Abstract: A spring designed to be mounted adjacent and in conformance with a convex or concave surface that has varying radii of curvature. The stiffness against bending of the spring varies along its longitudinal axis. The stiffness against bending of various portions of the spring is proportional to the radii of curvature of portions of the surface adjacent which each portion of the spring is to be disposed. The mounting structure for the spring includes female mounting members that are to be engaged to male mounting members. The female mounting members and male mounting members can be engaged to one another by sliding the two components together. The spring and mounting system are particularly well adapted for holding objects adjacent an inner surface of body panels of a vehicle.

Abstract: The invention provides a dual release system for a slam lock to a luggage compartment door for a vehicle. The slam lock, as is conventional, includes a catch and a latch bar. The catch is installed on a surface of the luggage compartment adjacent the door. The latch bar is mounted through a lock cylinder, which is in turn mounted through opposite major sides of the door to bring the latch bar into engagement with the catch when the door is closed. The latch bar is spring biased to releasably engage the catch. The lock cylinder is accessible by key from the major side of the door on the exterior of the vehicle, and is actuable to move the latch bar to a released position relative to the catch. A release cable within the vehicle is attached to the latch bar to pull the latch bar to the released position relative to the catch.

Abstract: A single air spring positioned under one side of a vehicle provides side to side leveling of the vehicle. Main springs support the vehicle above a pair of coaxial wheels or coaxial wheel sets. An auxiliary, inflatable air spring is positioned to provide additional support to the vehicle above one of the wheels. Deflection of the main springs from a norm or index is indicated by movement of tie rods mounted from the wheels, axle, or base of the main springs relative to the suspended portion of the vehicle. One tie rod is directly linked to a free end of an equalizer lever whereby the equalizer lever moves in the same direction as the tie rod. The second tie rod is coupled to the remaining free end of the equalizer lever by a rotatable rod, whereby the appropriate end of the equalizer lever moves in the direction opposite to the tie rod. The equalizer lever is suspended at its center from an actuation lever for a valve used to control inflation and deflation of the auxiliary air spring.

Abstract: A suspension system for a vehicle frame from a steering axle has first and second controllable rate springs mounted above the steering axle and below the frame to support a portion of vehicle weight. A trailing V-link member is mounted to pivot on its vertex on a cross-member of the frame forward of the steering axle. The opposite ends of the V-link member are pivotally connected to opposing ends of the steering axle allowing the V-link member to constrain fore to aft movement of the steering axle, lateral displacement of the steering axle and frame roll. A pitman and trailing draglink from a steering gear on the frame to the steering axle controls steering. First and second shackle assemblies depend from the frame aft of the steering axle. First and second leading arms are suspended from the shackle assemblies to permit longitudinal translation of the first and second leading arms relative to the frame.

Abstract: The present invention describes a filter screen for removing debris from the hydraulic actuating fluid in an internal combustion engine having a hydraulic pump for supplying hydraulic actuating fluid to hydraulically-actuated unit fuel injectors. An upper portion of a priming reservoir is mounted on a front cover of the engine. The front cover forms a lower reservoir portion. A screen assembly is positioned adjacent to an interface defining an entrance from the upper reservoir portion to the lower reservoir portion. The screen assembly includes a filter screen enclosing the entrance to force the actuating fluid to pass through the filter screen, thus retaining debris that exceed the mesh size of the filter screen.

The antenna may be installed as original equipment or as a back-fit part in the after-market. In either case the multi-functional antenna will be integrated with the vehicle's multiplexed electronic component communication system.

Abstract: A mounting arrangement for a modular component such as a fuel tank for a vehicle such as a truck and a method of installing same on the vehicle. The method is accomplished via a combination of a set or sets of two brackets and an initial alignment means for each set of brackets. The initial alignment means is comprised of two mating components, with one mating component being a portion of one bracket and the other mating component being a portion of the second bracket. One bracket of each set is installed directly to a portion of the vehicle under manufacture, such as to the frame rail. A modular assembly is assembled separately with the second bracket of each set installed on the modular assembly. The sets of brackets are joined via the initial alignment means attaching the modular assembly to the vehicle.

Abstract: A push-to-connect tubing fitting which has a body, a collett with tubing gripping teeth that engage the tubing, and sealing devices. The collett is disposed within a bore in the body of the fitting. The collett has tubing gripping teeth on its inner bore which mechanically engage the outer surface of the tubing. A first sealing device is positioned within an inner bore of the collett at a point closer to the tubing insertion opening of the collett than are the tubing gripping teeth. This first sealing device seals the tubing to the collett. A second sealing device is disposed between the collett and the body. This second sealing device seals the collett to the body of the fitting and effectively completes the seal between the tubing and the body.

Abstract: An occupant compartment of an automotive vehicle contains an instrument panel to the rear of which an occupant of the vehicle may be seated. A knee bolster is disposed below the instrument panel frontally of the occupant's knees and has a through-opening toward the occupant. A movable cover selectively closes and opens the through-opening. When the cover is closed, it covers a key that was inserted into the vehicle ignition switch and turned to operate the switch to turn on the engine while the cover was open. The ignition switch is disposed in a mounting that extends outward when the cover is opened to render the switch accessible for key insertion, key operation, and key removal. When the cover is closed, the mounting and switch retract within the knee bolster.

Abstract: A one-piece mounting bracket (30) for mounting an automatic transmission shift control in the cab of a truck has a top wall (34) and laterally spaced apart side walls (36, 38) depending from the top wall and extending rearward into covering relation to laterally opposite sides of the shift control. A face plate (70) spans the side walls of the bracket in covering relation to the shift control, and a shift lever (62) for operating the shift control to shift the transmission extends from the shift control through an opening (72) at the face plate to provide a grip by which a driver of the vehicle can operate the shift control. The side walls are symmetric about an imaginary medial plane that perpendicularly bisects an imaginary plane occupied by the top wall. The side walls also have symmetric hole patterns (50, 52) providing shift cable attachment features that are symmetric about the imaginary medial plane. The bracket may be used in either a right- or left-hand drive vehicle.

Abstract: An apparatus for operator controlled purging of the tanks of a pressurized air reservoir of a vehicle air system comprises an air actuated normally closed drain valve mounted to an underside of each tank, a source of pressurized air engaged to each drain valve, and a controller for each valve engaged downstream of the source, and within a driver area of the vehicle, the controller when activated, allowing for communication between the source and the drain valve for opening of the valve. The method for using the apparatus in testing air system integrity includes the steps of draining and refilling each tank individually in a pre-defined sequence while monitoring driver area mounted indicators of air pressure levels and testing functionality of an air system operated service brake system of the vehicle by carrying out the pre-defined sequence.

Abstract: A control system for vehicle accessories differentiated from one another in terms of required voltage, current drawn, load duration and variability of energization levels utilizes generic interface modules to effect control. One or more generic remote interface modules, in addition to controllers such as engine and chassis controllers, are mounted on the vehicle for controlling actuation and energization of the non-standard devices, such as motors driving pumps for hydraulic lits. An electronic system controller (ESC) manages the remote interface modules over a serial communication link to provide the specialized functionality. Each remote interface module (RIM) is constructed as a standard component capable of providing digital and analog outputs to devices attached to one or more output ports on the module. The remote interface assumes a number of controller states under the control of the electronic system controller for regulating actuation and energization of the differentiated loads.

Abstract: A dash reinforcement for a mobile vehicle with a passenger cab such as a sport utility vehicle, or medium or heavy-duty truck. The dash reinforcement may be a stamped sheet metal panel that strengthens the dash structure of the cab and provides for mounting of vehicle components. The dash reinforcement may be symmetrical about the centerline of the vehicle and this symmetry allows the panel to accommodate both left-hand drive and right-hand drive vehicle configurations. The dash reinforcement also includes ‘Y’ shaped passages for a driver control module and for accessory equipment such as heating, ventilation, and air conditioning (HVAC) modules. The unique shape of these passages or openings adds strength to the overall dash structure and hence the cab. The dash reinforcement may be engaged to a dash panel to form a dash assembly.
