Abstract

The utility model relates to a shock absorber, in particular to a self-balancing shock absorber for a vehicle, which is mounted on a motor vehicle to lower the bumpiness degree of the vehicle. The shock absorber comprises a cylinder body, a piston and a piston rod; wherein, the interior of the cylinder body is divided into an upper cavity and a lower cavity by a baffle plate; the piston comprises an upper piston and a lower piston; the piston rod comprises an upper piston rod and a lower piston rod; the upper piston is positioned in the upper cavity and divides the upper cavity into a first cavity and a second cavity; the lower piston is positioned in the lower cavity and divides the lower cavity into a third cavity and a fourth cavity; an upper oil channel and a lower oil channel are arranged in the wall of the cylinder body; the first cavity and the third cavity are communicated by the upper oil channel; and the second cavity and the fourth cavity are communicated by the lower coil channel. The shock absorber is mounted in the vehicle, and when the vehicle runs on a bumpy road, the shock degree of the vehicle body is automatically reduced, the vehicle can be guaranteed to lie in a balance state when driven on any road, so the shock degree of the vehicle is reduced and the riding comfort of the vehicle is improved.

Description

The automatic balance type vehicular shock absorber

Technical field

The utility model relates to a kind of vibration damper, particularly is installed on the motor vehicle, can reduce the jolt automatic balance type vehicular shock absorber of degree of vehicle.

Background technique

Vibration damper is mainly by cylinder body and the piston that is slidingly matched with it, and the piston rod that connects with piston forms, and piston is positioned at cylinder body cylinder body is separated into two chambeies, fills with hydraulic oil in the chamber.Vibration damper is installed on the vehicle can plays damping effect, can alleviate vehicle jolting in the process of moving to a certain extent.But abominable when vehicle in pavement behavior, have when travelling on the road surface of more pit and convex closure, existing vibration damper just can not play preferably and alleviate the effect that vehicle jolts.

The model utility content

The purpose of this utility model provides a kind of automatic balance type vehicular shock absorber, and it is installed on the vehicle, when travelling on vehicle has the abominable road surface of more pit and convex closure, can alleviate the degree of jolting of vehicle preferably.

Automatic balance type vehicular shock absorber described in the utility model, comprise cylinder body and the piston that is slidingly matched with it, and the piston rod that connects with piston, described cylinder interior is separated into by dividing plate, following two chambeies, described piston comprises upper piston and lower piston, described piston rod comprises upper piston rod that connects with upper piston and the lower piston rod that connects with lower piston, upper piston is positioned at epicoele epicoele is divided into first chamber and second chamber, lower piston is positioned at cavity of resorption cavity of resorption is divided into the 3rd chamber and the 4th chamber, oil duct and following oil duct in cylinder wall, offering, last oil duct is communicated with first chamber with the 3rd chamber, following oil duct is communicated with second chamber with the 4th chamber.

This vibration damper is installed on the motor vehicle, and wherein, upper piston rod is connected with car body, and lower piston rod is connected with wheel by support unit.

When vehicle during in travels down, when if wheel runs into the convex closure on outstanding ground, wheel rises, lower piston rod promotes lower piston and rises, the 3rd cavity volume of cylinder body reduces oil pressure to be increased, hydraulic oil in the 3rd chamber will enter first chamber by last oil duct, thereby the first chamber oil pressure is increased and promote upper piston and move down, and second cavity volume is reduced and the oil pressure increase, hydraulic oil in second chamber will enter the 4th chamber by following oil duct, thereby car body is descended, to a certain degree offset the car body ascensional range that rises and cause because of wheel.

It is same when vehicle drives into pothole, wheel descends, lower piston rod drives lower piston and moves down, the 4th cavity volume of cylinder body reduces oil pressure to be increased, and the hydraulic oil in the 4th chamber enters second chamber by following oil duct, moves on the upper piston thereby make the second chamber oil pressure increase and promote, and first cavity volume is reduced and the oil pressure increase, hydraulic oil in first chamber will enter the 3rd chamber by last oil duct, thereby car body is risen, and to a certain degree offset the car body fall that descends and cause because of wheel.

Vibration damper described in the utility model is owing to have this kind structure, it is installed on the vehicle, when vehicle travels on rough road surface, can be to a certain extent automatically offset wheel run into convex closure and the car body ascensional range that causes, and wheel runs into pit and the car body fall that causes, thereby make vehicle can reduce the Oscillation Amplitude of car body automatically, vehicle body all was in state of equilibrium when the assurance vehicle travelled on any road surface, thereby alleviated the degree of jolting of vehicle preferably, improved the travelling comfort of vehicle ride.

Description of drawings

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1 is the structural representation sketch of automatic balance type vehicular shock absorber described in the utility model.

Embodiment

As shown in Figure 1, this automatic balance type vehicular shock absorber comprises cylinder body 3 and the piston that is slidingly matched with it, and the piston rod that connects with piston, described cylinder body 3 inside are separated into by dividing plate 11, following two chambeies, described piston comprises upper piston 12 and lower piston 6, described piston rod comprises upper piston rod 1 that connects with upper piston 12 and the lower piston rod 7 that connects with lower piston 6, upper piston 12 is positioned at epicoele epicoele is divided into first chamber 2 and second chamber 4, lower piston 6 is positioned at cavity of resorption cavity of resorption is divided into the 3rd chamber 10 and the 4th chamber 9, in cylinder body 3 walls, offer oil duct 13 and following oil duct 5, the opening of last oil duct 13 lays respectively at the casing wall top in first chamber 2 and the 3rd chamber 10, the opening of following oil duct 5 lays respectively at the casing wall bottom in second chamber 4 and the 4th chamber 9, last oil duct 13 is communicated with first chamber 2 with the 3rd chamber 10, following oil duct 5 is communicated with second chamber 4 with the 4th chamber 9.

Upper piston rod 1 is connected with car body 14, and lower piston rod 7 is connected with wheel by support unit 8, when travelling on vehicle has the abominable road surface of more pit and convex closure, can alleviate the degree of jolting of vehicle preferably.
