Patent number: 10487566Abstract: A system for transferring torque with zero lash from a driver to a driven object is provided. The system includes a shaft disposed about a rotational axis and a hub defining a bore that receives the shaft. The shaft and hub are each configured for coupling to one of the driver and driven object. The shaft defines a flat on a radially outer surface and the hub defines a flat on a radially inner surface opposing the flat in the shaft. In one embodiment, the shaft includes a threaded bore and the hub includes an aligned through bore. Rotation of a threaded fastener in the bores draws the flat into engagement. In another embodiment, the hub includes a threaded through bore. Rotation of a fastener extending through the bore and engaging the shaft diametrically opposite the flats urges the flats into engagement.Type: GrantFiled: September 14, 2017Date of Patent: November 26, 2019Assignee: Bendix Commercial Vehicle Systems LLCInventors: Mark H. Sciulli, Jeffrey J. Krause, Timothy J. Beckwith, Thomas W. Grieve, John J. Drabczyk, William A. Singleton, Dustin Carpenter, Cody Scibetta

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. Johnson, Rebecca Carter, Mark H. Sciulli, Scott R. Weslow, Timothy J. Beckwith

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. Johnson, Jeffrey J. Krause, Mark H. Sciulli

Patent number: 6886860Abstract: A steering column assembly that includes a steering column, and a bracket for mounting the steering column to the dashboard of a vehicle; and an adapter detachably connected to the steering column for providing an interface for mounting a plurality of items on the adapter. The bracket further includes a tongue and the adapter further includes a notch for engaging the tongue such that the adapter can be mounted on the steering column in only one orientation. The adapter component of the present invention further includes a plurality of surfaces for mounting various items on the adapter. The adapter may be easily modified to accommodate different system devices or other items.Type: GrantFiled: August 13, 2002Date of Patent: May 3, 2005Assignee: Bendix Commercial Vehicle Systems, LLCInventors: William A. Singleton, Scott R. Weslow, Mark H. Sciulli
