Description

Technical Field

[0001] The utility model relates to the technical field of suspension test benches, in particular to a suspension durability test bench with an adjustable angle. Background Art

[0002] Automobile suspension is an important component to ensure ride comfort. At the same time, automobile suspension, as a force transmission component connecting the frame (or body) and the axle (or wheel), is also an important component to ensure the safety of automobile driving. Therefore, automobile suspension is often listed as an important component in the technical specification table of the car. As one of the indicators to measure the quality of the car, each automobile manufacturer needs to conduct durability tests on suspension components during the process of automobile research and development, trial production, and mass production, so as to provide solutions or technical support points for improvement of automobile suspension design. Among the existing technologies, a test bench is used to perform durability fatigue tests on automobile suspension, but this technology has disadvantages: the test bench can only perform vertical reciprocating mechanical motion on the suspension structure alone, which theoretically simulates the situation where the car keeps driving in a straight line. However, when the car is driving on the road, the tire cannot keep rotating in a straight line all the time. The suspension on the tire will have different angles of inclination to ensure the normal driving of the vehicle, which leads to incomplete compliance with the experimental test data, thereby affecting the analysis and judgment of relevant personnel. For this reason, a suspension durability test bench with adjustable angle is proposed. Utility Model Content

[0028] Among them, a wheel 7 is threadedly connected to one side of the suspension 6. The suspension 6 is an assembly structure. The suspension 6 includes structures unique to the suspension 6, such as shock absorbers, shock-absorbing springs, upper swing arm assemblies, and lower swing arm assemblies. The suspension 6 and the wheel 7 constitute a quarter chassis structure of the car in order to simulate the driving condition of the vehicle. The entire suspension system of the vehicle is not used to facilitate the experiment and avoid a bloated experimental environment and additional variables.

The two ends of the sliding rod 13 are slidably connected with the first arc hole 1501, and the clamping ring 1302 is clamped in the adjusting member. Inside the adjusting member 15, the sliding rod 13 is completely limited as a whole between the two adjusting members 15, and the additional limiting disc 1301 can further stabilize the position of the sliding rod 13 to prevent factors such as structural rigidity from affecting the positioning, thereby affecting the accuracy of the experimental data.

According to the experimental requirements, a wrench is used to rotate and unscrew the first nut 14, and the adjusting member 15 is cut at a certain angle, and the first nut 14 is tightened again. Then, the second nut 22 is rotated and unscrewed with a wrench. Under the action of the damping bearing 21, the second circular plate 19 is rotated at this time.
