- This device comprises a movement thread whose threaded parts can be bridged by a switchable locking device in order to protect the operative engagement between the threaded parts of the movement thread from high mechanical loads.
- An active suspension element which is known from DE 10 2013 222 648 A1 and which works with a ball screw and which serves to adjust a spring receptacle supporting a suspension spring has an additional compensating spring, which is likewise supported on the spring receptacle.
- a device known from DE 10 2009 058 026 A1 for adjusting the height of a vehicle body operates with an actuating means which comprises at least three linear guides arranged so as to be distributed uniformly about a spring longitudinal axis and coupled in a motion-coupled manner via a force transmission element.
- the linear guides are in this case designed to guide a support plate or spring plate.
- a known from DE 10 2008 021 861 A1 Fahrtechniksaktuator comprises in addition to a ball screw a braking device which builds up a mother's rotation or spindle rotation counteracting friction torque.
- the invention has for its object to provide a comparison with the cited prior art further developed connectivity means for a motor vehicle, which is characterized by a particularly robust, stress-resistant structure.
- This object is achieved by a device for level adjustment for a motor vehicle according to claim 1.
- This device that is, level adjustment, comprises a ball screw, which has a threaded spindle, a spindle nut, as well as between the threaded spindle and the spindle nut rolling rolling elements in principle known basic structure.
- an electric motor is provided which directly or indirectly, that is, either in the sense of an electric direct drive or via a transmission, the spindle nut in rotation. Due to the rotation of the spindle nut, a housing of the level adjustment device is displaced linearly relative to the threaded spindle. For storage of the spindle nut in the housing two axial pendulum bearings are provided.
- At least one of these Axialpendellager is arranged in the power flow between the threaded spindle and the housing.
- the threaded spindle is axially fixed in a preferred installation situation via an inner adapter sleeve with a damper or a vehicle body, that is a body and / or a frame, a motor vehicle connected.
- the height adjustment can be realized by the spindle nut with bearing, that is, arrangement of two Axialpendellagern, and housing including a spring plate is moved axially.
- the assembly comprising the threaded spindle and the spindle nut, as a whole in relation to the housing is pivotable.
- a complete assembly which in addition to the housing and the spring plate and a motor, in particular electric motor, and a transmission comprises, as a whole relative to the spindle nut to be pivotable.
- a geometric pivot axis which is not given by the central axis of a shaft or other machine element, may be oriented orthogonal to the central axis of the ball screw. Thanks to this pivotability, tension within the level adjustment device during operation of the motor vehicle under any operating conditions is avoided.
- a tension-free pivotability can be achieved by the two Axialpendellager have a common pivot about which the spindle nut and with this also the threaded spindle is pivotable relative to the housing.
- the avoidance of tension between the threaded spindle and the spindle nut has a positive effect on the efficiency of the ball screw and the entire constitutionalverstellvorraum.
- Of particular importance is achieved with the help of Axialpendellager avoided avoidance of acting on the spindle nut tilting moments, which could affect the life of the level adjustment.
- the coincidence of the centers of the two described by the pivoting movements of the Axialpendellager circles implies that the radii of these circles are not identical, that is, the two Axialpendellager differ from each other at least in terms of the geometry of their bearing discs.
- the geometry of the rolling elements of both axial pendulum bearings can be uniform.
- the pivotability of the spindle nut together with the threaded spindle relative to the housing is limited in a preferred embodiment by an effective between the threaded spindle and the housing slide bearing element.
- the released pivoting angle between the threaded spindle and the housing is preferably at least 1.2 degrees. During operation of the ball screw typically no pivotal movement occurs.
- the Axialpendellager usually remains in a once occupied, tension-free setting.
- said pivoting angle is preferably limited to a maximum of 5 degrees. It is advantageous to keep the pivot angle as small as possible, as long as no tilting moments are introduced into the ball screw.
- one of the two axial pendulum bearings is mainly loaded by axial forces. If, by contrast, the force flow otherwise passing through the ball screw is bypassed by means of a blocking device, as known in principle, for example, from DE 10 2014 206 142 A1, then the spindle nut is in an at least approximately load-free state. In order to guide both Axialpendellager defined in this state, one of the Axialpendellager is preferably acted upon by a biasing member with a force in the axial direction. Instead of a biasing element and a non-resilient shim could be used.
- the axial displacement bearings of the level adjustment device are preferably axial ball bearings.
- axial spherical roller bearings are usable in the level adjusting device.
- the Axialpendellager can be configured either as a single row or as a multi-row pendulum bearing.
- the device for level adjustment can also include the function of a level control in addition to the pure adjustment function.
