Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
105 words
A banjo-shaped axle casing of the type including a differential housing and a pair of axle housings coupled to said differential housing comprising: at least one pair of mounting members provided on the inside surface and on each side of the axle casing and opposite each other; and at least one pair of flexible partitions inserted into the axle casing, said flexible partition being inserted into the axle casing such that they engage with the mounting members and partition the differential housing from the axle housing thereby preventing large amounts of oil from flowing into said axle housing during applications of a horizontal inertial force.
