Description

Technical Field

[0001] The present invention relates to the technical field related to brake detection, and in particular to a synchronous detection device and method for a brake chassis and a brake system. Background Art

[0002] The brake system is a vital component of a vehicle. Its primary function is to slow or stop the vehicle to ensure safe driving. As a critical component of vehicle safety, the brake system's health is directly related to driving safety. Therefore, brake system testing is of paramount importance.

[0003] In the existing brake testing process, such as the Chinese patent publication number CN116296453A, a vehicle brake testing device is disclosed, which includes a testing assembly, a wheel edge support portion and a follower; the testing assembly includes a fixed bracket, at least two rollers and a drive motor, and the at least two rollers are parallel to the ground and coaxially arranged, and one end of each roller is rotatably connected to the fixed bracket, and the other end is connected to the output shaft side of the drive motor; the wheel edge support portion is arranged on both sides of the roller, and is used to support the wheels of the vehicle under inspection and make them contact with the roller; the follower is arranged between the wheel edge support portion and the roller, and is used to keep the wheel in a driven state when the roller rotates to drive the wheel.

[0004] In the above-mentioned prior art, the actual braking performance of the vehicle under test is mainly detected by setting up a pair of coaxial rollers in the left and right groups of rollers. However, the above-mentioned prior art does not take into account that the braking performance of the vehicle is multifaceted, and only considers the braking force while ignoring its synchronization. When braking, when the braking force of the tire on one side is greater than that of the other side, the vehicle will shift to the side with smaller braking force when braking. This shift may cause the driver to lose control of the vehicle, especially when driving at high speeds or emergency braking, increasing the risk of accidents. In addition, due to uneven braking force, the effective braking force is reduced, which will cause the vehicle to take a longer distance to stop. The increased braking distance may cause a collision in an emergency, and the tire with a larger braking force may be replaced prematurely due to excessive wear. Uneven wear may also cause other problems with the tire, such as uneven tire surface may cause vehicle instability when driving.

[0005] Based on this, the above-mentioned prior art still has room for improvement. Summary of the Invention

DETAILED DESCRIPTION

[0038] The following is combined with Figures 1-8 This application is described in further detail.

[0039] The embodiments of the present application disclose a brake chassis and brake system synchronization detection device and detection method, which realizes the detection of the braking synchronization between the left and right tires of a vehicle by transmitting and converting the movement of the tires.

[0040] Reference Figure 1 、 Figure 2As shown, a brake chassis and brake system synchronization detection device includes a bearing platform 1, a hydraulic lifting platform 2, a supporting base 3, a docking module 4, a transition module 5, a detection module 6, and a display module 7. The hydraulic lifting platform 2 is arranged in the middle of the bearing platform 1, and the hydraulic lifting platform 2 lifts the vehicle. The supporting base 3 is installed at the bottom of the bearing platform 1. The docking module 4 is symmetrically arranged on the supporting base 3. The docking module 4 contacts and cooperates with the tire of the vehicle. The transition module 5 is symmetrically arranged at the edge of the bearing platform 1. The transition module 5 cooperates the docking module 4 with the detection module 6. The detection module 6 is arranged inside the bearing platform 1. The detection module 6 detects the synchronization of the left and right tires of the vehicle during braking. The display module 7 is arranged on the surface of the bearing platform 1. The display module 7 intuitively displays the detection results for observation by personnel.

[0041] During actual work, the vehicle is driven onto the carrying platform 1, and the hydraulic lifting platform 2 lifts the vehicle. After that, the personnel can easily observe whether the brake oil pipes, hoses and connectors are leaking or damaged, as well as the wear of the tires, whether the wheel hubs are deformed, etc. After the observation is completed, the docking module 4 adjusts its position so as to contact and cooperate with the tires of the vehicle. At the same time, the docking module 4 is connected and cooperated with the transition module 5. After that, the vehicle is started, and the docking module 4 converts and transmits the movement of the tires. After stepping on the brakes, the detection module 6 detects the synchronization of the tires when the vehicle brakes. After that, it is confirmed by observing the display module 7 whether there is a braking time difference between the left and right tires of the vehicle, thereby confirming whether the braking system is normal. This application ensures the balance of the braking force of the braking system by detecting the braking time error between the left and right tires of the vehicle, thereby maintaining the life safety of the driver.

[0042] Reference Figure 1 As shown, the front and rear ends of the carrying platform 1 are slope structures, which are convenient for vehicles to travel, and the top of the carrying platform 1 is a flat surface.

[0043] During actual operation, the vehicle drives up the slope from one end of the carrying platform 1 to the top plane, and after the inspection is completed, drives down the slope from the other end.

[0044] Reference Figure 3-Figure 5As shown, in order to feel the movement of the tire, the present application is provided with a docking module 4, which includes a mobile support bracket 41, a mounting plate 42, a V-shaped frame 43, a roller 44, a linkage shaft 45, a docking flange 46, a clamping member 47, and a belt 48. The mobile support bracket 41 is set on the supporting base 3 by sliding left and right through the X-axis electric slider, and the mounting plate 42 is set on the mobile support bracket 41 by sliding up and down through the Z-axis electric slider. The V-shaped frame 43 is installed at the upper end of the mounting plate 42. When the V-shaped frame 43 is clamped with the tire, it can adapt to wheels of different sizes. Tire, to increase the applicability of this application, a roller 44 is evenly rotated on the V-frame 43 through a pin shaft. When the roller 44 is in contact with the tire, under the action of friction, the roller 44 is driven by the tire to rotate synchronously. When the tire stops, the roller 44 stops rotating, thereby facilitating the detection of the movement state of the tire. A linkage shaft 45 is rotatably set at the lower end of the mounting plate 42, and a circular docking flange 46 and a rectangular clip 47 are sequentially installed in the peripheral extension direction of the linkage shaft 45. The linkage shaft 45 and the roller 44 are matched through a belt 48.

[0045] During the actual docking process, the mobile support frame 41 moves toward the middle under the drive of the X-axis electric slider, the V-shaped frame 43 comes under the tire, and the linkage shaft 45 is gradually inserted into the transition module 5 and clamped. Afterwards, the Z-axis electric slider drives the mounting plate 42 to move upward, and the V-shaped frame 43 moves upward to clamp with the tire, and the roller 44 contacts the tire. When the tire rotates, the roller 44 rotates under the action of friction, and under the action of the belt 48, the linkage shaft 45 rotates, thereby transmitting the movement of the tire to the transition module 5.

[0046] Reference Figure 3 、 Figure 5 As shown, the transition module 5 includes a sliding frame 51, a transition piece 52, an avoidance hole 53, a snap ring 54, a snap groove 55, and a cam piece 56. The sliding frame 51 is nested and installed in the side wall of the carrying platform 1. A transition piece 52 is provided on the sliding frame 51 for sliding up and down. A spring 1 is connected between the transition piece 52 and the sliding frame 51, and the spring acts to reset. An avoidance hole 53 is provided in the middle of the transition piece 52. The diameter of the avoidance hole 53 is the same as the outer diameter of the docking flange 46. The diameter of the avoidance hole 53 is larger than the maximum distance of the snap member 47 (that is, the snap member 47 can smoothly pass through the avoidance hole 53 without interference). The snap ring 54 is rotatably set on the side of the transition piece 52. A snap groove 55 that is snap-fitted with the snap member 47 is provided in the middle of the snap ring 54, and a cam piece 56 is installed on the outer periphery of the end of the snap ring 54.

[0047] During actual operation, the linkage shaft 45 passes through the avoidance hole 53 and is inserted into the clamping groove 55. At this time, the docking flange 46 enters the avoidance hole 53, and the clamping part 47 is clamped with the clamping groove 55. Afterwards, when the linkage shaft 45 rotates, driven by the clamping part 47, the clamping ring 54 rotates, and the cam part 56 rotates with the clamping ring 54, while the transition part 52 remains stationary (the docking flange 46 rotates in the avoidance hole 53, and the docking flange 46 plays a supporting role to prevent the linkage shaft 45 from hanging too much in the avoidance hole 53, resulting in unstable rotation).

[0048] Reference Figure 6 As shown, in order to perform synchronous detection of tires, the present application is provided with a detection module 6, which includes a balancing pushing component 61, a working component 62, and a hydraulic component 63. The balancing pushing component 61 is arranged inside the carrying platform 1, and the working component 62 is arranged inside the carrying platform 1. The working component 62 and the balancing pushing component 61 are arranged sequentially, and the hydraulic component 63 is installed in the carrying platform 1. The hydraulic component 63 transmits the changes of the working component 62 to the display module 7.

[0049] Reference Figure 6 、 Figure 7 As shown, the balancing pushing assembly 61 includes a structural member 611, a sliding member 612, a balancing plate 613, and a pressing member 614. The structural member 611 is installed inside the carrying platform 1. The sliding member 612 is set in the middle of the structural member 611 for sliding back and forth. A spring 2 is connected between the sliding member 612 and the structural member 611. The spring 2 plays a reset role. The end of the sliding member 612 is rotated by a pin to set a balancing plate 613. A spring 3 is connected between the balancing plate 613 and the sliding member 612. The spring 3 is a torque spring. The spring 3 plays a role in maintaining the state of the balancing plate 613 and resetting. The balancing plate 613 and the cam member 56 are extruded together. The pressing member 614 is symmetrically installed on the balancing plate 613. The structural member 611 is provided with an avoidance groove corresponding to the position of the pressing member 614. The avoidance groove only serves as a structural groove to avoid interference.

[0050] Reference Figure 6 、 Figure 7As shown, the working assembly 62 includes a second structural member 621, a load-bearing bracket 622, a blocking plate 623, a movable shell 624, an L-shaped member 625, and a reset assembly. The second structural member 621 is installed inside the load-bearing platform 1, and the load-bearing bracket 622 is arranged to slide back and forth on the second structural member 621. The load-bearing bracket 622 is arranged symmetrically on the left and right. A spring four is connected between the load-bearing bracket 622 and the second structural member 621, and the spring four plays a reset role. The blocking plate 623 is arranged to slide left and right on the second structural member 621, and a spring five is connected between the blocking plate 623 and the load-bearing bracket 622, and the spring five plays a reset role. The blocking plate 623 and the pressing member 614 are in contact and extrusion fit, and the symmetrically arranged blocking plates 623 are in mutual contact and extrusion fit. The movable shell 624 is arranged to slide back and forth in the load-bearing platform 1, and the movable shell 624 is arranged symmetrically on the left and right. A spring six is ​​connected between the movable shell 624 and the load-bearing platform 1, and the spring six plays a reset role. The part 625 is arranged to slide left and right in the movable shell 624. A spring seven is connected between the L-shaped part 625 and the movable shell 624. The spring seven always pushes the L-shaped part 625 toward the middle, and the L-shaped part 625 and the blocking plate 623 are in a squeeze fit. In the initial state, due to the action of the spring seven, the L-shaped part 625 always squeezes the blocking plate 623, so that the two blocking plates 623 arranged symmetrically on the left and right are in a mutually squeezed state. In this state, if the blocking plates 623 are pushed synchronously in the front and rear directions, the blocking plates 623 are always in a balanced state of mutual squeezing. If the blocking plates 623 are not pushed synchronously and cause the front and rear directions to be misaligned, then under the action of the spring seven, the blocking plates 623 will also be misaligned in the left and right directions, so that the L-shaped part 625 can move in the left and right directions, thereby triggering the subsequent hydraulic component 63 to record the asynchronous situation. The reset component is arranged in the movable shell 624 to reset the L-shaped part 625.

[0051] During the actual test, the rotating cam member 56 squeezes the balance plate 613 (the balance plate 613 is relatively wide, and even if the cam member 56 has been adjusted up and down in the early stage, the two can still cooperate), and the sliding member 612 is squeezed and moved synchronously. Under the action of the second spring, the sliding member 612 moves back and forth, and the balance plate 613 moves back and forth synchronously. If the left and right movement states of the tire are synchronized, the squeezing caused by the cam member 56 (symmetrical arrangement) on the balance plate 613 is synchronized, and the balance plate 613 maintains a balanced state and is pushed back and forth, so that the pressing member 614 synchronously pushes the blocking plate 623 to move. The blocking plate 623 is pushed back and forth but cannot contact the hydraulic assembly 63, so there is no abnormality. When the left and right movement states of the tire are not synchronized (they do not stop at the same time when braking), the cam member 56 stops at one place and the other stops at the other. The first part continues to rotate, and the squeezing of the balancing plate 613 by the cam member 56 changes, and the balancing plate 613 rotates unbalancedly, so that the pushing of the blocking plate 623 by the pressing member 614 is asynchronous, and the blocking plate 623 is displaced in the front-to-back direction. Under the action of the spring seven, the blocking plate 623 is also dislocated in the left-to-right direction, so that the L-shaped member 625 moves out in the left-to-right direction. At this time, the moved blocking plate 623 is no longer in contact with the pressing member 614, and the L-shaped member 625 moves to a position where it can contact the pressing member 614. Afterwards, the pressing member 614 repeatedly squeezes the L-shaped member 625, and the L-shaped member 625 is squeezed, thereby driving the movable shell 624 to move back and forth. The moving L-shaped member 625 repeatedly squeezes the hydraulic assembly 63 to record and feedback the asynchronous situation of the tire.

[0052] Reference Figure 8 As shown, in order to reset the L-shaped member 625, the present application is provided with a reset component, which includes a positioning card plate 626 and a reset drive 627. The positioning card plate 626 is installed on the L-shaped member 625, and the reset drive 627 is set in the movable shell 624. When working, the reset drive 627 pushes the positioning card plate 626 to move and reset it.

[0053] Reference Figure 7 As shown, in order to intuitively display the braking time difference between tires, the present application is provided with a hydraulic component 63, which includes a hydraulic cylinder 631 and a piston 632. The hydraulic cylinder 631 is installed inside the supporting platform 1, and a piston 632 is slidingly provided inside the hydraulic cylinder 631. A spring eight is connected between the piston 632 and the hydraulic cylinder 631, and the spring eight plays a reset role. The piston 632 and the L-shaped part 625 are in contact and extrusion fit, and the hydraulic cylinder 631 is connected to the display module 7 through a pipeline.

[0054] Reference Figure 1 As shown, the display module 7 is a pressure meter in the prior art.

[0055] During actual operation, the piston 632 is repeatedly squeezed by the L-shaped part 625, thereby increasing the pressure of the hydraulic cylinder 631. The pressure instrument intuitively displays this pressure change. By observing the pressure difference between the pressure instruments (the pressure instruments correspond to the hydraulic cylinder 631 one by one), the braking time difference between the tires can be clearly judged. If there is no pressure difference, it indicates that the tires stop synchronously and the braking performance is excellent. If the pressure difference is small (within the standard range), it indicates that the tires stop nearly synchronously and the braking performance is acceptable. If the pressure difference is large (outside the standard range), it indicates that there is a large time difference between the tires stopping. The larger the pressure difference, the greater the time difference, and the higher the degree of brake damage.

[0056] Last reference Figure 1-Figure 2 As shown, the present application also discloses a detection method for a brake chassis and a brake system synchronous detection device, and the specific detection method includes the following steps:

[0057] Step 1: Drive the vehicle onto the carrying platform 1;

[0058] Step 2: The hydraulic lifting platform 2 lifts the vehicle;

[0059] Step 3: Check the brake hoses, hoses and connectors for leaks or damage, as well as the wear of the tires and whether the wheels are deformed.

[0060] Step 4: The docking module 4 adjusts its position so as to come into contact with the tire of the vehicle;

[0061] Step 5: Start the vehicle and perform an actual brake test;

[0062] Step 6: The detection module 6 detects the synchronization of the tires when the vehicle brakes;

[0063] Step 7: Observe the display module 7 to confirm whether the vehicle's brake system is normal;

[0064] Step 8: The test is completed and a test report is given.
