Traction connector with buffer

Abstract

The invention relates to a traction connector with a buffer, which comprises a traction side connection piece with a horizontal connection shaft hole and a vertical connection shaft hole, a fork joint piece including a pair of symmetrical arm parts and a base part, a connection shaft for coupling the traction side connection shaft between two arm parts of the fork joint piece, a transmission shaft fixed on the base part of the fork joint piece and a dragging side connection piece with a plurality of connection holes, wherein a through sliding sleeve cavity and a buffer cavity with an opening are formed on the connection piece; the connection piece is sleeved on the transmission shaft through the sliding sleeve cavity and axially limited by a locking piece; and a buffer spring is assembled on the transmission shaft which runs through the buffer cavity. The dragging side connection piece provided by the invention can move relatively and rotate 360 degrees on the transmission shaft and therefore can adapt to different various rugged and complex road conditions and can reduce the rigid impact during braking. The traction connector with the buffer has the characteristics of compact structure, high adaptability, high stability and long service life.

Description

technical field [0001] The invention relates to a connecting part of a vehicle, in particular to a traction connector with a buffer device suitable for use between a motor vehicle and a towed object. Background technique [0002] We know that the use of motor vehicles to tow other types of road vehicles has a wide range of applications. At present, the traction connectors between small vehicles and towed objects mostly adopt fork-type, hook-type or frame-type traction connection mechanisms. Rotate around a vertical axis so that the towed object can obtain an ideal turning radius; secondly, it can swing up and down around a horizontal axis so that the towed object can adapt to the fluctuation of the road surface during the journey. When encountering rough and complicated road conditions, especially when the height difference between the roads on both sides of the towed object is large, the towed object will deflect greatly. torque, it is easy to cause damage to the traction...

AI Technical Summary

Problems solved by technology

When encountering rough and complicated road conditions, especially when the height difference between the roads on both sides of the towed object is large, the towed object will deflect greatly. Torque, easy to cause damage to the traction connection mechanism

Although there is a ball-and-socket connector that can rotate in one direction, it is still not suitable for large-scale deflection of the dragged object due to the influence of the ball-joint journal.

In addition, when the above-mentioned traction connection mechanism is braked by the motor vehicle, other types of road vehicles towed will have a rigid impact on the traction connection mechanism due to inertia, and it is also easy to cause damage to the traction connection mechanism.
