Description

[0001] DIRECT-APPLIED TYPE ELECTROMAGNETIC BRAKING SYSTEM [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic braking system, and more particularly, to a direct acting electromagnetic braking system in which an electromagnetic force acts directly on a brake disk.

In a conventional braking system applied to braking on railroad cars or large vehicles, a system using pneumatic or hydraulic pressure is applied to apply a frictional force, and a pneumatic or hydraulic pressure is applied to a pressure surface requiring braking, As shown in FIG.

However, in the case of the braking system using the pneumatic or hydraulic pressure, separate devices for generating pneumatic and hydraulic pressures are required. In particular, piping and connection lines for circulating pneumatic or hydraulic pressure to the braking section are essential. Accordingly, efforts must be made to optimize the design of the pneumatic or hydraulic connection piping in the braking system, and the space occupied by the braking system and related devices increases, thereby increasing the volume of the overall braking portion.

For example, Korean Patent Application No. 10-1998-0062256 or No. 10-2001-0030858 discloses a structure of a hydraulic braking system, but it is not easy to design due to its complicated structure, There is a problem in that it is incompatible with the tendency of weight reduction and simplification of vehicles in recent years.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide an electromagnetic braking system in which weight and simplification of a vehicle and ease of design are improved.

An electromagnetic braking system according to one embodiment for realizing the object of the present invention includes a braking disk and a braking unit. The brake disk is fixed to the axle and rotates. Wherein the braking portion includes an electromagnetic force portion generating an electromagnetic force with the brake disk, a frame portion moving in the direction of the brake disk according to the generation of the electromagnetic force, and a braking portion fixed on the frame portion, And a friction member for applying a frictional force to the disk.

In one embodiment, the electromagnetic force portion can generate attraction force with the brake disk in accordance with application of a current or a voltage, thereby moving the brake portion in the direction of the brake disk.

In one embodiment, the brake disk may have a circular disk shape comprising first and second surfaces facing each other and a circumferential surface connecting between the first and second surfaces.

In one embodiment, the braking portion includes a first braking portion contacting the first surface of the braking disk to brak the braking disk, and a second braking portion contacting the second surface of the braking disk to braking the braking disk, And a braking unit.

In one embodiment, the braking portion may contact the circumferential surface of the brake disk to brak the brake disk.

In one embodiment, the electromagnetic force portion is disposed at both ends of the frame portion in a pair, and may be any one of a general electromagnet, a hybrid electromagnet, or a permanent magnet.

In one embodiment, the frame portion may be flat. The electromagnetic force unit may include an electromagnetic portion that is fixed in contact with the frame portion, and a coil portion that is wound at a center of the electromagnetic portion to be spaced apart from the frame portion.

In one embodiment, the frame portion may have a stepped portion formed at a center away from the brake disk, and a stepped portion on which the friction member is mounted. The electromagnetic force part may include an electromagnetic part fixed to both ends of the frame part, and a coil part wound at the center of the electromagnetic part so as to be spaced apart from the step part.

In one embodiment, the braking unit may further include a heat dissipating unit fixed to an outer surface of the electromagnetic force unit and radiating heat generated from the electromagnetic force unit.

According to the embodiments of the present invention, since the braking unit moves in the direction of the braking disc by the electromagnetic force generated between the electromagnetic force unit and the braking disc, the braking disc is braked. Therefore, compared with the conventional braking system using pneumatic or hydraulic pressure It is possible to design a braking system relatively simple, and it is possible to realize a lightweight and compact design.

Particularly, it is possible to control the magnitude and time of contact of the braking unit with the brake disk by variably controlling the current and the voltage applied to the electromagnetic force, thereby facilitating the braking control.

Further, the shape and arrangement of the electromagnetic force portion and the friction material can be variously changed, and various designs can be made according to the shape of the brake disk, the braking condition, and the like.

In particular, the design of the electromagnetic force portion, the frame portion, and the friction member can be variously changed so that the braking portion can brakes not only on both sides of the brake disk but also on the circumferential surface of the brake disk.

In addition, the electromagnetic force section can be constituted by a hybrid electromagnet, a permanent magnet, or the like in addition to the general electromagnet, so that diversity according to the design need can be improved.

Furthermore, heat generated by application of a current or a voltage through the heat dissipation unit connected to the electromagnetic force can be effectively dissipated, and durability and operational reliability can be improved.

1 is a cross-sectional view of an electromagnetic braking system according to an embodiment of the present invention.

Referring to FIG. 1, the electromagnetic braking system 10 according to the present embodiment includes a brake disk 100 and a braking unit 200.

The brake disk 100 is fixed to the axle 1 and rotates about the axle 1 integrally with the rotation of the axle 1. The braking disc 100 includes a pair of facing first and second side surfaces 101 and 102 and a circumferential surface 103 connecting the circumferences of the first and second side surfaces 101 and 102 do.

That is, the braking disc 100 has a circular plate or cylinder shape having a thickness equal to the width of the circumferential surface 103, and is fixed to the axle 1 and rotates.

However, since the second braking unit 220 has the same structure and shape except that the second braking unit 220 is disposed symmetrically with respect to the first braking unit 210, the second electromagnetic force unit 221, A detailed description of the second frame portion 223 and the second friction member 224 will be omitted for the description of the first braking portion 210, and redundant description will be omitted.

The first electromagnetic force part 211 is fixed to both ends of the first frame part 213 and generates an electromagnetic force with the brake disk 100 according to a current or voltage applied from the outside. In this case, when a force is generated between the first electromagnetic force part 211 and the braking disc 100, the first braking part 210 moves in the direction of the braking disc 100.

Thereafter, when a current or voltage in a direction opposite to the direction first applied to the first electromagnetic force section 211 and the second electromagnetic force section 221 is applied, the first shunt section 210 and the second shunt section 221 220 return to the initial position of FIG. 1, and the brake disk 100 is rotated in accordance with the rotation of the axle 1.

Alternatively, the application of the current or voltage to the first electromagnetic force section 211 and the second electromagnetic force section 221 is stopped, and the first shunt section 210 and the second shunt section 220 move The first and second shaking portions 210 and 220 return to the initial positions in FIG. 1 as well.
