Description

Technical Field

[0001] This utility model relates to the field of automotive rubber core technology, specifically a novel automotive torque rubber core. Background Technology

[0002] Torque cores are applied to both ends of the torsion bar of the Sinotruk chassis axle, serving to dampen shocks, guide and transmit force. Most torsion cores are made of metal ball pins and vulcanized rubber. However, during long-term use, the wear and tear between the external and internal structures of the torsion core varies. Replacing all of them would result in material waste and make it inconvenient to disassemble and replace the corresponding structure. To reduce material waste, it is necessary to achieve the corresponding guiding and force transmission coordination, facilitate assembly and installation, and reduce the impact of external environmental interference on the gaps. Utility Model Content

[0003] The purpose of this invention is to provide a novel automotive torque rubber core to solve the problems mentioned in the background art.

Each core shaft has a positioning hole at its outer end. A sealing gasket is provided near the outer end of the outer wall of each core shaft. A limiting ring is provided at the inner end of the outer wall of each core shaft. One core shaft has a connecting post at its inner end, with a first screw hole in which a first flat-head bolt is installed. The other core shaft has a connecting groove at its inner end, and a first countersunk hole communicating with the connecting groove is provided on the outer wall of its outer wall. Annular grooves are formed on the outer wall of each half-roller, and limit grooves are formed on the inner wall of each half-roller corresponding to the limit ring. A symmetrical insert block is formed on the outer wall of one half-roller, and a second screw hole is formed on each insert block. A second flat-head bolt is formed in the second screw hole. A slot is formed on the other half-roller corresponding to the insert block. A second countersunk hole communicating with the slot is formed on the outer wall of the half-roller. A rubber sleeve is fitted on the annular groove.

[0005] Furthermore, the sealing gasket is bonded and fixed to the rubber core shaft, and grooves are provided on the ends of the half rollers. The inner diameter of the grooves is adapted to the outer diameter of the sealing gaskets, and the outer ring of the sealing gaskets is tightly fitted to the inner wall of the grooves.

[0006] In this invention, the sealing gasket and the groove are inserted into each other to increase the sealing between the rubber core shaft and the half roller, and reduce the impact of dust particles and water droplets from the external environment entering the interior through the gaps at both ends of the half roller.

[0007] Specifically, the limiting ring and the rubber core shaft are integrally formed, and the outer diameter of the limiting ring is adapted to the inner diameter of the combination of the two limiting grooves.

[0008] In this invention, the limiting ring and the limiting groove are inserted together to restrict the position of the rubber core shaft in the half roller.

[0009] It should be noted that the connecting column and one of the rubber core shafts are integrally formed, the width of the outer wall of the connecting column is adapted to the width of the inner wall of the connecting groove, and the end of the first flat-head bolt passes through the first countersunk hole and is threadedly connected to the first screw hole.

[0010] In this invention, the connecting column and the connecting groove are inserted into each other, and the first flat-head bolt connects the two rubber core shafts, which increases the stability of the assembly. If the rubber core shaft is damaged, it is easy to disassemble and replace half of it, reducing material waste.

[0011] Furthermore, the outer diameter of the annular groove is adapted to the inner diameter of the rubber sleeve, and the inner surface of the rubber sleeve is bonded and fixed to the inner wall surface of the annular groove.

[0012] In this invention, a rubber sleeve is fitted onto the cylinder formed by the combination of two annular grooves to seal the gap connecting the outer walls of the two semi-rollers, thereby increasing the tightness of the assembly.

[0013] It is worth adding that the insert block and one of the half rollers are integrally formed, the width of the outer wall of the insert block is adapted to the width of the inner wall of the slot, and the end of the second flat-head bolt passes through the second countersunk hole and is threadedly connected to the second screw hole.

[0014] In this invention, the insert block and the slot are inserted into each other to achieve quick and corresponding combination and fixation of the two half-rollers, and the second flat-head bolt is connected to the second screw hole to achieve combination and fixation of the insert block and the slot, thereby fixing the position between the two half-rollers.

[0015] The positioning holes facilitate the connection of external screws through them to the corresponding automotive components, allowing for the assembly and connection of the rubber core shaft end with the corresponding automotive parts.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model sets two rubber core shafts, which are connected by a connecting post and a connecting groove, and are threadedly connected by a first flat-head screw and a first screw hole to achieve a fixed combination of the two rubber core shafts. The two rubber core shafts are connected by a limiting ring and a limiting groove on a half roller. The half roller is connected by a second flat-head bolt and a second screw hole to achieve a rotating combination of the two half rollers and the two rubber core shafts. After long-term use and wear, it is easy to disassemble and replace them individually, reducing the material waste caused by replacing them all.

[0017] 2. This utility model achieves a tight seal between the rubber core shaft and the ends of the two half-rollers by setting a sealing gasket that fits tightly with the groove on the outer end of the half-roller, thereby reducing the impact of dust particles and water droplets from the external environment entering the interior. The rubber sleeve is fitted onto the two annular grooves to seal the gap between the side walls of the two half-rollers, increasing the stability of the seal. Attached Figure Description
