Abstract
A drive device for a motor vehicle. In particular a machine housing in which a lubricant consumer, a lubricant tank and a lubricant pump are arranged. The lubricant pump is fluidically connected on the suction side via a suction channel to the lubricant consumer and on the pressure side via a pressure channel to the lubricant tank and the lubricant tank is fluidically connected to the lubricant consumer via a flow channel. The suction channel, the pressure channel and the flow channel are each formed open with an opening in a base body of the machine housing and the openings are covered fluidically separate from one another by an end cover attached to the base body.
Claims19
A drive device for a motor vehicle comprising a machine housing comprising:
- a first lubricant consumer;
- a lubricant tank;
- and
- a first lubricant pump having a suction side and a pressure side, wherein the first lubricant pump is fluidically connected:
- on the suction side, via a first suction channel to the first lubricant consumer;
- on the pressure side, via both a pressure channel and a lubricant line to the lubricant tank, wherein the pressure channel is connected to a pressure chamber and the lubricant line enters the pressure chamber via a connection opening;
- and
- on the suction side, parallel to the first suction channel to a second suction channel and to a second lubricant consumer,
- the first suction channel, the pressure channel, and a flow channel are each formed open with an opening in a base body of the machine housing,
- the openings of the first suction channel, the pressure channel, and the flow channel are covered, fluidically separate from one another, by an end cover attached to the base body, the end cover having an opening formed therein,
- an inner surface of the opening of the end cover forming at least a portion of a wall of a suction nozzle configured to supply lubricant from an air space of the machine housing,
- the air space being delimited by a wall of the base body and by a machine housing cover fixed to the base body and being sealed off from an environment in a fluid-tight manner,
- the suction nozzle being fluidically connected to the second suction channel,
- the lubricant tank is fluidically connected via the flow channel and a second lubricant pump to the first lubricant consumer and separated from the air space by a partition wall,
- the lubricant tank is fluidically connected via the flow channel and a third lubricant pump to a second lubricant consumer, and
- a common drive is configured to drive the first lubricant pump, the second lubricant pump, and the third lubricant pump.
