Embodiment Construction

[0009] An automobile suspension coil spring durability test device, comprising a fixed bracket 10 connected to one end of the coil spring A and a movable bracket 20 connected to the other end of the coil spring A, the movable bracket 20 is connected to a driving mechanism 30, and the driving mechanism 30 is connected to There are at least two sets of movable brackets 20 and coil springs A, so that some coil springs A perform stretching motion while the rest of the coil springs A perform compression motion. Because the coil spring A has the function of energy storage, the law of energy conservation and the principle of action and reaction force are cleverly used, and at the same time, multiple coil spring A tests can be completed in one test, so the test efficiency is almost doubled and the test cycle is shortened. , reducing costs.

[0010] Such as figure 1 As shown, the drive mechanism 30 includes a variable frequency motor 31, the output shaft of the variable frequency moto...

Abstract

The object of the present invention provides an automotive suspension spiral spring durability test device. The device shortens the test period and improves the test efficiency. Meanwhile, the cost is low. The device comprises a fixed bracket and movable brackets. The fixed bracket is connected with one end of a spiral spring A. The movable brackets are connected with the other end of the spiral spring A. The movable brackets are connected with a driving mechanism. The driving mechanism is connected with at least two groups of movable brackets and the spiral spring A. One part of the spiral spring A conducts the stretching movement, while the other part of the spiral spring A conducts the compression movement. According to the technical scheme of the invention, the spiral spring has the energy storage effect, and skillfully utilizes the energy conservation law and the acting force and counter-acting force principles. Meanwhile, a plurality of spiral spring tests can be conducted through a single test. Therefore, the test efficiency is almost doubled, and the test period is shortened. The cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile product testing, in particular to an automobile suspension coil spring durability test device. Background technique [0002] As a part of the car suspension, the coil spring is connected to the car body and the wheel knuckle, which eases the impact on the car body. The strut assembly plays an extremely important role in driving comfort and maneuverability, and can ensure a good driving experience for users. Experience that enhances the car's brand. If the coil spring fails, it will cause the center of gravity of the vehicle to shift, the vehicle's handling will be reduced, and the comfort will be reduced. Therefore, the durability of the coil spring is an important detection index in the design and manufacture process. Contents of the invention [0003] The purpose of the present invention is to provide an automobile suspension coil spring durability test device, which can shorten the test ...
