Description

A wet clutch brake simulation test bench device Technical Field

[0001] This utility model relates to clutch brake testing technology, specifically a wet clutch brake simulation test bench device. Background Technology

[0002] A wet clutch utilizes hydraulic pressure to engage the clutch. During the clutch disengagement and full engagement, it also includes a transmission device that controls the driving force while there is relative rotation. Unlike a dry clutch, a wet clutch mainly relies on hydraulic pressure and is generally used in automatic transmissions and continuously variable transmissions (CVTs) where high smoothness is required.

[0003] However, some wet clutch brakes are quite heavy. During testing, the wet clutch brake is usually fixed horizontally on the ground, and workers use external testing equipment to test its performance. However, wet clutch brakes are mounted vertically on the vehicle frame. The above testing method cannot simulate the actual working environment of wet clutch brakes, resulting in a large error in the test results of wet clutch brakes. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this utility model provides a wet clutch brake simulation test bench device, which can vertically install wet clutch brakes, simulate the actual working conditions of wet clutch brakes, and improve the test effect and test accuracy.

[0006] Preferably, the transmission unit includes a reduction gearbox, a main shaft, and a rotating shaft. The end of the main shaft is connected to a brake. The reduction gearbox contains a reduction gear set, which connects the main shaft and the rotating shaft.

[0007] Preferably, the rotating shaft is fitted with a bearing, the bearing is disposed in a bearing housing, and the bearing housing is fixed to the base.

[0008] Preferably, the test assembly includes a pulley block and a support plate. The pulley block is connected to a rotating shaft. A steel wire rope is wound around the pulley block. A hook is provided at the bottom end of the steel wire rope. The hook hooks a convex ring. The convex ring is fixed to a pull plate. Connecting ropes are provided around the pull plate. The bottom end of the connecting rope is fixed to the support plate.

[0009] Preferably, the tray is provided with a plurality of weight plates.

[0010] Preferably, the testing component is an eddy current dynamometer, and the output shaft of the eddy current dynamometer is coaxial with the rotating shaft.

[0011] In summary, this utility model achieves the following technical effects:

[0012] The wet clutch brake simulation test bench of this utility model adopts a base, which allows the brake to be set vertically to simulate the actual installation state. In addition, it is equipped with a transmission unit and test components, which can apply load to one side of the brake to simulate the actual working conditions, improve the test effect and test accuracy.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0022] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0023] Example 1:

[0024] As shown in Figures 1-2, a wet clutch brake simulation test bench device includes a base 1. The base 1 has mounting flanges 2 and test components on both sides. The mounting flanges 2 are vertically arranged and are used to vertically fix the brake 3. The base 1 is provided with a transmission unit, which connects the test components and the brake 3. The test components are used to apply loads to the brake 3.

[0025] A force sensor is installed on the base 1, which is connected to the wire rope 9 to display the load in real time, making it easy for testers to observe.

[0026] The wet clutch brake 3 simulation test bench device of this embodiment uses a base 1, which allows the brake 3 to be set vertically to simulate the actual installation state. In addition, the transmission unit and test components are set up to apply load to one side of the brake 3 to simulate the actual working conditions, improve the test effect and test accuracy.

[0027] The transmission unit includes a reduction gearbox 5, a main shaft 4, and a rotating shaft 6. The end of the main shaft 4 is connected to the brake 3. The reduction gearbox 5 is equipped with a reduction gear set, which connects the main shaft 4 and the rotating shaft 6. The reduction gearbox 5 is also the actual working condition, because in actual use, the brake 3 is also connected to the power source through the reduction gearbox 5.

[0028] The rotating shaft 6 is fitted with a bearing, which is located inside the bearing seat 7 and fixed to the base 1.

[0029] The test assembly includes a pulley block 8 and a support plate 10. The pulley block 8 is connected to a rotating shaft 6. A steel wire rope 9 is wound around the pulley block 8. A hook 11 is provided at the bottom end of the steel wire rope 9. The hook 11 hooks a convex ring. The convex ring is fixed to a pull plate. Connecting ropes are provided around the pull plate. The bottom ends of the connecting ropes are fixed to the support plate 10. Several weight plates 12 are provided on the support plate 10.

[0030] In use, first fix the brake 3 to the base 1 via the mounting flange 2 and connect it to the main shaft 4. Then hook the hook 11 onto the convex ring so that the support plate 10 is placed. Then place the weight plate 12 on the support plate 10 to test the braking performance of the brake 3.

[0031] Example 2:

[0032] Compared to Embodiment 1, the difference in this embodiment is that, as shown in Figure 3, the test component is an eddy current dynamometer 13, and the output shaft of the eddy current dynamometer 13 is coaxially arranged with the rotating shaft 6.

[0033] The eddy current dynamometer 13 generates resistance through an electromagnetic field, which can achieve high-precision load control. This method is fast and accurate, and is suitable for measuring the load response of the brake 3 in a short time.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
