Abstract

The utility model relates to a 70% low floor light rail unpowered bogie which is characterized in that a side beam is formed by a Z-shaped transition piece and three sections of square tubes in a welding mode. A secondary spring base of a cantilever beam structure is welded on the outer side of the Z-shaped transition piece of the side beam of a bogie framework. According to the 70% low floor light rail unpowered bogie, the Z-shaped transition piece is adopted, therefore, the square tubes on the end portion and the middle of the side beam of the framework are effectively connected, the bigger vertical height difference on the end portion and the middle of the side beam is further achieved, and the reduction of the base plate face of a 70% low floor light rail middle vehicle is guaranteed. A secondary spring installation base of the cantilever beam structure is further welded on the Z-shaped transition piece of the outer side of the side beam, the secondary spiral spring height is effectively improved, the hanging rigidity is reduced, and meanwhile the longitudinal span of two secondary steel springs on one side of the bogie is larger.

Description

70% low floor light rail unpowered bogie
Technical field
The present invention relates to a kind of 70% low floor light rail unpowered bogie.Relate in particular to the lower low floor vehicle unpowered bogie of a kind of centre unpowered module hull bottom plate face height.
Background technology
Present domestic existing, the light rail of successfully realizing commercial operation, only Changchun Light Rail is very few, but in the middle of its unpowered bogie, unpowered module base plate face height is inconsistent, can't satisfy the consistent and lower requirement of modern low floor vehicle low country base plate face height.
Summary of the invention
For satisfying the domestic and international market to the tight demand of modern low-floor light rail vehicle, the foreign mature experience, by change steering structure shelf structure and secondary suspension structure, develop go out a kind of guarantee in the middle of the unpowered bogie of basically identical and novel 70% low-floor light rail vehicle that whole height is lower of unpowered module base plate face height.
For achieving the above object, the invention provides a kind of 70% low floor light rail unpowered bogie, it is characterized in that: curb girder adopts zigzag transition piece and three sections square tubes solderings; The secondary spring seat of cantilever beam structure is welded on outside truck frame curb girder zigzag transition piece.
The present invention adopts the zigzag transition piece, has not only effectively connected the square tube at truck side sill end and middle part, has also realized the larger vertical diff-H at curb girder end and middle part, guarantees the reduction of the middle car bottom plate face of 70% low floor light rail.Be welded with equally the secondary spring mount pad of cantilever beam structure on the zigzag transition piece of the curb girder outside, effectively to improve two be the coil spring height, also make two two of bogie truck one side when reducing suspension stiffness is that the vertical span of steel spring is larger.
Description of drawings
Fig. 1 structural representation of the present invention;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 framework schematic diagram of the present invention;
Fig. 4 secondary suspension device schematic diagram.
The specific embodiment
With reference to Fig. 1, Fig. 2, unpowered bogie mainly is comprised of truck frame 1, independent axle Biodge device 2, single stage suspension device 3, secondary suspension device 4, central traction apparatus 5, foundation brake rigging 6, bogie truck accessory equipment 7.
With reference to Fig. 3, adopt zigzag transition piece 8, not only effectively connected the square tube 10 at truck side sill end 9 and middle part, also realized the larger vertical diff-H at curb girder end and middle part, guarantee the reduction of the middle car bottom plate face of 70% low floor light rail.
With reference to Fig. 4, be welded with equally the secondary spring mount pad 11 of cantilever beam structure on the curb girder outside, zigzag transition piece, effectively improving two is coil spring 12 height, and also making two two of bogie truck one side when reducing suspension stiffness is that the vertical span of steel spring 12 is larger.
