Embodiment Construction

[0032] The same parts are always assigned the same reference numerals in the different figures, so that they are generally only described once.

[0033] 1A and 1B are schematic side views of a device for adjusting the height of a motor vehicle according to the background art in a first low ( FIG. 1A ) operating state or a second high ( FIG. 1B ) operating state. For the body of a vehicle, in particular a motor vehicle, the device 1 has a helical spring 2 for supporting suspension parts that are movable relative to the motor vehicle body, such as wheel carriers, wheel control arms and the like. The vehicle body and suspension or suspension parts are not shown in FIGS. 1A and 1B .

[0034] As shown in FIGS. 1A and 1B , an air-tight, air-filled air hose 3 made of an extensible material is installed inside the coil spring 2 .

[0035] Furthermore, the device 1 comprises a buffer 4, for example a single-tube buffer or a double-tube buffer. The buffer 4 is connected parallel to th...

Abstract

The present invention relates to a device which is used for adjusting height of an automobile body relative to suspension. The device is provided with at least one spiral spring (2) which is used on the automobile body and supports a suspending part that is movable relative to the automobile body. Furthermore the device is provided with an airtight air hose (3) which is arranged in the spiral spring (2) and can be filled by air and is made of expandable material. The height adjusting device is characterized in that the air pressure in the air hose (3) can be changed by means of penumatic mechanisms (11,12,13) which utilize vibration energy of suspension. The air pressure in the air hose (3) can be changed by means of the pneumatic mechanisms (11,12,13) which utilize the vibration energy of the suspension.

Description

technical field [0001] The invention relates to a device for height adjustment of a motor vehicle body according to the preamble of claim 1 . Background technique [0002] Road vehicles with suspension that incorporate automatic or semi-automatic leveling or height adjustment of the vehicle body offer different advantages compared to vehicles with passive suspension. Since the pitching and bouncing movements of the wheels are largely independent of the load on the vehicle, the technical performance of the motor vehicle can be increased by a fixed ground clearance. It is also possible, for example, to raise the vehicle body relative to the ground at low driving speeds and thereby increase the ground clearance, for example, in order to be able to operate without problems in the event of brake expansion, street corners, etc. The driving or can drive into the underground garage with a larger slope angle. At higher driving speeds, for example to reduce the air resistance of the...
