An assembly () for a central tire inflation system includes a housing having a first end and a second end. The housing defines a fluid conduit disposed through the first and second ends. The assembly also includes one or more sensors () having a portion disposed in the fluid conduit. Further, a power source () is in electrical communication with the sensor. The assembly additionally includes a kinetic energy device () in electrical communication with the power source. The kinetic energy device may comprise a magnet () sliding on a guide (). As an alternative, the kinetic energy device may comprise a turbine ().

Integrated-sensor valve apparatus

A method and system for latching a solenoid. The method includes providing an axle disconnect system having an actuator with an electromagnetic coil, a housing, an armature, and a rotatable and axially slidable slide ring. The electromagnetic coil may then energized creating a magnetic flux through a magnetic circuit thereby causing the armature to move from a first to a second axial position where the magnetic flux through the magnetic circuit is uninterrupted. Once the electromagnetic coil has been energized, it is de-energized thereby allowing an amount of residual magnetism within the housing and/or the armature to maintain the armature in the second axial position. The armature is maintained in the second axial position by the magnetic flux of the magnetic circuit being uninterrupted.

Method and system for latching an actuator

An axle disconnect system including an actuator having an energizable coil in an overmold that is at least partially surrounded by a coil housing. An armature is in sliding engagement with the housing such that the magnetic flux through the magnetic circuit is uninterrupted. Disposed between one of (i) the housing or armature and (ii) a sliding collar is a slide ring. The sliding collar is located directly radially inward from the slide ring. A first end portion of the sliding collar has a set of axially extending teeth. Radially inward from the first end portion of the sliding collar is a return spring groove having a return spring. An outer surface of a second end portion of an output gear has a set of axially extending teeth that are selectively engageable with the teeth on the first end portion of the sliding collar.

A tire condition telematics system. The system includes a vehicle having an onboard computer and one or more wheel assemblies with one or more tires with a tire tread. A prediction as to when said tire tread will fall below a minimum tread depth in performed. The prediction is based on an amount of distance said wheel assemblies experience said wheel slip condition, a distance said wheel assemblies drive over said one or more road materials, a distance said wheel assemblies drive in rain and snow, a distance one or more loads are on said vehicle.

Tire condition telematics system

A method of providing road and vehicle diagnostics, includes providing a vehicle axle system having a first axle half shaft housing, a second axle half shaft housing and a differential housing. Attached to one or more of the housings is one or more tri-axis accelerometers. In communication with the accelerometers is one or more data processors configured to receive and analyze data from the accelerometers. An occurrence of one or more road events is determined by one or more spikes in the Z-direction of the data collected from the accelerometers. A depth of the road event is determined by a magnitude of the positive and negative changes in acceleration of the spike in the Z-direction and a length of road event is determined by an amount of time between two spikes of opposite magnitudes in said Z-direction. Once identified, the time and geographic location of the road event is identified.

Method and apparatus for providing road and vehicle condition diagnostics

A method for shifting tandem axle loads on a vehicle including an air suspension circuit having a three way valve, a first air spring connected between a drive axle of a tandem and a vehicle frame and a second air spring connected between a tag axle of the tandem and the vehicle frame. A diameter of the first air spring is larger than a diameter of the second air spring. The system also has an air supply, a first fluid line connected between a port one of the three way valve and the first air spring and a second fluid line connected between a port three of the three way valve and the second air spring.
