Abstract
The utility model discloses a kind of automobile two stage impact damper, comprise oil hydraulic cylinder, and be arranged on the piston rod in oil hydraulic cylinder, the effect end of described piston rod extends to the outside of described oil hydraulic cylinder, and be welded with a columnar fixed block in this end, and being fixed with secondary dampening assembly by this fixed block, described secondary dampening assembly comprises shell, decoupling rod and capping; This device can carry out double absorption to the suffered vibratory forces of car body, greatly reduces the impact that road bump causes car body, improves the ride quality of vehicle.
Description
Technical field
The utility model relates to a kind of automobile two stage impact damper.
Background technique
Leaf spring 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 leaf spring are connected with car body crossbeam with hanger by pin conventionally.Leaf spring can delay and closes and absorb the shock and vibration that are subject in Vehicle Driving Cycle.
When the larger weight of automobile carrying, while travelling on the severe road surface of road conditions, leaf spring can be subject to excess impact, make axletree strike car bottom, and leaf spring can be subject to due to repeated stock, easily there is fatigue fracture at the two ends of spring and the joint in compartment, vehicle safety is caused to harmful effect.
For the foregoing reasons, simply leaf spring cannot meet use needs.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of automobile two stage impact damper, and this device can carry out double absorption to the suffered vibratory forces of car body, greatly reduces the impact that road bump causes car body, improves the ride quality of vehicle.
For addressing the above problem, the utility model adopts following technological scheme:
A kind of automobile two stage impact damper, comprise oil hydraulic cylinder, and be arranged on the piston rod in oil hydraulic cylinder, the effect end of described piston rod extends to the outside of described oil hydraulic cylinder, and be welded with a columnar fixed block in this end, and be fixed with secondary dampening assembly by this fixed block, described secondary dampening assembly comprises shell and decoupling rod, described shell has a stair-stepping through hole, described decoupling rod assigns in described through hole, the two ends of described decoupling rod all extend to housing exterior, on the ladder surface of described through hole, be positioned with a damping spring, on the outer bar wall of described decoupling rod, be arranged with positioning ring, the upper-end surface of described positioning ring and described damping spring offsets, between the hole wall of the smaller diameter end of described decoupling rod and described through hole, be provided with a dust ring, the outer installment of described shell has retainer ring, between described retainer ring and described fixed block, be fastened with several screws.
As preferred technological scheme, the lower end surface of described fixed block has the cone angle of-30 °～-60 °, and the top of described retainer ring has the taper hole with the identical tapering of this cone angle.
As preferred technological scheme, described decoupling rod is solid rod member.
As preferred technological scheme, the top of described shell is provided with capping, and the shaft core position place of described capping is provided with the first through hole that a described decoupling rod of confession passes.
As preferred technological scheme, between the outer bar wall of described the first through hole hole wall and described decoupling rod, there is the gap of 0.1mm～0.35mm.
The beneficial effects of the utility model are: by set oil hydraulic cylinder and secondary dampening assembly, make this device to carry out double absorption to the suffered vibratory forces of car body, greatly reduce the impact that road bump causes car body, improve the ride quality of vehicle, the working life of this device is comparatively lasting simultaneously, maintenance cost is comparatively cheap, is applicable to promoting the use of.
