An elevator guide rail block assembly configured for use with an elevator car or counterweight guide rail is provided. The elevator guide rail block assembly includes a framework and a plurality of cams supported for rotation by the framework and positioned between spaced apart support elements. The spaced apart support elements are connected together by a retention element. An actuator element is configured to actuate rotation of the plurality of rotatable cams. A clamp structure is attached to the framework and is spaced apart from the plurality of rotatable cams. In a rotated orientation, each of the plurality of rotatable cams engage a face of an elevator or counterweight guide rail and the clamp structure engages an opposing face of the elevator or counterweight guide rail to form a clamping action configured to secure the elevator guide rail block assembly to the elevator car or counterweight guide rail.

An assembly for a tire inflation system includes a ring portion. The ring portion has an outer surface and an inner surface. A first projection and a second projection each extend from the inner surface. A valve assembly is connected to the ring portion and disposed in from the outer surface.

Assembly for a tire inflation system

An axle assembly having a constant shaft disposed at least partially through a bearing hub assembly. The constant shaft defines a fluid conduit therethrough. A steering knuckle is disposed at least partially about the constant shaft. The axle assembly may include a bearing spacer disposed about the constant shaft, the bearing spacer being disposed at least partially axially between the bearing hub assembly and the steering knuckle. Additionally, a first rotary seal and a second rotary seal may be disposed radially between the bearing spacer and the constant shaft. The first and second rotary seals may at least partially define a fluid chamber in fluid communication with the constant shaft fluid conduit. Further, a port may be disposed through the bearing spacer, wherein the port is in fluid communication with the fluid chamber.

A first biasing member disposed between the cover portion and the diaphragm in a cover cavity defined thereby. A control cavity defined by the body portion and the diaphragm, and at least one control port defined by the body portion and in fluid communication with the control cavity. A tire port defined by the body portion and in selective fluid communication with the control cavity. A first and second conduit disposed in the body portion in fluid communication with a third and fourth conduit disposed in the cover portion. An equalization valve assembly disposed in one of the conduits to control fluid communication between the cover cavity and the control cavity.

Wheel valve assembly and the tire inflation system made therewith

A tire inflation system for a vehicle having a control unit including an internal fluid conduit. At least one extended stroke valve including a housing in fluid communication with the internal fluid conduit and a wheel assembly. The extended stroke valve includes a hollow outer shaft having a first flange. A first biasing member is disposed about the hollow outer shaft between the first flange and an annular protrusion defined by the housing. The extended stroke valve also includes an inner shaft having a second flange, wherein the inner shaft is at least partially disposed in the hollow outer shaft. A second biasing member is disposed about the inner shaft between the second flange and a surface defined by the hollow outer shaft. In addition, a sealing member is coupled with an end of the inner shaft opposite the second flange.

Extended stroke, high flow, valve and the assembly made therewith

A dynamic weight shift suspension system for shifting the tandem axle loads on a vehicle. The system includes a first airbag connected between the drive axle of a tandem and the vehicle frame, and a second airbag connected between a tag axle of a tandem and the vehicle frame. The system also has a mechatronic control unit comprising at least one port and at least one solenoid. The mechatronic control unit is in direct fluid communication with the airbags and an air supply via fluid communication lines.
