A wheel suspension and transmission gear assembly may include: a main arm pivotally connectable at a connection point of the main arm to a shaft point of a wheel; a first linkage unit pivotally connected at its first end to the main arm; and a second linkage unit pivotally connected at its first end to the main arm such that at least a portion of the main arm is between the first linkage unit and the second linkage unit and such that a second end of the first linkage unit and a second end of the second linkage unit are at opposing sides of the main arm with respect to each other; wherein (i) the main arm and (ii) the first linkage unit or the second linkage unit each may include: a first gear and a second gear pivotally connected thereto and interconnected to transmit rotational motion between each other.

A frame and suspension assembly for a vehicle can include a pair of frame members configured to support a load input thereto, a final drive structure connected to each of the frame members such that the final drive assembly is configured to input a load to the frame members, and a stabilizer bar mounted to each of the frame members and extending in a traverse direction of the vehicle over a top of the final drive structure.

A suspension includes a housing, links, a radius arm, and a radius arm bush. The radius arm bush is provided on a front end of the radius arm, couples the radius arm to a vehicle body, with an elastic body in between, and is disposed vehicle-widthwise inwardly of a wheel center contact point of the rear wheel. The radius arm bush has higher rigidity with respect to turn of the radius arm with respect to the vehicle body in a direction in which an underside of the radius arm is displaced vehicle-widthwise outwardly from an upside of the radius arm, than rigidity with respect to turn of the radius arm with respect to the vehicle body in a direction in which the underside of the radius arm is displaced vehicle-widthwise inwardly from the upside of the radius arm.

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 device includes knuckles that rotatably retain rear wheels, an electric actuator that steers the rear wheels, paired tie rods that are connected to the electric actuator via a link mechanism and driven back and forth by the electric actuator, brackets that are rotated by the tie rods, and a lower arm attached to the brackets. Each bracket is rotatable between the knuckle and the lower arm.

A trailing link multi-bar suspension assembly for a cycle having improved stability includes a first arm having a first arm fixed pivot and a first arm shock pivot. A shock link has a shock link fixed pivot and a shock link floating pivot. A shock absorber has an inline configuration, a gas spring, a first shock mount, and a second shock mount. A wheel carrier has a wheel carrier first pivot and a wheel carrier second pivot spaced apart from one another, and a wheel mount that is adapted to be connected to a wheel. A control link has a control link floating pivot and a control link fixed pivot, the control link floating pivot being pivotably connected to the wheel carrier second pivot, and the control link fixed pivot being pivotably connected to the first arm control pivot.

A wheel suspension for a motor vehicle, including a wheel carrier (2) for holding a wheel (3), a wheel-guiding control arm (4) for articulating the wheel carrier (2) to a structure, and steering member (23) for steering the wheel (3). For steering the wheel (3), the wheel carrier (2) and the wheel-guiding control arm (4) are articulated to one another in such manner that the wheel carrier (2) can pivot relative to the wheel-guiding control arm (4) about a steering axis. The wheel carrier (2) is connected indirectly to the control arm (4) in a first connection zone (20) by an integral link (5).
