[0003] Existing shift actuators have the following defects: First, since the housing is provided with a motor, the rotational torque of the motor will be decomposed into component forces that keep the base and the cover away from each other. The looseness between the gaps will greatly reduce the sealing performance, which will cause the internal space of the shift actuator to be disturbed by external factors such as dust, and will also cause oil leakage and water ingress; The upper and lower cooperation between the seat and the cover is fixed. Once the base and the cover become loose, the internal components of the housing, especially the motor as the active part, will loosen, which will lead to a large gap in the cooperation between the various components. error, eventually leading to serious damage to the shift actuator

The invention discloses a sealing structure of a shift actuator, comprising: a cover body; a base detachably connected with the cover body, a sealed space is formed between the base body and the cover body; the sealing A motor is arranged in the space, and the motor has a rotating shaft; the side of the base facing the cover is provided with a first fixing column and a second fixing column, and the first fixing column and the second fixing column are close to each other. One end of the cover body is provided with an arc surface that fits with the outer peripheral wall of the rotating shaft; the side of the cover body facing the base is provided with a first elastic member and a second elastic member. In this application, the first elastic member and the second elastic member are provided. When assembling and working, the first elastic member and the second elastic member respectively press the two ends of the rotating shaft, so that the connection between the base and the cover will not be damaged. They are subject to the force of separation from each other, so as to enhance the connection strength and sealing performance between the cover and the base.
Description
technical field [0001] The invention relates to the technical field of automobile transmission, in particular to a sealing structure of a shift actuator. Background technique [0002] The shift actuator is an important part of the automobile transmission system, and its housing generally includes a cover and a base, both of which are fixed by bolts or other means. [0003] Existing shift actuators have the following defects: First, since the housing is provided with a motor, the rotational torque of the motor will be decomposed into component forces that keep the base and the cover away from each other. The looseness between the gaps will greatly reduce the sealing performance, which will cause the internal space of the shift actuator to be disturbed by external factors such as dust, and will also cause oil leakage and water ingress; The upper and lower cooperation between the seat and the cover is fixed. Once the base and the cover become loose, the internal components of ...
