Abstract: A control system for controlling both a lean combustion engine equipped with a swirl control valve and an automatic transmission. The control system includes a shift detector for detecting that a shift is being executed in the automatic transmission and a valve control inhibitor for inhibiting the switching the ON/OFF state of the swirl control valve in the course of the shift in the automatic transmission. A shift inhibitor inhibits the shift for a constant time period in case the ON/OFF state of the swirl control valve is switched. A regulation level changer changes the regulation level of the oil pressure of the automatic transmission in accordance with the ON/OFF state of the swirl control valve.

Abstract: A motion transmitting remote control assembly (10) of the type for transmitting motion along a curved path by a flexible motion transmitting core element (14) movably supported within a tubular conduit (12) includes a first (18) and second (20) conduit section axially moveably disposed with respect to one another. A release pin (106) is disposed between the first (18) and second (20) conduit sections for maintaining the first (18) and second (20) conduit sections in a minimum length position while the assembly is shipped and installed. A compression spring (82) reacts between the first (18) and second (20) conduit sections for automatically urging the first (18) and second (20) conduit sections to a maximum length position upon removal of the release pin (106). A locking clip (86) maintains the assembly in the adjusted position.

The pin and/or the notch each includes a nonvertical contact surface. In one version of the device, the notch includes an S-shaped contact surface.

Abstract: An actuator suitable for use with a valve has a design allowing for easy control or adjustment of the force applied to the valve. The actuator motor has a cam which operates a follower surface of a spring-loaded arm mounted for rotation on a carriage. The carriage is mounted for linear motion and connected to the control element of the valve. The actuation force can be controlled or adjusted by changing the relative positions of the arm's center of rotation, the point on the arm at which the spring applies force, and the position of the cam. In a preferred embodiment, the position of the arm's center of rotation is changed by moving a pin from one set of holes in the carriage and the arm to a second set of holes in the carriage and the arm.

Abstract: A clutch wheel for a plate type friction clutch comprises a clutch disc carrying a plurality of friction pads spaced coaxially around it. Each friction pad consists of two pad elements arranged back to back and movable axially with respect to each other against the action of a Belleville ring inserted between them. This axial movement is controlled within predetermined limits by abutment means consisting of cooperating elements of the two friction pads, or of at least one of the friction pads and the clutch disc. The Belleville ring is precompressed in such a way that, within the limits of the axial movement defined by the abutment means, it works only on a part of its characteristic curve in which the reaction force which it exerts is substantially constant.

Abstract: An improved braking mechanism (100) is provided for use in conjunction with a change gear transmission (50) that is selectively engagable with a vehicle engine (4) by a clutch (3). Mechanism (100) has a piston (22) slidably received in a primary fluid chamber (34) that is operative to cause mechanism (100) to act as an inertia brake upon establishment of a first set of predetermined operating conditions. Piston (22) is also slidably received in a secondary fluid chamber (36) that is operative to cause mechanism (100) to act as a hill holding brake upon establishment of a second predetermined set of operating conditions.

Abstract: An engine-rpm-dependent arrest device to prevent non-permitted down shifts in motor vehicle transmissions containing a pilot valve (1) and a control valve (2), both having two shift positions. One shift position of the control valve (2) is engaged by the pressure acting upon a piston surface (36) of the control-valve piston (31) and exceeding a given value of an engine-rpm-dependent low-pressure pump (20). The control valve (2) is exclusively in contact with the pressure medium conveyed by the low-pressure pump (20) and controls the large end surface (40) and the annular surface (41) of a pilot-valve piston (38) designed as stepped piston. If when the high gear is engaged and the engine rpm is above a certain limit value, the gear-shift valve (7) is moved to its position for low gear, then an actuation of the actuation device (15) for the low gear is prevented via the pilot valve (1).

Abstract: A method of controlling a friction type clutch of a vehicle having an engine and a drive train, which clutch is operated by hydraulic oil and is frictionally engageable to transfer rotational driving force from an output shaft of the engine to the drive train, includes the steps of causing the clutch to assume a slipping state of engagement upon starting of the vehicle, and defining a first amount of time as a function of the temperature of the hydrauilc oil. When the first amount of time has elapsed since the starting of the vehicle, the clutch is positively urged from slipping state of engagement into a locked up state of engagement.

Abstract: The outputs (17-18) of a pair of intermittence devices (16) operated in phase with a clutch driving shaft (6), clutch however, generate equal movements, however in a 180.degree. out-of-phase relation with each other. With the interposition of respective electromagnetic friction clutches (27-28), these outputs are connected to the driven disc of the clutch. The two clutch discs are normally interconnected by at least one respective dog (9-10). A control logic (22) connected to a generator of clock signals (K1-K2) in phase with the uniform motion and rest times of the outputs from the intermittence devices, commands the clutch to be opened and closed, when the friction clutch at the selected output is closed, and when the said output travels at the same speed as the input into the intermittence devices.

Abstract: The rotational speed of an engine Ne and a drum rotational speed Nt of a clutch Cl are compared against each other to determine a power on/off. For a 2.fwdarw.3 and a 2.fwdarw.4 shift in the power off condition, a timing solenoid SL5 is turned on (duty cycle of 100%) to accelerate the termination of a preceding speed range, thus increasing a time delay between such termination and the activation of a new speed range to be established. For other shifts, a time difference between the termination of a preceding speed range and the activation of a new speed range to be established is adjusted, by energizing the solenoid SL5 in accordance with the throttle opening .theta. and the vehicle speed No such that SL5 is energized with a high duty cycle for a longer .theta. and with a low duty cycle for a smaller .theta..

Abstract: The present invention provides an apparatus for controlling a hydraulic pressure usable for a clutch wherein the appratus is employed for a transmission mounted on a construction machine or the like in such a manner that it is provided separately for a plurality of clutches 1 and it is controlled individually. The apparatus includes a first valve 3 for allowing a large amount of hydraulic oil to flow in the clutch and a second valve 4 for electronically controlling a clutch pressure so that the termination of filling and the clutch pressure are detected by a simple structural arrangement on the basis of a displacement of a spool 21 for the first valve 3 and a separately disposed piston. In addition, appearing of an overshoot pressure on the termination of filling is prevented by providing a difference in pressue receiving areas on the spool 21 for the first valve.

Abstract: A relatively simple electromechanical cruise control for a vehicle includes a hydrostatic drive linkage having a flat portion connecting two links and extending adjacent an electromagnet fixed to the frame of the vehicle. Actuation of the control under preselected operating conditions activates the electromagnet to hold the flat portion stationary and thereby maintain a given hydrostatic control position. Interlock circuitry deactivates the magnet if the operator touches the brake, leaves his seat or turns off either the cruise switch or ignition switch.
