Outer barrel structure of magneto-rheological shock absorber

Abstract

The invention discloses an outer barrel structure of a magneto-rheological shock absorber. The outer barrel structure comprises an outer barrel body. A spring tray used for supporting and limiting a damping spring, a stabilizer support and an oil pipe fixing support used for fixing an oil pipe are arranged at the outer portion of the outer barrel body. The spring tray is arranged at the front portion of the outer barrel body, the stabilizer support is arranged at the middle portion of the outer barrel body, and the oil pipe fixing support is arranged at the rear portion of the outer barrel body. A piston rod fixing support used for fixing a piston rod is arranged inside the outer barrel body, and arranged at the rear end of the outer barrel body. A bottom cover is arranged at the rear end of the piston rod fixing support. A center hole is formed in the middle portion of the bottom cover, and a signal line of the shock absorber can penetrate out of the center hole. The provided outer barrel structure of the magneto-rheological shock absorber has the beneficial effects of being simple, low in manufacturing cost, good in installing and fixing effect and the like.

Description

technical field [0001] The invention relates to a shock absorber component, in particular to an outer cylinder structure of a magneto-rheological shock absorber. Background technique [0002] At present, traditional passive suspension shock absorbers are widely used in domestic automobiles. The damping coefficient and spring stiffness of this shock absorber are fixed and cannot play a good damping effect; while active suspensions can theoretically obtain An ideal vibration isolation system achieves the ideal suspension control goal, but it consumes a lot of energy, costs high, and has a complex structure; the cylindrical magneto-rheological shock absorber in the semi-active suspension effectively solves the problem of passive suspension. The contradiction between comfort and stability, while the control effect is also close to the performance of active suspension, and the structure is simple, the price is relatively cheap, and it does not need to provide additional energy an...

[0002] At present, the traditional passive suspension shock absorber is widely used in domestic automobiles. The damping coefficient and spring stiffness of this shock absorber are fixed and cannot play a good damping effect; while the active suspension can theoretically obtain An ideal vibration isolation system achieves the ideal suspension control goal, but it consumes a lot of energy, costs high, and has a complex structure; the cylindrical magneto-rheological shock absorber in the semi-active suspension effectively solves the problem of passive suspension. The contradiction between comfort and stability, and the control effect is also close to the performance of active suspension, and the structure is simple, the price is relatively cheap, and it does not need to provide additional energy and can generate a variety of damping forces. Better balance of riding comfort and handling stability
