Abstract
The invention relates to a light-weight bolster for urban rail trains. A hollow square box type integral structure is used, and various weight lightening design features are adopted for parts of the bolster, so that structural rigidity and weight lightening are both considered, and running speed of urban rail trains can be increased. The bolster comprises an upper cover plate, a lower cover plate and an abdominal plate vertically connected between the upper cover plate and the lower cover plate, and the abdominal plate, the upper cover plate and the lower cover plate are welded to form the square box structure. Air-spring cushion plates and a traction pin cushion plate are welded to the surface of the lower cover plate, wherein the air-spring cushion plates are used for bearing vertical load of an integral vehicle, and the traction pin cushion plate is used for bearing longitudinal load of the integral vehicle. The abdominal plate, the upper cover plate and the lower cover plate are welded to form an integral structural frame of the bolster, and weight lightening and structural rigidity can be both well considered by means of the square box structure.
Description
Technical field
The present invention be directed to the sleeper beam structure that is applied to municipal rail train and carry out the lightweight improvement, belong to mechanical manufacturing field.
Background technology
Along with present domestic city track traffic ground is popularized rapidly and promoted, higher design and use requirement has been proposed for the sleeper beam that constitutes the car body major part.
The sleeper beam that is applied to light rail train, subway is the critical component of connection, bearing body and bogie truck, also is the major part of propulsive effort transmission between car body and the bogie truck.Existing sleeper beam adopts solid framed structure at large, and purpose is in order to increase integral rigidity, but has also increased the weight of sleeper beam self from the another side, is unfavorable for light-weighted car body design and improves train running speed.
And sleeper beam is comparatively concentrated with the stress after draw beam, the side bar of car body underframe are connected, and is easy to cause the sleeper beam stress damage and shortens its service life.
Also there is comparatively defective such as complicacy of sleeper beam and miscellaneous part (like corrugated floor) connection structure in addition, thereby causes the anxiety of installing space under the car, be unfavorable for realizing the compact design and the layout of equipment and parts under the car.
Summary of the invention
Municipal rail train of the present invention is used the lightweight sleeper beam; The shape of the mouth as one speaks box integral structure that is to solve the problem of above-mentioned prior art existence and takes a kind of hollow; On its parts, take multiple light-weight design characteristic, thereby reach the rigidity of structure and weight-saving is taken into account.
The objective of the invention is to, under the prerequisite that guarantees the sleeper beam rigidity of structure and Joint strenght, realize light-weight design to greatest extent, be beneficial to improve the moving velocity of municipal rail train.
Another goal of the invention is that the stress area after enlarging sleeper beam and draw beam, side bar being connected is in the hope of improving the stress damage degree.
Goal of the invention also is, realizes installing space design plan under a kind of car of simple structure.
For realizing the foregoing invention purpose, described municipal rail train mainly includes with the lightweight sleeper beam:
Upper cover plate, lower cover, and be connected upper cover plate and the lower cover web between vertical;
Web and upper cover plate, lower cover constitute the box-structure of the shape of the mouth as one speaks through welding;
Be useful on empty spring backing plate that bears the car load vertical load and the towing pin backing plate that is used to bear the car load longitudinal loading in the lower cover surface soldered.
Like above-mentioned essential characteristic, through welding the integral structure framework that web, upper cover plate and lower cover constitute sleeper beam, the box-structure of this shape of the mouth as one speaks can be taken into account the lightweight and the rigidity of structure preferably.
Be local stiffness and the load-carrying capacity that improves above-mentioned shape of the mouth as one speaks box-structure further, the innovative approach that can take is between web, upper cover plate and lower cover, to be welded with the gusset that several are used to increase local stiffness.
Carry out welding operation for improving being connected, being convenient between upper cover plate and the gusset, on upper cover plate, offer the cover plate slotted hole of several gussets that are used to peg graft.
Further the scheme of refinement light-weight design is on web and gusset, to offer several slotted holes respectively.
In addition, also can on empty spring backing plate and towing pin backing plate, offer several circular holes.
In order to solve the problem of stress concentration of connection structure more obviously, effectively, sidepiece or end at upper cover plate and lower cover are respectively arranged with outstanding arc sections, and arc sections is used for sleeper beam and is connected to reduce stress concentration with draw beam, side bar.
Comparatively embodiment preferred is, is coated with coat of paint at the integral surface of sleeper beam, to improve the antiseptic effect of sleeper beam.
Be welded with the angle bar ⊥ type, that be used to weld corrugated floor in sleeper beam single-piece both sides, with the coat of paint on protection sleeper beam surface.Promptly when the weld seam that is welded to connect between angle bar and the corrugated floor, can guarantee that coat of paint is not destroyed.
Content to sum up, municipal rail train of the present invention has the following advantages and beneficial effect with the lightweight sleeper beam:
1, through taking the shape of the mouth as one speaks box integral structure of hollow, realizes the rigidity of structure of sleeper beam and taking into account of light-weight design.
2, under the prerequisite that guarantees the sleeper beam Joint strenght, help improving train running speed through light-weight design.
3, improved the sleeper beam problem of stress concentration effectively, thereby reduced the stress damage degree and effectively increase the service life.
