Description
Technical field
The present invention relates to a kind of vehicle that is used for, especially for the torsion damping device of clutch driven disc or change speed gear box.
Background technology
The moment of torsion of (four stroke) driving engine is pulsation output, has so just applied the external force of reversing of one-period variation to bent axle, and it is fast to make the bent axle rotation neglect slowly suddenly, and the cylinder number of driving engine is few more obvious more.In addition, when vehicle starting,, torsion sharp increase suddenly stops working owing to can making engine speed plunge.
The power-transfer clutch secondary part is made up of monolithic, biplate or multi-disc clutch plate, and it transmits A end by friction power is passed to the input shaft of change speed gear box.Referring to Fig. 1,2, clutch plate is made up of friction lining 1, clutch plate body 2,3 three essential parts of clutch plate hub.For fear of the resonance of rotation direction, relax the impact load that transmission system is subjected to, most of automobiles all on clutch plate attaching bumper is arranged.Bumper comprises bumper dish 4 and spiral compression spring 5 (being generally six).The bumper dish generally is riveted on the clutch plate body.Spiral compression spring is arranged on the bumper dish.Power-transfer clutch in conjunction with the time, the torque that driving engine sends drives clutch plate body and bumper dish and rotates together through the friction lining of the Moving plate both sides that flywheel sea platen is passed to.Clutch plate body and bumper dish are passed to clutch plate hub to torque by spiral compression spring again.Clutch plate hub drives change speed gear box input shaft 6 again and rotates.Because spiral compression spring is arranged, utilize its elasticity to absorb impact from transmission system, play buffer action, by friction torsion oscillations is decayed rapidly.But there is the limitation of two aspects in the torsional vibration damper of this routine: one can not make driving engine be reduced to below the idling speed to the natural frequency between the change-speed box, promptly can not avoid producing when idling speed the possibility of resonance; The 2nd, because clutch driven disc medi-spring corner is restricted, spring stiffness can't reduce, and effectiveness in vibration suppression is poor, is difficult to absorb well the torque ripple from driving engine.
Summary of the invention
The purpose of this invention is to provide the better vehicle torsion damping device of a kind of effectiveness in vibration suppression.
This torsion damping device comprises torsion spring, and a leg of torsion spring is connected the rotation importation of vehicle, and another leg is connected the rotation output of vehicle.
The present invention is connected with torsion spring and rotates between importation and the rotation output, utilizes its elasticity transfer torque, and the torque ripple that driving engine is produced filters out, make the moment of torsion of transmission steadily soft, play the favorable damping effect, prolong the service life of power system, improve traveling comfort.
Rotate the importation and can be the friction lining in the power-transfer clutch, clutch plate body, clutch plate hub, bumper dish; Friction lining is arranged on the end face periphery of clutch plate body, and the clutch plate body is sleeved on the clutch plate hub, and the bumper dish is captiveed joint with the clutch plate body; One leg of torsion spring is connected on clutch plate body or the bumper dish; The rotation output is a clutch plate hub.This structure replaces spiral compression spring formula vibration-proof structure conventional in the power-transfer clutch with torsion spring, can make the bigger windup-degree of generation between clutch driven disc and the change speed gear box input shaft, utilize its elasticity transfer torque, the torque ripple that driving engine is produced filters out, make the moment of torsion that is delivered to change-speed box steadily soft, play the favorable damping effect, prolong the service life of power system, improve traveling comfort.
Rotating the importation can be the leading portion that is divided into the change speed gear box input shaft of two sections of front and back, and rotating output is the back segment of change speed gear box input shaft.In this structure, the leading portion of change speed gear box input shaft rotates by the back segment that torsion spring drives the change speed gear box input shaft, and torque ripple is filtered out, and makes the moment of torsion of the back segment that is delivered to the change speed gear box input shaft steadily soft, plays the favorable damping effect.
Rotate the importation and also can be the gear on the output shaft that is sleeved on change speed gear box, the rotation output is an output shaft.In this structure, the gear of rotation rotates by the output shaft that torsion spring drives change speed gear box, and torque ripple is filtered out, and makes the moment of torsion that is delivered to output shaft steadily soft, plays the favorable damping effect, prolongs the service life of power system, improves traveling comfort.
Rotating the importation can also be for being connected the elementary mass fraction of the double mass flywheel on the engine crankshaft, and rotating output is the secondary mass part that is connected the double mass flywheel on the change speed gear box.
Double mass flywheel belongs to prior art, exactly an original flywheel is divided into two parts, a part is retained on the position of original driving engine one side, plays the effect of original flywheel, be used to start and transmit the driving torque of driving engine, this part is called elementary quality.Another part then is placed on transmission system gear shift device one side, the rotor inertia that is used to improve change-speed box, and this part is called secondary mass.In elementary mass fraction and secondary mass part cylindroid helical-coil compression spring is set circumferentially.The elementary mass fraction of driving engine is passed to the secondary mass part to torque by cylindroid helical-coil compression spring.Because cylindroid helical-coil compression spring is arranged, utilize its elasticity to absorb impact from driving engine, play buffer action.But because the cylindroid helical-coil compression spring corner is restricted, spring stiffness can't reduce, and effectiveness in vibration suppression is poor, is difficult to absorb well the torque ripple from driving engine.
The present invention is connected the torsion spring that elementary mass fraction, another leg be connected the secondary mass part by a leg and connects two parts flywheel as a whole.In this structure, the elementary mass fraction of rotation drives secondary mass by torsion spring and partly rotates, and torque ripple is filtered out, and makes the moment of torsion that is delivered to the secondary mass part steadily soft, plays the favorable damping effect.
Torsion spring is a volute spring, as plane scroll spring and truncated cone volute spring, preferred planar volute spring.
