Description
Technical Field
The invention belongs to the technical field of clutches, and particularly relates to a clutch plate.
Background
The clutch plate is a composite material which takes friction as a main function and has structural performance requirements. Friction materials for motor vehicles are mainly used for producing brake linings and clutch disks. The friction materials mainly adopt asbestos-based friction materials, and with the increasing requirements on environmental protection and safety, semimetal type friction materials, composite fiber friction materials and ceramic fiber friction materials gradually appear.
Since friction materials are used in automobiles, mainly for the production of parts of braking systems and drive trains, sufficiently high and stable coefficients of friction and good wear resistance are required.
The clutch is a mechanism which carries out transmission force by means of axial compression and release by two clutch friction plates with flat surfaces. The larger the axial pressure of the two clutch plates is, the larger the generated friction force is, and the more stable and normal the transmission to the extruder is. The machine generally has smooth running and no noise under normal running conditions; the clutch plate can not slip, be clamped and be separated automatically under rated load; meanwhile, after the clutch plates are separated, the brick machine should be completely stopped without generating other noise or incomplete separation of the two clutch plates and the like. Therefore, the gap between the clutch plates in the clutch must be adjusted, and a large gap may cause the clutch plates to slip, damage the clutch plates, and a small gap may make the clutch plates not easily separated.
Some technical solutions related to clutch plates also appear in the prior art, for example, a chinese patent with application number 2009102728296 discloses a clutch plate, which is composed of a friction working layer and a structural layer: the friction working layer is a working surface; the back of the friction working layer is provided with a structural layer, the structural layer can be one or more than one layer, and can be divided into a heat transfer layer and a supporting layer according to the function, wherein the heat transfer layer can be selected according to the requirement; the friction working layer participates in friction work to provide friction and wear performance required in the using process, the structural layer does not participate in the friction work to provide other auxiliary performance for the clutch facing product, and the whole clutch facing product is formed by combining two or more layers according to the performance requirements. The friction working layer and the structural layer are combined and hot-pressed into the clutch facing, so that the comprehensive performance of the clutch facing can be improved, and the comprehensive cost is reduced. However, this solution does not solve the problem that wear is increased when the clutch plates are overheated, which seriously affects the service life of the clutch plates, and also, the friction force of the clutch plates is reduced by preventing the powder generated by the wear between the clutch plates from being discharged, which in turn affects the driving force of the clutch plates.

A clutch plate according to claim 2, characterised in that: an arc-shaped ash removal groove (16) is formed in the friction plate (15), the vent holes (21) are formed in the bottom of the ash removal groove (16), and airflow is sprayed out through the vent holes (21) to accelerate ash removal of the ash removal groove (16).
4. A clutch plate according to claim 3, characterised in that: a cavity (29) is formed in the position, corresponding to the friction plate (15), on the plate body (1), the cavity (29) is communicated with the vent hole (21) through a water channel (24), and a cork (25) is arranged in the water channel (24); cooling water is sprayed out through the vent holes (21) at high temperature, so that the temperature of the clutch plate is quickly reduced; when the clutch is in a semi-linkage state due to faults, overlarge torsion or long-time, the friction plates (15) rub violently, the temperature of the friction plates (15) rises sharply at the moment, the friction plates (15) are easy to ablate, the driving force between the friction plates (15) is reduced seriously, meanwhile, the abrasion of the plate bodies (1) is aggravated, heat is transferred to the cavity (29) through the plate bodies (1) at the moment, cooling water in the cavity (29) evaporates rapidly, the air pressure in the cavity (29) is increased, then the cork plugs (25) are flushed out from the air holes (21), gaps between the adjacent friction plates (15) are filled with the cooling water rapidly, the friction plates (15) are flushed and cooled rapidly, and further the friction force and the service life of the friction plates (15) are increased.
5. A clutch plate according to claim 4, characterised in that: and a water-absorbing felt (17) is arranged between the adjacent friction plates (15) arranged along the radius direction of the plate body (1), the distribution area of cooling water is increased through the water-absorbing felt (17), and the heat dissipation speed of the clutch plate is further improved.
6. A clutch plate according to claim 5, characterised in that: a group of branch holes (26) which are obliquely arranged are formed in the positions, close to the outer sides of the friction plates (15), of the vent holes (21), and the blockage of the vent holes (21) is reduced through the branch holes (26); an elastic membrane (27) is fixedly connected in the vent hole (21), and a small hole (28) is formed in the middle of the elastic membrane (27); the elastic membrane (27) further blocks dust from blocking the vent hole (21).
