专利摘要:
The invention consists of a protection that is mounted over disc brake units on trains to prevent the formation of sensitive areas on the outside of the brake unit. The protection is designed so that it encloses all sensitive parts of the brake unit but so that the brake arm closest to the brake disc passes through the protection so that these parts of the brake arms and lining holders and pads are outside the protection. The protection according to the invention consists of one or two fabric parts that are applied over the brake unit. The separate parts and ﬂ ikama are laid and folded so that they overlap each other and are locked with Velcro or similar (eg 3M dual lock) so that the cover can easily be opened completely or even dismantled when required for sewing or maintenance. The protection is further carried out with ﬂ ikar that act as doors for sewing and maintenance. The doors are closed with Velcro fastening. The arm for manually releasing the parking brake is pulled out through the cover or covered with such a hatch.

专利说明:

There are different designs of disc brake units with parking brake function but common is that they are applied by a spring, when the parking brake cylinder is activated with compressed air the spring is compressed and the brake is released and that, when the parking brake cylinder is not activated and the brake is applied, it can be released manually with a device which releases the spring.
There must be some play between the brake pads and the disc when the brake is not applied.
The controller's task is to reset (adjust) this game as the evidence wears. The adjustment takes place automatically with each brake application.
When changing the coating, the play between the coating holders and the disc is widened by turning a knob on the regulator, this to enable the installation of new coatings that are thicker than worn.
Winter time, in case of swirling snow due to loose snow cover or snowfall, icing occurs on the brake units, especially under weather conditions when the temperature is below freezing. The snow which then melts up at the contact with the hot brake disc during braking or in the wheel / rail contact during rollover and which sprays against the brake unit in the form of water or wet snow, freezes to ice when it hits the cold brake unit. Ice can also form on the brake unit after melting snow found on it, by dripping melted snow and ice in the vicinity of the brake unit due to heat from other heat sources such as the engines. Ice is also formed by wet snow in the event of snowfall hitting the brake unit and freezing to ice as the temperature drops.
Ice formation can quickly become extensive. O ﬁ a causes this problem, the ice prevents the movement of the regulator and brake arms, the brake control actuators are not able to break the ice. The most common consequence is that the brake cannot be released after the vehicle has come to a standstill or that the brake brakes when the train is rolling. By anti-theft braking is meant that the brake is inadvertently applied when the train is rolling. It has also happened that icing has caused damage to internal parts of the brake units due to forces that have arisen when the ice is pressed against a rubber bellows that covers these internal parts. Another consequence that has occurred is that the screws of the disc mounting brackets have been damaged due to overheating during anti-theft braking.
In other words, for some braking devices, such external icing is frequent and very problematic.
Today, there is no way or device to deal with this problem other than to defrost vehicles often mechanically or by melting the ice. But as icing often occurs very quickly, it is difficult to deal with the problem through de-icing, you simply can not de-icing often enough. Injection of glycol or similar in preventive sewing may reduce the problems, but it is doubtful whether this can always solve the problem.
Special part Problem solving The present invention solves the problem by fitting a cover with the features specified in the following claims over the entire or sensitive parts of the brake unit. The disadvantage of a guard is that access for inspection and maintenance of the brake unit is made more difficult. Especially manual release of the brake, which usually takes place outdoors, must be able to be performed easily and preferably without any further necessary measures than just that the brake is released manually by maneuvering the release lever ..
The protection according to the invention solves these problems in that it is easy to open for sewing and maintenance and also easy to reseal. The release lever for manual unloading is easy to reach by pulling it out through the cover so that opening / resealing is not required or by being easily accessible under a door that is easily resealed. The latter embodiment has the advantage that there is then no risk of ice accumulating on the outside of the cover at the release arm which makes unloading difficult.
The disadvantage is that the door must be opened during unloading and then resealed.
Another disadvantage of a protection is that it can be expensive and difficult to install due to of the complex geometry of the brake unit, which is illustrated in the accompanying figures where an example of a brake unit is shown.
The protection according to the invention solves these problems in that it is simple and cheap to manufacture and easy to assemble.
Another disadvantage of the cover is that if it is leaky and ice formation occurs inside the cover, the cover is made more difficult to defrost by this ice. The protection through the invention solves these problems by being tight so that icing does not occur inside the protection and, and this still happens for some reason, that the protection is easy to open completely or even to disassemble.
The cover is made of a cloth that is cut / cut in a suitable way to the right shape. The protection can of course also be designed in a slightly thicker material with double-curved surfaces that are adapted to the shape of the brake unit.
It consists of one or ﬂ your parts. The cover is inserted between the brake arms and tabs are pulled out through the openings in the brake arms. The cover is placed in place over the brake unit so that more or less the entire brake unit is covered. The parts of the protection and the ﬂ ices are re-plotted, i.e. with a certain overlap and must be attached during installation with Velcro or similar, eg 3M dual lid. The brake arms are thus led out through the protection, parts of these are thus outside the protection as well as mounting brackets and pads.
The doors for maintenance are made as ﬂ ikar which when opened is unfolded. The doors are also closed with Velcro or similar. In the example below, a tensioning belt is also used. It is made with a sperm so it can be easily opened and resealed. The Velcro straps are glued, welded or sewn onto the fabric.
Figure 1 shows a motor bogie for a train with two brake units without parking brake function (1) and two brake units with parking brake function (2). The brake discs (3) are mounted on either side of the wheels (4). The brake units are ib visibly suspended in the bogie frame at suspension points (12) and (13) so that they can follow the lateral movements of the wheels and thus the brake disc.
Figure 2 shows a brake unit with parking brake function and is an enlargement of one of the brake units already shown in Figure 1. The purpose of the picture is to show the position of the brake unit relative to the wheel (4).
Figure 3 shows the same brake unit in detail. The service brake cylinder is built-in and cannot be seen in the ﬁ clock.
The piston in this acts against the regulator which is hidden in the figure by a gurnmi bellows (10). The regulator acts against one of the brake arms (5). When the brake is applied, the brake lever (5) is pushed out at the regulator. This brake arm is then rotated around the joint (7), whereby the brake arm with its lining holder and lining (9) is pressed against the brake disc, which is not shown in this gear. The second brake arm (6) can rotate around the joint (8).
The two brake arms act as pliers that press the pads against the disc. Lateral adaptation to the brake disc is obtained by the ﬂ visible suspension of the brake unit (12) and (13) shown in figure 1.
The brake unit also has a parking brake cylinder (1 1). The mechanism for the parking brake is built-in and can not be seen in the figure, but the parking brake also acts against the regulator hidden by the rubber bellows (10) and the pads (9) and is applied in the same way as for the drive brake. There is a knob (14) for screwing in the regulator and opening the brake arms to enable pad replacement. There is an arm for manually applying the parking brake (15). The lu supply to the drive brake cylinder is obtained via a hose connected to the fitting (16) and to the parking brake cylinder via a hose connected to the fitting (17). The air is then led in a pipe (18) to the parking brake cylinder.
The design of brake units varies, of course, but the basic function is normally as described above.
Figure 4 shows an example of how the protection according to the invention encloses the brake unit. It encloses the entire brake unit except the brake arms against the wheel. The brake arms are thus led out through the protection in bushings (21), (22), (23) and (24). The cover is open downwards but sealed around the parking brake cylinder by tightening a strap (26) around the cover around this cylinder. This strip is shown in figure 5. In order to create a circular shape so that it becomes tight around the cylinder, foamed plastic (25) has been glued to the cylinder so that the pipe (18) is enclosed, however, a small opening has been left at the pipe which acts as a drainage path if water should penetrate the protection. The air hose to the drive brake (19) is led out through the protection in the bushing (27), the air hose to the parking brake cylinder (20) is led out through the bushing (28). The manual release sleeve (15) is led out through the cover in the bushing (29).
Figure 5 schematically shows the same example of protection according to the invention when it is closed. The principle of the closures is that the parts and flaps of the cover are mounted with a certain overlap and locked with Velcro or similar, which is exemplified by the fact that ﬂ ik 30 is overlaid ﬂ ik 33, ﬂ ik 31 is overlaid ﬂ ik 33. Tab 32 acts as a door over the knob for the regulator and also closes it with velcro or similar. This ﬁ gur also shows the mentioned clamping band (26).
The penetration of the hose to the parking brake cylinder (28) is done by making a hole in the fabric, then dividing the fabric downwards and by wrapping the ﬂ ikama and closing it with Velcro.
The bushing for the hose to the drive brake (27) is made in a similar way. Feed-through for the arm for manual release of the parking brake (29) is made by making an incision in the fabric and pulling the arm through.
Detailed description of the invention Overall The invention consists of a protection that is mounted over the brake unit to prevent ice formation on sensitive areas of the outside of the brake unit, i.e. which prevents the movements of the brake arms and regulator.
The protection is designed so that it encloses all sensitive parts of the brake unit but so that the brake arms closest to the brake disc pass through the protection so that these parts of the brake arms as well as the mounting brackets and pads are outside the protection. If the cover is made open in a direction where sensitive parts are not found, eg downwards, it is closed against the brake unit, eg with a lashing strap so that snow and slush can not enter the cover that way.
The protection is made as completely enclosing and tight as possible. An all-encompassing smooth protection is advantageous to minimize snow / ice build-up.
Design The protection according to the invention consists of one or two fabric parts that are applied over the brake unit.
The protection can of course also be designed in a slightly thicker material with double-curved surfaces that are adapted to the shape of the brake unit. The various parts and ﬂ ikama are laid and folded so that they overlap each other and are locked with Velcro or similar (eg 3M dual lock) so that the cover can easily be opened completely or even dismantled when required for sewing or maintenance. Any closures that do not need to be openable can also be glued or closed with double-sided adhesive tape.
The protection is further performed with ﬂ ikar that act as doors for sewing and adjusting the lining play in connection with the change of lining and a bushing for the release arm for manual release of the parking brake, alternatively with an ﬂ ik that acts as a door. The doors are closed with Velcro.
If required to obtain a satisfactory seal at the bushings for the brake arms, hoses and the device for the manual release or as in the example described above in color 4 above when sealing around the parking brake cylinder, soft seals are used. The seals can be loose parts or attached to the brake unit or to the protection.
Velcro straps are xered by gluing, sewing or welding.
The protection is carried out with at least one drainage path so that if water has penetrated, for example during de-icing, it does not collect in the protection but is drained out.
Mounting Part or ﬂ ik of the cover is inserted between the brake arms, ﬂ ik are pulled through the openings of the brake arms and under the brake arms and closed to the rest of the cover which is laid over the brake unit and folded down or around its sides. Any loose seals are fitted, any seals that are to be attached to the brake unit are fitted. The parts of the protection and the ﬂs, which of course lie with a certain overlap, are tightened around the bushings for the brake arms and the hose penetrations so that it becomes tight and is locked with the Velcro fasteners. When tensioning straps are used, these are mounted.
