Problems solved by technology
After studying various forms of bogies, technicians found that there are some technical defects in traditional bogies, such as: large self-weight, resulting in large force on wheel sets, large wear of wheel and rail, and large noise; rigidity of frame Connection, poor vibration damping ability, resulting in greater vibration of the carriage, poor ride comfort; large wheel load reduction rate, reducing safety; poor anti-rolling ability makes the carriage prone to rollover, vertical buffer capacity Insufficiency leads to greater vibration of the cabin and poor ride comfort, higher self-weight leads to lower traction efficiency, and lower assembly efficiency due to unreasonable component installation layout, etc.

The embodiment of the invention provides a bogie and a rail vehicle. The bogie comprises: a cross beam which extends in the transverse direction; two secondary suspension mounting seats symmetricallyarranged on the top surface of the cross beam, wherein an installation channel penetrating in the longitudinal direction is formed between the secondary suspension installation base and the cross beam, and the longitudinal direction and the transverse direction are two horizontal directions which are perpendicular to each other; and side beams extending in the longitudinal direction, wherein the number of the side beams is two, and the two side beams are arranged side by side and are arranged in the installation channels in a penetrating mode respectively. According to the bogie middle cross beam, the side beams are of independent structures, the size is small, production, transportation and assembly are easy, and the assembly efficiency can be improved.
Description
technical field [0001] The present application relates to rail vehicle running technology, in particular to a bogie and a rail vehicle. Background technique [0002] Rail vehicles are an important transportation link connecting cities, and have gradually become the main means of transportation in cities. Rail vehicles are also the main carrier for cargo transportation. A rail vehicle mainly includes: a car body and a bogie arranged under the car body. The bogie is used to carry the car body and realize the running and steering functions. [0003] The bogie includes structures such as frame, wheelset, traction device, buffer device, etc. The frame includes two side beams extending along the length of the vehicle and a beam connecting the two side beams. The connection between the beam and the side beams is as follows: many kinds of. After studying various forms of bogies, technicians found that there are some technical defects in traditional bogies, such as: large self-weig...
