Abstract
The invention provides a compensation mechanism of a diaphragm spring clutch. The compensation mechanism aims to lower the separating force of a friction plate of the diaphragm spring clutch after abrasion, the pedal force of the clutch is made to be within a comfortable and reasonable range, and thus a driver can drive more comfortably. A compensation spring is mounted between a cover and a diaphragm spring, the compensation spring is in a circular ring shape with the axis of a clutch assembly being used as the center, and a rivet groove of the compensation spring is clamped on a supporting rivet of the cover and the diaphragm spring. A compensation spring supporting ring is mounted at the position, abutting against the supporting rivet, between the compensation spring and the diaphragm spring, and an inner hole of the cover is supported and pressed on the compensation spring. The compensation mechanism of the diaphragm spring clutch is simple in structure, convenient to assemble, and capable of effectively lowering the separating force of the friction plate after abrasion and improving the comfort degree of the driver.
Description
Technical field
The invention belongs to auto parts machinery field.
Background technique
Automobile clutch plays torsion pass, cuts off the multiple functions such as power, vibration damping and overload protection, the performance of the whole automobile of good bad influence of its quality in power train.In vehicle traveling process, after clutch Long-Time Service, clutch-pedal load can increase gradually, if be greater than the power that can adapt to of driver, affects the driving experience of driver exactly, have impact on the comfort of driver.In the whole working procedure of clutch, due to the wearing and tearing of friction plate, the impacting force of clutch and Separating force all can increase, and cause clutch-pedal load to increase, and feel heavy, reduce the travelling comfort of driver during driver's stepping on clutch pedal.
Summary of the invention
The object of the invention is the Separating force after reducing diaphragm spring clutch friction disc wear, make clutch foot plate power in comfortable rational scope, make driver drive the compensation mechanism of more comfortable diaphragm spring clutch.
The present invention is provided with counterbalance spring between lid with diaphragm spring, circular centered by clutch assembly axis of counterbalance spring, and the rivet groove of counterbalance spring is stuck on the support rivet of connecting cover and diaphragm spring; Between counterbalance spring and diaphragm spring, near support rivet place, counterbalance spring support ring is installed; The endoporus of lid supports and is pressed on counterbalance spring.
Structure of the present invention is simple, is convenient to assembling.Effectively can reduce the Separating force after friction disc wear, improve the travelling comfort of driver.
Accompanying drawing explanation
Fig. 1 is structure of the present invention (pre-scuffing condition, the equilibrant force provided is little) sectional view;
Fig. 2 is structure of the present invention (the rear state of wearing and tearing, the equilibrant force provided is large) sectional view;
Fig. 3 is counterbalance spring structural representation of the present invention.
Embodiment
The present invention is provided with counterbalance spring 4 between lid 1 and diaphragm spring 5, circular centered by clutch assembly axis of counterbalance spring 4, and the rivet groove 6 of counterbalance spring 4 is stuck in connecting cover 1 with on the support rivet 2 of diaphragm spring 5; Between counterbalance spring 4 and diaphragm spring 5, near support rivet 2 place, counterbalance spring support ring 3 is installed; The endoporus of lid 1 supports and is pressed on counterbalance spring 4.
Supporting ring of the present invention and counterbalance spring are arranged between diaphragm spring and lid, with supporting rivet, original supporting ring, counterbalance spring supporting ring and diaphragm spring are riveted together.The fulcrum of counterbalance spring one end is covering, and the other end fulcrum is on supporting ring.
When clutch works, because friction plate both sides can produce Relative friction with flywheel surface and platen surface respectively, along with the time used increases, the wear extent of friction plate is larger, at this moment in clutch assembly, the impacting force of diaphragm spring can become large gradually, and Separating force also can increase, the pedal force also corresponding increase of clutch, foot treadle can be heavier, produces larger impact to the driving experience of driver.In order to when ensureing that clutch separation power becomes large, do not affect the driving experience of driver, add counterbalance spring, due to the wearing and tearing of friction plate, platen can be moved to the left, the angle of diaphragm spring and lid becomes large, near counterbalance spring side because leverage can by supporting ring compression compensation spring, counterbalance spring impacting force is increased, power-assisted effect can be produced to Separating force when diaphragm spring is separated, thus reduce the Separating force of clutch, and then the effect of the pedal force of reduction clutch, improve the travelling comfort of driving.
The present invention adds counterbalance spring structure in conventional clutch, makes after clutch friction pad wear, when Separating force increases, reduces Separating force.When after friction disc wear, platen can be moved to the left, now the large end of diaphragm spring also can be moved to the left, angle between diaphragm spring and lid increases, near counterbalance spring side because leverage can move right, compression compensation spring, makes the impacting force of counterbalance spring increase, release bearing can be helped when disengaged to promote diaphragm spring be separated, and then play the effect reducing pedal force.
The Separating force Data Comparison of the diaphragm spring clutch of common diaphragm spring clutch and band counterbalance spring mechanism:
As can be seen from above Data Comparison, there is the clutch of compensation mechanism can reduce Separating force size between 100-420N.
