Embodiment Construction
[0011] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0012] Automatic gearbox shift fork with decoupling device, e.g. figure 1 As shown, it is characterized in that it includes a shift fork base 4, a shift fork shaft 1, a slider 2, an elastic pin 3, a cylindrical pin 5, a spring 7 and a cover plate 6, wherein the spring 7 is installed in the hole of the shift fork base 4, and the gap Cooperate, block with the cover plate 6, the cover plate 6 and the shift fork shaft 1 clearance fit, and the groove on the cover plate 6 defines the position by the cylindrical pin 5. The slider 2 is assembled on the shift fork shaft 1 through the elastic pin 3, and has an interference fit, which plays the role of limiting the position and transmitting the shifting force. The slider 2 and the cover plate 6 are respectively located at both ends of the shift fork base 4, so that the shift fork assembly is rigidly connected ...

Provided is an automatic gearbox gear-shifting fork with a decoupling device. The automatic gearbox gear-shifting fork is characterized by comprising a shifting fork base, a shifting fork shaft, a slide block, an elastic pin, a cylindrical pin, a spring and a cover plate, wherein the spring is installed in the hole of the shifting fork base and is blocked by the cover plate; the cover plate is matched with the shifting fork through a gap, and a groove on the cover plate can limit positions through the cylindrical pin; the slide block is assembled on the shifting fork shaft through the elastic pin in an interference fit mode, and is used for playing the roles of limiting and transferring a shift force; the slide block and the cover plate are positioned at the two ends of the shifting fork base respectively, so that the shifting fork is always rigidly connected when the gear is engaged in the forward gear direction, and when the reverse gear is engaged and jammed, the shifting pork plays a decoupling role. The automatic gearbox gear-shifting fork integrates the decoupling device as a whole, has a compact structure and high precision, and improves the safety reliability of the automatic gearbox with the P gear engaged. In addition, through the use of the standard components of the spring, the cylindrical pin and the elastic pin, the costs of manufacturing, procurement, logistics and assembly of the P gear are reduced.
Description
technical field [0001] The invention relates to a shift fork of an automatic gearbox, in particular to a shift fork of a stepped automatic gearbox driven by a shift hub. Background technique [0002] The main function of the gearbox shift fork is to drive the synchronizer gear sleeve to move during the shifting process of the automobile gearbox to achieve shifting. The present invention is based on the fact that the reverse gear and the parking gear are driven by the same shift hub. To realize the electronic parking function, the R gear must be shifted to the R gear when the P gear is engaged, and then the gear shift hub rotates at a certain angle to realize the electronic parking function. . If the R gear is stuck, the shift hub will not be able to continue to rotate, and cannot be engaged in the P gear. How to make the shift hub continue to rotate to realize the electronic parking function is a topic to be studied by the present invention when the R gear is stuck. ...
