Modern automobiles have increasingly higher requirements for parts in terms of performance, cost, and ease of maintenance. The clutch, as one of the key components in the automotive transmission system, is widely used in the automotive industry and plays a vital role in controlling the power transmission between the engine and the transmission. It not only affects the performance of the vehicle during starting, acceleration, and deceleration, but is also directly related to the safety and comfort of the driving experience.

[0003] Electromagnetic clutch is widely used in air-conditioning compressors due to its advantages such as fast response speed and simple structure. Electromagnetic clutch usually includes a drive disc, a pulley and a coil assembly, wherein the pulley is installed on the compressor through a bearing, the pulley is connected to the car engine, the coil assembly is assembled on the compressor end cover on one side of the pulley, and a drive disc is provided on the other side of the pulley, the drive disc is connected to the main shaft of the air-conditioning compressor, and a reset mechanism for separating the drive disc and the pulley is installed on the other side of the drive disc. When the air conditioner is turned on, the current passes through the coil body to generate a magnetic field, which attracts the drive disc toward the pulley and fits it with the pulley. Due to the large friction between the drive disc and the end face of the pulley, the pulley drives the drive disc and the air-conditioning compressor to operate.

[0004] However, for commercial vehicles, the copper coil body of the automobile clutch has some obvious shortcomings: first, the copper material itself is expensive and heavy, which increases the cost and energy consumption of the entire vehicle; second, the copper coil body and the lead wire in the traditional design are an integrated structure, which makes the assembly process complicated and time-consuming, and also brings inconvenience to subsequent maintenance.

In at least one embodiment, the coil body 2 adopts an aluminum coil body 2, which can not only reduce the weight of the clutch, but also reduce the cost of the clutch and compressor production and assembly process. The core component 21 is made of ferrite material, which plays the role of transmitting magnetic flux to improve the efficiency and intensity of the magnetic field, thereby improving the efficiency of the coil body 2. When current passes through the coil body 2, a magnetic field will be generated in the core component 21, thereby driving the operation of the clutch. The connector 5 includes a first connector 51 and a second connector 52.
