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.

An in-wheel suspension system includes an assembly with a main arm that is pivotally connected at a connection point on the main arm to a shaft point of a wheel, a first linkage unit pivotally connected at one end to a first end of the main arm, and a second linkage unit pivotally connected at one end to a second end of the main arm. At least one second end of the first linkage unit and at least one second end of the second linkage unit, that are not connected to the main arm, are pivotally connectable each to a reference frame at a defined distance between them, such as to form a substantially Z like shape.

An in-wheel suspension system includes an assembly with a main arm that is pivotally connected at a connection point on the main arm to a shaft point of a wheel, a first linkage unit pivotally connected at one end to a first end of the main arm, and a second linkage unit pivotally connected at one end to a second end of the main arm. At least one second end of the first linkage unit and at least one second end of the second linkage unit, that are not connected to the main arm, are pivotally connectable each to a reference frame at a defined distance between them, such as to form a substantially Z like shape.

Provided is a trailing arm riding mower suspension system that includes trailing arms adapted to support hydraulic motor units and having leading ends pivotally coupled to a mower frame by way of leading end spherical joints and trailing ends having hydraulic drive unit mounts, where the trailing arms are adapted to pivot about leading end pivot locations defined by the leading end spherical joints.

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.
