In general, the importance of railway vehicles is increasing as their use increases gradually as a large-scale transportation means, and they are being constructed or operated to have a nationwide network. As a result of such quantitative expansion of railway, , Stability, comfort, and technological capability.

Such a railway is constructed such that a plurality of railroad ties are installed on the upper part of the base gravel and rails are installed on the upper part of the railroad tile, while a train which runs on the railway railway is used for decelerating the speed .

In particular, the railroad of Korea has a lot of routes passing through the mountain area, so that there are many uphill sections. Therefore, excessive heavy loads are applied to the engines of the trains during the operation of the trains. And the risk of derailment due to abrasion of train wheels.

In order to solve such a problem, a technique disclosed in Korean Registered Utility Model No. 20-0362089 as shown in FIGS. 1 and 2 has been proposed. In a railroad section of a steep slope region composed of a base gravel, a sleeper, and a rail, The sawtooth rail is fastened and fixed by a rail clip to be closely contacted with a toothed wheel installed at an end of a train fastener connected to the train so as to reduce the speed of the train, A plurality of anchor holes 41 are formed on both sides in the width direction and the sawtooth rail 40 has a plurality of rail clips 50 on the side surface thereof, The anchor holes 51 are formed in the lattice structure of the rail clip 50 and the fixed anchor nails 60 are fastened through the anchor holes 510The rake 40 is fixed to the sleeper 20 and the toothed wheel 90 is coupled to the connecting pin 73 of the fixed train fixture 70 by a connecting pin 93 to the toothed rail 40 A height adjustment jack 80 is installed on a jack connection port 75 protruding upward from the connection pin 73 of the railroad fastener 70 and the rail fastener 70 is mounted on a front side of the connection pin 73 And a gear wheel 90 is inserted into the groove 76 and is fastened by a connecting pin 93. [

However, the technology disclosed in Korean Registered Utility Model No. 20-0362089 uses the sawtooth rail 40 and the toothed wheel 90 to reduce the load that can be generated in the steep railway section, However, since the braking system is the same as that of a general railway vehicle, when the braking system is operated in the direction of descending the steep slope, the force between the rail and the wheel is not high. There is a problem that stable braking is difficult to be performed due to slipping, leading to a large accident.

The same reference numerals are used for the same constituent elements in the drawings and redundant explanations for the same constituent elements are omitted. It is to be understood that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

FIG. 3 is a conceptual diagram of an emergency braking device for a mountain railway vehicle according to the present invention, FIG. 4 is a braking state diagram of an emergency braking device for a mountain railway vehicle according to the present invention, FIG. 6 is a perspective view according to the embodiment of FIG. 5, and FIG. 7 is a braking state diagram according to the embodiment of FIG.

The present invention relates to an emergency braking device for a mountain railway vehicle in which a pinion gear (130) corresponding to a rack rail (120) installed on a mountain railway line is installed on a vehicle body (150) The hydraulic piston 160 is provided at a lower portion of the bogie 140 or the vehicle body 150 and a lower portion of the hydraulic piston 160 is brought into contact with the rack gear of the rack rail 120 to generate a braking force (200).

In this case, a control unit (not shown) for controlling the hydraulic piston 160 is provided in the mountain railway vehicle to operate the hydraulic piston in an emergency to perform emergency braking.

That is, in the case of performing normal running or normal braking without emergency braking, the braking unit 200 is kept apart from the rack rails 120 provided on the track by the control of the hydraulic piston 160 The braking unit 200 is moved downward under the control of the hydraulic piston 160 so as to be in contact with the rack gear of the rack rail 120 so that the frictional force between the braking unit 200 and the rack gear So that the mountain railway vehicle can be stopped more quickly.

The braking unit 200 includes a body 210 installed at a lower portion of the hydraulic piston 160 fixed to the lower portion of the vehicle 140 or the vehicle body 150, And an elastic member 212 provided between the braking member 214 and the body 210 to connect the braking member 214 and the body 210. [

4, the braking member 214 is brought into contact with the rack gear of the rack rail 120. When the braking member 214 is brought into contact with the rack gear of the rack rail 120, Since the member 212 elastically supports the braking member 214 downward, the braking force is increased by increasing the frictional force when the braking member 214 moves up and down along the gear ridge of the rack gear.

Here, the braking members 214 are provided in a plurality of rows, and the braking members 214 are sequentially inserted into the rack gears formed on the rack rails 120 in a row.

Accordingly, when the mountain railway vehicle is required to perform emergency braking at the time of traveling, each of the braking members 214 is inserted into the bones of the rack gears, thereby maximizing the frictional force and increasing the braking force, thereby enabling quick braking .

On the other hand, when the mountain railway vehicle performs the braking action, when the mountain railway vehicle is moved with each of the braking members 214 inserted into the bones of the rack gear, The braking force is increased in the process of moving to the upper part.

Here, since the speed of the mountain railway vehicle starts at the time of starting the emergency braking, it is difficult to move the braking members 214 to the upper part when the braking members 214 are inserted into the ridges of the rack gears. The members 214 are easily broken. In the present invention, each of the braking members 214 is made of rubber or synthetic rubber having good elasticity so that the braking member 214 is bent without bending when the running speed of the mountain railway vehicle is fast Thereby preventing the braking member 214 from being damaged while increasing the braking force, thereby enabling stable braking.

5 and 6, a hydraulic piston 160 may be provided at a lower portion of a bogie 140 or a vehicle body 150 forming a mountain railway vehicle. In the hydraulic piston 160, The bending unit 200 is provided with a body 220 formed in a cylindrical shape and a cutout 222 formed in the front and rear of the body 220. The bending unit 200 ' And an elastic member 224 connecting the auxiliary braking member 226 and the body 220. [

7, when the braking portion 200 'is moved downward by the hydraulic piston 160 during the emergency braking operation, the cutout portion 222 is formed to be equal to or larger than the width of the rack rail 120, The cutouts 222 are inserted into the cutouts 222 so that the cutouts 222 are brought into contact with the sides of the rack rails 120 to generate a frictional force to increase the braking force.

The auxiliary braking member 226 is provided with a plurality of auxiliary braking members 226, which are inserted into the bones of the rack gear as in the above-described embodiment, thereby increasing the braking force.

In addition, each of the auxiliary braking members 226 is made of rubber or synthetic rubber, thereby preventing the auxiliary braking member 226 from being broken even if the speed of the mountain railway vehicle is fast, thereby enhancing durability.

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the scope of the present invention is not limited to the disclosed embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.

The present invention relates to an emergency braking device for a mountain railway vehicle, and more particularly, to an emergency braking device for a mountain railway vehicle capable of safely braking a mountain railway vehicle by generating a stable braking force even when an emergency braking is required, To a braking device.
