Disclosed is a self-balancing device for self-propelled off-road RV box body. The self-balancing device includes an auxiliary beam body for connecting with a bottom end of the RV box body, a front triangular balance beam body, a rear triangular balance beam body and an axle-holding device for connecting with a RV chassis girder. The front triangular balance beam body and the rear triangular balance beam body are arranged close to both ends of the auxiliary beam body respectively. The axle-holding device is arranged between the front triangular balance beam body and the rear triangular balance beam body. Both the front triangular balance beam body and the rear triangular balance beam body include a hard limit structure for limiting a swing angle of the RV box body. The axle-holding device includes a soft limit structure for horizontally resetting the RV box body.

A torsion bushing includes a body portion defining a torsion rod-receiving bore, one or more helical flexion ribs defining at least a portion of the torsion rod-receiving bore, and a helical lubrication reservoir adjacent to the one or more helical flexion ribs. The torsion bushing may be included in a torsion busing assembly that further includes a bracket. The bracket may have a saddle to receive the torsion bushing, and one or more flanges for coupling the bracket to a frame. The torsion bushing may be included in a torsion rod assembly that further includes the bracket and a torsion rod.

A method of operating an adjustable roll stabilizer (1) of a motor vehicle. The adjustable roll stabilizer (1) has an actuator (2) which can be rotated through a system angle (α) relative to a rotational axis (3) in order to twist two stabilizer sections (6a, 6b), connected thereto, relative to one another. The stabilizer sections (6a, 6b) are each a radial spaced away from the rotational axis (3) and each is coupled to a wheel suspension (7a, 7b, 8a, 8b, 9a, 9b). The method includes controlling the actuator with a field-orientated regulator (20) as a function of input signals which include at least a target motor torque (21), and checking the control of the actuator (2), brought about by the field-orientated regulator (20), for plausibility independently of the field-orientated regulator (20).

A suspension assembly for a vehicle may include a first stabilizer bar operably coupled to a first wheel on a first side of the vehicle, a second stabilizer bar operably coupled to a second wheel on a second side of the vehicle, and an chassis coupler comprising an inverter housing and an actuator assembly. The actuator assembly may be operable to arrange the first stabilizer bar and the second stabilizer bar in a selected one of a connected state, a disconnected state, and an inverted state. The inverter housing may be alternately constrained to one of the first stabilizer bar or the chassis coupler based on a position of the actuator assembly to define each of the connected state, the disconnected state and the inverted state.

A method of operating an adjustable roll stabilizer (1) of a motor vehicle. The adjustable roll stabilizer (1) includes an actuator (2) which can rotate relative to a rotational axis (3) in order to twist two stabilizer sections (6a, 6b) connected thereto relative to one another about the rotational axis (3). The stabilizer sections (6a, 6b) are radially spaced away from the rotational axis (3) and each is coupled to a wheel suspension (7a, 7b, 8a, 8b, 9a, 9b). The actuator (2) is controlled on the basis of a system target torque specified for the vehicle, and the specified system target torque is tested for acceptability in relation to a roll torque distribution (β) that is acceptable for the motor vehicle.

Provided is a vehicular holding device that, in an ON state, holds a vehicle component in a state where displacement of the vehicle component in an axial direction is restrained, and that, in an OFF state, holds the vehicle component in a state where displacement of the vehicle component in the axial direction is possible. The vehicular holding device includes at least one engagement part, a cam mechanism, and an axial direction restraining part. The at least one engagement part is at a position where the engagement part engages with an engaged part in the ON state, and is at a position where the engagement part is separated from the engaged part in the OFF state. The cam mechanism displaces the at least one engagement part from the OFF-state position to the ON-state position. The axial direction restraining part receives axial-direction force acting on the at least one engagement part.
