Trailer device

Abstract

The invention provides a trailer device, and relates to the technical field of vehicles. The trailer device comprises a winding reel, a trailer rope wound on the winding reel, a first hook claw connected with the trailer rope, a driving mechanism driving the winding reel to rotate, a proximity switch and a second hook claw which is connected with the driving mechanism through the proximity switch, and the second hook claw makes elastic contact with the proximity switch. When the rescue vehicle begins to advance, the trailer rope is in a tightened state, the second hook claw is stretched to be away from the proximity switch, the proximity switch is in a closed state at the moment, if the rescue vehicle brakes or stops, the second hook claw is retracted towards one side of the proximity switch, the proximity switch is started, the driving mechanism is started, then the trailer rope on the winding reel is driven to wind, the tightening force of the trailer rope is improved, then the tensioning state of the trailer rope is kept, the situation that a flameout vehicle breaks away from or deviates from the original distance or backs up in the rescuing process is avoided, and the safety of the flameout vehicle is greatly guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a trailer device. Background technique [0002] Existing automobiles have a tow hook in front of the car. After the car loses power, it will be hung on the tow hook by a special trailer with a trailer arm to tow the trailer, which is called a rigid trailer. For convenience, a non-dedicated trailer is towed with a tow rope, which is called a soft trailer. [0003] When the trailer is in operation, it is impossible for the trailer to maintain a stable pulling force all the time. When the pulling force of the trailer increases, the pulling force is borne by the tow rope, and the towing rope remains tense. When the pulling force of the trailer decreases or brakes, the towed vehicle maintains its original inertia Moving forward, the tow rope cannot rigidly support the inertial forward force of the trailer like the trailer arm, and it will inevitably make the tow rope tend to relax. ...

AI Technical Summary

Problems solved by technology

[0003] When the trailer is in operation, it is impossible for the trailer to maintain a stable pulling force all the time. When the pulling force of the trailer increases, the pulling force is borne by the tow rope, and the towing rope remains tense. When the pulling force of the trailer decreases or brakes, the towed vehicle maintains its original inertia Moving forward, the tow rope cannot rigidly support the inertial forward force of the trailer like the trailer arm, and it will inevitably make the tow rope tend to relax. The deceleration status is consistent with the reduction of the trailer's pulling force, and the tow rope cannot be kept in the original stable tension state.
