The IK is supplied to raise the vehicle height, and when the vehicle height reaches the lower region, the compressed air from the air springs 1 and 10 is discharged to the outside through the exhaust valve 6 to lower the vehicle height. This is a pressure switch provided in the air tank 8, and when the pressure in the air tank 3 is below a predetermined value, the pressure switch 6 drives the motor M of the air compressor 2 to supply compressed air to the air tank 3. However, when the pressure inside the limb air tank 3 reaches a predetermined value, the drive of the motor M is stopped to keep the pressure inside the limb air tank 3 constant. This is a dryer for removing water contained in the compressed air supplied from the Air Compressor 2 to the Air Tank 3 by 8.9.10 Fi Check Pulp. t11 is a vehicle height detection sensor, and ■ is a controller. The vehicle height detection sensor 11 detects the vehicle height, and in the vehicle height up region, the controller n opens the air intake valve 4, and the air springs 1, 1 Supply compressed air to raise the vehicle height, and conversely, when the vehicle height is in the down range, open the exhaust valve 5 with the controller U, exhaust compressed air from the air springs 1, 1, and lower the vehicle height. It looks like this.

あった。By the way, in the conventional vehicle height adjustment device of this type, as shown in FIG. Rubber receiver 1
Due to the presence of 4, the vehicle height reduction amount 1 relative to the standard attitude is calculated by adding the deflection amount δ3 of the bumper rubber due to the sprung mass to the buffer clearance δ (t' - Jt + JIm)
Since the vehicle height cannot be expected to be low, and therefore the ease of loading and unloading cargo during boarding and disembarkation is affected, there is a drawback that even if it is desired to lower the vehicle height as much as possible when the vehicle is stopped, the vehicle height cannot be lowered sufficiently.

従ってバンパーラバー13は、その機能を有効に果す。FIG. 3 shows an embodiment in which a bumper rubber is attached to a piston. In the figure, reference numeral 15 denotes a hydraulic system, and the hydraulic system 15 includes a piston 16 and a cylinder 17 (the cylinder 1
It is attached to the 7a car body. ), oil pump ratio, oil tank 19, check pulp added, relief pulp 2
1. It is equipped with a discharge pulp 4, which drives the motor M of the oil pump 18 during general driving to drain the oil tank 1.
The operating oil of No. 9 is applied to the cylinder No. 1 through the check valve.
7, the pressure inside the cylinder 17 is increased to the set pressure of the relief pulp 21, the piston 16 is pushed down below the cylinder 17, and the desired amount is placed between the bumper rubber 13 and the rubber receiver 14 fixed under the spring. In addition to providing a buffer clearance of 1, it is designed to provide a piston reaction force F=a (effective cross-sectional area of the piston)×P (internal cylinder pressure) that is greater than the input to the piston 16 nibber rubber barro. Preferably, the stop motor is configured to automatically stop when the piston 16 is lowered to a predetermined position. 〈When traveling is stopped (oil pump 18
When the drive of the cylinder 17 is stopped, the discharge pulp n is simultaneously opened to release the pressure inside the cylinder 17. ! 23 indicates a fixing member under the spring.The vehicle height adjustment device of the first embodiment has the above-mentioned configuration, and during normal driving, the piston 16 receives a reaction force F that is greater than the input to the bumper 2 bar 13. As a result, even if the bumper rubber 13 exceeds the desired buffer clearance and collides with the two-part receiver 14, the piston 16 will not be pushed up against the reaction force F.
Therefore, the bumper rubber 13 effectively fulfills its function.

るのである。Next, when one run is stopped (as soon as the oil pump 18 is stopped), the discharge pulp n is opened to release the pressure inside the cylinder 17, so the compressed air is discharged from the air springs 1, 1 and the vehicle height is increased. When lowered, the bumper rubber 13 comes into contact with the rubber receiver 14, but the bumper 2 part 13 to the piston 16 are pushed by the rubber receiver 14 and the ttK cylinder 17
is pushed upwards. Therefore, it becomes possible to increase the amount of vehicle height reduction by the amount of the ticket that is pushed up.

るのである。As explained above, the present invention includes an air spring and an air compressor that supplies compressed air to the air spring, and when the vehicle height increases, compressed air is supplied to the air spring to raise the vehicle height. In a vehicle height adjustment device that lowers the vehicle height by discharging compressed air from an air spring when the vehicle reaches a high down range, the device includes a piston, a cylinder to which the piston is slidably attached, and a hydraulic oil supplied to the cylinder. It is equipped with a hydraulic system equipped with an oil pump for injecting oil, and either a bumper rubber or a rubber receiver is attached to the piston of the hydraulic system so that it can move relative to the other. If you stop driving the oil pump and allow the working oil in the cylinder to drain into the oil tank, etc., when the bumper rubber comes into contact with the rubber receiver and the piston is pushed when the vehicle height is lowered, this will prevent the car from collapsing. Since the piston moves by the time it is pushed, the amount of vehicle height reduction increases by the amount of movement, and it is possible to advantageously improve the ease of getting on and off the vehicle and the ease of loading and unloading cargo.
