    摘要： A hydromechanical transmission that can be used as a simple and efficient continuously variable transmission comprising a differential mechanism (4) for forming either a first high-speed mechanical transmission line (a) or a second low-­speed mechanical transmission line (b), a hydraulic power transmission mechanism (8) comprising two hydraulic pump/motors (5, 7), one of said hydraulic pump/motors being of the fixed displacement type, and the other is of the variable displacement type, and a mode selection mechanism for selecting either a low-speed mode or a high-speed mode in function of that mechanical transmission line (a, b) connecting the output shaft (19) to the input shaft (13).

    摘要： Disclosed is a nonstep speed change gear capable of selecting low speed mode and high speed mode by the low speed side clutch (14) and high speed side clutch (15), comprising a differential mechanism (4) having a low speed side mechanical transmission line (a) and a high speed side mechanical transmission line (b) formed in parallel, and a fluid transmission mechanism (12) forming a pair of fluid transmission lines (A, B) of which speed is variable by fluid pump/motor (7, 8) being installed on the way of these mechanical transmission lines, in which when the rotation speed difference of the both clutches becomes close to zero, the operation falls into intermediate lock-up mode so that the both clutches are connected together, and in this mode the displacement of the fluid pump/motor (7) is controlled by the control mechanism (51) so that the differential pressure of the circuits of the fluid transmission lines may be nearly zero.

    摘要： A stepless speed reducer includes the mechanical power transmission lines for high speed (15) and low speed (14), either line being selected to effect power transmission. When the working speed ratio comes near a predetermined critical speed ratio, the operation is maintained at the critical speed ratio while the pump motor (8) for low speed is kept inoperative and no pressure difference exists between the transmission circuits (31a, 31b), thereby transmitting power through the line for high speed (15).

    摘要： A hydromechanical transmission that can be used as an efficient continuously variable transmission, having a pair of speed sensors (24a,24b) for detecting the rotational speeds of the transmission ends (18,22) of two mechanical transmission lines (a,b) formed in the transmission, a pair of torque sensors (25a,25b) for detecting the torques transmitted by both said mechanical transmission lines, an actuator (27) connected to one reversible hydraulic pump/motor (7) of a hydraulic power transmission mechanism (8) cooperating with said mechanical transmission lines (a,b) and a computer (28). The computer (28) controls the actuator (27) and two clutches (21,23) in such a way that the system is switched from a low-speed mode to a high-speed mode and vice-versa without producing shock.

    摘要： Acceleration modulatorfor a hydraulic driving system of an automotive vehicle comprising an accelerator pedal, an engine whose output varies with the amount of operation of the accelerator pedal as transmitted to the fuel control terminal of the engine, a hydraulic pump driven by the engine, a hydraulic motor for driving the wheels of the vehicle, and a hydraulic circuit for transmitting the hydraulic pressure output from the hydraulic pump to the hydraulic motor; the acceleration modulator comprising: a wire for transmitting the operation of the accelerator pedal to the fuel control terminal of the engine of the driving system, the wire comprising a first portion and a second portion; a differential gear mechanism having a first input terminal connected to the first wire portion, a second input terminal, and an output terminal connected to the second wire portion, the differential gear mechanism being so arranged that a movement of the first wire portion transmitted to the first input terminal is modulated differentially by a displacement of the second input terminal so that the modulated movement is taken out at the output terminal; and a fixing mechanism for variably fixing the position of the second input terminal of the differential gear mechanism, the fixing mechanism being so arranged that when the hydraulic pressure in the hydraulic circuit of the driving system rises to a preset level slightly lower than the relief pressure of the hydraulic circuit, the second input terminal of the differential gear mechanism is moved to a posi-- tion where the amount of output from the differential gear mechanism decreases.
