COMPONENT OPERATION / Travel Device TRAVEL MOTOR The travel motor is a swash plate type variable dis- placement axial plunger motor and equipped with parking brake (3) (with built in a wet-type negative multi-disc brake). The travel motor consists of swash plate (7), rotor (16), plunger (4) with the shoe, valve plate (1), output shaft (11), tilt piston (9) and casing (8). Four tilt pistons (9) shift the swash angle of swash plate (7) due to a fulcrum as ball (13). Rotor (16) sticks on valve plate (1) due to the spring (14) force.
