Description
Technical field
The present invention relates to belt pulley technical field, especially a kind of coupling tuning pulley.
Background technique
Namely stopping namely to play system is that holding state set up by automobile, and when vehicle is in " idling " state (red light or traffic congestion), as long as driver slams brake petal constantly, motor will auto extinguishing, is switched to holding state; Release the pedal, vehicle meeting moment automatic ignition, resets, and can not produce noise.Namely stop namely to play system and can greatly reduce energy consumption and CO2 emission.When system stays cool, automobile can enter province's oil condition automatically, does not discharge any gas.Namely stop namely to play the consumption of the energy and the discharge of carbon dioxide that system can reduce about 10% under the operating mode of city, when traffic heavy congestion, this numerical value can reach 15%, can reduce 6% under comprehensive operating mode.
Because hybrid vehicle can help energy saving, reduce CO
2discharge, raising travelling comfort, so the market demand increases day by day.
The mode that namely current realization stops namely to rise has two kinds.Mode one, vehicle is with starter motor, automatical control system, battery, generator (for battery charging); Another kind of mode, vehicle is with generator, automatical control system, battery, and namely this mode does not have starter motor, possesses start-up function by generator while possessing electricity generate function, i.e. start-stop integrated machine.Adopt start-stop integrated machine, the whole train of motor is had higher requirement, when generator is as starter motor, need the moment of torsion larger than general motor drawing generator, so to the vibration of train and the tension of belt also large many, so the shock-absorbing function of belt pulley on generator just seems particularly important.
Summary of the invention
The technical problem to be solved in the present invention is: in order to the vibration solving existing start-stop integrated machine is large, the technical problem that life-span of train is undesirable, the invention provides a kind of coupling tuning pulley.
The technical solution adopted for the present invention to solve the technical problems is: a kind of coupling tuning pulley, comprise belt pulley, mandrel, retainer, left support bearing, right support bearing, internal torque spring, outer torsion spring and axial limiting part, belt pulley is sleeved on mandrel with one heart, left support bearing and right support bearing are arranged on belt pulley two ends, the outer ring of left support bearing and right support bearing respectively with belt pulley interference fit, the inner ring of left support bearing and right support bearing and mandrel interference fit, internal torque spring housing is contained on mandrel, outer torsion spring is sleeved on internal torque spring, retainer is sleeved on mandrel, retainer and belt pulley interference fit or pass through splined, retainer is by axial limiting part axial limiting, mandrel has location convex shoulder, internal torque spring and outer torsion spring are between retainer and location convex shoulder, the end face that retainer and internal torque spring contact with outer torsion spring has the outer torsion spring holding structure of retainer internal torque spring holding structure and retainer for keeping internal torque spring and outer torsion spring, the end face that location convex shoulder on mandrel and internal torque spring contact with outer torsion spring has the outer torsion spring holding structure of mandrel internal torque spring holding structure and mandrel for keeping internal torque spring and outer torsion spring, internal torque spring is contrary with outer torsion spring rotation direction.
When generator is in originate mode, generator drives engine revolution by coupling tuning pulley, generator power exports, the mandrel of generator and coupling tuning pulley by scyewed joint by transmission of power on mandrel, mandrel by the outer torsion spring holding structure on mandrel by transmission of power to outer torsion spring, after outer torsion spring is stressed by the outer torsion spring holding structure on retainer by transmission of power to retainer, outer torsion spring produces distortion external diameter swell simultaneously, frictional force is produced by transmission of power to belt pulley with belt pulley endoporus, retainer and belt pulley are interference fit simultaneously, better by the transmission of power of outer torsion spring to belt pulley.Belt pulley again by belt by transmission of power to motor, realize the starting of motor.
During normal mode of operation, driven by engine generator rotary work, engine power exports, power is passed to belt pulley by belt, belt pulley and retainer interference fit, so be equivalent to belt pulley to give retainer by transmission of power, retainer by the internal torque spring holding structure on retainer by transmission of power to internal torque spring, torsion spring by the other end by transmission of power on the internal torque spring holding structure of mandrel, namely mandrel has been delivered to, mandrel is connected with generator shaft by screw thread, by transmission of power to generator, realize electrical power generators, and by electrical power storage to battery.
For reaching the noise that structure is simple and reduce in working procedure, reduce vibratory impulse, described mandrel internal torque spring holding structure is mandrel internal torque spring spiral terrace, the outer torsion spring holding structure of described mandrel is the outer torsion spring spiral terrace of mandrel, and the Hand of spiral of mandrel internal torque spring spiral terrace and the outer torsion spring spiral terrace of mandrel is contrary; Described retainer internal torque spring holding structure is retainer internal torque spring spiral terrace, the outer torsion spring holding structure of described retainer is the outer torsion spring spiral terrace of retainer, and the Hand of spiral of retainer internal torque spring spiral terrace and the outer torsion spring spiral terrace of retainer is contrary.
For reducing the vibration of train in working procedure further, the step surface of described mandrel internal torque spring spiral terrace offsets 5 ° ~ 15 ° along clockwise direction relative to the step surface of the outer torsion spring spiral terrace of mandrel, realize the pretension of spring, and in mode transition procedure, realize the absorption of energy, avoid rigid of transmission, also improve the life-span of spring simultaneously; The step surface of described retainer internal torque spring spiral terrace offsets 5 ° ~ 15 ° along clockwise direction relative to the step surface of the outer torsion spring spiral terrace of retainer.When deviation angle is excessive, the pretightening force of inside and outside torsion spring is larger, affect on the one hand spring working life, while can not reach good damping effect, when deviation angle is too small, in work, inoperative spring can loosen, and pretightening force is too small, thus can produce noise.
In order to the axial pre tightening force of spring is not delivered to the spring bearing at two ends, taking axial limiting part to be jump ring, making the axial pre tightening force closed loop of spring between mandrel spiral terrace and retainer spiral terrace.
Tightr in order to make to coordinate between retainer with belt pulley, the spline groove depth on described belt pulley is 0.1mm ~ 1mm; The tooth depth of the spline on retainer is 0.1mm ~ 1mm.
The invention has the beneficial effects as follows, coupling tuning pulley of the present invention effectively can reduce the vibration of start-stop integrated machine and improve life-span of train.
