The vehicle comprises at least one door that provides ingress and egress to the interior of the cabin of the vehicle. The vehicle comprises a windshield that provides a visual line of sight out of the cabin for a user located within the interior of the cabin, and wherein the windshield extends across the front and at least partially on to at least one of the first side or the second side.

A bushing includes a body that is cylindrical; a bore through the body; a channel extending along an inner face of the bore; and a groove on a substantially planar surface of the bushing and including a first end intersecting with an end of the channel and a second end extending radially from the bore.

A rod-end front suspension is provided for an off-road vehicle. The rod-end front suspension comprises a spindle assembly that is pivotally coupled with an upper suspension arm by way of a first rod-end joint and pivotally coupled with a lower suspension arm by way of a second rod-end joint. A steering rod-end joint coupled with the spindle assembly pivotally receives a steering rod. An axle assembly coupled with the spindle assembly conducts torque from a transaxle to a wheel coupled with the spindle assembly. Each of the first and second rod-end joints comprises a ball rotatably retained within a casing. The ball is fastened within a recess between parallel prongs extending from the spindle assembly. A threaded shank extending from the casing is threadably fixated with the suspension arm, such that the spindle assembly may be moved with respect to the casing and the suspension arm.

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 including a Chebyshev-Lambda (CL) mechanism, at least one linear motion mechanism and a spring-damper assembly, the CL mechanism including a suspension-arm, a support-arm and a first rotating-arm, an end of the rotating-arm being configured to be coupled with a reference frame at an anchoring-node, an operational-end of the suspension-arm being configured to be coupled with a suspended-mount at a first node, an end of the support-arm being configured to be coupled with the reference frame at a support-anchoring-node, the linear motion mechanism configured to be coupled with the reference frame via at least one anchoring node, an end of the linear motion mechanism being configured to be coupled with the suspended-mount at a second node, and the spring-damper assembly including at least one spring and at least one damper, wherein respective first and second ends of the spring and the damper are coupled between two points.

A wheel suspension for a vehicle includes: a steering knuckle support; a steering knuckle mounted at the steering knuckle support so as to be swivelable around a steering axis; a vehicle wheel mounted at the steering knuckle so as to be rotatable around a wheel rotational axis; and a plurality of links by which the steering knuckle support is articulated at a vehicle frame such that the steering knuckle support is moveable in a vertical direction of the vehicle relative to the vehicle frame. A first one of the links is configured as a first control arm configured as a four-bar link, and a second one of the links is configured as a second control arm arranged offset relative to the first link in the vertical direction of the vehicle, and wherein the second link is configured as a two-bar link that is adjustable in length.

A suspension includes a housing, suspension links, a spring, and a stabilizer. The housing rotatably supports a rear wheel of a vehicle. The suspension links each have both ends swingably coupled to a vehicle body of the vehicle and the housing. The spring is disposed between the vehicle body and one of the suspension links or the housing. The stabilizer includes a stabilizer bar and a stabilizer link. A force application point where force generated by the spring is applied to the housing is disposed on a rear side of the vehicle with respect to a center of the rear wheel. The stabilizer link is coupled to the housing to allow a force application point where force generated by the stabilizer is applied to the housing to be disposed on the rear side of the vehicle with respect to the center of the rear wheel.

A bushing includes a cylindrical body and a flange extending from the cylindrical body. The cylindrical body has an inner face defining a bore. The flange includes an outer rim and a face extending radially between the bore and the outer rim. At least one groove is formed in the face. The at least one groove extends from a first end intersecting the bore to a second end adjacent the outer rim such that grease supplied to the bore of the bushing is able to flow through the at least one groove.

An adaptive tire traction control system for motor vehicle tires for grip enhancement and rolling friction reduction. The tire surface area is radially divided into multiple zones, in the three zones configuration the tire is composed of an outer shoulder, centre and inner shoulder. The outer shoulder is equipped with a plurality of studs to increase the traction when vehicle is on icy or muddy surfaces. The centre part is made of low friction rubbers for the normal operation to increase fuel economy and lengthen the tires life, and reduced rolling noise. The inner shoulder is equipped with high grip rubber to provide better grip in case of emergency braking. In one embodiment, the tilting mechanism of the tire traction system can be connected to the anti-lock braking system (ABS). In case of emergency braking, the inner shoulder with high grip rubber is brought in contact with the ground to provide more grips.
