Embodiment Construction

[0013] Referring now to Figures 1-3, a vehicle height adjusting device according to a first embodiment of the present invention that can be used in a vehicle suspension will now be explained. In this embodiment, the vehicle height adjustment device is applied to a suspension in the form of a torque beam comprising a torque beam and a so-called strut, for example a shock absorber arranged separately from the vehicle height adjustment device. In FIG. 1, reference numeral 3 denotes a trailing arm as one side member of the wheel assembly, which is connected to a torque beam. In this embodiment, the vehicle height adjustment device is arranged on the trailing arm 3 . This vehicle height adjusting device includes: an upper suspension coil spring 1U; a lower suspension coil spring 1L; Move the upper suspension coil spring 1U. The upper suspension coil spring 1U is connected to the vehicle body through the upper support member 22 , and the lower suspension coil spring 1L is connecte...

Abstract

The apparatus includes a first suspension coil spring adapted to be connected to a vehicle body, a second suspension coil spring adapted to be connected to a wheel assembly, the second suspension coil spring being different in diameter from the first suspension coil spring and arranged in serial relation to the first suspension coil spring in an axial direction thereof, and an actuator substantially disposed within an inside space defined by the first and second suspension coil springs. The actuator is operative to axially move one of the first and second suspension coil springs relative to the other thereof.

Description

technical field [0001] The present invention relates to a device for adjusting the height of a vehicle body which can be used in a vehicle suspension. Background technique [0002] The document of Japanese Patent Application First Publication No. 7-253135 shows a hydropneumatic cylinder used as a shock absorber in a vehicle suspension. The hydropneumatic cylinder includes a sleeve and a stepper motor that axially drives the sleeve. The stepper motor is arranged upwards above the suspension device. [0003] Such hydropneumatic cylinders in the related art are disadvantageous from the viewpoint of saving space since the stepping motor is arranged above the suspension device. In addition, the hydropneumatic cylinder generates high pressure inside the shock absorber, increasing the friction generated during the impact of the sleeve. This can compromise the comfort of the vehicle occupants. Contents of the invention [0004] An object of the present invention is to provide ...
