The invention provides an elastic side bearing, a bogie and a railway vehicle. The elastic side bearing comprises a side bearing seat and an elastic side bearing body arranged in the side bearing seat, and a top plate is fixedly connected to the top of the elastic side bearing body. The elastic side bearing is characterized in that the elastic side bearing body consists of a cylindrical primary rigid elastic body and at least two rigid elastic bodies, the secondary rigid elastic bodies are peripherally and uniformly arranged on the primary rigid elastic body, each secondary rigid elastic body consists of an outer support, a middle elastic body and an inner support which are sequentially fixedly and integrally arranged, and the lower end of the primary rigid elastic body is exposed out of the secondary rigid elastic bodies. The elastic side bearing in the scheme has double rigidity, stability and dynamics performances of the elastic side bearing are improved, and further, running reliability of a bogie and running reliability of a railway vehicle are enhanced. Besides, the elastic side bearing is in a split structure, so that components of the elastic side bearing can be independently replaced when damaged, resources are saved, and the service cost is reduced.
Description
technical field [0001] The invention relates to rail vehicle technology, in particular to an elastic side bearing, a bogie and a rail vehicle. Background technique [0002] Rail vehicles generally include car body, bogie, brake device, coupler buffer device and other parts. Among them, the function of the bogie is to support the car body, guide the vehicle to run along the track, and bear various loads from the car body and the line. The car body and the bogie are connected as a whole through the center plate and side bearings. The center plate mainly bears the vertical load; there are mainly two kinds of side bearings, one is the gap (rigid) side bearing, and the other is the elastic side bearing. The side bearing also has the effect of preventing the side swing angle of the car body from being too large. At the same time, it also provides a stable turning resistance moment between the car body and the bogie, which improves the stability of the vehicle and can increase th...
