Description

Technical Field

[0001] The invention relates to the technical field of monorail vehicle bogies, and mainly relates to a temperature control device for a braking system of a monorail vehicle bogie. Background Art

[0002] A monorail vehicle is a type of train that is characterized by using only one track instead of the two balanced tracks of traditional trains. Monorail vehicles are usually wider than tracks and are mainly used in densely populated urban areas to carry passengers. Monorail vehicles are generally divided into two categories, one is a suspended monorail and the other is a straddled monorail. The straddled monorail is a type of rail transit system that is supported, stabilized and guided by a single track, with the car body riding on the track beam with rubber tires. The bogie is installed at the bottom of the train, straddling the track beam, and the running wheels on the bogie allow the train to move along the track.

[0003] In order to enable the monorail vehicle to adjust the speed or stop, a braking system is usually installed on the bogie of the monorail vehicle. By installing a brake disc and clamping the brake disc with a brake brake or a brake clamp, the monorail vehicle can be decelerated until it stops, so as to control the vehicle's travel speed. However, during the braking process, the brake disc and the brake clamp will generate a lot of heat due to long-term contact and friction, causing the temperature of both to rise sharply, which will not only affect the braking effect, but also shorten the service life of the brake disc to a certain extent. Its overall use is inconvenient and there are certain safety risks. Therefore, it is necessary to propose an improvement measure to solve the above technical problems. Summary of the invention

[0004] The present invention provides a temperature control device for a monorail vehicle bogie braking system, which is used to solve the technical problems raised in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a temperature control device for a monorail vehicle bogie braking system, comprising a frame, on which a running wheel, a transmission shaft, a fixing seat, a power assembly, a brake disc and a brake clamp are correspondingly installed; an annular cooling liquid cavity is correspondingly arranged around the brake disc, and both sides of the cooling liquid cavity on the brake disc are correspondingly provided with an annular and inwardly concave arc-shaped groove, and the groove bottom of the arc-shaped groove is correspondingly provided with a plurality of through holes; a liquid storage cavity is correspondingly arranged in the fixing seat on one side of the brake disc, and the liquid storage cavity is correspondingly connected with the cooling liquid cavity; when the temperature on the brake disc exceeds a specific value, the cooling liquid in the liquid storage cavity will be driven to be input into the cooling liquid cavity of the brake disc to cool the brake disc; when the temperature on the brake disc is lower than a specific value, the cooling liquid in the cooling liquid cavity on the brake disc will be driven back to the liquid storage cavity of the fixing seat on one side of the brake disc for cooling and storage.

[0006] Preferably, fixed seats are installed on both sides of the transmission shaft, and the transmission shaft is rotatably connected to the fixed seats; a connecting column is provided at the center hole in the middle of the brake disc, the connecting column is installed on the transmission shaft, and the running wheel is installed on the connecting column; a column ring is provided on the inner side of the fixed seat with a liquid storage cavity opened inside, a small water pump is installed on the top of the fixed seat, and one end of the connecting column is rotatably installed in the column ring; a conveying channel is provided inside the connecting column, one side of the conveying channel is connected to the cooling liquid cavity, and the other side of the conveying channel is connected to one end of the small water pump, and the other end of the small water pump is connected to the liquid storage cavity in the fixed seat.

[0007] Preferably, an annular groove is correspondingly provided on the inner side of the column ring, and an annular clamping ring is provided at a corresponding position on one side of the connecting column tube, and the annular clamping ring is rotatably installed in the annular groove on the inner side of the column ring; a connecting cavity is correspondingly provided at the bottom of the annular groove on the inner side of the column ring, and a first flow channel is correspondingly provided around the annular clamping ring on the connecting column tube, the first flow channel is correspondingly connected to the connecting cavity, and one end of the small water pump is correspondingly connected to the connecting cavity; an annular inner cavity is correspondingly provided in the connecting column tube between the brake disc and the column ring, one side of the annular inner cavity is correspondingly connected to the first flow channel, and the other side of the annular inner cavity is correspondingly connected to the cooling liquid cavity through the second flow channel.

[0008] Preferably, a temperature sensor can be installed in the arc-shaped groove on one side of the brake disc, and semiconductor cooling plates can be installed on both sides of the lower part of the fixed seat with a liquid storage cavity inside. The temperature sensor, semiconductor cooling plate and small water pump are all connected to the external control system accordingly.

[0009] Preferably, the arc-shaped grooves on the two side surfaces of the brake disc are recessed from the center to the edge, and the multiple through holes at the bottom of the arc-shaped grooves are evenly spaced and distributed in the circumferential direction.

[0010] Preferably, two positioning clamps are provided on the connecting cylinders on both sides of the brake disc, and the running wheels include two, which are respectively installed between the two positioning clamps on the connecting cylinders on both sides of the brake disc; the transmission shaft is connected to the output end of the powertrain for transmission, and the brake clamp pre-clamps the brake disc; and stabilizing wheels and guide wheels are also installed on both sides of the lower part of the frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention optimizes the design of the brake disc, fixing seat and other component structures on the bogie. By correspondingly arranging annular and inwardly recessed arc-shaped grooves and a plurality of through holes on both sides of the brake disc, when the brake disc rotates, air will be blown into the groove along the arc-shaped grooves on both sides and blown out from the through holes, so as to perform air cooling and dissipate heat on the brake disc, so as to reduce the temperature of the brake disc. The arc-shaped groove design can also effectively increase the contact area between the brake disc and the air without affecting the clamping brake of the brake clamp, thereby improving the heat dissipation effect of the brake disc.

[0012] In addition, the present invention is also equipped with a small water pump, a temperature sensor, a semiconductor cooling plate and other components. When the brake clamp clamps the brake disc for braking, if the temperature sensor detects that the temperature on the brake disc exceeds a specific value, the small water pump will send the coolant in the liquid storage cavity on the fixed seat into the coolant cavity of the brake disc to cool the brake disc by water; when the temperature sensor detects that the temperature on the brake disc is lower than the specific value, the small water pump will return the coolant in the coolant cavity on the brake disc to the liquid storage cavity of the fixed seat for natural cooling and storage. At this time, the semiconductor cooling plate can also be controlled to work, so that the coolant heated in the liquid storage cavity cools down faster, so as to quickly adapt to the next braking work. The brake disc is correspondingly installed between the two running wheels, and the liquid storage cavity is correspondingly arranged in the fixed seat. There is no need to set an additional liquid storage tank on the frame, which is more convenient to install and use. At the same time, it also effectively ensures that the space size of the overall structure of the bogie will not increase. The overall structural design is ingenious, the overall cooling effect of the brake disc is good, and the braking effect and service life of the brake disc are well guaranteed, and the practicality is strong.
