Abstract

PURPOSE:To enable the installation and removal of a device and the maintenance effected by arranging a limited slip differential device at the outside of a differential gear support bearing on a differential sidegear shaft and between a differential final gear and a differential sidegear shaft. CONSTITUTION:In a transmission case M which is composed of a right case 1 and a left case 2, the left case 2 is allowed to be a rear axle housing simultaneously so as to enable a limited slip differential device A to be contained inside, and the right case 1 is allowed to contain a differential gear device D at its center. The rotation of a shaft 20, to which a rotational power is transmitted through a HST transmission, allows a front wheel drive power transmitting shaft 21 to rotate through a gear train, and simultaneously allows a differential final gear 5 to rotate through a differential gear device D. A differential gear device A is arranged on a differential sidegear shaft 8L which is located outside a bearing 42 that is fitted in outside to support a gear 5. This configuration allows the differential final gear 5 and the gear device D to remain as they are even if the device a is removed.

However, the conventional solitude is a limited slip differential
Since all T1L transmissions were reassigned to the central part of the transmission case, the maintenance was reduced to six in one go, and there were two models with a limited slip differential head and one without a limited slip differential device. This happened very rarely during my first pregnancy.
