Double drive planetary gear reducer and hydraulic clutch device

Abstract

The invention discloses a double drive planetary gear reducer and a hydraulic clutch device. The reducer and the device comprise a planetary reducer base and a middle gear, a connection flange and a clutch base. The middle gear, connection flange and the clutch base are sequentially arranged in the axial direction of the planetary reducer base. A clutch I and a clutch II are placed at two sides of the planetary reducer base. The axial directions of the clutch I and clutch II are in parallel with the axial direction of the planetary reducer base. The middle gear is connected with the planetary reducer base through a ball bearing, and is connected with the connection flange through a roller bearing. The double drive planetary gear reducer and the hydraulic clutch device achieve the coaxial disconnection and connection with reliable connection status, and are flexibly and agilely detachable. The switching between the clutch I and the clutch II is flexible and convenient. The structures of both the clutch I and clutch II are compact. The automatic selection between the single-input-driving-and-switching and double-input-driving-and-switching is achieved. The piston and the clutches are arranged on a fixed shell body. The oil line setting and control are convenient. The linkage control is easily achievable. The input shaft structure is simple. There is no necessity to arrange the bearing structures to sustain the axial direction force.

Description

technical field [0001] The invention relates to a hydraulic clutch device for a double-drive planetary reducer, which is suitable for the dual-input configuration of a hydraulic motor, is integrated at the input end of the planetary reducer, and can also be used in other occasions where transmission chains need to be disconnected and combined. For the matching market of reducers that require extremely high reliability and need to be equipped with a spare drive unit, or the matching market of reducers that bear a large load and have limited installation space, and require dual-input drives. Background technique [0002] In some applications where the reliability of the reducer is extremely high or the reducer bears a large load and the installation space is limited, the traditional planetary reducer cannot meet the requirements. The design of the double-input planetary reducer can meet this requirement. On the one hand, for the occasions where full load requires dual drives t...
