The utility model main control strategies and main working process are：
One combination-braking
After control unit 3 receives higher level's control command, driving actuating motor 1 rotate forward (definition rotate forward for
Braking direction), actuating motor 1 drives input gear 4 to rotate forward after deceleration unit 2 increases torque, by output shaft 5, defeated
Entering gear 4 drives output gear 11 to rotate backward, and output gear 11 drives left end screw rod 12 to rotate backward, due to left piston 14
It can move axially, thus, left end screw rod 12 pushes left piston 14 to be moved to the left, and then, caliper frame 7 passes through caliper frame right side band
Right brake pad 17 is moved to be moved to the left；Meanwhile output gear 11 drives right end screw rod 13 to rotate backward, since right piston 15 can only axis
To movement, thus, right end screw rod 13 pushes right piston 15 to move right, and then, right piston 15 pushes left brake pad 16 to move right
It is dynamic；Constantly increase with the driving current intensity of actuating motor 1, act on the braking moment in brake disc 18 in left brake pad
16 and right brake pad 17 under the action of constantly increase, brake disc 18 is gradually braked；When the driving current intensity of actuating motor 1 reaches
During to given threshold, brake disc 18 is braked completely, and the driving current intensity of actuating motor 1 is down to locking electricity by control unit 3
Intensity of flow threshold value is maintained the braking moment acted in brake disc 18.If tachogenerator 24 detects brake disc 18
It rotates, and during velocity of rotation arrival given threshold, the current strength of the increase driving actuating motor 1 of control unit 3, and then,
The clamping force acted on left brake pad 16 and right brake pad 17 is continuously increased, and the braking moment in brake disc 18 constantly increases,
After tachogenerator 24 detects that brake disc 18 is braked completely, control unit 3 is by the driving current intensity weight of actuating motor 1
Newly it is down to locking current intensity threshold.
Two separation-release
When brake disc 18 changes from on-position to release conditions, control unit 3 is performed by the driving of higher level's control command
Motor 1 rotates backward (definition is rotated backward as release direction), and actuating motor 1 is after deceleration unit 2 increases torque, by defeated
Shaft 5 drives input gear 4 to rotate backward, and input gear 4 drives output gear 11 to rotate forward, and output gear 11 drives left end
Screw rod 12 rotates forward, since left piston 14 can only move axially, thus, left end screw rod 12 drives left piston 14 to move right,
And then the inside of the left side 31 of caliper frame 7 is left in 14 left side of left piston, caliper frame 7 is answered in caliper frame top guide bar sealing ring
Under the power effect of position, right side 14 is driven to move right, and then right brake pad 17 moves right, right brake pad 17 is right with brake disc 18
End face detaches；Meanwhile output gear 11 drives right end screw rod 13 to rotate forward, since right piston 15 can only move axially, thus,
Right end screw rod 13 drives right piston 15 to be moved to the left, and then, right piston 15 is detached with left brake pad 16, and left brake pad 16 is in each structure
The effect of part flexible deformation restoring force is lower to be detached with 18 left side of brake disc；Electricity is performed when control unit 3 is detected by code-disc 23
After the rotation setting revolution of machine 1, control unit 3 closes actuating motor 1, completes separation-release of brake disc 18；Separation-release work
During operation mode, control unit 3 controls actuating motor 1 to rotate backward setting revolution, can thus solve left brake pad 16 and the right side
Brake pad 17 solves braking every time and performs the response time inconsistent to ask because abrasion causes increasing with 18 gap of brake disc
Topic.
The embodiment of the utility model is explained in detail, but the utility model is not limited to be retouched above in association with attached drawing
The embodiment stated.For a person skilled in the art, it is right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the scope of protection of the utility model.
