Description

Technical Field

[0001] This utility model relates to the technical field of vehicle springs, specifically a testing device for rubber herringbone springs used in rail vehicles. Background Technology

[0002] The background technology of the testing device for rubber herringbone springs in rail vehicles stems primarily from the high performance requirements of vehicle suspension systems. As a key component of the suspension system, the rubber herringbone spring directly affects the vehicle's running smoothness, safety, and comfort. Traditional testing methods suffer from low efficiency and insufficient accuracy, making it difficult to meet the demands of modern rail vehicles for high-performance springs. Therefore, developing an efficient and accurate testing device is essential. This device comprehensively tests the stiffness, fatigue life, deformation, and other properties of the rubber herringbone spring by simulating actual working conditions, ensuring its reliability and durability in practical applications, thereby improving the overall performance of rail vehicles.

[0003] Application number CN201220741758.7 discloses a testing device for rubber herringbone springs for rail vehicles, including a base, a left V-shaped support, a right V-shaped support, a V-shaped pressure seat, a limiting block, and a tightening frame. The left and right V-shaped supports are symmetrically fixed on the base. The limiting block is fixed on the concave V-shaped mating surface of the left and right V-shaped supports. The rubber herringbone springs for rail vehicles are placed in the left and right V-shaped supports. The V-shaped pressure seat is placed between the two rubber herringbone springs for rail vehicles. The tightening frame is set at the upper end of the left and right V-shaped supports. With this structural test bench, all vibration damping performance tests of the rubber herringbone springs for rail vehicles can be completed with just one installation. It can also more objectively simulate the stress state of the rubber herringbone springs in actual use, making the test data more realistic and accurate. However, there are shortcomings. When the device is in use, when materials need to be tested, they must first be manually added one by one. This requires a certain amount of labor cost and has a certain degree of inefficiency when performing compression tests. Utility Model Content
