Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an oil brake tee. Background Art

[0002] The oil brake tee is a mechanical component whose main function is to connect multiple components in the brake system and circulate the brake oil. Through the oil brake tee, the brake oil can flow freely in the brake system, so that the vehicle can achieve the effect of braking or stopping.

[0003] For example, the Chinese utility model with publication number CN216805405U is a hydraulic automobile brake booster device, which plays a certain supporting role through the setting of the sealing structure and the supporting structure. At the same time, when the sliding valve block and the booster piston are moving, the fixed pipe and the connecting pipe in the supporting structure are close to and away from each other, the sleeve pipe and the limit column are close to and away from each other at the same time, and the support spring is stretched and compressed to support the outer lip and the inner lip of the sealing ring, so that the sealing ring is not easily squeezed and deformed to produce gaps, and the booster device is not easy to leak, which greatly improves the usability of the device. However, such a structure still has the following significant defects:

[0004] 1. During the assembly process, some air may remain inside the power assist device and fail to be completely discharged, which may have a negative impact on the braking performance;

[0005] 2. During the braking process, the driver needs to use a lot of force to step on the pedal to brake. The operation intensity is high, which is not conducive to timely braking of the vehicle and is prone to fatigue driving and safety accidents;

[0006] 3. Long-term use of brake fluid without replacement will cause impurities to accumulate inside the three-way valve. These impurities will degrade the protective additives in the brake fluid, which will in turn cause rust and corrosion inside the three-way valve, significantly shortening the service life of the three-way valve. Summary of the invention

[0007] The utility model aims to solve one of the technical problems existing in the prior art.

[0008] The present application provides an oil brake tee, comprising:

[0009] Oil brake tee, piston, fixing hole;

[0010] Also includes:

[0011] A No. 1 bleed screw, which is arranged at the bottom end of the oil brake tee;

[0012] A No. 2 air bleed screw is arranged on the side of the oil brake tee close to one end of the fixing hole.

[0013] Also includes:

[0014] An oil outlet component, which is used to evenly distribute the brake oil;

[0015] An oil inlet component is connected with the oil outlet component in cooperation with the oil outlet component.

[0016] The oil outlet parts include:

[0017] Oil outlet holes, which are arranged on both sides of one end of the oil outlet component provided with the fixing hole;

[0018] The oil outlet inner cavity is arranged inside the oil outlet component and is communicated with the oil outlet hole.

[0019] The oil inlet components include:

[0020] An oil inlet hole, which is arranged at the bottom end of the oil inlet component;

[0021] The oil inlet inner cavity is arranged inside the oil inlet component and is communicated with the oil inlet hole.

[0022] The radius of the oil inlet inner cavity is greater than the radius of the oil outlet inner cavity.

[0023] Also includes:

[0024] A sealing structure, which is arranged on the piston;

[0025] A connecting structure is used to connect the oil outlet component with the oil inlet component.

[0026] The sealing structure includes:

[0027] A mounting groove, which is arranged on the piston;

[0028] An annular airbag is arranged in the mounting groove.

[0029] The annular airbag is made of high polymer material polytetrafluoroethylene.

[0030] The connection structure includes:

[0031] An internal thread, which is arranged at an end of the oil inlet cavity away from the oil inlet hole;

[0032] The external thread is arranged at an end of the oil outlet component away from the fixing hole.

[0033] The oil outlet component and the oil inlet component are made of stainless steel.

[0034] The beneficial effects of the utility model are as follows:

[0035] 1. By setting the No. 1 bleed screw and the No. 2 bleed screw, the air inside the oil brake tee can be easily discharged to prevent the subsequent impact on its braking ability;

[0036] 2. The setting of the annular airbag can effectively reduce friction and further improve the braking effect. The setting of the oil outlet cavity and the oil inlet cavity can achieve the effect of secondary pressurization, so that the brake oil can generate greater braking force under the same stroke, improving the problem that the driver needs to use greater force to step on the pedal;

[0037] 3. Through the setting of the connection structure, the oil brake tee is divided into two parts: the oil outlet part and the oil inlet part. This is not only easy to disassemble, but also convenient for clearing the deposits formed by the long-term failure to replace the brake oil in the oil outlet cavity and the oil inlet cavity. The operation is simple and labor-saving. By using stainless steel material, its service life is significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0047] In the following, in conjunction with the accompanying drawings, an oil brake tee provided in an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0048] Embodiment 1:

[0049] like Figures 1 to 4 As shown, an embodiment of the present application provides an oil brake tee, including an oil brake tee 1, a piston 2, and a fixing hole 3; it also includes: a No. 1 air bleed screw 41, which is arranged at the bottom end of the oil brake tee 1; a No. 2 air bleed screw 42, which is arranged on the side of the oil brake tee 1 close to one end of the fixing hole 3.

[0050] Furthermore, an oil brake tee also includes an oil outlet component 5, which is used to evenly distribute the brake oil; and an oil inlet component 6, which is connected to the oil outlet component 5 in cooperation.

[0051] Furthermore, the oil outlet component 5 includes oil outlet holes 51 , which are arranged on both sides of the end of the oil outlet component 5 provided with the fixing hole 3 ; and an oil outlet cavity 52 , which is arranged inside the oil outlet component 5 and communicated with the oil outlet holes 51 .

[0052] Furthermore, the oil inlet component 6 includes an oil inlet hole 61 , which is arranged at the bottom end of the oil inlet component 6 ; and an oil inlet inner cavity 62 , which is arranged inside the oil inlet component 6 and communicated with the oil inlet hole 61 .

[0053] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the oil brake tee 1 is divided into two parts, an oil outlet component 5 and an oil inlet component 6. When installing the oil brake tee 1, the oil brake tee 1 is fixed to the vehicle through the fixing hole 3 at the top of the oil outlet component 6 and the threaded connection. An oil inlet hole 61 is provided at the center position of the bottom end of the oil inlet component 6. The oil inlet hole 61 is connected to the brake master cylinder. Two oil outlet holes 51 are provided on both sides of one end of the oil outlet component 5 with the fixing hole 3. The two oil outlet holes 51 are respectively connected to the brake sub-cylinders, and the brake sub-cylinders are used to provide braking force to the brake pads. After the oil brake tee 1 is fixed, the staff first adds brake oil into the oil outlet inner cavity 52, puts the piston 2 into the oil outlet inner cavity 52, and then connects the oil outlet component 5 to the oil inlet component 6. Start by adding brake oil to the oil inlet cavity 62 through the oil inlet hole 61, so that the inside of the oil inlet cavity 62 and the oil outlet cavity 52 are filled with brake oil except for the part between the piston 2. After filling, start exhausting. First unscrew the No. 1 bleed screw 41, and then step on the brake hard until the brake oil sprays out. Then tighten the No. 1 bleed screw 41 again, which can effectively prevent oil leakage during subsequent use. In this exhaust process, the air between the piston head of the piston 2 near the oil inlet hole 61 and the oil inlet hole 61 can be exhausted to prevent the air from affecting its braking effect. Similarly, the No. 2 bleed screw 42 is exhausted to exhaust the air between the piston head of the piston 2 near the oil outlet hole 51 and the oil outlet hole 51. At this time, the oil brake tee is installed;

[0054] Embodiment 2:

[0055] like Figures 1 to 5 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the radius of the oil inlet cavity 62 is also greater than the radius of the oil outlet cavity 52 .

[0056] Furthermore, an oil brake tee also includes a sealing structure 7, which is arranged on the piston 2; and a connecting structure 8, which is used to connect the oil outlet component 5 with the oil inlet component 6.

[0057] Furthermore, the sealing structure 7 includes a mounting groove 71 , which is disposed on the piston 2 ; and an annular airbag 72 , which is disposed in the mounting groove 71 .

[0058] Furthermore, the annular airbag 72 is made of a polymer material, polytetrafluoroethylene.

[0059] In this embodiment of the present application, due to the adoption of the above-mentioned structure, five mounting grooves 71 are respectively arranged at equal intervals on the two piston heads of the piston 2, and an annular airbag 72 is fixed inside the mounting groove 71. The annular airbag 72 can effectively reduce the direct contact area between the piston 2 and the oil inlet cavity 62 and the oil outlet cavity 52. ​​The annular airbag 72 always maintains an airtight cooperation with the oil inlet cavity 62 and the oil outlet cavity 52, effectively preventing the leakage of the brake fluid. The annular airbag 72 adopts a polymer material polytetrafluoroethylene, which has strong lubrication performance and low friction coefficient, and can effectively reduce the friction between the annular airbag 72 and the oil inlet cavity 62 and the oil outlet cavity 52, so that the braking effect is further improved. The radius of the oil inlet cavity 62 is greater than the radius of the oil outlet cavity 52, so that it produces a secondary pressurization effect. The brake oil can generate a greater braking force under the same pedal stroke, effectively reducing the force required for the driver to step on the brake pedal, and improving the convenience and safety of driving.

[0060] Embodiment 3:

[0061] like Figures 1 to 4 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the connecting structure 8 includes an internal thread 81, which is arranged at an end of the oil inlet cavity 61 away from the oil inlet hole 61; and an external thread 82, which is arranged at an end of the oil outlet component 5 away from the fixing hole 3.

[0062] Furthermore, the oil outlet component 5 and the oil inlet component 6 are made of stainless steel.

[0063] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the oil outlet component 5 and the oil inlet component 6 are connected together by the external thread 82 and the internal thread 81, which is not only easy to disassemble, but also convenient for clearing the deposits formed by the long-term non-replacement of the brake oil in the oil outlet cavity 52 and the oil inlet cavity 62, and the operation is simple and labor-saving; the oil inlet component 6 and the oil outlet component 5 are made of stainless steel material, and the stainless steel material has good high temperature resistance and corrosion resistance, can effectively resist rust and corrosion, and significantly increase the service life of the oil brake tee.
