Abstract

The invention provides a double-cylinder active shock absorber. The other end of a compression valve component (9) at the tail of a round cylinder is communicated with a one-way valve (11) by virtue of an oil pipe; the one-way valve (11) is connected with an oil passage (5) in the round cylinder by virtue of a connecting oil pipe (12) which penetrates through an electromagnetic valve component (13); the periphery in the round cylinder is provided with a piston rod II (3); the middle of the periphery of the piston rod II (3) is provided with a dust-proof component (6); the lower part of the periphery of the piston rod II (3) is provided with a spring (7); the tail of the periphery of the piston rod II (3) is provided with a movable piston (10); the piston rod II (3) is connected to a movable piston (10); the spring (7) is arranged between the dust-proof component (6) and the movable piston (10). The double-cylinder active shock absorber is good in creation comfortability and good in 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 active 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 gives a sense of heartbeat acceleration, and speed of 60 / km / h is out of control (when turning the steering wheel when cornering, the tires will generate a slip angle and then generate a steering force, which acts on the rolling center and ...
