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 an at least one flexible clutch member, an at least one brake pad, and an actuator. The at least one flexible clutch member may have an outer diameter arranged about the shaft. The at least one brake pad may be arranged on the outer diameter of the at least one flexible clutch member. The actuator may be arranged to axially displace the at least one flexible clutch member. The at least one flexible clutch member may expand radially outward when axially displaced by the actuator, which may displace the at least one brake pad arranged on the outer diameter of the at least one flexible clutch member radially outward to contact at least one of the plurality of rollers, preventing rotation of the roller.

A wheel/hub assembly includes an axle shaft, a wheel, and a hub supporting the wheel on the axle shaft. The wheel/hub assembly has a target resonant frequency of vibration. A tuned mass-spring damper is vibrationally coupled to the wheel/hub assembly, and has a counteracting resonant frequency of vibration that is predetermined with reference to the target resonant frequency of vibration.

Motorized wheel assembly with quick release

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.

Combined wheel

A combined wheel includes spokes, steel bushings, a rim, a brake pad, pins and a backing ring. The spokes are placed in respective empty slots between adjacent connecting blocks, and clamping grooves therein are matched with the connecting blocks. The pins are installed into holes of the spokes and the connecting blocks. A left end face of a backing ring is matched with the back of the spokes. A plurality of screws connect the backing ring, the connecting blocks and the spokes and are fitted into the steel bushings. The brake pad is fixed to two pluralities of bosses by a second plurality of screws. In use of the combined wheel, both radial force and axial force generated in the running of the wheel can be counteracted on the spokes. The annular brake pad is installed on the inner wall of the rim, thereby increasing the brake radius.

SYSTEM FOR TRANSMITTING CONTROL PRESSURES AND/OR WORKING PRESSURES

A system (40) for transmitting control pressures and/or working pressures from a wheel-hub pressure medium supply (20, 21, 22), in particular from a wheel-hub pressure medium rotary union (21), to a vehicle rim (2) mounted on the wheel hub (1). The system (40) has a receiving part (41), which has a central region (55) with a central opening (44) and at least one extension region (43) projecting radially from the central region (55), at least in some regions. The receiving part (41) can be connected to the wheel hub (1) by means of the at least one radially projecting extension region (43), in a detachable way, and the control pressures and/or working pressures can be transmitted from the wheel-hub pressure medium supply (20, 21, 22) to the opening (44).

FILTER FOR PROTECTING BEARING SYSTEM AND ASSOCIATED DRIVE WHEEL END
20200340534 · 2020-10-29 ·

A drive wheel end includes a hub assembly, an axle, an axle shaft passing through an interior of the axle and rigidly coupled to the hub assembly outside the interior, a bearing system including (i) at least one bearing between the hub assembly and the axle and (ii) a bearing seal between the at least one bearing and an air side of the bearing system, and a filter spanning gap between the axle and at least one of the hub assembly and the axle shaft externally to the axle, to filter flow between the bearing system and the interior. The filter may include a frame and a flexible lip. The frame forms a central aperture and at least one opening radially outwards from the central aperture, and includes a size-discriminating material covering each opening. The flexible lip extends radially inwards from the frame.

NON-PNEUMATIC TIRES WITH BRAKE COOLING SPOKES

A non-pneumatic tire includes a wheel hub portion, a tread ring portion, and a plurality of flexible spokes extending between and coupled to the wheel hub portion and the tread ring portion. A hollow core is positioned between adjacent flexible spokes or formed within each flexible spoke. The plurality of flexible spokes are configured to cyclically move between a narrow position to a wide position when the non-pneumatic tire is attached to a vehicle and is rolling on a road surface such that the plurality of flexible spokes act as a bellows that pumps air from one side of the non-pneumatic tire to another side of the non-pneumatic tire.

Hub for heavy-duty vehicle

A hub for a heavy-duty vehicle and for mounting a wheel for relative rotation comprises a substantially cylindrical body having axially opposite end portions and a longitudinal central axis. Each of a pair of bearing receiving bores is formed in the cylindrical body at a respective axially opposite end portion of the cylindrical body. A circumferential envelope has an outer diameter and is formed on the cylindrical body about one of the pair of bearing receiving bores. A flange extends radially outward from the cylindrical body at a location between the pair of bearing receiving bores. A barrel portion of the cylindrical body extends between the flange and the circumferential envelope and has an outer diameter. The hub provides sufficient strength and minimizes weight by incorporating specific longitudinal profiles and ratios and/or relationships of various dimensions of the barrel portion 104.

Planetary gear device and vehicle wheel drive device

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.
