What is the function of the transmission interlock device?

[StCameron]

1. The function of the transmission interlock device: To prevent the occurrence of automatic gear shifting or gear disengagement during vehicle movement, where gear disengagement refers to the gear shifting back to neutral. 2. Automotive transmission: It is a set of speed-changing devices used to coordinate the engine speed with the actual driving speed of the wheels, aiming to achieve the optimal performance of the engine. 3. Working principle: The self-locking device consists of a self-locking steel ball and a self-locking spring. The upper surface of each shift fork shaft has three grooves distributed along the axial direction. When any shift fork shaft, together with the shift fork, moves axially to the neutral position or a working position, one of the grooves will align with the self-locking steel ball. Under the pressure of the spring, the steel ball embeds into the groove, fixing the axial position of the shift fork shaft. Consequently, the shift fork, along with the sliding gear (or engaging sleeve), is also fixed and cannot disengage on its own.
