During the running of the automobile, if the automobile runs on an uneven road or turns, the wheels on the left side and the right side are at different heights, so that the transverse rolling of the automobile body can be caused. In order to prevent the transverse side inclination of the automobile body and improve the smoothness and comfort of the automobile in the running process, a transverse stabilizer bar is arranged at the bottom of the automobile.
The stabilizer bar is a U-shaped torsion spring bar made of spring steel and is transversely arranged at the front end and the rear end of the bottom of the vehicle body. The middle part of the transverse stabilizer bar is hinged with the frame through a sleeve, and the two ends of the transverse stabilizer bar are connected with the lower supporting arms or the shock absorber sliding columns along the transverse left side and the transverse right side of the vehicle through a connecting rod assembly with a ball hinge. The main effect is that the roll elasticity is effectively ensured on the premise of not changing the elasticity in the vertical direction so as to improve the comfort of the vehicle.
At present, a connecting rod assembly mainly comprises a dustproof sleeve, a clamp spring, a ball pin, a bushing, a ball pin seat and a gland. The machining process of the ball pin seat comprises the following steps: preparing raw materials, performing cold extrusion molding, and turning. The assembly process of the connecting rod assembly comprises the following steps:
1. cleaning the ball head of the ball pin, and assembling the head of the ball pin in the bushing;
2. assembling a seal, assembling the ball pin and the bush into the ball pin base from the bottom of the ball pin base together, and installing a gland at the bottom of the ball pin base;
3. injecting grease into the inner cavity of the bushing from the neck part of the ball pin;
4. sleeving a dustproof sleeve on the rod part of the ball pin, wherein an upper lip of the dustproof sleeve is clamped with the rod part of the ball pin, and a lower lip of the dustproof sleeve is fixed in a clamping groove in the upper part of the outer peripheral wall of the ball pin seat by adopting a clamping spring;
5. and removing grease on the surface of the connecting rod assembly.
The above structure and process have the following disadvantages:
1. the ball pin seat has multiple processing procedures, lower production efficiency and higher cost;
2. during the assembly and sealing process, the gland is turned, rolled, pressed and fixed through the spigot edge of the ball pin seat, the gland can compress the bushing, and the bushing deforms microcosmically to hold the ball head tightly to generate torque. Due to the size deviation of the ball pin seat, the deformation of the bush is large, and finally, the moment difference value or the moment super difference at two ends of the connecting rod assembly is increased, so that the whole comfort is influenced or the connecting rod assembly is scrapped;
3. the ball pin base spigot edge is rolled to compress the gland so as to realize the sealing mode of the ball pin head, and the problems of low planeness of the gland, insufficient rolling of the ball pin base spigot edge and the like easily cause early failure of sealing and reduce the service life of a connecting rod assembly;
4. the lower lip of the dustproof sleeve realizes a fixed and sealed structure through the clamp spring, and an inner hole of the clamp spring needs to be enlarged in the assembling process, so that the clamp spring is easy to generate permanent deformation and the tightening force is reduced, a gap is generated between the lower lip of the dustproof sleeve and a clamping groove of the ball pin base, the early failure of sealing is finally caused, and the service life of a connecting rod assembly is reduced;
5. after the ball pin and the bush are assembled, the rod part of the ball pin is inserted into the inner hole from the bottom of the ball pin seat and then penetrates out of the top of the ball pin seat, and the ball pin is limited by space, so that the circular truncated cone of the rod part of the ball pin has small flat area, small contact area with a stabilizer bar, a swing arm and the like, and cannot provide enough friction force, and the connecting rod assembly cannot be assembled or disassembled;
6. the upper end face of the clamping groove part of the peripheral wall of the ball pin seat is easily contacted with the connecting rod, so that the swing range of the connecting rod assembly is narrow.
