Abstract

The invention discloses a hydraulic control system for reverse locks. The hydraulic control system is characterized in that one end of a normally open contact 2 on one side of a shift handle 1 is connected with a positive pole of a power supply 3, the other end of the normally open contact 2 is connected with a solenoid coil 6 and a motor oil pump 16, the solenoid coil 6 is connected to a speed sensor 4 through an electric control component 5, the upper end of a compression spring 8 fixed on a spring holder 7 is connected with the solenoid coil 6 fixed on an operating cylinder 21, the lower end of the compression spring 8 is connected with an armature 9 fixed on a one-way valve 10, and a check ring 11 is disposed in a groove on the inner wall of the operating cylinder 21. Under the action of hydraulic drive and the electric control component, operation is convenient for a driver and is safe and reliable.

Description

technical field [0001] The invention relates to a hydraulic control system of an automobile reverse gear lock, belonging to the field of operating mechanisms of automobile transmissions. Background technique [0002] When the car is moving, if the reverse gear is accidentally engaged, there will be a huge impact between the transmission gears, resulting in damage to the parts; when the car starts, if the reverse gear is mistakenly engaged, safety accidents will easily occur. In order to prevent mistakenly engaging the reverse gear, a reverse gear lock should be provided in the operating mechanism. [0003] In practical applications, the reverse gear lock devices are all mechanically operated. For example, the commonly used reverse gear lock device in the five-speed transmission, the reverse gear lock device is composed of the first block, the reverse lock pin and the spring in the reverse block, so when the driver wants to hang into the first gear or the reverse gear , the...
