Problems solved by technology

The pneumatic braking system is the most commonly used braking system for heavy-duty fuel vehicles. As the requirements for braking performance increase, the braking system should also reduce the driver's work intensity as much as possible. At present, most of the control devices for pneumatic braking It is composed of air pressure control components such as brake pedal mechanism and brake valve. Heavy-duty vehicles or vehicles that often drive in mountainous areas need to brake in time due to unknown dangers, so an efficient emergency braking system is needed. Most of the research on this aspect uses ordinary manual parking brakes, which react slowly to emergencies and cause frequent accidents.

Embodiment 1

[0034] Embodiment one: if Figure 1-11As shown, the present invention is based on a high-efficiency braking system for heavy-duty trucks, including a housing 1, a working diaphragm 2 located inside the housing 1, a pusher driven by the working diaphragm 2 and protruding from the opening of the housing 1. Rod 3, the inside of the housing 1 is provided with a spring 4 sleeved on the outside of the push rod 3, and the housing, working diaphragm, push rod and spring constitute a diaphragm brake chamber 5; the working diaphragm 2 is far away from the push rod. One side of the rod 3 is provided with an emergency brake diaphragm 6 for driving the push rod 3 to protrude from the opening of the housing 1, and an emergency brake diaphragm 6 is provided between the emergency brake diaphragm 6 and the working diaphragm 2 for driving the working diaphragm. 2 curved working chamber 7, an emergency braking chamber 8 for driving the emergency braking diaphragm 6 to bend is provided between th...

Embodiment 2

[0048] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the emergency brake control valve 20 is driven by the emergency brake button 24, and the parking brake valve 21 is driven by the parking brake button 25, so that Improve the convenience of operation, such as Figure 9 shown.

[0049] In this embodiment, the parking brake control valve 21 includes a first valve seat 26, a first gas channel 27 is provided inside the first valve seat 26, and one end of the first gas channel 27 passes through a first pipeline 32 It communicates with the emergency air tank 18, and the middle part of the first gas passage 27 is provided with a blocking valve plate 28 for controlling on-off, the blocking valve plate 28 is made of rubber, and the blocking valve plate 28 is controlled by the first The shaft 29 is driven to move along, and the moving direction of the blocking valve plate 28 is perpendicular to the flow direction of the first gas passage 27. One end of ...

Abstract

The invention relates to an efficient braking system based on a heavy-duty truck and a working method of the efficient braking system. The efficient braking system comprises a shell, a working diaphragm located in the shell and a push rod driven by the working diaphragm and extending out of an opening of the shell; an emergency braking diaphragm used for driving the push rod to extend out of the opening of the shell is arranged at the side, away from the push rod, of the working diaphragm; a working cavity used for driving the working diaphragm is arranged between the emergency braking diaphragm and the working diaphragm; and an emergency braking cavity used for driving the emergency braking diaphragm is arranged between the emergency braking diaphragm and the shell; a locking mechanism is arranged in the shell, a spring is arranged between the driving end of the locking mechanism and the working diaphragm, and when the spring pushes the driving end of the locking mechanism to move in the extending direction of the push rod, the locking mechanism fixes the push rod. The system is reasonable in design, the push rod is locked by designing the locking structure, the push rod can be conveniently maintained at a certain position, and the braking stability effect is greatly improved.

Description

Technical field: [0001] The invention belongs to the technical field of automobile braking, and in particular relates to a high-efficiency braking system based on heavy-duty trucks and a working method thereof. Background technique: [0002] When heavy-duty vehicles are running, major accidents often occur due to braking problems, usually due to sudden failure of the brakes. The pneumatic braking system is the most commonly used braking system for heavy-duty fuel vehicles. As the requirements for braking performance increase, the braking system should also reduce the driver's work intensity as much as possible. At present, most of the control devices for pneumatic braking It is composed of air pressure control components such as brake pedal mechanism and brake valve. Heavy-duty vehicles or vehicles that often drive in mountainous areas need to brake in time due to unknown dangers, so an efficient emergency braking system is needed. Most of the researches in this field use c...
