Description
Technical field
The present invention relates to the belt pulley technical field, the tuning belt pulley of especially a kind of coupling.
Background technique
Promptly stopping promptly to rise system is that automobile is set up holding state, and when vehicle is in " idling " state (red light or traffic congestion), the driver is as long as slam brake petal constantly, and motor will auto extinguishing, switches to holding state; Release the pedal, vehicle can be lighted a fire moment automatically, resets, and can not produce noise.Promptly stop promptly to rise system and can significantly reduce energy consumption and CO2 emission.When system stayed cool, automobile can get into automatically and economize oil condition, does not discharge any gas.Promptly stop promptly to rise system can reduce the energy about 10% under the operating mode of city consumption and emission of carbon-dioxide, when traffic was seriously blocked up, this numerical value can reach 15%, under comprehensive operating mode, can reduce 6%.
Because hybrid vehicle can help energy saving, reduce CO
2Discharging, raising travelling comfort are so the market demand increases day by day.
The mode that realization at present promptly stops promptly to rise has two kinds.Mode one, vehicle have starter motor, automatical control system, battery, generator (for battery charge); Another kind of mode, vehicle has generator, automatical control system, battery, and promptly this mode does not have starter motor, when possessing electricity generate function, possesses start-up function by generator, i.e. the start-stop integrated machine.Adopt the start-stop integrated machine; Whole train to motor is had higher requirement; When generator during as starter motor; Moment of torsion that need be bigger than general motor drawing generator is so to also big many of the tension of the vibration of train and belt, so that the shock-absorbing function of the belt pulley on the generator just seems is particularly important.
Summary of the invention
The technical problem that the present invention will solve is: big in order to solve the vibration that has the start-stop integrated machine now, and unfavorable technical problem of the life-span of train, the present invention provides a kind of coupling tuning belt pulley.
The technical solution adopted for the present invention to solve the technical problems is: the tuning belt pulley of a kind of coupling; Comprise belt pulley, mandrel, retainer, left spring bearing, right spring bearing, internal torque spring, outer torsion spring and axial limiting spare; Belt pulley is sleeved on the mandrel with one heart; A left side spring bearing and right spring bearing are installed in the belt pulley two ends, the outer ring of left spring bearing and right spring bearing respectively with belt pulley interference fit, the inner ring of left spring bearing and right spring bearing and mandrel interference fit; The internal torque spring housing is contained on the mandrel; Outer torsion spring is sleeved on the internal torque spring, and retainer is sleeved on the mandrel, retainer and belt pulley interference fit or pass through splined; Retainer is through axial limiting spare axial limiting; Have the location convex shoulder on the mandrel, internal torque spring and outer torsion spring are between retainer and location convex shoulder, and retainer is useful on the retainer internal torque spring holding structure and the outer torsion spring of retainer that keep internal torque spring and outer torsion spring with the end face that the internal torque spring contacts with outer torsion spring and keeps structure; Location convex shoulder on the mandrel is useful on the mandrel internal torque spring holding structure and the outer torsion spring of mandrel that keep internal torque spring and outer torsion spring with the end face that the internal torque spring contacts with outer torsion spring and keeps structure, and the internal torque spring is opposite with outer torsion spring rotation direction.
When generator is in originate mode; Generator drives engine revolution through the tuning belt pulley of coupling, the output of generator power, the mandrel of generator and the tuning belt pulley of coupling through scyewed joint with transmission of power to mandrel; Mandrel keeps structure that transmission of power is arrived outer torsion spring through the outer torsion spring on the mandrel; The stressed back of outer torsion spring keeps structure to give retainer with transmission of power through the outer torsion spring on the retainer, and simultaneously outer torsion spring produces the distortion external diameter and rises greatly, produces frictional force with the belt pulley endoporus and gives belt pulley with transmission of power; Retainer and belt pulley are interference fit simultaneously, better give belt pulley with the transmission of power of outer torsion spring.Belt pulley arrives motor through belt with transmission of power again, realizes the starting of motor.
During normal mode of operation, engine drives generator rotary work, engine power output; Power is passed to belt pulley through belt, and belt pulley and retainer interference fit have been given retainer so be equivalent to belt pulley with transmission of power; Retainer is given the internal torque spring through the internal torque spring holding structure on the retainer with transmission of power, torsion spring through the other end with transmission of power to the internal torque spring holding structure of mandrel, promptly be delivered to mandrel; Mandrel connects with generator shaft through screw thread; Transmission of power to generator, is realized generator for electricity generation, and electrical power storage is arrived battery.
For reaching simple in structure and reducing the noise in the working procedure; Reduce vibratory impulse; Described mandrel internal torque spring holding structure is a mandrel internal torque spring spiral terrace; It is the outer torsion spring spiral terrace of mandrel that the outer torsion spring of described mandrel keeps structure, and the Hand of spiral of the outer torsion spring spiral terrace of mandrel internal torque spring spiral terrace and mandrel is opposite; Described retainer internal torque spring holding structure is a retainer internal torque spring spiral terrace; It is the outer torsion spring spiral terrace of retainer that the outer torsion spring of described retainer keeps structure, and the Hand of spiral of the outer torsion spring spiral terrace of retainer internal torque spring spiral terrace and retainer is opposite.
For further reducing the vibration of train in the working procedure; The step surface of described mandrel internal torque spring spiral terrace squints 5 °～15 ° along clockwise direction with respect to the step surface of the outer torsion spring spiral terrace of mandrel; Realize the pretension of spring, and in the mode switch process, realize the absorption of energy; Avoid rigid of transmission, the life-span of also improving spring simultaneously; The step surface of described retainer internal torque spring spiral terrace squints 5 °～15 ° along clockwise direction with respect to the step surface of the outer torsion spring spiral terrace of retainer.When deviation angle was excessive, the pretightening force of inside and outside torsion spring was big more, influenced on the one hand spring working life, can not reach good damping effect simultaneously, and when deviation angle was too small, the inoperative spring can become flexible in the work, and pretightening force is too small, thereby can produce noise.
In order the axial pre tightening force of spring not to be delivered to the spring bearing at two ends, taking axial limiting spare is jump ring, and the axial pre tightening force closed loop that makes spring is between mandrel spiral terrace and retainer spiral terrace.
Cooperate closelyr between retainer and the belt pulley in order to make, the spline groove depth on the described belt pulley is 0.1mm～1mm; The tooth depth of the spline on the retainer is 0.1mm～1mm.
The invention has the beneficial effects as follows that the tuning belt pulley of coupling of the present invention can effectively reduce the vibration of start-stop integrated machine and the life-span of improving train.
