Document Type and Number:
Japanese Patent JP6669835
Kind Code:
B2
Abstract:
To provide a transmission whose driving force is uninterrupted, whose shift shock or acceleration delay is suppressed, and which can reduce weight and simplify a structure.SOLUTION: A transmission 1 includes: a plurality of stages of shift gears 29 supported by a driving force transmission shaft; clutch rings 63 which are arranged on both sides respectively with shift gears at two or more speed levels apart and can selectively engage with shift gears on both sides; and a shift operation part selectively operating the clutch rings 63. In the transmission which causes an axial force in a disengagement direction of the clutch rings 63 at a shift lower stage and the shift upper stage when the clutch rings 63 at the shift lower stage and the shift upper stage are simultaneously engaged by operation of the shift operation part, the clutch rings 63 and a shift gear 29 are provided with clutch teeth 51b, 29a engaged in the rotation direction. The clutch teeth 51b, 29a are provided with a guide surface 51ba generating a thrust force in the disengagement direction by operation of an inclined plane with coasting torque.SELECTED DRAWING: Figure 1
