Automobile speed change control mechanism

Abstract

The invention relates to an automobile speed change control mechanism. The automobile speed change control mechanism comprises an operation base and a control rod, wherein a gear limiting disc is arranged inside the operation base; a reverse gear groove and a plurality of forward gear grooves are formed in the gear limiting disc, the forward gear grooves communicates with one another through a horizontally-arranged forward guide groove, and a horizontally-arranged reverse gear guide groove is formed in the reverse gear groove; the control rod is inserted into the forward guide groove, and a guide block is arranged at the bottom of the control rod and comprises an upper guide block, a lower guide block, a telescopic rod and a compression spring; and when the compression spring is in a balanced state, the forward guide groove is matched with the guide block in a balanced state, when the compression spring is in a compressed state, the reverse gear guide groove is matched with the guide block in a compressed state, and the reverse gear guide groove is connected with the forward guide groove through a limiting groove. When the control rod is engaged into a reverse gear, the control rod needs to be compressed downwards until the telescopic rod is shortest, the guide block moves into the reverse gear groove after entering the reverse gear guide groove, and the control rod is prevented from being engaged into the reverse gear groove due to misoperation when located in the forward guide groove.

Description

technical field [0001] The invention relates to the technical field of automobile transmissions, in particular to an automobile transmission control mechanism. Background technique [0002] The transmission control mechanism is used to change the collocation of transmission gears to achieve gear shifting. Under the operation of the driver, the transmission control mechanism can quickly, accurately and reliably remove, engage in a certain gear or return to neutral. The existing The transmission control mechanism is easy to shake in the transmission, and the safety of the transmission cannot be guaranteed, and the driver is likely to mistakenly engage the reverse gear while driving, which increases the risk of driving, and does not allow the driver to determine the shift shaft when shifting gears. It is cumbersome to operate whether the switch is in place, so it is necessary to improve the structure of the transmission control mechanism. Contents of the invention [0003] T...
