Description
Technical field
The utility model relates to a kind of improved type automobile absorber.
Background technique
Vibration damper is most widely used a kind of elastic element in automotive suspension, and it is the elastic beam being combined by some alloy spring sheets, and vehicle frame and axletree are flexibly coupled together.The two ends of vibration damper are connected with car body crossbeam with hanger by pin conventionally.Vibration damper can delay and closes and absorb the shock and vibration that are subject in Vehicle Driving Cycle.
But vibration damper of the prior art is simple hydraulic shock-absorption or spring shock absorption mostly, the working life of hydraulic shock-absorption is comparatively lasting, but its concussion sense reflection is poor, therefore shock resistance is poor, the seismaesthesia reflection of spring shock absorption is comparatively sensitive, but its bearing capacity is poor,, easily damage when larger when stressed.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of improved type automobile absorber, and the bearing capacity of this device is stronger, and working life is comparatively lasting.
For addressing the above problem, the utility model adopts following technological scheme:
A kind of improved type automobile absorber, comprise outer cylinder body, inner cylinder body, oil hydraulic cylinder, piston rod, decoupling rod, main damping spring, secondary damping spring and retainer, described inner cylinder body is arranged on the inside of outer cylinder body, and between outer cylinder body and described inner cylinder body, be provided with the cavity for running of hydraulic power oil, described oil hydraulic cylinder is arranged on the inner top of inner cylinder body, and described oil hydraulic cylinder communicates with described cavity, described piston rod is arranged in oil hydraulic cylinder, and the effect end of piston rod extends to oil hydraulic cylinder outside, described decoupling rod and piston rod coaxially arrange, described retainer is threaded and the effect end of described piston rod, described decoupling rod top is set in this retainer, and there is gap between the effect end of the top of described decoupling rod and piston rod, described secondary damping spring is arranged on this gap location, on the outer ring of described decoupling rod, be arranged with a positioning ring, described main damping spring is arranged between this positioning ring and described inner cylinder body inner bottom part, described main damping spring is set on decoupling rod outer ring.
As preferred technological scheme, the diameter of described main damping spring is greater than the diameter of described secondary damping spring.
As preferred technological scheme, when described secondary damping spring is unfolded to limit position, described decoupling rod is set in retainer.
As preferred technological scheme, the inner bottom part of described inner cylinder body is provided with a packing ring, and the outer wall of described packing ring and decoupling rod fits, and the lower end surface of described main damping spring and this packing ring offset.
As preferred technological scheme, described packing ring is that rubber is made, and described packing ring is frustoconic shape, and its large end face is relative with described main damping spring.
The beneficial effects of the utility model are: when automobile running is on road surface slightly when irregular location, just can absorb the seismaesthesia on road surface by main damping spring, when automobile running is during to the location of hollow comparatively, absorb seismaesthesia by main damping spring, in the time that main damping spring is not enough to absorb seismaesthesia, decoupling rod arrives at piston rod place under the effect of seismaesthesia, absorb seismaesthesia by oil hydraulic cylinder, this device can improve working life greatly, and reduces road surface seismaesthesia, improves the comfort level of car steering.
