A hydraulic height adjustment device of a motor vehicle includes at least one hydraulic pump arrangement connected via feed branch to at least two actuators for adjusting a vehicle level. A hydraulic fluid may be pumped from a tank arrangement into at least one of the at least two actuators. A switching valve may be connected upstream of the actuators to permit or prevent an inflow or outflow of hydraulic fluid. The at least two actuators may be connected via a return branch to the at least one tank arrangement. A pilot pressure-controlled return valve may be configured to hold the return branch open below a defined switching pilot pressure, and the return valve may hold the return branch closed at or above the switching pilot pressure. A pilot pressure line, via which a pilot pressure can be supplied, may be provided between the pump arrangement and the return valve.

A decoupling ring suitable for a planetary gear is disclosed. A decoupling ring includes an annular elastomeric base body and elastomeric formations. In embodiments, the elastomeric formations are uniformly spaced apart from one another, project in the radial direction from the base body, and run parallel to a central longitudinal axis passing centrally through the decoupling ring. With embodiments of the decoupling ring it is possible for the decoupling ring to be arranged on the circumferential side of a ring gear of a planetary gear.

A valve for an air spring includes a housing member having a center axis and channel. The housing member includes first and second elements connected by a materially engaging connection in a first region and in abutment with or directly beside each other in a second region. A sealing member may be disposed in the channel and can close the channel or reduce an effective opening cross section. The valve may comprise a channel element that at least partially guides or forms the channel. The channel element may be fixed in the housing member in a form-fit and/or force-fit manner, and the channel element may retain the sealing member in a third region or the channel element may be fixed in/on the first element in a form-fit and/or force-fit manner, and the channel element may retain the sealing member in a third region.

An electric motor rotor assembly has a central longitudinal axis that runs through the electric motor rotor assembly, at least two structural elements that are arranged coaxially with respect to the central longitudinal axis, and at least one spring element that is arranged between the at least two structural elements in a radial direction and connects the corresponding structural elements such that they are movable relative to each other.

A vibration damper for damping vibrations of a motor vehicle component is disclosed. The vibration damper is passed through by a transverse center plane, and the vibration damper includes a retention apparatus that can be fixed to a motor vehicle component. In embodiments, the vibration damper has at least two receptors that each have an inner side facing the transverse center plane and an outer side facing away from the transverse center plane, has a damper mass with a central longitudinal axis, and has at least two elastomer springs. In embodiments, the elastomer springs couple the damper mass to the receptors with an ability to vibrate, and at least one of the elastomer springs has a connection portion, between the damper mass and respective receptor, that extends at least mainly externally with respect to the respective receptor.

A vibration damper unit having a longitudinal axis includes a damper, a counter bearing that forms a first spring bearing face, a spring that bears against the first spring bearing face, and a base-adjusting device. The base-adjusting device may be offset from the counter bearing along the longitudinal axis and may have a first adjusting partner and a second adjusting partner that is arranged along the longitudinal axis at least partially between the first adjusting partner and the spring and is mounted movably relative to the first adjusting partner in an adjustment direction parallel to the longitudinal axis, has a force-absorbing element for absorbing an adjustment force and forms a second spring bearing face against which the spring bears. In embodiments, the second adjusting partner may comprise a bridging element between the second spring bearing face and the force-absorbing element.

The invention relates to a retaining ring for securing a component. The retaining ring includes a ring segment having an outer circumference for fixing the retaining ring in the axial direction, a recess extending along a circumferential direction of the ring segment, and a closure element for closing off the recess. In embodiments, the ring segment forms a contact surface to fix the component in the axial direction, and the retaining ring has a locking device for locking the closure element in the recess. In embodiments, the locking device is concealed at least on one side of the retaining ring facing away from the contact surface.

An embodiment of a holding structure includes at least one receiving eye with a central receiving axis; at least two fixing points, with each fixing point having a fixing axis that runs parallel to the at least one receiving axis; a first wall and a second wall provided on opposite sides of the holding structure. In embodiments the first wall and the second wall are spaced apart in the direction of the at least one receiving axis; the at least one receiving eye extends from one of the two walls to the other wall; and the holding structure has at least one cavity that is provided between the first wall and the second wall.

The elastic mount element 1 according to the invention for supporting loads in a vehicle, having a longitudinal axis X and a spring element 40, wherein the spring element 40 comprises a mount core 41 and an elastomer 42 vulcanized onto the mount core 41, wherein the elastomer 42 forms at least one lug 43, which projects from the mount core 41, a cartridge 20, which has an undersize relative to the spring element 40 and radially prestresses the spring element 40, wherein the cartridge 20 has a side 21 facing the spring element and a side 22 facing away from the spring element, and a receptacle 10 having an insertion opening for inserting the cartridge 20, wherein the receptacle 10 has a first axial spring travel limiter 11 toward a first end face and a second axial spring travel limiter 12 toward a second end face, and the cartridge 20 is received into the receptacle 10.

A vibration damper unit, through which a longitudinal axis projects, includes a damper with a stop cover element arranged on the end; a foot point adjusting device; a counterbearing, which is situated opposite the foot point adjusting device along the longitudinal axis; a spring, which is supported at one end on the foot point adjusting device; and at the other end on the counterbearing, an auxiliary spring, which is arranged between the foot point adjusting device and the counterbearing and is situated opposite the stop cover element along the longitudinal axis.
