Embodiment
As shown in Figure 1, the utility model is used for the driver of Air conditioning compressor for displacement variable car, comprises drive plate assembly, belt pulley assembly, and the drive plate assembly is connected with compressor main shaft, and the belt pulley assembly is connected with the motor belt wheel by drivign belt; The drive plate assembly is connected fastening with the belt pulley assembly by screw 3;
As Fig. 2, shown in Figure 3, the drive plate assembly comprises drive plate 11, connecting shaft grip assembly 12, and connecting shaft grip assembly 12 is arranged at the center of drive plate 11, and connecting shaft grip assembly 12 and drive plate 11 are by a plurality of connecting pin 13 riveted fixing;
Connecting pin 13 can be three or more;
Connecting shaft grip assembly 12 is fixedlyed connected with compressor main shaft by spline.
Drive plate 11 comprises outer ring 111, interior ring 112, and outer ring 111 is connected to one with the rubber body 113 of interior ring 112 by annular;
The outer ring 111 of drive plate 11 is fastened on the end face of belt pulley 21 by a plurality of screws 3;
The end face 112A of interior ring 112 is higher than the end face 111A of outer ring 111; This structure can reduce the stile of outer ring 111 and the height of rubber body 113 outer ring parts, thereby saves raw material.
The cross section of rubber body 113 is a right-angled trapezium; Rubber body 113 has the effect of damping, buffering when transmitting torque, help the smooth transfer of load.
It is the drive plate rubber body 113 of right-angled trapezium that the utility model adopts the cross section, can make rubber body 113 have equal torque resistant intensity (strength of adhesive attachment that comprises rubber body and inside and outside ring limit) everywhere when bearing load.
As shown in Figure 3, the interior ring 112 of drive plate 11 is provided with a plurality of arc groove 112a that along the circumferential direction extend, and connects by connecting tendon 112b between per two arc groove 112a; Have angle between the bearing of trend of connecting tendon 112b and circumference tangential, as shown in Figure 4;
The number of arc groove 112a can be 3～6;
As shown in Figure 5, connecting tendon 112b is provided with v-depression 112c along its length direction.Work as overload of compressor, the moment of torsion value of overstepping the extreme limit, will rupture in the groove 112c place of connecting tendon 112b, thereby play the effect of overload protection.
Therefore the width of the shape of groove 112c, the degree of depth and connecting tendon 112b, the torque limit when thickness has determined overload protection jointly change shape and the parameter of connecting tendon 112b and groove 112c, just can adjust the limiting value of overload protection moment of torsion; And the position of groove 112c is the fracture position of connecting tendon 112b when overload.
