Description

Technical Field

[0001] The invention belongs to the technical field of automobile brake detection, and in particular relates to a flat brake testing device for motor vehicle detection. Background Art

[0002] Flatbed brake inspection usually refers to the process of performance testing of a vehicle's brake system on a flatbed test bench. The basic principle is to simulate the braking conditions of the vehicle during driving on a flatbed to detect whether the various performance indicators of the vehicle's brake system meet the standard requirements.

[0003] The disadvantage of the existing technology is that when a motor vehicle is driving for a long time, stones will be stuck in the gaps of the tire treads. The presence of stones will cause the friction between the tire and the ground to be significantly affected. When the tire is in a wet state, the friction will also be affected, which will lead to an increase in the braking distance and the subsequent braking detection process, resulting in inaccurate motor vehicle braking test results, which cannot truly reflect the braking ability of the motor vehicle.

At the same time, the moving front wheel pushes the first connecting seat 12 to move. The wiping pad 19 is used to wipe and clean the moisture on the surface of the rotating wheel to reduce the friction between the wheel and the inspection platform 2.

[0045] The rotating protection mechanism 5 includes a moving seat 51 and a rotating cylinder 52. Two electric hydraulic rods 55 are connected to the moving seat 51. The bottom ends of the electric hydraulic rods 55 are fixedly connected to the first placement slot 4. A rotating shaft 53 is passed through the side of the rotating cylinder 52.

[0047] The electric hydraulic rod 55 can control the moving seat 51 to move in the vertical direction, so that the contact groove 54 contacts the rotating cylinder 52. The electric hydraulic rod 55 controls the moving seat 51 to move downward, the contact groove 54 separates from the rotating cylinder 52, and the wheel contacts the rotating cylinder 52. The friction between the wheel and the rotating cylinder 52 controls the rotating cylinder 52 to rotate, limiting the forward movement of the vehicle and achieving a protective effect.

[0048] The movable wiping mechanism 8 includes an extrusion column 81 and a contact seat 82. The extrusion column 81 is connected in the second placement groove 6. The side portion of the contact seat 82 close to the extrusion column 81 is set as an inclined surface. The extrusion column 81 is in contact with the inclined surface portion of the contact seat 82. The extrusion column 81 is set to be cylindrical. The contact seat 82 is connected to the sliding support mechanism 9, and two first extension rods 83 are provided outside the contact seat 82.

[0049] The other end of the first extension rod 83 is connected to a sliding seat 84 , which is slidably connected in the sliding hole 7 . The sliding seat 84 is set to be rectangular. The sliding seat 84 is connected to a second extension rod 85 , and the other end of the second extension rod 85 is connected to the first connection seat 12 .

[0050] The side surface of the second extension rod 85 is connected with an intermediate rod 86 . The intermediate rod 86 is located in the sliding hole 7 . The other end of the intermediate rod 86 is connected to the sliding cleaning mechanism 13 .

[0051] The movement process of the first connecting seat 12 is controlled by the second extension rod 85, the sliding seat 84, and the first extension rod 83 to control the movement of the contact seat 82. When the first connecting seat 12 moves to the position of the first groove 11, the extrusion column 81 contacts the contact seat 82, and the inclined surface of the contact seat 82 is pushed downward by the extrusion column 81. The contact seat 82, the first extension rod 83, the second extension rod 85 and the first connecting seat 12 move downward into the first groove 11. The front wheel passes over the first groove 11 and the first connecting seat 12. After the first connecting seat 12 is separated from the front wheel, the first elastic component 93 controls the sliding block 92 to reset, and the sliding block 92, the horizontal plate 91, the vertical rod 94 and the contact seat 82 move away from the extrusion column 81. At the same time, the contact seat 82, the first extension rod 83, the sliding seat 84, and the second extension rod 85 control the first connecting seat 12 to move out of the first groove 11 and perform a reset action.

[0052] The sliding support mechanism 9 includes a horizontal plate 91, and two sliding blocks 92 are connected under the horizontal plate 91. The sliding blocks 92 are slidably connected in the sliding groove 10. The sliding block 92 is set to be T-shaped. The side of the sliding block 92 is connected to a first elastic component 93, and the other end of the first elastic component 93 is connected to the inner wall of the sliding groove 10.

[0053] Two vertical rods 94 are connected to the horizontal plate 91, and a connecting sleeve 95 is slidably connected to the outside of the vertical rod 94. An extension seat 96 is provided outside the connecting sleeve 95, and the extension seat 96 is connected to the contact seat 82. The top of the vertical rod 94 is connected to a limiting plate 97, and a second elastic component 98 is provided outside the vertical rod 94. The two ends of the second elastic component 98 are fixedly connected to the limiting plate 97 and the connecting sleeve 95 respectively.

[0054] The vertical rod 94 and the connecting sleeve 95 can cooperate to guide the vertical movement of the contact seat 82 and the first connecting seat 12, so that the first connecting seat 12 can move smoothly and stably in the vertical direction. After the contact seat 82 loses its extrusion, the second elastic component 98 can control the first connecting seat 12 to move upward, and the first connecting seat 12 moves out of the first groove 11. The first elastic component 93 can ensure that the first connecting seat 12 will not shake randomly. The sliding block 92 and the sliding groove 10 can cooperate to ensure that the contact seat 82 can stably move in the horizontal direction.

[0055] The sliding cleaning mechanism 13 includes two first movable connecting cylinders 131, the first movable connecting cylinder 131 is fixedly connected to the middle rod 86, a first sliding rod 132 is slidably connected inside the first movable connecting cylinder 131, the top of the first sliding rod 132 is connected to the second movable connecting cylinder 134, the side of the first sliding rod 132 is connected to the first guide column 133, and the first guide column 133 is slidably connected to the guide groove 14.

[0056] A second sliding rod 135 is slidably connected in the second movable connecting tube 134, a second guide column 138 is connected under the second sliding rod 135, the second guide column 138 is slidably connected in the guide hole 15, and a second connecting seat 136 is connected to the opposite ends of the two second sliding rods 135, and a cleaning brush 137 is provided on the arc surface of the second connecting seat 136.

[0057] The second extension rod 85 controls the first movable connecting tube 131 through the intermediate rod 86. During the movement of the first movable connecting tube 131, the first sliding rod 132 and the first guide column 133 are controlled to move. The first guide column 133 moves along the inclined section of the guide groove 14. The first guide column 133 is squeezed by the inclined section of the guide groove 14 and moves upward, so that when the wheel passes over the second connecting seat 136 and contacts the first connecting seat 12, the first connecting seat 12 is pushed to control the cleaning brush 137 to move up and automatically contact the outgoing wheel. The first sliding rod 132 drives the second movable connecting tube 134 and the second sliding rod 135 to move. The second sliding rod 135 drives the second connecting seat 136 and the cleaning brush 137 to move upward until they contact the front wheel. As the second connecting seat 136 moves, the movement of the second guide column 138 will be guided by the wave shape of the guide hole 15, so that the second sliding rod 135 continues to slide continuously in the second movable connecting tube 134. The cleaning brush 137 contacts the rotating wheel to clean the stones in the tire surface texture.

[0058] Working principle, when using:

[0059] When the motor vehicle is braked, the front wheel of the motor vehicle moves toward the first connecting seat 12 and contacts the rotating roller 18. The rotating roller 18 is controlled to rotate by the friction of the rotating front wheel. At the same time, the advancing front wheel pushes the first connecting seat 12 to move. At the same time, the wiping pad 19 wipes the rotating and advancing front wheel so that the front wheel can be wiped to remove moisture. The movement of the first connecting seat 12 is controlled by the second extension rod 85, the sliding seat 84, and the first extension rod 83. The second extension rod 85 controls the first movable connecting cylinder 131 through the intermediate rod 86. The movement of the first movable connecting cylinder 131 controls the movement of the first sliding rod 132 and the first guide column 133. The first guide column 133 moves along the inclined section of the guide groove 14. The first guide column 133 is squeezed by the inclined section of the guide groove 14 and moves upward.

[0060] The first sliding rod 132 drives the second movable connecting tube 134 and the second sliding rod 135 to move, and the second sliding rod 135 drives the second connecting seat 136 and the cleaning brush 137 to move upward until they are in contact with the front wheel. As the second connecting seat 136 moves, the second guide column 138 is guided by the wave shape of the guide hole 15 during its movement, so that the second sliding rod 135 continuously slides in the second movable connecting tube 134, and the cleaning brush 137 continuously slides in the horizontal direction in the front and rear directions. The cleaning brush 137 that swings back and forth contacts the rotating front wheel to clean the stones or debris stuck in the front wheel texture.

[0061] When the first connecting seat 12 moves to the position of the first groove 11, the extrusion column 81 contacts the contact seat 82, and the inclined surface of the contact seat 82 is pushed downward by the extrusion column 81. The contact seat 82, the first extension rod 83, the second extension rod 85 and the first connecting seat 12 move downward into the first groove 11. The front wheel passes over the first groove 11 and the first connecting seat 12. After the first connecting seat 12 is separated from the front wheel, the first elastic component 93 controls the sliding block 92 to reset, and the sliding block 92, the cross plate 91, the vertical rod 94 and the contact seat 82 move away from the extrusion column 81. At the same time, the second elastic component 98 controls the connecting sleeve 95 and The extension seat 96 moves upward, and at the same time, the contact seat 82, the first extension rod 83, the sliding seat 84, and the second extension rod 85 control the first connection seat 12 to move out of the first groove 11 and perform a reset action. The intermediate rod 86 controls the first movable connection cylinder 131 to move. At the same time, when the first guide column 133 moves along the inclined section of the guide groove 14, the inclined section squeezes the first guide column 133 and the first movable connection cylinder 131 to move downward, so that the second connection seat 136 moves into the second groove 16, and the rear wheel moves to the contact position with the first connection seat 12. The above actions are repeated to achieve the cleaning of the rear wheel.

[0062] After all four wheels of the vehicle are moved to the inspection platform 2, the vehicle brakes. The inspection platform 2 detects the force data of the braking process through sensors, analyzes it through the computer system, and determines the braking performance of the vehicle. After the vehicle brakes and detects it, it starts moving forward again. If there is an unexpected operation and the vehicle loses control, the speed sensor 3 detects the speed of the vehicle and compares the speed with the safe speed range. If the vehicle speed exceeds the safe range, the control system controls the electric hydraulic rod 55 to shorten the action, and the electric hydraulic rod 55 controls the moving seat 51 to move downward, the contact groove 54 separates from the rotating cylinder 52, and the wheel contacts the rotating cylinder 52. The friction between the wheel and the rotating cylinder 52 controls the rotation of the rotating cylinder 52, limits the forward movement of the vehicle, and protects against unexpected loss of control.

[0063] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
