The invention discloses a steering frame and a framework thereof. The framework comprises transverse beams (4), side beams (3), air-spring mounting bases (1), longitudinal beams (5) and air-spring supporting beams (2) arranged on the outer sides of the side beams (3), wherein the air-spring mounting bases (1) are arranged on the air-spring supporting beams (2); the transverse beams (4) are steel tubes of transverse beams; each air-spring supporting beam (2) is provided with an inner cavity communicated with an inner channel of the corresponding transverse beam (4); and an additional air chamber of an air spring is formed of the inner cavity of each air-spring supporting beam (2) and the inner channel of the corresponding transverse beam (4). According to the invention, the number of parts of the steering frame is decreased, and the mounting spaces of air springs are enlarged, so that air springs with large spans can be used, and the damping effect is improved; because the additional air chamber is formed of the inner cavity of each air-spring supporting beam and the inner channel of the corresponding transverse beam, the volumes of the air chambers are increased, the stiffness of the air springs is effectively reduced, the damping of the air springs is improved, and the damping effect is further improved.
Description
technical field [0001] The invention relates to the technical field of EMU equipment, in particular to a bogie and its frame. Background technique [0002] At present, damping springs are installed on the bogies of EMUs to reduce the vibration between the wheels and the carriages and improve ride comfort. The main type of vibration damping spring is air spring, which is widely used due to its short filling time and good vibration damping effect. [0003] However, due to the large number of parts on the bogie and the limited installation position, the installation space of the air spring is small, thus limiting its vibration damping effect. [0004] Therefore, how to improve the vibration damping effect is an urgent problem to be solved by those skilled in the art. Contents of the invention [0005] In view of this, the present invention provides a frame to improve the vibration damping effect. The present invention also provides a bogie with the above frame. [0006] T...
