    摘要: A gear for motor vehicles provided with a positive-displacement pump for supplying a lubricating device and the control and activating devices of the gear. The positive-displacement pump is driven by the rotation of a drive motor and is provided with a suction throttle which adjusts the flow of lubricating oil such that a relatively constant flow is maintained over a varying range of rotational speeds of the drive motor. The invention provides the advantages that gear efficiency can be improved since high rotational speeds of the drive motor do not cause a excessive flow of lubricating oil.

    摘要: The invention concerns a transmission (1) with automatic shifting capabilities and with three spider supported planetary sets (2, 3, 4), three brakes (5, 6, 7), and two clutches (8, 9) for the shifting of six forward moving gears and one reverse gear and having an input shaft (10) and an output shaft (11). In this way, the input shaft (10) is in continual connection with the sun gear (16) of the second planetary set (3) and the input shaft (10) is connectable to the sun gear (12) of the first planetary set (2) by means of the first clutch (8) and/or by means of the second clutch (9) is also connectable with the spider (15) of the first planetary set (2). Further, the sun gear (12) of the first planetary set (2) by means of the first brake (5) and or the spider (15) of the first planetary set (2) by means of the second brake (6) and/or the sun gear (20) of the third planetary set (4) by means of the third brake, are all connectable with the housing of the transmission.
