    摘要: A method for controlling automatically controlling the shifting of a transmission when operating the higher speeds so that a downshift is performed before a directional shift is made. A controller receives a directional signal, a mode signal, a transmission output speed signal. The signals and a shift sequence table is used to shift the transmission when the machine has reached an "on speed" point. The controller will perform a shift after a predetermined time without the machine reaching the "on speed" point.

    摘要: Vehicles (12) having implements (14) are typically used to perform repetitive functions in work cycles. Advantageously, such vehicles (12) include control systems (10) for maintaining a control lever (26) in a predetermined position until an associated work cycle function is completed. The subject control (10) includes a rocker bar (46) connected to the control lever (26) and a solenoid (50) having an actuator rod (52) disposed adjacent the rocker bar (46). The control (10) energizes the solenoid (50) to hold the control lever (26) in the predetermined position in response to a position of the implement (14), a position of the control lever (26), and a desired kickout position.

    摘要: A system is provided for operating a fan to move air past a heat exchanger. The fan is driven by hydraulic fluid supplied from a pressure compensated pump. Such fluid driven fan systems are commonly utilized on industrial vehicles and on stationary engines having fluid type systems. The system controllably operates the fan at relatively high speed in response to the temperature of least one of the fluid coolant and hydraulic fluid being greater than respective first and second predetermined upper temperature values, and controllably operates the fan at a second relatively slow speed in response to the temperature of each of the fluid coolant and hydraulic fluid being less than respective first and second predetermined lower temperature values. The system also controllably continues to operate the fan at the instant fan speed in response to the temperature of at least one of the fluid coolant and hydraulic fluid being between the respective first and second predetermined upper and lower temperature values and to neither of the fluid coolant and hydraulic fluid temperatures being greater than the respective first and second predetermined upper temperature values.

    摘要: An anti-spin apparatus for a machine is disclosed. The machine is articulated and has at least one axle set with at least two driven wheels. The anti-spin apparatus includes braking mechanisms which controllably apply braking forces to each of the driven wheels. A controller produces a slip signal having a value responsive to the difference in rotational velocity between the wheels of the axle set. A transducer produces an articulation signal having a value responsive to the angle of articulation of the machine. Further, a microprocessor receives the slip signal and the articulation signal, and produces a braking control signal. One of the braking mechanisms receives the braking control signal and responsively applies the braking forces to the faster rotating wheel.

    摘要: A method for controlling an apparatus (100) for controllably moving an implement (102) is provided. The implement (102) is connected to a work machine (104) and is movable between first and second implement positions in response to operation of a hydraulic actuator (106). The apparatus (100) includes a joystick (306) with first and second positions and a neutral position. The joystick (306) is normally biased in a neutral position and is movable between the first and second positions. The apparatus senses the position of the joystick (306) and responsively generates a joystick position signal. The joystick (306) maintained at the first and second detent positions in response to manual movement of the joystick to the respective first and second detent positions. The joystick (306) is released from the detent position in response to receiving a release detent signal. The apparatus (100) senses the position of the work implement (102) with respect to the work machine (104). The apparatus (100) provides hydraulic fluid flow to the hydraulic actuator (106) in response to a magnitude of an electrical valve signal. The apparatus (100) receives the joystick position signal, responsively delivers the electrical valve signal. The magnitude of the electrical valve signal is proportional to the joystick position signal. The apparatus (100) compares the implement position signal with a first detent position and a second detent position and responsively produces the release detent signal.
