Problems solved by technology

[0004] The necessary components involved in such a leveling device are therefore relatively expensive and their assembly relatively cumbersome
In addition, there is the problem that since the leveling device is connected to the vehicle frame via thrust bushings and adapter sleeves without sound insulation, this design is disadvantageous, for example, in the event of noise generation

Embodiment Construction

[0028] figure 1 A device 1 for leveling a motor vehicle is shown, comprising a piston-cylinder unit 2 with a cylinder 3 and a piston 4 movable in the cylinder 3, the piston 4 being connected to the chassis via a vibration-damping bearing in a manner not shown in detail , while the cylinder 3 is connected on the wheel carrier side in a manner not shown in detail.

[0029] In addition, a spring 5 is provided which is elastically compressed and springs back in a known manner during operation, wherein this movement is damped by the piston-cylinder unit 2 which acts as a damping device. The bottom position of the spring 5 is supported on a disc element 6 which can be moved axially on its side by means of a ball screw drive, so that the spring bottom position for level adjustment can be raised or lowered. In addition to ball screw drives, different screw drives can also be used.

[0030] The ball screw drive 7 comprises a nut 8 which extends and moves axially on a threaded rod 9 g...

Abstract

The invention discloses a device for leveling a motor vehicle comprising a damping device with a piston-cylinder unit (2) and a threaded drive (7) comprising a screw (9) and passing through rolling elements The nut (8) supported on the screw rod, the disc member (6) supporting the spring (5) of the damping device is connected to the nut, wherein the nut can be moved along the screw rod (9 ) axial movement, wherein the adapter sleeve (12) placed in the screw (9) and axially supporting the screw is provided with a radially inwardly directed flange (13), the adapter sleeve Axially supported on the cylinder (3) of the piston-cylinder unit (2) via the flange (13), wherein the adapter sleeve (12) is mutually connected to the cylinder (3) on the wheel carrier side Torsion resistant, and wherein the adapter sleeve (12) is soundproofed from the cylinder (3) by at least one elastic element (15, 17).

Description

technical field [0001] The invention relates to a device for leveling a motor vehicle, comprising a vibration damping device with a piston-cylinder unit and a threaded drive device, the threaded drive device comprising a screw and a nut supported on the screw by rolling elements, the nut and the support damper The disc part of the spring of the vibration device is connected, wherein the nut can move along the screw rod. Background technique [0002] In today's motor vehicles, there is an increasing number of motor vehicles employing leveling devices that enable the chassis to be raised or lowered relative to the vehicle frame. Such a leveling device comprises a damping device with a piston-cylinder unit which is arranged between the wheel carrier and the chassis and is separated there by means of a damping bearing. The piston-cylinder unit includes a spring, the bottom position of which can be adjusted, for example by means of a ball screw drive, for leveling the motor vehi...
