Automobile air conditioner torque transmission device

Abstract

The invention provides an automobile air conditioner torque transmission device. The automobile air conditioner torque transmission device comprises a spline disc (1), wherein the spline disc (1) is provided with a compressor main shaft (2) in a penetrating mode; and one side of the spline disc (1) is provided with a belt wheel (3) coaxial to the compressor main shaft (2). The automobile air conditioner torque transmission device is characterized in that a cover shell (4) is arranged on the other side of the spline disc (1), a flange (4a) which is connected with the belt wheel (3) in a matchedmode is arranged at one end of the cover shell (4), a friction plate (4b) matched with the spline disc (1) is arranged on the inner wall of the cover shell (4), and a bolt (5) is arranged on the cover shell (4) in a penetrating mode; the lower end of the bolt (5) is connected with the compressor main shaft (2) in a matched mode; and a gasket (6) is arranged between the nut of the bolt (5) and thecover shell (6). The automobile air conditioner torque transmission device is simple in structure and low in manufacturing cost; and when the torsion exceeds a control value, the friction plate starts to slip, and then over-torque protection of a compressor is achieved.

Description

Technical field: [0001] The invention relates to an automobile component, in particular to an automobile air conditioner torque transmission device. Background technique: [0002] Existing automotive air-conditioning torque transmission devices have a torque limiting function and when the rotational speed of the pulley is too large, when the torque transmitted to the dial exceeds a certain limit, the torque limiting function will be triggered so as to protect the air-conditioning compressor from Damaged by overload. [0003] However, most of the structures of the torque limiters in the existing automobile air-conditioning torque transmission devices are relatively complicated, which increases the manufacturing cost of the air-conditioning drive, and the maintenance after the protection device is damaged is also relatively inconvenient. Although there are some drivers with overload protection in the existing technology, most of them realize the over-torque protection by disc...

Problems solved by technology

[0003] However, most of the structures of the torque limiters in the existing automobile air-conditioning torque transmission devices are relatively complicated, which increases the manufacturing cost of the air-conditioning drive, and the maintenance after the protection device is damaged is also relatively inconvenient.

Although there are some drivers with overload protection in the existing technology, most of them realize the over-torque protection by disconnecting the reed in the driver, but the flying fragments often damage other parts when the reed is disconnected, and then the tiny The debris is also extremely difficult to remove completely, causing problems such as abnormal noise when the vehicle is running

Then, once the existing reed driver is disconnected and the over-torque protection is achieved, the device will fail, and a new car air-conditioning torque transmission device will be replaced.
