Abstract: A transmission case is provided with a housing enclosing a clutch and/or torque converter connected to an engine, and a shifting mechanism case enclosing a shifting mechanism in an oil-tight state that is connected to the housing. A focus for stress resulting from an impact load acting on the transmission case is formed as a frangible portion in the housing. Thus, damage to the transmission from an excessive load is limited to the housing, and by absorbing the impact from that damage, damage to the shifting mechanism case is prevented and oil leakage from the transmission case is avoided.

Abstract translation: 变速器壳体设置有壳体，其包围连接到发动机的离合器和/或变矩器，以及换档机构壳体，其包围连接到壳体的油密封状态的换档机构。 由作用在变速器壳体上的冲击载荷产生的应力的焦点形成为壳体中的易碎部分。 因此，由于负载过大而对变速器的损坏被限制在壳体上，并且通过吸收来自该损坏的冲击，防止了变速机构壳体的损坏，并且避免了变速器壳体的漏油。
