Abstract
The invention discloses a shifting fork with tension spring reinforcing ribs. The shifting fork comprises a shifting fork handle base, shifting fork arms and shifting fork feet. An installation hole is formed in the center of the shifting fork handle base. The shifting arms are arranged at the two ends of the shifting fork handle base. The shifting fork feet are installed at the bottoms of the shifting fork arms. The two reinforcing ribs are arranged at the end, connected with each shifting fork arm, of the corresponding shifting fork foot. A tension spring is connected between the two reinforcing ribs on each shifting fork foot. In this way, the stabilization of a shifting fork body can be improved by mounting the tension spring reinforcing ribs, the condition that the shifting fork body is broken when bearing large stress is avoided, and the service life of the shifting fork is prolonged.
Description
Technical field
The present invention relates to shift fork field, particularly relate to a kind of shift fork installing draught spring stiffening rib.
Background technique
Shift fork is the control of clutch in engineering goods, such as end face is in conjunction with the structure of tooth, the structure of interior external tooth, all need to realize combining and being separated by its part of fork controls, be parts important on automobile gearbox, be connected with gear change hand lever, be positioned at handle, at its lower end, stirring middle change pulley, making input, output speed than changing.But traditional shift fork part shift fork arm when being subject to larger stress easily rupturing, lacking and protecting accordingly, reducing the working life of shift fork.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of shift fork installing draught spring stiffening rib, the stable degree of shift fork body can be increased by installing draught spring stiffening rib, avoiding the situation that shift fork body ruptures when being subject to larger stress, extending shift fork working life.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of shift fork installing draught spring stiffening rib, comprise shift fork handle set, shift fork arm and shift fork fork pin, described shift fork handle set central authorities offer mounting hole, described shift fork arm is located at described shift fork handle set two ends, install bottom described shift fork arm and be provided with described shift fork fork pin, described shift fork fork pin and described shift fork arm connecting end are provided with stiffening rib, described stiffening rib comprises two, is connected with draught spring body between described stiffening rib.
In a preferred embodiment of the present invention, described stiffening rib transverse horizontal embeds in described shift fork arm, and between described stiffening rib, relative level is arranged, and the vertical connection of described draught spring body is located between described stiffening rib.
In a preferred embodiment of the present invention, described shift fork handle set, described shift fork arm and described shift fork fork pin is integral type casting linkage structure.
In a preferred embodiment of the present invention, described draught spring body also embeds in described shift fork arm.
The invention has the beneficial effects as follows: the present invention can increase the stable degree of shift fork body by installing draught spring stiffening rib, avoid the situation that shift fork body ruptures when being subject to larger stress, extending shift fork working life.
