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).

A two-wheeled vehicle includes a frame assembly, a plurality of ground-engaging members for supporting the frame assembly, and a cooling assembly positioned below a head portion of the frame assembly and intermediate vertically-extending frame tubes of the frame assembly. A lower end of the cooling assembly is coupled to a lower end of the vertically-extending frame tubes, and an upper end of the cooling assembly is frictionally retained at an upper end of each of the vertically-extending frame tubes.

Embodiments relate to an off-road vehicle comprising a frame, including at least one cargo box support member, a suspension movably coupled to the frame, a passenger compartment, an engine, a transmission operatively coupled to the engine, and a cargo box. The cargo box includes a floor and a plurality of upwardly extending sidewalls, wherein at least a portion of the cargo box floor extends over the at least one cargo box support member and wherein the cargo box is removably coupled to the at least one cargo box support members and is removable from the off-road vehicle via the removal of fewer than eight fasteners.

A universal joint includes: a housing; an arm, part of which is located inside the housing; an external bush that is located between an inner circumferential surface of the housing and the arm; an internal bush that is located on the opposite side of the external bush with the arm being interposed therebetween; and a supporting member that supports the internal bush. The arm includes: an arm convex surface that is a spherical convex surface; and an arm concave surface that is a spherical concave surface. The external bush includes a bush concave surface that is a spherical concave surface in contact with the arm convex surface. The internal bush includes a bush convex surface that is a spherical convex surface in contact with the arm concave surface.

An off-road vehicle includes a frame, a front suspension, and a rear suspension. In some examples of the off-road vehicle, the rear suspension includes trailing arms with are pivotally attached to the frame rearward of an operator area. Further, the frame can include a front subframe assembly and a rear subframe assembly which are easily removable from the main frame of the vehicle to permit access to various components of the off-road 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 supplemental turning function-equipped hub unit includes: a hub unit body including a hub bearing; and a unit support member configured to be mounted through a suspension device, the unit support member supporting the hub unit body through rotation-permitting support components at two upper and lower portions of the hub unit body such that the hub unit body is rotatable about a supplemental turning axis. A supplemental turning force receiving part is provided on a side part of the hub unit body, which part is configured to receive a force that causes the hub unit body to rotate about the supplemental turning axis.

Embodiments relate to an off-road vehicle comprising a frame, including at least one cargo box support member, a suspension movably coupled to the frame, a passenger compartment, an engine, a transmission operatively coupled to the engine, and a cargo box. The cargo box includes a floor and a plurality of upwardly extending sidewalls, wherein at least a portion of the cargo box floor extends over the at least one cargo box support member and wherein the cargo box is removably coupled to the at least one cargo box support members and is removable from the off-road vehicle via the removal of fewer than eight fasteners.

An electric vehicle has a structure mounted on balls which are arranged for rolling on the ground, wherein an actuating roller is associated with each ball. The roller-supporting structure is rotatably mounted about a substantially vertical axis within a main supporting structure which is rigidly connected to the ball-supporting member. The main support structure carries a first electric motor for controlling the rotation of the roller-supporting structure about the substantially vertical axis, while the roller-supporting structure carries a second electric motor for controlling the rotation of the roller about its axis.

A trailer includes a trailer frame having a hitch. A stationary support base is joined to the trailer frame. Two support plates are slidably guided on the support base toward and away from each other. A pair of wheel assemblies is provided, wherein a wheel assembly is mounted to an end of each of the support plates remote from the other support plate such that a distance between the wheel assemblies varies with movement of the support plates on the support base. A pair of drive links is provided wherein a drive link is joined to each of the support plates. A drive mechanism is joined to the drive links and configured to selectively move the support plates toward or away from each other.
