Description

Technical Field

[0001] The utility model relates to the technical field of gear selection and shifting sensors, in particular to an easily disassembled fixing structure for a gear selection and shifting sensor of an automobile transmission. Background Art

[0002] Sensors are widely used in automobiles. Their main function is to convert non-electrical signals into electrical signals. They mainly include temperature sensors, pressure sensors, speed and position sensors, oxygen sensors, etc. According to their working principles, automobile sensors can be divided into: resistance, capacitance, inductance, voltage, Hall, photoelectric, grating, thermocouple, etc. Among them, resistance and Hall sensors are widely used due to their low cost and reliable operation.

[0003] In the related technology, a solution of an automobile transmission gear selection and shifting sensor device (Announcement No.: CN204420085U) was found through searching. When in use, two rotation angle sensors are installed on a bracket. The gear selection and shifting actions of the transmission shift rocker arm trigger the two sensors to generate signals respectively, which are transmitted to the electronic control unit. The device is reliable in operation, easy to manufacture and install, and has a compact overall appearance, which is easy to arrange on the transmission and has low cost.

[0004] However, since the gear selection sensor and the gear shift sensor are respectively fixedly connected to the bracket, during long-term use of the car, when the car is driving on the road, due to potholes and depressions, long-term bumps will damage the gear selection sensor and the gear shift sensor, and they need to be replaced. When the gear selection sensor and the gear shift sensor need to be removed, the gear selection sensor, the gear shift sensor and the bracket need to be replaced as a whole, which increases the cost of using the sensor, and further makes the replacement of the gear selection sensor and the gear shift sensor more cumbersome and inconvenient to operate. In view of this, we introduce a disassembly fixing structure for a car transmission gear selection and shift sensor. Utility Model Content
