Systems and methods for controlling wheel motion during a collision are provided. A retaining member may be connectable between a vehicle frame and a wheel assembly to control motion of the wheel assembly during a collision of a vehicle with an object. The retaining member may include one or more of a first attachment point connecting the retaining member to the vehicle frame, a second attachment point connecting the retaining member to the wheel assembly, a retaining member routing, and/or one or more break-away connections attaching the retaining member to the vehicle frame and/or to the wheel assembly. The first and second attachment points, retaining member routing, and/or break-away connections may be selected to control motion of the wheel assembly within a preferred path to control loading between the object and the vehicle.

A suspension assembly for a vehicle axle. The assembly comprises a support structure, a housing element rotatably connected, about a transverse axis, to a support element in which the support structure is configured in a such a manner that it can rotate in relation to the support element about the longitudinal axis of the vehicle and is secured to the main chassis of the vehicle by a pair of hydraulic cylinders. The support structure comprises a pair of main guides, which can be fixed to the main chassis and a rolling element which slides between the pair of main guides and a contact element with a pair of further guides, the contact element operatively associated with the pair of further guides so as to come into contact with one of the further guides following a rotation about the rolling element.

A clutch apparatus for a stabilizer may include: an inner race fixed to a first transmission bar, with a first guide recess part formed in a longitudinal direction in an outer surface of the first transmission bar; a housing fixed to a second transmission bar and installed in a shape enclosing the outer surface of the inner race, with a second guide recess part formed in the housing at a position facing the first guide recess part; a ball disposed between the inner race and the housing and having opposite sides respectively inserted into and retained in the first guide recess part and the second guide recess part; and a driver disposed inside the housing and configured to move the ball along the first guide recess part and the second groove and control power transmission between the inner race and the housing.

A level control system for a vehicle, in particular a rail vehicle, includes at least one level control cylinder and one level control piston, the level control piston being movably guided in the level control cylinder in order to adjust the level of the rail vehicle, the level control piston having an outer piston sleeve and a piston main body at least partially accommodated in the piston sleeve, and the piston main body being slidable relative to the piston sleeve for wear readjustment and being lockable and/or fixable in at least two adjustment positions.

A gearing arrangement for an actuator device for height adjustment of a vehicle body is provided, having a drive wheel and an output wheel, which are rotatably connected to each other by a tooth system formed on each. A blocking element is arranged on the output wheel to block a rotational movement, and a guide track having a blocking stop integrated therein and at least one deflection position; the guide track is connected to a pin section, which is movable to a limited degree and which is provided in order to be guided along the guide track upon rotation of the output wheel and to block a rotational movement of the output wheel upon penetrating into the blocking stop. By using the at least one deflection position, the rotative position of the blocking element can be detected during guiding of the pin section by the at least one deflection position.

The invention relates to an axle suspension on a vehicle frame, comprising: an axle bracket which in its longitudinal direction is arranged transversely to the vehicle frame and at its longitudinal ends each is provided with a wheel carrier, a pendulum support which is connected with the axle bracket via a swivel bearing and is accommodated in a self-aligning bearing attached to the vehicle frame, wherein the swivel bearing has a swivel axis which extends parallel to the longitudinal axis of the vehicle frame.

An actuator for level adjustment of a motor vehicle utilizes a ball screw and a locking unit provided for blocking the ball screw. The actuator has a spindle drive which can be actuated by an electric motor via a gear. The spindle may be fastened to a damper of the chassis of a motor vehicle, to a wheel carrier or to the body or a subframe of a motor vehicle. With the aid of a locking unit of the spindle drive, the rotation of the spindle nut can be optionally blocked or enabled. The locking unit includes a locking element which engages a locking contour attached to the end face of a rotatable element of the gear.

A suspension module includes a spindle pivotably connected to an axle with a pivot element defining a vertical axis. The spindle has an attachment member and an attachment cap, with outer ends are rigidly interconnected by a pair of lift cylinders. The spindle includes a plate extending between the lift cylinders intermediate the attachment member and cap with the pivot element received between the attachment member and plate. Each lift cylinder has a ram movable within a housing of the lift cylinder. A wheelbox mounts to the wheel and couples with the spindle. First and second strut rods connect the wheelbox with the ram of one of the lift cylinders, and third and fourth strut rods connect the wheelbox with the ram of a second lift cylinder. The strut rods allow the spindle to move relative to the wheelbox while also transferring pivot torque between the wheelbox and the spindle.

A motor vehicle wheel suspension, comprising a guide wheel having an outer jacket comprising a wheel attachment for the connection of the guide wheel to a rotation pin of a wheel. The guide wheel extends between opposite axial upper and lower ends in correspondence of which it comprises attachments for its connection to connection elements of an associated frame, wherein said outer jacket internally encloses a damper and a spring. The outer jacket, in correspondence of one of said axial upper and lower ends comprises a slot for realizing a first attachment to connection elements of the frame, said slot housing a pin axially guided by said slot, the slot connecting a cavity inside the outer jacket with said pin. The outer jacket, in correspondence of the other of said axial upper and lower ends comprises a tilting hinge for realizing a second attachment to connection elements of the frame.

The invention proposes a method of supplying with hydraulic fluid a hydraulic motor (2) of a drive wheel supporting a vehicle by means of a cylinder-type suspension system (1). The hydraulic fluid passes through a feed duct (25) extending longitudinally through a cylinder (3) of the cylinder-type suspension system (1). The invention also relates to the use thereof in order to eliminate the need for hoses.
