A spring seat body for connection to a rigid axle of a motor vehicle, including an upper spring seat surface, a lower seat surface, lateral edge surfaces which lie between the spring seat surface and the lower seat surface, and holding means for holding tensioning means for fastening at least one spring to the spring seat body. The lateral edge surfaces include a first edge surface and a second edge surface which face away from one another and, in the mounted state of the spring seat body on the rigid axle, run transversely with respect to the rigid axle, the first edge surface, in the mounted state of the spring seat body on the rigid axle, lying closer to an end of the rigid axle which bears a vehicle wheel than the second edge surface, and the first edge surface having an edge course which, in the mounted state of the spring seat body on the rigid axle, lies in overlap with the rigid axle. In order for the spring seat body to offer improved robustness, in particular increased fatigue strength in its connection to a generic rigid axle and thereby enable a reduction in the overall weight of the rigid axle, the invention provides that said edge course, viewed from above, is at least partially formed as an outwardly projecting, preferably convex edge course, the apex or vertex lies in a region of the first edge surface which runs along a central length range of the upper spring seat surface running transversely to the rigid axle, said central length range being less than one third, preferably less than one quarter, particularly preferably less than one fifth of the length of the upper spring seat surface. In particular, the invention relates to a rigid axle for a motor vehicle, in particular a utility vehicle, with such a spring seat body.

Systems and apparatuses include a chassis mount configured to couple to a vehicle chassis, an axle assembly including wheels, a four-bar linkage coupling the axle assembly to the chassis mount, and a hydraulic cylinder coupled between the chassis mount and the axle assembly. The hydraulic cylinder actuates the axle assembly between a raised position and a lowered position and acts as a spring damper suspension component.

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 suspension for a two-wheeled vehicle includes first and second fork legs. Each fork leg includes a dropout. Each dropout has an opening therethrough. At least a portion of one of the openings is threaded. Each of the dropouts includes a split-damp pinch bearing defining the opening and operable between an open position and a locked position, and a hand operable actuator pivoted to the bearing for operation thereof. The suspension further includes a one-piece axle. The axle is disposed through the openings. The axle has a threaded first end engaged with the threaded portion. The axle has an ergonomic grip formed at a second end. The bearing tightly engages an outer surface of the axle in the locked position, thereby rotationally coupling the axle to the dropout.

A transmission to transfer case adaptor kit, having a transfer case to convert a two-wheel drive production truck to four-wheel drive enabling a drivetrain that allows all four wheels of the truck to receive torque from an engine of the truck, whereby the truck has a transmission system and is retrofitted with a front axle adaptor kit, and a transfer case parking brake system adaptor kit and support mount.

A front axle adaptor kit, having a front differential assembly, first and second shock absorber brackets, a spring support bracket, a track-bar bracket, and a dampener bracket to convert a two-wheel drive production truck to four-wheel drive enabling a drivetrain that allows all four wheels of the truck to receive torque from an engine of the truck. The truck has a transmission system and is retrofitted with a transmission to transfer case adaptor kit, and a transfer case parking brake system adaptor kit and support mount.

A portal box assembly for mounting a wheel to an off road vehicle in a lifted and extended wheelbase position. The assembly includes a portal gear box having an input shaft opening for an input shaft, and an output shaft extending from an output shaft opening. The portal gear box also includes a set of gears effective to transmit power from the input shaft to the output shaft, and optionally to reduce the gear ratio. The assembly is mountable to the vehicle in an extended wheelbase position in which the output shaft is positioned below and forward of the input shaft when the assembly is used to mount a forward wheel, and in which the output shaft is positioned below and rearward of the input shaft when the assembly is used to mount a rear wheel.

A suspension for a two-wheeled vehicle includes first and second fork legs. Each fork leg includes a dropout. Each dropout has an opening therethrough. At least a portion of one of the openings is threaded. Each of the dropouts includes a split-damp pinch bearing defining the opening and operable between an open position and a locked position, and a hand operable actuator pivoted to the bearing for operation thereof. The suspension further includes a one-piece axle. The axle is disposed through the openings. The axle has a threaded first end engaged with the threaded portion. The axle has an ergonomic grip formed at a second end. The bearing tightly engages an outer surface of the axle in the locked position, thereby rotationally coupling the axle to the dropout.

An axle unit includes an axle tube and a suspension arm element, wherein the axle tube extends substantially along a tube axis, wherein the suspension arm element has a first joining region comprising a recess, wherein the first joining region of the suspension arm element is adjacent to the axle tube, wherein the suspension arm element is substantially transverse to the tube axis, and wherein a weld portion between the suspension arm element and the axle tube is located in the first joining region.

A suspension for a wheeled vehicle include an axle with a mid-section and an end comprising an upper portion and a lower portion defining a space therebetween, a leaf spring having forward and rear ends attached to vehicle structure and a mid-section retained in the space and secured between the upper and lower portions, and a closure element attached to the axle end and at least partially closing an outboard end of the space. The upper and lower axle portions may be formed integrally with the axle mid-section or may be a separately-formed component secured to the axle. The space tapers from a greater vertical dimension at the outboard end thereof to a smaller vertical dimension at an inboard end thereof, and the leaf spring mid-section is wedged into the space. An intermediate element is disposed between the mid-section and at least one of the upper and lower axle portions.
