A floating bearing for a steering gear of a motor vehicle includes a rotary bearing having an inner bearing ring for receiving a screw pinion shaft of the steering gear, and an outer bearing ring built into a bearing sleeve. The bearing sleeve interacts with a guiding element, which interacts with a holding element, such that the bearing sleeve moves relative to the holding element in a first direction oriented radially to the longitudinal axis of the bearing sleeve when the screw pinion shaft is not loaded with torque, and relative movement is prevented when the screw pinion shaft is loaded with torque by moving the bearing sleeve in relation to the holding element in a second direction that is oriented radially to the longitudinal axis and perpendicularly to the first direction, whereby the guiding element is tilted in a guiding opening of the holding element or the bearing sleeve.

A steering column that is adjustable by a motor may include a supporting unit that is attachable to a vehicle body, an actuating unit held by the supporting unit, a steering spindle mounted in the actuating unit rotatably about a longitudinal axis, an adjusting drive for adjusting the actuating unit relative to the supporting unit via a threaded spindle and spindle nut, and a drive unit by which the threaded spindle can be driven rotationally relative to the spindle nut. To improve compactness and greater structural freedom, the drive unit may be connected via a flexible drive connection to a gear unit that can be moved spatially relative to the drive unit.

A steering axle for steering the wheels on the axle of a four-wheel forklift truck by a hydraulic or electric steering device. The steering axle has an axle beam with first and second wheel carriers. The wheel carriers are arranged pivotably on the axle beam. A steering rod is connected, in articulated fashion, to the two wheel carriers in order to transmit steering movements. A steering actuator produces the steering movement and has an actuator housing. The actuator housing has at least one guide section for the passage of the steering rod through the actuator housing. The steering actuator has at least one sliding bearing device for the radial support of the steering rod on the at least one guide section.

A bearing arrangement may be used to mount a worm shaft meshing with a worm wheel in a housing of an electromechanical power steering system. The bearing arrangement comprises a first rotary bearing, a second rotary bearing, and a pivoting ring. The first rotary bearing is configured to permit a pivoting movement of the worm shaft. The pivoting ring comprises a first pivoting ring component and a second pivoting ring component and is configured to act resiliently between the second rotary bearing and the housing. The second rotary bearing is at least partially arranged between the first pivoting ring component and the second pivoting ring component. The first pivoting ring component has two first points, with respect to which the first pivoting ring component is configured resiliently. The second pivoting ring component has two second points, with respect to which the second pivoting ring component is configured resiliently.

A power transmission device including a housing and a ball screw device including a nut, a screw shaft, and a plurality of balls. The device includes a pulley device including a driving pulley configured to be driven by receiving power transmitted from a power source, a driven pulley fixed to the nut, and a belt wound around outer peripheral surfaces of the driving pulley and the driven pulley. The device also includes a first bearing and a second bearing disposed between the housing and the nut in a center axis direction parallel with a center axis of the nut; and a preload applying member configured to apply preloads to the first bearing and the second bearing. The first bearing and the second bearing are respectively disposed on both sides of the driven pulley to be a face-to-face combination, and each of the first bearing and the second bearing includes an outer ring engaged with the housing.

An electromechanical power steering unit for a motor vehicle includes an integral component having a torque sensor unit, which detects the rotation of the upper steering shaft relative to the lower steering shaft. The torque sensor unit includes a ring magnet rotationally fixed to the upper steering shaft and a magnetic flux guide connected to the lower steering shaft. A magnet sensor detects the rotation of the shaft connected to the ring magnet with respect to the lower shaft connected to the magnetic flux guide and the ring magnet is carried by a ring magnet sleeve, which sits on the upper steering shaft and is made from a thermoplastic material and is molded by way of ultrasound forming in the upper steering shaft in one region for mounting on the upper steering shaft.

A steering shaft assembly (10) for a motor vehicle is described, comprising a first shaft (20) and a second shaft (22), both of which are rotatable about a central axis (24). The second shaft (22) is a hollow shaft and a portion of the first shaft (20) is received so as to be axially displaceable inside the second shaft (22). The first shaft (20) and the second shaft (22) are also coupled in a torque-transmitting manner via two rotary coupling mechanisms (26, 28) separate from each other.
