Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and specifically relates to a shock-absorbing joint tie rod. Background Technology

[0002] Vibration damping joints and tie rods are common connecting components used in machinery and automotive industries. Their main functions are to transmit power, bear loads, and guide motion. At the connection between the joint and the tie rod assembly, vibration and noise are often generated due to motion friction and the influence of the external environment. At the same time, dust and dirt may also penetrate into the connection area, affecting the performance and lifespan of the component.

[0003] Traditional shock-absorbing joint rod designs often neglect the issues of shock absorption, sound insulation, and dust prevention at the connection points. This can lead to problems such as wear, loosening, and noise at the connection points during long-term use, and in severe cases, it can even affect the stability and safety of the entire system. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a shock-absorbing connector rod that dampens vibrations, reduces noise, and prevents dust at the connection between the connector and the tie rod assembly.

[0005] The objective of this utility model can be achieved through the following technical solution: A shock-absorbing joint pull rod includes a pull rod, a pull rod seat is sleeved on the right side of the pull rod, a connecting rod is connected through the left side of the pull rod, a hexagonal nut is provided on the left side of the pull rod, the hexagonal nut is threadedly connected to the connecting rod, a connecting sleeve is sleeved on the left side of the connecting sleeve, a connector is connected through the top left side of the connecting sleeve, a bottom cover is connected through the bottom left side of the connecting sleeve, a shock-absorbing sleeve is sleeved on the bottom of the connector, a dust cover is sleeved on the surface of the connector, a support sleeve is sleeved outside the dust cover, a first rubber sleeve is sleeved on the left side of the connecting rod, a support tube is sleeved outside the first rubber sleeve, a support block is fixedly connected to the left side of the connecting rod, a second rubber sleeve is sleeved on the left side of the support block, the right side of the support tube is fastened to the connecting sleeve through a convex ring, and the right side of the connecting sleeve is riveted to the first rubber sleeve through a bent portion.

[0006] This vibration-damping joint rod uses a first rubber sleeve to buffer and support the upper, lower, front, and rear sides of the connecting rod, greatly reducing the vertical and horizontal vibration amplitude of the connecting rod. A second rubber sleeve provides lateral buffer and support for the support block and connecting rod, significantly reducing their lateral vibration amplitude. Both the first and second rubber sleeves have good elasticity and sound insulation properties, effectively absorbing and eliminating vibration, reducing noise transmission, and extending the service life of the joint rod. A support tube confines the support block to the inner wall of the connecting sleeve, ensuring a stable connection and preventing it from falling off.

[0007] This shock-absorbing joint rod incorporates a shock-absorbing sleeve to dampen the connection between the joint and the connecting sleeve. The shock-absorbing sleeve has excellent elasticity and damping properties, effectively absorbing and buffering vibration energy, reducing the vibration amplitude and frequency of the connection, and minimizing noise transmission. A hexagonal nut facilitates connection with the connecting rod. The combination of a dustproof sleeve, support sleeve, connecting sleeve, and joint seals the connection between the joint and the connecting sleeve, effectively preventing dust, dirt, and impurities from entering the connection and extending the service life of the joint rod.

[0008] In the aforementioned shock-absorbing joint rod, the surface of the dust cover is provided with an annular groove, and a fixing ring is fitted inside the annular groove. By providing the annular groove, the installation of the fixing ring is facilitated. By providing the fixing ring, the top of the dust cover can be locked and sealed, thereby improving the stability of the dust cover installation.

[0009] In the aforementioned shock-absorbing joint rod, a connecting screw hole is provided at the top of the joint, and a support sleeve is fitted onto the surface of the joint. The connecting screw hole facilitates connection with external connectors, and the support sleeve provides support for the joint and dust protection.

[0010] In the aforementioned shock-absorbing joint tie rod, the bottom of the bottom cover is connected to an oil injection pipe, and the bottom of the oil injection pipe is threaded with a pipe cap. By setting the oil injection pipe, it is convenient to inject lubricating oil into the bottom of the joint through an oil injection device to lubricate it and facilitate the movement of the joint. By setting the pipe cap, the bottom of the oil injection pipe is sealed.

[0011] In the aforementioned shock-absorbing joint rod, a sealing cover is fitted on the top of the support sleeve, and a spring telescopic rod is connected to the bottom of the sealing cover via a pivot. A hanging ring is fixedly connected to the bottom of the spring telescopic rod, and a hook is fixedly connected to the surface of the support sleeve. The hook engages with the hanging ring. By setting the sealing cover, the top of the support sleeve can be sealed to prevent external dust from entering the inner cavity of the support sleeve. By setting the spring telescopic rod, hanging ring, and hook, the sealing cover can be locked and fixed, improving the stability of the sealing cover and facilitating its removal.

[0012] Compared with existing technologies, the advantages of this shock-absorbing joint rod are: it can effectively absorb and buffer the vibration energy at the connection between the joint and the rod assembly, reduce the vibration amplitude and frequency of the connection, reduce noise transmission, effectively prevent dust, dirt and impurities from entering the connection, extend the service life of the joint rod, and provide effective buffer support at the connection between the connecting rod and the connecting sleeve in terms of vertical, horizontal and vertical, front and back and left and right, which greatly reduces the vibration amplitude of the connecting rod and reduces the noise generated by vibration at the connection.
