Description

Technical Field

[0001] The utility model relates to the technical field of brake oil pipes, in particular to a front brake oil pipe with a long service life. Background Technique

[0002] The front brake oil pipe is a key component of the vehicle braking system. With the improvement of vehicle performance, the requirements for brake oil pipes are becoming increasingly strict. Traditional oil pipes have deficiencies in high temperature resistance, high pressure resistance, and corrosion resistance, affecting braking performance and safety. New technologies aim to optimize materials and structures to improve the reliability and service life of brake oil pipes;

[0003] The existing front brake oil pipe consists of an inner pipe, a reinforcing layer, and an outer protective layer. The inner pipe is made of oil-resistant rubber and special plastics, directly contacting the brake fluid and ensuring its smooth transmission. The reinforcing layer is mostly made of steel wire braiding or winding to provide strength to withstand the high pressure during braking. The outer protective layer is often rubber or plastic, playing a protective role. Its principle is that when the brake pedal is depressed, the brake fluid is pressurized in the inner pipe and quickly and accurately transmitted through the oil pipe to the brake caliper, generating braking force to decelerate or stop the vehicle;

[0004] The existing front brake oil pipe cannot achieve quick splicing. When the oil pipe fails or is damaged, it is difficult to replace it quickly, increasing the maintenance time and cost. Therefore, a front brake oil pipe with a long service life is proposed to solve the above problems. Content of the Utility Model

[0031] Refer to Figures 1-3, an embodiment provided by the present utility model: a front brake brake oil pipe with a long service life, including a hose 1 for transmitting brake fluid. Sheaths 2 are sleeved on the outer peripheries of both the left and right ends of the hose 1. The two sheaths 2 are used to protect the hose 1 and enhance its wear resistance. Inner lining structures are arranged in both of the two sheaths 2, and the inner lining structures are used to enhance the protection performance of the sheaths 2. Both the left and right ends of the hose 1 are fixedly connected with second connectors 8, and the two second connectors 8 are used to connect the hose 1 with other structures. A first connector 6 is fixedly connected to the left end of one of the second connectors 8, and a third connector 9 is fixedly connected to the right end of the other second connector 8. The first connector 6 and the third connector 9 are used to connect the hose 1 to other brake brake mechanisms. Rubber wheels 7 are sleeved on the middle and right parts of the hose 1, and the two rubber wheels 7 are used to enhance the wear resistance of the hose 1. A sleeve 5 is sleeved on the left end of the hose 1, and the sleeve 5 connects and fixes the hose 1. A button 4 is slidably connected to the upper part of the sleeve 5. A spring 3 is sleeved on the outer periphery of the button 4, and the bottom of the spring 3 is fixedly connected to the top of the sleeve 5. The button 4 is used to control the locking structure inside the sleeve 5, and the spring 3 is used to reset the button 4. A push block 10 is fixedly connected to the bottom of the button 4, and the push block 10 is used to transmit the power of the button 4 to other structures. One end of a connecting rod 11 is rotatably connected to both the front and rear sides of the push block 10, and the other ends of the two connecting rods 11 are rotatably connected to a sliding block 12. When the push block 10 moves downward, it can push the lower ends of the two connecting rods 11 to open and drive the two sliding blocks 12 to move in the reverse direction to release the locking structure. Chutes 13 are opened on both the front and rear sides of the left end of the hose 1, and the two sliding blocks 12 are both slid in the two chutes 13. The two sliding blocks 12 are engaged inside the two chutes 13 to splice and fix the hose 1. Holes are opened at the upper ends of the first connector 6 and the third connector 9, and the holes are used to sleeved the first connector 6 and the third connector 9 on the outer periphery of the brake brake structure. Zinc-nickel coatings are coated on the surfaces of the first connector 6 and the third connector 9, and the zinc-nickel coatings have strong wear resistance and corrosion resistance. The hose 1 and the two rubber wheels 7 are both made of nitrile rubber, and nitrile rubber has strong oil resistance and corrosion resistance, enhancing the service life of the hose 1.

[0032] Refer to Figure 1 and Figure 3 , the inner lining structure includes a first inner lining layer 14, and the first inner lining layer 14 is lined inside the sheath 2. A second inner lining layer 15 is lined inside the first inner lining layer 14. The first inner lining layer 14 is used to enhance the strength of the two sheaths 2 and prevent them from breaking. The first inner lining layer 14 is woven by steel wires, and the steel wires can enhance the compressive capacity of the two sheaths 2 and improve the fatigue strength.

[0033] Working principle: Sheath joint one 6 and joint three 9 around the outer periphery of the braking structure. Press the button 4, and the push block 10 connected to the lower part of the button 4 moves downward, which can drive the two connecting rods 11 to move downward. The lower ends of the two connecting rods 11 can push the two push blocks 10 connected to the lower ends to open. Insert the hose 1 into the sleeve 5. Release the button 4, and the spring 3 resets the button 4 and pushes it upward, which can drive the push block 10 and the two connecting rods 11 connected to the push block 10 to move upward. The two connecting rods 11 can drive the two push blocks 10 to contract and get stuck inside the two sliding grooves 13. The spring 3 prevents the button 4 and its connected structure from moving, so that the hose 1 is clamped inside the sleeve 5, completing the rapid splicing of the pipeline.
