Background technology
Bogie truck is one of parts of paramount importance in guideway vehicle structure, and its Main Function is as follows: 1) on vehicle, adopting bogie truck is load-carrying, length and volume, the raising train running speed for increasing vehicle, to meet the needs of Transportation Development; 2) guarantee under normal running (operation) conditions, car body can be seated on bogie truck reliably, by bearing arrangement, makes wheel be converted into car body along the translation of circuit operation along the rolling of rail; 3) support car body, bear and transmit from car body between wheel or from wheel track to various load and application force between car body, and make heavily uniform distribution of axle.4) guarantee vehicle safety operation, can along straight line circuit, move and be smoothly through curve neatly.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, and reduces dynamic stress, improves 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, and makes vehicle have good braking effect, stops guaranteeing within the distance of regulation.7) bogie truck is an individual components of vehicle, reduces as far as possible connector at bogie truck between car body.Positioning arm is the critical component of fifth wheel to 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, expend a large amount of manpower and materials, production efficiency is low.
Utility model content
The purpose of this utility model is the defect existing for prior art, and a kind of bogie truck integral type positioning arm of proposition, alleviates bogie truck unsprung weight, improves safety and stability.
The utility model 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 bottom of described axle end bearing press mounting hole has to the cuboid frame shape of downward-extension and do not fall to taking turns Xuan interface, a described side and the described connecting arm that does not fall to taking turns Xuan interface joins, 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, on described cylinder, be socketed spring bowl, between described spring bowl and axle end bearing press mounting hole, there is the lifting backstop of extending 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 that does not fall to taking turns Xuan interface in said structure has circular port.Described baffle plate has arc-shaped side.Described one is that 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 utility model is directly press-fited on wheel spindle device axle head solid box; What carry one is vertical damper mount pad and does not fall to taking turns Xuan interface, simple in structure; Adopt bogie truck of the present utility model, one is that adjustment is very convenient, need be only between spring, to add adjusting pad at positioning arm spring bowl and, without removing wheel to axle box device and separated positioning arm node and truck frame.
The utility model has been simplified journal box body and clamping band, and structure is more simple compact, can directly press-fit on axle head solid box, total constituent part seldom, decompose, assembling easily, adjust easy to maintenancely, can greatly simplify technique and frock.In addition, its project organization is simple, can adopt inblock cast, realizes lightweight and low cost when guaranteeing structural safety reliability.The more important thing is, adopt integral type positioning arm to realize the whole lightweight of taking turns registration device, can effectively alleviate the about 80kg of bogie truck unsprung weight, in the situation that guarantee good comfort level, be conducive to improve safety and stability.Can be used as a kind of mature structure scheme is widely used in rail traffic vehicles bogie truck system.
