that the utility model provides, when in use, shift fork head contacts with the gear in gearbox.The cylindrical through hole of offering on is axially can be fixed on the axle of gearbox.And the link that cylindrical lateral part connects, the draw-in groove that the sidepiece of described link is offered, is used for connecting each shift fork, and each shift fork is connected as a body.
The beneficial effects of the utility model are:
The utility model is simple in structure, can be good at reducing the stress that shift fork is subject to, and can strengthen greatly working strength, increases working life.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Illustrate embodiment below in conjunction with Fig. 1:
A kind of shift fork, it is characterized in that, described shift fork comprises body 1, the side of body 1 is evagination arc shaped surface, the centre of the front end of described body 1 is circular arc concave surface 2, between described circular arc concave surface 2 and the front end of body 1, be arc transition, the middle part of described circular arc concave surface 2 is long strip arc-shaped recess portion 3, and the two ends of described circular arc concave surface 2 are provided with shift fork head 4; The front of body 1 is provided with hollow slot 5, and the front end of hollow slot 5 is arc shaped surface, the arc shaped surface of the front end of described hollow slot 5 and circular arc concave surface 2 concentrics; The rear end of described body 1 is connected with cylindrical body 6, arc transition between described cylindrical body 6 and body 1, in the axial direction of described cylindrical body 6, offer through hole 7, the lateral part of described cylindrical body 6 is connected with link 8, and the sidepiece of described link 8 offers draw-in groove 9.
The shift fork that the utility model provides, when in use, shift fork head contacts with the gear in gearbox.The cylindrical through hole of offering on is axially can be fixed on the axle of gearbox.And the link that cylindrical lateral part connects, the draw-in groove that the sidepiece of described link is offered, is used for connecting each shift fork, and each shift fork is connected as a body.
In the time that driver promotes speed change lever, speed change lever drives the axle of gearbox, and the axle of gearbox drives shift fork, reaches gear shift thereby shift fork promotes again gear.
