よってソレノイドパルプ!&14に接続されている。A high vehicle height sensor 20 and a low vehicle height sensor 2σ are installed between the rear intermediate portion of the vehicle body frame 2 and the approximately intermediate portion of the swing arm 7. A cushion unit 1G is provided with a high vehicle height sensor 20 and a low vehicle height sensor 2σ.
Vehicle height sensor 2G that detects the vehicle height (tilted pupil of swing arm 7) that changes due to the operation of
, 20' not only detects the vehicle height, but also compares the detected value with preset height values and generates a signal. And to this both vehicle height sensor 2
σ is connected to the control unit 220 input signal by an electric wire 21. The output side of the control unit 22 is
Therefore, solenoid pulp! &14 is connected.

とKなる。The front wheel 5 has rectangular teeth 25 engraved over the entire W4, and a mourning gear 26 is attached thereto so that the front wheel 5 rotates once integrally with the front wheel 5. A vehicle speed sensor 27 is provided near the outer edge of the vehicle 26. This vehicle speed sensor 27 detects the vehicle speed by counting the teeth 25 (Da) of the rotating gear 26.The output signal thereof is given to the control unit 22 by the electric current 1i28.

地上高とバンク角等を得ることができる。Motorcycles that have failed this vehicle height adjustment device configured in this manner have the high vehicle height sensor 20 set to the high vehicle height limit [
Set K and set the low vehicle height sensor 20' to the lower limit of vehicle height O
Use by setting it to 1. From this K, vehicle speed or set speed 11
(f'i is the speed WE when it is thought to be stopped) When the following conditions are met, K maintains the low vehicle height set by the low vehicle height sensor 20', thereby improving the driver's footing and ensuring that the vehicle speed is higher than the set speed. In this case, a high vehicle height sensor 20 is used to maintain a good vehicle height and obtain minimum ground clearance, bank angle, etc.
作動をWI&明すると、車速か設定速度以下になったと

ッションユニット10とパイプ11.12中の空気を大
気開放口19から大気中に開放し、車高を下げる。The control unit 22tj issues a command to open the renoid valve 14. From this point, the solenoid pulp 14 releases the air in the cushion unit 10 and the pipes 11 and 12 to the atmosphere through the atmosphere opening 19, thereby lowering the vehicle height.

の位置に保持される。Since lowering the vehicle height means that the cushion unit 1G contracts, the high/low vehicle height sensor 2a20 also contracts, and a signal commensurate with the contraction 1iK is given to the control unit 22. When the vehicle height drops to the height set by the vehicle height sensor 20, the solenoid pulp 14 closes in response to a command from the control section 22. From this K, the vehicle height is maintained at that position.

とになる。When the solenoid pulp 13 opens, the compressed air stored in the air tank 17 is released from the pipe 18. It is applied to the cushion unit lO through lλ11, and by extending it, the vehicle height is increased. In this case, high vehicle height sensor 2
When the vehicle rises to the vehicle height set at 0, the solenoid pulp 13 closes, and the higher vehicle height is maintained.

d1低車高センサー20は不要となる。In the embodiment described above, two vehicle height sensors, the high vehicle height sensor 20 and the low vehicle height sensor 20', are used, but it is also possible to use only one vehicle height sensor, that is,
Cushion: Use a cushion with both a coil spring and an air spring as L = 10, and set the lower car and horse position to the cushion (22) 1G, and the air pressure in 1G is atmospheric pressure, and it is supported only by the coil spring. The low vehicle height sensor 20 becomes unnecessary due to the setting deviation d1 in the position.
