Abstract: A wheel unit for an electric vehicle with a disengageable drive includes a wheel support, a wheel hub rotatably supported by the wheel support, and a wheel pin carried by a member driven by the electric motor and rotatably mounted within the wheel hub, by means of two rolling bearings. A coupling device connects in a releasable way the driven member to the wheel hub. The two rolling bearings that support in rotation the wheel pin have respective outer rings mounted by interference fit within a cylindrical wall of a central opening of the wheel hub, and respective inner rings rigidly connected together by means of a spacer sleeve having a predetermined length. The wheel-hub unit with the two rolling bearings and the spacer sleeve can be assembled before being mounted on the wheel pin.

Abstract: A shifting device including at least one coupling device, a shaft, a sliding sleeve-of the coupling device which is arranged in an axially moveable and rotationally fixed manner on the shaft and an actuator arrangement of the coupling device for axially moving the sliding sleeve. At least one coupling toothing is associated with the coupling element which can rotate about a rotational axis with respect to the shaft and a counter toothing corresponding to the coupling toothing is associated with the sliding sleeve in a rotationally fixed manner. At least one annular actuator element of the actuator arrangement surrounds the periphery of the sliding sleeve about the rotational axis.

Abstract: An integrated wheel disconnect system is provided, including a mechanically actuated engagement interlock selector assembly. The engagement interlock selector assembly including a housing, an interlock mechanism disposed in the housing, a spring disposed in the housing, and an actuator assembly, arranged to displace the interlock mechanism towards or away from the spring. The engagement interlock selector assembly is operated by an actuator module, such as a pin, sliding along an external ramp on the interlock mechanism, the mechanism moving axially to selectively engage and disengage the wheel hub from the drive axle.

Abstract: In a method for influencing the traction force during shifting operations of a manual transmission in vehicles having at least two drive axles, the drive system of the first axle is activated in such a way that the interruptions in traction force occurring at the second axle during shifting operations of the manual transmission are at least partially compensated for.

Abstract: Drive assemblies and related methods are provided particularly suited for a snowblower. The drive assemblies include a transmission wheel disposed about a shaft and rotatably movable for rotating at least one wheel. The transmission wheel has a contact surface. The drive assemblies also include a drive pulley having a drive surface. The drive pulley is rotatable and configured for causing the transmission wheel to rotate when the drive surface and the contact surface of the transmission wheel are in contact. At least one brake clutch is disposed about an end of the shaft to provide independent control to the at least one wheel.

Abstract: An electric hub having a clutch means is used in wheels of an electric wheelchair and includes a hub means, a clutch means and an elastic body. The hub means includes an outer hub and an inner hub provided in its interior. The end face on one side of the outer hub is provided with a first gear. A projecting shaft extends from one side of the inner hub to correspond to the first gear. One side of the hub means is connected to the clutch means. The clutch means includes a rotary assembly and a movable disk connected to the projecting shaft. The movable disk is movable relative to the axial direction of the projecting shaft. A mating second gear is provided to correspond to the first gear. The elastic body is provided between the inner hub and the movable disk to control the clutching operation between the outer hub and the movable disk.

Abstract: A clutch assembly selectively transfers rotational energy from a rotatable drive shaft to a wheel. The clutch assembly includes a drive transmitting member rotationally coupled to the drive shaft, a clutch member rotationally coupled to the drive transmitting member and movable relative to the drive transmitting member, and a wheel drive member adapted to receive a rotational energy from the clutch member. In one aspect, the clutch assembly is for selectively transmitting drive force from a rotational drive source to a single wheel of a multi-wheeled power driven device. The clutch assembly includes a member axially movable relative to the rotational drive source to transmit rotational energy toward the wheel when the member is in one axial position.

Abstract: A drive coupling mechanism for use in connecting an axle or other drive shaft to a wheel hub for use in a snow thrower or other vehicle, or in other applications where a driven wheel is engaged to a drive shaft. A slider member is mounted on and driven by the axle, and cooperating engagement structures located on the slider and the inner surface of the wheel hub are used to engage and disengage the wheel hub from the axle depending on the location of the slider member. A bearing ring or similar structure may be used to facilitate the engagement of the cooperating engagement structures.

Abstract: A wheel drive disconnect system for use in electrically powered vehicles for transporting the physically challenged having at least one wheel comprising a rim, a wheel hub sleeve, and a radially extending plate connecting the rim and hub sleeve. A rotatably driven shaft drive is freely received by the hub sleeve and a releasable drive transmitter axially freely receives the drive shaft device and has a first position in which it is driven and a second axially displaced position in which it is not. Protrusions and drive surfaces provided between the wheel plate and drive transmitter are in radial alignment for driving the wheel in rotation when the drive transmitter member is in the first position and for permitting free wheeling of the wheel when the drive transmitter has been axially displaced and the protrusions and drive surfaces are out of radial alignment.

Abstract: A four wheel drive working vehicle such as a front mower has a dual one-way clutch mechanism interlocked to right and left dirigible wheels. When the vehicle makes a turn in forward or backward running, the clutch mechanism breaks drive transmission only to an outer one of the dirigible wheels.

Abstract: An inboard hub lock assembly integrated into a steering knuckle. Teeth are provided on an end of the CV housing and an adjacent flange extending from the wheel hub. A clutch member with corresponding teeth is movable between 1) an outboard position engaging the CV housing teeth and the wheel hub flange teeth, thereby transmitting drive power from a stub shaft to the wheel hub, and 2) an inboard position engaging only the CV housing teeth, thereby permitting the wheel hub to rotate freely relative to the stub shaft. A spring biases the clutch member to a 4×2 mode fail safe position by biasing the clutch member to the inboard non-engaging position.

Abstract: An integrated wheel end assembly for a vehicle including a wheel hub, a stub shaft, a torque flange and a bi-directional overrunning clutch member is configured such that the clutch automatically acts as a hub lock. The wheel hub is drivingly engaged to a drive flange mounted at an inboard end thereof. An outer circumference of the drive flange has a plurality of external teeth spaced evenly therearound. An outboard end of the stub shaft is rotatingly supported in the wheel hub and an inboard end thereof defines a housing for a CV joint. This CV housing and the drive flange are positioned axially adjacent to each other. The bi-directional overrunning clutch member comprises two clutch plates, one drivingly connected to the CV housing and the other drivingly connected to the drive flange. In a first configuration the clutch plates are disengaged such that the rotating CV housing causes only the corresponding clutch plate to rotate and no drive torque is transferred from the half shaft to the wheel hub.
