Abstract

PURPOSE:To optimize torque distribution to both wheels while providing a differential function by connecting a carrier rotary shaft to one side gear of a differential gear and a worm wheel rotary shaft to the other side gear, in the case of a differential limiter. CONSTITUTION:Constitution is provided with a worm gear 1, worm wheel 2 meshing with the worm gear 1 and a carrier 3 for holding the worm gear 1 to be made rotatable on the periphery of the worm wheel 2. When a difference is generated between rotational speeds of the carrier and the worm wheel, reaction force is generated between the carrier 3 and the worm wheel 2, and a differential limiting effect is automatically generated, by this reaction force, between both side gears 13, 14 connected to a differential gear 8 respectively. As a result, an ideal differential limiter, in which a wheel is prevented from slipping and racing and optimum torque distribution is made possible to both the wheels, is obtained.

いう欠点があった。Conventional differential limiting devices generally include viscous couplings that use oil viscosity and non-slip differentials that use cams. However, viscous couplings have the disadvantage that the oil viscosity, which should be constant, tends to change depending on temperature, and non-slip differentials transmit torque only to the low-speed wheels.
