Abstract
A high-speed train connecting sleeper beam comprises an anti-S-shaped damper base and an anti-lateral-twisting pull rod base. Square pins and round pin positioning guiding installing holes, all of which are connected with a train body are formed in end side beams. The high-speed train connecting sleeper beam is characterized in that the connecting sleeper beam is of an integral casting box structure, an integral cavity is formed in the middle of the connecting sleeper beam and serves as an additional air chamber for air springs, strengthening ribs are arranged on the upper plane, and the inner cavity of the connecting sleeper beam is composed of transverse casting bars and longitudinal casting bars. According to the connecting sleeper beam, the strength of the connecting sleeper beam is guaranteed, manufacturability and air tightness are good, the weight is low, and the strength is high. The simplicity of mounting and dismounting of a bogie and the train body is achieved, the monopoly from the foreign technology is broken, and cost is reduced.
Description
Technical field
The present invention relates to a kind of rolling stock technical field, particularly a kind of contact sleeper beam being applied to EMU.
Background technology
Contact sleeper beam is bogie truck secondary suspension device, link between draw gear and car body, bears and transmit the various load between bogie truck and car body.Also as the auxiliary chamber that air spring system bogie truck is housed, facilitate the maintenance maintenance of bogie truck, reduce and use cost.
At present, due to the domestic casting experience not having similar products, therefore, the contact sleeper beam that Highs-speed motor train unit bogie adopts is all the cast aluminium alloy structure from external import, and cost is very high, increases the productive costs of enterprise.In addition, import sleeper beam is echelon form housing, and sleeper beam need bear the load from car body, and the stress after sleeper beam is connected with car body is comparatively concentrated, is easy to cause sleeper beam stress damage and shorten its service life.Given this plant situation, a kind of satisfied contact sleeper beam required that uses of research and design is imperative.
Summary of the invention
The object of this invention is to provide a kind of weight-saving, effectively avoid stress to concentrate, improve the motor train unit casting contact sleeper beam of leak tightness and intensity.
For achieving the above object, the invention provides a kind of EMU contact sleeper beam, comprise anti-snakelike shock absorber bearing, anti-side turns round draw-bar seat, end side bar is provided with the square cotter, the round pin positioning and guiding mounting hole that are connected with car body, it is characterized in that: contact sleeper beam is inblock cast body structure, is complete cavity in the middle of contact sleeper beam, as the auxiliary chamber of air bellow, upper plane is provided with reinforced rib, and contact sleeper beam inner chamber is formed by casting horizontal bar and casting longitudinal rib.
Middle reinforced rib is longer than the reinforced rib of both sides.
The upper end of end side bar is respectively equipped with cast recess.
It is inblock cast body structure that the present invention contacts sleeper beam, upper plane is provided with reinforced rib, and inner chamber adopts casting horizontal bar, longitudinal rib structure, and upper plane is provided with reinforced rib, realize contact sleeper beam intensity to ensure, good manufacturability, air-tightness is good, and quality is light, intensity is high, achieve the simplification that bogie truck and car body are installed and dismantled, and broken the monopolization of foreign technology, reduce cost.

Detailed description of the invention
With reference to Fig. 1, contact sleeper beam belongs to thin-walled multi-cavity foundry goods, and complex structure, wall thickness great disparity position is many and length dimension large, and whole casing bears deadlight load, and inner chamber is the auxiliary chamber of air bellow.On contact sleeper beam, the casting horizontal bar of the reinforced rib of plane and inner chamber, casting longitudinal rib jointly realize contact sleeper beam main body intensity and ensure, middle reinforced rib is longer than the reinforced rib of both sides.Cavity can inventory of gas, and all cavitys interpenetrate.Side bar is simultaneously for the secondary suspension parts such as anti-snakelike shock absorber, anti-side rolling torsion rod provide interface, side bar is the main load bearing component of contact sleeper beam, and the load of bearing mainly comprises vertical force, the application force of anti-side rolling torsion rod, the application force and two of anti-snakelike shock absorber are the application force of vertical damper.Side bar is respectively equipped with and is connected square cotter mounting hole seat, round pin mounting hole seat with car body, shock absorber mount pad, for installing location and anti-snakelike shock absorber, to realize contacting the good process that sleeper beam and car body are assembled.Process 4 car body communication ports outside side bar, connected together by bolt and vehicle body bottom frame, make bogie truck and car body form an entirety.Middle part arranges traction seat, is connected with bogie pivot, mainly bears longitudinal loading and transverse load.Contact sleeper beam both sides are provided with sky spring abutment, are connected for empty spring make-up gas with air bellow navel.Empty spring abutment processes M8 tapped bore, when avoiding lifting air bellow navel with contact sleeper beam and be separated.Contact sleeper beam side bar and middle part processing drain gutter, can emptying contact sleeper beam in moisture.Can be used as endoscope check auxiliary hole simultaneously.Side bar end is respectively equipped with installation groove, is separated with car body to facilitate contact sleeper beam.Contact sleeper beam side is provided with grounding base, upper anti-overcharge valve seat, height valve seat, pressure switch seat, emergency valve seat.Grounding base is for installing bogie truck grounding jumper; Pressure switch seat is used for the connection of all bogie truck pressure switch pipelines, when pressure reports fault lower than train BCU during specified value; Emergency valve seat is used for all bogie truck safety valves and installs, and opens safety valve when pressure exceedes specified value.Relief valve seat is for installing overflow-valve device, by pass valve composition Main Function ensures that head Che Yiwei end is under what circumstances all higher than “A” end of car, namely during an end bogie truck air bellow fault exhaust, can be vented immediately “A” end of car bogie truck air bellow by overflow-valve device, guarantee that a car remains that an end is higher than “A” end of car, avoid a Che Yiwei to hold bottom equipment to contact with rail.Anti-overcharge valve seat, for installing anti-overcharge valve, prevents Altitude control defective valve space-time gas spring from overcharging.The casting of contact sleeper beam adopts Alternative hole technique, opens organize auxiliary hole, so that sand removal more in contact sleeper beam bottom surface.After casting machine cleaning inner chamber, the needs that sprue welds to meet structure are dosed to auxiliary hole.
