Description
Technical Field
The utility model belongs to the technical field of trailers, and particularly relates to an electric control trailer device.
Background
The tractor pulls the trailer forward and steering through the traction device, namely the tractor provides forward power, running direction and braking signals for the trailer. There are two traction modes of the traction device, one is hard traction, which is the main traction mode at present, and the other is soft traction. The rigid triangle trailer frame or the trailer rod is used for the hard traction device, and the traction vehicle directly controls the braking and steering of the trailer through the traction device. The soft traction mode uses a soft connecting device such as a traction rope or a chain, and most of the braking and steering devices of the trailer in the soft traction mode adopt mechanical devices, and the mechanical devices of the trailer are controlled to change the braking state and steering angle of the trailer through the force applied to the trailer by the traction device and the direction of the force.
In the hard traction mode, the traction device needs to bear the force generated by acceleration, deceleration and steering of the system, and the force can be transmitted to the tractor through the traction device, so that the effect on the tractor is large. In the soft traction mode, when the trailer tractors forward, the change speed of the traction device force signal is higher. Because the steering and braking device of the trailer adopts mechanical transmission, the execution of the mechanical action requires a certain time, and the change of the braking and steering state is difficult to realize in a short time.
