  • Patent number: 11949294
    Abstract: An assembly comprises a resistor plate for a rotating rectifier assembly (RRA). A shaft bore is defined through the resistor plate for passage of a shaft of an electrical machine, and the resistor plate defines a main annular body around the shaft bore. A first protrusion extends radially outward from the main annular body, so that a first pin bore extends through the first protrusion. At least one contact band is seated in a the pin bore of the resistor plate for mounting a direct current (DC) pin to the resistor plate.

  • Publication number: 20150115702
    Abstract: A foot brake valve for operating a vehicle brake system associated with wheels of the associated vehicle includes a plunger, a primary piston, and a volute spring. The plunger is positioned based on a position of an associated brake pedal depressed by an operator for engaging an associated service brakes of the vehicle. The primary piston positioned based on a position of the plunger. The volute spring biases the primary piston against a depression of the brake pedal.

  • Patent number: 8550426
    Abstract: A dual-motion collar device is described, which elicits an additional motion from an operator when initiating a parking brake release in a vehicle. The collar device comprises top and bottom collars with a compressed and torsionally stressed spring there between, such that the collar device maintains a park brake plunger knob in a locked state. An operator twists the top collar to align interlocking features on the top and bottom collars, and then pushes downward to unlock the collar device. The operator then pushes downward on a park brake plunger knob around which the collar device is installed to actuate a parking brake valve assembly and release the parking brake.

  • Patent number: 8539825
    Abstract: Various embodiments of an adjustable simulator apparatus for testing vehicle components are disclosed herein. The apparatus can be used to test linearly translatable components, such as transmission or brake components, without connecting them to every cooperating component as they would be in a vehicle. In one embodiment, an adjustable simulator apparatus includes a housing having a bore along a generally longitudinal axis and a first retainer and a second retainer disposed in the housing and spaced apart from one another. At least one of the first and the second retainer is adjustable in its position and a compressible member is disposed between the retainers. The apparatus further includes a piston translatable within the bore and a mechanical stop disposed at least partially within the bore of the housing and extends through the second end of the compressible member.

  • Patent number: 8499663
    Abstract: A braking assembly includes a depressible brake pedal. The brake pedal remains in a neutral position when not depressed. A link arm is mechanically linked with the brake pedal. The link arm moves as a function of a position of the brake pedal. A bell crank is mechanically linked with the link arm. The bell crank moves as a function of a position of the link arm. A stop member moves with the bell crank. The stop member abuts against the link arm to prevent the brake pedal from over-travelling beyond a predetermined distance past the neutral position after the depressed brake pedal is released.

  • Patent number: 7247805
    Abstract: A mechanism is provided for actuating a switch that transmits motion from a first component, which moves along a first path, to a system that is attached to the mechanism. The mechanism includes a second component that moves transverse to the first path and a third component having a switch actuating portion, wherein movement of the first component causes the third component to actuate the switch using motion that is generally along the first path.
