Description

Technical Field

[0001] The utility model relates to the technical field of automobile braking, in particular to a vehicle braking device. Background Art

[0002] Over long-term use, brake pads gradually become thinner, and their braking performance decreases accordingly. If excessive brake pad wear is not detected and replaced promptly, the braking distance will increase significantly, seriously affecting the safe driving of the vehicle and even causing traffic accidents. However, the current structural design of vehicle braking systems makes it extremely difficult to monitor brake pad wear. Because the brake pads are installed inside the brake caliper and are tightly constrained by components such as the wheel hub, it is difficult to directly observe and accurately measure the wear status of the brake pads. This inconvenience in directly monitoring brake pad wear makes it difficult for vehicle owners and maintenance personnel to obtain key information such as the remaining thickness of the brake pads in a timely and accurate manner, making it impossible to schedule brake pad replacement maintenance at the appropriate time, thereby creating serious hidden dangers to vehicle braking safety.

[0003] To this end, the utility model provides a vehicle braking device. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4 A vehicle braking device includes a brake disc 1, a brake caliper 11 and a brake pad 12. The brake caliper 11 is sleeved on the outside of the brake disc 1. Both ends of the brake pad 12 are supported by supporting diagonal rods 2. The two supporting diagonal rods 2 are connected by a docking plate 22. The outer wall of the supporting diagonal rod 2 is fixedly connected to a positioning plate 3. An inner mounting plate 31 and an outer mounting plate 32 corresponding to the positioning plate 3 are installed on the brake caliper 11. A limiting rod 33 that is slidably connected to the outer mounting plate 32 is fixedly connected to one side of the positioning plate 3.

[0020] Among them, the outer wall of the docking plate 22 is fixedly connected to the fixing plate 23, the fixing plate 23 is slidingly connected to the inner wall of the brake caliper 11, a connecting rod 24 is fixedly connected to the fixing plate 23, and the outer side of the docking plate 22 is rotatably connected to the extension rod 25, and one end of the connecting rod 24 is threadedly connected to the extension rod 25.

[0021] It should be noted that one end of the fixing plate 23 described in this embodiment corresponds to the inner wall of the brake pad 12 , one side of the fixing plate 23 is offset from the supporting diagonal rod 2 , and the connecting rod 24 and the extension rod 25 are offset from the supporting diagonal rod 2 .

[0022] A side plate 251 corresponding to the extension rod 25 is fixedly connected to the outer wall of the docking plate 22 , and the extension rod 25 is rotatably connected to the side plate 251 .

[0023] It should be noted that the rotational connection between the extension rod 25 and the side plate 251 described in this embodiment can be achieved by using an annular mortise and tenon connection between the extension rod 25 and the outer wall and inner wall of the side plate 251.

[0024] Further Figure 1-4As shown, the brake disc 1 is used to be installed on the outer wall of the brake disc 1 through the brake pad 12 when in use. At this time, the brake pad 12 installed through the inner wall of the brake disc 1 corresponds to the two side surfaces of the brake disc 1, and the piston is driven to move by hydraulic means, so that the piston can push the brake pad 12, so that one end of the brake pad 12 can be supported on the surface of the brake disc 1, so that the brake pad 12 can play a braking role on the brake disc 1. During use, the brake pad 12 will continue to wear out due to factors such as friction over time. After the brake pad 12 is seriously worn out, it will seriously affect the braking effect of the car, which is not conducive to the safe driving of the car. Since the brake pad 12 is generally installed in the brake caliper 11, and the brake pad 12 is in the tire and is limited by the wheel hub, etc. The cam 24 is held in place by the support rod 23 and the support rod 25 is held in place by the support rod 26. The cam 24 is held in place by the support rod 27 and the support rod 28 is held in place by the support rod 29. The cam 24 is held in place by the support rod 26 and the support rod 28 is held in place by the support rod 29. When the brake pad 12 is pressed, the supporting oblique rod 2 and the docking plate 22 can be pushed synchronously with it, and the supporting oblique rod 2 can be installed at the innermost end position of the brake pad 12, so that the supporting oblique rod 2 and the docking plate 22 can have a sufficient distance from the brake disc 1 to avoid wear on the brake disc 1. At the same time, when the brake pad 12 is constantly worn under use, the distance between the brake pad 12 and the brake disc 1 is continuously increased by the hydraulic pressure. At this time, the position of the supporting oblique rod 2 fixed on the outer wall of the brake pad 12 is inconvenient, so that the distance between the supporting oblique rod 2 and the docking plate 22 and the brake disc 1 is continuously close, so that the device can control the hydraulic assembly of the vehicle to support the brake pad 12 when it is necessary to check the wear of the brake pad 12. The brake disc 1 is supported on both sides, and the wear degree of the brake pad 12 is judged by observing the distance between the supporting diagonal rod 2 and one side of the docking plate 22 and the one side of the brake disc 1. At the same time, the change in the distance between the supporting diagonal rod 2 and the docking plate 22 can be fixed on the supporting diagonal rod 2 through the positioning plate 3. One end of the positioning plate 3 extends to the outside of the brake caliper 11, making it easier to observe. At the same time, according to the sliding of the limiting rod 33 between the inner mounting plate 31 and the outer mounting plate 32, it can be judged according to the distance between the limiting rod 33 and the outer mounting plate 32 outside the brake caliper 11, so that it is outside the brake caliper 11 and in a position that is easy to observe, so that the device can facilitate the user to directly check the wear condition of the brake pad 12, avoiding the inconvenience of knowing the wear condition.If the car is still in use despite being severely worn, it will pose a greater risk to the safe driving of the car.

[0025] In one embodiment of the present invention, Figures 1-4 As shown, one end of the supporting diagonal rod 2 is fixedly connected to an arc-shaped clamping rod 21 that matches the two ends of the brake pad 12, and the arc-shaped clamping rod 21 is clamped with the two ends of the brake pad 12.

[0026] It should be noted that the inner wall of the arc-shaped clamping rod 21 described in this embodiment matches the outer wall of the brake pad 12 , and the supporting diagonal rod 2 and the arc-shaped clamping rod 21 are located at the rear section of the brake pad 12 .

[0027] Specifically, the arc-shaped clamping rod 21 fixedly connected to one end of the supporting diagonal rod 2 is used to engage with the two ends of the brake pad 12 through the inner wall of the arc-shaped clamping rod 21 when in use, so that the supporting diagonal rod 2 can be firmly supported on the two ends of the brake pad 12, and the position of the supporting diagonal rod 2 is limited, so that the supporting diagonal rod 2 can be displaced synchronously with the brake pad 12.

[0028] In one embodiment of the present invention, Figures 1-4 As shown, a clamping plate 34 is fixedly connected to the brake caliper 11 , and the clamping plate 34 is connected to the inner mounting plate 31 and the outer mounting plate 32 via a latch 341 .

[0029] It should be noted that the two ends of the clamping plate 34 described in this embodiment are in contact with the inner mounting plate 31 and the outer mounting plate 32 , and the latch 341 passes through the inner mounting plate 31 , the outer mounting plate 32 and the clamping plate 34 .

[0030] Specifically, the clamping plate 34 fixedly connected to the brake caliper 11 is used to install the inner mounting plate 31 and the outer mounting plate 32. The inner mounting plate 31, the outer mounting plate 32 and the clamping plate 34 are connected by the pin 341, so that the inner mounting plate 31 and the outer mounting plate 32 can be installed and fixed on one end of the brake caliper 11, so that the positioning plate 3 can be limited by the limiting rod 33 to ensure horizontal displacement with the brake pad 12, thereby ensuring accurate judgment of the degree of wear of the brake pad 12.

[0031] In one embodiment of the present invention, Figures 1-4 As shown, a connection hole 231 is formed at the connection between the fixing plate 23 and the brake caliper 11 , and the connection holes 231 are connected via a sliding rod 232 .

[0032] It should be noted that the sliding rod 232 and the connecting hole 231 described in this embodiment are engaged and connected.

[0033] Specifically, the connecting hole 231 enables the fixing plate 23 to be installed and supported on the inner wall of the brake caliper 11, and is slidably connected to the slide rod 232 through the connecting hole 231, so that the fixing plate 23 can slide on the slide rod 232, thereby being slidably connected to the inner wall of the brake caliper 11, so that when the docking plate 22 is synchronously displaced by the displacement of the brake pad 12, the fixing plate 23 is prevented from limiting its displacement, and the position of the docking plate 22 can be set.

[0034] In one embodiment of the present invention, Figures 1-4 As shown, a cross bar 331 is fixedly connected to one side of the inner mounting plate 31 , and the cross bar 331 is slidably connected to one end of the limiting rod 33 .

[0035] It should be noted that the limiting rod 33 described in this embodiment passes through the outer mounting plate 32 , and one end of the limiting rod 33 is provided with a sliding groove matching the cross bar 331 .

[0036] Specifically, the limit rod 33 passes through the outer mounting plate 32 so that the limit rod 33 is slidably connected to the outer mounting plate 32, and the pin 341 fixedly connected to one side of the inner mounting plate 31 is slidably connected to the limit rod 33, ensuring that the limit rod 33 slides vertically relative to the inner mounting plate 31 and the outer mounting plate 32, thereby ensuring that when the positioning plate 3 and the brake pad 12 are displaced synchronously, one end of the positioning plate 3 is horizontally displaced.

[0037] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0038] Working principle: When in use, one side of the two supporting diagonal rods 2 is supported on one end of the brake pad 12, and the extension rod 25 connected to the side plate 251 is rotated to shrink the distance between the extension rod 25 and the connecting rod 24, so that it can pull the outer wall of one end of the docking plate 22. The position of the brake pad 12 is fixed by pressing the supporting diagonal rods 2 against both ends of the brake pad 12. When it is necessary to check the wear of the brake pad 12, the brake pad 12 can be supported on both sides of the brake disc 1 by controlling the hydraulic components of the vehicle. By observing the support diagonal rods 2 and one side of the docking plate 22 and the brake disc 1, the brake pad 12 can be supported on both sides of the brake disc 1. The distance between the sides can be used to judge the degree of wear of the brake pad 12. At the same time, it can be fixed on the supporting diagonal rod 2 through the positioning plate 3. One end of the positioning plate 3 extends to the outside of the brake caliper 11. At this time, it can be judged according to the distance between the limit rod 33 outside the brake caliper 11 and the outer mounting plate 32, so that it is outside the brake caliper 11 and in a position that is easy to observe. The device can facilitate users to directly check the wear of the brake pad 12, avoiding the inconvenience of knowing the wear condition. When it is still used when the wear is large, it brings greater risks to the safe driving of the car.
