Description

Technical Field

[0001] The invention belongs to the technical field of brake pads, and in particular relates to a brake pad installation structure capable of quickly fitting to a brake drum. Background Art

[0002] Brake pads are a crucial component of a car's braking system, applying pressure to the wheels to slow or stop the vehicle. They are typically made of friction material and generate friction when in contact with the brake drum, thereby braking the wheel. The brake drum is the rotating component connected to the wheel, creating a tight interface with the brake pads, enabling them to properly apply pressure to the wheel.

[0003] However, when the brake drum is subjected to excessive wear or overheating, it may deform, which may cause the brake pad to not fit tightly against the brake drum, resulting in poor practicality. This phenomenon has become a problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0004] The purpose of the present invention is to provide a brake pad installation structure that can quickly fit the brake drum of the existing skidding device, so as to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a brake pad mounting structure that quickly fits the brake drum, comprising a brake drum shell, a brake pad mounting bracket being installed on the inner wall of the brake drum shell, a vehicle rotating shaft being provided on one side of the brake drum shell, an angle sensor being provided on one end of the vehicle rotating shaft, and an electronic control box being fixedly installed on the outer wall of the brake drum shell by welding.

[0006] The present invention further describes that the brake pad mounting frame is divided into two parts from the middle, and the brake pad body is slidably arranged between the two parts of the brake pad mounting frame;

[0007] A movable square block is fixed to one side of the brake pad body by welding, and a sliding guide column is slidably inserted into the inner wall of the movable square block. A mounting block is installed at one end of the sliding guide column, and the mounting block is fixed to the inner wall of the brake drum shell by welding.

[0008] The present invention further describes that a resistor is fixed to the outer wall of the sliding guide column by welding, and a conductive block is slidably sleeved on the outer wall of the sliding guide column. The inner wall of the conductive block contacts the resistor and forms a power-on circuit. One end of the two conductive blocks is connected to a wire, and a power supply is electrically connected between the two wires. The power supply is arranged in an electrical control box, and an ammeter is electrically connected between the power supply and the resistor. One side of the conductive block is fixed to the movable square block by welding.

[0009] The present invention further describes that a spring is connected between the installation block and the movable square block, and the spring is movably sleeved on the outside of the sliding guide column.

[0010] The present invention further states that the mounting structure employs the following braking force detection system:

[0011] It includes a braking force drawing module, a coordinate system establishment module, a braking force calculation module, an elastic force calculation module, and a displacement calculation module. The current measurement meter is electrically connected to the displacement calculation module, the displacement calculation module is electrically connected to the elastic force calculation module, the elastic force calculation module is electrically connected to the braking force calculation module, the displacement calculation module is electrically connected to the coordinate system establishment module, and the braking force drawing module is electrically connected to the coordinate system establishment module and the braking force calculation module.

[0013] The present invention is further described, comprising the following specific steps:

[0014] S1. When real-time monitoring of the braking force is performed, the power supply of the motor is turned on to rotate the shaft of the vehicle;

[0015] S2. When braking, the brake pads are moved toward the brake drum by external force. The brake drum exerts a squeeze, attraction, or repulsion on the brake pads, pushing each pad outward or inward, resulting in a slight displacement.

[0016] S3, detect the resistance of the resistor through the system;

[0017] S4. Draw a braking force cross-sectional diagram based on the current values ​​of the current measuring table corresponding to the circumferentially distributed brake pad body to obtain an intuitive rotor dynamic braking force distribution diagram;

[0018] S5. When the motor stops, a static braking force distribution diagram can be obtained according to the current size of the current measuring meter corresponding to the brake pad body.

[0019] The present invention further illustrates that in the above step S3, specifically: when the power supply is turned on, the resistor sheet and the conductive block form a power-on circuit, and when the brake pad body is displaced, the conductive block is driven to move, thereby changing the resistance of the resistor sheet connected to the power-on circuit, thereby affecting the current detected by the ammeter.

DETAILED DESCRIPTION

[0028] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0029] See also Figure 1-5The present invention provides a technical solution: a brake pad installation structure that quickly fits the brake drum, including a brake drum housing 8, a brake pad installation bracket 5 installed on the inner wall of the brake drum housing 8, a vehicle shaft provided on one side of the brake drum housing 8, an angle sensor 72 provided on one end of the vehicle shaft, an electric control box 4 fixedly installed on the outer wall of the brake drum housing 8 by welding, the electric control box 4 provides an installation position for the internal electrical components, and the angle sensor 72 measures the rotation angle of the vehicle shaft. When in use, the vehicle shaft rotates or stops to perform braking;

[0030] The brake pad mounting frame 5 is divided into two parts from the middle, and a brake pad body 241 is slidably arranged between the two parts of the brake pad mounting frame 5, and the braking effect is performed through the brake pad body 241;

[0031] The brake pad body 241 can attract inward or repel outward according to the direction of the reaction force between the current shaft and the brake pad mounting frame 5, so that the position can be adjusted intuitively according to the current direction of the reaction force;

[0032] A movable square block 24 is fixed to one side of the brake pad body 241 by welding. A sliding guide column 244 is slidably inserted into the inner wall of the movable square block 24. A mounting block 243 is mounted on one end of the sliding guide column 244. The mounting block 243 is fixed to the inner wall of the brake drum housing 8 by welding. When braking, the brake pad body 241 and the brake drum inside the brake drum housing 8 are in contact and rubbed to brake the vehicle shaft. This is a prior art and will not be described in detail.

[0033] Example 1: When the position of the brake pad body 241 is adjusted, the hollow movable block 24 is moved, thereby changing the depth of the sliding guide column 244 extending into the hollow movable block 24. The brake pad body 241 distributed throughout the entire circumference can more accurately display the current braking force changes within the circumference. The annular groove is used to ensure that the relevant measuring components do not occupy the space inside the brake drum housing.

[0034] A resistor 246 is fixed to the outer wall of the sliding guide column 244 by welding. A conductive block 242 is slidably sleeved on the outer wall of the sliding guide column 244. The inner wall of the conductive block 242 contacts the resistor 246 to form an electrical circuit. One end of the two conductive blocks 242 is connected to a wire, and a power supply 247 is electrically connected between the two wires. The power supply 247 is set in the electrical control box 4. An ammeter 248 is electrically connected between the power supply 247 and the resistor 246. One side of the conductive block 242 is fixed to the movable square block 24 by welding.

[0035] When the brake pad body 241 slides on the sliding guide post 244, the conductive block 242 has a very small resistance and can be approximately regarded as a wire, which can cause the resistance value of the resistor 246 to change, thereby intuitively reflecting the position of the brake pad body 241.

[0036] A spring 245 is connected between the mounting block 243 and the movable square block 24 , and the spring 245 is movably sleeved on the outside of the sliding guide column 244 ;

[0037] Example 2: When the brake pad body 241 is not subjected to a reaction force, the spring 245 is in a normal state. When the brake pad body 241 is subjected to an outward reaction force, the spring 245 is compressed. When the brake pad body 241 is subjected to an inward reaction force, the spring 245 is stretched. The position of the stretching or compression of the spring 245 is converted to the current braking force strength when a certain point of the rotor 7 is aligned with the brake pad body 241. The greater the degree of stretching, the greater the inward braking force strength, and the greater the degree of compression, the greater the outward braking force strength.

[0038] The installation structure uses the following braking force detection system:

[0039] It includes a braking force drawing module, a coordinate system establishment module, a braking force calculation module, an elastic force calculation module, and a displacement calculation module. The current measurement meter 248 is electrically connected to the displacement calculation module, the displacement calculation module is electrically connected to the elastic force calculation module, the elastic force calculation module is electrically connected to the braking force calculation module, the displacement calculation module is electrically connected to the coordinate system establishment module, and the braking force drawing module is electrically connected to the coordinate system establishment module and the braking force calculation module.

[0040] The braking force drawing module is used to draw a braking force cross-sectional diagram based on the braking force measured at each measurement point. The coordinate system establishment module is used to establish coordinate points based on the circumferential distribution position of each brake pad body 241. The braking force calculation module is used to estimate the braking force based on the radial position of the brake pad body 241 and the spring force. The elastic force calculation module is used to calculate the elastic force based on the compression amount of the spring 245. The displacement calculation module is used to calculate the displacement of the brake pad body 241 based on the reading of the current measurement meter 248.

[0041] The specific steps include:

[0042] S1. When real-time monitoring of the braking force is performed, the power supply of the motor is turned on to rotate the shaft of the vehicle;

[0043] S2. When braking, the brake pad body 241 is moved toward the brake drum by an external force, and the brake drum exerts a squeezing, attracting, or repelling effect on the brake pad body 241, repelling or attracting each brake pad body 241 outward or inward, resulting in a slight displacement.

[0044] S3, the resistance of the resistor 246 is detected by the system;

[0045] S4. Draw a braking force cross-sectional diagram based on the current magnitude of the current measuring meter 248 corresponding to the circumferentially distributed brake pad body 241 to obtain an intuitive dynamic braking force distribution diagram of the rotor 71;

[0046] S5. After the motor stops, a static braking force distribution diagram can be obtained according to the current value of the current measuring meter 248 corresponding to the brake pad body 241.

[0047] In the above step S3, specifically: when the power supply 247 is energized, the resistor sheet 246 and the conductive block 242 will form a power circuit. When the brake pad body 241 is displaced, the conductive block 242 will be driven to move, thereby changing the resistance of the power circuit connected to the resistor sheet 246, thereby affecting the current detected by the ammeter 248.

[0048] The present invention adopts the function of multiple split brake drum bodies, which can better fit the brake drum and effectively improve the braking efficiency. At the same time, the cross-sectional view of the braking force can be drawn to obtain a cross-sectional view of the braking force at a certain moment, which is convenient for better analyzing the contact uniformity between the brake drum and the brake pad.
