Problems solved by technology

However, since the common ABS system needs to install an emergency relay valve in front of the control port, this will cause disadvantages such as mismatching between the valves and increasing pipeline joints.
Although CN1919668A discloses an ABS emergency relay valve, the structure of the valve body is too complicated, the processing cost is also high, and once a certain part of the valve fails, the whole valve needs to be replaced

Embodiment Construction

[0016] Figure 1 is an integrated view of a preferred embodiment of the present invention. In this embodiment, the emergency relay and ABS dual-cavity relay integrated valve of the present invention are integrated by a miniature emergency relay valve, an ABS solenoid valve, and a dual-chamber relay valve, and two sets of ABS solenoid valves each contain two solenoid valves. The valve is installed on the double-chamber relay valve, and the solenoid valve controls the output pressure of the double-chamber relay valve to increase, maintain and decrease. The air inlet (1-2) of the miniature emergency relay valve is connected and fixed with one of the air inlets (1-3) of the double-cavity relay valve, and the output port (2) of the miniature emergency relay valve is connected with the double-cavity relay valve. The control port (5) of the cavity relay valve is connected as a whole.

[0017] In this embodiment, the miniature emergency relay valve includes a control relay piston (a),...

Abstract

The invention provides an emergency air brake relay valve integrated with an ABS dual-chamber relay valve, which can be used in an air braking system of a trailer or a semi-trailer. The emergency relay valve integrated with the ABS dual-chamber relay valve comprises a mini-emergency relay valve, two sets of ABS electromagnetic valves each of which is provided with two electromagnetic valves and a dual-chamber relay valve which can control the increase, maintenance and decrease of the output pressure by virtue of the electromagnetic valves, wherein, air inlets (1-2) of the mini-emergency relay valve are connected and fixed with one of air inlets (1-3) of the dual-chamber relay valve; an output port (2) of the mini-emergency relay valve is connected with a control port (5) of the dual-chamber relay valve as a whole. The emergency air brake relay valve integrated with the ABS dual-chamber relay valve has the functions of safe braking, service braking, ABS braking and emergency braking, thus improving the safety performance in vehicle driving.

Description

technical field [0001] The invention relates to an emergency relay and ABS dual-cavity relay integrated valve, which belongs to the technical field of automobile air brake components. technical background [0002] With the enforcement of my country's national standard GB7258-2004 "Technical Conditions for Motor Vehicle Operation Safety" and GB / T13594-2003 "Performance Requirements and Test Methods for Automobile Anti-lock Braking Devices", semi-trailers, the main types of road transportation in my country, must be installed ABS system. This is an effective measure to improve the safety performance of the vehicle. However, since the common ABS system needs to install an emergency relay valve in front of the control port, this will cause disadvantages such as mutual mismatch between the valves and additional pipeline joints. Although CN1919668A discloses an ABS emergency relay valve, the structure of the valve body is too complicated, the processing cost is also high, and onc...
