During the operation of the vehicle, the wear resistance of bearings may be different under working conditions of different temperatures, pressures, speeds and corrosive environments. Therefore, it is of great significance to test the wear resistance of automobile bearings under different working conditions to ensure their good performance under actual working conditions, which is of great significance to ensure the safe, reliable and efficient operation of the vehicle.

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

[0051] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0052] like Figures 1 to 10 As shown, the wear resistance detection device of automobile parts of the present invention includes: a clamping and friction module 1, used for clamping and rubbing the bearing shell; an adjustment module 2: used for real-time detection and adjustment of temperature; an adding module 3: used for adding and mixing additives; a control module 4; the additives include: lubricants, corrosive agents or water; the lubricant is lubricating oil, the corrosive agent is water vapor or inorganic acid, and the inorganic acid is sulfur dioxide or sulfur trioxide.

[0053] During actual operation, the bearings may be exposed to an environment containing moisture, especially under high humidity conditions; moisture may also be mixed into the lubricating oil, which can cause oxidation reactions on the bearing surface, leading to corrosion. In addition, crankcase blowby or combustion of high-sulfur fuels may produce inorganic acids, which accumulate on the bearing surface and aggravate bearing corrosion; in particular, the chloride ions contained in the inorganic acids have a particularly obvious corrosive effect on the bearings; all of these situations may shorten the life of the bearings. Therefore, when performing friction tests on bearings, if only friction tests are performed, the test errors may differ greatly from those in actual use due to the reduction of the effects of moisture and corrosive agents on the bearings, making it difficult to simulate the working conditions during actual operation.

[0054] The clamping friction module 1 includes: a mounting block 11 for mounting a bearing, a friction member 12 for the friction bearing, a mounting seat 13 for mounting the mounting block 11, a telescopic cylinder 14 for driving the mounting seat 13 to slide, and a motor 15 for driving the friction member 12 to rotate; an arc-shaped mounting groove is provided on the inner wall of the mounting block 11, and a connecting hole matching the bearing is provided on the mounting groove, which is used to cooperate with the bolt to mount the bearing in the mounting groove; the friction member 12 is cylindrical, and the friction member 12 is coaxially arranged with the mounting groove; the mounting block 11 is slidably connected with the mounting seat 13, and the mounting groove can slide along the radial direction of the mounting seat 13; the telescopic cylinder 14 is arranged along the width direction of the machine, and the piston rod of the telescopic cylinder 14 is fixedly connected with the mounting seat 13, which is used to drive the mounting seat 13 to move closer to or away from the friction member 12.

[0055] The adjustment module 2 includes: a temperature sensor 22 for detecting the ambient temperature before testing and detecting the bearing temperature in real time during testing, and a simulation component 21 for simulating the engine temperature; the simulation component 21 includes: an arc-shaped limit plate 211, a liquid guide pipe 212 connected to the convex side of the arc-shaped limit plate 211, and a liquid supply unit 213 for supplying liquid to the liquid guide pipe 212; the liquid supply unit 213 is composed of a liquid storage tank 2131 and a circulation pump 2132 connected to the liquid storage tank 2131; the liquid guide pipe 212 is composed of a liquid outlet pipe and a return pipe.

[0056] The arc limit plate 211 is composed of a large arc plate 2111, a small arc plate 2112 slidably connected to the concave side of the large arc plate 2111, and a telescopic chamber 2113 arranged between the large arc plate 2111 and the small arc plate 2112; the liquid outlet pipeline, the telescopic chamber 2113, and the return pipeline are connected in sequence; when the circulating pump 2132 is started, the liquid in the liquid storage tank 2131 flows through the telescopic chamber 2113 through the liquid outlet pipeline, and then flows back to the liquid storage tank 2131 through the return pipeline.

[0057] When the circulation pump 2132 is started, the telescopic chamber 2113 is filled with liquid. When the liquid inflow rate of the telescopic chamber 2113 is greater than the liquid outflow rate, the telescopic chamber 2113 expands and increases. On the one hand, the contact area between the coolant in the telescopic chamber 2113 and the arc-shaped limit plate 211 is increased, thereby improving the cooling effect. On the other hand, during the expansion of the telescopic chamber 2113, the small arc-shaped plate 2112 is driven to squeeze the installation groove, thereby driving the bearing to squeeze the friction part 12, thereby increasing the pressure between the bearing and the friction part 12. On the contrary, when the liquid inflow rate of the telescopic chamber 2113 is less than the liquid outflow rate, the expansion degree of the telescopic chamber 2113 decreases, thereby driving the installation groove to slide in the opposite direction, thereby driving the bearing away from the friction part 12, thereby reducing the pressure between the bearing and the friction part 12 until the bearing and the friction part 12 are separated.

[0058] As an optional solution of this embodiment, a solenoid valve 314 may also be installed at the liquid outlet end of the telescopic chamber 2113 to adjust the liquid outlet volume.

[0059] The telescopic cavity 2113 includes: a telescopic body, the mounting end of the telescopic body is fixedly mounted on the concave side of the large arc plate 2111, and the telescopic end of the telescopic body is mounted on the convex side of the small arc plate 2112; a reset member 21131 is connected between the large arc plate 2111 and the small arc plate 2112 of the telescopic body, and the reset member 21131 is a spring, an elastic rope, etc.; the telescopic body is preferably made of polyurethane elastomer, shape memory polymer or polyvinyl chloride, so that it can automatically reset when the internal pressure of the telescopic cavity 2113 is reduced.

[0060] A pressure sensor 21132 for real-time pressure detection is also provided between the telescopic cavity 2113 and the small arc plate 2112; the flow rate at the liquid inlet end of the telescopic cavity 2113 is adjusted by a circulating pump 2132 in the liquid supply unit 213; the circulating pump 2132 is electrically connected to the control module 4. For example: when the telescopic cavity 2113 needs to be expanded, the output power of the circulating pump 2132 is increased, so that the water accumulated in the telescopic cavity 2113 increases and expands, thereby squeezing the mounting seat 13, thereby driving the bearing bush to approach the friction member 12, and increasing the friction force; when the telescopic cavity 2113 needs to be reduced, the output power of the circulating pump 2132 is reduced, so that the water accumulated in the telescopic cavity 2113 decreases or expands slightly, thereby increasing the distance between the bearing bush and the friction member 12, and reducing the friction force.

[0061] The real-time pressure measured by the pressure sensor 21132 is set to P, and the output power of the circulation pump 2132 is set to ΔP; since the liquid in the telescopic chamber 2113 will fluctuate when it flows, the fluctuation factor α is set; when the output flow rate increases, the pressure increases, and the proportional coefficient between the real-time pressure P and the output power ΔP is set to k; then the output power of the circulation pump 2132 is: ΔP= (P-α) / k.

[0062] When the liquid in the telescopic cavity 2113 flows, it may cause the telescopic cavity 2113 to fluctuate, and then cause the measured real-time pressure P to fluctuate. Therefore, it is necessary to reduce the impact of the fluctuation on the real-time pressure P. The present application includes the following method: first, the measured real-time pressure data is sorted by size, and the maximum and minimum values ​​are excluded to reduce the impact of extreme values; then, the pressure data after elimination is processed by moving average filtering to reduce the impact of random noise; and the average value is designated as the real-time pressure P.

[0063] When the output power ΔP is fixed, the proportional coefficient k remains unchanged, and the output real-time pressure P is fitted into a curve in the coordinate system along the time axis; the change of the curve is analyzed, the change rate of the curve is determined, and the fluctuation of the real-time pressure P is analyzed according to the change rate. After multiple tests, the real-time pressure P is substituted into the above formula to obtain the fluctuation factor α. After the fluctuation factor α is obtained, adjust ΔP to increase or decrease, and record ΔP1, ΔP2, ΔP3, ..., ΔP n , and record the corresponding implementation pressures P1, P2, P3, ..., P n , substitute each ΔP and the corresponding P value into the above formula respectively; obtain the value range of the proportional coefficient k; wherein, when the telescopic chamber 2113 expands to the maximum, the output power ΔP is increased, and the change of the implementation pressure P is no longer related to the proportional coefficient k. After multiple tests, the maximum value range of the output power ΔP can be obtained.

[0064] The adding module 3 includes: an adding tank 31 for adding additives, and a mixing assembly 32 for mixing additives. The adding tank 31 is composed of a first adding tank 311 for adding lubricating oil, a second adding tank 312 for adding corrosive agents, and a third adding tank 313 for adding water, which are connected in sequence. The first adding tank 311, the second adding tank 312, and the third adding tank 313 are all provided with liquid outlets, and each liquid outlet is connected to a solenoid valve 314 for controlling the liquid output.

[0065] The mixing assembly 32 includes: a mixing chamber 321, a mixing element 322, and a power source 323 for driving the mixing element 322 to mix; the power source 323 is preferably a motor 15; a liquid inlet is provided on the outer wall of the small arc plate 2112, and a liquid outlet is provided on the concave side of the small arc plate 2112; the liquid inlet end of the mixing chamber 321 is connected to the liquid outlet of the adding box 31, and the liquid outlet end of the mixing chamber 321 is connected to the liquid inlet of the small arc plate 2112 via a connecting piece 324.

[0066] The connecting member 324 includes: a connecting tube 3241, a swing plate 3242 installed on the inner wall of the connecting tube 3241, an auxiliary plate 3243 for limiting the swing plate 3242, a return spring 3244 for driving the swing plate 3242 to return to its original position, and an airbag 3245 for inflating air into the connecting tube 3241; the airbag 3245 is installed on the outer wall of the connecting tube 3241 and is connected to the connecting tube 3241, and the air outlet of the airbag 3245 is located on the air inlet side of the swing plate 3242; the auxiliary plate 3243 is located on the air inlet side of the movable end of the swing plate 3242 Air side; the airbag 3245 contacts the outer wall of the telescopic chamber 2113; when the circulating pump 2132 is started, the circulating pump 2132 drives the telescopic chamber 2113 to expand, and the expansion of the telescopic chamber 2113 squeezes the airbag 3245, so that the airbag 3245 is inflated into the connecting tube 3241, thereby increasing the pressure in the connecting tube 3241, thereby forcing the swing plate 3242 to swing, and causing the mixed liquid in the connecting tube 3241 to spray out, thereby adjusting the concentration of the initial additive, and then adjusting the initial lubricant concentration, the initial corrosive agent concentration and the initial humidity.

[0067] In this embodiment, the connecting pipe 3241 is also connected to a fan or a water pump for real-time adjustment of the fluctuating concentration of the additive.

[0068] It can be seen from the above description that when the circulating pump 2132 of the present application is started, the liquid in the liquid storage tank 2131 flows out from the telescopic chamber 2113, thereby adjusting the temperature of the arc limit plate 211; at the same time, the expansion degree of the telescopic chamber 2113 can be adjusted by adjusting the output power of the circulating pump 2132, thereby adjusting the pressure between the bearing and the friction part 12; when the telescopic chamber 2113 expands, it can also compress the airbag 3245 and spray the mixed additives of the mixing assembly 32 through the small arc plate 2112, thereby adjusting the initial lubricant concentration, the initial corrosive agent concentration and the initial humidity.

In order to cover these situations, the temperature threshold range of the liquid supply unit 213 can be set to: 70°C to 150°C; the concentration of corrosive agents in lubricating oil is generally low, but it is necessary to consider the situation of high sulfur fuel, etc. The specific value needs to be set according to the actual corrosive environment that may occur, and the threshold range of corrosive agent concentration is 0.1% to 1%; the pressure borne by the bearing depends on the engine load and operating state; under normal circumstances, the pressure range between 10N and 50N may be more reasonable, but in some extreme working conditions, the pressure may be higher, so the threshold range of pressure is set to 10 to 60N;
