Problems solved by technology

[0002] With the development of the automobile industry, especially the research and development of new energy-saving and environmentally friendly vehicles, it is a challenge and an opportunity for auto parts, especially for commercial vehicles. The weight of each part must be reduced. The company combines new materials and new With the application of technology, the transmission shift fork has been improved to meet the requirements of the automotive industry for spare parts; the place where the shift fork is most likely to wear is the part where the shift fork and the synchronizer sleeve contact, because the synchronizer sleeve rotates at a high speed. The fork does not turn, the fork is worn, or the strength is not enough, which may cause the gear to be out of place, and the gear will be dropped, or the fork will be broken

Embodiment Construction

[0013] In the figure: a new type of shift fork for commercial vehicles, including a shift fork head 5, a shift fork body 6, and a shift fork foot 7. There is a shift fork shaft installation hole 3 on the shift fork head 5, and a pressure sleeve is provided in the shift fork shaft installation hole 3. That is, the shift fork hole pressure bushing 7 is a double alloy bush, one at each end, the inner layer of the shift fork hole pressure bush 7 is a wear-reducing plastic layer, and the installation of the shift fork hole pressure bush 7 adopts a hydraulic numerical control press. The sleeve is convenient to measure the interference force, and the contact seal is used to prevent the bushing 7 from falling off the hole of the shift fork. There is a pair of friction pairs 8 at the contact point between the shift fork and the tooth sleeve. The surface of the friction pair 8 is an arc-shaped structure; There are two clamps inlaid on the aluminum alloy base of the fork: one is the shift...

Abstract

A new type of shift fork for commercial vehicles relates to a transmission accessory for commercial vehicles, in particular to a new type of aluminum alloy shift fork for commercial vehicles. The purpose is to provide a new type of shift fork for commercial vehicles, which can achieve smooth shifting, reduce noise, improve wear resistance, smooth shifting and fast response by improving the structure of the shifting fork. It includes the fork head, the fork body and the fork foot. The fork head is provided with a mounting hole for the fork shaft. One of each, the inner layer of the fork hole pressing bush is a wear-reducing plastic layer, and the friction coefficient is small.

Description

technical field [0001] The invention relates to an accessory for a commercial vehicle transmission, in particular to a novel aluminum alloy shift fork for a commercial vehicle. Background technique [0002] With the development of the automobile industry, especially the research and development of new energy-saving and environmentally friendly vehicles, it is a challenge and an opportunity for auto parts, especially for commercial vehicles. The weight of each part must be reduced. The company combines new materials and new With the application of technology, the transmission shift fork has been improved to meet the requirements of the automotive industry for spare parts; the place where the shift fork is most likely to wear is the part where the shift fork and the synchronizer sleeve contact, because the synchronizer sleeve rotates at a high speed. The fork does not turn, the fork is worn, or the strength is not enough, which may cause the gear to not hang in place, and the ...
