For blocking pin 15 between friction plate skeleton 42 and clutch-pedal support 41, the effect of blocking pin 15 is to prevent friction plate
Opposite clutch-pedal support is done when skeleton and friction plate are rotated with clutch-pedal support slides in the circumferential direction, to ensure clutch just
Often work.When clutch works normally, friction plate skeleton and friction plate should be revolved with clutch-pedal support around the same central point
Turn, after friction plate outwardly opens, friction plate skeleton should be partially disengaged (close when Ying Shicong friction plate is closed with clutch-pedal support
The state of closure becomes the state that the part after friction plate outwardly opens loosens), and cannot completely disengage, because, clutch
After bracket stops operating, friction plate skeleton and friction plate should be able to be pulled back by two tension springs at friction plate skeleton both ends.It is existing
Due to not designing blocking pin 15 in technology, the contact surface for causing friction plate skeleton and clutch-pedal support skids, friction plate skeleton
The opposite clutch-pedal support of meeting is done to be slided in the circumferential direction, so that friction plate skeleton and clutch-pedal support are complete after friction plate is opened
Total detachment causes the dislocation deformation of two tension springs at friction plate skeleton both ends, will affect the normal work of clutch in this way.
As shown in Fig. 7-Figure 11, Figure 21, Figure 22, each Flywheel disc outer rim is symmetrical arranged two reset square holes 23;At two
Two pressure plates 8 are symmetrical arranged on the outside of two impact blocks 3 between Flywheel disc;Two flywheels are inserted at the both ends of every block pressur plate 8 respectively
In the ipsilateral reset square hole 23 of two of disk;Two of two pressure plates 8 are connected to one with reset tension spring 24 is passed through between side respectively
It rises.
As shown in Figure 13, Figure 15, main support 10 has an axis hole 16 and a protruding shaft 17;The motor shaft of direct current generator 7
It is mounted in the axis hole 16 on main support 10 by bearing;Driving gear 6 is sleeved on motor shaft;Driven gear 5 and driving tooth
6 engagement connection of wheel;Driven gear 5 is mounted in the protruding shaft 17 of main support 10 by bearing;The preceding inner ring of rear flywheel disk 22 passes through
Bearing is mounted on main shaft 1 (positioned at the rear end of main shaft 1);The rear inner ring of rear flywheel disk 22 is mounted on main support 10 by bearing 13
Protruding shaft 17 on (positioned at the front end of main support 10);Driven gear 5 is fixedly connected with clutch-pedal support 41, and the two is integrated.
Main support 10 is both electric machine support (motor shaft of bearing direct current generator 7), while also acting as bearing driven gear 6, clutch branch
The effect of frame 41 and rear flywheel disk 22.
The direct current generator is the direct current generator of voltage 12V, power 100-150W, 10000 turns of revolving speed, outer diameter 550mm, just
In vehicle-mounted use.By increasing the thickness of tension spring and/or reducing the length of tension spring, hitting power can be made to reach 500-600N.M.
Working principle of the utility model is: motor drives driving gear, driving gear drives driven gear, driven gear band
Clutch is moved, the friction plate on clutch acts on flywheel, and flywheel both ends there are two pressure plates, and the pressing plate on flywheel is with flywheel turns
And risen to both ends, meanwhile, impact block strikes rising on convex surface in spindle cam, is acted on active force by sleeve by main shaft
(pine) operation is tightened in realizing on nut or bolt;In the moment (when maximum force) of stall, slipping of clutch, clutch with
Flywheel separates, and flywheel stalling, two pressure plates are retracted by tension spring, so that impact block is restored to the original state (homing), restarts next
Working cycles.
The course of work of the utility model is:
When direct current generator 7 is started to work, it is driven by driving gear 6, driven gear 5, drives centrifugal clutch device
(i.e. clutch 4) rotation, motor dallies at this time;When direct current generator 7 is rotated up to certain revolving speed, work of the clutch in centrifugal force
Under, open clutch friction plate 43 (i.e. state A when clutch friction plate in Fig. 2 is opened), clutch friction plate 43 with
Friction sleeve 14 on flywheel contacts, and drives connected flywheel 2 to rotate, and the pressing plate 8 on flywheel is driven to rotate;Flywheel turns
Speed gradually increases, and when the energy accumulation of flywheel is to certain value, pressing plate 8 moves quickly into multiple under the action of rotary centrifugal force
Top in the square hole 23 of position, pressing plate 8 are separated with eccentric impact block 3;Eccentric impact block 3 also under the influence of centrifugal force, turns around pin shaft
Dynamic, a lighter impact downwards of eccentric impact block plays on convex surface (the i.e. work of impact block shown in Figure 22 in spindle cam 12
When state);Main shaft 1 rotates under the percussion of eccentric impact block, drives the sleeve 11 (driving end) of shaft end to rotate, tightens
(pine) nut or screw.
When nut or screw are screwed to bottom, main shaft 1, which is plugged, turns motionless, and in the moment of stall, active force is maximum at this time,
Direct current generator 7 overloads, and 4 momentary slip of clutch is interrupted the transmitting of torque, to protect the overload of motor, at this point, clutch friction
Piece 43 resets (i.e. state when clutch friction plate in Fig. 2 is closed under the restoring force effect of returning spring (i.e. tension spring 45)
B), centrifuge friction plate 43 is separated with the friction sleeve 14 on flywheel, and clutch does not drive flywheel, and flywheel 2 stops rotating;Flywheel is not
Turn just there is no rotary centrifugal force, the tension spring 24 that is reset under the reset pulling force effect of reset tension spring 24 of two pressure plates 8 retracts, and presses
Plate 8 is pressed in again on eccentric impact block 3, and bias hits block reset, and (that leaves main shaft plays convex surface, that is, returns to shock shown in Figure 21
State when block reset);At this point, motor dallies again;When motor is rotated up to certain revolving speed, clutch is in centrifugal force
Under effect, clutch friction plate is opened, friction plate is contacted with the friction sleeve on flywheel, connected flywheel turns are driven,
And drive press plate rotary on flywheel;Into next working cycles.
