Description

Technical Field

[0001] The present application relates to the technical field of vehicle test benches, and in particular to a vehicle sideslip test bench. Background Art

[0002] Currently, during vehicle development and testing, testing a vehicle's sideslip performance is a crucial step in ensuring vehicle safety. As equipment simulating sideslip conditions, the rationality of the sideslip test bench's structural design and test accuracy directly impact the accuracy and reliability of the test results. Traditional vehicle sideslip test benches typically utilize fixed rails and a sliding platform, with a motor driving the sliding platform to slide on the rails. While this type of test bench can simulate sideslip conditions, the fixed connection between the rails and the platform limits flexibility and adaptability during testing.

[0003] Existing side-slip test benches suffer from complex structures, high maintenance costs, and limited test range. Simulating different road conditions and side-slip angles requires frequent adjustments to the rail position or replacement of rails of different specifications, which is cumbersome and inefficient.

In particular, when simulating different road conditions and sideslip angles, frequent adjustments to the slide rail position or replacement of slide rails of different specifications are required, resulting in cumbersome and inefficient operations.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a vehicle sideslip test bench, comprising a base, wherein two groups of mounting grooves are provided inside the base, and four groups of sliding grooves are provided inside the base, and both sides of each group of mounting grooves are connected to the two groups of sliding grooves, and multiple groups of mounting holes are provided inside each group of sliding grooves, and adjustment grooves are provided above each group of sliding grooves, and the adjustment grooves are connected to the mounting holes, and multiple groups of slide rail assemblies are installed inside the two groups of mounting grooves, and the slide rail assemblies include slide rails and two groups of first mounting blocks, and the two groups of first mounting blocks are located on both sides of the slide rails, and the first mounting blocks are slidably connected The interior of the sliding groove is connected to the interior of the first mounting block, and a fixing groove is provided inside the fixing groove. A fixing rod is installed inside the fixing groove, one end of the fixing rod passes through the adjustment groove and extends to the outside, and the other end of the fixing rod passes through the fixing groove and is connected to the mounting hole. A sliding platform is slidably connected to the top of the slide rail assembly, and multiple groups of sliding blocks are installed at the bottom of the sliding platform. The interiors of the multiple groups of sliding blocks are provided with sliding grooves matching the slide rails. A protective shell is installed above the middle of the base, and multiple groups of hydraulic presses are installed inside the protective shell. The output ends of the multiple groups of hydraulic presses are connected to one side of two groups of sliding platforms.

[0006] By adopting the above technical solution and setting up a slide rail assembly, when in use, the sliding platform can be driven by a hydraulic press to slide on the outside of the slide rail through the sliding block at the bottom to realize the sliding platform's detection of the vehicle's sideslip data.

By pulling out the fixing rods on both sides at the same time, the slide rail can be moved back and forth. When moving to the specified position, the bottom of the fixing rod can be connected to the mounting hole to achieve the fixing effect. When the angle of the slide rail needs to be changed, the angle of the slide rail can be changed by moving the fixing rod on one side.
