PURPOSE: A water pump for a vehicle is provided to connect a capacitor and a magnet coil, to mount a plurality of the compressed coil springs each with a different coefficient of elasticity for a spring member, and to reduce noise which is generated when a clutch disk and a brake pad connect or separate. CONSTITUTION: A water pump for a vehicle(100) comprises a body(200), a pulley(300), an impeller(500), and an electronic clutch member. The body is formed so that cooling water flows. The pulley is rotatably coupled in one side of the body and receives power through a crank shaft of an engine. The impeller is coupled in one side terminal part of the main shaft(400), rotates according to the rotation of the pulley, and pumps the cooling water. The electronic clutch member is installed on the inner side of the pulley and delivers or blocks a driving force of the pulley to the main shaft. |
