Abstract

Provided is a gear locking device of a vehicle. The gear locking device of the vehicle comprises a gear-selecting operation valve, a forward gear clutch, a backward gear clutch, a hydraulic pump, a fuel tank, a first electromagnetic valve, a second electromagnetic valve, a first pressure sensor, a main controller, a second pressure sensor, a rotating speed sensor and an induction part. An execution opening A of the gear-selecting operation valve communicates with the first pressure sensor and an oil inlet of the first electromagnetic valve. An execution opening of the first electromagnetic valve communicates with the forward gear clutch. An execution opening B of the gear-selecting operation valve communicates with the second pressure sensor and an oil inlet of the second electromagnetic valve. An execution opening of the second electromagnetic valve communicates with the backward gear clutch. The first electromagnetic valve, the second electromagnetic valve, the first pressure sensor,the second pressure sensor and the rotating speed sensor are all in electric connection or wireless communication with the main controller. A gearbox is long in service lifetime and high in driving safety. A traffic accident is not likely to occur.

Description

technical field [0001] The invention relates to a vehicle, in particular to a gear locking device for the vehicle. Background technique [0002] After the vehicle is driven in forward gear, it is not allowed to directly switch from forward gear to reverse gear during the driving process of the vehicle; after the vehicle is driven in reverse gear, it is not allowed to directly switch from reverse gear to forward gear while the vehicle is running. It is because if this operation will cause the gears in the gearbox of the vehicle to wear or collapse, which will directly affect the service life of the gearbox of the vehicle, and will also reduce the safety of driving, and traffic accidents will easily occur. However, in practice, it often occurs that after the vehicle is driven in forward gear, the driver mistakenly engages in reverse gear during the running of the vehicle, or after the vehicle is driven in reverse gear, the driver mistakenly engages in forward gear during the r...
