A system may include a planetary gear system having a sun gear, a ring gear, and a plurality of planet gears mounted on a rotatable carrier. Also, the system may include a first motor and a second motor aligned coaxially along a shared central axis. Furthermore, the system may include a shared input gear coupled to the planetary gear system, where the planetary gear system is configured to combine torque contributions from the first motor and the second motor and transmit the combined torque to an output shaft. In addition, the system may include a synchronization mechanism configured to maintain alignment of rotational speeds between the first motor and the second motor.

A mounting clip for securing a component to a protrusion, comprising: an adjustable loop configured to grip said protrusion, the adjustable loop defining an internal perimeter within which said protrusion is received; and a pair of legs extending from the adjustable loop and configured to exert a biasing force upon a component positioned therebetween, each leg comprising a first end connected to the adjustable loop and a second distal end; wherein the legs are resiliently biased towards a nominal position with respect to one another, and wherein each leg crosses the other at a point between said first and second ends such that, upon compression of the legs towards one another, the internal perimeter of the loop is expanded; and, upon release of the legs, the legs return towards the nominal position such that the internal perimeter of the loop is contracted.

An axle assembly (5) comprises a sensor (18) and provision of an electrical ground connection from a sensor to a vehicle ground potential in order to provide data about an axle (10) and/or a wheel hub connected to the axle. In particular, an inner surface (14) of an internal cavity (16) of an axle (10) is used as an electrical grounding point for a sensor (18), thereby protecting the ground connection and sensor from harsh environments. In an embodiment, an axle assembly (5) comprises a support member (12) adapted to be disposed within the interior cavity (16) of the axle (10), and the sensor (18) is operatively connected to said support member (12). The sensor (18) comprises an electrical ground input (20) electrically connected to a surface (14) of the axle (10) within the cavity (16). Such an axle assembly (5) may be provided as a constituent component in a vehicle.

A disc brake assembly for a heavy commercial vehicle, the disc brake assembly comprising first and second brake pads for contacting a rotor during a braking operation; a brake carrier for receiving at least the first brake pad; a brake housing arranged to slide with respect to the brake carrier; and a removable insert located between the first and second brake pads and configured to separate the first and second brake pads from one another prior to installation of the disc brake assembly on a vehicle; wherein at least one portion of the insert extends to an exterior of the brake housing.

A dual axle steering system for a vehicle, the steering system comprising a first axle and a second axle, wherein both the first axle and the second axle are steerable; a first linkage for transmitting steering motion to wheels supported on the first and second axles at a first side of said vehicle; and a second linkage for transmitting steering motion to wheels supported on the first and second axles at a second side of said vehicle. Each linkage comprises a fore tie rod for transmitting steering motion to a fore wheel supported on the first axle, an aft tie rod for transmitting steering motion to an aft wheel supported on the second axle, and a connection arrangement between the fore and aft tie rods for transmitting steering motion to the fore and aft tie rods. At least one connection arrangement is articulated.

A brake system and a method of control. The brake system comprises a friction brake, a sensor unit, and a controller. The sensor unit is disposed on a brake pad assembly of the friction brake and comprises a first sensor and a second sensor that is electrically connected to the first sensor.

A tang on a spindle nut washer of a wheel end assembly facilitates retention and alignment of bearing and seal components within a wheel hub during installation and removal of the hub onto and/or from a wheel spindle. In one embodiment, the tang protrudes from an outer circumferential portion of the washer to interact with a circumferential slot in the wheel hub. The washer is installed within the hub at an offset orientation to position the tang within the slot, which assures axial retention of the washer within the hub. The washer can then engage an outboard wheel bearing cone to facilitate wheel hub installation on the spindle, and can also facilitate subsequent hub removal from the spindle. Upon completion of wheel end assembly, the washer thickness can also provide confirmation that wheel bearings and seal components are fully seated to recommended bearing preload and/or wheel end play limits.

A method of lubricating a transmission system including: scavenging, via a lubrication tube of a lubrication system disposed within the transmission system, oil from at least one of a plurality of gears; directing the scavenged oil from the lubrication tube to a plurality of oil conduits extending from the lubrication tube; and translating a shift assembly in a longitudinal direction such that the shift assembly actuates a plurality of poppet valve assemblies disposed in the plurality of oil conduits between a closed position and an open position. The scavenged oil circumventing the plurality of poppet valve assemblies in the open position and the plurality of poppet valve assemblies form a seal with the plurality of oil conduits in the closed position.

A brake system and method of control. A brake pad assembly is actuatable from a retracted position to an extended position with a fluid. The method includes determining whether a running clearance is acceptable based on a first fluid supply pressure associated with the brake pad assembly being in a retracted position and a second fluid supply pressure associated with the brake pad assembly being in an extended position.

An axle assembly comprising a support structure, a mounting plate, an electric motor module, a transmission module, and a wheel end assembly. The electric motor module extends from a first side of the mounting plate. The transmission module extends from the second side of the mounting plate. The wheel end assembly extends from the transmission module.
