Embodiment 1

[0043] like figure 1 As shown, the drawbar trailer braking system includes an air storage container 24, a release valve 29 and an emergency relay valve 28. The air storage container 24 has a container air inlet 23 and a container air outlet 22, and the container air outlet 22 is arranged on the air storage container. One end of 24, container air inlet 23 is arranged on the middle part of gas storage container 24.

[0044] In this embodiment, the release valve 29 has a release valve inlet 15, a release valve outlet 17, a release valve interface 18, and a parking interface 19; the emergency relay valve 28 has a relay valve outlet 14, a first relay valve The air inlet 25 , the relay valve interface 26 and the second relay valve air inlet 27 . Wherein, the air storage container 24 is an air storage cylinder. In other embodiments, the gas storage container may be a gas cylinder.

[0045]In this embodiment, the air inlet 15 of the release valve is in communication with the air su...

Embodiment 2

[0054] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the release valve 29 is provided with a moving button 16, and the connection between the release valve outlet 17 and the release valve interface 18 is realized through the moving button 16, so that the gas storage container The air pressure in 24 flows into the second relay valve air inlet 27 through release valve 29, to release the brake to drawbar trailer. In this embodiment, there is no moving button on the release valve. When the vehicle needs to be moved, re-connect the control pipeline of the tractor to the emergency relay valve, and connect the air supply pipeline of the tractor to the release valve. The air supply pipeline supplies air again to the air inlet 27 of the second relay valve through the release valve, so as to release the brake of the drawbar trailer.

Embodiment 3

[0056] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, a parking button 20 is provided on the release valve 29, and when the parking button 20 cuts off the release valve interface 18 and the parking interface 19, the parking of the drawbar trailer is realized. Car; when the parking button 20 communicates the release valve interface 18 with the parking interface 19, the parking of the towbar trailer is released. In this embodiment, no parking button is provided on the release valve, the gas storage container is directly connected to the trailer parking pipeline, and a parking control valve is set on the trailer parking pipeline, and the parking control valve controls the disconnection of the trailer parking pipeline. When the parking control valve controls the connection of the trailer parking pipeline, the parking of the drawbar trailer is realized, and the parking of the drawbar trailer is released.

Abstract

The invention relates to a braking system of a drawbar trailer and a drawbar trailer. The brake system of the tow bar trailer includes: an air storage container with an air inlet of the container and an air outlet of the container; a release valve with an air inlet of the release valve, an air outlet of the release valve and an interface of the release valve. The air supply pipeline of the tractor is connected, and the release valve interface is connected with the air outlet of the container; the emergency relay valve has the air outlet of the relay valve, the air inlet of the first relay valve, the air inlet of the second relay valve and the interface of the relay valve , the outlet of the relay valve is used to connect with the brake control valve of each axle, the inlet of the first relay valve is used to connect with the control pipeline of the tractor, the interface of the relay valve is connected with the inlet of the container, the second relay valve The air inlet communicates with the air outlet of the release valve. After the air supply pipeline of the tractor and the control pipeline of the tractor are disconnected or broken, the drawbar trailer can automatically generate emergency braking to avoid safety accidents caused by loss of braking ability.

Description

technical field [0001] The invention relates to a braking system of a drawbar trailer and a drawbar trailer. Background technique [0002] Trailers are generally divided into two types, one is a semi-trailer, the semi-trailer and the tractor are connected through a saddle, and the connection is relatively stable; the other is a drawbar trailer, and the drawbar trailer and the tractor are connected through a tow hook. It is a single-point connection with poor stability, and the connection position is easily damaged during driving. [0003] In the prior art, the braking of the drawbar trailer is realized through the air circuit between the drawbar trailer and the tractor. After the above-mentioned connection position between the drawbar trailer and the tractor is damaged, it is easy to cause the drawbar trailer to be thrown out, thus causing the air path between the drawbar trailer and the tractor to be disengaged or broken, and the drawbar trailer cannot be braked, resulting...
