Abstract

The invention relates to the technical field of vehicle suspension systems, in particular to a vehicle suspension shock absorber which comprises an upper suspension positioning plate, a hydraulic damper, a lower suspension positioning screw sleeve and a regulating nut, wherein the upper suspension positioning plate and the lower suspension positioning screw sleeve are respectively positioned at the upper end and the lower end of the hydraulic damper, the regulating nut is positioned on the middle part of the hydraulic damper, and a rubber air bag is arranged on the hydraulic damper. According to the vehicle suspension shock absorber, because the rubber air bag is used for replacing a steel spring, the vehicle suspension shock absorber not only has a simple structure and can be deflected and subjected to flexure, but also flexible motions of automatic control can be realized so as to improve the shocking proof effect and the comfort of a travel process of a vehicle.

Description

The automobile hanging vibration damper
Technical field
The present invention relates to the automobile suspension system technical field, especially a kind of automobile hanging vibration damper.
Background technique
Easily being hit at the suspension holdfast system Elastic element of automobile produces vibration, in order to improve the smoothness of automobile running, in the suspension holdfast with elastic element on mounting dampers, be its attenuation vibration.Adopt vibration damper to be mostly that hydraulic retarder and steel spring (spring steel material is made) are assembled into vibration damper in the automotive suspension bracket system, its working principle is when vehicle frame or vehicle body and vehicle bridge part are subjected to vibration relative movement to occur, piston in the resistance of shock absorber is mobile simultaneously up and down, and the fluid of resistance of shock absorber inner chamber just flows in another chamber through different holes from a chamber repeatedly.The at this moment interior friction of the friction of hole wall and fluid and fluid molecule forms damping force to vibration, and the Conversion of Energy that makes automobile vibration is fluid heat energy, is absorbed to be dispersed in the atmosphere by vibration damper again and goes.Meanwhile steel spring is just done the damping vibration attenuation motion simultaneously with resistance of shock absorber, improves the smoothness of automobile running.Above-mentioned existing vibration damper is that hydraulic retarder and steel spring are assembled into vibration damper, is mechanical, and during the motion of steel spring, power is rigid of transmission, namely can not realize the compliant motion of automation control, and shock-proof effect is poor, and comfort level is low.
Summary of the invention
Poor in order to overcome existing vibration damper shock-proof effect, the deficiency that comfort level is low the invention provides a kind of automobile hanging vibration damper.
The technical solution adopted for the present invention to solve the technical problems is: a kind of automobile hanging vibration damper, comprise outstanding positioning plate, hydraulic retarder, lower outstanding positioning screw rotation set and adjusting nut, upper outstanding positioning plate and lower outstanding positioning screw rotation set lay respectively at the up and down two ends of hydraulic retarder, adjusting nut is positioned at the middle part of hydraulic retarder, and hydraulic retarder is provided with rubber pneumatic bag.
According to another embodiment of the invention, comprise that further rubber pneumatic bag is enclosed between outstanding positioning plate and the adjusting nut.
According to another embodiment of the invention, the two ends that further comprise rubber pneumatic bag are fixed on the hydraulic retarder by upper outstanding connecting plate and lower outstanding connecting plate.
According to another embodiment of the invention, comprise that further rubber pneumatic bag is provided with the control device of air.
The invention has the beneficial effects as follows, adopt rubber pneumatic bag to replace steel spring, but not only deflection simple in structure, flexible, and can realize the compliant motion that automation is controlled, thus improve shock-proof effect and vehicle traveling process travelling comfort.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
Outstanding positioning plate on 1. among the figure, 2. on outstanding connecting plate, 3. rubber pneumatic bag, 4. hydraulic retarder, 5. time outstanding connecting plate, 6. adjusting nut, 7. time outstanding positioning screw rotation set, 8. control device of air.
Embodiment
Structural representation of the present invention such as Fig. 1, a kind of automobile hanging vibration damper, comprise outstanding positioning plate 1, hydraulic retarder 4, lower outstanding positioning screw rotation set 7 and adjusting nut 6, upper outstanding positioning plate 1 and lower outstanding positioning screw rotation set 7 lay respectively at the up and down two ends of hydraulic retarder 4, adjusting nut 6 is positioned at the middle part of hydraulic retarder 4, and hydraulic retarder 4 is provided with rubber pneumatic bag 3.Rubber pneumatic bag 3 is enclosed between outstanding positioning plate 1 and the adjusting nut 6.The two ends of rubber pneumatic bag 3 are fixed on the hydraulic retarder 4 by upper outstanding connecting plate 2 and lower outstanding connecting plate 5.Rubber pneumatic bag 3 is provided with control device of air 8.
The working principle of this vibration damper is when vehicle frame or vehicle body and vehicle bridge part are subjected to vibration relative movement to occur, piston in the hydraulic retarder 4 is mobile simultaneously up and down, fluid in its inner chamber just flows in another chamber through different holes from a chamber repeatedly, the at this moment interior friction of the friction of hole wall and fluid and fluid molecule forms damping force to vibration, the Conversion of Energy that makes automobile vibration is fluid heat energy, is absorbed to be dispersed in the atmosphere by vibration damper again and goes.In this simultaneously, rubber pneumatic bag 3 is filled with air or the motion that deflates by control device of air 8, thereby changes the elastic performance of rubber pneumatic bag 3, cooperates hydraulic retarder 4 to do simultaneously the damping vibration attenuation motion.Adopt rubber pneumatic bag 3 to replace steel spring and be used on the vehicle shock absorber, can realize the compliant motion of automation control, thereby improve shock-proof effect and vehicle traveling process travelling comfort.
