Problems solved by technology

[0002] The displacement of traditional hydraulic quantitative motors is a fixed value, and the displacement cannot be adjusted. Therefore, when the displacement demand is between the displacements of two adjacent quantitative motors, for example, when the actual displacement demand is less than A specification If the displacement of the motor is larger than that of the motor of the B specification, the displacement requirement cannot be met accurately; if a traditional variable motor or a fixed displacement motor with adjustable displacement is used, although it can meet different displacement requirements, its oblique The plate is a movable structure, so a special swash plate angle variable mechanism for adjusting the swash plate angle is required, and the cost is relatively high

Abstract

The present invention relates to a hydraulic motor with adjustable displacement and construction machinery equipped with the hydraulic motor. The hydraulic motor comprises: a motor casing; a main shaft arranged in the motor casing; a main shaft arranged in the motor casing and A plunger located radially outside the main shaft; a swash plate set in the motor housing and sheathed on the main shaft; wherein, the hydraulic motor can be detachably installed with rows of various inclination angles volume adjustment block so that the swash plate is connected between the inclined surface of the displacement adjustment block and the end of the plunger, displacement adjustment blocks at various inclination angles are installed into the hydraulic motor In the case of , the normal line of the swash plate forms different angles with the central axis of the main shaft.
