Damper provided with floating piston

Abstract

The invention provides a damper provided with a floating piston. The damper comprises a piston rod, a guide sleeve, an oil seal, a steel pipe and a rear end socket. The guide sleeve is fixedly connected with the steel pipe. The rear end socket is arranged at the lower end of the steel pipe. The lower end of the piston rod penetrates through the guide sleeve and the oil seal from top to bottom to stretch into the steel pipe, and is fixedly provided with a piston. An inwards concave ring is formed in the middle of the steel pipe. The upper surface of the piston is lower than a plane where a curve is located, or the upper surface of the piston makes contact with the plane, wherein the curve is formed when an inwards protruding annular ring corresponding to the concave annular ring and the lower section of the steel pipe intersect with each other. The piston is provided with an oil guide hole communicating with the upper surface and the lower surface of the piston. The cylindrical-pipe-type floating piston is arranged in the position, above the concave annular ring, of the piston rod. The floating piston is in sealed connection with the inner surface of the steel pipe and the piston rod. A lower floating piston is arranged below the piston rod. The space between the floating piston and the lower floating piston is filled with an oil medium. The space between the floating piston and the oil seal is filled with a gas medium. One end of a gas guide hole of the rear end socket communicates with the space between the lower floating piston and the rear end socket. The other end of the gas guide hole communicates with the space between the floating piston and the oil seal.

Description

technical field [0001] The invention relates to the technical field of dampers, in particular to a damper with a floating piston. Background technique [0002] A damper or shock absorber is a device that uses damping properties to slow down mechanical vibration and dissipate kinetic energy. It is commonly used in the suspension system of cars and motorcycles, and some bicycles also have shock absorbers. Some skyscrapers also have dampers for earthquake resistance, such as Chinese Taipei 101, Kaohsiung 85 Building, etc. However, most of the current dampers are not provided with floating pistons, which affects the performance of the dampers. Contents of the invention [0003] The main inventive object of the present invention is to provide a damper with a floating piston. [0004] The technical solution used in the present invention is: a damper with a floating piston, including a piston rod, a guide sleeve, a skeleton oil seal, a steel pipe, and a rear head. The guide s...
