Abstract: A tire inflation system having a spindle that is configured to support a wheel bearing. A passage for routing pressurized gas may be provided with the spindle or with a sleeve that may be disposed on the spindle.

Abstract: A tire inflation system for a vehicle. The tire inflation system may include a gas supply subsystem that may supply pressurized gas to a tire via first conduit that may be connected to an axle shaft.

Abstract: A tire inflation system having a peristaltic pump. The peristaltic pump may output a pressurized gas when a flexible tube of the peristaltic pump rotates with a wheel end assembly about an axis.

Abstract: A tire inflation system having a first conduit and a flange. The first conduit may supply a pressurized gas for inflating a tire. The flange may be coupled to an axle flange. The flange may have a passage that routes the pressurized gas through the flange.

Abstract: A planetary gear set module having planetary gear set and a biasing member. The biasing member may exert a biasing force on a component of the planetary gear set and may permit the component to rotate when sufficient torque is provided to overcome the biasing force.

Abstract: An axle assembly having an electric motor module. The electric motor module may be coupled to a differential assembly. A rotor of the electric motor module may be coupled to a pinion of the differential assembly with a first coupling.

Abstract: A method of controlling a brake system for a vehicle. A foundation brake may be applied to provide a foundation brake torque. Vehicle speed data, vehicle inclination data, and foundation brake pressure data may be obtained. A foundation brake torque profile may be determined that includes a set of vehicle speed values, a set of foundation brake pressure values, and a set of foundation brake torque values.

Abstract: A flexible coupling assembly that may be provided with a vehicle drivetrain. The flexible coupling assembly may include a spacer ring, a first flexplate assembly, and a second flexplate assembly. The first and second flexplate assemblies may be spaced apart and fixedly disposed on the spacer ring. The first and second flexplate assemblies may be configured to independently flex.

Abstract: A self-energized disk brake assembly includes gain stabilization features for controlling the multiplication of applied force against a rotatable brake member. The brake assembly includes a first brake pad supported about a first pivot and a second brake pad supported about a second pivot. An actuator applies a force to drive the brake pads into the rotatable brake member. Frictional force between the brake pads and the rotatable brake member pulls the brake pads into further engagement generating an increase in braking force from self-energization. A position of the first and second pivots is adjustable to control the amount of braking force generated from self-energization.

Abstract: An air spring for a vehicle suspension includes a resilient spring body that is surrounded by a protective cover. The protective cover protects the resilient spring body from rupturing when used in harsh vehicle conditions. Preferably, the protective cover is comprised of a rigid or flexible armor material that is resistive to munitions, such as projectiles and razor wire, for example.

Abstract: An independent suspension includes a knuckle connected to a spindle, and an upper control arm that is connected to the knuckle with a first joint assembly. A lower control arm is connected to the knuckle with a second joint assembly. The lower control arm includes a base portion, a pair of laterally extending mounting arms, and a bracket portion that extends in a vertical direction. The bracket portion includes at least two upwardly extending bracket arms that define an opening for receiving a wheel drive shaft. The wheel drive shaft defines an axis of rotation, and the bracket portion supports an air spring plate at a position directly above the axis of rotation.

Abstract: A brake assembly includes a brake pad movable on a support. The support is pivotally mounted to provide adjustment of an angle defined between the support and a centerline of a rotor. A force applied to the brake pad causes engagement between the rotor and the brake pad. A frictional force drives the brake pad along the support to increase the magnitude of braking force beyond the force applied by the actuator. The increase in braking force is proportionally controlled by adjusting the angle.

Abstract: A brake assembly has a caliper with a first brake pad and a second brake pad. The first brake pad is moveable relative to the caliper. A brake actuator moves the first brake pad and has a first threaded member and a second threaded member. The first threaded member has first thread characteristics for moving the brake actuator at a first speed and a first force. The second threaded member has a second thread characteristics for moving the brake actuator at a second speed and a second force. The first speed is greater than the second speed while the first force is lower than the second force.
