Description

Technical Field

[0001] The utility model provides an automobile brake assembly structure, which relates to the technical field of automobile brakes. Background Art

[0002] Automobile brakes are the braking devices of automobiles. Brakes used in automobiles are almost all friction type, which can be divided into two categories: drum type and disc type. The rotating element in the friction pair of drum brakes is the brake drum, whose working surface is a cylindrical surface; the rotating element of disc brakes is a rotating brake disc, whose end surface is the working surface. Automobile brakes refer to the components that produce forces that hinder the movement or movement trend of the vehicle, which also include devices in the auxiliary braking system.

[0003] In the existing automobile brakes, human power alone cannot give the brakes enough force for braking. Generally, air pressure or hydraulic pressure is used to assist in pushing the internal parts of the brakes to move, thereby achieving the purpose of braking. In the existing pneumatic auxiliary brakes, it is necessary to keep one side of the brake in a vacuum and the other side at the same air pressure as the external air pressure. When braking, the vacuum area is blocked, and the side with normal air pressure is recessed toward the side of the vacuum area, thereby achieving the operation of the brake. However, when the existing brakes are in use, the vacuum area may not reach a complete vacuum, causing the driver to use greater force for braking, or even unable to brake, which is easy to cause safety accidents in emergency situations.

[0004] Therefore, it is necessary to provide an automobile brake assembly structure capable of detecting the vacuum state in the brake. Utility Model Content

[0032] See also Figure 4As shown, the brake master cylinder assembly includes an oil pump housing 11 installed on the side of the power-assisting disc 1 away from the mounting tube 101 by bolt connection, a first piston column 14 is slidably arranged in the oil pump housing 11, a first rubber block 13 for sealing and isolating the space is sleeved on the side of the first piston column 14 close to the power-assisting disc 1, a guide block 12 is slidably arranged in the oil pump housing 11, a fourth elastic member 15 for resetting is wound around the first piston column 14, a second piston column 17 is slidably arranged in the oil pump housing 11, a second rubber block 16 for sealing and isolating the space is sleeved on the side of the second piston column 17 close to the first piston column 14, a fifth elastic member 18 for resetting is wound around the second piston column 17, a first cavity 1501 is formed between the first piston column 14 and the second piston column 17, a second cavity 1502 is formed on the side of the second piston column 17 away from the first piston column 14, and the oil pump housing 11 is provided with a plurality of piston rods 17, wherein the plurality of piston rods 17 are ... The top of the body 11 is connected and communicated with a brake oil tank 21 for supplying brake oil. The elastic coefficient of the fourth elastic member 15 is smaller than the elastic coefficient of the fifth elastic member 18 to ensure that the fourth elastic member 15 pushes the second piston column 17 to compress the fifth elastic member 18 after being fully compressed, so that the two sets of brakes can operate independently. Initially, one through port of the brake oil tank 21 and the oil pump housing 11 is communicated with the first cavity 1501, and the other through port is communicated with the second cavity 1502. A mounting cover 23 is threadedly provided on the top of the brake oil tank 21.

A limiting rod 19 is fixedly connected between the inner wall of the oil pump housing 11 and an oil inlet plate 20 by welding, and the second piston column 17 is slidably connected to the limiting rod 19.

[0033] See also Figure 1 As shown, the two oil outlets of the oil pump housing 11 are respectively connected and communicated with a first gasoline pipe 43 and a second gasoline pipe 4301 , and the first gasoline pipe 43 and the second gasoline pipe 4301 are both communicated with the brake 44 .

[0034] When braking is required, the driver steps on the brake pedal, and the brake pedal pushes the mounting ear plate 2 to make the push rod 201 push the first ejector pin 4 to slide into the mounting tube 101, and the first ejector pin 4 pushes the push plate 5 through the first elastic member 6. When the push plate 5 is blocked by the mounting tube 101, the first elastic member 6 is compressed and deformed by force, and the first ejector pin 4 penetrates the push plate 5 to push the second ejector pin 7. The second ejector pin 7 pushes the blocking ring 8 to slide through the second elastic member 801, so that the blocking ring 8 closes the vent 102. At this time, the inside of the power assist disc 1 is divided into two vacuum areas by the diaphragm 105. As the second ejector pin 7 continues to push, the blocking ring 8 is protruded from the outlet of the vent 102 of the mounting tube 101. The structure blocks, and the second ejector pin 7 pushes the valve piston 9. At this time, the second elastic member 801 is compressed and deformed to generate a gap between the barrier ring 8 and the valve piston 9. At this time, the external air pressure enters the space on one side of the diaphragm 105 in the power-assisting disc 1 through this gap. At this time, the left side of the diaphragm 105 in the power-assisting disc 1 is the atmospheric pressure area, and the other side of the diaphragm 105 in the power-assisting disc 1 is the vacuum negative pressure area. The diaphragm 105 is assisted to bend to the right by the air pressure difference. At the same time, the valve piston 9 passes through the limit ring 901 to push the rubber reaction disc 1002, thereby making the third ejector pin 1001 slide to the outside of the power-assisting disc 1. At this time, the third elastic member 10 is compressed and deformed; the brake oil in the brake oil tank 21 is introduced into the brake oil tank 21 through the two oil inlet plates 20. The third ejector pin 1001 slides into the oil pump housing 11, and then pushes the guide block 12 to push the first piston rod 14 to slide into the oil pump housing 11. At this time, the first piston rod 14 slides toward the second piston rod 17 and compresses the fourth elastic member 15. The space of the first cavity 1501 is gradually compressed. When the first piston rod 14 passes over the oil inlet plate 20, the brake oil in the first cavity 1501 overflows into the first gasoline pipe 43 through the oil outlet plate 22 to drive the brake 44 of the front wheel to brake. When the fourth elastic member 15 is compressed to the limit, the first piston rod 14 passes through the fourth elastic member 15 The second piston rod 17 is pushed to compress the fifth elastic member 18. At this time, the space of the second cavity 1502 is gradually compressed. After the second piston rod 17 passes over the oil inlet plate 20, the brake oil in the second cavity 1502 overflows into the second gasoline pipe 4301 through the oil outlet plate 22 to drive the brake 44 of the rear wheel for braking; when the vacuum area on the rear side of the diaphragm 105 in the power-assisting disc 1 has not reached a complete vacuum, at this time, the air contacts the sensing module 26 of the vacuum gauge 24 through the air guide pipe 25. The sensing module 26 sends a signal to the vehicle to prompt the driver. The driver can connect the connecting pipe 104 to the vacuum pump to extract the air in the power-assisting disc 1 to form a vacuum area, which makes auxiliary braking easier.

[0036] When it is necessary to add brake oil to the brake oil tank 21, the servo motor 29 is started to drive the eccentric wheel 30 to rotate. The eccentric wheel 30 pulls the guide rod 3002 through the connecting rod 3001, so that the guide rod 3002 drives the piston plate 31 to slide downward in the mounting cylinder 28. At this time, the air pressure in the mounting cylinder 28 becomes low, and the brake oil is pumped into the mounting cylinder 28 through the first guide pipe 33. At this time, the water inlet check valve 3202 is open and the water outlet check valve 3201 is closed. When the piston plate 31 slides upward in the mounting cylinder 28, the water inlet check valve 3202 is closed, and at the same time, the piston plate 31 pushes the brake oil to automatically open the water outlet check valve 3201, and the brake oil enters the brake oil tank 21 through the second guide pipe 34. This reciprocating process can replenish the brake oil in the brake oil tank 21.

At this time, the card ball 36 compresses the sixth elastic member 37 to make the card ball 36 detach from the connecting tube 104, and the mounting sleeve 35 can be removed from the connecting tube 104.
