Abstract:
A heavy goods vehicle has several wheel pairs forming a driven wheel axle, which wheel pairs are each supported by a separate rocker arm, which extends between the wheels of the respective wheel pairs and carries on opposite sides two wheel hubs on which the wheels can be attached. For each wheel of the wheel pair there is provided an independent wheel drive which consists of an electric motor and a reduction stage, which transfers the drive motion of the electric motor to the respective wheel hub. For each wheel of the wheel pair there is provided an independent wheel brake, which is arranged on an outside of the respective electric motor and/or the respective reduction stage facing away from the respective rocker arm and which is arranged, together with the respective electric motor and the respective reduction stage, inside the respective wheel hub and the associated wheel axle.
Abstract:
A wheelchair has a base and a plurality of wheels supporting the base on a supporting surface. At least one of the wheels is a driven wheel. One of the wheels may be a non-driven wheel. One or more of the wheels, driven or non-driven, is adapted to be steered. In a preferred embodiment of the invention, all of the wheels are driven and steered independently of one another. The wheelchair also has a seat that is mounted for movement relative to the base. Movement of the seat is preferably controlled independently of the steering direction of the wheels. The wheelchair may further include one or more sensors for controlling the stability of the wheelchair. These sensors may include wheel position sensors, speed sensors, rate-of-turn sensors, accelerometers, and proximity detectors. Such sensors would be useful in controlling the tracking of the wheelchair, avoiding the occurrence of tipping and tilting, and avoiding impact with obstacles.
Abstract:
Long range hydrogen fueled vehicle which carries at least two passangers, which has at least three wheels, said passengers sitting in tandem and most of the batteries or fuel cell systems are located on the sides of the passengers. The vehicle has an aerodynamically shaped body with substantially reduced frontal area and drag. The body is lightweight, made from shock absorbing materials and structures, and has pressure-airless tires, which enhances the safety of the passengers. The vehicle also includes an advanced hydrogen-electric or hydrogen-pneumatic hybrid propulsion system with quick refueling from existing infrastructure and various additional optional features and systems.
Abstract:
An electric drive for an electric or hybrid vehicle has an electric motor, with which a vehicle wheel is drivable, for instance via an articulated shaft. The the electric drive is embodied additionally with a mechanically actuatable wheel brake, which is actuatable by the electric motor selectively for driving the vehicle wheel via a shiftable distributor gear. The invention has the advantage that the electric motor provided for driving the vehicle wheel is simultaneously used for actuating the wheel brake (24) as well.
Abstract:
A vehicle with zero turning radius employing a minimum of two generally parallel matching annular wheels mounted with independent pneumatic toroidal suspensions fixed coaxially on a chassis. The wheels have mounted on their inner hub sides frictional linings along which run a respectively equal number of circumferentially distributed truncated-bicone-shaped rotors of brush-less dc motors with stator shafts fixed on to the axles of the wheels. Addition of a number of large holonomic wheels in tandem on either side of the two generally parallel wheels makes the vehicle longer and more stable. The large holonomic wheels have tires formed by a toroidal unanimity of disc-like rollers with magnetic or electromagnetic elements radially distributed evenly to make each disc-like roller rotate or resist rotation perpendicular to the holonomic wheel axis by acting as a rotor to motor stator windings attached to the chassis in proximity with the ground-engaging portion of the tire.
Abstract:
A single-wheel driving mechanism for floor transport vehicles is comprised of a gearing housing with at least one gear stage, a flanged-on drive motor, and a driven running wheel. For obtaining the smallest possible installation space or achieving a simplified installation or removal of the single-wheel driving mechanism, in conjunction with high transmission of force at the same time, the running wheel is directly connected with torsional strength with a gear of the transmission, and the gear of the transmission is rotatably supported on a support element.
Abstract:
A power-dividing device for a working vehicle includes a case member, an input shaft supported by the case member so that a first end portion of the input shaft can be operatively connected to a driving source, a PTO unit having a PTO shaft supported by the case member so as to be offset with respect to the input shaft, a power transmission mechanism accommodated in the case member to transmit power from the input shaft to the PTO shaft, and a first pump unit having a first pump shaft operatively connected to the input shaft and being fluid-connected to an actuator disposed outside.
Abstract:
Front wheels (3) are attached to transmission devices (30) which are mounted to the vehicle body (2) to be rotatable around vertical axes (27), and rotating means (55) are provided between the side of the vehicle body (2) and the transmission devices (30), whereby the front wheels are steered to turn laterally at substantially right angles. An electric motor (40) is attached to the transmission device (30) to be located under the vertical axis (27). A case body (41) of the electric motor (40) is constructed by an outer case part (41A) and a non-loaded side bracket (41B), and a loaded side end portion of the outer case-part (41A) is connected to the transmission device case body (31). The drive shaft (44) is rotatably supported by the non-loaded side bracket (41B) at one end and by the transmission device case body (31) at the other end. A driving portion (34) provided at the other end side of the drive shaft (44) is operatively connected to an axle (28). As a result, a traveling drive device section can be constructed to be compact with assembling easiness.

The invention relates to an electric drive (10), in particular for an electric or hybrid vehicle. The electric drive (10) has an electric motor (14), with which a vehicle wheel (12) is drivable, for instance via an articulated shaft (20). The invention proposes that the electric drive (10) be embodied additionally with a mechanically actuatable wheel brake (24), which is actuatable by the electric motor (14) selectively for driving the vehicle wheel (12) via a shiftable distributor gear (16). The invention has the advantage that the electric motor (14) provided for driving the vehicle wheel (12) is simultaneously used for actuating the wheel brake (24) as well. (FIG. 1)
Abstract:
A compact final drive assembly comprises a stationary housing and a rotatable housing. A bent axis hydraulic motor is coupled to the stationary housing. The bent axis hydraulic motor drives a planetary drive unit for driving the rotatable housing. A clutch/brake unit controls the planetary drive unit by braking the planet carrier. The clutch/brake unit is provided with a ring piston that is supplied pressurized hydraulic fluid from the motor inlet port of the bent axis hydraulic motor.
