A vehicle has a frame, seats, front and rear suspension assemblies, front and rear wheels, a motor, a rear differential, left and right constant velocity joints operatively connected to the rear differential; and left and right half-shaft operatively connecting the constant velocity joints to the rear wheels. Each of the rear suspension assemblies 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; lower and upper links pivotally connected between the trailing arm and the frame; and a toe link pivotally connected between the knuckle and the frame. Each of the rear suspension assemblies has an instant center axis passing through a connection between the trailing arm and the frame. Centers of the velocity joints are laterally outward of their corresponding instant center axes when viewed in a top plan view of the vehicle.

Rear suspension assembly for an off-road vehicle

A vehicle has a frame, seats, two front and two rear suspension assemblies, two front and two rear wheels, and a motor. Each rear suspension assembly has a trailing arm, a knuckle pivotally connected to the trailing arm, a lower link having laterally outward and inward ends pivotally connected to the trailing arm at a first connection point and to the frame at a second connection point respectively, an upper link having laterally outward and inward ends pivotally connected to the trailing arm at a third connection point and to the frame at a fourth connection point respectively, and a toe link having laterally outward an inward ends pivotally connected to the knuckle at a fifth connection point and to the frame at a sixth connection point respectively. The fifth connection point is laterally further from a longitudinally and vertically extending center plane than the first and third connection points.

A vehicle has a frame, a motor, a driveshaft operatively connected to the motor, a front differential operatively connected to the driveshaft, a pair of front half-shafts operatively connecting the front differential to front wheels, at least one rear wheel, a steering wheel, a steering column operatively connected to the steering wheel, a rack and pinion assembly operatively connected to the steering column, the rack and pinion assembly being disposed rearward of the front differential, a right tie rod having a left end operatively connected to a rack of the rack and pinion assembly and a right end operatively connected to the right wheel, and a left tie rod having a right end operatively connected to the rack and a left end operatively connected to the left wheel. The inner ends of the tie rods are disposed forwardly of a vertically and laterally extending central plane of the rack.

Rack and pinion steering system

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 at least two of the 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 link having a laterally outward end pivotally connected to the trailing arm and the knuckle and a laterally inward end pivotally connected to the frame, and a fastener fastening the laterally outward end of the link, the knuckle and the trailing arm together.

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 constant velocity joint includes an outer housing and an inner race disposed inside the outer housing and spaced therefrom. The outer housing and inner race are respectively rotatable about a first and second rotation axes, and moveable relative to one another to change an angle between the rotation axes. A cage, disposed between the outer housing and the inner race, has cage windows defined therethrough. A plurality of balls, each retained in a corresponding cage window roll along corresponding outer housing grooves and inner race grooves, respectively defined on an inner surface of the outer housing and an outer surface of the inner race. Rotation of one of the outer housing and the inner race about their respective rotation axis, causes rotation of the other. A cooling member disposed on the outer housing contacts at least a portion of its outer surface. Powertrains and vehicles are also disclosed.
