Abstract
The utility model relates to shock-damper for motive vehicles. In the utility model, a gas filling cylinder is respectively arranged on steel sheet springs between the left and the right of a vehicle chassis and the left and the right of an axle, and a partition board which divides the gas filling cylinder into an upper chamber and a lower chamber is arranged in the gas filling cylinder. A one-way valve and a gas deflating hole are arranged on the partition board in parallel. The upper chamber is communicated with a gas storage tank, and the upper part of the upper chamber has an upper joint. A spacer pin is arranged on the wall of the lower part of the lower chamber, the lower end is sheathed with a dust-proof cover, and one end of a piston rod in the lower chamber has a lower joint. The circumstance of the piston is sheathed with sealing rings, and the bottom part of the gas storage tank is provided with a gas charging hole and a gas discharging hole, which are communicated with the hole arranged the change-over valve by pipes. The other hole of the change-over valve is communicated with a braking gas source.
Description
The utility model relates to a kind of motor vehicle damper, and the vibration damper of best chassis height especially can be provided to Motor Vehicle according to the different cargos of Motor Vehicle and road surface.
The vibration damper that the current mobility car is used mainly contains board-like vibration damper of spring steel and damped type vibration damper.Because the inherent characteristic of steel plate makes Motor Vehicle produce oscillating type vibrations, particularly Steel Spring Plate vibration damper easily, makes the chassis height of Motor Vehicle, what change with loading, can not bring into play the effect of vibration damper best; And the damped type vibration damper can only be attached on the spring damper, is difficult to the truck conspicuity marking damping, and is same, and the chassis height of Motor Vehicle changes what with loading, can not bring into play best damping effect.
The purpose of this utility model is to provide a kind of vibrations that can not only eliminate Motor Vehicle well for fear of above-mentioned the deficiencies in the prior art part, and a kind of adjustable motor vehicle pneumatic cushion shock absorber of best chassis height is provided can for Motor Vehicle when different cargos and road traveling.
In order to achieve the above object, the utility model is on the left and right and vehicle bridge steel sheet spring between left and right, an inflating cylinder to be installed respectively accordingly at motor-vehicle chassis; In inflating cylinder, be provided with an isolating plate, inflating cylinder is isolated into epicoele and cavity of resorption; On isolating plate, be provided with one-way valve and bleeder port side by side; Epicoele communicates with gas tank by connecting tube, is provided with upper connection on epicoele top, on the wall of cavity of resorption bottom position limit pin is arranged, and is with boot seal in the cavity of resorption underpart; Intrinsic piston rod on the piston in cavity of resorption; The piston rod the other end is provided with lower contact, is with seal ring around the piston, have in the gas tank bottom fill, vent hole, this pore joins by one hole of the changing valve in tracheae and the operator cabin, another hole of changing valve joins with the source of the gas that brakes.
Described inflating cylinder epicoele is a cone barrel type;
Described piston is the back taper bodily form;
The volume of described gas tank is greater than the volume of inflating cylinder;
The volume of accumulation body jar is 1～2 times of inflating cylinder volume.
The utility model beneficial effect compared with prior art:
After the utility model is taked technique scheme, can make Motor Vehicle both reach damping effect, controller motor-car chassis height easily makes Motor Vehicle adapt to different cargos and road surface situation best again.
Accompanying drawing is a front section view of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in drawings, be provided with isolating plate 2, inflating cylinder 1 is isolated into epicoele 1a and cavity of resorption 1b in inflating cylinder 1 inner upper end.On isolating plate 2, be provided with one-way valve 3 and bleeder port 4 side by side.Epicoele 1a joins by tracheae 5 and gas tank 6; Epicoele 1a top is provided with ring-type upper connection 7, and position limit pin 13 is housed on the wall of cavity of resorption 1b bottom, is with stretchability boot seal 8 in outside, cavity of resorption 1b lower end; Intrinsic piston rod 10 on the piston 9 in cavity of resorption 1b, piston rod 10 the other ends are provided with ring-type lower contact 11, around piston 9, be with seal ring 12, be provided with in gas tank 6 bottoms fill, vent hole 14, pore 14 is connected into by breathing pipe on the hole of the changing valve in the operator cabin, and an other hole of changing valve joins by tracheae and brake source of the gas.
Using method and process:
The upper connection 7 of left and right sides cylinder 1 is connected on the motor-vehicle chassis, lower contact 11 is connected on the vehicle bridge of Motor Vehicle, gas tank 6 is fixed on the motor-vehicle chassis, the filling of gas tank 6, vent hole 14 are received on the hole of automobile driving cabin internal conversion valve by tracheae, the source of the gas that will brake is received on another hole of changing valve by connecting tube, inflate to gas tank 6 with brake air by changing valve, and then enter the epicoele 1a of inflating cylinder 1, enter cavity of resorption 1b by bleeder port 4, compressing piston 9 moves down, the chassis is raise, improve the roadblock ability of passing through of Motor Vehicle; Otherwise outwards exit by changing valve, the chassis is descended.When Motor Vehicle when the roadblock, vehicle bridge rises, thereby piston 9 is risen, the air in the compression cavity of resorption 1b, at this moment, cavity of resorption 1b internal air pressure backs down one-way valve 3 greater than the air pressure in epicoele 1a and the gas tank 6, to gas tank 6 venting; When vehicle bridge descends, by lower contact 11 piston 9 is descended, cavity of resorption 1b internal air pressure is reduced, one-way valve 3 is closed, thereby the gas in the gas tank 6 pass through bleeder port 4 slowly to cavity of resorption 1b inflation, thus the cushioning effect of playing.
