Description

Technical Field

[0002] With the booming development of new energy vehicles and their continuous growth in ownership, the characteristics of motor vehicle pollutant emissions have become more complex. As exhaust emission standards become increasingly stringent, the contribution of non-exhaust particulate matter from motor vehicles to atmospheric particulate matter is gradually increasing, especially with the promotion of new energy vehicles making non-exhaust particulate matter pollution a more prominent issue. Non-exhaust particulate matter emissions refer to particulate matter emissions related to vehicle operation other than exhaust emissions, such as tire wear particles, road wear particles, road resuspension particles, and brake wear particles. Compared with traditional vehicles, although new energy vehicles reduce exhaust emissions, they may lead to an increase in non-exhaust particulate matter emissions, especially in urban areas with high vehicle density and activity intensity. Strengthening research on testing non-exhaust particulate matter emissions from motor vehicles can provide technical support for reducing their harm to the urban atmospheric environment and human health, and has significant scientific importance and substantial social benefits.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figure 1-2 This utility model provides a non-exhaust emission test bench, comprising:

[0025] Collection tank 1, with mounting bracket 2 horizontally slidably connected to the top surface of collection tank 1;

[0026] A linear motion assembly is installed in the collection tank 1 and is used to control the linear movement of the mounting frame 2;

[0027] The wear mechanism includes two symmetrically arranged mounting arms 3, which are V-shaped. The mounting frame 2 is rotatably connected to the top of the mounting frame 2. The ends of the mounting arms 3 are respectively rotatably connected to the mounting shafts 4. The friction wheel 6 is fixedly connected to one of the mounting shafts 4. The top surface of the collection tank 1 is equipped with a control component, which is used to control the rotation of the mounting arms 3.

[0028] The wheel clamping fixture includes a mounting base. The wheel is rotatably connected to the top surface of the collection tank 1 through the mounting base. A transmission component is installed at one end of the collection tank 1. The transmission component is in transmission cooperation with the wheel. The friction wheel 6 is in contact cooperation with the wheel.

[0029] In operation, the wheel to be tested is rotatably connected to the top surface of the collection tank 1 via the mounting seat of the wheel clamping fixture, ensuring that the wheel is securely installed and can rotate normally. Simultaneously, the position of the mounting arm 3 in the wear mechanism is adjusted so that the friction wheel 6 is in a suitable contact position with the wheel, ready for wear testing.

[0030] The transmission component installed at one end of the collection trough 1 is activated. The transmission component works in conjunction with the wheel drive, causing the wheel to start rotating. The transmission component can be a motor that transmits power to the wheel through a transmission mechanism such as a transmission belt or gears, causing the wheel to rotate at a certain speed and torque.

[0031] The linear motion component is installed in the collection tank 1. During the test, the linear motion component controls the linear movement of the mounting frame 2. Since the mounting arm 3 in the wear mechanism is rotatably connected to the mounting frame 2, the movement of the mounting frame 2 will drive the entire wear mechanism to move in a straight line, thereby causing the friction wheel 6 to perform linear reciprocating motion on the wheel surface, simulating the wear of the wheel during actual driving.

[0032] The control component mounted on the top surface of the collection tank 1 is used to control the rotation of the mounting arm 3. During testing, the control component can be adjusted as needed to change the angle of the mounting arm 3, thereby adjusting the contact pressure and contact position between the friction wheel 6 and the wheel to simulate the wear of the wheel under different working conditions. For example, increasing the angle of the mounting arm 3 can make the friction wheel 6 apply greater pressure to the wheel, simulating heavy-load conditions; changing the rotation angle of the mounting arm 3 can adjust the contact position of the friction wheel 6 on the wheel, simulating the wear of different parts of the wheel, and tire wear particles enter the collection tank 1 for collection.

[0033] In this embodiment, a motor can be set in the mounting arm 3 to switch the friction surface of the friction wheel 6. At the same time, the whole device is controlled by a main controller (such as a PLC). A pressure sensor is set in the friction wheel 6 to monitor the pressure between it and the tire, which is used to test the particulate matter generated during the wear process of vehicle tires of different weights.

[0034] Further optimization of the scheme: the linear motion component includes a threaded rod 7, one end of which passes through the side of the collection tank 1 and is rotatably connected to the collection tank 1, and the other end of which passes through the bottom of the mounting frame 2 and is threadedly connected to the mounting frame 2. A drive motor is fixedly connected to the side of the collection tank 1, and the drive motor is axially connected to the threaded rod 7.

[0035] The design is further optimized by fixing a bearing seat 8 to the top surface of the mounting bracket 2, inserting a rotating shaft 9 at the inflection point of the two mounting arms 3, and having the rotating shaft 9 pass through the two sets of mounting arms 3 and be rotatably connected to the bearing seat 8.

[0036] A bearing seat 8 is fixedly connected to the top surface of the mounting bracket 2. A rotating shaft 9 is inserted into the inflection point of the two mounting arms 3. The rotating shaft 9 passes through the two sets of mounting arms 3 and is rotatably connected to the bearing seat 8. When the control component (whose function will be explained in detail later) applies a force to the mounting arms 3, the mounting arms 3 will rotate around the rotating shaft 9 as the axis, thereby changing the position of the mounting shaft 4 between the ends of the mounting arms 3, and thus adjusting the contact pressure and contact position between the friction wheel 6 and the wheel, simulating the wear of the wheel under different working conditions.

[0037] The scheme is further optimized. The control components include a hydraulic cylinder 10. A support plate is fixedly connected to the top surface of the collection tank 1, and the hydraulic cylinder 10 is vertically fixedly connected to the top surface of the support plate.

[0038] A support plate is fixedly connected to the top surface of the collection tank 1. A hydraulic cylinder 10 is vertically fixedly connected to the support plate, and the piston rod of the hydraulic cylinder 10 is connected to the mounting arm 3 through a connecting rod. When it is necessary to adjust the angle of the mounting arm 3, the piston rod of the hydraulic cylinder 10 extends or retracts, driving the connecting rod to move, thereby pushing or pulling the mounting arm 3 to rotate around the rotating shaft 9, changing the position of the mounting shaft 4 between the ends of the mounting arm 3, and realizing the adjustment of the contact pressure and contact position between the friction wheel 6 and the wheel, simulating different working conditions.

[0039] The scheme is further optimized. The transmission component includes a drive motor. The output shaft of the drive motor is fixedly connected to a drive pulley 11. The wheel is rotatably connected to the mounting base through a support shaft. A driven pulley 12 is mounted on the support shaft. The drive pulley 11 and the driven pulley 12 are driven by a belt 13. A mounting plate 5 is fixedly connected to the end of the collection tank 1. The drive motor is fixedly connected to the mounting plate 5.

[0040] The scheme is further optimized by fixing four sets of guide plates inside the collection tank 1. The four sets of guide plates are arranged in a truncated pyramidal structure. The threaded rod 7 passes through one of the guide plates. A discharge hole is opened at the bottom of the collection tank 1, and the discharge hole is located between the four sets of guide plates.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0042] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
