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, parking screw body 130 and force-increasing mechanism driving push rod 150 are mobile, and push rod 150 pushes brake block to clamp brake disc 20,
(for example, parking brake force reaches target braking force, and parking brake force increases to target braking force from zero when reaching parking requirement
Time used is less than preset time), 110 power loss of parking motor, electromagnetic clutch 80 works with the electricity of locking parking motor 110
Arbor 111 keeps parking brake force, executes parking braking function.When releasing parking braking, electromagnetic clutch 80 loses locking
Power discharges motor shaft 111.
Using electromagnetic clutch 80, parking screw body 130 can arbitrarily select rolling lead screw mechanism or
Sliding screw mechanism.Specifically, parking screw body 130 can select planetary roller screw body or ball wire rod mechanism.It closes
It is already mentioned above in the advantages of planetary roller screw body and ball wire rod mechanism, details are not described herein.
After guaranteeing 110 power loss of parking motor, parking nut 132 remains to be maintained at the position for realizing parking braking,
In another embodiment, parking screw body 130 can be sliding screw mechanism, and the lead angle of parking screw rod 131
Less than Self-locking angle, so that parking screw body 130 has the function of unidirectional self-lock.In this case, when 110 power loss of parking motor
When, make parking nut 132 immovable by the self-locking function of parking screw body 130, stills remain in the parking system of realization
Dynamic position, thus push rod 150 still maintains the thrust to the first brake block 31, so that brake block keeps clamping brake disc 20.
In the disclosure, braking clamp body 10 can be integrally formed, and can also be formed by connecting by seperated molding multiple portions.
In embodiment shown in fig. 1, braking clamp body 10 is integrally formed.In the embodiment illustrated in figure 5, braking clamp body 10 includes
First part 101 and second part 102, first part 101 and second part 102 can for example be connected by fastener, and second
Brake block 32 is mounted in first part 101, traveling motor 40, braking action of vehicle mechanism 50, parking motor 110, parking speed reducer
Structure 120, lever mechanism 160 be arranged at the inside of second part 102, is provided in first part 101 and passes through for piston 90
Pilot hole, sealing ring 100 are arranged between piston 90 and the inner wall of the pilot hole.
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 of driving a vehicle rotates, so that the driving nut 62 being sleeved on driving screw rod 61 moves right, to push the first brake block
31 also move right and are pressed in brake disc 20, and then reaction force of the brake disc 20 to 62 1, nut of driving to the left, makes
Driving nut 62 is moved to the left together with braking clamp body 10 is whole, until the second brake block 32 also presses against in brake disc 20, at this moment
The brake block of two sides is all pressed in brake disc 20, to clamp brake disc 20, is generated the moment of friction for preventing vehicle wheel rotation, is realized
Service brake.
When parking braking, traveling motor 40 does not work, and parking motor 110 passes sequentially through parking deceleration mechanism 120, parking silk
Linkage 130 and force-increasing mechanism driving push rod 150 are mobile, and push rod 150 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.
According to another aspect of the present disclosure, a kind of vehicle is provided, which includes disk brake as described above.
The preferred embodiment of the disclosure is described in detail in conjunction with attached drawing above, still, the disclosure is not limited to above-mentioned reality
The detail in mode is applied, in the range of the technology design of the disclosure, a variety of letters can be carried out to the technical solution of the disclosure
Monotropic type, these simple variants belong to the protection scope of the disclosure.
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case where shield, can be combined in any appropriate way, in order to avoid unnecessary repetition, the disclosure to it is various can
No further explanation will be given for the combination of energy.
In addition, any combination can also be carried out between a variety of different embodiments of the disclosure, as long as it is without prejudice to originally
Disclosed thought equally should be considered as disclosure disclosure of that.
