Description
Technical field
The present invention relates to a kind of bogie truck of guideway vehicle, particularly relate to a kind of bogie truck registration device of guideway vehicle, belong to field of mechanical technique.
Background technology
Bogie truck is one of parts of paramount importance in guideway vehicle structure, and its Main Function is as follows: 1) vehicle adopts bogie truck be for increase vehicle load-carrying, length and volume, improve train running speed, to meet the needs of Transportation Development; 2) ensure under normal operating conditions, car body can reliably be seated on bogie truck, makes wheel be converted into along the rolling of rail the translation that car body runs along circuit by bearing arrangement; 3) support car body, bear and between transmitting from car body to wheel or from wheel track to car body between various load and application force, and make axle heavily uniform distribution.4) ensure vehicle safety run, can neatly linearly circuit run and be smoothly through curve.5) structure of bogie truck will be convenient to the installation of spring damper, makes it to have good damping behavior, to relax the interaction between vehicle and circuit, reduces vibration and impacts, reducing dynamic stress, improving vehicle smoothness and safety.6) make full use of the adhesion between wheel track, transmitting tractive power and braking force, amplify the braking force that brake cylinder produces, make vehicle have good braking effect, to ensure to stop within the distance of regulation.7) bogie truck is an individual components of vehicle, reduces connector at bogie truck as far as possible between car body.Positioning arm is fifth wheel to the critical component of axle box and frame apparatus, at present, bogie truck positioning arm used mostly is split-type structural, mainly comprise the parts (as the patent No. 200620034960.0, the Chinese utility model patent of title " Wide rail welding bogie ") such as positioning arm, journal box body and clamping band, the shortcoming of Split type structure is that unsprung weight is heavier, constituent part is more, decompose packaging technology complicated, at substantial manpower and materials, production efficiency is low.
Summary of the invention
The object of the invention is the defect existed for prior art, a kind of bogie truck integral type positioning arm of proposition, alleviates bogie truck unsprung weight, improves safety and stability.
The present invention is technical solution problem by the following technical programs: bogie truck integral type positioning arm, comprise sleeve shaft side bearing press mounting hole, one side neck facing epitaxy of described axle end bearing press mounting hole stretches out connecting arm, described connecting arm end has an integrated set section point press mounting hole with it, it is characterized in that: the cuboid frame-shaped that the bottom of described axle end bearing press mounting hole has to downward-extension does not fall to taking turns Xuan interface, the described side not falling to taking turns Xuan interface connects with described connecting arm, it is away from the opposite side of connecting arm, cylinder mask along described axle end bearing press mounting hole has outward extending symmetrical baffle plate, the end of described symmetrical baffle plate takes the shape of the letter U, outward opening, it is vertical bumper mount pad that each end has one, the top of described axle end bearing press mounting hole has protruding cylinder, described cylinder is socketed spring bowl, there is between described spring bowl and axle end bearing press mounting hole the lifting backstop extended obliquely upward, described lifting backstop and described symmetrical baffle plate are positioned at the same side neck face of axle end bearing press mounting hole, the fourth class office of the periphery of described axle end bearing press mounting hole has circular hole.
The described bottom surface not falling to taking turns Xuan interface in said structure has circular port.Described baffle plate has arc-shaped side.Described one be vertical bumper mount pad is cuboid, and pedestal center has mounting hole.Described lifting backstop has horizontal flanging.The diameter of described axle end bearing press mounting hole is greater than the diameter of a set section point press mounting hole.
During use, the present invention is directly press-fited on wheel spindle device axle head solid box; Carry one is vertical damper mount pad and does not fall to taking turns Xuan interface, and structure is simple; Adopt bogie truck of the present invention, one is that adjustment is very convenient, need be only add adjusting pad between spring at positioning arm spring bowl and one, without the need to removing wheel set axle box device and being separated positioning arm node and truck frame.
This invention simplifies journal box body and clamping band, structure is more simply compact, can directly press-fit on axle head solid box, and total constituent part is little, decompose, assembling easily, adjust easy to maintenance, can Simplified flowsheet and frock greatly.In addition, its project organization is simple, can adopt inblock cast, realizes lightweight and low cost while ensureing structural safety reliability.The more important thing is, adopt integral type positioning arm to realize the whole lightweight taken turns registration device, effectively can alleviating bogie truck unsprung weight and be about 80kg, when guaranteeing good comfort level, being conducive to improving safety and stability.Can be used as a kind of mature structure scheme to be widely used in rail traffic vehicles bogie truck system.
