Kingpin installation locking structure

Abstract

The invention discloses a kingpin installation locking structure. The structure comprises an I-beam, a kingpin and a steering knuckle. The steering knuckle comprises a top and a bottom, and steering knuckle through holes are respectively formed at the top and at the bottom. The I-beam is provided with an I-beam through hole. The I-beam is arranged between the top and the bottom of the steering knuckle. The kingpin penetrates through the steering knuckle through holes and the I-beam through hole, and the kingpin is rotatably matched with the I-beam. The kingpin is provided with a lubricating flow passage. The starting point of the lubricating flow passage is arranged at an end of the kingpin. The ending point of the lubricating flow passage is formed on the wall of the kingpin which is arranged inside the I-beam through hole. According to the kingpin installation locking structure, a groove is not provided with the I-beam, and therefore the strength of the I-beam is improved. The kingpin is provided with a lubricating flow passage therefore the smoothness of the rotation between the kingpin and the I-beam is ensured, meanwhile, the kingpin is fixed to the steering knuckle, the abrasion of the end cap and the block cap of the kingpin is prevented.

Description

technical field [0001] The invention relates to a vehicle structure, in particular to a kingpin installation and locking structure. Background technique [0002] see figure 1 , is a schematic diagram of the kingpin installation and locking structure in the prior art, which includes an I-beam 01 , a lock pin 02 , a steering knuckle 03 , a kingpin 04 and an end cover 05 . [0003] As we all know, the kingpin 04 is a component of the front axle, and its function is to fix the steering knuckle 03 and the I-beam 01 together, so that the steering knuckle 03 rotates around the end of the I-beam 01. Generally, the kingpin 04 passes through the steering knuckle 03 The upper and lower holes of the I-beam 01 and the fist hole of the I-beam 01, the side of the main pin hole on the I-beam 01 is provided with a lock pin 04, which is located at the fist part of the I-beam 01. [0004] The lock pin 04 is located at one end of the fist of the I-beam 01, and the force is not good. During th...

AI Technical Summary

Problems solved by technology

[0004] The lock pin 04 is located at one end of the fist of the I-beam 01, and the force is not good. During the load-bearing process, the lock pin 04 and the I-beam 01 are easy to wear and deform, which will cause vehicle brake vibration, brake deviation, etc. Phenomenon

The blocking cover 05 of the kingpin 04 is fixed together with the kingpin 04, and the kingpin 04 is fixed together with the I-beam 01, which causes relative movement between the steering knuckle 03 and the blocking cover 05 when the front axle turns, and the blocking cover The inside of 05 is a steel skeleton structure, and the outside is covered with rubber, which will cause wear on the rubber part of the plug 05, thus losing the sealing effect on the main pin 04
