Description
Technical field
The present invention relates to the clutch in auto parts field, specially a kind of friction clutch.
Background technique
It is also a kind of clutch with the longest history that friction clutch, which is most widely used, it is substantially by initiative part
Divide, three parts of secondary part and hold-down mechanism form.When hold-down mechanism not to driving disc spacing pressing apply pressure when, active part and from
The rubbing surface of dynamic part does not contact, and clutch is in discrete state, when hold-down mechanism applies pressure to driving disc spacing pressing, active part
It contacts with each other with secondary part rubbing surface, clutch is in engagement state, and can transfer motion power.Current existing friction clutch
In bonding state transfer motion power, hold-down mechanism is needed to provide biggish pressure.
Summary of the invention
The purpose of the present invention is to provide a kind of friction clutch, with solve it is mentioned above in the background art friction from
When clutch engagement state transfer motion power, the problem of friction clutch hold-down mechanism is to active part offer larger pressure is needed.
To achieve the above object, the invention provides the following technical scheme:
A kind of friction clutch, including power input shaft, hydraulic cylinder, feather key, driving disc spacing pressing, reset spring, spring arch clasp, from
Moving plate, power output gear and bearing.The hydraulic cylinder is fixedly connected on power input shaft, and the driving disc spacing pressing is connected by feather key
It connects on power input shaft, the power output gear is fixedly connected on the right side of driven disc, the bearing and the fixed company of driven disc
It connects, the bearing and power input shaft are flexibly connected, and reset spring is equipped between the driving disc spacing pressing and spring arch clasp.
Further, the contact with each other shape of rubbing surface of the driving disc spacing pressing and driven disc is mutual corresponding truncated cone-shaped side
Face part, and the axis of truncated cone-shaped and power input shaft axis are to be overlapped.
Compared with prior art, the beneficial effects of the present invention are: this kind of friction clutch realize in the past rubbed from
The change of clutch, the part of change are the shapes of driving disc spacing pressing and driven disc contact rubbing surface.This kind of friction clutch driving disc spacing pressing and
The shape for the rubbing surface that driven disc contacts with each other is mutual corresponding truncated cone-shaped lateral parts, and the axis and power of truncated cone-shaped
The axis of input shaft is to be overlapped.The friction clutch of this structure is in transfer motion power, according to the equilibrium condition of power, driving disc spacing pressing
Normal pressure between driven disc contact rubbing surface is greater than hold-down mechanism hydraulic cylinder to driving disc spacing pressing along the pressure of power input shaft axial direction
Power.So the clutch of this contact rubbing surface structure can accomplish that hold-down mechanism hydraulic cylinder is to driving disc spacing pressing along power input shaft
It is axial that a lesser pressure is provided, driving disc spacing pressing and driven disc can be made to contact between rubbing surface and generate biggish normal pressure.And
And the ratio of truncated cone-shaped high (H) and truncated cone-shaped bus length (L) is bigger, generates between driving disc spacing pressing and driven disc contact rubbing surface
The ratio for the pressure that normal pressure and hydraulic cylinder axially provide driving disc spacing pressing along power input shaft is also bigger.Therefore, the clutch
Hold-down mechanism to driving disc spacing pressing provide a lesser pressure, so that it may so that driving disc spacing pressing and driven disc contact rubbing surface between generate
Biggish normal pressure transmits torque.It is the design that a comparison has innovation.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Whole description, it is clear that described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, shall fall within the protection scope of the present invention interior.Fig. 1, Fig. 2 are please referred to, the present invention provides a kind of technical solution:
A kind of friction clutch, including power input shaft 1, hydraulic cylinder 2, feather key 3, driving disc spacing pressing 4, reset spring 5, Spring Card
Ring 6, driven disc 7, power output gear 8, bearing 9.Hydraulic cylinder 2 is fixedly connected on power input shaft 1, and driving disc spacing pressing 4 passes through cunning
Key 3 is connected on power input shaft 1, and power output gear 8 is fixedly connected on 7 right side of driven disc, and bearing 9 and driven disc 7 are fixed
Connection, bearing 9 and power input shaft 1 are flexibly connected, and reset spring 5 is equipped between driving disc spacing pressing 4 and spring arch clasp 6.Working principle:
This kind of clutch is a power drive mechanism, and when not transfer motion power, hold-down mechanism hydraulic cylinder 2 does not generate pressure to driving disc spacing pressing 4
Power, under the action of reset spring 5, driving disc spacing pressing 4 and driven disc 7 contact rubbing surface separation, and when transfer motion power, hydraulic cylinder 2 is right
Driving disc spacing pressing 4 generates pressure, and driving disc spacing pressing 4 and driven disc 7 contact rubbing surface and gradually engage, and during transfer motion power, generate
It relatively rotates.Friction clutch relies primarily on contact surface friction and generates frictional force transmitting torque, it may also be said to is rubbed using generation
It wipes the normal pressure that driving disc spacing pressing 4 required for power and driven disc 7 contact between rubbing surface and transmits torque.Due to the clutch driving plate
4 and driven disc 7 to contact the shape of rubbing surface be mutual corresponding truncated cone-shaped lateral parts, and the axis of truncated cone-shaped and power are defeated
Entering axis axis is to be overlapped.The clutch of this structure is in transfer motion power, according to the equilibrium condition of power, driving disc spacing pressing 4 and driven
The normal pressure that disk 7 contacts between rubbing surface is centainly greater than hold-down mechanism hydraulic cylinder 2 and axially mentions to driving disc spacing pressing 4 along power input shaft 1
The pressure of confession.So the clutch of this contact rubbing surface structure can accomplish that hold-down mechanism hydraulic cylinder 2 is to driving disc spacing pressing 4 along dynamic
Power input shaft 1 is axial to provide a lesser pressure.It can make to generate between driving disc spacing pressing 4 and the contact rubbing surface of driven disc 7 larger
Normal pressure.And the ratio of the bus length (L) of the height (H) and truncated cone-shaped of truncated cone-shaped is bigger, and driving disc spacing pressing 4 connects with driven disc 7
The ratio for the pressure that the normal pressure and hydraulic cylinder 2 generated between touching rubbing surface axially provides driving disc spacing pressing 4 along power input shaft 1
It is bigger.Therefore the hold-down mechanism hydraulic cylinder 2 of the clutch provides a lesser pressure to driving disc spacing pressing 4, so that it may so that actively
Disk 4 and driven disc 7, which contact, generates biggish normal pressure transmitting torque between rubbing surface.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understand without departing from the principles and spirit of the present invention, these embodiments can be carried out with a variety of variations, modification, replacement
And modification, the scope of the present invention is defined by the appended.
