Problems solved by technology

Currently commercially available level control systems for vehicles are relatively expensive and heavy
Furthermore, they require a large amount of installation space and, during operation, require a relatively large amount of energy to perform the height adjustment and maintain the set level

Embodiment Construction

[0092] figure 1 A schematic diagram showing a first exemplary embodiment of a device 1 according to the invention for adjusting the height of a vehicle body in a lower position (shown on the left in the figure) or a higher position (shown on the right in the figure). Device 1 includes a wheel suspension part ( figure 1 not shown in further detail) on the spring damping system supported on the vehicle body 2 . The spring damping system comprises a body spring 5, such as a coil spring or a helical spring, fixed between a first spring plate 3 and a second spring plate 4, and a parallel shock absorber 6 with a piston rod 7 and a damping tube 8, in particular It is a single-tube or double-tube gas pressure shock absorber. The piston rod 7 is connected to the first spring plate 3 and the damper tube 8 is connected to the second spring plate 4 . Furthermore, at least one actuating cylinder 9 is mounted between the first spring plate 3 and the vehicle body 2 in a manner that suppor...

Abstract

The present invention relates to a device used for adjusting the height of a vehicle body (2) relative to vehicle wheels, spring damping system on the part of the support to the bodywork of the vehicle wheel suspension with respect to the wheels for the suspension means adjusting the height of the vehicle body (2), comprising for said spring damping system includesBody and fixed to the first and second spring plate (3,4) between the spring (5), and are connected in parallel and includes a piston rod (7) and the damper tube (8), shock absorber (6), the piston rod (7) is connected to the first spring plate (3), the damper tube (8) connected to the second spring plate (4). At least one adjusting cylinder (9) to support the vehicle body (2) are respectively mounted in the first spring plate (3) with the vehicle body (2) or the wheel suspension section.

Description

technical field [0001] The invention relates to a device for adjusting the height of a vehicle body. Background technique [0002] Road vehicles with wheel suspensions that include active or semi-active systems for controlling the level or height of the vehicle body offer different advantages than vehicles with passive wheel suspensions. A constant ground clearance improves driving behaviour, as the wheel compresses and extends independently of the vehicle's load. For example, when driving in a city, i.e. at low driving speeds, it is also possible to raise the height of the vehicle body relative to the ground and thereby increase the ground clearance in order to be able to drive over irregular road surfaces and stones on the side of the road with ease, for example edge, or across a slope whose slope has a steep angle into the underground garage. When traveling at higher driving speeds, the vehicle body can be lowered by means of the level control system, thereby reducing, ...
