A wheel suspension includes an axle limb which supports a wheel. The axle limb includes a first steering axle which provides a first steering angle in a specified range for the wheel, and components for connecting the axle limb to a support structure. At least one of the components includes a second steering axle which is selectively releasable in order to provide a steering angle which is different than the first steering axle. The components for connecting the axle limb to the support structure form a McPherson suspension.

A suspension device (rear suspension (10)) for vehicles is provided which includes a damper (40), a shaft (50) pivotably supporting an end of the damper (40), and a bush (60) including a cylindrical elastic member fitted onto the outer circumference of the shaft (50). The axis (C2) of the bush (60) is disposed along a line of intersection between an imaginary first plane (S1) and an imaginary second plane (S2), or along a line parallel to the line of intersection. The first plane (S1) is orthogonal to the axis (C1) of the damper (40) when a stroke position of a wheel (24) is a first position relative to the vehicle body (80) in the vertical direction of a vehicle body (80). The second plane (S2) is orthogonal to the axis (C1) of the damper (40) when the stroke position of the wheel (24) is a second position.

A stabilizer including: a main body for generating an elastic restoring force; and connecting portions formed on both ends of the main body and respectively connected to left and right suspension devices. Hardness of the connecting portions is lower than that of the main body. A method for manufacturing the stabilizer includes, in order, an entire body heat treatment process for heat treating an entire stabilizer and increasing hardness of the entire stabilizer, and a connecting portion softening process for heating the connecting portions and reducing the hardness of the connecting portions. The method for manufacturing the stabilizer thereby increases hardness of the main body and reduces the hardness of the connecting portions lower than that of the main body.

An independent suspension for vehicles, in particular for heavy vehicles, includes a steering knuckle developing between an outer portion, defining the axis of rotation of a wheel hub, and an inner portion, having a receiving seat extending transversely to the outer portion along a steering axis and a knuckle-carrier assembly rotatably coupled to the inner portion of the knuckle to allow a relative rotation around the steering axis, and including at least a first and a second supporting portion defining each a substantially horizontal hinge point for one end of a respective cross arm. The knuckle-carrier assembly includes a first and a second body, separate to each other, in which the first body includes a steering pin developing along the steering axis and the first supporting portion and the second body is partially fitted around the steering pin and includes the second supporting portion.

A RevoKnuckle-type suspension for a wheeled vehicle has a hub mounted to a bearing carrier for rotation relative thereto about a steering axis, and a shock absorber connected non-rotatably to the bearing carrier. The shock absorber has an outer cylinder having an axially-extending guide hole defined therein, and a piston and attached piston rod retained for axial reciprocation in the guide hole. The guide hole and at least one of the piston and the piston rod retained therein have respective complementary-shaped, non-circular cross-sectional shapes which engage one another to resist axial rotation of the piston and/or the piston rod within the guide hole. The carrier is therefore restrained against rotation relative to the vehicle sprung structure without the need for any additional component(s) such as a control arm or stabilizer, as required in a traditional RevoKnuckle-type suspension.

A wheel mount, particularly for the front axle of a motor vehicle, has a basic body that has at least individual ones of the following accommodations or recesses: for accommodation of a kingpin for a wheel bearing, for connection of a brake caliper, for mounting of an upper wishbone fork, for mounting of an upper semi-trailing arm, for mounting of a tie rod, for mounting of a lower spring link, for mounting of a further lower wishbone, for positioning of a sensor, particularly an rpm sensor, for attachment of a sensor, particularly an rpm sensor, wherein the wheel mount is produced as a die-cast component made in one piece with these accommodations or recesses and connecting them with one another, preferably from light metal.

A wheel carrier for a vehicle suspension, intended for the rotatable mounting of a wheel, having a wheel carrier body made of metal is adapted to provide a stable, weight-optimized wheel suspension. The wheel carrier includes a wheel-attachment section and an extension projecting upwardly therefrom with means at its upper end for attaching an inboard-projecting control arm. A portion of the extension is offset inboard relative to the upper end and includes a hybrid section in which the wheel carrier body is reinforced in sections by a reinforcing element made of a fiber composite material.

A bushing may include an elastic compression portion configured to form a primary compression ratio due to a compressive deformation by a primary press-fitting load and be pressed by a secondary compression ratio greater than the primary compression ratio by a secondary press-fitting load greater than the primary press-fitting load, wherein the elastic compression portion is formed in an opened cross section to be a secondary surface contact larger than a primary surface contact without a bulge phenomenon by a volume dispersion in a state in which it is pressed by the primary press-fitting load to be the primary surface contact and then is pressed by the secondary press-fitting load.

A stabilizer including: a main body for generating an elastic restoring force; and connecting portions formed on both ends of the main body and respectively connected to left and right suspension devices. Hardness of the connecting portions is lower than that of the main body. A method for manufacturing the stabilizer includes, in order, an entire body heat treatment process for heat treating an entire stabilizer and increasing hardness of the entire stabilizer, and a connecting portion softening process for heating the connecting portions and reducing the hardness of the connecting portions. The method for manufacturing the stabilizer thereby increases hardness of the main body and reduces the hardness of the connecting portions lower than that of the main body.
