Problems solved by technology

In recent years, some suspension test rigs have been used individually in the test, but the disadvantages of such suspension test rigs are: the structure is more complicated, the accuracy is not high, and the vertical direction, horizontal direction and longitudinal loading in the horizontal direction cannot be carried out at the same time. test
The current suspension load spectrum calibration test requires a set of test rigs for suspension loading, but there is no such test rig at present. A test rig that can load the suspension system upwards can meet the requirements of the vertical loading test of the automobile suspension system.

specific Embodiment 1

[0029] A kind of suspension loading test bench of the present invention, please refer to Figure 1 to Figure 5 The relevant figures in the middle include a weighing platform 1 and a load-bearing platform 2 located below the weighing platform 1. The weighing platform 1 is erected on the load-bearing platform 2. The function of the load-bearing platform 2 is to bear the suspension system and the weighing platform 1. and transmit the vertical upward loading force of the actuating element 3 located below it. The function of the weighing platform 1 is to carry the suspension system, and at the same time transmit the vertically loaded force of the suspension. The concrete load-bearing platform 2 includes an upper plate 21, a lower plate 22, and a support column 24 between the upper plate 21 and the lower plate 22. The function of the support column 24 is to support the upper plate 21, the upper plate 21 and the weighing platform 1 At least two load cells 4 are evenly arranged. The ...

specific Embodiment 2

[0030] A kind of suspension loading test bench of the present invention, please refer to Figure 1 to Figure 5 In the relevant figures, it is also possible to set a freely slidable slide plate 5 on the upper surface of the weighing platform 1 on the basis of the specific embodiment one. The slide plate 5 is an upper and lower layer structure, and the lower layer of the slide plate 5 is fixed on the weighing platform 7. , Balls are provided between the lower floor and the upper floor of the slide plate 5, the upper floor slides freely on the balls, and the upper floor and the lower edge can be connected by elastic bands. The slide plate 5 is provided with a horizontal plane, and the suspension system is arranged on the horizontal plane of the slide plate 5. Since the slide plate 5 is arranged on the weighing platform 1, the setting of the slide plate 5 makes it possible to carry out other small machines or components of the suspension system. Weighing and loading load calibrati...

specific Embodiment 3

[0031] A kind of suspension loading test bench of the present invention, please refer to Figure 1 to Figure 5 In the relevant figures, on the basis of the specific embodiment 1 and the specific embodiment 2, four load cells 4 can be evenly arranged between the upper plate 21 and the weighing platform 1, and four load cells 4 can be set. The advantage of the sensor 4 is that the measurement is more accurate in this way, and the accuracy of the calibration is improved. A further preferred solution is to set a load cell 4 between the upper plate 21 and the weighing platform 1 at each of the four corners of the upper plate 21, thus ensuring that the four load cells 4 are The uniform setting also ensures the stability of the suspension system on the weighing platform 1, further improving the accuracy of measurement and calibration. Further, the weighing platform 1 and each of the load cells 4 are connected by bolts. The advantage of such a connection method is that the paralleli...

Abstract

The invention discloses a hanger bracket loading test platform comprising a weighing platform and a bearing platform positioned below the weighing platform. The bearing platform comprises an upper flat plate, a lower flat plate and a supporting upright column arranged between the upper and the lower flat plates. At least two weighing sensors are evenly arranged between the upper flat plate and the weighing platform. An acting element is positioned below the center of the lower flat plate. The top end of the acting element for lifting or descending the bearing platform and the weighing platform is contacted with the center of the lower flat plate. The hanger bracket loading test platform has reasonable structure, can measure a vertical upward load demarcated by a hanger bracket real vehicle status and a part status, obtains accurate data, and realizes convenient and practical loading, simple adjustment, convenient maintenance and stable and reliable performance.

Description

technical field [0001] The invention relates to a test bench, in particular to a suspension loading test bench. Background technique [0002] The automobile suspension is responsible for the important task of supporting the car body and ensuring the smooth and safe driving. In order to improve the performance of the suspension system, people often adopt the method of optimizing the suspension parameters. In recent years, some suspension test rigs have been used individually in the test, but the disadvantages of such suspension test rigs are: the structure is more complicated, the accuracy is not high, and the vertical direction, horizontal direction and longitudinal loading in the horizontal direction cannot be carried out at the same time. test. The current suspension load spectrum calibration test requires a set of test rigs for suspension loading, but there is no such test rig at present. A test rig that can load the suspension system upwards can meet the requirements of...
