Description

Technical Field

[0001] This utility model relates to the field of motor vehicle inspection technology, and in particular to a roller brake device for motor vehicle inspection. Background Technology

[0002] Vehicle inspection is an examination to determine the technical condition or working capability of a vehicle. During the use of a vehicle, as the usage time increases, its parts gradually wear, corrode, deform, and age, resulting in a decline in the vehicle's technical performance. Brake performance testing is an important indicator in motor vehicle inspection and an important item to ensure the safe driving of vehicles.

[0003] In existing vehicle inspection benches, a roller brake device is commonly used, consisting of a brake band and a cylinder located below the rollers. When braking, the cylinder pushes the brake band upwards, using the friction between the brake band and the rollers to brake the rollers. However, this braking method produces relatively weak braking force, and in particular, it cannot reliably lock the rollers. Therefore, slippage often occurs when the vehicle starts, thus affecting the vehicle's ability to leave the inspection bench normally. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the prior art of facilitating the removal of vehicles from the inspection platform, and to propose a roller brake device for motor vehicle inspection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A roller brake device for motor vehicle inspection includes two sets of first rollers and second rollers rotating inside a housing. The two first rollers are rotatably connected by a coupling, and the two second rollers are rotatably connected by another coupling. Both sets of first rollers and second rollers are braked by a brake assembly.

[0007] The braking assembly includes a first brake wheel fixed to one end of one of the first and second rollers, and two first brake pads that cooperate with the first brake wheel to brake the first and second rollers.

[0008] In some embodiments, both first brake pads slide laterally on the surface of the guide plate, the two first brake pads move synchronously through two connecting arms and an electric push rod, both first brake pads are located between two first brake wheels, and the first brake pads are arc-shaped to match the diameter of the first brake wheels.

[0009] In some embodiments, the guide plate is fixed to the surface of one of the partitions, and the surface of the guide plate is provided with a first guide groove and a second guide groove. The first guide groove is arranged horizontally, and the second guide groove is arranged vertically. Both first brake pads slide on the inner wall of the first guide groove by a slider.

[0010] In some embodiments, the upper ends of the two connecting arms are respectively hinged to the surfaces of the two first brake pads, and the lower ends of the two connecting arms are hinged to the surface of the connecting block. The connecting block slides on the inner wall of the second guide groove and is driven to rise and fall by an electric push rod.

[0011] In some embodiments, two sets of detection rollers are symmetrically arranged inside the housing, and each detection roller has an adjustment component at both ends for adjusting the position of the detection roller.

[0012] In some embodiments, the adjustment assembly includes a swing arm that rotates at one end of the detection drum and a hydraulic rod for driving the swing arm to rotate. The swing arm is L-shaped, with its middle portion rotating on the inner wall of the housing via a connecting shaft, and its lower end driven by the hydraulic rod.

[0013] In some embodiments, a second brake wheel is fixed to one end of each of the two detection rollers that are far apart from each other, and a second brake pad that cooperates with the second brake wheel is fixed to the top of the housing. The second brake pad is an arc shape that cooperates with the diameter of the second brake wheel.

[0014] In some embodiments, the first roller and the second roller are connected by a transmission assembly.

[0015] In some embodiments, the housing is divided into cavities by two partitions, both of which are fixed to the inner wall of the housing, and both couplings and transmission components are located inside the cavities.

[0016] Compared with the prior art, the present invention provides a roller brake device for motor vehicle inspection, which has the following beneficial effects.

[0017] 1. This utility model, by setting a brake assembly, causes the electric push rod to push the connecting block to slide upward. The angle of the two connecting arms is automatically adjusted so that the first brake pad abuts against the surface of the first brake wheel, thus synchronously braking the first roller and the second roller. The two sets of first rollers and second rollers are connected by a coupling, so that the other set of first rollers and second rollers can be synchronously braked.

[0018] 2. This utility model, by setting an adjustment component, enables the hydraulic rod to drive the swing arm to rotate through the connecting shaft, thereby allowing the swing arm to adjust the position of the detection roller, which can adapt to tires of different diameters. This allows the detection roller to come into contact with tires of different diameters. Under the action of the second brake wheel and the second brake pad, the detection roller drives the second brake wheel to come into contact with the surface of the second brake pad, thereby braking the rotation of the detection roller.

[0019] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-6 A roller brake device for motor vehicle inspection includes two sets of first rollers 102 and second rollers 103 rotating inside a housing 1. The housing 1 is divided into cavities by two partitions 101, both of which are fixed to the inner wall of the housing 1. A gap is provided between the first rollers 102 and the second rollers 103. The two first rollers 102 are rotatably connected by couplings 2, and the two second rollers 103 are rotatably connected by another coupling 2. Both couplings 2 are located inside the cavities. The transmission assembly 3 is connected by transmission components. The transmission assembly 3 includes two synchronous pulleys 301 that are respectively fixed to one end of the first roller 102 and the second roller 103. The two synchronous pulleys 301 are connected by a synchronous belt 302. The transmission assembly 3 is located inside the cavity. The two second rollers 103 are connected by a drive motor. One end of the output shaft of the drive motor and one end of the second roller 103 are respectively fixed with a transmission wheel. The two transmission wheels are connected by a transmission belt. Both sets of first rollers 102 and second rollers 103 are braked by a brake assembly 4.

[0030] It is understandable that by connecting the two first rollers 102 and the two second rollers 103 through the coupling 2, and with the cooperation of the transmission assembly 3, the first rollers 102 and the second rollers 103 can rotate synchronously, thus avoiding the speed difference between the two sets of first rollers 102 and second rollers 103 caused by transmission deviation, which would affect the results of the vehicle braking test process.

[0031] Specifically, the brake assembly 4 is located inside the cavity and is disposed on the surface of one of the partitions 101. The brake assembly 4 includes a first brake wheel 401 fixed to one end of one of the first rollers 102 and the second roller 103, and two first brake pads 402 that cooperate with the first brake wheel 401 to brake the first roller 102 and the second roller 103. The two first brake pads 402 slide laterally on the surface of the guide plate 403. The two first brake pads 402 move synchronously through two connecting arms 405 and an electric push rod 406. The two first brake pads 402 are located between the two first brake wheels 401, and the first brake pads 402 are arc-shaped to match the diameter of the first brake wheel 401.

[0032] The guide plate 403 is fixed on the surface of one of the partitions 101. The surface of the guide plate 403 is provided with a first guide groove 4031 and a second guide groove 4032. The first guide groove 4031 is arranged horizontally and the second guide groove 4032 is arranged vertically. Both first brake pads 402 slide on the inner wall of the first guide groove 4031 by a slider.

[0033] The upper ends of the two connecting arms 405 are respectively hinged to the surfaces of the two first brake pads 402, and the lower ends of the two connecting arms 405 are hinged to the surface of the connecting block 404. The connecting block 404 slides on the inner wall of the second guide groove 4032. The electric push rod 406 is fixed on the lower surface of the connecting block 404, and the lower end of the electric push rod 406 is fixed on the inner wall of the housing 1.

[0034] Understandably, when braking is required on the first roller 102 and the second roller 103, the connecting block 404 is pushed upward by the electric push rod 406, causing the two connecting arms 405 to automatically adjust their angles. This causes the two connecting arms 405 to push the two first brake pads 402 away from each other, so that the first brake pads 402 abut against the surface of the first brake wheel 401, thereby synchronously braking the first roller 102 and the second roller 103. Since the two sets of first rollers 102 and second rollers 103 are connected by the coupling 2, the other set of first rollers 102 and second rollers 103 can be synchronously braked.

[0035] Specifically, two sets of detection rollers 5 are symmetrically arranged inside the housing 1. The detection rollers 5 are used to detect the vehicle's braking data. The two sets of detection rollers 5 are located between the two sets of first rollers 102 and second rollers 103, respectively. The detection rollers 5 are existing technology and will not be described in detail. Adjustment components 6 for adjusting the position of the detection rollers 5 are respectively provided at both ends of the detection rollers 5.

[0036] The adjustment assembly 6 includes a swing arm 601 that rotates at one end of the detection roller 5 and a hydraulic rod 602 for driving the swing arm 601 to rotate. The swing arm 601 is L-shaped, and the middle part of the swing arm 601 rotates on the inner wall of the housing 1 through a connecting shaft. The detection roller 5 rotates at the upper end of the swing arm 601, and the hydraulic rod 602 is hinged to the lower end of the swing arm 601. The lower end of the hydraulic rod 602 is hinged to the bottom of the housing 1.

[0037] It is understandable that the hydraulic rod 602 works, thereby driving the swing arm 601 to rotate through the connecting shaft, so that the swing arm 601 adjusts the position of the detection roller 5, which can adapt to tires of different diameters, so that the detection roller 5 can come into contact with tires of different diameters.

[0038] Specifically, two detection rollers 5 are respectively fixed with a second brake wheel 7 at their ends that are far apart from each other, and a second brake pad 8 that cooperates with the second brake wheel 7 is fixed on the top of the housing 1. The second brake pad 8 is an arc shape that matches the diameter of the second brake wheel 7.

[0039] Understandably, when a vehicle needs to leave the inspection platform, the hydraulic rod 602 drives the swing arm 601 to rotate, thereby causing the swing arm 601 to move the inspection roller 5 upward, pushing the wheel to rise and assisting the vehicle to leave between the first roller 102 and the second roller 103. To avoid the rotation of the roller affecting the friction with the wheel, a second brake wheel 7 and a second brake pad 8 are provided. When the inspection roller 5 moves upward, the inspection roller 5 drives the second brake wheel 7 to abut against the surface of the second brake pad 8, thereby braking the rotation of the inspection roller 5, making it easier to generate greater friction between the wheel and the inspection roller 5, and making it easier for the wheel to rotate and leave between the first roller 102 and the second roller 103.

[0040] In this invention, during vehicle inspection, the wheel is driven between the first roller 102 and the second roller 103. Simultaneously, the hydraulic rod 602 drives the swing arm 601 to rotate, causing the inspection roller 5 to contact the wheel surface, thus enabling vehicle inspection. When it is necessary to move the vehicle off the inspection platform, the electric push rod 406 pushes the connecting block 404 upward, causing the two connecting arms 405 to automatically adjust their angles. This causes the two connecting arms 405 to push the two first brake pads 402 away from each other, so that the first brake pads 402 contact the surface of the first brake wheel 401, thereby synchronously braking the first roller 102 and the second roller 103. Since the two sets of first rollers 102 and second rollers 103 are connected by coupling 2, the other set of first rollers 102 and second rollers 103 can be braked synchronously. This makes it easier to generate greater friction between the first rollers 102 and second rollers 103 and the wheel. At the same time, the detection roller 5 is driven to move upward by the hydraulic rod 602, which lifts the wheel. When the detection roller 5 drives the second brake wheel 7 to abut against the surface of the second brake pad 8, the rotation of the detection roller 5 is braked. This makes it easier to generate greater friction between the wheel and the detection roller 5, which makes it easier for the wheel to rotate and drive away from the first roller 102 and second roller 103.
