A steering axle (20) for a steerable vehicle includes an axle housing (1), a first steering knuckle (4), a second steering knuckle (5), a steering motor (6), and a steering gear (16). The first steering knuckle (4) and the second steering knuckle (5) are mounted so as to be steerable in the axle housing (1). The steering axle (20) has a first flexible drive (21) that connects a first output (12) of the steering gear (16) to the first steering knuckle (4) in terms of drive, and a second flexible drive (22) that connects a second output (13) of the steering gear (16) to the second steering knuckle (5) in terms of drive, so that a rotational speed of the steering motor (6) results in a steering movement of the first steering knuckle (4) and of the second steering knuckle (5). Also disclosed is a corresponding industrial truck.

A steering system for a vehicle includes a drive motor having a motor shaft. The steering system also includes a first gear reduction stage for receiving a first rotational input from the motor shaft and providing a first rotational output. The steering system further includes a second gear reduction stage for receiving the first rotational output from the first gear reduction stage and providing a second rotational output. The second gear reduction stage may include at least one of a strain wave gearing, a worm drive, and a planetary gearing. The steering system includes an output shaft for receiving the second rotational output from the second gear reduction stage.

A steering assembly for a lawn maintenance vehicle having a control assembly that receives a user rotational input, a transfer assembly for transferring the rotational input from the user to a pair of wheel assemblies. Each wheel assembly includes a knuckle connected to a pivot bar by way of a kingpin, wherein the kingpin is positioned within the rim of the tire operatively connected to the knuckle. The transfer assembly includes a sector gear having a leading edge that forms a rack that is meshingly engaged to a pinion gear of the transfer assembly.

A wheel suspension includes an axle limb which supports a wheel. The axle limb includes a first steering axle which provides a first steering angle in a specified range for the wheel, and components for connecting the axle limb to a support structure. At least one of the components includes a second steering axle which is selectively releasable in order to provide a steering angle which is different than the first steering axle. The components for connecting the axle limb to the support structure form a McPherson suspension.

A motor vehicle with driving and steering rear wheels—comprises includes a rear suspension system having a support frame mounted on the vehicle body. For each rear wheel, a wheel support is connected to the frame by oscillating arms. An actuator is mounted on the frame, with control rods, protruding from opposite ends of the actuator body, and connected to the wheel supports by control arms. Within a space between the rear wheels, there is a rear motor or differential. The actuator body is mounted on the frame along a transverse direction spaced apart from an axis of the rear wheels to avoid interference with the motor or differential. The control arms are substantially parallel to a transverse direction perpendicular to the longitudinal direction, or form an angle therewith not exceeding 15 degrees. The control rods are connected to the control arms with the interposition of a transmission.
