A motorized vehicle assembly includes an axle comprising a channel extending along a central axis of the axle, a socket positioned within the channel of the axle, and a motorized wheel configured to be mounted on an end the axle. The motorized wheel includes a boss configured to engage the end of the axle when the motorized wheel is mounted on the axle, an electric motor, a tire mounted on the rotor, and a plug positioned within the boss, the plug configured to engage with the socket when the motorized wheel is mounted on the axle. The electric motor includes a stator fixed to the boss and a rotor surrounding the stator, the rotor configured to rotate relative to the stator. The electric motor is configured to cause the rotor to rotate relative to the stator to cause the tire to rotate.

A first labyrinth seal includes: a drive shaft side annular protrusion that is formed on one of the slinger and the drive shaft seal plate and that protrudes over the circumference of the drive shaft; and a drive shaft side annular groove that is formed on the other of the slinger and the drive shaft seal plate and that recedes over the circumference of the shaft. A second labyrinth seal includes: a carrier-side annular protrusion that is formed on one of the carrier seal plate and the planetary carrier and that protrudes over the circumference of the shaft of the planetary carrier; and a carrier-side annular groove that is formed on the other of the carrier seal plate and the planetary carrier and that recedes over the circumference of the shaft.

An axle assembly includes a first axle shaft. The first axle shaft includes a first conduit. A second axle shaft includes a second conduit. The first conduit and the second conduit are in fluid communication through a chamber. A differential is operatively connected to the first axle shaft and the second axle shaft. The chamber is at least partially disposed within the differential.

The present invention provides a rolling bearing unit for supporting wheel that is able to suppress increase in the dimension in the axial direction due to the installation of a generator and a wireless communication apparatus to a minimum, supply sufficient electric power to a sensor attached to a wheel, and wirelessly transmit output signals of the sensor to an electronic apparatus on the vehicle body. The hub 17 comprises an inner recessed portion 29 on the inner diameter side of the inside portion in the axial direction which has a cylindrical fitting surface section 30 on the inner peripheral surface and is coaxial with the center axis of the hub 17, and a supporting member 67 is supported by and fastened to the inside of the inner recessed portion in a state where the hollow cylindrical supporting member 67 fits the cylindrical guide surface section 70 that is provided in the outer peripheral surface to the fitting surface section 30. A rotor 6 which is an armature is fixed to the inside portion in the axial direction of the supporting member 67 to be coaxial with the supporting member 67, and the wireless communication apparatus 12 is placed inside in the radial direction of the supporting member 67. A through-hole 34 where a wiring 57 is placed opens in the bottom surface 31 of the inner recessed portion 29.

A powered skateboard having a powered wheel. The powered wheel formed of a motor within tire of the wheel. The powered wheel fixed to a truck of the powered skateboard. The powered skateboard including at least one onboard battery to provide electrical power to the powered wheel.

Acoustic medium of ultrasonic grip system consists of piezoelectric generator (1), wheel knuckle (9), ball bearing (10), wheel hub (11), wheel rim (15) and tyre of motor-car (20). The piezoelectric generator (1) creates ultrasound vibrations which are transferred through the acoustic medium to the surface of tyre (17). The ultrasound vibration on the surface of tyre (17) results in the separation of the surface of tyre (17) from the liquid (18) that may be found on tarmac (19) during the rain, which results in the fact that despite the unfavourable weather conditions the motor-car has an optimum rolling surface of tarmac. Also, the vibrations on the surface of tyre (17) in interaction with micro texture of tarmac increases the contact surface of tyre with tarmac, which results in the increase of coefficient of friction, higher grip of tyre and reduction of braking distance of motor-car. The ultrasonic grip system is activated at sudden braking, resp. activation of ABS system. Also, the system is activated on the occasion of activating the ESP and ASR system.

An assembly for a tire inflation system including a spindle having a fluid conduit. The spindle is coupled with a rotary joint spindle, and the rotary joint spindle includes a fluid conduit in fluid communication with the spindle fluid conduit. A fluid collector ring is located about the rotary joint spindle such that the fluid collector ring may rotate. The fluid collector ring is also in fluid communication with the rotary joint spindle fluid conduit.

A wheel end assembly includes a spindle having a passage formed therein. The wheel end assembly also includes a hub cap assembly. The hub cap assembly has an inner housing and an outer housing. The inner housing and outer housing are in fluid communication via an air passage. An air spindle has an inboard portion and an outboard portion. The inboard portion is disposed in the spindle and the outboard portion is disposed in the inner housing. Also, the air spindle has a fluid passage. The fluid passage is in fluid communication with the passage formed in the spindle and the air passage formed in the hub cap assembly. A rotary air seal is disposed around the air spindle. A rotary oil seal is disposed around the air spindle and is spaced apart from the rotary air seal.

A method for attaching a clamping assembly to the frame of a machine includes attaching a sensor assembly to the spindle of a machine such that a wire harness extends through the internal cavity of the spindle and out from the spindle, fishing the wire harness through a breather line, and attaching the wiring harness to the chassis of a machine.

An omni-wheel may include a shaft, a plurality of rollers, and a braking device. The plurality of rollers may be circumferentially arranged about the shaft and arranged radially outward from the shaft. The braking device may include a fluid-filled bladder and a plurality of braking pads. The fluid-filled bladder may be circumferentially arranged about the shaft. The plurality of braking pads may be arranged between the fluid-filled bladder and the plurality of rollers. The fluid-filled bladder may expand radially outward when pressurized, displacing the plurality of braking pads radially outward to contact the plurality of rollers, preventing rotation of the rollers.
