Embodiment Construction
[0030] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0031] like figure 1 , figure 2 and image 3 As shown, the car includes a shift fork shaft, and the device includes a gear selection shaft 1, a shift finger 2 and several fork frames 3, the fork frame 3 is connected with the shift fork shaft, and the fork frame 3 is selected along the fork frame. The axial direction of gear shaft 1 is arranged in parallel, and select shift shaft 1 is also worn on a select shift cover 6, and the select shift cover 6 is fixedly connected with the transmission housing. The upper part of the fork frame 3 is provided with a fork 31, and the shift finger 2 is fixedly connected to the selector shift shaft 1. A transmission structure that can only drive one of the fork frames 3 to swing when ...

The invention provides an automobile transmission gear interlocking device which belongs to the technical field of automobile transmissions, and is used for solving the technical problems of complicated structure, large occupation space, weakened shift shaft strength and the like of the conventional automobile transmission shift interlocking device. The automobile transmission shift interlocking device comprises a shift selection shaft, a shift finger and a plurality of fork frames, wherein the fork frames are connected with a shift shaft and are arranged along the axis direction of the shift selection shaft in parallel, fork openings are formed in the upper parts of the fork frames, the shift finger is fixedly connected to the shift selection shaft, each of the shift selection shaft and the shift finger penetrate into the fork openings, and a transmission structure which can only drive one fork frame to swing when the shift selection shaft rotates is arranged between the shift selection shaft and the fork frames. The automobile transmission gear interlocking device has the advantages of simple and compact interlocking mechanism and the like.
Description
technical field [0001] The invention belongs to the technical field of automobile transmissions, and relates to a gear interlocking device of an automobile transmission. Background technique [0002] In order to output the torque and speed suitable for each working condition to the driving wheels of the car, it is necessary to shift gears. Selecting different gears will output different speeds and torques to the drive wheels. If the car transmission selects two gears at the same time at a certain moment, the inside of the transmission will be stuck or even damaged. Therefore, there is an interlock device, whose function is to prevent the transmission from being engaged in two gears at the same time. The traditional interlock device is realized by using the structure in which the other two shift fork shafts are locked by steel balls when the middle shift fork shaft moves to engage the gear. interlocked. [0003] At present, most of the interlocking mechanisms have separate ...
