    摘要： The device is so designed as to be cheap enough to be sold in large numbers and is particularly simple, compact and has a very low power consumption. It comprises a hydrokinetic converter and a gear mechanism having two forward speeds established by means of two pairs of pinions. It is completed by two clutches and a free-wheel disposed in the converter which provide the connection with the two input elements of the mechanism. These two clutches are actuated by a single slidable plate which moves as a function of parameters such as the speed of the vehicle or the load on the engine. The two clutches are disposed on opposite sides of the plate and one clutch is connected in parallel with the free-wheel.

    摘要： A hydraulic-mechanical transmission that permits any desired relative rotation of the driven shaft relative to the driving shaft to be obtained, including a one to one transmission of power. The transmission includes a driving shaft that rotatably supports a housing in which at least one first circular endless confined space is defined in which a first hydraulic fluid is contained and that is subjected to a pumping action by a number of movable elements. The driving shaft has a sun gear rigidly secured thereto, which sun gear is in engagement with a number of circumferentially spaced planetary gears. Each planetary gear is rigidly secured to a first shaft that is journaled in the housing, and each first shaft being operatively associated to a pumping element. The pumping elements are actuated when the planetary gears rotate relative to the sun gear. The planetary gears are in toothed engagement with a ring gear that is rigidly secured to a driven shaft assembly. A number of rotatable valve members are supported in the housing to restrict the flow of the first hydraulic fluid in the first confined space to a desired degree. The greater the degree of such restriction, the more power is required for the pumping elements to move, and consequently, the driving shaft delivers torque to the driven shaft assembly at an increased magnitude. By rotating the valves in an opposite direction, the reverse effect is achieved, and the driving shaft delivers less torque to the driven shaft assembly. By placing the valves in a completely closed position, a one to one ratio between the rate of rotation of the driving shaft and driven shaft assembly may be obtained. Control of the rotatable valves may be either by manual means or automatically by centrifical means that are responsive to the rate of rotation of the housing, with the mode of control of such rotatable valves being the primary subject matter of the present invention.
