Description

Technical Field

[0001] The utility model belongs to the technical field of brake calipers, in particular to a hydraulic-electric hybrid integrated brake caliper. Background Art

[0002] With the development of electronic technology and the Internet, cars have become more intelligent. In the field of automotive braking technology, brakes have gradually evolved from traditional mechanical to integrated electronic. In order to meet the needs of different consumer groups, car types have become more diverse, so there is an urgent need for a hydraulic-electric hybrid integrated brake caliper that can be used in a variety of models.

[0003] When a car is driving, the braking force required at different speeds is also different. Compared with traditional hydraulic brakes, electronic brakes have a faster response speed and a more linear pedal feel, which can improve the comfort of manual driving. However, electronic brakes are affected by the battery and may affect the safety of driving braking. Therefore, we propose a hydraulic-electric hybrid integrated brake caliper to solve this problem. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the utility model provides a hydraulic-electric hybrid integrated brake caliper, which can effectively solve the problems of the prior art.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The utility model is a hydraulic-electric hybrid integrated brake caliper, comprising a caliper body and an installation chamber body provided on the upper end surface of the caliper body, and also comprising:

[0007] The guide cylinder is symmetrically arranged inside the installation bin;

[0008] The movable plate is symmetrically arranged inside the installation bin;

[0009] The hydraulic assembly is arranged inside the movable plate to increase the braking force and ensure the braking efficiency at the critical moment.

[0010] Furthermore, a sliding pin hole is provided on the side surface of the movable plate, and the sliding pin hole is slidably sleeved on the outside of the guide column.

[0011] Furthermore, the hydraulic assembly includes a cylinder cavity and a piston body. The cylinder cavity is linearly distributed and opened on the inner side of the movable plate, and the piston body is slidably engaged in the cylinder cavity.

[0012] Furthermore, a brake pad is installed on the inner side of the piston body, and the brake pads on both sides can be close to the middle brake disc.

[0013] Furthermore, oil filling ports are linearly arranged directly above the movable plate, and an oil pipeline is sealed above the oil filling ports. An oil inlet pipeline is arranged inside the movable plate, and the oil inlet pipeline is sealed to the upper oil filling port.

[0014] Furthermore, the other end of the oil inlet pipeline is sealed and connected with an oil release port, and the oil release port is located at the inner center of the cylinder cavity.

[0015] The utility model has the following beneficial effects:

[0016] When the automobile of the utility model brakes at high speed, the brake oil can be simultaneously introduced into the interior of the oil inlet pipe through the oil filling port through the external oil delivery pipeline, and then transported to the interior of the cylinder cavity from the oil release port through the oil inlet pipe. As the brake oil injected into the cylinder cavity increases, the piston body can apply greater force to the brake disc under the hydraulic pressure of the brake oil, thereby forming a better braking effect, which is adjusted according to the force of stepping on the pedal. When a certain force is stepped on, the intervention of the hydraulic component can greatly improve the braking efficiency. At the same time, when parking or driving at low speed, only the motor brake can be used, which can prevent safety problems of the automobile in the event of electronic brake failure, thereby making braking safer.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] See also Figure 1-4 As shown, the utility model is a hydraulic-electric hybrid integrated brake caliper, comprising a caliper body 1 and an installation chamber body 3 formed on the upper end surface of the caliper body 1, and also comprising:

[0026] The guide column 2 is symmetrically arranged inside the mounting chamber 3, and the movable plate 4 is symmetrically arranged inside the mounting chamber 3; a sliding pin hole 10 is opened on the side of the movable plate 4, and the sliding pin hole 10 is slidably sleeved on the outside of the guide column 2. Similar to the floating caliper method, the inner piston can be driven by an external motor to push the movable plate 4 close to the rotating brake disc. As the braking pressure increases, the contact force between the brake pad 8 and the brake disc will increase. Due to the reaction force, the caliper body 1 will move in the axial direction along the guide column 2. This action enables the outer friction plate to contact the brake disc and apply pressure for braking;

[0027] A hydraulic component is arranged inside the movable plate 4 to increase the braking force and ensure the braking efficiency at critical moments. The hydraulic component includes a cylinder chamber 6 and a piston body 7. The cylinder chamber 6 is linearly distributed and opened on the inner side of the movable plate 4. The piston body 7 is slidably engaged in the cylinder chamber 6. Brake pads 8 are installed on the inner side of the piston body 7, and the brake pads 8 on both sides can approach the middle brake disc. An oil filling port 5 is linearly distributed just above the movable plate 4, and an oil pipeline is sealed above the oil filling port 5. An oil inlet pipe 11 is arranged inside the movable plate 4, and the oil inlet pipe 11 is sealedly connected to the upper oil filling port 5. The other end of the oil inlet pipe 11 is sealedly connected to a release oil port 9, and the release oil port 9 is located at the central position inside the cylinder chamber 6. At a slower driving speed or parking situation, control can be achieved by relying solely on the electronic brake. At a faster speed, the brake oil can be simultaneously fed through the oil filling port 5 into the oil inlet pipe 11 through an external oil pipeline, and then delivered from the release oil port 9 to the cylinder chamber 6 through the oil inlet pipe 11. As the amount of brake oil injected into the cylinder chamber 6 increases, the piston body 7 can apply greater force to the brake disc under the hydraulic pressure of the brake oil, thereby achieving a better braking effect, which can be adjusted according to the force of stepping on the pedal. When a certain force is applied, the intervention of the hydraulic component can greatly improve the braking efficiency. At the same time, when parking or driving at a low speed, only the motor brake can be used to prevent safety problems of the car in the event of electronic brake failure, thereby making braking safer.

[0028] Working principle: The above device is the same as the floating caliper. When the inner piston is driven by an external motor to push the moving plate 4 close to the rotating brake disc, the contact force between the brake pad 8 and the brake disc will increase as the braking pressure increases. Due to the reaction force, the caliper body 1 will move in the axial direction along the guide column 2. This action enables the outer friction pad to contact the brake disc and apply pressure for braking;

[0029] When braking at high speed, the brake oil can be simultaneously introduced into the oil inlet pipe 11 through the external oil pipeline through the oil filling port 5, and then transported to the inside of the cylinder chamber 6 from the release oil port 9 through the oil inlet pipe 11. As the brake oil injected into the cylinder chamber 6 increases, the piston body 7 can apply greater force to the brake disc under the hydraulic pressure of the brake oil, thereby forming a better braking effect, and adjusting according to the force of stepping on the pedal. When a certain force is stepped on, the intervention of the hydraulic component can greatly improve the braking efficiency. At the same time, when parking or driving at low speed, only the motor brake can be used to prevent safety problems of the car in the event of electronic brake failure, making braking safer.

[0030] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
