An axle for heavy-duty vehicles, the axle comprising first and second grooves formed about the axle. The first and second grooves include a cross-sectional geometry that forms integrated annular fixturing locations about the axle for selectively mounting a component of a braking system.

Axle for heavy-duty vehicles

A hubcap for a heavy-duty duty vehicle that includes mounting structure that is formed with and cooperates with a side wall of the hubcap to provide a stiff, rigid structure that enables non-cantilevered connection to a wheel hub. The mounting structure can be a plurality of elongated bosses circumferentially spaced about the side wall that are formed with corresponding elongated bolt openings to enable the non-cantilevered attachment to the wheel hub. The elongated bosses cooperate with the hubcap side wall to provide a stiffened or rigid structure between the elongated bolt openings for increased and more uniform clamping force on a sealing gasket between the hubcap and the wheel hub. The hubcap profile provides clearance for removal of an outboard mounted disc brake rotor in heavy-duty vehicle wheel end assemblies that include such rotor configurations. The hubcap may support simple mounting of a hub odometer.

Hubcap for heavy-duty vehicles

An axle assembly includes a central tube and an axle spindle. The axle spindle is fixed to the central tube. The axle spindle has a tubular first section and a tubular second section extending from the first section. The second section has an outer diameter. The second section has a bearing support surface. A tubular transition section is located between the first section and the second section. An annular shoulder portion is formed in an axial end segment of the tubular transition section adjacent the second section. The shoulder portion has at least one annular profile located in the shoulder portion between the annular shoulder surface and the bearing support surface. The annular profile is defined by a surface with a diameter not less than the outer diameter of the second section. An antilock braking system sensor bracket locator nub is integrally formed in the tubular transition section. An antilock braking system sensor bracket engages the antilock braking system sensor bracket locator nub for proper positioning of an antilock braking system sensor.

A wheel hub for a heavy-duty vehicle includes a first and second tubular hub segment. The first tubular hub segment has a first annular end surface. The second tubular hub segment has a second annular end surface and a radially extending flange. A continuous, circumferential joint is formed at the interface of the first annular end surface and second annular end surface.

Wheel hub for heavy-duty vehicles

A disc brake rotor and hub assembly for a heavy-duty vehicle. The disc brake rotor and hub assembly includes a hub portion. The hub portion is receivable on, and rotatable about, an axle spindle of a heavy-duty vehicle. A rotor portion includes a disc segment, a mounting segment and a cylindrical sleeve segment connecting the disc segment to the mounting segment. A flange portion connects with the rotor portion and separately with the hub portion. Optionally, the rotor portion connects directly to the hub portion. A smallest inner dimension of the rotor portion is greater than a largest outer dimension of the hub portion to facilitate removal of the rotor portion without removing the hub portion from the axle spindle.

Hub and rotor assembly

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

Self-steering axle assembly has an axle with central tube having a longitudinal central axis. A king pin is connected with an end portion of the axle. A knuckle is connected with the king pin. The knuckle includes a torque plate section. A first arm of the knuckle extends from a side of the torque plate section and receives a first end portion of the king pin. A second arm extends from the torque plate section in the same direction as the first arm. The second arm receives a second end portion of the king pin. A spindle is friction welded to the torque plate section and has a longitudinal central axis. The torque plate section has at least one surface on the torque plate section extending substantially perpendicular to the longitudinal central axis of the spindle. A tool engages the surface during friction welding of the spindle to the torque plate section. The relative locations of the axle, spindle and king pin enable an air disc brake actuator to avoid contact with components of the heavy-duty vehicle during steering and with the ground and debris.

Self-steering axle knuckle

A wireless sensor for a wheel end assembly of a heavy-duty vehicle is provided. The wheel end assembly includes a wheel hub and a hub cap mounted on the wheel hub. The sensor includes mounting means disposed in the hub cap. Sensing means are mounted on the mounting means to sense at least one condition of the vehicle. A processor is mounted on the mounting means and is electrically connected to the sensing means to process data from the sensing means. Communication means are mounted on the mounting means and are electrically connected to the processor to communicate the processed data to a user. An electrical energy storage device is mounted on the mounting means and is electrically connected to the sensing means, the processor and the communication means, enabling the sensor to be independent from the vehicle power supply. The sensor also accommodates components of a tire inflation system.
