Abstract

PURPOSE:To set headway not only to second gear speed at the forward side but also second gear at the backward side by disengaging each of four clutches and vice versa so properly. CONSTITUTION:At forward first gear speed, power out of an input shaft 2 is transmitted to an output gear 6 from a forward first gearing pinion 16 via a forward first gearing input gear 19 and a forward first gearing clutch 18 from an input gear 20 on a shaft 2. At forward second gear speed, it is transmitted to a gear 6 from the gear 20 via a forward second gearing input gear 25, a forward second gearing clutch 24 and a forward second gearing pinion 22. At backward first gear speed, the power is transmitted to a backward first gearing pinion 8 from the shaft 2 via a backward first gearing clutch 10 and then it is transmitted to the gear 6 directly. At backward second gear speed, the power is transmitted to a backward second gearing pinion 9 via a backward second gearing pinion 11 and furthermore it is transmitted to the forward second gearing pinion 22 from the gear 9 via an intermediate driven gear 27 and an intermediate driving gear 28, then it is transmitted to the output gear 6 via this gear 22. Therefore headway is alterable according to various operations at the backward side.
