    摘要: The invention concerns a transmission, especially for a motor vehicle, which is designed as group transmission (1). In order to utilize as fully as possible the traction-speed diagram, the transmission has five manually shiftable gears to which join two automatically engageable and disengageable overdrive gears. The group transmission (1) is formed by one synchronized transmission (2) and one powershift transmission (3) . The proposed transmission stands out in particular by a light weight and small installation space at a low cost of production.

    摘要: The invention concerns a continuously variable transmission having a driving and a driven shaft (1, 9) and first and second intermediate shafts (10, 11). Power is transmitted to the driven shaft (9) through a transmission variometer with i.sup.2 arrangement. According to the invention, the input power of the transmission is transmitted to the driven shaft through a transmission branch with constant ratio and through the continuously variable transmission branch. This power distribution reduces the proportion of the power transmitted through the continuously variable transmission branch. The transmission efficiency of the whole transmission may, in particular, be thus improved. This continuously variable transmission is designed for use in private cars and light utility vehicles.

    摘要: A planetary gear transmission having four or five forward speeds and which comprises three planetary gear sets with clutches and brakes for speed selection. The planet carriers of the sets are connected together and positively connected to the output shaft, while the planet gearing for the first two gear sets utilizes a planet gear of the second gear set which extends axially over both the first and second gear sets and meshes with the internal and sun gears of the second gear set, and a planet gear on the common planet carrier which meshes only with the internal gear of the first gear set and with the planet gear of the second gear set.

    摘要: Where different 3-phase systems are connected to each other via two static converters having an intermediate direct-current circuit, the exchange of power via the intermediate direct-current circuit can be interrupted by a severe disturbance, for example by failure of a static-converter or by line or busbar faults causing a short-circuiting of one of the static converters. This interruption means a change in the balance of effective power and, associated with this, a shedding of reactive load for the other undisturbed 3-phase system. To reduce high dynamic overvoltages which can lead to plant components being endangered or to operational disturbances, the firing angle of the static converter remaining in operation is regulated with dependence on the alternating voltage of the alternating-current system connected to this static converter, in such a manner that the overvoltage is reduced. This is carried out by regulating the current. The firing angle can be adjusted simultaneously with the short circuiting of the intermediate direct-current circuit by means of a short circuit device.
