Embodiment Construction

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like figure 1 As shown, the present invention provides a constant torque driver for an automobile air conditioner, which includes a pulley 1 and a spline 6, and a set of three reeds 5, bolts 2, sleeves 8, cotter pins A3, and cotter pins B4 that are matched and connected. , rivet 7, preload plate 9 (see Figure 5 )as well as. When the engine rotates, the belt drives the pulley 1 to rotate. When the pulley 1 rotates, it also drives the reed 5 to rotate, thereby pushing the spline 6 to rotate, thereby driving the compressor shaft to rotate, and finally driving the entire compressor system to work.

[0028] like figure 1 , Figure 5 As shown, one end of the reed 5 is provided with a section of pre-tensioning plate 9 , and the reed 5 and the pre-tensioning plate 9 are directly fixed on the spline 6 by rivets 7 . The other end of ...

Abstract

The invention relates to an automobile air-conditioner fixed torque driver which comprises a belt wheel (1) and a spline disc (6). A set of leaf springs (5) are arranged. One end of each leaf spring is connected to one end face of the belt wheel through a bolt (2), and the other end of each leaf spring is connected to the spline disc through a rivet (7). The opposite edges of each leaf spring are provided with opposite split pin holes respectively. Outer side positioning pins (3) and inner side positioning pins (4) correspondingly matched with the split pin holes are arranged on the spline disc. The automobile air-conditioner fixed torque driver has the advantages that the portion between the two split positioning pin holes in the leaf springs is the stress concentration position; when a compressor is overloaded continuously, the stress concentration position is most likely to be snapped, the compressor overload protection effect is achieved, and the rated torque of the automobile air-conditioner fixed torque driver can be determined by determining a tension value during snapping. When the compressor is overloaded instantaneously, the inner and outer side positioning pins are extruded and retracted, large instant elasticity is fed back to the leaf spring, and it has been ensured that the leaf springs can continue to be in use normally after being overloaded instantaneously.

Description

technical field [0001] The invention relates to a constant torque driver for an automobile air conditioner, which belongs to the technical field of mechatronics, and is mainly suitable for an automobile air conditioner compressor system. Background technique [0002] For intelligent air conditioners, how to effectively protect the operation of the engine gear train and ensure the normal operation of the car when the air conditioner system fails has become one of the important research topics for most automobile companies. The solution is given in the drive. [0003] The existing fixed torque driver structure is mainly a vulcanized rubber spring on the flower keyboard, the outer circle of the rubber spring is connected to the outer ring, the outer ring is fixed on the end face of the pulley by screws, and the torque is transmitted by the deformation of the rubber spring. Twist off to protect the compressor. [0004] CN201010617112 discloses a belt pulley of an automobile ai...
