  • Patent number: 11241927
    Abstract: 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.

  • Publication number: 20210300141
    Abstract: A vehicle has left and right suspension arms operatively connecting left and right ground-engaging members to the vehicle's frame. An anti-roll bar assembly operatively connects the left and right suspension arms. The anti-roll bar assembly includes: an anti-roll bar having left and right end portions operatively connected to the left and right suspension arms, and at least one anti-roll bar connection assembly connecting a middle portion of the anti-roll bar to the frame. Each of the at least one anti-roll bar connection assembly includes: an elastomeric insert mounted to the anti-roll bar, the elastomeric insert engaging the anti-roll bar such that an inner surface of the elastomeric insert rotates together with the anti-roll bar; and a mounting bracket connected to the frame and at least partly enclosing the elastomeric insert, an outer surface of the elastomeric insert being rotatably fixed relative to the mounting bracket.

  • Patent number: 10850582
    Abstract: 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.

  • Patent number: 8714293
    Abstract: 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.
