Secondary suspension mechanism for rail locomotive vehicle
A technology for secondary suspension and rail locomotives, which is applied in the direction of the lateral relative moving device between the underframe and the bogie, can solve the problems of many installation nodes, high maintenance costs, and many maintenance parts, etc., and achieves fewer installation nodes. And the effect of good disassembly and assembly process and simple design structure

Problems solved by technology
The traditional secondary suspension mechanism has the following disadvantages: 1. Both the bogie and the car body must be provided with a separate vertical stop structure, which must be tightened with bolts. The operation is more complicated, and the locomotive needs to be disassembled and maintained regularly; 2. The structure is more complicated , there are many installation nodes, and problems are more likely to occur during disassembly and assembly; 3. There are more parts to be repaired during operation and maintenance, and the repair cost is higher

The invention provides a secondary suspension mechanism for a rail locomotive vehicle. The secondary suspension mechanism comprises a spring upper seat, a secondary spring and a spring lower seat. Thespring lower seat is welded to a frame as a part of the frame, and a spring lower plate seat is installed above the spring lower seat. A lower stop is installed above the spring lower plate seat, thesecondary spring sleeves the lower stop, one end of the secondary spring is in contact connection with an adjustment pad, and the other end of the secondary spring is in contact connection with the spring upper seat. An upper stop is fixedly installed under the spring upper seat and is located inside the secondary spring, and a stop gap is formed between the upper stop and the lower stop. The secondary suspension mechanism for the rail locomotive vehicle is simple in structure, vertical stop structures are not needed to be arranged on a bogie nor a vehicle body separately, bolt fastening is not needed, and maintenance is not required, so that manufacturing and maintenance costs are reduced.
Description
technical field [0001] The invention belongs to the field of rail vehicle suspension systems, in particular to a secondary suspension mechanism for rail vehicles. Background technique [0002] At present, the secondary suspension mechanism of the locomotive mainly consists of secondary springs, upper and lower rubber pads, vertical stops on the bogie and vertical stops on the car body. The secondary springs are installed in series between the frame and the car body through the upper and lower rubber pads, and the secondary vertical stops are installed on the frame and the car body with bolts. Each frame is provided with a vertical stop on the left and right beams. The upper and lower rubber pads are made of steel welded and vulcanized rubber. In order to ensure the positioning of the rubber pads on the frame and car body, positioning pins are designed on the mounting surfaces of the upper and lower rubber pads. The main body of the secondary vertical stop is steel plate and ...
