This invention provides both a pump and a lubrication and cooling system with a pump which includes a pump housing, a rotor, a relief valve and a bypass valve. The relief valve is configured to relieve pump pressure when the pump pressure is indicative of an abnormal restriction of flow. The bypass valve is configured to direct fluid flow from an outlet chamber of the pump to an intake chamber of the pump when pressure in the outlet chamber is at a value associated with a predetermined speed of rotor rotation.

Transmission pump

Disclosed is an exemplary transmission clutch fork position sensor including an elongated bar and a clutch fork slidably engaging the elongated bar. A yoke bar includes a first end coupled to the clutch fork for concurrent movement therewith. A position sensor operably engages the yoke bar, and is operable for detecting a position of the yoke bar.

A continuously variable transmission (CVT) is suitable for replacement of a main transmission box of a compound transmission in a light to medium duty electromechanically actuated truck transmission system. For example, one line-haul truck transmission consists of a five-speed main section and an auxiliary deep reduction box to provide 15 forward speed ratios. The replacement of the five-speed main section with a CVT unit enhances the overall operating efficiency of the system. In one form, the CVT includes a pair of rotatable countershafts mounted to pivot relative to one another. Each of countershafts has a greater diameter disk at one end than the other. Positioned between countershafts are a pair of laterally spaced cones that share a common axis; the greater diameter disk ends of the two countershafts bear against one of the intermediately positioned cones, while smaller diameter disk ends of the countershafts bear against the second cone.

Floating cone continuously variable transmission

A controller-assisted, manually shifted transmission system ( ) utilizes a shift inhibit mechanism ( ) to inhibit out-of-synchronous shifts and unintended disengagement of ratios. An intent to shift (ITS) and target ratio (GR ) are determined from a shift lever position sensor ( ) and a force sensor ( ).

System/method for synchronized shifting of a manually shifted transmission

A control for enhanced manual shifting in a computer-assisted (48) vehicular splitter-type compound transmission (16) having a synchronized main section (16A) shifted by a manually operated shift lever (31) and a controller (42). The splitter section (16B) is located at the input end of the transmission, is provided with a three-position (L, H, N) actuator (46), and is commanded to a splitter-neutral position upon sensing an intent for a main section shift to neutral and remains in splitter neutral until the main section is reengaged to reduce the forces required to synchronize the main section.
