Technical Field

The utility model relates to the technical field of motors, in particular to a cycloid hydraulic motor with a hydraulic control hydraulic clutch device.

Background

The hydraulic pump and the hydraulic motor in the hydraulic transmission both work by the volume change of the working chamber, so the hydraulic pump can be used as the hydraulic motor, and the hydraulic motor can also be used as the hydraulic pump.

according to the utility model, the clutch plate is arranged, the high-pressure containing cavity and the low-pressure containing cavity are connected with each other through the through hole of the clutch plate, and the movable piston capable of sealing the through hole of the clutch plate is arranged, so that the rotating speed of the motor can be regulated and controlled according to requirements, the application range of the motor is improved, and the clutch plate has practicability.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

The device comprises a stator pair 1, a clutch plate 2, a movable piston 3, a rear end cover 4, a through hole 5 and a sealed cavity 6.

Detailed Description

The present invention is further illustrated by the following detailed description, which is to be construed as merely illustrative and not limitative of the remainder of the disclosure, and modifications and variations such as those ordinarily skilled in the art are intended to be included within the scope of the present invention as defined in the appended claims.

As shown in fig. 1, a cycloid hydraulic motor with a hydraulic control hydraulic clutch device comprises a housing, wherein a rotating stator pair 1, a clutch plate 2 and a rear end cover 4 are arranged in the housing, the rear end cover 4 is provided with an oil port communicated with a sealed cavity 6, the oil port is arranged in the circle center of the rear end cover 4, the clutch plate 2 is arranged between the rotating stator pair 1 and the rear end cover 4, the rotating stator pair 1 forms a low-pressure cavity and a low-pressure cavity in the housing, the clutch plate 2 is provided with through holes 5 communicated with the high-pressure cavity and the low-pressure cavity, the through holes 5 are uniformly distributed along the circumferential direction of the clutch plate 2, the through holes 5 are oval, the sealed cavity 6 is formed between the clutch plate 2 and the rear end cover 4, a movable piston 3 capable of sealing the through holes 5 is arranged in the sealed cavity 6, and the movable piston 3 can move back and forth in the sealed cavity 6.

The specific working process and principle of the utility model are as follows: when a conventional output function is adopted, pressure oil is supplied from an oil port of the rear end cover 4, the movable piston 3 is driven to move through the pressure oil, so that the movable piston 3 is tightly attached to the clutch plate 2, and the through hole 5 of the clutch plate 2 is sealed, at the moment, the through hole 5 is used for communicating the high-pressure cavity and the low-pressure cavity, the high-pressure cavity and the low-pressure cavity are not communicated after the through hole 5 is sealed, and the motor works normally; when pressure oil is removed from the oil port of the rear end cover 4, pressure generated by rotation of the rotating stator pair 1 can enable the movable piston 3 to be separated from the clutch plate 2, so that the high-pressure cavity and the low-pressure cavity are opened, oil can freely circulate between the rotating stator pair 1 and the rear end cover 4, and the super-high-speed motor driven state is achieved.
