Abstract
The utility model relates to a shock absorber for vehicles, which comprises a hydraulic cylinder, a pressure bearing piston and a pressure bearing spring, and is particularly provided with a pressure bearing plate and a pressure transmission piston. The pressure bearing plate is positioned above the hydraulic cylinder. The upper end of the pressure bearing piston is fixed on the pressure bearing plate, and the lower end of the pressure bearing piston is sheathed in a pressure bearing piston sleeve of the hydraulic cylinder. The pressure bearing spring is positioned in the position between the lower surface of the pressure bearing plate and the hydraulic cylinder. The lateral wall of the hydraulic cylinder is transversely provided with a pressure transmission piston cavity which is communicated with an inner cavity of the hydraulic cylinder, and the front end of the pressure transmission piston is sheathed in the pressure transmission piston cavity. The back part of the pressure transmission piston is provided with a pushing spring, and the back end of the pushing spring is fixed on the hydraulic cylinder.
Description
The utility model relates to a kind of vehicle vibration damper.
Existing various motor vehicle damper is more, but structure is all comparatively complicated, and damping effect is also unsatisfactory.China's utility application discloses a kind of stabilizer for motor-vehicle No. 96110166.0, it comprises master hydraulic cylinder and guiding hydraulic cylinder, be fixed with the pressure-bearing plunger bushing on the master hydraulic cylinder wall, pressure-bearing plunger, pressure-bearing spring and regulator bolts are housed in the pressure-bearing plunger bushing, be fixed with atmospheric communicating pipe on the master hydraulic cylinder wall, one end of atmospheric communicating pipe is fixed on the pressure-bearing plunger jacket wall, and by being communicated with connecting tube, an end of pilot spool is sleeved in the guiding hydraulic cylinder between guiding hydraulic cylinder and the master hydraulic cylinder.Master hydraulic cylinder, guiding hydraulic cylinder and connecting tube intracavity space be filled with hydraulic oil.Tool claims this device to eliminate or to reduce Motor Vehicle to shake amplitude, reduces Motor Vehicle because of shaking the damage that causes, the increase ride quality.But the structure of this device is comparatively complicated, thereby also exists defective.
The purpose of this utility model provides that a kind of structure is comparatively simple, damping effect vehicle shock absorber preferably.
Vehicle shock absorber of the present utility model has oil hydraulic cylinder, pressure-bearing piston and pressure-bearing spring, the top of described oil hydraulic cylinder has the pressure-bearing piston cover with the oil hydraulic cylinder intracavity inter-connection, it is characterized in that being provided with bearing plate and pressure transmission piston, described bearing plate is positioned at the top of oil hydraulic cylinder, the upper end of pressure-bearing piston is fixed on the bearing plate, the lower end of pressure-bearing piston is placed in the pressure-bearing piston cover of oil hydraulic cylinder, the pressure-bearing spring is between the lower surface and oil hydraulic cylinder of bearing plate, be horizontally arranged with pressure transmission piston cavity with the oil hydraulic cylinder intracavity inter-connection at the sidewall of oil hydraulic cylinder, the front end sleeve of described pressure transmission piston places in this pressure transmission piston cavity, the rear portion of described pressure transmission piston is provided with the goring push spring that imposes jacking force to the rear portion of pressure transmission piston, and the rear end of this goring push spring is fixed on the oil hydraulic cylinder.In the utility model, above-mentioned pressure-bearing piston can be one or more, and the pressure transmission piston also can be one or more.When a plurality of pressure-bearing piston is set, corresponding with it a plurality of pressure-bearing piston covers should be arranged also on oil hydraulic cylinder.In like manner, when a plurality of pressure transmission piston is set, on the sidewall of oil hydraulic cylinder, also should a plurality of pressure transmission piston cavity be set correspondence.When using damping device of the present utility model, oil hydraulic cylinder can be fixed on the car body, and allow bearing plate partly as the load-bearing of vehicle.When causing vibrations because of the road out-of-flatness, pressure-bearing piston can be in upper and lower motion in the pressure-bearing piston cover, and by the liquid transfer pressure in the oil hydraulic cylinder, allow the effect of being stressed of the pressure transmission piston of cross setting and forward and backward motion in the pressure transmission piston cavity (being positioned at the goring push spring movement therewith at pressure transmission piston rear portion), the corresponding shockproofness of subduing reaches the damping purpose.In the utility model, can in oil hydraulic cylinder, add an amount of air, so that in oil hydraulic cylinder, form cushioning effect, further improve damping effect.In addition, also can set up plastic cap or plastic plug, also can on piston, set up metal or plastic hoop, so that lower wearing for piston and the maintenance of being convenient to piston at the front end of pressure-bearing piston and pressure transmission piston.
Vehicle shock absorber of the present utility model compared with the aforementioned existing similar products, its structure is comparatively simple, damping effect is also better.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Fig. 1 is the structural representation of vehicle shock absorber among the embodiment.
As shown in Figure 1, the vehicle shock absorber in the present embodiment has oil hydraulic cylinder 1, pressure-bearing piston 2 and pressure-bearing spring 3, has the pressure-bearing piston cover 4 with the oil hydraulic cylinder intracavity inter-connection at the top of oil hydraulic cylinder 1.Be provided with bearing plate 5 and pressure transmission piston 6 in the present embodiment especially.Bearing plate 5 is positioned at the top of oil hydraulic cylinder 1.The upper end of pressure-bearing piston 2 is fixed on the bearing plate 5, and the lower end of pressure-bearing piston 2 is placed in the pressure-bearing piston cover 4 of oil hydraulic cylinder.Pressure-bearing spring 3 is between the lower surface and oil hydraulic cylinder 1 of bearing plate 5.Be horizontally arranged with pressure transmission piston cavity 7 with the oil hydraulic cylinder intracavity inter-connection at the sidewall of oil hydraulic cylinder 1, the front end sleeve of pressure transmission piston 6 places in this pressure transmission piston cavity 7.Be provided with goring push spring 8 at the rear portion of pressure transmission piston 6, this goring push spring 8 imposes jacking force to the rear portion of pressure transmission piston 6.The rear end of goring push spring 8 is fixed on the oil hydraulic cylinder 1.In the present embodiment, above-mentioned pressure-bearing piston 2 is a plurality of, and 6 in pressure transmission piston is left and right two.In the vibration damper process of using present embodiment, when vibrations take place in vehicle, the pressure-bearing piston 2 corresponding upper and lower motions in inside at pressure-bearing piston cover 4, liquid in the oil hydraulic cylinder 1 can pass to pressure transmission piston 6 with consequent pressure, allow the effect of also being under pressure of the pressure transmission piston 6 of cross setting and forward and backward motion in the pressure transmission piston cavity simultaneously, is positioned at goring push spring 8 movement therewith at pressure transmission piston 6 rear portions, the shockproofness of vehicle obtains decay, thereby reaches damping effect.
