Abstract

A double-cylinder shock absorber is characterized in that a piston rod (2) penetrates through a sealing assembly (1), a one-way valve (6) is mounted at one end of the piston rod (2), one end of a piston (7) is mounted at the end of the piston rod (2) and on the periphery of the one-way valve (6), an inner cylinder (5) is arranged at the end of the piston rod (2) and on the peripheries of the one-way valve (6) and the piston (7), a middle cylinder (4) is arranged on the periphery of the inner cylinder (5), a casing (3) is arranged on the periphery of the middle cylinder (4), and a valve seat (8), a shuttle valve (9), a compression valve assembly (10) and a rubber bushing assembly (11) are sequentially arranged at the other end of the piston (7). The double-cylinder shock absorber has good creative comfort and good turning performance.

Description

technical field [0001] The invention relates to a shock absorber installed on the chassis of a car, an suv off-road vehicle, and a van, in particular to a double-cylinder shock absorber. technical background [0002] As the automobile age develops and progresses, so does the driving of vehicles. The requirements for ride comfort and safety performance are getting higher and higher. [0003] At the end of September 2014, CCTV 13 broadcasted a travel safety program. A traffic police brigade and traffic safety experts were organized. Choose representative national roads and bends between provincial roads. A cornering experiment was done with a mid-to-high-end car. It is concluded that cornering at a speed of 40 / km / h is safe, 50 / km / h has the feeling of heartbeat acceleration, and 60 / km / h is out of control (turning the steering wheel when cornering, the tires will generate a slip angle and then generate steering force, which acts on the rolling center and center of gravity, ...
