Publication number: 20160195093Abstract: A flow monitoring device is coupled to a case drain of a hydraulic pump. The flow monitoring device includes a manifold to receive a fluid flow from the case drain. The manifold has an inlet, a throat and an outlet. The manifold includes a pressure sensor to measure a differential pressure of fluid between the inlet and the throat. The manifold further includes a temperature sensor to measure a temperature of fluid flowing through the manifold. A bypass passage is fluidly coupled between the inlet and the outlet of the manifold. A bypass valve located in the bypass passage regulates an amount of fluid flowing from the inlet to the outlet of the manifold through the bypass passage.Type: ApplicationFiled: March 11, 2016Publication date: July 7, 2016Applicant: Caterpillar Inc.Inventors: Richard A. Carpenter, Peter Dubenco, Stephen J. Morey

Patent number: 5459658Abstract: An apparatus is provided for use in a vehicle having an engine driven transmission which includes a plurality of gear ratios. The apparatus includes a sensor adapted to sense an operating parameter and responsively produce a parameter signal. A memory device includes a custom shiftpoint map for storing data which relates transmission gear ratio to the parameter signal. A programming device for allowing the custom shiftpoint map to be reprogrammed during vehicle operation. A controller is adapted to receive the vehicle speed signal, retrieve data from the custom shiftpoint map, and process the retrieved data and the parameter signal to produce a transmission control signal. An actuator is adapted to receive the transmission control signal and responsively control the transmission gear ratio.Type: GrantFiled: June 22, 1992Date of Patent: October 17, 1995Assignee: Caterpillar Inc.Inventors: Stephen J. Morey, Rick D. Vance, Steven T. Ufheil
