TECHNICAL FIELD

[0001] The utility model relates to brake auxiliary device technical field, concretely is a kind of automobile hydraulic brake auxiliary device. BACKGROUND

[0002] In the development history of automobile, brake system is always the core key concerning driving safety. Early automobile brake mainly relies on simple mechanical brake structure, and driver needs to rely on the greater physical force of oneself to step on brake pedal, and brake is directly driven to work by mechanical connecting rod. However, with the rapid progress of automobile industry, the speed, mass and driving condition of vehicle are increasingly complex and diversified, and traditional mechanical brake mode exposes many drawbacks.

[0003] On the one hand, simply rely on manpower to step on brake pedal, and driver is often difficult to apply enough brake force instantaneously in emergency braking, especially for some small-strength drivers, such as old people, women and other groups, which makes brake response time prolong, brake distance greatly increase, and greatly improves the risk of traffic accident.

[0004] On the other hand, frequent high-intensity brake operation is easy to make driver tired, not only affects driving experience, but also further weakens the reaction ability and concentration of driver in subsequent driving process. At the same time, in some special road conditions, such as long downhill, high-speed driving needs emergency braking, and traditional brake system cannot quickly and effectively dissipate heat, and brake is easy to overheat, which leads to sharp decline of brake efficiency, that is, common "brake failure", which seriously threatens the life safety of vehicle and driver.

[0005] To cope with these problems, automobile hydraulic brake auxiliary device emerges as the times require. Hydraulic technology can generate powerful pressure by using hydraulic pump when driver steps on pedal, and auxiliary brake effect is enhanced, which greatly reduces the operation burden of driver, and makes brake more rapid and powerful.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] like Figures 1-3 As shown, an embodiment of the present invention provides an automotive hydraulic braking auxiliary device, comprising a brake disc 1 and a brake 2 mounted on the brake disc 1;

[0026] As a key rotating component of the braking system, the brake disc 1 is usually made of alloy steel, which has high strength and wear resistance. It is fixedly connected to the wheel and rotates with the wheel.

[0027] During braking, the brake disc 1 rubs against the fixed brake pad 28 and the moving brake pad 211, converting the vehicle's kinetic energy into heat energy, thereby achieving vehicle deceleration or stopping.

[0028] The brake 2, including the protective cover 21, is generally made of metal and is installed on the outside of the brake 2. Its shape is adapted to the overall structure of the brake 2 and plays a protective role.

[0029] To prevent dust, water, and debris from entering the brake 2, thus avoiding damage to the internal structure and extending the service life of the brake 2.

[0030] The mounting plate is fixedly connected to one end of the protective cover 21. It is usually a flat plate structure with a certain strength and rigidity, and has mounting holes for mounting components such as hydraulic cylinder 22.

[0031] Provides a mounting base for components such as hydraulic cylinder 22, ensuring accurate relative positions between components and enabling brake 2 to work stably.

[0032] The hydraulic cylinder 22 is embedded in the mounting plate and consists of a cylinder body, piston, piston rod, and other components. It is driven by the pressure of hydraulic oil to move the piston rod linearly. The hydraulic cylinder 22 is electrically connected to a pressure sensor, which can monitor the hydraulic pressure inside the cylinder in real time.

[0033] As the power source of the brake auxiliary device, the hydraulic energy is converted into mechanical energy to provide auxiliary power for the braking process and push the connecting piece 23 to move.

[0034] The connecting piece 23 is rotatably connected with a rotating shaft 24 at its center, and the two ends are rotatably connected with the output end of the hydraulic cylinder 22, and the top is rotatably connected with the pull rod 29.

[0035] The linear motion of the hydraulic cylinder 22 is converted into the swinging motion of the pull rod 29, which plays a role in force transmission and motion conversion, and the gap at both ends ensures that the pull rod 29 is always in a horizontal state, making the braking action more stable.

[0036] The rotating shaft 24 is usually in a cylindrical structure and is rotatably connected with the fixed part 25 to provide rotational support for the connecting piece 23.

[0037] As the rotating center of the connecting piece 23, it ensures that the connecting piece 23 can rotate flexibly and effectively transmit force.

[0038] The fixed part 25 is fixedly connected with the fixed disc 26 and has certain strength and stability, which is used for installing and fixing the rotating shaft 24.

[0039] It provides reliable support for the rotating shaft 24 and ensures the stability of the rotating process of the connecting piece 23, ensuring the normal operation of the entire brake mechanism.

[0040] The fixed disc 26 is fixedly connected with the mounting plate through two columns 27, and the disc surface is provided with a clamping groove for clamping the fixed brake pad 28.

[0041] It provides a position for installing and fixing the fixed brake pad 28, ensures the accurate relative position of the fixed brake pad 28 and the brake disc 1, and connects with the mounting plate through the column 27 to enhance the stability of the entire structure.

[0042] The column 27 is generally in a columnar structure, and the two ends are fixedly connected with the mounting plate and the fixed disc 26 respectively.

[0043] It plays a role in connecting and supporting the fixed disc 26, and ensures the fixed relative position between the fixed disc 26 and the mounting plate, making the structure of the brake 2 more stable.

[0044] The fixed brake pad 28 is composed of friction material and a bottom plate and is clamped and installed on the fixed disc 26 in contact with the left surface of the brake disc 1.

[0045] When braking, it produces friction with the brake disc 1 to generate braking force and slow down or stop the vehicle.

[0046] One end of the pull rod 29 is rotatably connected with the top of the connecting piece 23, and the other end is fixedly sleeved on the movable disc 210 and clamped and sleeved on the top of the fixed disc 26.

[0047] The movement of the connecting piece 23 is transmitted to the moving disc 210, so that the moving disc 210 can move with the movement of the connecting piece 23, and the braking action is realized.

[0048] The moving disc 210 is located on the right side of the brake disc 1, and is sleeved and fixed with one end of the pull rod 29. A clamping groove for clamping the moving brake pad 211 is arranged on the disc surface.

[0049] Under the action of the pull rod 29, the moving brake pad 211 moves towards the brake disc 1, and contacts the brake disc 1, and cooperates with the fixed brake pad 28 to realize clamping and braking of the brake disc 1.

[0050] The moving brake pad 211 is similar to the fixed brake pad 28, and is composed of friction material and a bottom plate, and is clamped and installed on the moving disc 210 through the clamping groove.

[0051] When braking, the moving brake pad 211 generates friction with the brake disc 1, cooperates with the fixed brake pad 28, generates sufficient braking force, and makes the vehicle decelerate or stop.

[0052] When the automobile needs to brake, the driver steps on the brake pedal, the pressure of the hydraulic system associated with the brake pedal changes, and then drives the hydraulic cylinder 22 in the device to work. The output end of the hydraulic cylinder 22 pushes the connecting piece 23 to rotate around the rotating shaft 24, and the rotating shaft 24 is installed on the fixed part 25, and the fixed part 25 is connected with the fixed disc 26 to ensure the stability of the whole structure. When the connecting piece 23 rotates, the pull rod 29 connected at the top is moved, one end of the pull rod 29 is sleeved and fixed on the moving disc 210, so that the moving disc 210 moves towards the brake disc 1. At this time, the fixed brake pad 28 clamped and installed on the fixed disc 26 originally contacts the left side surface of the brake disc 1, and the moving brake pad 211 clamped on the moving disc 210 is pressed tightly on the brake disc 1 from the right side under the action of the moving disc 210. Through the friction force generated between the moving brake pad 211 and the fixed brake pad 28 and the brake disc 1, the brake disc 1 is braked, and then the wheel is decelerated or stopped. At the same time, the pressure sensor electrically connected with the hydraulic cylinder 22 monitors the hydraulic pressure in the hydraulic cylinder 22 in real time, and transmits the pressure signal to the electronic control unit of the automobile, so as to monitor and control the whole braking process.

[0053] As shown in Figure 2 In some embodiments, the two ends of the connecting piece 23 are provided with a certain gap, so that the pull rod 29 is always in a horizontal state; in the working process of the automobile hydraulic brake auxiliary device, the connecting piece 23 is a key component for connecting the hydraulic cylinder 22 and the pull rod 29, and needs to accurately transmit the force output by the hydraulic cylinder 22 to the pull rod 29. When the two ends of the connecting piece 23 are provided with a certain gap, the additional lateral force on the pull rod 29 caused by the slight angle deviation in the movement process of the connecting piece 23 can be avoided. In this way, the pull rod 29 can move smoothly in the horizontal direction, so as to effectively transmit the force to the moving disc 210, and ensure the smooth progress of the braking action.

[0054] As shown in Figure 2 some embodiments, the fixed disc 26 is fixedly connected to the mounting plate through two upright columns 27; the fixed brake pad 28 is installed on the fixed disc 26, and a large force is generated by the friction between the fixed brake pad 28 and the brake disc 1 during braking. The fixed connection of the fixed disc 26 to the mounting plate through the two upright columns 27 can provide stable support for the fixed disc 26, ensure that the fixed disc 26 does not displace or shake during braking, and thus ensure the accurate relative position of the fixed brake pad 28 and the brake disc 1, making the braking effect more stable and reliable.

[0055] As shown in Figure 3 some embodiments, the fixed brake pad 28 contacts the left side surface of the brake disc 1; during automobile braking, the brake disc 1 rotates with the wheel. The fixed brake pad 28 contacts the left side surface of the brake disc 1, and when the braking instruction is issued, the hydraulic cylinder 22 pushes the related components to act, driving the movable disc 210 and the movable brake pad 211 thereon to approach the brake disc 1 from the right side. At this time, the fixed brake pad 28 and the movable brake pad 211 act like a pair of “claws” to tightly clamp the brake disc 1 from both sides. Through the frictional force generated between the brake disc 1, the kinetic energy of the vehicle is converted into heat energy, thereby achieving the braking effect and slowing down or stopping the vehicle. This double-sided braking method can generate greater braking force than single-sided braking, effectively shorten the braking distance, and improve the driving safety.

[0056] As shown in Figure 3 some embodiments, the pull rod 29 is clamped and sleeved at a top portion of the fixed disc 26; the clamping and sleeving of the pull rod 29 at the top portion of the fixed disc 26 provides accurate guidance for the movement of the pull rod 29.

[0057] In some embodiments, the hydraulic cylinder 22 is electrically connected to a pressure sensor, and the pressure sensor is electrically connected to the electronic control unit of the automobile, for real-time monitoring of the hydraulic pressure in the hydraulic cylinder 22 and transmitting the pressure signal to the electronic control unit; the combination of the pressure sensor and the electronic control unit enables the automobile braking system to have intelligent features. The braking pressure can be automatically adjusted according to the actual situation without manual intervention by the driver, improving the convenience and safety of driving;

[0058] Through real-time monitoring and accurate control of the hydraulic pressure, damage to the braking components due to long-term bearing of excessively high or low pressure can be avoided, the service life of the hydraulic cylinder 22, the braking pipeline, the brake pad, and other components is prolonged, and the maintenance cost is reduced;

[0059] The electronic control unit can determine whether the brake system has a fault according to the signal transmitted by the pressure sensor.

[0060] Finally, it should be noted that: the above only for the preferred embodiments of the utility model have, and do not for limiting the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
