The schematic diagram of Fig. 1 break of the present invention is bearing on one or more pillars that stretch out from an additional wall or an electric machine casing its axial restraint and becomes U-shaped ground to surround disk to be braked as a whole.
The sectional drawing that the break that Figure 1A is identical intercepts along Fig. 1 center line C-C;
Another form of implementation of Fig. 2 break of the present invention is similar to the schematic diagram of Fig. 1 view, but here break axially movably is bearing on one/a plurality of pillars;
Fig. 3,3A, 4 and 5 are the schematic diagram of various possible form of implementation of the electromagnet structure of break of the present invention equally.
Embodiment
According to the form of implementation of Fig. 1 and 1A, the electromagnet 1 at center constitutes and makes it that armature disc 2,3 of outwards being pushed open by stage clip respectively be arranged in both sides.Armature disc 3 towards disk 5 to be braked is provided with a friction plate 4, borrows its armature disc 3 can be pressed onto on this disk 5.Break constitute generally make it with its electromagnet 1 axial restraint be bearing on one or more pillars 11 that from additional wall or electric machine casing 22, stretch out and become U-shaped ground to surround disk to be braked as a whole.
Away from the armature disc 2 of disk 5 to be braked constitute make its via one in the footpath friction flange plate 23 back sides of radially extending to the outside and that axially extended fishplate bar 21 and is connected thereon rabbet disk 5 to be braked and can be pressed onto on the disk to be braked 5 with a friction plate 6 thus.Guarantee to make when electromagnet 1 galvanization friction plate 4 and 6 to back out and the latter can rotate freely the sliding wear that does not have interference by the structure of this U-shaped from disk to be braked 5.When electromagnet stops stage clip 7 and 8 or 20 power via armature disc 2 and 3 and friction plate 4 and 6 pass on the disk to be braked 5, thereby produce the frictional force of a braking.
Second form of implementation by Fig. 2 is equally operated with first form of implementation on principle, but also carries out some technical replenishing, and this improves the centering of break to disk to be braked under the situation that axially movably is bearing in the electromagnet on the pillar 11.
Therefore electromagnet 1 axially movably is bearing on the pillar 11 in this form of implementation, the for example elastic element 24 as being made of plastics of annular that is provided with one heart in addition is placed between electromagnet 1 and two armature discs 2 and 3, it guarantees that the air gap 25 and 26 between electromagnet 1 and two armature discs 2 and 3 is roughly the same all the time.The axial position that can compensate disk 5 to be braked thus changes (for example because the load change of lift) and it is guaranteed, break is when throwing off that is getting loose, no sliding wear ground discharges disk 5 to be braked, and very big air gap 9 and 10 needn't be set at the brake strip place.The little air gap 9 and 10 in brake strip place helps weakening the manipulation noise of break.
If when electromagnet stops, only discharge an armature disc, for example armature disc 3, then it discharges up to friction plate 4 is bearing on the disk to be braked 5 always, and whole electromagnet 1 is moved up to making friction plate 6 also be adjacent to disk to be braked 5 with armature disc 2.By the such structure of break in this case friction plate 4 and 6 and disk 5 to be braked between produce impacting force completely equally.Therefore produce braking moment completely.Whole requirements of the two-way when this scheme satisfies emergency braking are even simultaneously have only a brake circuit that works also to produce identical braking moment completely in two complete brake circuits.
On the contrary, each elastic element 24 constitutes and makes it apply the less power of pushing open in the break that is released that is brakes between armature disc 2,3 and electromagnet 1, its rigidity compare with stage clip 7,8 or 20 be specified to so big, make that when two air gaps 25 and 26 have a difference electromagnet 1 being produced one makes a concerted effort, it makes electromagnet 1 mobile like this when the electromagnetic ground disengage brake, that is, to make two air gaps 25 and 26 be balanced mutually to a great extent and break thus once more to disk 5 centering.
This invention scheme of two above-mentioned forms of implementation is because electromagnet 1 fixedly provides two kinds of possibilities at pillar 11.Or it is securely fixed in a position, promptly be fixedly connected on pillar 11, or its axis that is parallel to disk to be braked is bearing on the pillar 11 movably.
The CONSTRUCTED SPECIFICATION fixing or that movably support of the not shown electromagnet of each principle on pillar 11 at accompanying drawing.This can consider or simple sliding bearing or a simple clamp device or a commeasurable device.
The advantage that fixedly installs of electromagnet is that generally two brake strips are unclamped and can not treat the sliding wear of brake from disk.
Under the situation of the removable setting of electromagnet 1, obtain a two-way break in an advantageous manner, but after break is thrown off, for example because vibration can not be got rid of sliding wear fully.
If electromagnet 1 is fixedly mounted on the pillar 11, then the position of electromagnet 1 is aligned to the axial position of disk 5 to be braked, and it is guaranteed, when break is thrown off, form enough big air gap 9 and 10 in the both sides of disk 5 to be braked, and disk this under the situation of oscillating motion not to friction plate 4 and 6 sliding wears.
If on the other hand electromagnet is installed on the pillar movably, then constitute a caliper brake, it is sliding wear and have the braking system of a redundancy not, so that still apply the torque of a braking when an armature disc blocks.May owing to break on pillar unexpected motion or the axial motion of disk sliding wear takes place.
Structure about electromagnet 1 can be imagined some forms of implementation according to Fig. 3,3A, 4 and 5.
By Fig. 3 and 3A electromagnet 1 back-to-back by in the middle of one be connected fishplate bar 12 and two electromagnetic coils 13 and 14 constitute.
The interior utmost point and the outer utmost point by Fig. 4 electromagnet 1 interconnect via a fishplate bar 15 in the side.This fishplate bar is made by nonmagnetic substance, wherein is provided with an electromagnetic coil 16.
Separate to each other by the utmost point in Fig. 5 17 and the outer utmost point 19, the wherein interior utmost point 17 is fixed on one of two armature discs 2,3 and electromagnetic coil 18 is connected in the interior utmost point 17 or the outer utmost point 19.
