A steering tie rod with a composite constant pressure chamber and one-way oil delivery protection

Abstract

The invention discloses a steering transverse pull rod with a composite constant pressure cavity provided with a one-way oil conveying protection function. The steering transverse pull rod structurally comprises a ball head, a dustproof cover, a connecting screw seat, a regulator, a pull rod and a pull rod assembly, the ball head is perpendicular and fixed to the top of the connecting screw seat, moreover, the middle portion of the ball head and the middle portion of the connecting screw seat are protected by the dustproof cover, inner threads of the connecting screw seat are tightly attached to outer threads of the regulator on the left side of the pull rod, and the pull rod perpendicularly penetrates through the center of the pull rod assembly. In conclusion, according to the steering transverse pull rod, after improvement, an outer protective sleeve is detected through the balance pressure, and meanwhile, a one-way oil guide seat is supplemented internally so that in the processes of performing maintenance and running on a bumpy road surface, the situation that impurities enter an inner joint during stirring of the ball head can be avoided, and then the influence of the impurities on the operation flexibility is reduced.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to a steering tie rod with a composite constant pressure chamber and one-way oil delivery protection. Background technique [0002] The steering rod is an important part of the steering mechanism of the car. It plays the role of transmitting motion in the steering system and directly affects the stability of the car's handling. Most existing cars use hydraulic power assist to facilitate the driver's quick steering. However, due to road conditions The reason will have a certain impact on the tie rod at the bottom: [0003] Since the joints of the tie rods are ball joints, they are prone to wear when walking on potholed dirt roads, and in the case of a large displacement, once the external dust-proof ring is damaged, impurities will be caused in the vibration Entering the inside of the ball shaft, the steering will not be sensitive at this time, and there will be excessive wear on one side ...

[0002] The steering rod is an important part of the steering mechanism of the car. It plays the role of transmitting motion in the steering system and directly affects the stability of the car's handling. Most existing cars use hydraulic power assist to facilitate the driver's quick steering. However, due to road conditions The reason will have a certain impact on the tie rod at the bottom:

[0003] Since the joints of the tie rods are ball joints, they are prone to wear when walking on potholed dirt roads, and in the case of a large displacement, once the external dust-proof ring is damaged, impurities will be caused in the vibration Entering the inside of the ball shaft, the steering will not be sensitive at this time, and there will be excessive wear on one side of the tire when walking for a long time. When the external rubber ring is replaced, the internal impurities cannot be removed well.
