An independent suspension system for a vehicle includes: a steering unit configured to be controlled to adjust the steering angle of a wheel, a shock absorber engaged with the wheel and configured to absorb impacts applied to the wheel and including a first shock absorber and a second shock absorber, each of which arranged in a forward-rearward direction on opposite side surfaces of the wheel, and a link unit disposed between the shock absorber and the steering unit in order to vary the distance between the wheel and the steering unit. The link unit includes a first upper arm disposed between the first shock absorber and the steering unit, a second upper arm disposed between the second shock absorber and the steering unit, and at least one ground clearance adjustment unit engaged with the first and second upper arms in order to vary the distance between the first and second upper arms.

A vehicle is provided. The vehicle includes: a chassis including a chassis body and chassis modular units; at least one driving unit arranged in at least one of the chassis modular units, and configured to provide a driving force to at least a pair of wheels; and suspension systems. The chassis body is of an elongate shape in a first direction of the vehicle. A cockpit is arranged in the chassis body. The chassis modular units are connected to the chassis body in series in the first direction, and arranged at first and second ends of the chassis body in the first direction. Each chassis modular unit is connected to a corresponding pair of wheels through a corresponding suspension system.

A tag axle system for a concrete mixing vehicle including an axle including a right wheel assembly and a left wheel assembly, an actuator coupled to the axle to move the axle between a raised position and a lowered position relative to a vehicle chassis, a stabilizer mount plate structured to be coupled to the vehicle chassis, a stabilizer bar rotationally coupled to the stabilizer mount plate, a right stabilizer bar arm rigidly coupled to the stabilizer bar and coupled to the right wheel assembly, and a left stabilizer bar arm rigidly coupled to the stabilizer bar and coupled to the left wheel assembly.

A shock absorber includes a first end fitting connected to a first telescoping member, a second end fitting connected to a second telescoping member, the first and second telescoping members being telescopically mounted relative to each other. An elastomeric spring/damper is disposed between the first telescoping member and the second telescoping member.

A suspension and traction system (MC) is described for vehicles equipped with a frame and a propulsive element (R), which by rolling on the ground (T) is adapted to move the vehicle relative to the ground (T). A rotary electric motor (12) operates two rotors (14, 16) independently controllable from one another to supply two epicycloidal mechanisms (20, 30) whose outer ring gears (28, 38) are independently movable to rotate about the respective solar gear (24, 34) and rigidly connected substantially to a same point (P) of the frame.

A method for predicting mechanical failure of a traction motor in a vehicle includes monitoring first characteristics of an electrical signal supplied to a traction motor of a vehicle during a first detection window. The first characteristics represent a first motor electrical signature for the traction motor. The method also includes deriving one or more signature values from a first mathematical model of the first motor electrical signature and predicting a mechanical failure of the traction motor based on the one or more signature values.
