VEHICLE HAVING DRIVING AND STEERING WHEELS CARRIED BY LEGS ARTICULATED TO THE VEHICLE STRUCTURE, WITH EACH LEG INCORPORATING A SYSTEM FOR DRIVING AND ORIENTING THE RESPECTIVE WHEEL
20240227484 · 2024-07-11 · ·

A vehicle has steering and drive wheels supported by legs articulated to the structure of the vehicle. Each leg is rotatably mounted on a main support around a transverse axis. The main support is rotatably mounted about the transverse axis on a base structure, which is connected to the structure of the vehicle. An actuator device is operatively interposed between the main support and the base support to adjust the position of the main support around the transverse axis, and consequently the height of the vehicle from the ground. A hub-bearing support carrying the wheel hub is rotatably mounted around a wheel steering axis on an auxiliary camber adjustment support. The latter is carried around a camber adjustment axis on a further auxiliary caster adjustment support. The latter is carried by the leg around a caster adjustment axis. The steering of the wheel and the camber adjustment are controlled by respective actuator devices. The caster adjustment is automatically controlled as the position of the leg changes around the transverse axis.

STEER DRIVE WHEEL MECHANISM
20240278640 · 2024-08-22 · ·

The disclosed invention introduces a steer-drive wheel mechanism, suitable for applications like mobile platforms, featuring two motors mounted on the platform. This design enables an unrestricted steering angle for the wheel without encountering challenges in delivering power and control signals to the motors. The two motors collaborate through two coaxially arranged axes in driving and steering the wheel, ensuring optimal power utilization and minimizing unnecessary mechanical stresses. Continuous cooperation of the two motors in driving and steering the wheel can be achieved using a motion synthesizer. This device accepts two rotational motions from the motors and, depending on the required operation of the wheel mechanism, produces appropriate rotational motions for driving and steering the wheel.

Drive Unit for an Industrial Transport Vehicle
20170101005 · 2017-04-13 ·

A drive unit, in particular for an industrial transport vehicle, is at least comprised of a gearbox with at least one gear stage, a drive motor and a running wheel. To minimize the costs when there are substantially greater loads on the running wheel, there are provisions in accordance with the invention for the running wheel to be directly connected to a bevel gear on the output side, which is supported by a first bearing element for accommodating the load and by a second bearing element that serves to provide stabilization and that is supported in the gearbox . The first bearing element bears all of the loads here, whereas the second bearing element with substantially smaller dimensions merely has to cushion tilting forces that arise.

Steerable wheel side of a drive axle
