Clutchless compressor

Abstract

Disclosed is a clutchless compressor which is structured to interrupt power transmission from a vehicle engine to a compressor which is actuated by the engine at occurrence of overload torque. The clutchless compressor comprises: a pulley actuated by an engine; a connector member tightly fixed to an inner periphery of the pulley, and having a number of break portions defined by slots formed along the circumferential direction thereof; and a disk plate mounted on the connector member to be coupled with the connector member while being connected with a rotational shaft of the compressor. The pulley is coupled with the disk plate via the connector member which is tightly fixed to the pulley, and the break portions in the connecting member are broken in order to reduce the number of components necessary for coupling and breaking thereby to save manufacturing cost and facilitate assembly.

1 . A clutchless compressor comprising: 
 a pulley actuated by an engine;    a connector member fixed to an inner periphery of the pulley and having a number of break portions formed along the circumferential direction thereof; and    a disk plate mounted on the connector member to be coupled with the connector member while being connected with a rotational shaft of the compressor.    
   
   
       2 . The clutchless compressor according to  claim 1 , wherein the connector member includes: an insert portion fit into the inner periphery of the pulley and a coupling portion coupled with the disk plate and wherein the break portions connect the insert portion with the coupling portion.  
   
   
       3 . The clutchless compressor according to  claim 1 , wherein the coupling portion has a number of projections projected radially from peripheral portions thereof, and the disk plate has coupling recesses formed in a face opposite to the pulley to correspond the projections, whereby the projections are inserted into the coupling recesses to connect the disk plate with the connector member.  
   
   
       4 . The clutchless compressor according to  claim 3 , wherein a number of dampers are interposed between the projections and the coupling recesses.  
   
   
       5 . The clutchless compressor according to  claim 1 , wherein the connector member includes: an insert portion fit into an inner periphery of the pulley; a flange connected with the insert portion and seated on a front portion of the pulley; and a coupling portion coupled with the disk plate, and wherein the break portions connect the flange with the coupling portion.  
   
   
       6 . The clutchless compressor according to  claim 5 , wherein a number of connecting slots are formed along the circumferential direction on a face of a coupling portion opposite to the disk plate, and wherein the disk plate has connecting projections formed in a face thereof opposite to the pulley to correspond to the connecting slots.  
   
   
       7 . The clutchless compressor according to  claim 6 , wherein a number of dampers are interposed between the connecting slots and the connecting projections.
