Integrated type lightweight aluminum alloy shifting fork assembly suitable for DCT gearbox

Abstract

The invention provides an integrated type lightweight aluminum alloy shifting fork assembly suitable for a DCT gearbox. The integrated type lightweight aluminum alloy shifting fork assembly comprisesa shifting fork body, a signal magnet assembly and a neutral gear positioning block, wherein the shifting fork body comprises a shifting fork shaft as well as a first fork foot and a second fork footwhich are connected onto the shifting fork shaft; a protective structure is further arranged on the shifting fork shaft and / or the first fork foot and the second fork foot; a lug boss structure is further arranged on the shifting fork shaft; and the signal magnet assembly and the neutral gear positioning block are arranged on the lug buss structure. According to the integrated type lightweight aluminum alloy shifting fork assembly provided by the invention, the lug boss structure is arranged on the shifting fork body, so that the signal magnet assembly and the neutral gear positioning block are conveniently assembled and fixed, and therefore, supporting effect is achieved, and anti-rotating effect is further achieved. Meanwhile, the protective structure is further arranged on the shiftingfork body, and the protective structure can protect a stress position on the shifting fork body, so that loss of the shifting fork is relieved, and the service life of the shifting fork is prolonged.Besides, the integrated type lightweight aluminum alloy shifting fork assembly is further matched with a sampling position to perform an optimized design on the structure of a magnet cap, so that mounting and fixing of a magnet inside are facilitated.

Description

technical field [0001] The invention relates to the technical field of automobile transmission, in particular to an integrated lightweight aluminum alloy shift fork assembly suitable for DCT gearboxes. Background technique [0002] The shift fork is mainly used for gear shifting of the gearbox. It is a component on the gearbox of an automobile. Under the action of the driving mechanism, the middle transmission wheel is moved to change the input / output speed ratio. However, there are structural defects in the existing shift fork, mainly as follows: 1), the assembly of the opponent part of the shift fork body is inconvenient; 2), the shift fork body is worn out with use; 3), the magnet inside the magnetic assembly It is inconvenient to install and fix. Therefore, in view of the above problems, it is necessary to propose a further solution. Contents of the invention [0003] The present invention aims to provide an integrated lightweight aluminum alloy shift fork assembly s...
