Abstract
A height adjusting system for a motorcycle body 1 comprises front and rear telescopic suspensions 2, 6 and 3, 7 respectively connected to the axles of the two wheels 4, 5 and a high pressure air tank 18 connected to the two suspensions and pressurized by an air pump 19 driven by a motor 20 supplied by a battery 23. A movable contact 25 driven by the speedometer of the motorcycle engages a fixed contact 26 when the motorcycle is either stopped or running at a low speed and completes a circuit to leak valves 10 and 11 to exhaust the suspensions 2 and 3. Electro-magnetic valves 16 and 17 also exhaust the tank 18 through check valves 14 and 15. When the motorcycle runs at a higher speed the movable contact 25 engages a second fixed contact 27 to energize the motor 20 to drive the pump 19 to pressurize the tank 18. The leak valves 10 and 11 are closed and the increase of pressure raises the motorcycle body until a predetermined level is reached when pressure responsive change-over switches 12 and 13 are operated to close the valves 16 and 17 and stop the motor 20.
