Abstract:
A safety device for a truck, tractor, or trailer wheel assembly is an integral member with mounting holes for receiving axle studs of the wheel assembly to fix the integral member to the axle. The integral member has a radially extending portion which, when the integral member is fixed to the axle, overlaps the wheel studs of the wheel assembly but is free of any connection to the wheel studs. The integral member has tapered holes radially outbound of its mounting holes. In another embodiment, the integral member of the safety device has a cylindrical, interiorly threaded, sleeve portion and a radial portion extending radially outwardly from the sleeve portion with the radial portion having tapered holes radially outbound of the sleeve portion.
Abstract:
A hub arrangement for twin wheels comprises a stationary carrier; an intermediate hub which is rotatable about an axis of rotation and which can be driven by a drive shaft; a differential gear having an input which is connected to the intermediate hub; a first wheel hub which is connected to a first output of the differential gear; and a second wheel hub which is connected to a second output of the differential gear. The hub arrangement furthermore comprises a first braking apparatus which is effective between the stationary carrier and the intermediate hub and a second braking apparatus which is effective between the stationary carrier and the second wheel hub or between the intermediate hub and the second wheel hub. In this respect, the first braking apparatus and the second braking apparatus can be actuated separately from one another.
Abstract:
A multi-functional active container (e.g., luggage or suitcase) with a plurality of sensors and actuators is described. The container may include a body defining an enclosure and having at least one opening. The container may include a processor, a wireless receiver, and an electronically controllable lock. The processor can selectively lock or unlock the electronically controllable lock based on signals received via a wireless receiver (e.g., via Wi-Fi or BLUETOOTH connections). In some examples, a distance between the active container and a remote device (e.g., a smart phone) can be determined (e.g., based on relative GPS signals or connection strength) and if the distance exceeds a threshold, the electronically controllable lock can be activated to secure the container. Further, the container may include a rechargeable power source for powering external devices and an integrated weight sensor for detecting the weight of the container.
Abstract:
A fuel-saving apparatus using a variable preload of vehicle bearings according to the present invention includes a housing that supports a driving shaft of a vehicle, a bearing that is mounted in the housing and rotatably supports the driving shaft, and a variable preload unit that is provided at the housing or a side adjacent to the housing and applies a preload to an outer wheel or an inner wheel of the bearing. The fuel-saving apparatus using such a variable preload may reduce a driving load acting on the driving shaft by a fixed preload acting by the bearing, thereby reducing the driving load of an engine and saving fuel.
Abstract:
The presently claimed invention relates to a road wheel comprising a mounting disc, a dish-shaped transitional wall having an outer edge, a rim with an annular cylindrical wall attached along a first rim edge to the outer edge of the transitional wall, and a stiffening flange attached to the rim along a second rim edge opposite the first rim edge wherein the flange provides radial support to the second rim edge of the cylindrical wall to resist deflection.
Abstract:
A dual wheel axle assembly includes an axle, a hub coupled to the axle, a rotor coupled to the hub, a surface of the axle assembly inboard of the hub, and an adapter. The adapter is coupled to the rotor or the hub. The adapter has an encoder ring portion positioned at a first distance from the surface of the axle assembly, wherein the first distance is substantially equal to a second distance from a corresponding surface of a single wheel axle assembly to an encoder ring portion of the single wheel axle assembly without the adapter.
Abstract:
A torque transmission and sealing assembly includes a ring gear having a first axial end, a second axial end opposite the first axial end, an inner surface including a plurality of teeth and an axial-facing surface at the first axial end, a barrel portion joined to the second axial end of the ring gear, and a plurality of annular, axial extending fingers integrally formed with the ring gear and extending from the axial-facing surface.
Abstract:
A wheel assembly, for use on an off-highway vehicle, includes a generally cylindrical wheel hub extending axially from a first end to a second end around an inner volume. A hub adapter is secured to the second end of the wheel hub, the hub adapter including a peripheral shoulder, which has a first shoulder surface axially facing in a direction extending from the second end towards the first end. A first wheel rim is mounted to the peripheral shoulder of the hub adapter at the first shoulder surface.
Abstract:
A centering system for centering the inner and outer wheels of a dual wheel assembly on a hub includes at least three centering sets. Each centering set has an inner sleeve and a separate outer sleeve. Each inner sleeve fits between a wheel stud on the hub and a bolt hole in the inner wheel to center the inner wheel. Each outer sleeve fits between the wheel stud and a bolt hole in the outer wheel to center the outer wheel. The inner sleeves can also include a section that fits between the wheel stud on the hub and a bolt hole in the brake drum to center the brake drum.
Abstract:
A casing has an inner end, an outer end, and an internal drive mechanism. The internal drive mechanism has an outer wheel mounting hub at the outer end of the casing and an inner wheel mounting hub at the inner end of the casing, both supported for rotation about an axis. A motor operates the internal drive mechanism to impart rotation to the wheel mounting hubs with equal force whilst allowing the wheel mounting hubs to rotate at different speeds. The internal drive mechanism further has a carrier that is disposed between the inner wheel mounting hub and the outer wheel mounting hub and that is rotated about the axis by the motor. The carrier contains a differential gear mechanism having an outer output shaft for imparting rotation to the outer wheel mounting hub and an inner output shaft for imparting rotation to the inner wheel mounting hub.
