Embodiment Construction

[0020] see figure 1 , The invention discloses an automobile control arm rotation and lubricating system. As shown in the figure: it includes a control arm 13. The control arm 13 cooperates with a pair of back-to-back single-row cone bearings 8. A pin shaft 10 passes through the middle of the single-row cone bearings 8 and is tightened with nuts 4; the pin shaft 10 is closed at both ends. , the inner cavity is divided into two sections by the piston assembly 5, a section of the inner cavity passing through the single-row cone bearing 8 is filled with a lubricating substance (such as: lithium-based grease), and a spring 2 is set in the other section of the inner cavity. When the control arm 13 is in motion, the lubricating substance is consumed, the spring 2 continues to bounce back against the piston assembly 5 and moves downward, and the lubricating substance in the cavity of the pin shaft 10 enters the cavity of the single-row tapered bearing 8 from the hole of the pin shaft ...

Abstract

The invention relates to a rotation and lubrication system for an automobile control arm. The rotation and lubrication system comprises the control arm. The control arm is matched with a pair of bearings, and a pin shaft penetrates through the portion between the bearings and is tensioned through a nut. The two ends of the pin shaft are closed, an inner cavity of the pin shaft is partitioned into two sections through a piston assembly, one section, penetrating through the bearings, of the inner cavity is filled with lubricating matter, and the other section of the inner cavity is internally provided with a spring. When the control arm moves, the lubricating matter is consumed, the spring continuously rebounds to jack the piston assembly to move downwards, and the lubricating matter in the cavity of the pin shaft enters inner cavities of the bearings from a hole of the pin shaft for lubrication. The purposes that the bearing capacity of the control arm is enhanced, the system is maintained (the lubricating matter is automatically added) in a free-of-charge mode, and the service life of the system is prolonged can be achieved.

Description

technical field [0001] The invention relates to an automobile control arm rotation and lubricating system. Background technique [0002] At present, the rotation mode of the control arm of the automobile suspension system is mainly based on rubber parts, and the torsion angle of the general rubber parts is less than 15°. However, the rotation angle of the automobile suspension system with a large stroke is about 30°, and the torsion angle of the current rubber parts cannot be realized, so a 360° rotation system structure must be adopted. The currently used 360° rotation system is a steel bushing rotation system. Its main problems are: [0003] 1. Refueling is required frequently, and maintenance is troublesome. [0004] 2. Steel bushing has small specific pressure and poor bearing capacity. [0005] 3. Steel bushing and pin shaft rotate to generate friction, and the service life is low. Contents of the invention [0006] In order to solve the above-mentioned defects, ...
