Vehicle traction rod

Abstract

The invention relates to a vehicle traction rod which comprises a fixing rod, a first extensible rod and a second extensible rod. One end of the first extensible rod and one end of the fixing rod are in sleeved connection in an axially extensible manner, one end of the second extensible rod and the other end of the fixing rod are in sleeved connection in an axially extensible manner, an axial tension damping device is arranged between the first extensible rod and the fixing rod, an axial compression damping device is arranged between the second extensible rod and the fixing rod, and a hanging hook is arranged at the other end of each of the first extensible rod and the second extensible rod. In the process of traction, when slamming on the brake or abrupt acceleration occurs, due to the buffering effect of the axial tension damping device or the axial compression damping device, influences on a vehicle ahead can be greatly reduced, so that the advantage that conventional rigid traction rods can avoid tailgating is maintained, mental tension of a driver is relieved, the defect that inertia of a vehicle behind can cause great influences on the vehicle ahead when the conventional traction rods are used is overcome, and safety is improved.

Description

technical field [0001] The invention relates to a vehicle traction device, in particular to a vehicle traction bar. Background technique [0002] When the vehicle needs to be removed from the scene after losing power (such as a breakdown) for some reason, in the absence of a professional trailer, a normal vehicle is generally used to tow the faulty vehicle. Therefore, a connection between the two vehicles is required. the traction device. Existing traction devices include two types, one is flexible traction cables or traction belts, and flexible traction cables or traction belts are used for traction. In the faulty car, a driver is still required to control the direction, and at the same time, it is necessary to pay attention not to communicate with the vehicle. If the vehicle in front is too close to avoid rear-end collision, the driver needs to be highly nervous, easily fatigued, and the safety hazard is relatively large, but the tow rope or tow belt is more convenient to...

AI Technical Summary

Problems solved by technology

Existing traction devices include two types, one is flexible traction cables or traction belts, and flexible traction cables or traction belts are used for traction. The driver still needs to control the direction in the faulty car, and it is also necessary to pay attention to not being in contact with the vehicle at all times. If the vehicle in front is too close to avoid rear-end collision, the driver needs to be highly nervous, easily fatigued, and has a relatively large safety hazard, but the tow rope or tow belt is more convenient to carry; the other type is to use a rigid tow bar, with Hook, when using the tow bar for towing, the distance between the two vehicles can remain unchanged, and there is no need to worry about rear-end collisions. However, when sudden braking or sudden acceleration occurs, because the tow bar has no buffer function, the inertia of the car behind will affect the The vehicle in front has a greater impact, and there are also certain potential safety hazards
