Transmission apparatus (416) includes an input shaft (426) adapted to receive energy from the power source and an output shaft (434) adapted to transfer energy to the work device. Preferably, transmission apparatus (416) further includes a fluid coupling (25) configured to transfer energy from input shaft (426) to output shaft (434) and a mechanical coupling (24) configured to transfer energy from input shaft (426) to the output shaft (434).
摘要:
A power transmission apparatus for vehicles for transmitting a driving force by coupling an input shaft (1) and an output shaft (2) of a hydraulic pump (3) to respective driving shafts of front and rear wheels of a four-wheel drive vehicle, wherein a throttle member (60) which is located on the axis of a rotor (30) and a casing interlocking respectively with the input and output shafts (1, 2), rotated with interlocking with one of the rotor (30) and casing and disposed movably along the axis to change the hydraulic fluid discharge passage area of the hydraulic pump (3) responsive to its movement, and a driving unit which includes a magnetic member (63) coupled coaxially to the throttle member (60) and a coil installed around the magnetic member (63) and supported nonrotatably, and moves the throttle member (60) by movement of the magnetic member (63) in connection with excitation of the coil (7) are provided.
摘要:
A hydraulic transmission coupling apparatus which is used instead of a center differnetial or a viscous coupling being usually mounted between a front wheel drive shaft (1) and a rear wheel drive shaft (2) of a four-wheel drive vehicle, and transmits driving force existing between the two shafts. The hydraulic transmission coupling apparatus is provided with a vane-type hydraulic pump (3) which generates hydraulic pressure corresponding to a relative rotation speed difference of the two drive shafts (1,2) and a variable throttle valve (5) being disposed in the passage (48) connecting a discharge port of the hydraulic pump (3) with a tank (T), whose opening area varies according to the hydraulic pressure generated by the hydraulic pump (3), thereby driving force to be transmitted being increased or decreased steeply as the rotation speed difference becomes larger.

Die Vorrichtung dient zur Übertragung einer Drehbewegung von einer Motoreinheit (2) auf eine Verbrauchereinheit (3) und hat eine mit der Motoreinheit (2) verbundene Welle (11) und eine mit der Verbrauchereinheit (3) verbundene Welle (12), welche starr mit einem gehäuseförmigen Körper (52) verbunden ist, der in seinem Inneren eine Kammer (17) aufweist und wenigstens eine Öffnung (25, 26, 33, 34) hat, welche mit der Kammer (17) und mit dem Raum außerhalb des gehäuseförmigen Körpers (52) verbunden ist. Die mit der Motoreinheit (2) verbundene Welle (11) ist starr mit einem Pumporgan (14, 15, 16) verbunden, das sich in der Kammer (17) befindet und im Betrieb ein Medium durch die Öffnung (25, 26, 33, 34) in die Kammer (17) zurückführt, wenn wenigstens eine der Wellen (11, 12) rotiert. Die Kammer (17) ist mit wenigstens einer Durchlaßbohrung (39) verbunden, welche eine Verbindung zu dem genannten Außenraum herstellt. Über eine Ventileinrichtung (40) kann die Durchlaßbohrung (39) steuerbar mit dem Außenraum verbunden werden.
摘要:
A clutch device separates a non-changing component and a changing component of power generated by a driving source, and transmits the non-changing component and the changing component of power so separated to separate driven bodies, respectively. Power generated by a driving source (4) is preferably subjected to form conversion by power form conversion means and is then separated into a non-changing component and a changing component by power separation means. The non-changing component of power so separated is transmitted to a first driven body (6) by non-changing component transmission means while the changing component of power so separated is transmitted to a second driven body (B) by changing component transmission means. A fluid pump (1) can be used as the power form conversion means, and an outlet flow rate regulating valve (3) of the fluid pump (1) can be used as the power separation means. Control of the second driven body (B) can be made easily by smoothing the changing component of power using smoothing means (34).
