The vehicle suspension component includes first and second trailing arms that are spaced from one another for attachment with vehicle wheels. The suspension component also includes at least one cross-member that is rigidly connected with the first trailing arm and is operably connected with the second trailing arm in a non-rigid manner. A rotation inhibitor operably connects the at least one cross-member with the second trailing arm and resiliently resists rotation of the at least one cross-member relative to the second trailing arm.

An axle for a vehicle, wherein the axle includes a transverse axle portion having a longitudinal end. The axle including a first axle portion connecting the transverse portion to a chassis of the vehicle and a second axle portion connecting the transverse portion to a wheel carrier for supporting a vehicle wheel. A vibration damper is arranged in a receiver in one of the axle portions.

A system for opening and closing a closure of a vehicle, such as a door or a tailgate, is provided. The system includes a motor such as an electric motor which may be coupled to the closure via an output linkage, with the output linkage mechanically coupled to the closure and operable to move the closure between a closed position and an open position. The output linkage may include a driven pulley which may be coupled to the motor. The output linkage may include a driven pulley and a cable. The output linkage may include a leadscrew threadedly engaging a nut. A high-bandwidth MR clutch having a high dynamic response may selectively couple the motor with the closure to provide a haptic or tactile feedback to a user interacting with the closure as it is opened or closed.

The twist axle assembly includes a pair of trailing arms that are spaced apart from one another in a first direction. The twist axle assembly also includes a twist beam, which has an open shaped cross-sectional shape, that extends in the first direction between a pair of opposing end portions. The open cross-sectional shape of the twist beam includes a base and a pair of side walls. The end portions of the twist beam are fixedly attached with the trailing arms. A pair of beam reinforcements are fixedly attached with the trailing arms and with the base of the twist beam. The beam reinforcements are fixedly attached with the twist beam through at least one of fasteners, adhesives, resistance spot welding, cold metal transfer welding, laser welding, and brazing.

A vehicle suspension system having a twist beam axle including a crossbeam and two trailing arms connected thereto. The rear ends of each trailing arm, in the motor vehicle longitudinal direction, having with a wheel mount for fastening a motor vehicle wheel. The front ends of each trailing arm connected via a bearing to the motor vehicle body. Each bearing associated with a MEMS designed as an actuator wherein movements of the bearings and therefore the twist beam axle about the vertical motor vehicle axis can be caused or unfavorable movements of the twist beam axle can be counteracted.

The twist axle assembly includes a pair of spaced apart trailing arms and a twist beam which is made of a single piece and is operably connected with the trailing arms. The twist beam has a top wall, a bottom wall and a pair of side walls. The twist beam presents a pair of end portions which are bent to present edges that face towards one another when viewed in cross-section, and the twist beam presents a middle portion which extends between the end portions. The middle portion has an opening with a generally elliptical shape formed into the bottom wall for reducing a torsion stiffness of the middle portion of the twist beam in comparison to the end portions.

An installation structure of an in-wheel motor unit including a motor, a speed reducer, and a housing, for installing the in-wheel motor unit on a carrier of a suspension apparatus such that the housing is sandwiched by and between the carrier and a bearing unit, wherein the bearing unit and the housing are fastened at first fastening positions, and the carrier and the housing are fastened at second fastening positions the number of which is the same as that of the first fastening positions, wherein each first fastening position and the corresponding second fastening position form a pair, so as to provide a plurality of fastening-position pairs, and wherein the first and second fastening positions of each pair are located at the same position or located close to each other when viewed in a wheel axis direction which is a direction in which a rotation axis of a wheel extends.

A projection of burr is provided by forming an appropriate gap to set a cast-in member to a cast-in mold, completely closing the gap when the cast-in mold is clamped, and correcting cast-in positioning (axis mating) to a die-cast component by a clamping operation of the die-cast mold, regardless of a dimensional precision of the cast-in member upon a manufacture. Steel plate cast-in member 2, wrapped cast except for a bonding portion 2b to a steel plate bonding member 3 upon molding a die-cast component 1, has a mold contact portion 4 at a boundary between a cast-in portion 2a wrapped cast with a die-cast component 1 and the bonding portion 2b. When a cast-in mold A is clamped, the mold contact portion 4 is brought into butting contact with the cast-in mold A, gap S between the cast-in member 2 and the cast-in mold A, cavity a, is closed.

The twist axle assembly includes a twist beam which is made of a single integral piece, extends along a length between opposite ends and the twist beam has an open cross-sectional shape between the ends. The twist beam is stamped into a U-shape with a middle section that extends in a first direction between a pair of trailing arm sections. The trailing arm sections extend at least partially in a second direction that is generally transverse to the first direction to reduce twisting stresses within the trailing arm portions during operation of the twist axle assembly.

This torsion beam manufacturing method is a method of manufacturing a torsion beam that includes a uniformly shaped closed cross-sectional portion of which a cross section orthogonal to a longitudinal direction is a closed cross section having a substantial V-shape or a substantial U-shape at any position in the longitudinal direction, and a shape changing portion which has a connection region leading to the uniformly shaped closed cross-sectional portion and including a closed cross section having a shape different from the shape of the closed cross section of the uniformly shaped closed cross-sectional portion. The torsion beam manufacturing method includes pulling process of applying a tensile force in the longitudinal direction to at least the connection region of a torsion beam material including the uniformly shaped closed cross-sectional portion and the shape changing portion, to obtain the torsion beam.
