Speed change mechanism for swash plate type hydraulic motor |
摘要 |
A two-stage speed change mechanism for a swash plate hydraulic motor, in which a swash plate is moved even during the revolution of the swash type hydraulic motor, thereby making it possible to vary the exclusion volume. An accommodating bore for accommodating a fixing pin is formed on a side wall of a housing. Piston for shifting the swash plate is provided, and control valves 14,15 and 16 each including a pilot line 14, a spool 15 and a compression spring 16 are installed for the actuation of the swash plate shifting piston 3. Thus the exclusion volume can be safely varied even during the rotating of the hydraulic motor.
