Description
Technical field
The present invention relates to belt pulley technical field, especially a kind of start-stop integrated machine coupling tuning pulley.
Background technique
Stopping to rise system is that automobile is set up holding state, and when vehicle is during in " idling " state (red light or traffic congestion), driver is as long as slam constantly brake petal, and motor will auto extinguishing, is switched to holding state; Release the pedal, vehicle meeting moment automatic ignition, resets.Stop to rise system and can greatly reduce energy consumption and CO2 emission.In the time that system stays cool, automobile can enter province's oil condition automatically, does not discharge any gas.Start stop system kills engine in the time of vehicle idling, the fuel consumption while having reduced the race of engine and CO2 discharge.Estimate according to Bosch, start stop system can reduce under comprehensive operating mode by approximately 8% energy consumption and discharge, can reach 10%-15% at the urban district energy-saving effect blocking up.The about 400-700 dollar of incremental cost (3000-5000 yuan) of start stop system is installed, and is changed very little to existing power transmission system.Because hybrid vehicle can help energy saving, reduces CO2 discharge, improve travelling comfort, so the market demand increases day by day.
At present, the start-stop integrated machine of Valeo adopts the output shaft of motor directly to connect with the output shaft of generator by belt drive system, and the vibration in the time of starting of this structure is large, and can produce noise, affects working life.
Summary of the invention
The technical problem to be solved in the present invention is: large in order to solve the vibration of existing start-stop integrated machine, the undesirable technical problem of life-span of train, the invention provides a kind of start-stop integrated machine coupling tuning pulley, the life-span that can effectively reduce the vibration of start-stop integrated machine and improve train.
The technical solution adopted for the present invention to solve the technical problems is: a kind of start-stop integrated machine coupling tuning pulley, comprises belt pulley, mandrel, internal torque spring and outer torsion spring; Internal torque spring is contrary 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;
Between described belt pulley and mandrel, there is the retainer with belt pulley integrative-structure;
Retainer is by the relative axial position of axial limiting part restriction retainer and mandrel, on mandrel, there is location convex shoulder, internal torque spring and outer torsion spring are all between retainer and location convex shoulder, and the two ends of internal torque spring and outer torsion spring connect with retainer and location convex shoulder respectively.
Belt pulley, outer torsion spring, internal torque spring and mandrel are set in together from outside to inside successively with one heart, make start-stop integrated machine coupling tuning pulley compact structure of the present invention.Because internal torque spring is contrary with outer torsion spring rotation direction, therefore, in the time of 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 by transmission of power to belt pulley, belt pulley again by belt by transmission of power to motor, realize the starting of motor.When 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 internal torque spring by transmission of power, and mandrel connects with generator shaft, and transmission of power is arrived to generator, realize generator generating, and electrical power storage is arrived to battery.Carry out transferring power by internal torque spring and outer torsion spring, the life-span that can effectively reduce the vibration of start-stop integrated machine and improve train.
The invention has the beneficial effects as follows, in the life-span that start-stop integrated machine of the present invention can effectively reduce the vibration of start-stop integrated machine and improve train with coupling tuning pulley, belt pulley and retainer are structure as a whole, and transmitting torque increases.
