Title:
PROTECTIVE STRUCTURE OF POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2018062205
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent oil leakage of a power transmission device caused by an impact load occurring at the time of road surface interference of a vehicle.SOLUTION: A casing 31 accommodates a gear mechanism of a power transmission device 3 therein. A gear chamber G which reserves lubrication oil for lubricating the gear mechanism is demarcated over a first coupling part cb1 which couples case members. The ground clearance of the first coupling part cb1 is set to be lowest on the bottom parts of the casing 31 and a cylinder block 21 of an engine. An under cover 4 has a projection 41, which projects upward, in its predetermined part separating from immediately below of the first coupling part cb1 in the bottom part. A space s2 between the projection 41 of the under cover 4 and the bottom part is set to be smaller than a space s1 between the under cover 4 and the first coupling part cb1.SELECTED DRAWING: Figure 1
