ZF ya ha recibido pedidos por valor de miles de millones de BMW y Fiat Chrysler para la nueva transmisi\u00f3n autom\u00e1tica de m\u00f3dulo h\u00edbrido de ocho velocidades. El proveedor proporciona ahora m\u00e1s detalles sobre la transmisi\u00f3n.<\/p>\n
Un sistema modular permite implementar transmisiones h\u00edbridas suaves, completas y enchufables con potencias m\u00e1ximas de 24 a 160 kW. La electr\u00f3nica de potencia ya no se dise\u00f1a como una unidad independiente, sino que est\u00e1 totalmente integrada en la carcasa de la transmisi\u00f3n.<\/p>\n
Esto es posible porque ZF dise\u00f1\u00f3 la transmisi\u00f3n para la hibridaci\u00f3n desde el principio. Hasta ahora, el convertidor de par de las transmisiones h\u00edbridas (tambi\u00e9n de ZF) se sustitu\u00eda simplemente por un motor el\u00e9ctrico con la mayor densidad de potencia posible. Dado que la carcasa de la transmisi\u00f3n, dise\u00f1ada originalmente para un convertidor, especificaba el dise\u00f1o, las transmisiones autom\u00e1ticas anteriores estaban muy limitadas en su rendimiento el\u00e9ctrico.<\/p>\n
ZF afirma haber \"dado la vuelta a la tortilla\" con la nueva transmisi\u00f3n, ya que la carcasa se ha dise\u00f1ado para un motor el\u00e9ctrico m\u00e1s grande y potente. Sin embargo, las dimensiones exteriores de la transmisi\u00f3n no aumentan: Con un nuevo sistema de control hidr\u00e1ulico significativamente m\u00e1s peque\u00f1o, ZF afirma haber conseguido encontrar el espacio de instalaci\u00f3n necesario para los componentes el\u00e9ctricos y electr\u00f3nicos.<\/p>","protected":false},"excerpt":{"rendered":"

Power electronics, which is now integrated into the transmission itself, also helps here. According to ZF, however, a new cooling system was necessary here because some of the power semiconductors can become very hot during operation. For car manufacturers, the integrated power electronics offer two advantages: On the one hand, they have to lay fewer high-voltage cables in the car, which increases safety. In addition, the power electronics, which previously had the size of a shoe box, no longer have to be installed in the car – according to the manufacturer, the assembly of the new hybrid transmission is no longer much more complex than that of a conventional transmission.<\/p>\n
With the new electric motor (in addition to the mentioned peak power of 160 kW, ZF specifies a continuous output of 80 kW), the electric driving components of the PHEV are to be significantly increased. Even without the combustion engine, the maximum torque is 450 Newton meters – this should allow rapid acceleration even in pure E mode, for example during overtaking manoeuvres.<\/p>\n
The transmission is not only designed for PHEVs, but also for mild hybrids with 48 V operating voltage. Here the electric motors are not located in the gearbox itself, but mostly on the crankshaft at the engine output (called P1) or as P2 on the gearbox input shaft.<\/p>\n
ZF will start production of the fourth generation of the eight-speed automatic transmission in 2022, initially in Saarbr\u00fccken, Germany; shortly thereafter, the market launch in China and the USA will also take place. ZF has already found the first customers for the transmission: Only at the beginning of the month, the third-largest German supplier announced that Fiat Chrysler<\/a> had placed a major order for automatic transmissions with hybrid components with ZF after BMW. Together with the order from BMW<\/a>, the order volume adds up to 15 to 20 billion euros – ZF did not mention exact figures here.<\/p>\n
