Pass electric signal.In addition, controller 8 can be sent out in time by comparing the signal of motor speed sensor 2 and output shaft sensor 9
The failure of now deceleration mechanism helps to improve the security level that electricity drives actuator.
Specifically, in the two schemes of above-mentioned deceleration mechanism, the course of work are as follows:
In the first scheme, when electricity drives actuator work, the work of driving motor 1 revolves the input gear 10 in shaft
Turn, and then drive 5 rotation of planetary gear, completes primary speed-down.Planetary gear 5 is also rotated with dynamic crankshaft 6 at the same time as rotation, bent
The rotation of axis 6 drives external gear 7 to be eccentrically rotated, and external gear 7 is while being revolved, also in the work of secondary annulus 12
Slow rotation occurs with lower, to complete second level deceleration.When external gear 7 carries out rotation, crankshaft 6, planetary gear 5, output method
Orchid 14 can also synchronize the axis around output shaft 3 and be rotated.The revolving speed and torque of driving motor 1 after double reduction torque increase from
The output of 14 side of output flange.In above process, the angle that motor speed sensor 2 and output shaft sensor 9 will test
Degree (angular speed) information feeds back to controller 8, and the sense of motor speed sensor 2 and output shaft sensor 9 is handled by controller 8
Signal is surveyed, and adjusts the output revolving speed of driving motor 1 according to the processing result of sensing signal, and feed back electricity to entire car controller
Drive the state of actuator.
For clutch, since it is different with active force required when separation in closure, it is therefore desirable to pass through spring
15 balance the active force in clutch separation and closing course, guarantee the steady defeated of driving motor 1 to drive actuator by electricity
Out.For normally open clutch, when clutch is opened, during output flange 14 rotates, spring 15 gradually reduces simultaneously
Store energy；When clutch closure, output flange 14 is inverted, and the energy being stored in spring 15 gradually discharges, and compensates for drive
The output torque of dynamic motor 1, increases the output torque of output flange 14.It is for normally closed type clutch, then exactly the opposite.
In second scheme, when electricity drives actuator work, the input gear 10 in 1 shaft of driving motor rotates band
Dynamic first internal gear 11 rotation, completes the first order and slows down.Since the first internal gear 11 and sun gear 4 are linked together, so first
The rotation of internal gear 11 will drive planetary gear 5 and be rotated, to complete second level deceleration.Planetary gear 5 is at the same time as rotation
Also band dynamic crankshaft 6 rotates, and the rotation of crankshaft 6 driven external gear 7 to be eccentrically rotated, external gear 7 while being revolved,
Slow rotation occurs under the action of secondary annulus 12, completes the third level and slows down.When rotation occurs for external gear 7, crankshaft
6, planetary gear 5, output flange 14 can be around the axis synchronous rotaries of output shaft 3.The revolving speed and torque of driving motor 1 subtract by three-level
It is exported after fast torque increase from 14 side of output flange.Angle (angular speed) information that output shaft sensor 9 will test is fed back to
Controller 8 is handled the sensing signal of motor speed sensor 2 and output shaft sensor 9 by controller 8, and according to sensing signal
Processing result adjustment driving motor 1 output revolving speed, and to entire car controller feed back electricity drive actuator state.Spring 15
The course of work it is identical as scheme one.
Each part is described in a progressive manner in this specification, what the structure of each part stressed is
With the difference of existing structure, electricity drives the entirety of actuator and part-structure can be by the structure of the above-mentioned multiple portions of combination
It obtains.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with features of novelty.
