Abstract
The utility model discloses an electromagnetic clutch for an automobile air conditioner. The electromagnetic clutch comprises a belt pulley, a bearing and a driving disc assembly; the driving disc assembly comprises a rubber connecting piece and a driving disc; a connecting projection is arranged on the rubber connecting piece; a torque restriction arm is arranged on the driving disc; a connecting hole is arranged in the belt pulley; the rubber connecting piece is fixed on the driving disc; the bearing is fixed in the belt pulley; the driving disc assembly is inset in the belt pulley; and the connecting projection on the rubber connecting piece passes through the connecting hole in the belt pulley. According to the utility model, by adopting the casting technology, the driving disc is connected with the rubber connecting piece, and on the basis that the connection strength and reliability are ensured, cost is reduced, fasteners are reduced, and production efficiency is enhanced; common aluminum materials are replaced by cast iron materials, so stability of the product quality is ensured; and the torque restriction arm is additionally arranged on the driving disc, so when breakdown leads to overlarge torque, the torque restriction arm is twisted off, so economical losses probably caused by accidents are effectively reduced.
Description
Technical field
The present invention relates to a kind of clutch, relate in particular to a kind of used for automobile air conditioning magnetic clutch.
Background technique
Automobile air conditioner electromagnetic clutch is a power transmitting deice between motor car engine and automobile air conditioner compressor; Be different from family expenses or business air conditioner, receive the restriction of vehicle structure, automobile air conditioner compressor is driven by magnetic clutch by motor car engine.Therefore, for car air conditioner, clutch one of the assembly that is absolutely necessary.
Existing clutch generally adopts split-type structural design, and number of spare parts is many, complex structure, therefore has cost of production high, the shortcomings such as production process complexity.Meanwhile, existing air conditioning clutch all adopts aluminium material manufacture, and aluminium material unstable properties causes the fluctuation of clutch quality of product large, and up-to-standard rate is low.Present people thirst for a kind of used for automobile air conditioning magnetic clutch method and solve the problem in reality.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of used for automobile air conditioning magnetic clutch is provided.
Used for automobile air conditioning magnetic clutch comprises a belt pulley, bearing drive plate assembly, and drive plate assembly comprises rubber connector, drive plate, and rubber connector is provided with connection projection, and drive plate is provided with torque limit arm, and belt pulley is provided with attachment hole; Rubber connector is fixed on drive plate, and bearing is fixed in belt pulley, and drive plate assembly is embedded in belt pulley, and the connection projection on rubber connector is through the attachment hole on belt pulley.
A kind of drive plate of used for automobile air conditioning magnetic clutch is provided with 3～5 torque limit arms.
The drive plate material of used for automobile air conditioning magnetic clutch is a cast iron, and rubber connector material is nitrile butadiene rubber, and drive plate is connected with the mode of rubber connector by casting.
The present invention, by adopting casting technique, is connected drive plate with rubber connector, guaranteeing, on the basis of join strength and reliability, to have reduced cost, reduced the use of fastening piece, has promoted manufacturing efficiency; The aluminium material generally adopting is replaced with to cast iron materials, guaranteed the stability of quality of product; By set up torque limit arm on drive plate, while causing torque excessive when breaking down, torque limit arm twists off, the economic loss that the accident of effectively reducing may cause.
