Description

Technical Field

[0001] The utility model relates to a durability test bench for automobile chassis parts, belonging to the technical field of automobile chassis detection. Background Art

[0002] The durability test of automobile chassis parts is an important means to evaluate the stability and service life of automobile chassis parts under various complex road conditions and usage conditions. The main purpose of the test is to ensure that the chassis parts can maintain their performance and functions in various usage scenarios, so as to ensure the safety and reliability of the whole vehicle. Automobile chassis parts mainly consist of a transmission system, a running system, a steering system and a braking system. When conducting various durability tests on the brakes in the braking system, the cooperation of a test bench is required.

[0003] The existing Chinese patent with the publication number CN219038383U proposes a brake bench test tooling based on a MacPherson suspension. The device installs chassis suspension parts and shock absorbers through attachment points designed to be the same as those of the actual vehicle, achieving complete coverage of the suspension parts. The symmetric structure design meets the requirement of arbitrary switching between left and right during bench tests. At the same time, the screw device on the strut assembly cooperates with the rubber support to adjust the compression state of the shock absorber under different loads, achieving the purpose of testing under different load suspension states of the vehicle.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the protection scope of the present utility model.

[0027] Referring to Figure 1 and Figure 2 , a durability test bench for automotive chassis parts includes a base 1. Two chutes 11 are symmetrically formed on the upper surface of the base 1. A slider 12 is slidably installed in the chute 11. A mounting seat 2 is fixedly connected to the slider 12. A rubber pad 3 is detachably installed on the mounting seat 2 and the height of the rubber pad 3 is adjustable. Two sets of mounting components 4 for installing shock absorbers are slidably installed on the base 1 in a direction approaching or departing from each other. A driving component 5 for driving the two sets of mounting components 4 to slide is installed on the base 1. The mounting component 4 is correspondingly arranged with the mounting seat 2 and is fixedly connected through a connecting component 10.

[0028] During use, the automotive chassis subframe is connected to the base 1 and locked with bolts and nuts of corresponding specifications. The base 1 is provided with holes for cooperating with the bolts, which are not shown in the figure. The lower swing arm of the automotive chassis subframe is supported by the rubber pad 3. The shock absorber is installed on the mounting component 4, and then the shock absorber and the automotive chassis parts are connected by a brake, so that the entire suspension becomes an integral body. In this embodiment, the mounting component 4 is composed of a screw device and a pressure rod, and the composition structure of the screw device is the same as the principle and working mode of the screw device in the Chinese patent "A Brake Bench Test Tooling Based on MacPherson Suspension" with the publication number CN219038383U, and will not be elaborated here.

[0029] Referring to Figures 1 - 4 , the driving component 5 includes a first sliding seat 51, a second sliding seat 52, a threaded rod 53, a guide rod 54, a first driving member 55, a second driving member 56 and a column 57. The first sliding seat 51 and the second sliding seat 52 are respectively fixed on two opposite side walls of the base 1. The threaded rod 53 is rotatably installed in the first sliding seat 51 and one end extends out of the first sliding seat 51 and is connected with a crank 14. The threads on both sides of the outer end of the threaded rod 53 are opposite. The guide rod 54 is arranged in the second sliding seat 52. Two first driving members 55 and two second driving members 56 are correspondingly installed. The two first driving members 55 are respectively threadedly connected to both sides of the threaded rod 53. The second driving member 56 is slidably arranged on the guide rod 54. Columns 57 are installed on the tops of the first driving member 55 and the second driving member 56. The two columns 57 are connected through a welding mounting plate 13. The mounting component 4 is installed on the mounting plate 13.

[0030] Further, both the first slide base 51 and the second slide base 52 are H-shaped rods, and both the first driving member 55 and the second driving member 56 are E-shaped blocks. The only difference between the first driving member 55 and the second driving member 56 is that the middle part of the first driving member 55 is a threaded hole for cooperating with the threaded rod 53, and the middle part of the second driving member 56 is a through hole for the guide rod 54 to pass through. One side opening of the first slide base 51 and the second slide base 52 faces the base 1. Installation grooves 6 are provided at the tops of the first slide base 51 and the second slide base 52. The threaded rod 53 and the guide rod 54 are both installed in the installation grooves 6. Specifically, one end of the threaded rod 53 is rotatably installed in the installation groove 6 through a bearing, and a through hole is provided at the other end of the installation groove 6 for connecting the crank 14. One side of the first driving member 55 and the second driving member 56 slides on the base 1. Movement grooves 7 for the first driving member 55 and the second driving member 56 to slide are provided on the base 1. The movement grooves 7 enable the first driving member 55 and the second driving member 56 to move freely, thereby realizing the change of position.

[0031] Further, H-shaped blocks 8 are welded and fixed on the inner walls on both sides of the first driving member 55 and the second driving member 56. The openings on both sides of the H-shaped blocks 8 are arranged vertically, and at least one moving wheel 9 is installed in each of the openings on both sides. In this embodiment, preferably two moving wheels 9 are installed in a single opening. Due to the shape characteristics of the H-shaped rods of the first slide base 51 and the second slide base 52, there are two concave grooves. The moving wheels 9 can roll in the concave grooves. On the one hand, the rolling of the moving wheels 9 improves the stability of the column 57 during movement. At the same time, the friction between the first driving member 55 and the second driving member 56 and the H-shaped rods during movement can be reduced, which is more conducive to the manual operation and adjustment by the staff.

[0032] Referring to Figure 1 and Figure 3 , the connecting component 10 includes a fixed sleeve 101 and a connecting rod 102. There are two fixed sleeves 101 and two connecting rods 102. The two fixed sleeves 101 are respectively welded and fixed on the tops of the first driving member 55 and the second driving member 56. The column 57 is inserted into the fixed sleeve 101 with an interference fit. One end of the connecting rod 102 is inserted into the fixed sleeve 101 and the other end is inserted into the mounting seat 2, and the end of the connecting rod 102 connected to the mounting seat 2 is fastened by a bolt.

[0033] Further, a screw rod is integrally formed on the side of the rubber pad 3 facing the mounting seat 2. A threaded hole (not shown in the figure) for threadedly cooperating with the screw rod is provided on the mounting seat 2. The rubber pad 3 can move up and down on the mounting seat 2 through the threaded cooperation between the screw rod and the threaded hole and can be locked at any position, so that the height of the rubber pad 3 can be adjusted according to the installation requirements of the automotive chassis parts to complete the support of the chassis parts.

[0034] The working principle of a durability test bench for automotive chassis parts of the present utility model is as follows:

[0035] When conducting durability tests by installing automotive chassis components for different wheelbases, such as shock absorbers, brakes, and chassis subframes, the staff rotates the crank 14 to drive the threaded rod 53 to rotate. Since opposite threads are symmetrically arranged on the threaded rod 53 and under the guiding and limiting of the guiding rod 54, the rotation of the threaded rod 53 causes a pair of driving members 55 that cooperate with the threaded rod 53 to move relative to each other, thereby changing the distance between the two opposite driving members 55. Additionally, since mounting plates 13 are provided at the tops of two longitudinally adjacent columns 57, and mounting assemblies 4 are provided on the mounting plates 13, the movement of the driving members 55 can cause the two columns 57 to move, thereby changing the distance between the two mounting assemblies 4. At the same time, as the columns 57 move, since a connecting rod 102 is connected to the column 57 through a fixing sleeve 101, the connecting rod 102 is fixedly connected to the mounting seat 2, and the mounting seat 2 is slidably engaged with the base 1, the mounting seat 2 can be caused to move as the column 57 moves.

[0036] The above are only the preferred embodiments of the present invention, and do not impose any formal or substantial limitations on the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the premise of the present invention, several improvements and supplements can still be made, and these improvements and supplements should also be regarded as the protection scope of the present invention. All those who are familiar with this professional technology, without departing from the spirit and scope of the present invention, when making some minor changes, modifications, and equivalent changes in the evolution using the technical content disclosed above, are all equivalent embodiments of the present invention; at the same time, all changes, modifications, and evolutions made to the above embodiments based on the substantial technology of the present invention in any equivalent manner still fall within the scope of the technical solutions of the present invention.
