Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a rubber sealing cover with flame retardant effect. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. During the installation and use of the car steering gear, a rubber sealing cover is needed to seal the car steering gear to prevent dust and water from entering the steering gear and causing damage.

[0003] At present, a Chinese utility model with the announcement number of CN210769902U discloses a telescopic rubber sealing cover. This utility model relates to a telescopic rubber sealing cover, including a bellows-type cover body, wherein the axial ends of the cover body are respectively provided with a first port for installation with a universal joint and a second port for installation with a transmission shaft, and the cover body is provided with a sliding sleeve for axial sliding along the transmission shaft on the side of the second port, and the inner periphery of the sliding sleeve is provided with a sealing fitting surface that is matched with the outer peripheral shape and size of the transmission shaft. By adopting the above scheme, a telescopic rubber sealing cover is provided, which can realize the axial sliding of the cover body along the transmission shaft through the sliding sleeve, so that the cover body will not be damaged when the transmission shaft slides and the universal joint rotates. In addition, the setting of the sealing fitting surface, on the premise of realizing the sealing effect, realizes the disassembly and assembly of the sliding sleeve, so that the installation and disassembly of the sealing cover is convenient, and no redundant installation parts are required, so that the adaptability of the sealing cover is stronger.

[0004] When the existing rubber sealing cover is installed on the outside of the automobile transmission shaft for sealing, the rubber sealing cover is thermoplastically molded from general rubber material, and the general rubber material is not flame retardant after being heated.

Therefore, a rubber sealing cover with flame retardant effect is proposed to solve the above-mentioned problems. Utility Model Content
