Abstract
The utility model relates to a saucer diaphragm spring clutch. The saucer diaphragm spring clutch is characterized in that the structure of saucer diaphragm spring replaces traditional spiral spring structure; simultaneously, a driven plate is designed in two-stage shock absorption, and driven twisting mechanisms such as a friction plate and a taper spring are added. Thus, the clutch appliance of the utility model has the advantages of stable performance, light starting and shift, stable running, simple structure, convenient adjustment, light operation, and long service life. The pressure of the saucer diaphragm spring clutch has small influences caused by variation of external factors such as load, rotational speed, and temperature. The saucer diaphragm spring clutch can replace traditional spiral spring clutch.
Description
The utility model relates to a kind of improved automobile clutch, belongs to the vehicle transmission mechanical field.
Automobile clutch in the past as 212 type automobile clutches, adopts coil spring type clutch, by helical spring platen on the driving disc and driven disc is compressed, and reaches the purpose that transmits power.The pressure characteristic of this form clutch is linear, the impacting force receptance of factors vary to external world is bigger, variation in pressure is big in the working procedure, and job insecurity has impact as starting and gearshift, pressure descends big etc. with wearing and tearing, add that the driven disc design only is the one-level damping, shock absorption is poor, makes automobilism not steady, vibrations are big, take uncomfortable.
It is stable, the good clutch configuration of driven disc shock-absorbing performance simultaneously of non-linear, when work pressure that the purpose of this utility model provides a kind of pressure characteristic.
One of feature of the present utility model is to have adopted dish formula diaphragm spring platen structure, utilizes the nonlinear pressure characteristic of butterfly diaphragm spring, reaches the purpose of stable operation pressure.
The damping spring that another key character of the present utility model is a driven disc is a secondary, and successively working by the different damping springs of two groups of rigidity reaches the purpose of classification damping.In addition, between damping disc and driven disc shell, be provided with friction disk, and with taper spring as compressing member, utilize " zero " stiffness characteristics of taper spring to guarantee the stability of damping torque.
The utility model clutch is owing to adopted dish formula diaphragm spring platen structure and shock-absorbing performance is good, damping torque is stable driven disc structure, thereby it is little to have an influence that pressure changes by extraneous factor such as load, rotating speed, temperature etc., stable performance, starting and gearshift are light, operate steadily, and operate brisk, simple in structure, Installation and Debugging are convenient, and parts depreciation is slow, series of advantages such as long service life.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1,2,3 is dish formula diaphragm spring clutch platen part-structure figure.Wherein Fig. 1 is a front view, and Fig. 2 is a side cutaway view, Fig. 3 be among Fig. 1 B to the rotation partial view.
Fig. 4,5 is driven disc part-structure figure.Wherein Fig. 4 is a front view, and Fig. 5 is a side cutaway view.
Describe structure of the present utility model and working principle below with reference to the accompanying drawings in detail.
Among Fig. 1 to 3,1 is clutch cover, and 2 is platen, and 3 is dish formula diaphragm spring, and 4 is the diaphragm spring supporting ring, and totally two, 5 is Steel Belt, and totally three groups, 5-0 is a shape before its riveted, and 6,7,8 are rivet.The assembled relation of each several part is that dish formula diaphragm spring is between clutch cover and the platen.Dish formula diaphragm spring reaches upward, and lower support ring is fixed on the clutch cover by rivet 6.Steel Belt 5 one ends are fixed on the platen by rivet 7, and the other end is fixed on the clutch cover by rivet 8.Steel Belt 5 plays two effects, and one is that platen and clutch cover are fixed together, thereby can send the rotating power of clutch cover to platen, and another is to utilize its preformed elasticity that platen and video disc spring forward position are adjacent to.
Among Fig. 4 and Fig. 5,9 is the driven disc shell, and 10 is damping disc, and 11 is clutch disk, and 12 is shell fragment, totally nine, be evenly distributed on down clutch disk on week, and fixing by rivet 13,14 is friction plate, is fixed on the shell fragment 12 by rivet 15.16 is damping spring, totally two groups (one group two, rigidity is smaller, four of another groups, rigidity is big) six spring windows on clutch disk and the damping disc, design size makes one group of little spring of rigidity work earlier, and one group of subsequent working that rigidity is big reaches the purpose of secondary damping.Between driven disc shell and damping disc, also have friction disk 17 and taper spring 18 in addition.Taper spring plays the pressing friction dish.In addition, between driven disc shell and the clutch disk, between driven disc shell and the friction disk 17 friction pads 19 is arranged all.Driven disc shell, clutch disk, damping disc are by totally six of position limit pin 20() be fixed together.
The installation and the working principle of this clutch are as follows: clutch cover is installed on the big flywheel of motor by screw all around, by big flywheel driven rotary.Platen 2 compresses with driven disc friction plate 14 under the effect of video disc spring 3, drives the driven disc rotation.Driving torque transfers to clutch disk by shell fragment 12, by damping spring 16 two-stage dampings, friction disk 17, taper spring 18 also play the torsion pass effect in addition, unify by above-mentioned that biographies are turned round, glissando, a stable moment of torsion is provided, reaches the effect of steady transmission power.When stepping on the dynamic clutch cut-out pedal, stressed the pressing down of separation finger tip 3-1 of video disc spring 3, the edge 3-2 that it contacts with platen is that fulcrum upwarps with supporting ring 4, platen breaks away from driven disc under the effect of Steel Belt 5, thereby realizes operations such as starting or gearshift.
