Methods and systems are provided for an electric heavy-duty vehicle. In one example, a system for the vehicle may include a wheel hub assembly coupled to a frame of the vehicle via a first wishbone arm and a second wishbone arm, and an air spring coupled at opposite ends to a first link and a second link, each of the first link and the second link being pivotably coupled to the frame of the vehicle, the second link further being pivotably coupled to the first wishbone arm. The air spring may be positioned above the wheel hub assembly with respect to the vehicle.

A toe link support is disclosed. In a first aspect, the toe link aperture of a hub has been bored out to receive inner and outer spacers. The spacers have bolt holes through which a toe link bolt is inserted to secure a toe link to the hub. The bolt is secured by a nut. The spacers protect the hub from damage by the bolt, and vice versa, resulting from motion of the toe link. In a second aspect, the outer spacer is further configured to be inserted into the bolt hole of the toe link, further protecting the bolt from damage. A method of supporting a toe link is also disclosed.

A hanger for axle/suspension systems of a heavy-duty vehicle includes an outboard wall spaced apart from an inboard wall. The outboard wall is connected to the inboard wall via a front wall. The outboard wall and the inboard wall are formed with an aligned opening extending through the outboard wall and the inboard wall. A top plate connected to the inboard wall, the outboard wall and the front wall. The top plate is formed with at least one circular opening or laterally oriented oblong-round opening and at least one laterally slotted opening. A fastener is disposed through the at least one circular opening or oblong-round opening. A second fastener is disposed through the at least one laterally slotted opening for mounting the hanger to a frame of the heavy-duty vehicle.

A vehicle suspension system includes left and right control arm assemblies each having a wheel mount structure, an upper control arm, and a lower control arm. Each control arm includes a first end configured to be pivotably connected to a frame structure of a vehicle and a second end rotatably connected to the wheel mount structure. The vehicle suspension system also includes a transverse leaf spring having an elongated body extending between the control arm assemblies, outer mounting brackets respectively connecting left and right ends of the elongated body to the left and right control arm assemblies, and one or more inner mounting brackets located between the outer mounting brackets. The transverse leaf spring is contoured such that a contoured portion of the elongated body deviates in a downward direction in order to extend below an electric drive system disposed within an internal space between rails of the frame structure.

The disclosure relates to the technical field of vehicles, and particularly provides a multi-link independent suspension for a vehicle that includes a subframe and a steering knuckle. In order to solve the problem of reduced adjustment efficiency caused by mutual restraining of linkages of an existing multi-link independent suspension when a camber angle is adjusted, the multi-link independent suspension includes a spring control arm that is configured to adjust a camber angle of a wheel center. The multi-link independent suspension also includes a front upper control arm and a rear upper control arm. A central axis of the front upper control arm intersects with a central axis of the rear upper control arm at a Q point, and the Q point has the same coordinate as the wheel center in an X direction; and a motion centerline between the front upper control arm and the rear upper control arm coincides with a projection of a central axis of the spring control arm on an XY plane, so that a movement of the spring control arm has no effect on an upper control arm system when the camber angle is being adjusted. The steering knuckle only rotates about an X axis so as to drive a tire to rotate about the X axis, so that a camber angle of the tire can be adjusted without changing a toe-in angle, thereby reducing the number of affected linkages and simplifying the adjustment in the camber angle of the tire.

A bush including an inner cylinder, an outer cylinder arranged radially outside the inner cylinder, and an elastic body connecting the inner cylinder and the outer cylinder, where a rubber portion 13 is provided with a bore (low-rigidity portion) 14 that extends a predetermined length in a circumferential direction and lowers rigidity in a radial direction, a convex portion 11a that projects from the inner cylinder 11 to the outer cylinder 12 is provided at a circumferential position corresponding to the bore 14 of the inner cylinder 11, and the convex portion 11a is arranged to be shifted to one side in the circumferential direction with respect to a circumferential center of the bore 14.

A structural arrangement for a vehicle includes a vehicle frame including a first frame member and a second frame member coupled to the first frame member. The vehicle frame extends along a vehicle body axis. The vehicle frame includes a suspension component including a control arm, a bushing, a bolt coupling the suspension component to the second frame member, and a load member coupled to the first frame member at a first attachment point and coupled to the second frame member at a second attachment point. The load member extends generally longitudinally along the vehicle body axis. The suspension component is coupled to the second frame member at the second attachment point and is detachable from the second frame member upon application of a load to the vehicle due to an impact event.

An axle tie rod adapted to be secured to an axle tube of a utility vehicle includes a connecting element and at least one link element, wherein the connecting element has a first connecting section in which a welded connection with the link element can be produced, wherein the connecting element has a second connecting section in which a welded connection with an axle tube can be produced, and wherein the second connecting section is configured to engage around the axle tube.

A joint realizing higher rigidity without increasing the wall thickness provided with a base part 12, a pair of side parts 14, 14 extending from the two end parts of the base part 12 in the first direction D1 to the same side in the second direction D2 vertical to the first direction D1, the pair of side parts 14, 14 being formed with fastening holes 14H at the center in a third direction D3 vertical to both the first direction D1 and second direction D2, and a closed part 16 formed between the pair of side parts 14, 14 as an extended region of the base part 12 and pair of side parts 14, 14 at least at one end in the third direction D3.

Embodiments of the present invention describe a recreational vehicle spindle, including a spindle body having one or more sockets in the spindle body, and an upper attachment mechanism in contact with the spindle body and adapted to attach to a steering component. The spindle also includes a lower attachment mechanism in contact with the spindle body and adapted to attach to a ski or wheel. The one or more sockets are adapted to each receive a ball and stud forming one or more ball joints.
