Abstract
The utility model relates to a vibration absorber with multi-level vibration reduction, which relates to a vehicle vibration absorber, belongs to a hydraulic vibration reduction device suitable for a joint part of a wheel and a vehicle body, such as a car, a truck and the like and suitable for other technical fields needing vibration reduction. The vibration absorber solves the problem that a known hydraulic vibration absorber is a single-level vibration absorber which can not initiatively reduce vibration, can not automatically balance according to different road conditions, enhances the bounce force of a vehicle body and causes the vehicle not to obtain vibration reduction protection. The technical scheme of the utility model is that the vibration absorber with multi-level vibration reduction consists of a big hydraulic vibration reduction oil cylinder and a small hydraulic vibration reduction oil cylinder, wherein the bottom of the big hydraulic vibration reduction oil cylinder is connected with the piston rod of the small hydraulic vibration reduction oil cylinder. In the utility model, the big hydraulic vibration reduction oil cylinder and the small hydraulic vibration reduction oil cylinder make complementation in time by means of liquid pressure and have the functions of automatic balancing according to different road conditions, automatic rigidity transformation and damp buffering. In addition, the utility model has simple and compact structure, small volume and low cost, is suitable for vibration reduction of vehicles and can be used for vibration reduction of other equipment.
Description
Technical field
The utility model relates to a kind of vehicle shock absorber, relates to a kind of hydraulic shock-absorbing device that is applicable to car, truck, minibus, minicar car body and wheel linking portion specifically, also goes for the technical field that other need vibration damping.
Background technique
Known vehicle shock absorber has dydraulic shock absorber; it is to do in oil cylinder by piston; following motion; promote in-oil cylinder hydraulic oil plays vibration damping under certain pressure effect; because this vibration damper is a kind of single-stage vibration damper; effect is not fine; again because itself design deficiency, can only passive vibration damping, and can not active damping; when vehicle driving arrives different road conditions; because the stroke of dydraulic shock absorber piston is long, and the hydraulic oil of vibration damper can not in time be covered, the rebounding force of himself will strengthen; vehicle is thrown a higher height; because the deadweight of vehicle body makes vehicle produce vibration, thereby make vehicle can not get the vibration damping protection.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, and propose a kind of simple in structure, can have the multistage vibration damping shock absorber for vehicle of automatic balance function with road condition change.
Technical solution of the present utility model is: multistage vibration damping vibration damper comprises a liquid-springing oil cylinder, it is characterized in that: vibration damper is made of large and small two liquid-springing oil cylinders, and the bottom of big liquid-springing oil cylinder and the piston rod of little liquid-springing oil cylinder link.
The structure of large and small two the liquid-springing oil cylinders described in the technical solution of the present utility model is identical, diameter is identical, the axial length of big liquid-springing oil cylinder is greater than the axial length of little liquid-springing oil cylinder, and the ratio of described large and small liquid-springing oil cylinder axial length is 1: 0.25～0.5.
The utility model adopts large and small two dydraulic shock absorbers to carry out vibration damping, the large and small pressure of liquid that relies between the two gives timely complementation, when running into little vibration in travelling, by the small-sized hydraulic vibration damper work of below, when running into big vibration, upper and lower two hydraulic vibrators are worked simultaneously, and can adjust damping according to designing requirement, characteristic according to vibration damping object (road conditions) is mutually adjusted, and therefore this multistage vibration damper was both separate, coordinates mutually again; The utility model makes vehicle body and wheel can keep upper and lower independent separately vibration damping all the time, has autobalance, automatic conversion rigidity and damping buffering function, and effectiveness in vibration suppression and resistance to capsizing are realized multistage vibration damping, and vehicle riding comfort, Security etc. are got a promotion; The utility model is simple in structure, compact, volume is little, cost is low, can change with road condition change, is applicable to various automobiles, and the vibration damping of other equipment, and its application area is very wide.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is made of two liquid-springing oil cylinders 3,6 of small one and large one upper and lower arrangement, and the bottom of big liquid-springing oil cylinder 3 connects with the piston rod 7 of little liquid-springing oil cylinder 6, can adopt welding to connect; The structure of large and small two liquid-springing oil cylinders 3,6 is identical, the diameter of two cylinder bodies is identical, the volume difference, the axial length of both big liquid-springing oil cylinder 3 is greater than the axial length of little liquid-springing oil cylinder 6, and the axial length ratio of big liquid-springing oil cylinder 3 and little liquid-springing oil cylinder 6 is 1: 0.25～0.5; The length of the piston rod 2 in the big liquid-springing oil cylinder 3 is greater than the length of piston rod 7 in the little liquid-springing oil cylinder 6, the rigidity that is connected in the spring 5 on the piston 4 in the big liquid-springing oil cylinder 3 is greater than the rigidity that is connected in the spring 9 on the piston 8 in the little liquid-springing oil cylinder 6, and both liquid-springing oil cylinder 6 was big liquid-springing oil cylinders 3 of scaled down version; When running into little vibration in the automobile running, little liquid-springing oil cylinder 6 work, when only running into big vibration, large and small liquid-springing oil cylinder 3,6 is just worked simultaneously; Be connected with fixed support cover 1 respectively at the top of big liquid-springing oil cylinder 3 and the bottom of little liquid-springing oil cylinder 6, be with the rubber bushing 10. that can play damping effect on the fixed support cover 1
