Shift handling mechanism with clearance automatic compensating device

Abstract

The invention relates to a shift handling mechanism with a clearance automatic compensating device. The mechanism comprises a supporting plate, a fixing cover, a small dust-proof cover, a joint bearing, a shift shaft, a locking flange nut, a shift rod assembly and a bracket assembly, wherein the lower end of the fixing cover is connected with the supporting plate; the small dust-proof cover is connected with the upper end of the fixing cover; the joint bearing, the shift shaft, the locking flange nut, the shift shaft assembly and the bracket assembly are positioned in the small dust-proof cover and the fixing cover; and deformation buffering mechanisms are arranged outside the small dust-proof cover and the fixing cover. The shift handling mechanism with the clearance automatic compensating device provided by the invention has the benefits that the shift handling mechanism with a clearance automatic compensating device can adapt to the large amplitude vibration of a four-point suspension cab, through the adoption of the technical scheme, a hard bar handling device can be adopted for the speed changer, thereby solving the problem that hard bar handling cannot be carried out due to the large amplitude vibration of the cab, and further improving the comfortableness of the whole vehicle and bringing safety and comfort to drivers and passengers.

Description

technical field [0001] The invention relates to a shifting operation mechanism with an automatic clearance compensation device. Background technique [0002] In plateau or cold areas, freezing rain often occurs. At this time, if the transmission is operated with a flexible shaft, once the freezing rain hits the push-pull rod of the flexible shaft, it is easy to freeze the push-pull rod of the flexible shaft and the guide pipe, making it difficult to operate. Seriously affect driving safety, and the flexible shaft itself has poor cold resistance, and the bushing and protective tube of the plastic structure are easy to be hard and brittle in high cold, which affects the comfort of shifting gears and the service life of the flexible shaft. On the other hand, as people have higher and higher requirements for cab comfort, four-point suspension cabs have become more and more mainstream in the market. How to adapt to the large vibration of four-point suspension cabs has become a di...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a shift control mechanism with a gap automatic compensation device that can adapt to the large vibration of the four-point suspension cab. Adopting this technical scheme, the transmission can use a hard rod control device, thereby solving the problem caused by the cab The hard rod control cannot be arranged due to the large jump, so as to improve the comfort of the vehicle and bring safety and comfort to the drivers and passengers
