Description
Technical field
This utility model belongs to Clutch Technology field, relates to driven hub in a kind of clutch
The cover structure of assembly.
Background technology
In clutch bell housing between electromotor and change speed gear box, run at vehicle
Cheng Zhong, driver can tip into or out clutch as required, make electromotor and change speed gear box
It is temporarily separated and gradually engages, with the power cut off or transmission electromotor inputs to variator.
CVT clutch is the one of clutch, and conventional CVT clutch driven hub assembly passes
The mode of torque delivery is: V band drives driven pulley, and driven pulley drives hoof block, hoof block
Delivering torque to centrifugal cover cap after throwing away, centrifugal cover cap is delivered torque to by spline
Transmission input shaft.There is certain restriction in this transmission way of torque, to hoof block with from
Transmit the stability of moment of torsion after heart cover cap instantaneous touch, smoothness requires the highest.
Disclosed in the structure such as Chinese patent literature of existing centrifugal cover cap a kind of centrifugal from
Clutch [Authorization Notice No. CN204371989 U], the cover cap disclosed in this patent is one
Body structure, act on cover cap inwall by friction plate and drive cover cap to rotate.In this patent
Friction plate and cover cap in conventional operation can normal operation, but when anxious acceleration occurs,
Friction plate can act on suddenly on cover cap, and now the moment of torsion between cover cap and friction plate can be dashed forward
So become is the biggest, it may appear that bigger impact peak value moment, is easily caused in driven hub
Assembly shake is relatively big, and electromotor has and significantly trembles sense, and transmission band there will be fracture, becomes
The failure phenomenons such as speed case bearing of input shaft damage.
Summary of the invention
The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that
The cover structure of driven hub assembly in a kind of clutch, the technology that this utility model solves is asked
Topic is to reduce torque instantaneous between hoof block and cover cap in the case of anxious acceleration.
The purpose of this utility model can be realized by following technical proposal:

Recess one positioning recess two one to one, described positioning recess one and positioning recess two are right
Form positioning recess together, in described positioning recess, be provided with elastic component, the two of described elastic component
End all simultaneously with the sidewall of positioning recess one and positioning recess two against.
Specific works principle is as follows: the hoof block of driven hub assembly is positioned at centrifugal cover cap, V
Band drive driven pulley, driven pulley drive hoof block throw away and act on centrifugal cover cap from
And driving centrifugal cover cap to rotate, centrifugal cover cap is rotated by elastic component band nutating disk, passes
Moving plate drives transmission input shaft to rotate；When there is anxious acceleration, hoof block drives centrifugal cover
Lid rotates, and centrifugal cover cap is acted on elastic component, then delivered torque to by elastic component
Drive plate, owing to elastic component has certain elasticity, can absorb the moment of a part, and
The moment of this absorption is discharged smoothly power transmission to drive plate so that centrifugal cover cap with
Instantaneous torque size between hoof block diminishes, it is to avoid the shake of driven hub assembly is relatively big, sends out
Motivation has significantly trembles sense, and transmission band there will be the situation of fracture, also reduces biography simultaneously
Instantaneous torque size between Moving plate and transmission input shaft, it is to avoid transmission input shaft
The situation of bearing damage；The position that arranges of elastic component makes elastic component can absorb a part
Drive plate and centrifugal cover cap energy synchronous axial system when can guarantee that normal use in the case of moment.
In above-mentioned clutch in the cover structure of driven hub assembly, described elastic component is
Spring, is equipped with shock stop pin in described spring.Spring can be played overload protection by shock stop pin
Effect, meanwhile, it is capable to effectively eliminate spring transmission moment of torsion during produce vibrations
And noise.
As another kind of situation, the cover structure of driven hub assembly in above-mentioned clutch
In, described elastic component is block rubber.Block rubber is for having elasticity, when anxious acceleration, and rubber
Blob of viscose can be absorbed a part of moment by compression, drive plate and centrifugal cover cap when normal use
Can synchronous axial system.
In above-mentioned clutch in the cover structure of driven hub assembly, described positioning recess
The lower port of one is blind end, and the edge of described drive plate has the spacing ring of protrusion relatively,
Described spacing ring is positioned at the lower section of positioning recess two.This structure ensures that elastic component is always positioned at
In positioning recess.
In above-mentioned clutch in the cover structure of driven hub assembly, described cover structure
Also include that seal cover board, described seal cover board are fixed on drive plate and seal cover board can be by
Positioning recess is completely covered.This structure ensures that elastic component is always positioned in positioning recess.
Compared with prior art, in this clutch, the cover structure of driven hub assembly is occurring
During anxious acceleration so that centrifugal instantaneous torque size between cover cap and hoof block diminishes, and has
Avoiding the shake of driven hub assembly relatively big, electromotor has and significantly trembles sense, transmission band meeting
The advantage that the situation of fracture occurs；The most also reduce between drive plate and transmission input shaft
Instantaneous torque size, there is situation excellent avoiding transmission input shaft bearing damage
Point.
