Specific embodiment
The embodiments described below with reference to the accompanying drawings are exemplary, for explaining only the invention, and cannot be construed to
Limitation of the present invention.
As depicted in figs. 1 and 2, the embodiment provides the flywheels that a kind of often engagement starts motor, including driving
Disk 1, rolling bearing 2, hub 3 and connector, in which:
The drive disk 1 is coaxially rotationally connected on crankshaft 4 by the rolling bearing 2, and the outer ring of drive disk 1 is risen
Movable tooth circle and the gear started on motor 14 are in normal meshing state, and the inner ring of drive disk 1 is equipped with rolling bearing 2, rolling bearing 2
It is fitted on crankshaft 4.
The hub 3 is coaxially fixed on the tail end of the crankshaft 4, and hub 3 and crankshaft 4 are rigidly connected, hub 3 and crankshaft 4
It rotates synchronously, the outer end face of drive disk 1 is recessed with accommodating chamber 15, and hub 3 is contained in accommodating chamber 15.
When the revolving speed of the crankshaft 4 is lower than set speed, the outer ring of the both ends of the connector and the hub 3 and
The inner ring of the drive disk 1 abuts, and such crankshaft 4, hub 3 and drive disk 1, which are realized, to be rotated synchronously, when normal starting vehicle,
It starts 14 gear of motor and drives drive disk 1 to rotate by starting gear ring, drive disk 1 drives hub 3 to rotate by connector, and band
Dynamic crankshaft 4 rotates.
When the revolving speed of the crankshaft 4 is higher than the set speed, the outer ring at the both ends of the connector and the hub 3
And the inner ring separation of the drive disk 1.
It determines to stop engine when start stop system is based on driving situation, driver but wants the continuation before engine stops completely
When driving, since 4 revolving speed of crankshaft persistently reduces, when revolving speed is lower than set speed, connector is again by hub 3 and drive disk 1
It is combined together, starts motor 14 and start, by drive disk 1, connector drives hub 3 to rotate, when 4 revolving speed of crankshaft is greater than set
When speed, the both ends of the connector are separated with the inner ring of the outer ring of the hub 3 and the drive disk 1, hub 3 and driving
Disk 1 disconnects.
Further, the connector includes freewheel 5, centrifugal pendulum 6, spring fastening 7, holddown spring 8 and support block
9, in which:
The freewheel 5 is coaxially fixed in the hub 3, and freewheel 5 is contained in the accommodating chamber of the drive disk 1
In 15, freewheel 5 and hub 3 are rotated synchronously.
The middle part of the centrifugal pendulum 6 is rotatably fixed in the disk of the freewheel 5 by shaft 16；It is described from
The both ends of heart pendulum 6 are abutted with the inner ring of the outer ring of the hub 3 and the drive disk 1 respectively, and centrifugal pendulum 6 is used as middleware,
By the effect of frictional force so that hub 3 and drive disk 1 rotate synchronously, when centrifugal pendulum 6, which turns to, to be disengaged, hub 3 with
Drive disk 1 is asynchronous.
The spring fastening 7 is fixed in the disk of freewheel 5, the both ends of the holddown spring 8 respectively with the bullet
Spring support 7 and the support block 9 are fixedly connected, one end away from the holddown spring 8 of the support block 9 and the centrifugal pendulum 6
It abuts, centrifugal pendulum 6 passes through the active force of holddown spring 8, and outer perimeter section is contacted and limited with drive disk 1, inner round portion and hub 3
It contacts and limits, centrifugal pendulum 6 links together drive disk 1 and hub 3.Set speed is related to the pressing force of holddown spring 8,
Pressing force is bigger, and set speed is bigger.
When normal starting vehicle, starts 14 gear of motor and drive drive disk 1 to rotate by starting gear ring, drive disk 1 passes through
Centrifugal pendulum 6 drives hub 3 to rotate, and freewheel 5 is driven to rotate, when 5 revolving speed of freewheel reaches set speed, centrifugal pendulum
6 under the influence of centrifugal force, overcomes the active force of holddown spring 8, centrifugal pendulum 6 is rotated around shaft 16, when revolving speed continues to increase
When, freewheel 5 is separated with drive disk 1.
It determines to stop engine when start stop system is based on driving situation, driver but wants the continuation before engine stops completely
When driving, 4 revolving speed of crankshaft persistently reduces, when revolving speed be lower than set speed when, centrifugal pendulum 6 under the active force of holddown spring 8, gram
It takes centrifugal force and centrifugal pendulum 6 is returned back into original state, freewheel 5 is combined together with drive disk 1 at this time, is started motor 14 and is opened
Dynamic, by drive disk 1, centrifugal pendulum 6 drives freewheel 5 to rotate, when 5 revolving speed of freewheel is greater than set speed, centrifugal pendulum 6
Rotation, starts 14 gear of motor and freewheel 5 disconnects.
Further, the freewheel 5 works as freedom in being provided with spacer pin 10 on the rotation path of the centrifugal pendulum 6
When flywheel 5 rotates more than set speed, centrifugal pendulum 6 is rotated centered on shaft 16, is supported when centrifugal pendulum 6 is turned to spacer pin 10
When connecing, the both ends of centrifugal pendulum 6 are not abutted with hub 3 and drive disk 1, and spacer pin 10 can carry out the rotation path of centrifugal pendulum 6
Limit prevents its rotation excessively, so that it during high vehicle speeds, keeps stable state.
Further, the centrifugal pendulum 6 is equipped with multiple, and multiple 6 annulars of centrifugal pendulum are fixed on the freedom at equal intervals
In the disk of flywheel 5, such driving force is evenly dispersed, and driving process is reliable and stable.
Further, the both ends of the centrifugal pendulum 6 are equipped with arc guide surface 11, and hub 3 and drive disk 1 pass through arc
Guide surface 11 gradually contacts centrifugal pendulum 6, avoids direct rigid contact, and pause and transition in rhythm or melody or abnormal sound occurs.
Further, 6 first side of centrifugal pendulum is equipped with the first groove 12, and the support block 9 presses on first groove
In 12, support block 9 passes through the active force of holddown spring 8, pushes against in the first groove 12.
Further, second side of the centrifugal pendulum 6 is equipped with the second groove 13, and the second groove 13 and the first groove 12 are diagonal
Setting, when the centrifugal pendulum 6 turns to commitment positions, the spacer pin 10 is pressed in second groove 13.
