Description

Technical Field

[0001] The utility model relates to the technical field of brake shoe supports, in particular to a brake shoe support with good heat dissipation effect. Background Art

[0002] Brake shoe supports are devices used to mount and secure brake shoes on locomotives and rolling stock. They are part of the braking unit. Their primary function is to convert the vehicle's kinetic energy into frictional heat between the brake shoe and the wheel, thereby achieving braking. Brake shoe supports work by converting air pressure into friction.

[0003] A large amount of heat energy is generated when the brake shoe rubs against the wheel. In order to ensure the normal operation of the brake shoe and achieve an effective cooling effect, the brake shoe support needs to have a good heat dissipation effect. The existing brake shoe support has a closed structure on both sides and a poor heat dissipation effect. Therefore, a good heat conduction and heat dissipation mechanism is needed to assist in the heat dissipation of the brake shoe. Utility Model Content

[0004] The utility model aims to solve the defects in the prior art and provides a brake shoe support with good heat dissipation effect.

[0005] The utility model is achieved through the following technical solutions:

[0006] A brake shoe support with good heat dissipation effect comprises a brake shoe support and a heat dissipation mechanism installed on both sides of the brake shoe support, the heat dissipation mechanism comprises a mounting plate, a clamping strip, an inserting plate, a contact plate, a connecting seat, a sleeve, a guide plate and a locking screw, the clamping strip is fixedly arranged on the inner side of the mounting plate, the inserting plate is clamped on the inner side of the clamping strip, the contact plate is fixedly arranged on the end of the inserting plate, the connecting seat is fixedly arranged on the outer side of the mounting plate, the sleeve is sleeved on the outside of the connecting seat, the guide plate is fixedly arranged on the outside of the sleeve, and the locking screw is connected to the end of the connecting seat.

[0007] In a preferred embodiment of the present invention, mounting holes for cooperating with the mounting plate are provided on both sides of the brake shoe support, the clamping strip is located on the inner side of the brake shoe support, and the connecting seat is located on the outer side of the brake shoe support;

[0008] The clip on the inside of the brake shoe holder is mainly used to install the contact plate. The contact plate contacts the surface of the brake shoe and dissipates the heat from the brake shoe surface through its good thermal conductivity. The external guide plate mainly guides more air into the brake shoe holder, thereby increasing the air flow and achieving a good heat dissipation effect.

[0009] In a preferred embodiment of the present invention, a guide groove is provided on the side where the clip strip is in contact with the mounting plate, and air flow holes are provided at the positions where the guide grooves on the mounting plate and clip strip surfaces match.

[0010] The guide groove on the inside of the card strip and the air flow holes on the outside of the mounting plate are mainly for facilitating air circulation.

[0011] In a preferred embodiment of the present invention, the deflector is arranged at an angle, the end of the sleeve is provided with a clamping hole that cooperates with the locking screw, and the end of the connecting seat is provided with a threaded hole that cooperates with the locking screw;

[0012] After loosening the locking screw, you can adjust the angle of the deflector. According to the installation angle of the brake shoe support, adjusting the angle of the deflector can better guide the air into the inside of the brake shoe support, thereby cooling the brake shoe. Tightening the locking screw can effectively fix the adjusted deflector.

[0013] In a preferred embodiment of the present invention, two contact plates are provided at one end of the inserting plate, the two contact plates are in a V-shaped structure, and the inserting plate and the contact plates are made of copper or aluminum alloy.

[0014] The beneficial effects of the utility model are:

[0015] The internal contact plate of the brake shoe holder with good heat dissipation effect effectively fits with the surface of the installed brake shoe, thereby transferring a large amount of heat generated by the friction of the brake shoe, and under the action of the external guide plate, the airflow is guided into the interior of the brake shoe holder. When the vehicle moves forward, the guided airflow acts on the surface of the plug plate and the contact plate, thereby quickly dissipating the heat and achieving a cooling effect.

[0021] The following detailed description of preferred embodiments of the present invention, combined with the accompanying drawings, will facilitate understanding of the advantages and features of the present invention by those skilled in the art, thereby more clearly defining the scope of protection of the present invention. Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0022] like Figure 1-4 The brake shoe support shown has good heat dissipation effect, including a brake shoe support 1 and a heat dissipation mechanism 2 installed on both sides of the brake shoe support 1, the heat dissipation mechanism 2 includes a mounting plate 21, a clamping strip 22, an inserting plate 23, a contact plate 24, a connecting seat 25, a sleeve 26, a guide plate 27 and a locking screw 28. The clamping strip 22 is fixedly arranged on the inner side of the mounting plate 21, the inserting plate 23 is clamped on the inner side of the clamping strip 22, the contact plate 24 is fixedly arranged on the end of the inserting plate 23, the connecting seat 25 is fixedly arranged on the outer side of the mounting plate 21, the sleeve 26 is sleeved on the outside of the connecting seat 25, the guide plate 27 is fixedly arranged on the outside of the sleeve 26, and the locking screw 28 is connected to the end of the connecting seat 25.

[0023] Specifically, mounting holes that cooperate with the mounting plate 21 are opened on both sides of the brake shoe holder 1, the clamping strip 22 is located on the inner side of the brake shoe holder 1, and the connecting seat 25 is located on the outside of the brake shoe holder 1. A guide groove is opened on the side where the clamping strip 22 is in contact with the mounting plate 21, and air flow holes are opened at the position where the guide grooves on the surface of the mounting plate 21 and the surface of the clamping strip 22 cooperate. The guide plate 27 is arranged at an angle, and a clamping hole that cooperates with the locking screw 28 is opened at the end of the sleeve 26, and a threaded hole that cooperates with the locking screw 28 is opened at the end of the connecting seat 25. Two contact plates 24 are provided at one end of the insert plate 23, and the two contact plates 24 are V-shaped. The insert plate 23 and the contact plate 24 are made of copper or aluminum alloy.

[0024] In this embodiment, after the heat dissipation mechanism 2 is clamped into the mounting hole on the surface of the brake shoe holder 1 and fixed with screws, the brake shoe is then installed inside the brake shoe holder 1. At this time, the outer side of the brake shoe will contact and squeeze the contact plate 24, and the contact plate 24 will fit tightly with the surface of the brake shoe. When the brake shoe generates a large amount of heat through friction, the contact plate 24 that fits with the surface of the brake shoe can effectively absorb and conduct the heat.

[0025] Furthermore, the guide plate 27 is installed, and the sleeve 26 with the guide plate 27 fixed thereon is sleeved on the surface of the connecting seat 25. The angle of the guide plate 27 is adjusted, and the locking screw 28 is tightened to lock and fix the sleeve 26 sleeved on the surface of the connecting seat 25, thereby fixing the rotation angle of the guide plate 27. During the driving of the vehicle, the airflow is guided by the guide plate 27 and enters the interior of the brake shoe support 1 through the airflow holes on the surface of the mounting plate 21, and circulates rapidly in the guide groove on the inner side of the clamping strip 22. The flowing air contacts the plug plate 23 on which the contact plate 24 is installed, and quickly takes away the heat. The plug plate 23 and the contact plate 24 made of aluminum alloy or copper effectively ensure the heat conduction effect, thereby ensuring the heat dissipation effect of the brake shoe. The improved heat dissipation effect further improves the braking effect of the brake shoe.
