The movement of push rod 133 is oriented to, and can further increase the structural compactness of brake.
Parking deceleration mechanism 120 can be the deceleration mechanism of any suitable type, as long as can be by the defeated of parking motor 110
Torque reduction passes to parking screw rod 131 after increasing square out.In one embodiment, as shown in figure 4, parking deceleration mechanism
120 can bore difference planet speed-reducer structure for beat.
Fig. 5 is the structural schematic diagram that beat bores poor planetary reduction gear, mainly by rotating bevel gear 1, beat bevel gear 2, defeated
Enter the compositions such as beat generator H and the circumferential limitation pair on axis 5.Wherein beat generator H has drift angle by the end of input shaft 5
The spindle nose 6 and tapered roller bearing 7 of Σ is constituted.Bevel gear 2 is equivalent to an internal bevel gear, with the cone tooth on output shaft 9
1 composition internal messing of wheel, one end of beat bevel gear 2 is on the tapered roller bearing 7 at drift angle spindle nose 6, other end spherical surface
Bearing 8 is connect with the shaft end of output shaft 9 composition flexural pivot.The vertex of a cone of two bevel gears is overlapped with the center O point of spherical bearing, in beat
The outer rim of bevel gear 2 is equipped with cydariform outer gear ring 3, circumferentially limits pair with 4 groups of ring gear.
Beat bores the transmission principle of poor planetary reduction gear are as follows: when input shaft 5 drives drift angle spindle nose 6 around the fixing axle of input shaft
When line nn is rotated, the axes O O of drift angle spindle noseHJust forming a cone-apex angle is 2 Σ cone-beam spaces.Due on drift angle spindle nose 6
The constraint secondary by circumferential limitation of beat bevel gear 2, turnover movement cannot be done, this cone-beam movement of drift angle spindle nose just forces
Beat bevel gear 2 makees circulation beat movement around O point, forms engaging for circulation folding with the rotating bevel gear 1 on output shaft 9
State.In shown position, two bevel gears top is in full meshing state, and forms full disengaged condition in lower part.But when drift angle turns over
180 ° to position A ' when, two bevel gears lower part is in full meshing state, and top is in full disengaged condition.When drift angle spindle nose turns over again
180 ° when being returned to original position, are exactly completed a beat engagement circulation.The process that spindle nose is rotated around fixed axis nn in drift angle
In, the gear teeth of beat bevel gear are along the circumferential direction recycled into and exit engagement, make region of engagement along the pitch cone of output bevel gear wheel
Transfer.
In the case where boring poor planetary reduction gear using beat, the motor shaft 111 of parking motor 110 with can be bored with beat it is poor
The input shaft 5 of planetary reduction gear is connected, and the output shaft 9 that beat bores poor planetary reduction gear can be connected with cam 131.
In another embodiment, as shown in figure 3, parking deceleration mechanism 120 can be the second planet-gear speed reducer
Structure, second planetary gear reducing mechanism include the second sun gear 121, the second planetary gear 122, the second planet carrier 123 and second
Gear ring 124, wherein the second sun gear 121 is connect with the motor shaft 111 of parking motor 110, the second planet carrier 123 and parking silk
Bar 131 connects, and the second gear ring 124 is fixed in braking clamp body 10.
After guaranteeing 110 power loss of parking motor, push rod 132 remains to be maintained at the position for realizing parking braking, in one kind
In embodiment, as shown in Fig. 3, Fig. 4 and Fig. 6, parking braking unit can also include electromagnetic clutch 80, electromagnetic clutch 80
It is mounted on the motor shaft 111 of parking motor 110, parking system is kept to the locking of motor shaft 111 by electromagnetic clutch 80
Dynamic state.
Specifically, when 80 power loss of electromagnetic clutch, electromagnetic clutch 80 is engaged with the motor shaft of locking parking motor 110
111, so that cam 131 is not able to rotate, so that push rod 132 is made to be maintained at the position for realizing parking braking, it is immovable, and then make
Push rod 132 keeps the thrust to the first brake block 31, keeps parking braking state.When electromagnetic clutch 80 it is electric when, electromagnetism from
Clutch 80 is separated to discharge motor shaft 111.
Optionally, electromagnetic clutch 80 may include clutch housing 81, electromagnet, translational friction piece 85, spin friction
Piece 86, outer race 87 and inside race 88.Wherein, clutch housing 81 is fixed relative to braking clamp body 10, and electromagnet may include
Fixed core 82, dynamic iron core 83 and the driving spring 84 for acting on dynamic iron core 83.Inside race 88 and motor shaft 111 pass through spline slide
Connection, rotary friction pad 86 are arranged on inside race 88 can rotate under the drive of motor shaft 41.Outer race 87 and clutch
The inner wall of device shell 81 is connected by spline slide, and translational friction piece 85 is arranged on outer race 87 with can be along motor shaft 111
Axial translation.Fixed core 82 and dynamic iron core 83 can be formed as cyclic structure, and dynamic iron core 83 is set in motor shaft 111
Outside, fixed core 82 are set in the outside of dynamic iron core 83, so that the more compact structure of brake, axial dimension are smaller.Work as electromagnetism
When iron power loss, magnetic attraction between fixed core 82 and dynamic iron core 83 disappears, dynamic iron core 83 under the action of driving spring 84 to the right
It is mobile, and translational friction piece 85 and rotary friction pad 86 is pushed to engage, frictional force between the two embraces motor shaft 111
Extremely；When electromagnet obtains it is electric when, generate magnetic attraction between fixed core 82 and dynamic iron core 83 so that dynamic iron core 83 reset while compress
Driving spring 84, translational friction piece 85 and rotary friction pad 86 separate, and frictional force between the two disappears to release to motor
The locking of axis 111.
When needing to be implemented parking braking function in driving conditions, parking motor 110 must be electric, and passes sequentially through parking speed reducer
Structure 120 and 131 driving push rod 132 of cam are mobile, and push rod 132 pushes brake block to clamp brake disc 20, (example when reaching parking requirement
Such as, parking brake force reaches target braking force, and parking brake force increases to the time used in target braking force less than pre- from zero
If the time), 110 power loss of parking motor, the work of electromagnetic clutch 80 keeps parking with the motor shaft 111 of locking parking motor 110
Brake force executes parking braking function.When releasing parking braking, electromagnetic clutch 80 loses locking power, discharges motor shaft 111.
In order to keep brake structural more compact, electromagnetic clutch 80 can be integrated in inside parking motor 110.
In one embodiment, parking motor 110, electromagnetic clutch 80, parking deceleration mechanism 120, crank connecting link machine
Structure 130 can be set in same housing 140, which for example can be fixed on one by fastener with braking clamp body 10
It rises.Clutch housing 81 can be fixed in shell 140.
It is described in detail below in conjunction with attached drawing former according to the work of the disk brake of an embodiment of the present disclosure
Reason.
When service brake, parking motor 110 does not work, and the rotor 42 of traveling motor 40 is driven by braking action of vehicle mechanism 50
Screw rod 61 rotates, so that the nut 62 being sleeved on driving screw rod 61 moves right, so that brake block is pushed to clamp brake disc 20,
The moment of friction for preventing vehicle wheel rotation is generated, realizes service brake.
When parking braking, traveling motor 40 does not work, and parking motor 110 passes sequentially through parking deceleration mechanism 120, slide crank
Block mechanism 130 and force-increasing mechanism driving push rod 133 are mobile, and push rod 133 pushes brake block to clamp brake disc 20, reach parking requirement
When, 110 power loss of parking motor, 80 power loss of electromagnetic clutch keeps parking braking with the motor shaft 111 of locking parking motor 110
Power realizes parking braking.When needing to release parking braking, electromagnetic clutch 80 obtains the electric motor shaft to discharge parking motor 110
111, parking brake force disappears.
