1015202530mechanical means, and if no actuator spring 22 is present, it decreases againstthe brake pads employ the braking force, since the longitudinal displacement of the brake transmitter hasa fixed value. However, by using an actuator spring 22, it is compensatedrequired extra longitudinal displacement by the extension of the actuator 22, sothat braking force is generated by extending the actuator spring 22 as the brake blocks movealong the rail vehicle wheel. The actuator spring 22 is thus used to engage onebraking force on the brake pads, even then no further longitudinal displacement ofthe bridge transmitter 11 is available. The brake transmitter is attached to a rigid indicator barThe brake indicator further comprises a brake indicator arrangement 24, which isfixedly mounted to the vehicle structure and has an indicator 241, which is slidablemounted in a recess 242 in the bridge indicator arrangement 24. The indicator 241 is fixedat the other end of the indicator rod 23. Then the parking brake transmitter 1 1 thusmoved longitudinally, eg by means of the mechanical member, the indicator 241 movessimultaneously in the recess 242 in the bronze indicator arrangement 24. An ON and OF F signis arranged on the bronze indicator arrangement 24 to visualize the brakedrespectively unbraked position. Fig. 2b illustrates the brake indicator in a braked position, inwhich the parking brake transmitter has been moved longitudinally to the left and broughtindicator 242 to the ON position.
In the solution according to Fig. 2a and Fig. 2b, however, there is a risk thatthe parking braking force is too high or too low, as it is only the longitudinal displacementwhich is measured. No real measurement of braking force is achieved. About the braking forceshould be too high, there is thus a risk of damage to the braking equipment. On the otheron the other hand, there is also a risk that a too low braking force is applied, since no braking forcemeasured.
It would thus be advantageous to provide a new oneparking brake indicator system and a new parking brake indicator device forachieving increased reliability and security.

However, the invention can be practiced on many othersmethod and shall not be construed as limited to the embodiments set forth below. Theseembodiments are rather provided, so that this description should be detailed andcomplete and sets out the framework of the invention for those skilled in the art. The embodimentsdoes not limit the invention, but the invention is limited only by the appendedpatent claims. The terminology used in the detailed description of theFurthermore, the forms of lithography illustrated in the accompanying drawings are not intended tolimit the invention.
The following description focuses on embodiments that can be utilized ina parking brake indicator system.
An underlying idea of the present invention is to provide oneparking brake indicator system and a parking brake indicator device as merelytakes into account the actual braking force applied to rail wheels or discs.
In a first embodiment, according to Figs. 3a-3d, there is oneparking brake indicator system 30. Figs. 3a and 3b illustratethe parking brake indicator system, when no braking force is applied. Figs. 3c and 3dillustrates the parking brake indicator system at different applied braking forces, and in fig 3dan appropriate maximum braking force is indicated by a brake indicator 35.
The parking brake indicator system 30 includes a parking brake transmitter31, which transmits power from, for example, an air cylinder or by means of mechanical means (notshown) against the brake system connected to the rail wheel or disc (not shown).
The parking brake transmitter 31 includes a resilient member 32, such as a spring, attached to itone end at the housing of the parking brake transmitter 31 and at the other endat the end of a rigid indicator tube 33. The other end of the indicator tube 33 is attached to aindicator panel 35, which is visually accessible from the outside of the rail vehicle.The indicator panel is slidably mounted in a recess 341 of abrake indicator arrangement 34, which is fixedly mounted in the rail vehicle structure.
The brake indicator panel 35 thus follows the movement of the parking brake transmitter 31as well as the compression and elongation of the resilient member 32. It is of largeweight that the indicator tube is directly connected to the end of the resilient part 32,since this allows the indicator panel 35 to move relative tothe brake indicator arrangement 34, and the movement of the indicator panel 35 relative to1015202530the brake indicator arrangement 34 thus depends both on the level of compression of itresilient part 32 and the longitudinal displacement of the brake transmitter 31. Since the wire36 is attached to the brake transmitter 31, the indicator panel 35 also moves with atthe longitudinal displacement of the brake transmitter 31. When the braking force is greater than the spring forceof the resilient member 32, the brake indicator 351 begins to rotate to therebyindicate compression of the resilient member 32, which in turn indicates itemployed braking force. Thus, the brake indicator 351 merely indicates it onthe braking system of the rail vehicle employed braking force.
The resilient part 32 can thus be selected in such a way that its spring force is inthe same order of magnitude as the desired braking force to be applied to the rail vehiclebraking system. The spring force of the resilient part 32 can thus be selected in such a way that itthey fi nier the initial braking force level at which the brake pads start to brakethe rail vehicle. When the braking force exceeds this initial braking force level, it is compressedthe resilient member 32, whereby the brake indicator 351 rotates further.
The indicator panel 35 includes a brake indicator 351, which may be an arrow withthe base end 359 rotatably mounted on the indicator panel 35, whereby the arrow can rotatearound its base end 359. However, any suitable brake indicator can be used.
The parking brake indicator system 30 further includes a wire 36, which ismounted at one end by the parking brake transmitter 31, as illustrated in fi g3a-3b. The wire 36 is preferably made of a sufficiently inexplicably robust material,such as steel. However, any suitable wire can be used. The wire 36 canextend through a channel 357 in the rigid indicator tube 33 and is at its other endmounted to the brake indicator 351, by means of a mounting knob 3512, at a position abovethe base end of the brake indicator 351.
The wire can alternatively extend through a part 358, which projects fromthe indicator panel 35, via a hole 358, as indicated in Fig. 4, which illustratesthe brake indicator arrangement in more detail. The part 358 works to stabilize andalign the wires 36 along the indicator panel 35.
When the braking force exceeds the spring force of the resilient part 32, it beginsthe resilient member 32 to be compressed. Under compression of the resilient member 32,i.e. when the brake transmitter is pushed longitudinally (to the left in Figs. 3a-3 d), pullthe brake transmitter enters the wire and thereby rotates the brake indicator 351 around itbase end 359, as illustrated in Figs. 3G and 3d. The direction of rotation of the brake indicator35 then visually indicates the actual braking force applied by the brake transmitter 31.101520253035The indicator panel 35 may be provided with an "ON" mark or tag,as illustrated in 3 g 3a-3d. The "ON" tag indicates together with the direction ofthe brake indicator that a suitable braking force has been applied. At a certain braking force level, thenthe brake indicator 351 points to the "ON" tag, thus indicating that a suitablebraking force is applied to the brakes. Exceeding this braking force can have negativeseffects on the brake. However, a lower braking force can have the effect that the train startsroll in an undesirable manner. The brake indicator arrangement 34 may be provided with a"OFF" tag or marking to indicate when no braking force is applied. When no onebrake force is applied, the brake indicator 351 points to the "OF F" tag onthe brake indicator arrangement, as illustrated in Fig. 3a.
Figures 5a-5d illustrate the parking brake indicator system according to the secondthe embodiment in a more practical design.In Figs. 5a-5d, it can be observed that the brake indicator 351 is provided with a slot351 l, in which a fastening knob 3512 is slidably mounted. The mounting knob 3512 is attached towire 36 and can also slide along a recess 353 in the indicator panel 35. The functionof the fixed knob 3512 is to stabilize the brake indicator 351 at the indicator panel 35,while a constant perpendicular distance between the mounting position forthe base end of the brake indicator 351 and the extension of the indicator tube 33 are made possible toavoid unnecessary bending or abrasion of the brake indicator 351 in use.Figs. 3a-3d and Figs. 5a-5d are the indicator tube 33 through which the wire 36 extends.mounted in a holder 311, which is attached to one end of the resilient member32. However, the indicator tube 33 may also be directly attached to the resilient member 32.
Fig. 6 illustrates the parking brake indicator system mounted on an existing onewheel construction. The left side of the brake transmitter 31 is connected tothe brake system (not shown) of the rail vehicle, while the right side of the brake transmitteris connected to the air cylinder (not shown) or the mechanical means (not shown).
Figures 7a-7c illustrate a third embodiment ofthe parking brake indicator system. Fig. 7a illustrates the parking brake indicator system,when no braking force is applied. Fig. 7b illustrates the parking brake indicator systemunder construction of braking force. Fig. 7c illustrates the parking brake indicator system,when a suitable maximum braking force is indicated by the brake indicator 3512. I fi g 7a-7cthe brake indicator arrangement comprises an indicator panel 35 with a recess 353,which is parallel to the extent of the indicator tube 33, in which recess 353the mounting knob 3512 is slidably mounted. The mounting knob 3512 is attached to the end of the wire 36.
The indicator panel is provided with an "ON" tag and an "OFF" tag, and the position of101520253035the fixed knob 3512 in relation to the "ON" and "OFF" tags indicates the level of itemployed braking force. The mounting knob 3512 thus acts as a brake indicator 351 inin accordance with the foregoing, except that the mounting knob 3512 does not rotatewhen the braking force exceeds the spring force of the resilient part. The functionality ishowever, the same, since the fixed knob 3512 is connected to the resilient part32, whereby the fixed knob will move towards the "ON" tag belowthe compression of the resilient member 32.
In the above embodiments, the wire is arranged in a channel of the indicator tube 33,but it is equally possible to arrange the wire separately from the parking brake transmitter 31to the brake indicator 35, when no channel is provided in the rigid indicator tube 33.
Figures 8a-8c illustrate a spring design of a parking brake transmitter81, which is arranged to be visually accessible from the outside of the rail vehicle. On the sameIn the same way as the previous embodiments, the parking brake transmitter 81 comprises aresilient member 82, such as a spring. The parking brake transmitter 81 further comprisesan indicator wheel 83 having a threaded hole therethrough, in which threaded hole onebrake shaft (right side of the brake transmitter) of the parking brake transmitter 81 witha corresponding threaded portion is provided. Attached to the indicator wheel 83 can aindicator lever 84 be attached. In Figures 8a-8c, the left side of the brake transmitter 81be connected to the braking system (not shown) of the rail vehicle, while the right side ofthe brake transmitter may be connected to an air cylinder or a mechanical means (notshown). Then a braking force is built up with the help of the air cylinder or the mechanicalthe member begins to compress the resilient member 82. The resilient part is at aside fixed to the brake shaft 85, as shown in Figs. 8b and 8c, which makes it possible forthe resilient part to be compressed by means of the air cylinder or the mechanicalthe body. When the resilient member 82 is compressed, the brake shaft 85 is moved with itthreaded the portion to the right in fi g 8a-8d, whereby the indicator lever 84 rotates andindicates the applied braking force.
