Technical Field

The invention relates to the technical field of clutches, in particular to a friction clutch.

Background

The friction clutch is a clutch which is widely applied and has the longest history, and basically comprises a driving disc, a driven disc and a pressing mechanism. When the pressing mechanism does not apply pressure to the driven disc, the friction surfaces of the driving disc and the driven disc are not in contact, the clutch is in a separated state, when the pressing mechanism applies pressure to the driven disc, the friction surfaces of the driving disc and the driven disc of the friction clutch are in contact with each other, if the rotating speeds of the driving disc and the driven disc are the same, the driving disc and the driven disc of the friction clutch are in a completely engaged state, and if the rotating speeds of the driving disc and the driven disc are not the same, the driving disc and the driven disc of the friction clutch are in an incompletely engaged state, namely the friction clutch is in a sliding friction state. In the existing friction clutch, the material loss of the contact friction surface of the driving disc and the driven disc is large in the sliding friction state, and the service life of the friction clutch is influenced.

Disclosure of Invention

The invention aims to provide a friction clutch, which has the advantages that the material loss of the contact friction surface of a driving disc and a driven disc is very small in the sliding friction state of the driving disc and the driven disc, so as to solve the problems that the material loss of the contact friction surface of the driving disc and the driven disc of the clutch is large and the service life of the clutch is short in the sliding friction state of the friction clutch in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme:

a friction clutch comprises a driving disc and a driven disc, wherein one of the materials of the driving disc contact friction surface and the driven disc contact friction surface is metal lead or lead alloy, the other one of the materials of the driving disc contact friction surface and the driven disc contact friction surface is metal mild steel or other types of metals and metal alloys, if the material of the driving disc contact friction surface is metal lead or lead alloy, the material of the driven disc contact friction surface is metal mild steel or other types of metals and metal alloys, if the material of the driven disc contact friction surface is metal lead or lead alloy, the material of the driving disc contact friction surface is metal mild steel or other types of metals and metal alloys, and the friction of the driving disc contact surface and the driven disc contact surface is performed in liquid with better lubrication effect, namely under the condition of lubrication friction.

Furthermore, the driving disk can be used by 1 single piece or a plurality of pieces in combination, and the driven disk can be used by 1 single piece or a plurality of pieces in combination.

Furthermore, each driving disk may have one friction contact surface or two friction contact surfaces, and each driven disk may have one friction contact surface or two friction contact surfaces.

Compared with the prior art, the invention has the beneficial effects that; the metal lead or lead alloy and the metal mild steel or other kinds of metals and metal alloys are respectively used as materials of the contact friction surfaces of the driving disc and the driven disc of the friction clutch, and the friction clutch can perform sliding friction in liquid with good lubricity, namely the friction clutch has low loss when performing sliding friction under the condition of lubricating friction, thereby prolonging the service life of the friction clutch, and particularly prolonging the service life of the friction clutch which needs the driving disc and the driven disc to be in a sliding friction state for a relatively long time.
