Description

Technical Field

[0001] This utility model relates to the field of automotive cooling water pump technology, specifically to an electromagnetic dual-speed water pump clutch. Background Technology

[0002] The automotive water pump is a core component of the engine cooling system, responsible for driving the coolant circulation to regulate engine temperature and prevent overheating damage. Its working principle involves the engine pulley driving an impeller to rotate, using centrifugal force to circulate the coolant between the engine and the radiator. In modern cars, electronic water pumps can also precisely control the flow rate via the vehicle's computer, improving energy efficiency.

[0003] The water pump clutch is a crucial component of an automotive water pump. Existing water pump clutches operate at a constant speed, resulting in a constant flow of coolant. When the vehicle's output power increases or decreases, this can easily lead to insufficient or excessive coolant usage, hindering cooling. To address these technical issues, we have designed an electromagnetic dual-speed water pump clutch. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an electromagnetic dual-speed water pump clutch.

[0005] The purpose of this utility model can be achieved through the following technical solution: an electromagnetic dual-speed water pump clutch, including a pulley and a housing, wherein magnetic cups are embedded at the top and bottom of the inner wall of the pulley, a mounting seat is movably installed on the left side of the pulley, a retaining spring is installed on the right side of the inner wall of the housing, a bearing is installed at the center of the inner wall of the mounting seat, a spring is provided on the left side of the housing, and a clutch disc is provided on the left side of the spring.

[0006] This electromagnetic dual-speed water pump clutch, through the cooperation of a pulley, magnetic cups, spring plates, and a clutch disc, has the advantage of freely switching between high and low speeds. When the pulley needs to rotate at low speed, an external control signal controls one of the two magnetic cups to operate. The magnetic cup generates magnetism to attract the clutch disc, overcoming the elasticity of the spring plates, causing the clutch disc to move towards the pulley, making the pulley rotate at low speed along with the clutch disc. When the pulley needs to rotate at high speed, an external control signal controls all the magnetic cups to operate. The magnetic cups generate magnetism to attract the clutch disc, overcoming the elasticity of the spring plates, making the clutch disc move towards the pulley, making the pulley rotate at high speed along with the clutch disc, thus improving the pumping capacity of the water pump and enhancing the cooling effect.

[0007] In the aforementioned electromagnetic dual-speed water pump clutch, a retaining groove is provided on the right side of the inner wall of the housing for use with a retaining spring. This groove facilitates the installation of the retaining spring.

[0008] In the aforementioned electromagnetic dual-speed water pump clutch, the left side of the clutch disc is provided with several internally grooved short cylindrical head screws and rivets, and the right side of the internally grooved short cylindrical head screws and rivets all penetrate the clutch disc and the spring plate and extend into the interior of the housing. The internally grooved short cylindrical head screws and rivets facilitate the installation of the clutch disc and the spring plate.

[0009] In the aforementioned electromagnetic dual-speed water pump clutch, the left side of the housing is provided with mounting holes one and two for use with internal perforated groove short cylindrical head screws and rivets. The use of mounting holes one and two facilitates the installation of the internal perforated groove short cylindrical head screws and rivets.

[0010] In the aforementioned electromagnetic dual-speed water pump clutch, the housing is located on the right side of the pulley, and an enameled wire is connected to the left side of the mounting base. The housing facilitates bearing installation.

[0011] Compared with existing technologies, this electromagnetic dual-speed water pump clutch, through the cooperation of a pulley, magnetic cups, spring plates, and a clutch disc, has the advantage of freely switching between high and low speeds. When the pulley needs to rotate at low speed, an external control signal controls one of the two magnetic cups to operate. The magnetic cup generates magnetism to attract the clutch disc, overcoming the elasticity of the spring plates, causing the clutch disc to move towards the pulley, making the pulley rotate at low speed along with the clutch disc. When the pulley needs to rotate at high speed, an external control signal controls all the magnetic cups to operate. The magnetic cups generate magnetism to attract the clutch disc, overcoming the elasticity of the spring plates, causing the clutch disc to move towards the pulley, making the pulley rotate at high speed along with the clutch disc, thus improving the pumping capacity of the water pump and enhancing the cooling effect.
