DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] As attached Figure 1-4As shown, the utility model provides a car clutch release bearing, including a shaft rod 1, a release bearing protection device 2 is provided at the front end of the shaft rod 1, and the release bearing protection device 2 includes: a rotation stabilization component 21 and a heat dissipation protection component 22, and the heat dissipation protection component 22 is arranged on the side of the rotation stabilization component 21.
[0020] The rotation stabilization component 21 includes: an outer rotating shaft 211, a rotating steel ball group 212, a docking sealing groove 215, a heat dissipation frame 216, a docking inner rotating shaft 213 and a sealing limiting steel ring 214. The lower end of the sealing limiting steel ring 214 is installed on the outer wall of the upper end of the docking inner rotating shaft 213, and the outer wall of the upper end of the sealing limiting steel ring 214 can be rotatably installed in the docking sealing groove 215. The docking sealing groove 215 is opened at the lower end of the outer rotating shaft 211. Inside, the outer rotating shaft 211 and the sealing limiting steel ring 214 are each provided with two groups, and the two groups of sealing limiting steel rings 214 are adapted to the size of the outer rotating shaft 211. The rotating steel ball group 212 can be rotatably installed inside the outer rotating shaft 211, and the docking inner rotating shaft 213 can be rotatably installed inside the outer rotating shaft 211. The front end of the shaft 1 is installed on the side outer wall of the docking inner rotating shaft 213.
[0021] The heat dissipation protection component 22 includes: a heat-conducting aluminum plate 221, a heat dissipation ring 222 and a heat dissipation pipe 223. The lower end of the heat-conducting aluminum plate 221 is installed on the outer wall of the heat dissipation ring 222. There are multiple groups of heat-conducting aluminum plates 221, and the models of the multiple groups of heat-conducting aluminum plates 221 are similar. The inner wall of the heat dissipation ring 222 is installed on the outer wall of the front end of the shaft 1. There are multiple groups of heat dissipation pipes 223, and one end of the multiple groups of heat dissipation pipes 223 is respectively installed on the outer walls on both sides of the heat dissipation ring 222.
[0022] The specific implementation method is as follows: when using the present invention, due to long-term use and rotation, the internal friction of the outer rotating shaft 211 generates a lot of heat. When the rotating steel ball group 212 generates too much heat and cannot be discharged, it will affect the service life of the rotating steel ball group 212. The heat generated by the rotation of the rotating steel ball group 212 can be discharged through the heat dissipation frame 216 opened on the side, and the other part of the heat can be conducted and dissipated through the heat dissipation protection component 22 installed on the outer wall of the shaft rod 1. When the heat dissipation protection component 22 is performing conduction heat dissipation, the heat can be conducted out through the heat-conducting aluminum plate 221 arranged therein, and transferred to the inside of the heat dissipation ring 222, and then discharged by the heat dissipation discharge pipe 223 arranged inside the heat dissipation ring 222. When the heat-conducting aluminum plate 221 and the shaft rod 1 rotate synchronously, self-rotation heat dissipation can be performed, which further realizes the heat dissipation acceleration effect and greatly improves the heat dissipation effect of the entire component. The device conducts heat to the outer rotating shaft 211 by setting different heat dissipation modes, avoids the problem of the internal temperature of the outer rotating shaft 211 being too high and causing its service life to be shortened, and greatly improves the practicality and stability of the entire device.
[0023] Working principle of the present invention: When using the present invention, the internal friction of the outer rotating shaft 211 generates more heat due to long-term use and rotation. When the rotating steel ball group 212 generates too much heat and cannot be discharged, it will affect the service life of the rotating steel ball group 212. The heat generated by the rotation of the rotating steel ball group 212 can be discharged through the heat dissipation frame 216 opened on the side, and the other part of the heat can be conducted and dissipated through the heat dissipation protection component 22 installed on the outer wall of the shaft 1. When the heat dissipation protection component 22 is performing conduction heat dissipation, the heat can be extracted through the heat-conducting aluminum plate 221 arranged therein, and transferred to the inside of the heat dissipation ring 222, and then discharged through the heat dissipation discharge pipe 223 arranged inside the heat dissipation ring 222. When the heat-conducting aluminum plate 221 and the shaft 1 rotate synchronously, self-rotation heat dissipation can be performed, further achieving the heat dissipation acceleration effect.
