Embodiment Construction

[0047] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.

[0048] The application provides a leaf spring suspension bench test device, such as Figure 5 to Figure 10 As shown, it includes a test bench 1, a first bracket assembly 2, a second bracket assembly 3, a leaf spring to be tested 4, a connecting block 5, a saddle bolt 6 and a nut; the fatigue testing machine used in this application is a commonly used Hydraulic servo testing machine for vertical loading only.

[0049] Both the first bracket assembly and the second bracket assembly are fixed on the test bench; the test bench can be fixed on the ground or other work benches.

[0050] The leaf spring to be tested includes a main spring an...

Abstract

The present invention relates to a plate spring suspension bench test device. The device comprises a test bench, a first support assembly, a second support assembly, a plate spring to be tested, a connection block, a u bolt and a nut. The first support assembly and the second support assembly are fixed on the test bench, and the plate spring to be tested includes a main spring and an auxiliary spring. The plate spring suspension bench test device can perform bench test while satisfying the suspension key components, and is simple in structure and can reduce lots of test periods and test cost. The plate spring suspension bench test device can verify the matching rationality of the whole suspension system and solve the disadvantage and deficiency of the current auxiliary spring glue cushion bench test to allow the bench test to be reasonable and more approach to the state of an actual vehicle. The plate spring suspension bench test device performs test in the same work condition to facilitate the comparison of the life of each component.

Description

technical field [0001] The invention belongs to the technical field of detection, in particular to a leaf spring suspension bench test device. Background technique [0002] Suspension is to transmit all forces and moments acting between the wheel and the frame or body, and to ease the impact load transmitted from the uneven road to the frame or body, and to attenuate the vibration of the bearing system caused by it, so as to ensure the smooth running of the car. drive. [0003] The key components of the suspension system should have sufficient reliability to ensure the safety of the vehicle. In the process of automobile development, the requirements for component reliability verification are getting higher and higher, and the verification is completed through vehicle and component bench tests. [0004] Compared with the vehicle test verification, the component bench test has short cycle, low cost and strong pertinence, so the bench test is usually used for the verification...
