An in-wheel motor drive unit (11) includes: a motor portion (11A) that is placed on one side in the direction of the axis of the in-wheel motor drive unit; a wheel hub portion (11C) that is placed on the other side in the direction of the axis of the in-wheel motor drive unit; a speed reduction portion (11B) that is placed between the motor portion and the wheel hub portion and that reduces the speed of output rotation of the motor portion to transmit the resultant output rotation to the wheel hub portion; and a first arm portion (34) that is formed integrally with a speed reduction portion casing (33) forming the outer shape of the speed reduction portion, that projects in a direction perpendicular to the axis from the speed reduction portion casing, and that has its tip end pivotally coupled to a vehicle body-side member.

A suspension structure of a utility vehicle includes a frame, a wheel, and a trailing arm including an arm extending anteroposteriorly and supported by the frame, a knuckle rotatably supporting the wheel, and a rotary shaft configured to angularly displace the knuckle in a vehicle width direction with respect to the arm.

A swing arm type suspension for a rear wheel of an off road vehicle can use two or three tie rods to control toe-in of the knuckle. The rear end of the swing arm is split between an upper clamping arm and a lower clamping arm defining an eye, with the knuckle connected to the upper and lower clamping arms by joint bearings, and with either the transmission shaft or one of the tie rods extending through the eye of the swing arm to the knuckle. The front of the swing arm can be connected to the vehicle frame using a cross-shaft joint. Camber, toe-in and half-track width are controlled to result in a smaller turning radius with better ride characteristics.

A vehicle has a frame, driver and passenger seats, two front and two rear suspension assemblies, two front and two rear wheels, and a motor operatively connected to the at least two wheels. Each rear suspension assembly has a trailing arm having a front end pivotally connected to the frame; a knuckle pivotally connected to a rear portion of the trailing arm; a lower link having a laterally outward end pivotally connected to the trailing arm and a laterally inward end pivotally connected to the frame; an upper link having a laterally outward end pivotally connected to the trailing arm and a laterally inward end pivotally connected to the frame; and a toe link having a laterally outward end pivotally connected to the knuckle and a laterally inward end pivotally connected to the frame.

A vehicle may include a CVT unit or a power source which requires ambient air. An air inlet for an air intake system coupled to the CVT unit or the power source which requires ambient air may be provided in a side of a cargo carrying portion of the vehicle. The vehicle may include a rear radius arm suspension.

A suspension assembly for a vehicle modified to transport an individual using a wheelchair. The modified vehicle includes a lowered floor having an inclined portion to accommodate a ramp. The suspension replaces a portion of the suspension of an original equipment manufactured vehicle to accommodate the lowered floor, which is lowered from the original floor and which includes a width not found in the original floor. The suspension assembly includes a left bushing arm and a right bushing arm operatively connected together by a front and a rear crossmembers. Vehicle frame mounts, coil spring locations, and shock absorber locations are maintained, while accommodating the depth and width of the lowered floor. The additional weight of the vehicle, due to the addition of the lowered floor and anticipated weight of wheelchaired individuals, is accommodated by the suspension to maintain rider comfort.

A utility vehicle includes a rear suspension assembly which has a trailing arm generally extending longitudinally. Also, the rear suspension assembly includes an upper radius rod extending in a generally lateral direction relative to a centerline of the vehicle. Additionally, the rear suspension assembly includes a lower radius rod extending in a generally lateral direction relative to the centerline of the vehicle. The rear suspension assembly further includes a suspension member configured to control toe of the at least one rear ground-engaging member.

A vehicle may include a CVT unit or a power source which requires ambient air. An air inlet for an air intake system coupled to the CVT unit or the power source which requires ambient air may be provided in a side of a cargo carrying portion of the vehicle. The vehicle may include a rear radius arm suspension.

In one embodiment, there is disclosed a modular, blast resistant suspension module for an armored vehicle. Each suspension module has a first and second axle assembly. The first axle assembly has a Short-Long Arm (SLA) suspension system pivotally connected to a blast resistant differential housing and the second axle assembly has a Road Arm (RA) suspension system pivotally connected to the differential housing. The suspension modules may be used to form 44 or 88 vehicle configurations.

The present invention relates to all terrain vehicles having at least a pair of laterally spaced apart seating surfaces.
