Description

Technical Field

[0001] This utility model relates to the field of shift booster technology, specifically a shift booster activation device with positioning function. Background Technology

[0002] In existing manual transmission vehicles, the shift booster is an important component, helping drivers operate the shift lever more easily to change gears. Traditional shift boosters typically include a valve core switch that controls the pneumatic assistance, thus aiding the driver in shifting gears. However, existing shift booster valve core switch follow-up mechanisms have some shortcomings, affecting the accuracy and convenience of shifting.

[0003] Traditional gear shift boosters typically require an external gear positioning device, which not only increases system complexity but may also lead to inaccurate positioning and affect shift reliability. Due to the need for an external positioning device, traditional gear shift boosters have low system integration, which is not conducive to improving overall performance and reducing maintenance costs. Therefore, this utility model proposes a gear shift booster opening device with positioning function to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a shift booster activation device with positioning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shift booster opening device with positioning function, including a rotating arm, an output shaft, and a bracket. The rotating arm is provided with a first hole, a second hole, and a positioning part. An input shaft is provided in the first hole, and the second hole is used to install a pin connected to the bracket. The rotating arm and the bracket can rotate around a connecting shaft. The output shaft is connected to the bracket to form an integral driven structure. The output shaft is used to drive the gearbox to shift gears.

[0006] Preferably, the positioning part is configured as a positioning hole, which is used to install a gear positioning spring or a positioning pin.

[0007] Preferably, the positioning part is configured as a positioning groove, which is used for positioning in the neutral position.

[0008] Preferably, the input shaft and the rotating arm can be fixed by a connecting pin, which can be a cotter pin, a solid pin, or a screw.

[0009] Preferably, the bracket is provided with mounting hole one, mounting hole two, and adapter hole, and mounting hole one and mounting hole two are coaxially arranged.

[0010] Preferably, the central axis of the output shaft, mounting hole one, mounting hole two, and adapter hole are in the same plane, and the output shaft is located below mounting hole two.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When the input shaft rotates under force, the output shaft must simultaneously experience resistance in the opposite direction for the central axis of the adapter hole to shift. If there is no resistance in the opposite direction, the central axis of the adapter hole will not shift, thus effectively controlling the valve core switch of the shift booster. The positioning hole or positioning groove enables the installation of the gear positioning device, eliminating the need to install a separate gear positioning device outside the booster, thereby increasing the system's integration.
