OIL LEAK PREVENTION STRUCTURE FOR OIL FAN OF AUTOMATIC TRANSMISSION

摘要

In the present invention, the case 24 while maintaining a certain distance from the lower outer circumference with respect to the case 12 of the transmission 10 in which the extension portion 24 formed on the outer circumference of the oil pan 20 is bolted to the oil pan 20 is maintained. When the sealant 30 is applied to the surfaces of the case 12 and the oil pan 20, the sealant 30 is surrounded by a lower outer circumference of the case 12 because the structure is formed to protrude vertically upward from the bottom height of 12). Since the application area can be increased to be fixed between the side corner portion and the oil pan 20, the sealant applied to the joint surface 22 in contact with the case 12 and the oil pan 20 in a harsh external environment Even if the 30 is hardened and a gap is generated, it is possible to prevent the oil leak from being generated by the sealant 30 fixed to the extension part 24, as well as to increase the number of bolts due to the increase in the area of the sealant 30. Since it can be designed to reduce, there is an advantage of reducing the weight of the transmission 10 as well as cost reduction.
