Motor suspension of urban rail vehicle

Abstract

The invention provides a motor suspension of an urban rail vehicle. The motor suspension is composed of a bottom plate 2, a vertical plate 3, a rib plate 4, a riser plate 7, installation bases 8 and a cover plate 1 through installing and welding, wherein the bottom plate 2 is of a bent structure; the bottom edge of the bottom plate 2 is welded with the vertical plate 3 being provided with the installation bases 8; the rib plate 4 being provided with a circular-arc notch is welded between the bottom plate 2 and the inner side of the vertical plate 3; the cover plate 1 being provided with the riser plate 7 is welded between the vertical plate 3 and the top of the rib plate 4; inwards-retracted positions on two sides of the vertical plate 3 and the bottom plate 2 are respectively welded with a side end plate 5 and a side end plate 6 with the same shape with the rib plate. The installed and welded structure meets the space requirements on equipment installation, interference to equipment is avoided.

Description

technical field [0001] The invention relates to a motor hanger for an urban rail vehicle, belonging to the technical field of vehicle manufacturing. Background technique [0002] The urban rail vehicle bogie has a compact structure and less space for equipment installation. In the scheme of the prior art, the motor hanger adopts the bent steel plate welding structure (see attached figure 1 , 2 ). The motor hanger must meet the EN15085 welding standard while meeting the motor installation hole pitch. The bend of the outer facade ( figure 2 Mark Ⅰ), according to the requirements of the EN15085 standard, the bending radius should be three times the thickness of the outer vertical plate, and a certain welding allowance should be left on the outside of the weld, which increases the bending radius. The width makes the lateral width of the motor hanger larger, and it is easy to cause equipment interference when the outer dimension of the foundation brake device is larger. C...
