Abstract

A mixed friction clutch driven disk assembly belongs to the automotive components technical field, which is characterized in that: three groups of normal friction pieces and three groups ceramic pieces are distributively arranged and fixed on a wave -shaped piece and a sector-shaped piece in the interphase way, the wave-shaped piece and the sector-shaped piece are respectively fixed on a driven disk. The beneficial effects are that: 1. the utility model has smooth splice, can bear high temperature, has no ablation; 2. the skid phenomenon is few, twisting ability is strong, the overloading ability of the vehicles is strong; 3. the service lives of the flywheel and the platen are longer; 4. compared with the original structure, the whole costs are only increased about 1.5 percent, but the performance cost ratio can be improved more than 5 percent.

Description

Mixed friction formula clutch driven disc assembly

Technical field:

The utility model belongs to technical field of automobile components.

Background technique:

Automobile is mature on the whole with the present development of clutch driven disc assembly, though the structural type that each manufacturing firm adopts and the friction material of use have nothing in common with each other, but on same clutch driven disc assembly, all use with a kind of friction material, it is the composite of wire and non-metallic fiber, carbon dust and solid gum that friction plate uses maximum, and its shortcoming is non-refractory, easily ablate, torque transmission capacity is low; And it is newer ceramic plate friction material, though high temperature resistant, torque transmission capacity is strong, simultaneously flywheel and platen is caused heavy wear.

Summary of the invention:

Technical problem to be solved in the utility model is:

Provide a kind of both can be high temperature resistant, torque transmission capacity is strong, flywheel and platen is not caused the mixed friction formula clutch driven disc assembly of heavy wear again.

The technical solution of the utility model is as follows:

Being distributed alternately to arrange by three groups of common friction plates and three groups of ceramic plates is fixed on corrugated sheet and the fanning strip, and corrugated sheet and fanning strip are separately fixed on the driven disc.

The beneficial effects of the utility model are:

1, joint is smooth-going, high temperature resistant, does not ablate;

2, skidding alleviates, and torque transmission capacity is strong, and the overloading wagon ability is strong;

3, flywheel and platen are longer working life;

4, whole cost only increases about 1.5% than original structure, and cost performance can improve more than 5%.

Description of drawings:

Fig. 1 is a structural drawing of the present utility model;

Wherein: the 1st, rivet, the 2nd, friction plate, the 3rd, corrugated sheet, the 4th, fanning strip, the 5th, ceramic plate, the 6th is on the driven disc.

Embodiment:

Below in conjunction with accompanying drawing the utility model is described further;

Common friction plate described in the utility model is the composite by wire and non-metallic fiber, carbon dust and solid gum.

Working principle: in clutch when work,, clutch driven disc assembly friction surface pressurized is delivered to gearbox by frictional force with the moment of torsion of motor.

For making the wearing and tearing thickness synchronised of two kinds of friction plates, we this is calculated and test result to select only distribution area the longest working life to guarantee assembly.

Working procedure: when clutch separation engaged, because the corrugated sheet effect, platen contacted with common friction plate earlier, contacted with ceramic plate again, and (engaging smooth-going) this moment, all rubbing surface entered working state, produced frictional force jointly with transmitting torque; Ceramic plate in the work can account for about 1/3rd of whole torque transmission capacity, so whole torque transmission capacity has improved more than 8% because friction factor is big; This kind clutch drived disk assy has improved the overall work ability of clutch under all constant situation of friction radius and impacting force.Two kinds of friction plates wear and tear synchronously simultaneously, suit in the clutch process in gearshift, and common friction plate has moment slipping protection effect, and this not only makes cycling start, gearshift steadily, also motor, flywheel and platen has been played protective action.

Claims

1, a kind of mixed friction formula clutch driven disc assembly, form by corrugated sheet, fanning strip, driven disc, it is characterized in that: being distributed alternately to arrange by three groups of common friction plates and three groups of ceramic plates is fixed on corrugated sheet and the fanning strip, and corrugated sheet and fanning strip are separately fixed on the driven disc.
