Provided is a work vehicle including a wheel support member including an axle that supports a pair of left and right travel wheels; a link mechanism that is provided spanning between a vehicle body and the wheel support member, and that supports the wheel support member such that the wheel support member can be raised and lowered; and a suspension mechanism that is provided spanning between a suspension support section formed on the vehicle body and the wheel support member, and that elastically supports the wheel support member.

A vehicle suspension assembly includes an axle member, a pair of mounting brackets configured to couple to a vehicle frame, and a trailing arm arrangement that includes a first trailing arm portion having a first end pivotably coupled to one of the pair of mounting brackets, and a second end rotationally coupled with the axle member at a first position, a second trailing arm portion having a second end pivotably coupled to the other of the pair of mounting brackets, and a second end rotationally coupled with the axle member at a second position, and a first torsional member having a first end fixedly coupled to the first trailing arm portion and a second end fixedly secured to the axle member at a third position, the first torsional member configured to transmit torsion of the axle member to the first trailing arm portion.

A suspension joining structure may include a lower arm which has one end portion fastened to a vehicle body, an assist knuckle on which a strut portion is located, a fastening unit which is configured so that a second end portion of the lower arm and a lower end portion of the assist knuckle are fastened, a revoknuckle which is pivotally fastened to the assist knuckle to be rotated independently of the assist knuckle to perform the steering of a wheel, and a steering input portion fastened to the revoknuckle and configured to apply a steering force to the revoknuckle upon the steering of the wheel.

The invention relates to a chassis for a utility vehicle, having a first .sup.J chassis element extending transversely with respect to the vehicle longitudinal direction and a second chassis element (5) fixed to the outer side thereof, wherein the second chassis element (5) is supported against the outer side of the first chassis element via at least one roughened supporting area (11, 12). In order to avoid relative movements between the chassis elements connected by clamping forces in a utility vehicle chassis, the roughening comprises a surface structure produced by machining the supporting area (11, 12) in a blasting process and preferably a laser beam process. The invention further relates to specific individual parts of such a chassis, specifically an axle shell, an axle guide (5), and a brake carrier.

Axle system for use in utility vehicles includes a suspension arm and a clamping unit, wherein the clamping unit has a base element and a clamping element, wherein the base element is substantially arranged on a first side and the clamping element on the second side of the suspension arm lying opposite the first side, wherein the base element is configured to be secured to an axle element, and wherein a tensile element is configured to apply a tensile force between the clamping element and the base element, such that the suspension arm is held by force fit between the clamping element and the base element.

A suspension device according to one embodiment of the present disclosure which is equipped with an upper arm which is supported by a knuckle of the vehicle wheel so as to be capable of oscillation, and also supported by a side member which extends in the vehicle front-rear direction so as to be capable of oscillation, wherein: the upper arm has a tip end section positioned at the outside end in the vehicle widthwise direction, and also has arm sections which fork from the tip end section toward the inside in the vehicle widthwise direction; and the upper arm is formed in a manner such that the cross-sectional area of one arm section is greater than the cross-sectional area of the other arm section.

A vehicle suspension includes at least one anchor bar, at least one axle lift spring, an auxiliary drop-type axle which may be selectively lifted or lowered and a single, integrated support attaching the at least one axle lift spring and the at least one anchor bar to the auxiliary drop-type axle, wherein the single, integrated support provides the only attachment of the at least one axle lift spring and the at least one anchor bar to the auxiliary drop-type axle, and wherein the support includes an open area configured to allow the passage of a cardan.

A wheel suspension for an at least slightly actively steerable has a wheel carrier for receiving a wheel, a toe link, and at least one further link for connecting the wheel carrier to the vehicle body, and an actuator arrangement having at least one actuator for actively steering the wheel in a first active steering direction and in a second active steering direction. The wheel carrier is formed in at least two parts and has a first wheel carrier part and a second wheel carrier part. The first wheel carrier part is designed to receive the wheel and the second wheel carrier part can be attached via at least one of the further links to the vehicle body, in a non-actively steerable manner. The first wheel carrier part and the second wheel carrier part in a functional state of use of the wheel suspension in a vehicle are movable relative to one another by the actuator arrangement, such that an active, at least slight steering movement of the wheel can be effected.

An adjustment device (1) for a chassis of a motor vehicle. The adjustment device has an actuator (2) with a housing (5) and a spindle drive, which has an axially displaceable spindle (10), with a fixed mounting (7) on the vehicle side and a connecting element (4) on the chassis side. The spindle (10) is extended in a direction of its longitudinal axis by an extension piece (11), and the connecting element (4) is attached to the outer end (11b) of the extension piece (11).

An apparatus is described for interconnecting a steering knuckle and lower suspension arm. The apparatus includes a ball joint assembly having a height adjustment feature and a non-concentric ball and shaft that together allow for increased range of camber adjustment.
