[0019] Figure 1 It is a sectional view schematic drawing of one embodiment of the utility model.
[0020] Figure 2 It is a schematic drawing of prior art. DETAILED DESCRIPTION
[0021] The utility model discloses a high -life balance pole connecting rod, adopt adjustable structure pressure tight dust cover, improve the leakproofness of dust cover, increase the life. Further illustrate the utility model in the embodiment, a kind of high -life balance pole connecting rod, including rotatable connection's crossbar 1 and connecting rod 2, the crossbar is equipped with mounting seat 11, the movable slot 12 is equipped in the mounting seat, the connecting rod of one end extends into the movable slot and is equipped with ball head 21, further include dust cover 3, the dust cover one end is connected with the outer wall of mounting seat, the other end is connected with the outer wall of connecting rod;Adjusting sleeve 4, height adjustable is installed on the connecting rod;The one end of dust cover and connecting rod connection is contacted with the lower end surface of adjusting sleeve.Adjusting sleeve height adjustable can compress dust cover to some extent, install more flexible, improve the leakproofness of dust cover, increase the life. This is often in the dust, sand splashing working condition under the operation of car, can effectively improve the life.
[0022] In the embodiment, as shown in the drawing, the movable slot is equipped with ball seat 121, the ball head is matched with the outer wall spherical surface of ball seat. Ball seat is equipped with ball socket, to put into rotation for ball head, it is prior art, no longer repeat.
[0023] In the embodiment, as shown in the drawing, the ball seat is made of metal powder smelting. Compared with traditional plastic ball seat, the metal ball seat smelted by powder has better friction and impact and fatigue resistance. In the process of vehicle driving, especially in the steering and suspension system, larger friction can provide better position holding capability, ensure that the vehicle can stably maintain the predetermined driving track under various road conditions, and enhance the accuracy and stability of control. At the same time, this also means that in the extreme driving conditions such as emergency braking or sharp turning, the response of the vehicle is more rapid and reliable, which significantly improves the safety of driving. The improvement of impact and fatigue resistance further prolongs the service life of the ball seat.
[0024] In the embodiment, as shown in the drawing, the adjusting sleeve is connected with the connecting rod through threads. It is convenient to disassemble, and it is also convenient to disassemble the dust cover.
[0025] In the embodiment, as shown in the figure, at least one corrugated section 31 is arranged on the dust cover. The structure of the dust cover is optimized. Compared with the traditional dust cover, the ductility of the double-layer dust cover is better, the dust cover cannot be forced to stretch when the ball pin swings greatly, the sealing part cannot be deformed to cause foreign matter to enter, and the service life of the connecting rod is greatly prolonged. In addition, compared with direct press fitting, the double clasp ring meets the demand of replacing the damaged dust cover under the premise of ensuring the sealing property.
[0026] In the embodiment, as shown in the figure, an oil nozzle 5 is arranged at the bottom of the mounting seat, a through hole 122 is arranged at the bottom of the ball seat, and the through hole is arranged opposite to the oil nozzle for passing grease through the contact with the ball head.
[0027] In the embodiment, as shown in the figure, a bushing 6 is arranged at one end of the cross rod, and an outer pipe 61 is arranged outside the bushing. The bushing with the outer pipe has the advantages of high strength, durability, stability and vibration resistance, is suitable for high load, high vibration or harsh environment, and can significantly improve the performance and reliability of equipment. Stronger load capacity: because the metal outer pipe is used, the overall strength of the bushing is significantly improved, and greater load and impact can be borne. Protect rubber and prolong service life: the rubber body is protected from excessive wear and tear, and the service life is prolonged. Better stability: the outer pipe provides rigid support to prevent the bushing from deforming or shifting during operation, and ensures long-term stability. Reduce vibration and noise: the outer pipe can effectively absorb and disperse vibration, reduce noise, and improve the smoothness and comfort of equipment operation. The bushing is clamped into the pipe.
[0028] In the embodiment, as shown in the figure, the outer pipe is integrally formed with the cross rod. Compared with welding, the integral forming has the following advantages: high structural strength: the welding quality is uncontrollable, if welding defects such as blowhole, slag inclusion, incomplete penetration, incomplete fusion, crack and the like occur, the strength of the connection part will not be enough, and finally the bushing will fall off.
[0029] In the embodiment, as shown in the figure, the oil nozzle is arranged at the center of the bottom of the mounting seat.
