4-wheel driving car

Abstract

Abstract PURPOSE:To apply a proper driving force onto wheels even under the traveling conditions having a small friction coefficient by controlling the switching between 2-wheel drive and 4-wheel drive of a switching mechanism and the diff- lock operation of a differential-gear restricting mechanism in relation. CONSTITUTION:A 4-wheel driving transfer 40 transmits a power from the first output shaft 42 to a rear-wheel driving shaft C by switching-operating a clutch and a brake which are built-in and transmits a power from the second output shaft 52 to a front-wheel driving shaft B, and 2-wheel driving and 4-wheel driving are selectively switched. The first output shaft 42 is connected to the right and left axles 601b and 602b through a differential mechanism 70 equipped with a differential-gear restricting mechanism built-in. In this case, when a slip is generated between the right and left wheels 601a and 602a, the differential-gear restricting mechanism is operated, and when a slip is generated afterwards, switching from 2-wheel driving state to 4-wheel driving state is performed.
