example 1

[0128] In this embodiment, a so-called dial device is used as the input device 34 . However, the present embodiment is not limited thereto. In the case where the user can select the weight to put on the motorcycle 1, the input device 34 may be a lever-type device where the user moves a knob linearly, a switch-type device where the user presses a button indicating the weight, or a user presses an on-screen A touch-panel-style device for displaying weight input.

example 2

[0130] In the present embodiment, the weight acquisition unit 575 acquires the weight applied on the motorcycle 1 based on the weight input via the input device 34 provided on the motorcycle 1 . However, the present embodiment is not limited thereto.

[0131] For example, a weight sensor may be provided in the seat 19 of the motorcycle 1, and the weight acquisition unit 575 may acquire the weight applied to the motorcycle 1 based on the weight detected by the weight sensor. When the vehicle speed Vc is lower than the ascending vehicle speed Vu before the height of the vehicle starts to increase, the weight acquisition unit 575 can acquire the weight applied to the motorcycle 1 based on the value detected by the weight sensor.

[0132] For example, the weight acquisition unit 575 may acquire the speed of change of the movement amount determined based on the front wheel movement amount Lf and the rear wheel movement amount Lr after a predetermined period of time elapses after th...

example 3

[0134] When electric power is not supplied to the control device 50, for example, when the engine 17 of the motorcycle 1 is stopped, EEPROM or the like can store the weight applied to the motorcycle 1 obtained at startup, and the weight acquisition unit 575 can read it at the next startup. The stored weight.

Abstract

A vehicle height adjusting apparatus including: a spring disposed between a body of a vehicle and a wheel of the vehicle; a rear wheel damper performing expansion and contraction operations to move operating oil to damp the spring The vibration of the support member, which supports one end of the spring, and moves relative to the shock absorber to change the length of the spring; the jack chamber, which causes the support member to move relative to the shock absorber through the expansion and contraction operation of the shock absorber The moving working oil flows into the jack chamber; the rear wheel solenoid valve adjusts the amount of working oil flowing into the jack chamber through the opening degree of the solenoid valve; and the control device based on the The weight on the valve is used to control the opening of the solenoid valve.

Description

technical field [0001] The invention relates to a vehicle height adjustment device for adjusting the vehicle height of a motorcycle. Background technique [0002] In recent years, devices have been proposed that increase the vehicle height of the motorcycle when the motorcycle is running and lower the vehicle height when the motorcycle is stopped so that a rider can get on and off the motorcycle easily. [0003] For example, a vehicle height adjusting device disclosed in JP-B-H08-22680 has the following configuration. That is, the rear arm is pivotally supported by the rear portion of the vehicle frame of the motorcycle, and the rear wheel is supported in the rear end of the rear arm via the vehicle axle. A hydraulic shock absorber is arranged between the rear arm and the vehicle frame via a connection mechanism. The hydraulic buffer device has a hydraulic damper and a buffer spring. The cover fits into the cylinder head opening and also serves as a bracket for the cylind...
