It is shown that the first and second zero-order braking means 30 is composed of a pair of disk pad housing 40 coupled to the other and the disk pad 38 is coupled to the other inner surface.

In addition, a disk plate 44 having a disc shape having a predetermined radius of curvature provided in the center of the axle 42 is provided between the disk pad 38 and the disk pad 38 so as to maintain a constant gap.

In the figure, reference numeral A denotes a first relay edge, and B denotes a second relay edge.

Referring to the use state of the present invention as follows.

1 to 3, the first relay communicates with the inlet pipe 12 in a wagon in which a plurality of wheels 18 are coupled to each other by the axle and the axle roller housing 50 on the side frame 48. In the initial state where the side (A) is installed and each wheel 18 is provided with a tolerance braking means 10 and the axle 42 is provided with a first and second order vehicle braking means 30 and a disk plate 44, When the vehicle is to be braked while operating in a tolerated state, a separate automatic lever (not shown in the drawing) is driven to supply air having a constant pressure through the inlet pipe 12 to the first braking tube 14 and the second. When supplied to the braking cylinder 16, the air supplied to the first and second braking cylinders 14 and 16 pushes the piston rods 14a and 16b forward by a predetermined distance.

In this state, the piston rods 14a and 16a are rotatably coupled to the side frame 48 and the other end of the wheelset housing 24 and the hinge 22 to which the wheelset 20 and the lever 22 are coupled. Since the link 28 coupled to 26 is coupled, the wheelset housing 24 is pushed backward in proportion to the forward travel distances of the piston rods 14a and 16a, thereby driving the wheelset 20 to the wheel ( 18) to generate braking force.

At this time, since the connecting rod 46 is coupled to the lever 22 coupled to the wheelset housing 24 so that each wheelset housing 24 can be interlocked, the wheelset 20 is simultaneously driven to drive each wheel ( Braking is achieved in contact with 18).

On the other hand, when a certain amount of cargo is loaded into the wagon while braking while driving, the air supplied through the inlet pipe 12 passes through the first relay valve A through the cock 32 and the first disk brake barrel 34. It is supplied to drive the piston rod (34a) to advance by a certain distance.

At this time, the piston rod 34a is connected to the disc housing 40 to which the disc pad 38 is coupled and rotated by a predetermined angle from the hinge point, and each disc housing 40 is connected by the link 28 '. While interlocking, the disk pad 38 comes into contact with the disk plate 44 coupled to the axle 42 to obtain a braking force during the first zero car.

In addition, when the truck is loaded with a greater amount of cargo than in the case of the first zero car as described above, the vehicle is braked while driving, and the air supplied to the first relay side A through the inlet pipe 12 receives the second relay side ( It is supplied to the second disk braking tube 40 'via B) to perform the same operation as in the first zero car braking to obtain a braking force in the second zero car.

For example, the pressure P and the braking distance S generated during the tolerance braking and the first and second zero-braking braking will be described below.

That is, pressure P = 14307 kg,

That is, the braking distance S is 631m, and (b) the first zero car
