Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] refer to figure 2 , the shifting mechanism includes a self-locking device 1 driven by the shift lever 8, an elastic device 2 for locking the self-locking device, and a parking device driven by the self-locking device 1 to move along the guide device 5 when the P gear is engaged. Car bar 3, the parking pawl 6 that rotates around the rotating shaft under the action of the cone of the parking bar 3, and the parking ratchet 7 that links to each other with the transmission shaft of the gearbox.

[0039] refer to image 3 , Figure 4 and Figure 5 The self-locking device 1 includes a driving part 11 that cooperates with the shift shaft 8 and a locking part 12 that fits in the groove of the elastic device 2. The driving part 11 and the locking part 12 are paired by a first bolt 13 and a nut 14. It applies pressure to fit together. In orde...

Abstract

The invention relates to a gear shifting mechanism, in particular to an automatic transmission gear shifting mechanism. The technical problems that for an existing automatic transmission gear shiftingmechanism, the relative position between a self-locking device and an elastic device cannot be adjusted, so that the requirements on machining precision and installing precision of parts are high, and the production cost of products is high are solved. The automatic transmission gear shifting mechanism comprises a self-locking device, an elastic device, a parking rod, a guide device, a parking pawl and a parking ratchet wheel, wherein the self-locking device is a split piece and comprises a driving component and a locking component, a first through hole is formed in the driving component, a first kidney-shaped hole is formed in the locking component, and a first bolt sequentially penetrates through the first through hole and the first kidney-shaped hole to be connected with a nut; the elastic device comprises an elastic element and a gasket, a second kidney-shaped hole is formed in the elastic element, and a second through hole is formed in the gasket; and a second bolt sequentially penetrates through the second waist-shaped hole and the second through hole to be connected to the shell, and an adjusting pad is arranged between the gasket and the shell.

Description

technical field [0001] The invention relates to a shifting mechanism, in particular to an automatic transmission shifting mechanism. Background technique [0002] With the development and progress of the automobile industry, automobiles equipped with automatic transmissions are welcomed by more and more people because of their good comfort and ease of driving. The automatic transmission is equipped with a shifting mechanism for realizing P gear, R gear, N gear, D gear, S gear and other gear positions. After each gear shift is completed, the gear position needs to be locked by a self-locking device to prevent the car from being damaged by the outside world. Affected by the wrong gear switch. [0003] like figure 1 As shown, the existing automatic transmission shift mechanism includes a self-locking device 01, an elastic device 02, a parking lever 03, a guiding device 05, a parking pawl 06, and a parking ratchet 07. When shifting gears, the shift shaft 08 drives the self-lo...
