Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a rubber sealing cover with a buffering 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 interior of the steering gear and causing damage to the steering gear.

[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 fixed on the outside of the transmission shaft for use, although the rubber sealing cover has a certain telescopic performance, the axial telescopic amount of the rubber sealing cover is small. If the rotation angle of the transmission shaft or the universal joint is too large, the stretching amplitude of the rubber sealing cover cannot be effectively supported and effectively buffered, which can easily cause the rubber sealing cover to wear, thereby reducing the service life of the rubber sealing cover. Therefore, a rubber sealing cover with a buffering effect is proposed to solve the above-mentioned problem. Utility Model Content

[0027] The utility model provides a rubber sealing cover with a buffering effect, which aims to solve the problem that when the rubber sealing cover is sleeved and fixed on the outer side of the transmission shaft for use, although the rubber sealing cover has a certain telescopic performance, the axial telescopic amount of the rubber sealing cover is small. If the rotation angle of the transmission shaft or the universal joint is too large, the stretching range of the rubber sealing cover cannot be effectively supported and effectively buffered, which easily causes the rubber sealing cover to wear, thereby reducing the service life of the rubber sealing cover.
