The technological scheme that its technical problem that solves the utility model adopts is: a kind of start-stop integrated machine coupling tuning pulley comprises belt pulley, mandrel, internal torque spring and outer torsion spring; The internal torque spring is opposite with outer torsion spring rotation direction; Described belt pulley, outer torsion spring, internal torque spring and mandrel are set in together from outside to inside successively with one heart;
The two ends of described mandrel are equipped with right support bearing and left support bearing; Also be set with the identical retainer of external diameter, retainer and belt pulley interference fit between described belt pulley and the mandrel;
The outer ring of the inner ring of described right support bearing and mandrel interference fit, right support bearing and belt pulley interference fit; The retainer outer end has installation sleeve, the outer ring of the inner ring of left support bearing and mandrel interference fit, left support bearing and the installation sleeve interference fit of retainer;
Retainer is by the relative axial position of axial limiting spare restriction retainer and mandrel, has the location convex shoulder on the mandrel, all between retainer and location convex shoulder, the two ends of internal torque spring and outer torsion spring connect with retainer and location convex shoulder respectively for internal torque spring and outer torsion spring.
Belt pulley, outer torsion spring, internal torque spring and mandrel are set in together from outside to inside successively with one heart, so that start-stop integrated machine coupling tuning pulley compact structure of the present utility model.Because the internal torque spring is opposite with outer torsion spring rotation direction, therefore, when originate mode, generator drives engine revolution by coupling tuning pulley, the output of generator power, the mandrel of generator and coupling tuning pulley by outer torsion spring with transmission of power to belt pulley, belt pulley again by belt with transmission of power to motor, realize the starting of motor.During normal mode of operation, driven by engine generator rotary work, engine power output, power is passed to belt pulley by belt, belt pulley arrives mandrel by the internal torque spring with transmission of power, and mandrel connects with generator shaft, and transmission of power is arrived generator, the realization generator generates electricity, and electrical power storage is arrived battery.Come transferring power by internal torque spring and outer torsion spring, can effectively reduce the vibration of start-stop integrated machine and the life-span of improving train.
The beneficial effects of the utility model are, start-stop integrated machine of the present utility model can effectively reduce the vibration of start-stop integrated machine and the life-span of improving train with coupling tuning pulley, lengthened the length at retainer and belt pulley interference fit position, improved the reliability of both combinations, transmitting torque increases.
