It is fixed in the mounting hole of fan-shaped rocking arm, the other end is fixed in the mounting hole of shell.
4. the electronic speedup clutch of a kind of hybrid vehicle according to claim 1, it is characterised in that：The planet carrier
Shape be triangle, an axis is fixed on each angle of planet carrier, planetary gear, planetary gear and axis are installed on each axis
Between by bearing be connected, planetary gear is engaged with sun gear and external toothing.
5. the electronic speedup clutch of a kind of hybrid vehicle according to claim 1, it is characterised in that：The steel wire is set
In steel wire shell, steel wire shell is fixed on by bearing on shell.
6. the electronic speedup clutch of a kind of hybrid vehicle according to claim 1, it is characterised in that：The braking clamp
Pincers speedup clutch outer member top has trapezoidal groove, groove both sides to have circular through hole, brake caliper shell circular through hole to pass through pin
Axis and groove both sides circular through hole keep concentric, and brake caliper can slide on cylindrical pin again；Brake caliper shell with it is recessed
Spring is installed between slot inner wall, the displacement of brake caliper is limited by spring.
7. a kind of control method of the electronic speedup clutch of hybrid vehicle, it is characterised in that：When vehicle condition needs start
When machine works, the work of vehicle control unit controls clutch reduction motor is drawn by leadscrew-nut mechanism, pulling force sensor and steel wire
Dynamic sector rocking arm rotation, brake caliper lock sun gear, and the value of thrust measured is fed back to vehicle control device by pulling force sensor, when
Pulling force sensor numerical value meets required braking force, and decelerating motor stops rotating, and planetary gear train only has one degree of freedom, speedup at this time
Clutch is in drive state；When vehicle condition does not need engine work, controller controls decelerating motor work, passes through silk
Thick stick nut structure, pulling force sensor and the fan-shaped rocking arm of steel wire release, brake caliper returns to initial position, when pulling force sensor numerical value
When being reduced to preset value, decelerating motor is stopped, and the sun gear of planetary gear train has with engine rotation, planetary gear train at this time
Two degree of freedom, speedup clutch are in discrete state not passing power, and sun spoke plate can replace engine flywheel at this time
Rotary inertia, ensure the steady operation of engine.
