Title:
SPEED CHANGE GEAR
Document Type and Number:
Japanese Patent JP2015064043
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a speed change gear capable of performing multi-stage transmission and improving extensibility.SOLUTION: A speed change transmission 1 comprises: a housing H; four planetary mechanisms P1-P4; four clutches C1-C4; two brakes B1, B2; plural coupling members for coupling elements of the respective planetary mechanisms P1-P4; an input shaft N; and an output shaft T. A first coupling member 62 on which a third clutch C3 is arranged on an outer peripheral side than a second coupling member 61 for coupling a ring gear P2r of the second planetary mechanism P2 and a carrier P3c of the third planetary mechanism P3. An installation face 62b1 on which a third brake B2 opposed to an inner periphery Ha of the housing H and braking rotation of a coupling portion 62b can be additionally provided is formed at the coupling portion 62b of the first coupling member 62 for coupling a ring gear P3r of the third planetary mechanism P3 and the third clutch C3.
