Abstract
There is provided an oil separating structure of an automatic transmission, which makes it difficult for an oil strainer of an oil pump to draw oil containing air bubbles. A baffle plate base separates a space around the oil strainer and a space around a driven sprocket as well as a final gear, and therefore, oil containing air bubbles formed as a result of agitation by the driven sprocket, chain, and final gear does not flow directly into the oil strainer. As a result, the oil strainer is unlikely to draw oil containing air bubbles.
Claims9
An oil separating structure of an automatic transmission, comprising a first baffle plate comprising:
- a chain cover section disposed between a driven sprocket of an oil pump, at least part of which is disposed within oil, and an oil strainer, for separating a space around the driven sprocket and a space around the oil strainer;
- and
- a final gear cover section connected to said chain cover section and disposed between a final gear at least part of which is disposed within oil and the oil strainer, for separating a space around the final gear and the space around the oil strainer.
An oil separating structure of an automatic transmission, comprising:
- a first baffle plate disposed between a driven sprocket of an oil pump, at least part of which is disposed within oil, and an oil strainer, for separating a space around the driven sprocket and a space around the oil strainer;
- a second baffle plate disposed on opposite side of said first baffle plate with respect to the driven sprocket, for separating a space around the driven sprocket and a space around a transmission case located on opposite side of said first baffle plate with respect to the driven sprocket;
- and
- an elastic member provided at a junction of said first baffle plate and said second baffle plate,
- wherein said first baffle plate, said second baffle plate, and said elastic member enclose at least an oil-immersed path of a chain extended over the driven sprocket.
