Abstract: A linear actuator for vehicle power steering systems with at least three steered wheels of a double-acting type that comprises a cylindrical body, closed at opposite ends; a piston, accommodated inside the cylindrical body axially slideable between the ends; and a stem, rigidly associated with the piston, coaxial to the cylindrical body, and protruding from at least one of the ends, the piston dividing the cylindrical body into two chambers, each provided with an inflow/outflow opening formed at the two opposite ends; and at least one pair of one-way valves, provided in the piston with a respective inlet connected to a respective chamber and outlets mutually connected, each valve having a stem slideably accommodated in the respective inlet with one end associated with a respective flow control element and the opposite end that protrudes externally from the piston, so as to open a respective valve.

Abstract: A drive assembly for actuating wheels of vehicles, particularly carriages for handling and conveying materials, comprising a motor having a substantially vertical driving shaft, a unit for reducing the rotation rate of a driven shaft, which is substantially parallel to the driving shaft, with respect to the rotation rate of the driving shaft, and an angle drive, which is suitable to transmit the motion from the driven shaft to a shaft which is substantially perpendicular thereto for fixing a wheel of a vehicle, and a braking device, which acts on the driving shaft and is interposed between the motor and the reduction unit.

Abstract: A motor wheel for driving the driving wheel of an industrial vehicle and the like, comprising upstream of a two-stage rotary-ring reduction unit, a gearbox with fixed-ring epicyclic gear train, with at least two positions which respectively correspond to the high or travel speed and to the low or working speed. A parking brake is further provided downstream of the gearbox with respect to the motion input.

Abstract: An axle is disclosed which comprises a beam designed for conventional installation on the load-bearing structure of a vehicle, and has, journalled on its opposite ends, road wheel hubs subject to be steered through a steering actuator and being interlinked by a bevel-gear steering drive, such that their relative angular movements can be synchronized to suit pre-determined transmission parameters; the steering actuator is fully supported on the beam and has a stationary part which is rigid with the beam and independent of the load-bearing structure of the vehicle and a moveable part which is connected to the wheel hubs through the steering drive.

Abstract: A steering axle includes a beam pivotally mounted on a load-bearing structure of a vehicle. A steering actuator is mounted on the beam and includes a casing which provides a journal formation for pivotally mounting the beam on the load-bearing structure.

Abstract: An adjustable gauge steering axle is disclosed which comprises an adjustable length beam and a steering control including a double-acting, dual piston rod hydraulic cylinder. Each piston rod of the hydraulic cylinder is connected to a corresponding steering arm through a respective strut which is adjustable telescopingly in length; a swivel joint intervenes between the rod and the strut.
