INSPECTED

Drive lever that raits one of the brake pads over a Cam surface cooperates, and a transmission part that said lever is articulated and that can be moved relative to the disc to that of the drive lever to be able to transfer the braking effect exerted to the second brake pad.

It also relates preferably, but not exclusively, to those brakes in which the transmission part inter alia, is mounted so that it can pivot or tilt against resilient means relative to the fixed holder, wherein the tilt axis of the transmission part runs in a practically parallel to a diameter of the disk or wherein this tilting axis in a direction practically parallel to a chord of the disk near the edge of the disk lies »but this pivot axis and the tilt axis of the drive lever on the transmission part in each case are parallel to each other.

When a train is exerted on the drive lever, it pivots on the transmission part and, on the one hand, exerts an effect on the brake pad, on which it rests with its cam surface, in one direction so that this brake pad rests against the disc, and on the other hand pushes it in the opposite direction Direction of the transmission part to which it is hinged back, so that this part has a corresponding effect on the other brake pad and the said disc is clamped between the two brake pads and thereby braked.

In most cases, the drive lever is a resilient one Associated device, and this pushes the drive lever back into a rest position in which a stop part of said Drive lever against a stop part of the transmission

partly lays.

In the usual embodiment of this type, the is available Drive lever associated resilient return device wholly or partially with the transmission part aaf its outside in contact.

It follows that on the one hand frictional forces occur between this spring and the transmission part during operation, which have a detrimental effect on the life of the spring and the efficiency of the overall arrangement and that on the other hand, the spring, because it is on the outside, gradually becomes dirty, which impairs its effect will.

The invention is primarily based on the object of developing an arrangement in which these disadvantages do not occur appear.

The invention therefore relates, more precisely, to a disc brake of the type described above and is characterized in that that the drive lever of the disc brake two each other has oppositely arranged wings, which at at least one of their ends by a U-shaped connecting arc are interconnected that said drive lever is articulated with one of its wings on the associated transmission part is attached that the return device assigned to it is designed as a compression spring between the transmission part and the other of its wings is stretched out on the inside and which is practical in its rest position runs perpendicular to the pivot axis of the drive lever, and that, at least in this rest position, the axis of the said compression spring is at a distance from said pivot axis.

The compression spring because of its eccentric arrangement

509882/0380

with respect to the pivot axis of the drive lever in this causes a return torque that brings him to his rest, position, is preferably supported on the bottom of a blind hole that is cut into the transmission part, and at least in the vicinity of the opening of the blind hole, its side walls are widened outwards, for example by they open conically.

Therefore advantageously occurs between the compression spring and the transmission part during the rotary movements of the drive lever on the transmission part no friction between the spring and the transmission part.

In addition, the rigidity of the Drive lever enlarged.

According to a further development of this as an improvement of the Protection of the return spring for the drive lever and its rotational movement advantageous construction are both ends the wing of this drive lever are brought together by an O-shaped connecting bow.

The space of the drive lever in which the return spring for the drive lever and its pivot axis are located thus completely completed by the drive lever itself.

The rigidity of the drive lever is further increased by this construction.

Since this construction in turn represents a particularly interesting solution, the invention is also concerned with regard to it on the second embodiment a mechanically operated Disc brake, which has a disc rotatably connected to the organ to be braked, a fixed

509882/0380

standing holder, two of the fixed holder on Brake pads carried on one side of the disk and displaceable perpendicular to the plane of the disk, one Drive lever that interacts with one of the brake pads via a cam surface, and a transmission part, to which said lever is articulated and which can be moved relative to the disk in order to apply the braking effect exerted by the drive lever to the second brake pad to be able to transmit, and this disc brake is characterized in that, regardless of the presence or the lack of a return device associated with the drive lever, the drive lever two opposite each other has arranged wings, the two ends of which are brought together by an O-shaped connecting bend are, and that the wings of said drive lever, the pivot bearing of the drive lever on the transmission part enclose.

Thanks to this O-shaped design of the drive lever is it is possible according to a further development of the invention, the Drive lever to be provided with a protective cap that protects the feedback spring provided for the drive lever and further improve the protection of its pivoting lap.

Since it is in the practical implementation of the transmission part is a U-shaped bracket, the arms of which are practically radially on both sides of the disc and the stationary Holder are arranged, the drive lever engages one of the arms of said bracket, and a protective cap is attached to said arm on at least one side of the drive lever, such a protective cap preferably is provided on both sides of the drive lever.

509882/0380

The return spring provided, for example, on the drive lever and the pivot bearing of the drive lever are in this case advantageously inside a completely closed space.

If the drive lever, as explained above, is U-shaped or O-shaped, the pivot bearing of the Drive lever on the transmission part in known per se Way be equipped with a swivel edge, which is formed on the drive lever or the transmission part can be and is received in a pivot groove that is executed in the other of the two organs, wherein a resilient pressing device is provided, which said pivot groove with the cooperating with it Keeps swivel edge in contact.

In this case, because of the special arrangement of the compression spring, that according to the invention becomes that of the drive lever Associated resilient return device forms the resilient device, which the pivot groove with the pivot edge in Keeps contact, in turn formed by this resilient return device.

The spring according to the invention lies between one of the wings of the drive lever and the transmission part and therefore presses the other wing of the drive lever in the direction of said transmission part because the drive lever lies against the transmission part.

It is also customary for the stationary holder in such a disc brake to have two parallel brackets To provide flanges, each standing on one side of the disk, and the fixed holder is by bending an initially flat blank made in a U-shape.

509882/0380

Preferably, according to the invention, this blank has a trapezoidal shape and becomes around one parallel to its bases Axis bent so that one flange of the fixed holder obtained in this way is longer than at its free end the other flange at the corresponding free end.

If you give a trapezoidal shape to such a blank, you can by punching blanks in overturned Limit the amount of metal waste inevitably remaining at the end of the punching process from a certain sheet metal, only a minimum amount of material being used for each holder made from such a blank that is sufficient for the rigidity of the holder and its strength.

crimped right to the slot 35 of the transmission member; the opening 4 3 intersects the slot 35.

It can be seen that the axis of the opening 4 3 and thus the axis of the pin 4 2 distance from that through the central zone of the central section 21 of the transmission 1a. 19 running diameter plane the disc 10 has.

The inner cut surface of the wing 37 of the drive lever 36 also forms a shoulder 44 which acts as a stop for the base 45 of the slot 35 of the transmission part 19 is to work in relation to the rest position of the drive lever 36 to define the transmission part.

With the outer cut surface of his wing 37 lies the Drive lever 36 on brake pad 14a and to this extent this outer cut surface forms a cam surface 46.

The end of the other wing 38 of the drive lever 36 forms a hook 47 on which a pull rope (not shown) can be attached.

Between the inner cut surface of this wing 38 and the arm 22A of the transmission part 19 is a resilient return device arranged, which is intended to push the drive lever 36 in the direction of its rest position, which is defined in more detail above became.

This resilient return device has a compression spring 50, which is practical in its rest position shown in FIG perpendicular to the pivot 4 2 of the drive lever 36 on the transmission part 19 and which is practically in the through the middle zone of the middle section 21 of the transmission

• Λ.

partly 19 extending Durchiressereplane of the disc 10 is located.

It follows that the axis of the spring 50 at least - in this rest position is at a distance from the axis of rotation of the drive lever 36.

In the example shown, the spring 5 0 is supported on the beden of a blind hole 5 2, which is in the arm 22A of the ■ Transmission part 19 is cut, and at least in the vicinity of its mouth to the outside, the side wall widens of the blind hole 5 2 to the outside, for example in the manner shown, after which this wall extends in the axial direction opens conically from the inside to the outside.

At the same time, the spring 50, which forms the resilient return device for the drive lever, is supported in the present example is designed as a flat component, on the bottom of a notch 54, which is on the inner cut surface of the outer wing 38 of this drive lever is cut out, with the spring in a cup-shaped holder 55 rests, which is laterally provided with extensions 5 6, which bear against the cut surface and on the two side surfaces of the drive lever 36 rest.

The arm 22B of the transmission part 19 has, parallel to the axis of the disk 10, a pin 60, the preferably rounded end 61 of which ^{touches the brake pad I 1} IB.

So that the pin 60 can be adjusted, it is preferably, as also drawn, provided with a thread that is screwed into an internally threaded passage 6 2 of the arm 223 of the transmission member 19; is used to set a lock nut 54 screwed onto the pin 60.

- 13 -

509882/0380

In the example shown, the lock nut 64 and the free end of the threaded pin 60 are protected below a protective cap 65.

In the example shown, the brake pads have between on the one hand the points of contact of drive levers 36 or pins 60 which are carried by the transmission part 19 are, and associated brake pads 14A, 14B and on the other hand the tangential closest to the edge of the disc 10 Edge of said brake pads each have a retaining lug 66A, 66B, under which the drive lever 36 or the Pin 60 engages.

In the example shown, particularly recognizable in FIGS. 1 and 7, such a retaining lug 6 6A is, for example by a local bulge of the plate carrying the friction lining of the brake pad 14A and a local one Incision made in the plate.

Since the compression spring 50 is eccentric with respect to the pivot 4 2 of the drive lever 36, at least in its rest position, results from the force that the spring exerts on the drive lever exerts »a torque that seeks to pivot the drive lever in the direction of its rest position, which by the Stop of its shoulder 44 on the base 45 of the slot 35 of the transmission part 19 is defined.

Since this compression spring 50 is also supported on one side of the arm 22A of the transmission part 19, the side opposite, from which the pin protrudes, on which the drive lever pivot relative to the transmission part 19 can, this compression spring 50 forms a resilient device with which the pivot groove 40 this Drive lever 36 can be kept in contact with the pivoting edge, which the said pin 42 also represents.

609882/0380

Arm 22A of the transmission part 19 and practically around this Arm placed around two protective caps.

One of those protective caps made from a simple mug S8 made of metal, a synthetic plastic or a Another material is on the lower side of the drive lever 36 on the side of the free end of the arm 22A of the transmission part 19 is set.

The other cap on the other side of the drive lever 36 consists of an annular membrane 6 9 made of elastic Material which surrounds the arm 2 2A of the transmission part 19 and which engages in an annular groove 7 0 which is attached to the drive lever 36.

The mode of operation of this brake is identical in all respects to the mode of operation of the brake described above.

One sees oa% retaining tabs 66A, 66B of the brake pads 14A, 14B in any case allow the holding of the transmission part 19 and the various positively connected with him organs when the spring 28 should break unfortunately.

Of course, the invention is not limited to those shown and described embodiments, but includes all Design variants and / or combinations of the various elements of the invention.

In particular, the invention can also be used in mechanically operated disc brakes in which the axis of rotation of the transmission part not practically parallel to a diameter direction of the disk, but parallel to one direction which runs parallel to a chord of the disk which runs near the edge of the disk.

a 181

When the cable attached to the drive lever 36 is pulled in the direction of arrow F (FIG. 2), it rotates the drive lever around the pin 42 and prints the spring 50 together.

In a first phase, the drive lever 36 slides with it Cam surface 46 along the brake pad 14A and exerts such a pressure on it that it contacts the disc 10,

At the same time, the corresponding force is transmitted from the transmission piece 19 and the threaded bolt 60, which is located on the transmission part 19, to the brake pad IHB, which also contacts the disk 10.

During this first phase, the brake pads 14A, 14B only touch the disc 10, and the amount of the corresponding Approach is more or less insignificant depending on the degree of wear of the friction linings of the brake pads.

In a second phase, the pulling force still exerted on the pulling cable attached to the drive lever 36 then rolls this drive lever without sliding with its cam surface 4 6 over the brake pad 14A and presses the Brake pad forcefully against the disc 10, the force, as before, through the transmission part 19 and the threaded bolt 60 is transferred to the brake pad 14B, which is thus also pressed forcefully against the disc 10.

The disk 10 is thus clamped and therefore braked.

When the train on the rope attached to the drive lever 36 subsides, the drive lever 36 is simultaneously returned to the rest position by the stretching spring 50.

During the second phase described above, which is carried out by

509882/0380

expresses a sliding-free rolling of the drive lever 36 on the brake pad WB, the transmission part 19 is due to the pulling action exerted on the part by the drive lever '36 is transmitted, in turn, forced to rotate around a momentary axis of rotation that is parallel to the axis of rotation of the drive lever 36 on this transmission part and which therefore, in the example described, runs parallel to a diameter direction of the disk 10.

The rotary or tilting movement of the transmission part 19 takes place against the force of the spring 28, which returns the transmission part to its rest position as soon as the pull exerted on the drive lever 36 ceases.

It can be seen that because of the special shape of the drive lever 36, the spring 50, which is used to return the drive lever, and the pivot 4 2, the drive lever 36 is assigned, are located in a space which is at least partially closed off by the drive lever 36.

According to a further development shown in FIGS In this construction, the two wings 37, 38 of the drive lever 36 are connected at their ends by a D-shaped connecting arc 39 connected to one another in such a way that the space in which the spring 50 and the pivot 4 2 are located is completely closed by the drive lever 36.

This 0-shaped shape of the drive lever 36 turns out to be also as suitable for the installation of caps, which again protect the spring 50 and the pivot 4 2 opposite any pollution.

In the embodiment shown in Figs. U to 6 are therefore to the rotary bearing of the drive jack 36 on the

Arm 22A of the transmission part 19 and practically υτ, put this arm around two protective caps.

One of those protective caps made from a simple mug 68 made of metal, a synthetic plastic or a other material is on the lower side of the drive lever 36 on the side of the free end of the arm 2 2A of the transmission part 19 is set.

The other cap on the other side of the drive lever 3G consists of an annular membrane 6S made of elastic Material surrounding the arm 22A of the transmission part 19 and which engages in an annular groove 70 which is attached to the drive lever 36.

The functioning of this brake is consistent in all respects corresponds to the mode of operation of the brake described above,

You can see that the retaining lugs 66A, 66B of the brake pads left + A, 1MB in each case holding the transmission part 19 and of the various organs positively connected to it should the spring 28 be unfortunate to break.

Of course, the innovation is not limited to the illustrated and described "embodiments, but includes all of them Design variants and / or combinations of the various Elements of innovation.

In particular, the innovation is also with mechanically operated Disc brakes applicable in which the axis of rotation of the transmission part not practically parallel to a diameter direction of the disc, but parallel to a lease is that running parallel to one near the disk ranch!
