Hybrid compressor

Abstract

A hybrid compressor may include a pulley, a drive shaft protruding from a housing while passing through the pulley and selectively connected to the pulley to thereby be rotated, a rotation plate connected to a second end portion of the drive shaft and rotatably disposed in the housing, a swash plate hinge-coupled to the rotation plate and rotated together with the rotation plate, at least one piston reciprocating to be selectively inserted into a compression chamber provided in the housing in the case in which the swash plate is rotated, a motor unit selectively transferring a torque generated depending on whether or not power is applied thereto to the drive shaft and mounted at a side end of the housing to correspond to a first end portion of the drive shaft, and a torque transfer unit selectively connecting the pulley or the motor unit to the drive shaft.

What is claimed is: 
     
         1 . A hybrid compressor comprising:
 a pulley rotatably mounted at a side of a housing;   a drive shaft having a first end portion protruding from the housing while passing through the pulley and a second end portion inserted into the housing, and selectively connected to the pulley to thereby be rotated;   a rotation plate having a rotation center connected to the second end portion of the drive shaft and rotatably disposed in the housing;   a swash plate hinge-coupled to a side of the rotation plate and rotated together with the rotation plate;   at least one piston connected to an outer peripheral edge of the swash plate and reciprocating to be selectively inserted into a compression chamber provided in the housing in a case in which the swash plate is rotated;   a motor unit selectively transferring a torque generated depending on whether or not power is applied thereto to the drive shaft and mounted at a side end of the housing to correspond to the first end portion of the drive shaft; and   a torque transfer unit installed at a first end of the drive shaft between the pulley and the motor unit and selectively connecting the pulley or the motor unit to the drive shaft.   
     
     
         2 . The hybrid compressor of  claim 1 , wherein the motor unit includes:
 a motor housing mounted at a side end of the housing in a state in which a first end thereof encloses the pulley;   a motor shaft rotatably provided in the motor housing at an opposite side to the pulley;   a friction plate mounted at the first end of the motor shaft corresponding to the pulley to thereby be rotated together with the motor shaft;   a rotor provided at a second end portion of the motor shaft; and   a stator disposed on an inner peripheral surface of the motor housing to correspond to the rotor.   
     
     
         3 . The hybrid compressor of  claim 2 , wherein the motor shaft is disposed on a coaxial line with the driver shaft and has a mounting groove formed in a front end thereof, the mounting groove having the first end portion of the drive shaft partially inserted thereinto. 
     
     
         4 . The hybrid compressor of  claim 3 , wherein the drive shaft is mounted in the mounting groove through a bearing. 
     
     
         5 . The hybrid compressor of  claim 4 , wherein the bearing is a one-way bearing. 
     
     
         6 . The hybrid compressor of  claim 2 , wherein the torque transfer unit includes:
 a clutch plate having a rotation center mounted at a first end of the drive shaft; and   a clutch member mounted on an outer peripheral surface of the clutch plate and mounted to be reciprocatable toward the pulley or the friction plate on the outer peripheral surface of the clutch plate based on an axial direction of the drive shaft.   
     
     
         7 . The hybrid compressor of  claim 6 , wherein the clutch member is formed of an electromagnet generating electromagnetic force depending on whether or not power is applied thereto. 
     
     
         8 . The hybrid compressor of  claim 6 , wherein the pulley has a magnetic force member mounted therein to correspond to the clutch member. 
     
     
         9 . The hybrid compressor of  claim 8 , wherein the magnetic force member generates electromagnetic force depending on whether or not power is applied thereto, thereby connecting the clutch member to the pulley. 
     
     
         10 . The hybrid compressor of  claim 1 , wherein the pulley is connected to an engine through a connection belt and is rotatably mounted at a first end of the housing through a bearing.
