Description

Technical Field

[0001] The utility model relates to the technical field of real vehicle bogie testing, in particular to an intelligent operation and maintenance testing system for a real vehicle bogie. Background Art

[0002] The real vehicle bogie refers to the bogie used in the actual vehicle. It is an independent running structure composed of wheel sets, frame (or side frame), spring damping device, basic brake device, etc., used to support the vehicle body and rotate relative to the vehicle body. The design and use of the real vehicle bogie has an important impact on the driving stability, safety and comfort of the vehicle.

[0003] The real vehicle bogies of trains and high-speed railways are one of the core components of rail vehicles. They play an important role in supporting vehicles, guiding vehicles, and reducing vibrations. Bogies are usually composed of side frames or frames) wheelsets, axle boxes, spring dampers, basic brakes, etc. The bogie supports the entire vehicle body through its structure and spring dampers to ensure the stability of the vehicle during driving. The bogie bears and transmits various loads and forces from the vehicle body to the wheels or from the wheel rail to the vehicle body to ensure that the train can run smoothly under various road conditions. When the vehicle passes through a curve, the bogie can guide the vehicle to run along the curved track and reduce the resistance of the vehicle when passing through the curve. The spring damper installed on the bogie can absorb the impact and vibration between the wheels and the track, improving the comfort of riding.

[0004] However, when testing the actual vehicle bogie, the main components of the bogie are usually disassembled, and the components consisting of the wheelset, axle box device, and primary suspension are tested separately, which makes it impossible to effectively apply vertical loading to simulate the weight of the car. Only no-load tests can be performed, and anti-snaking tests during the operation of the bogie cannot be performed. Other suspension tests cannot be coupled, and active or passive tests of the bogie cannot be performed. In view of this, the present application proposes an intelligent operation and maintenance test system for the actual vehicle bogie. Utility Model Content
