Publication number: 20070203625Abstract: System and methods provide information to an operator of an engine such that the engine operates with optimal performance, such as maximal fuel efficiency. Such a system may include a plurality of sensors adapted to measure operating parameters of the engine; an engine management system adapted to receive measured operating parameters from the sensors and to generate signals indicative of a current operating performance of the engine and signals indicative of performance-increasing adjustments to current operating parameters; and a display adapted to present symbols in response to signals from the engine management system. The symbols guide the operator to increase or maintain engine performance.Type: ApplicationFiled: November 12, 2004Publication date: August 30, 2007Applicant: VOLVO TRUCKS NORTH AMERICA, INC.Inventors: Jon Quigley, Gregory Prinzo, Bo Hammerlid

Patent number: 7137656Abstract: A latch assembly for connecting a hood assembly to a truck includes a striker bolt that is surrounded by a sleeve that is engaged by a rotary latch. The sleeve is of shorter length than the striker bolt so that it can slide along the striker bolt. The rotary latch fixedly engages the sleeve so that any relative motion between the hood and frame translates to movement of the sleeve along the striker bolt rather than between the rotary latch and striker bolt. The sleeve arrangement thus provides wear protection to rotary latch, allows for self alignment of the hood and fender assembly along the striker bolt axis and dynamic movement of the latch during vehicle operation.Type: GrantFiled: April 23, 2004Date of Patent: November 21, 2006Assignee: Volvo Trucks North America, IncInventors: James D. Bird, Karl Duckett

Patent number: 7077413Abstract: Spring suspension for interconnecting an axle to the frame of a commercial, land-based and wheeled vehicle. An end support for an axle is included that has a cantilever spring interconnected by an interposed axle holder to an air-spring bridge. The cantilever spring extends forwardly; that is, toward the front end of the incorporating vehicle, from the axle holder. Oppositely, the bridge extends rearwardly from the axle holder. The forwardly extending cantilever spring elongately extends between two terminal ends thereof. These two ends constitute a front frame-secured end and a back axle holder-secured end. The rearwardly projecting bridge extends between its own two terminal ends, and constitutes a front axle holder-secured end and a back air-spring secured end. The front frame secured end of the cantilever spring is distantly positioned away from the back air-spring supported end of the bridge member.Type: GrantFiled: May 6, 2004Date of Patent: July 18, 2006Assignee: Volvo Trucks North AmericaInventors: Bjorn O.

Patent number: 7051851Abstract: A method and apparatus for controlling frame rise on a heavy duty truck having a frame, a drive axle connected to the frame, and a selectively lockable suspension component disposed therebetween for maintaining the relative position therebetween. Signals indicative of at least one of the following vehicle operating parameters: engine speed, brake pressure, vehicle speed, air bag pressure, steering wheel angle, vehicle height, or throttle position are monitored and a predicted thrust is calculated that will be applied to the drive axle based on the monitored signals. The selectively lockable suspension component is locked if the predicted thrust exceeds a predetermined threshold and is also controlled with respect to other operating parameters such as whether vehicle brakes are applied, any instantaneous change in torque, vehicle operating speed, and the length of time the selectively lockable suspension component has been locked.Type: GrantFiled: November 4, 2002Date of Patent: May 30, 2006Assignee: Volvo Trucks North America Inc.Inventors: Bjorn O.
