Drive device with the motor rocker arm and the use of a motor rocker

摘要

Drive device with the motor rocker (6) and electric motor (1),the driving device is a of the electric motor (1) has a transmission which can be driven with lubricant, at least partially filled,the motor rocker (6) as a hollow space of a hollow part is embodied and, at least partially filled with lubricant,the motor rocker (6) in the form of cooling ribs or cooling fingers projecting sections acting,the drive device has an air guide means, which is a of a fan of the drive device to the cooling air flow produced on the motor rocker (6) shaped cooling fins, then the air flow in at least partially in their extension direction of the forwarding,where the electric motor (1) a liquid-cooled electric motor (1) is used, the through the engine (1) of the cooling liquid is guided into the cavity of the motor rocker (6) is fed from - or,the cavity as one piece with the transmission cooling liquid cavity,a first pipe (9) from the transmission interior space and the cavity of the motor rocker (6) leads, with transmission interior space and the hollow space at least partially filled with lubricant are,a second conduit (7, 8) from the hollow space of the motor rocker (6) via a pump device to the transmission interior space leads,the cavity is divided into several chambers, so that the of the first pipe (9) lubricant flowing in the chambers pass through in succession and the second conduit (7, 8) opens into the last of the chambers,the chambers with the defoaming of the lubricant beförder material foam lateral openings are connected, whereby one of the openings in the lower part is free and in the upper partial region of the opening is provided with a grating.
