The invention relates to a device brake caliper rail vehicle according to the restrictive part of paragraph 1 of the claims.

The device of the brake caliper is known from DE 4431353 C1. In the device of the brake caliper brake of a rail vehicle is provided by a known bearing system, which contains at least two levers of the brake caliper, which are aimed at each other in the direction of the external surfaces of the body, each of which is provided eccentrically in motion one located on the end side of the eccentric crank shaft. The arms of the caliper node brake caliper mounted on the cranks rotatably. Further, the levers caliper axis is connected with the cranks of the eccentric shaft.

In the known system bearing the annular flange of the caliper arm is mounted for sliding on the rotating together with the drive shaft of the cover disc, which again with axial bearing mounted along the axis relative to the housing. However, in both systems the axial bearing arise relatively high friction losses. As the axial bearing at the side of the case is, when viewed in the axial direction of the eccentric shaft, in the field, characterized b the more the diameter of the main part of the eccentric shaft. But because of this, the effective friction diameter loaded axial forces and therefore creating friction torque of the axial bearing is relatively high, so that the axial bearing creates undesirable high moment of friction forces, which in turn reduces the efficiency of the drive transmission containing such eccentric mechanism.

In such devices the brake caliper has a problem, namely that of the oscillations, which are levers brake caliper while driving rail vehicles in unused and therefore not the clamped condition of the brakes, lead to excessively loud air noise.

In EP 0732247 A2 also describes a node of the disk brake of a rail vehicle in a device of the brake caliper with eccentrically mounted levers caliper. Levers caliper brake caliper through the thrust sliding rings rely on the eccentric cranks of the shaft.

In this regard, the present invention is to improve devices of the brake caliper rail vehicles mentioned the reduction of friction losses.

In accordance with the invention this task is solved by technical solutions, characterized by signs of paragraph 1 fo the mules of the invention.

According to the invention the axial bearing, when viewed in the axial direction of the eccentric shaft is located in the area between the crank lever of the brake caliper and the housing or fixed to the body part and the axial power flow from the brake lever caliper is directed straight in the axial bearing and thence into the housing or fixed to the body part.

As in this case, the axial bearing can have a smaller diameter than in the prior art, the result is less effective lever arm for acting in the axial bearing friction torque, so that the latter becomes smaller than in the cited prior art. In the implemented high efficiency system bearing supports.

Preferred embodiments of the present invention are characterized in the dependent claims.

Particularly preferably, the axial bearing is located directly between the element and the housing or a part fixed to the body. In this case, the axial power flow from the item goes directly into the axial bearing and thence into the body or the part attached to the housing. Thus, the result is a shorter, direct power flow between the element and the housing, without intermediate switching on the eccentric shaft, resulting in less elastic RA is Yami and therefore mostly hard power transmission. Node brake caliper this leads to is definitely educated pressure points and points braking brakes.

The present invention is illustrated by drawings, which presents the following:

figure 1 is a perspective view of the device of the brake caliper with sealing systems according to a preferred variant implementation of the invention;

figure 2 is a cross section of the seal systems of figure 1 on an enlarged scale;

figure 3 is a cross section of the gasket system according to another variant implementation of the invention.

Figure 1 shows the device 2 brake caliper brake of a rail vehicle, which is not shown interacts with the brake disc. The device 2 of the brake caliper 1 is shown in its working position, i.e. above structural elements are also installed at the top.

The device 2 brake caliper is driven not described here in more detail by the Executive body 3 has an impact on the eccentric shaft 4 located on the end sides of the cranks, the upper crank 6 and the lower crank 8, which, speaking of the holes 10, 12 of the housing 14 of the device 2 brake caliper mounted for rotation respectively in each arm of the brake caliper, the upper arm 16 of the brake caliper and lower the lever 18 that is masnago caliper. Shown in figure 1 the working position of the device 2 brake caliper is basically horizontally, so that, when viewed in the direction of gravity, the upper arm 16 of the brake caliper is located at a higher level than the lower arm 18 of the brake caliper.

During the rotation of the eccentric shaft 4, the levers 16, 18 of the brake caliper are moving in the direction of the brake disc, resulting located on the levers 16, 18 brake caliper holders 22, 24 of the brake linings with the brake pads come with a disk in frictional contact. The ends of the levers 16, 18 brake caliper directed from the holders 22, 24 of brake pads, installed rotatably around the rotary axis 20 parallel to the Z-axis at the ends of the disk 21 to the push rod, the position of which can be rearranged to adjust the wear. When the elongation of the disk 21 to the push rod in the Y-direction ends of the levers 16, 18 of the brake caliper away from each other, so that they curl around the cranks 6, 8 eccentric shaft 4, to reduce the distance holders 22, 24 plates from each other.

As clearly shown in figure 2, the lower arm 18 of the brake caliper, which it describes as a substitute of the upper arm 16 of the brake caliper has to end side of the blind hole 26, which set the Jena sleeve 28, the inner radial surface of the perimeter which forms the liner outer radial needle bearing 30, with which the crank 8 is mounted for rotation relative to the arm 18 of the brake caliper. For this purpose, the crank 8 is enclosed in the sleeve 32, which forms another liner outer radial needle bearing 30. On the other side of the Central section 34 of the eccentric shaft 4 is mounted for rotation relative to the housing 14 by means of two internal radial needle roller bearings 36. Such a bearing system can be adjusted by a specialist to the respective requirements, for example it can be made in the form of a system of bearings.

When not engaged the brake levers 16, 18 of the caliper carry out rotational motion relative to the cranks 6, 8, while the rail vehicles with disc brakes in the framework of the so-called sinusoidal course there are movements across the axis, which can also be disc brakes linked with the axes. When the brake disc is in contact with the brake pad and consequently rejects the lever 16, 18 of the brake caliper, the latter carries out a rotational movement around a freely rotating in this mode of operation of the cranks 6, 8.

When the second brake, i.e. when rotating the eccentric drive shaft 4, the Central axis 38 of the crank 8 is doing as translational movement in the direction of X-axis and Y-axis, and rotation around the Central axis 40 of the eccentric shaft, which is parallel to the Z-axis or vertical direction. Such eccentric trajectory can realize the lever 18 brake caliper mounted on it using an external radial needle bearing 30, in order to ensure the movement of the clamp or release the holders 22, 24 of the brake lining relative to the brake disc. Exact description thereof eccentric drive contained in the said document DE 102005049058 A1, so there is no need for it to stop.

On the end surface 42 of the opening 12 of the housing has a flange 44 with a mounting surface 48, performed on the ledge 46 of the flange, centering edge protrusion 50 enters the opening in the housing 12 and is held there, mostly with press fit. Thus, the flange 44 forms a fixed to the body part. The radial outer surface of the perimeter flange 44 provided with a radially inward projecting recess 52. Further, the end surface 54 of the flange 44 that is directed from the housing 14 forms a bearing surface for axial sliding bearing 56.

Axial thrust ring 56 is site is preferably of damping material for sliding bearings with low E-module, for example polyamide or bearing bronze. Due to this, preferably damped oscillations, which are generated by the levers 16, 18 of the brake caliper in unused and therefore not tensioned. Again, this also contributes to reducing the noise level.

Axial thrust ring 56 is fixed preferably on the front side 58 of the lever 18 brake caliper, looking at the case 14, largely by means not shown on the image of the cross section in figure 2 screw connection. Attached to the lever of the brake caliper axial thrust ring 56 with the intended surface of the sliding bearing, which is formed here by face 54 is installed on the housing flange 44 forms the axial sliding bearing for the lever 18 of the brake caliper relative to the housing 14.

As can easily be illustrated with figure 1, there are axial and shear forces, i.e. forces directed towards the Central axis 40 of the eccentric shaft or in the Z-direction, when engaged brake brake lining pressed against the brake disk, and because of this there are friction forces that impinge on the levers 16, 18 brake caliper mounted to the end side on the disk 21 to the push rod, perpendicular to their length in the form of a bending load. This bending is downloading causes lateral or axial forces, which in the present case, the perceived axial thrust ring 56 on the housing 14.

What is essential is that the power flow transverse or axial forces directed in the Z-direction from the arms 16, 18 of the brake caliper directly at the target axial thrust ring 56 and thence to the fixed to the body flanges 44 and finally to the housing 14, not sucking in this power flow eccentric shaft 4 or the cranks 6, 8. In contrast, the lateral forces caused by movement of the pulling force on the levers 16, 18 of the brake caliper and acting in the X-Y plane through the outer radial needle bearing 30 are transmitted to the eccentric shaft 4, which, again, through the inner radial needle bearings 36 rests on the housing 14.

Since the unit 2 brake caliper on a track vehicle is in the area, experiencing the effects of dirty water and spray, the eccentric shaft 4 or the cranks 6, 8 on the terminal side needs to be compacted relative to the housing 14.

Figure 2 shows in detail the upper sealing system 60 and the lower sealing system 62 device 2 brake caliper. Below is described the same structure as the lower system 62 seals, as it is a replacement for the upper system 60 seals.

Lower system 62 includes seals airtight seal that way is by using, at least one fixed on one side on the housing 14 and with the other hand on the lower arm 18 of the brake caliper of at least partially elastic bellows 64. When the bellows 64 is designed so that it can follow the radial movements of the crank 8 relative to the housing 14 defined by the eccentric drive in the X-Y plane perpendicular to the Central axis 40 of the eccentric shaft 4, and the folds of the bellows 64 compensate for these movements.

Preferably the bellows 64 at least partially made of rubber, mainly completely NBR-rubber (Acrylonitrile-butadiene-rubber), and the ends 66, 68 of the bellows 64 is connected to the housing 14 and the lever of the brake caliper with geometric and/or frictional closure.

The bellows 64 radially covers the flange 44 and has, when viewed in the direction of the Central axis 40 of the eccentric shaft 4 (Z-direction)around its longitudinal length. At least some of the folds of the bellows 64 come into the radial recess 52 of the flange 44, which is connected to the housing 14.

Particularly preferably, the end 66 of the bellows 64, attached to the lever 18 of the brake caliper, is connected in contrast, mainly all the way through the rigid ring 70, which is preferably mounted on the lever 18 of the brake caliper with what omashu geometric circuit. This permanent connection is made, for example, by using the fact that the ring 70 at least partially cured in the bellows 64. This ring 70 and the axial thrust ring 56 is preferably secured to the end surface 58 of the lever 18 brake caliper, aimed at housing 14, with at least one screw 72. Further, the ring 70 comprises an axial thrust ring 56.

On the other hand, the end 68 of the bellows 64, attached to the housing 14, is clamped between the end surface 48 of the flange 44 and the end surface 42 of the housing 14 is directed towards the lever 18 of the brake caliper, using power and/or geometric circuit, to which the end 68 may be increased 74 cross-section, which is placed in a corresponding annular recess in the end surface 48 of the flange 44.

In another embodiment according to figure 3 remaining the same is equally applicable, as in the previous embodiment, the elements denoted by the same positions. In contrast, the end 68 of the bellows 64, attached to the flange 44 or housing 14, preferably clamped using a geometric circuit between the end surface 75 of the flange 44, directed from the end surface 48, and a separate clamping ring 76, which is connected with the flange 44 with screws. Further, the ring 70 mounted on the other end 66 of the bellows 64 by means of vulcanization, has a shelf 78 with L-shaped cross-section 78, which is covered and due to this fixed axial thrust ring 56 mounted on the end surface 58 of the lever 18 of the brake caliper with screws 80. In the rest of the system 60, 62 seals, and install the eccentric shaft 4 and the levers 16, 18 brake caliper is made identical to a variant of execution according to figure 2.

Application systems 60, 62 seals are not limited to devices 2 brake caliper. On the contrary, such systems 60, 62 seals can be used between any body 14 has mounted on the bearings of the eccentric shaft and protruding from the housing 14 with the end side of the crank 6, 8 eccentric shaft 4.
