Abstract

The invention provides a lock-up structure of a follow-up bridge of a vehicle, a control method thereof and the vehicle. The lock-up structure comprises an air cylinder body, a piston and a gas storage device. The piston is connected to the air cylinder body and the follow-up bridge, separately, and the air cylinder body is connected to the gas storage device. The lock-up structure also comprisesa control valve which comprises an air inlet port, an air outlet port and an exhaust port. The exhaust port communicates to external environment, and the air inlet port communicates to the gas storagedevice. The control valve has a first state and a second state. In the first state, the air outlet end is opened, the air inlet port communicates to the air outlet port and the exhaust port is cut off; in the second state, the exhaust port is opened, the air outlet port communicates to the exhaust port and the air outlet port is cut off. According to the lock-up structure of the follow-up bridgeof the vehicle and the control method thereof, the working hour of the valve body is shortened and the service life of the valve body is prolonged by arranging the normally opened valve body. The lock-up structure is safe and reliable and low in cost and is suggested to be popularized and used on a large scale.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a locking structure of a vehicle tag axle, a control method thereof, and a vehicle. Background technique [0002] The follower bridge is a key component of the car, which is used to carry and connect the front and rear parts of the car. During the driving process of the car, if the follower bridge keeps moving freely, it will cause excessive wear of the car tires. Therefore, when the car is running at high speed , to lock the follower bridge. [0003] The locking cylinder of the tag axle is the executive component that keeps the tag axle in a straight line state after ventilation. It is used to lock the tag axle of the car. Its basic working principle is: after ventilation, the cylinder rod is pushed out to the limit position to lock the steering knuckle corner, keep the tires running in a straight line; after the exhaust, the cylinder is not limited, and the wheel turns ...
