Title:
HYDRAULIC SHOCK ABSORBER
Document Type and Number:
WIPO Patent Application WO/2021/212720
Kind Code:
A1
Abstract:
A hydraulic shock absorber, pertaining to the field of motorcycle accessories, and comprising a hydraulic cylinder (1). A position-limiting disc (2) is fixedly mounted on a surface of the hydraulic cylinder (1). A hydraulic rod (3) is slidably mounted in the hydraulic cylinder (1). A first sleeve (6) is fixedly mounted on a surface of a connecting disc (4). A second sleeve (10) is fixedly mounted on a surface of the hydraulic cylinder (1). A threaded groove (11) is provided on a surface of the second sleeve (10). Through slots (12) are symmetrically provided on the surface of the second sleeve (10). A front axle (13) is slidably mounted in the second sleeve (10). A spring (5) mounted between the position-limiting disc (2) and the connecting disc (4) improves a shock absorption effect of the shock absorber. Heat conduction blocks (7) arranged equidistantly on the surface of the hydraulic cylinder (1) quickly transfer heat to a heat dissipation cylinder (8), thereby accelerating heat dissipation of the shock absorber and extending a service life of the shock absorber. A threaded connection is used, such that an engagement plate (16) can be removed, thereby facilitating disassembly of the front axle (13) and eliminating the issue in which an entire structure employing a conventional fixed connection between the front axle of a motorcycle and the sleeve of the shock absorber needs to be removed when making repairs.
