Suspension assembly including a body associable to the chassis of the tilting vehicle and two junction devices opposite with respect to the body; the junction devices being articulated to the body by means of connecting elements, wherein each junction device includes a first structural junction portion rotationally coupled in a first coupling site to a first connecting element and a second structural joint portion rotationally coupled in a second coupling site to a second connecting element; and wherein the suspension assembly further includes elasto-damping elements associated with the hinge devices and adapted to damp the stresses transmitted by the wheels; and wherein each hinge device includes a dynamic junction portion rotationally coupled to a elasto-damping element in a dynamic junction coupling site; and wherein the junction device rigidly determines the relative positioning and spatial orientation of the first structural joint portion, the second structural joint portion and the dynamic joint portion; ; the suspension assembly further having a rocker arm element associated in a titling manner to the body and to the elasto-damping elements.

A damper includes a damper tube (a pressure tube or a reserve tube for a mono-tube or a double tube damper respectively) including a first end and a second end opposite to the first end. The damper includes a base member. The base member includes a cup portion at least partially enclosing the first end of the damper tube, and a sleeve portion extending from and integral with the cup portion. The sleeve portion surrounds a length of the damper tube. The sleeve portion is attached to the damper tube. Further, the damper includes a knuckle engaged with the sleeve portion such that the sleeve portion is disposed between the knuckle and the damper tube.

A leading-edge steering system is provided for a front suspension of an off-road vehicle. The leading-edge steering system is comprised of a spindle assembly that supports a drive axle assembly to conduct torque from a transaxle to a front wheel. A first rod-end joint pivotally couples an upper suspension arm and the spindle assembly, and a second rod-end joint pivotally couples a lower suspension arm and the spindle assembly. A steering rod-end joint pivotally couples a first end of a steering rod with a leading-edge portion of the spindle assembly. A steering gear is coupled with a second end of the steering rod and configured to move the steering rod, such that the spindle assembly rotates with respect to the upper and lower suspension arms. The leading-edge portion is configured to exert primarily tensile forces on the steering rod during travel over rough terrain.

A suspension system for a rear axle of a vehicle provided with a frame equipped with at least two side members, the suspension system connecting the axle to said side members and comprising a left side and a right side, each comprising an axle-holder assembly, a bellows, a leaf spring, first and second bars, and a torsion bar interposed between said left and right sides. The aforementioned elements of the suspension system being arranged to provide a functional layout having reduced costs and overall dimensions.

Multi-link suspension systems for vehicles are described having various linkages or links that connect to distinct points of a wheel mount or knuckle. Each of the linkages are preferably coupled to the wheel mount via a spherical ball joint and mounted such that they can independently move or rotate with respect to the other linkages. A shock assembly is preferably mounted between two of the linkages on a separate link and is rotatably mounted to each of the two linkages.

An embodiment suspension structure includes a rail housing configured to be installed in a vehicle body along a height direction of the vehicle body, a rail attached to the rail housing toward an outer side of the vehicle body, a plurality of variable position links configured to be moved in the height direction of the vehicle body by engaging with the rail, a link transfer screw threaded to the plurality of variable position links and disposed in parallel with the rail to allow the plurality of variable position links to move by rotation, and a screw motor fixed to an upper inner side of the rail housing and coupled to one end of the link transfer screw, the screw motor being configured to provide a driving force to rotate the link transfer screw.

A method for creating a roller spring perch has steps for making a steel frame bracket, procuring snap rings, procuring four bearings, machining a steel cylindrical bearing housing, machining a bearing shaft, assembling the bearing shaft to the bearing housing with the four bearings pressed onto each of two bearing lands, assembling the snap rings in snap ring grooves of the bearing shaft, placing the bearing housing with the bearing shaft and bearings centered through holes in sidewalls of the steel bracket; and spot welding the bearing housing to the sidewalls of the steel bracket.

A modular axle clamp and riser system for use in a suspension system, which includes a top mount having a substantially flat upper surface, a top mount body which extends transversely to the flat upper surface, a pair of opposing ears which extend from the top mount body, and at least one top mount tooth extending from the top mount body in a direction opposite the ears. Also included is a wedge with at least one wedge tooth which matingly engages the at least one top mount tooth, a wedge upper surface, and a pinion angle surface. Further, the wedge defines a pinion angle between the wedge upper surface and the pinion angle surface. Moreover, an axle mount with at least one axle mount tooth which matingly engages at least one of the at least one top mount tooth and the at least one wedge tooth is provided.

A vehicle knuckle 1 includes a main body 10, a strut junction 11 that is positioned at a first side in an extending direction of an axle supported by the main body and fastens a strut damper, and an arm 12 that couples the main body to the strut junction. The vehicle knuckle has a continuous space 17 formed inside the strut junction and the arm. The arm has a first through-hole 17a on a wall 12a that couples an end 10d at the first side of the main body to the strut junction. The first through-hole is formed, with being adjacent to the end at the first side, at the side of the main body with respect to the center of a coupling position of the wall and the main body and a coupling position of the wall and the strut junction and is communicated with the space.
