Abstract: A source of liquid provided an input of liquid into a liquid cooling system. The liquid from the source of liquid flows through a check valve assembly which includes an input, a first output, and a second output. The second output includes a check valve configured to open when the pressure of the liquid exceeds a threshold pressure value. A connector is attached to the first output of the check valve assembly. The connector is a quick connect fitting equipped with a self-sealing valve.

Abstract: A range determination apparatus for preventing a shift range from being undefined during speed change states of an automatic transmission with no manual valve. The range determination apparatus includes a gear speed change mechanism and a plurality of friction engagement elements operative to have respective operation states changed between an engagement and a disengagement state. The range determination apparatus is used for automatic transmissions subject to speed changes via a torque transmission path of the gear speed change mechanism changed by the operation states of the friction engagement elements. A real shift range determination is carried out on the basis of the operation states of the friction engagement elements, where a T-ECU is operative to determine a current shift range based on detection results obtained by oil pressure sensors and operation patterns preliminarily memorized when the operation states of the friction engagement elements are not being changed.

Abstract: A cylindrical pressure-receiving member 34b is arranged in a space between a ring-shaped clamp sleeve 34a and a frame 31b such that the clamp sleeve 34a is fitted around a shaft 38b being integral with a rotary shaft 39. In an outer peripheral portion 34a2 of the clamp sleeve 34a, an annular groove 34a1 provided continuously over the entire circumference within an axial area of the outer peripheral portion 34a2 fitted into an inner peripheral portion 34b3 of the pressure-receiving member 34b provides a thin-wall portion 34a5. Also, a space surrounded by the annular groove 34a5 and the pressure-receiving member 34b provides a pressure chamber 34d communicating with a fluid control circuit. A predetermined gap 34d2 is provided between an inner peripheral surface 31b4 of the through hole 31b1 of the frame and an outer peripheral surface 34b2 of the pressure-receiving member 34b.

Abstract: A solenoid pump and associated hydraulic circuitry are intended for use in automatic transmissions capable of engine start stop (ESS) operation. In a first embodiment, a solenoid pump provides pressurized hydraulic fluid to respective inputs of two way check valves. The other inputs are provided with controlled hydraulic fluid from a transmission valve body. The outputs of the check valves are provided to those hydraulically operated torque transmitting devices associated with first gear. The solenoid pump is activated when the transmission is in gear and the engine is stopped to maintain hydraulic pressure in those actuators associated with first gear in order that a first gear vehicle launch may be quickly and smoothly achieved when the engine is restarted. A second, similar embodiment provides hydraulic fluid to actuators associated with reverse gear.

Abstract: A transmission for a vehicle with a clutch and/or a brake which is hydraulically actuated by a cylinder and a piston actuator. A pressure chamber is located between the cylinder and the piston and a hydraulic pressure medium flows into the pressure chamber via an inlet. The pressure medium is supplied to the pressure chamber via a component fixed on the housing, a rotary passage between the fixed component and the rotatable component and then via the rotatable component. The radial distance of the radial middle of the rotary passage is larger than the smallest radial distance and smaller than the largest radial distance of the pressure chamber from the rotation axis of a central shaft of the automatic transmission. The radial arrangement of the rotary passage, between the radially smallest and largest diameters of the pressure chamber, neutralizes centrifugally generated forces on the pressure medium in the pressure chamber.

Abstract: A brake assembly is activated by a vehicle brake. The brake assembly is mounted upstream from a transmission and either up or downstream from a clutch. A controller for the transmission brake allows the driver to adjust both a transmission brake lead/lag time and force relative to the vehicle wheel brakes.

Abstract: A method of improving the brake and clutch capacity of a functional fluid comprising adding a friction-modifying amount of a polyalkenyl sulfonate to the functional fluid, wherein the polyalkenyl sulfonate is an alkali metal or alkaline earth metal salt of a polyalkene sulfonic acid derived from a mixture of polyalkenes comprising greater than about 20 mole percent alkyl vinylidene and 1,1-dialkyl isomers.

Abstract: A start control device is provided for a vehicle that is subjected to neutral control for releasing a coupling element of an automatic transmission when the vehicle is stopped with predetermined conditions satisfied while the automatic transmission is in a forward drive position. The start control device detects a braking operation performed by the driver of the vehicle or a braking condition during the neutral control, and controls the braking force of the vehicle when the vehicle returns from the neutral control, based on the detected braking operation or the braking condition during the neutral control.

Abstract: A motion control system for controlling the motion of a crawler having a left and right track. The system comprises a pivotally mounted controller; a steering control system hydraulically communicable with a pressurized fluid supply, a brake of each of a left and right track of a crawler and a clutch of each of a left and right track of a crawler, a direction control system hydraulically communicable with a pressurized fluid supply, a forward and a reverse transmission signal input, a steering speed controlling system for controlling the speed of a left track and a right track, and a transmission gear controlling system.

The steering control system is positioned so that pivoting the controller in a first series of planes operates the steering control system.

Abstract: A slewing ring brake for use in heavy machinery including earthworking machinery. The slewing ring brake includes a slewing ring with a tooth system and a support member which is mounted in a manner to allow rotary movement of the support member relative to the slewing ring. The slewing ring brake also includes a brake block displaceably mounted on the support member, the brake block being displaceable between a braking position and a freewheeling position. In the braking position, the brake block engages with the tooth system thereby preventing rotary movement of the support member relative to the slewing ring.

Abstract: A control apparatus includes a detecting means (16) for detecting the position of an accelerator pedal (14) or an accelerator lever, a clutch (8) which is disposed between a diesel engine (1) and the mechanical supercharger (10), and a coupling/decoupling means (16) for coupling or decoupling a clutch (8) based on a signal from the detecting means (16). A control method includes the steps of detecting the stroke distance of the accelerator pedal (14) or the accelerator lever, and operating the mechanical supercharger (10) when the stroke distance detected ranges from a predetermined value in the vicinity of the full stroke to the full stroke. This improves responsiveness in the initial stage of acceleration, and obtains better normal running performance and better hill-climbing ability.
