Patent number: 11949294Abstract: 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.Type: GrantFiled: March 13, 2021Date of Patent: April 2, 2024Assignee: Hamilton Sundstrand CorporationInventors: Kyle S.

Patent number: 8550426Abstract: 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.Type: GrantFiled: January 19, 2011Date of Patent: October 8, 2013Assignee: Bendix Commercial Vehicle Systems LLCInventors: Duane R.

Patent number: 8539825Abstract: 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.Type: GrantFiled: June 22, 2011Date of Patent: September 24, 2013Assignee: Bendix Commercial Vehicle Systems LLCInventors: Timothy J.

Patent number: 8499663Abstract: 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.Type: GrantFiled: February 22, 2010Date of Patent: August 6, 2013Assignee: Bendix Commercial Vehicle Systems LLCInventors: Duane R.
