Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically to an electronically controlled adjustable damper durability test bench. Background Technology

[0002] Shock absorbers are automotive components used to suppress the oscillations caused by the rebound of springs after absorbing shocks and to absorb impacts from the road surface. As the requirements for driving comfort become increasingly higher, the adjustability of shock absorbers is becoming more and more important. Against this backdrop, electronically controlled damping adjustable shock absorbers have emerged. Compared with traditional passive shock absorbers, electronically controlled damping adjustable shock absorbers can dynamically adjust the damping in real time and optimize it for different driving scenarios, taking into account both vehicle handling performance and driving comfort. At the same time, electronically controlled damping adjustable shock absorbers are also more outstanding in terms of energy consumption and durability, and have greater advantages in intelligent integration.

[0003] Vibration damper durability testing benches are used for vibration simulation experiments of automotive vibration dampers. They can simulate the vibration of vibration dampers when a car is driving on a real road surface, thereby verifying the fatigue durability of the vibration dampers. During durability testing of vibration dampers, heat dissipation is necessary. Existing technologies often employ a full immersion cooling method in vibration damper durability testing benches, such as the patent titled "Multi-station Vibration Damper Durability Testing Bench," which requires the vibration damper to be completely submerged in a water tank for heat dissipation. However, electronically controlled damping adjustable vibration dampers require stringent temperature control during testing, and some types cannot be fully immersed in water for heat dissipation. Therefore, existing technologies present significant problems when conducting durability tests on these types of electronically controlled damping adjustable vibration dampers. Utility Model Content

Compared with the prior art, this utility model can provide targeted heat dissipation for the vibration damper, which not only has a better heat dissipation effect but also better versatility. It can also be adapted to electronically controlled damping adjustable vibration dampers with more stringent temperature control conditions and those that cannot be completely immersed in water for heat dissipation.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] A durability test bench for an electronically controlled adjustable damping vibration damper, specifically, as follows: Figure 1 , 2 As shown, it includes: a support mechanism 1, a lateral force application mechanism 2, and a heat dissipation mechanism. The support mechanism 1 is used to fix the vibration damper and guide the movement direction of the vibration damper during durability testing. The lateral force application mechanism 2 is located on one side of the support mechanism 1 and is used to apply lateral force to the vibration damper during durability testing. The heat dissipation mechanism includes a housing 3, a liquid pump 4, and a conduit 5. The bottom of the support mechanism 1 is located inside the housing 3 and is in contact with the bottom of the housing 3. The housing 3 is filled with coolant. The liquid pump 4 is placed in the coolant and one end is connected to the conduit 5. One end of the conduit 5 is connected to the liquid pump 4, and the other end acts on the vibration damper to guide the coolant to contact the vibration damper.

[0033] In actual operation, first connect the vibration damper to the support mechanism 1, adjust the lateral force application mechanism 2 to a suitable angle, then start the lateral force application mechanism 2 to apply lateral pressure to the vibration damper, and at the same time start the heat dissipation mechanism and turn on the liquid pump 4 so that the coolant in the housing 3 is sprayed to the vibration damper through the conduit 5 to cool and reduce the temperature of the vibration damper.

[0034] In some embodiments, such as Figure 2 As shown, the lateral force application mechanism 2 described above has been optimized. In this embodiment, the lateral force application mechanism 2 includes a first support 21, a second support 22, and a force application component. The second support 22 is slidably connected to the first support 21. The force application component is connected to the second support 22 and acts on the damper to apply a lateral force to the damper.

[0035] Optionally, in this embodiment, the first bracket 21 has multiple openings along the vertical direction on its circumferential surface, and the second bracket 22 has openings on its connecting surface to the first bracket 21. The two are connected by bolts.

[0036] In actual operation, after the shock absorber and the support mechanism are installed, the second support 22 is adjusted vertically so that the force-applying component is adjusted to the predetermined position, and then the first support 21 and the second support 22 are connected together by bolts.

[0037] In some embodiments, such as Figure 2 As shown, the above-mentioned force-applying component has been optimized. In this embodiment, the force-applying component includes a force-applying cylinder 231 and a force-applying tentacle 232. The force-applying cylinder 231 is connected to the second bracket 22 and is used to provide power to the force-applying tentacle 232. The force-applying tentacle 232 is connected to the output end of the force-applying cylinder 231 and is used to apply lateral force to the shock absorber.

[0038] During actual installation, the booster cylinder 231 is fixedly connected to the side opposite to the connection between the second bracket 22 and the first bracket 21. The output end of the booster cylinder 231 is connected to the booster contact 232. A groove is provided on the opposite end face of the booster contact 232 and the output end of the booster cylinder 231. The size of the groove depends on the size of the shock absorber.

[0039] In some embodiments, such as Figure 1 , 2 As shown, the above-mentioned box 3 has been optimized. In this embodiment, the box 3 is a stainless steel box.

[0040] In some embodiments, such as Figure 1 , 2 As shown, the liquid pump 4 described above has been optimized. In this embodiment, the liquid pump 4 can adjust the flow rate of the coolant entering the conduit 5.

[0041] In actual operation, the coolant flow rate in the conduit 5 is controlled by the liquid pump 4 to achieve real-time control of the vibration damper's operating temperature. When it is necessary to control the vibration damper's operating temperature to rise, the liquid pump 4 is adjusted to reduce the coolant flow rate in the conduit 5; when it is necessary to control the vibration damper's operating temperature to fall, the liquid pump 4 is adjusted to increase the coolant flow rate in the conduit 5.

[0042] In some embodiments, such as Figure 1 ,2 As shown, the conduit 5 described above has been optimized. In this embodiment, the conduit 5 is a malleable conduit that can be bent as needed to change the spray position and direction of the coolant.

[0043] In actual operation, the conduit 5 is bent so that the nozzle of the conduit 5 is directed to the part of the shock absorber that needs to be cooled, so as to achieve precise cooling of the shock absorber.

[0044] Preferably, in this embodiment, a magnetic seat 51 is also connected to the conduit 5, which is used to adjust the position of the conduit 5 acting on the vibration damper.

[0045] In actual operation, the magnetic base 51 is attached to the wall of the housing 3 to support the guide tube 5. The surface guide tube 5 is unable to cool the vibration damper due to its own weight. When it is necessary to cool different parts of the vibration damper, the magnetic base 51 can be slid along the wall of the housing 3, which will move the guide tube 5 so that the nozzle of the guide tube 5 is pointed at the part of the vibration damper that needs to be cooled.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
