Abstract

The invention discloses a clutch used for a variable displacement rotary swash plate compressor of a vehicle air conditioner. The clutch comprises a belt wheel assembly (1) and a driven wheel assembly (2), wherein the axial central hole of a belt wheel (11) is matched with a bearing (12); the belt wheel (11) is provided with a plurality of connecting holes (13); the driven wheel (2) comprises a drive plate (21) which comprises an inner ring (211) with an inward extending part and an outer ring (212) with an outward expanding part; the inward extending ring of the inner ring is provided with a plurality of discontinuous grooves (214); neighboring grooves form a connecting rib (215); the outward expanding part of the outer ring is provided with a plurality of connecting holes (216); the outer ring is connected with a locking screw (3) through the belt wheel; a coupling body (4) and the inward extending part thereof are connected coaxially by using a radial outward expanding part (41) thereof; and the connecting point between the coupling body and the inner ring is closer to the axial centre of the drive plate than the plurality of grooves on the inner ring. The clutch has the characteristics of simple structure, reduced machining process, reduced machining cost and uniform stress; and an overload protection effect is ensured.

Description

technical field [0001] The invention relates to a variable-displacement rotary swash plate compressor for an automobile air conditioner, in particular to a clutch used for the compressor. Background technique [0002] The clutch of the variable-displacement swash-plate compressor of the automobile air-conditioning refrigeration unit is used to transmit the power from the automobile engine to the variable-displacement swash-plate compressor. see figure 1 , the figure shows the perspective exploded view of the existing clutch, which includes a drive plate assembly 20, a plastic driven plate 21 for overload protection, a rivet 22, a pulley 23, a bearing 24 and a screw 25. Such as figure 2 As shown, the cross-sectional view of the clutch is shown in the figure, from which it can be seen that the longitudinal axis of the inner hole of the bearing 24 is coaxial with the longitudinal axis of the pulley 23 and the longitudinal axis of the drive disc 20 . The outer diameter of th...
