Description
Technical field
The utility model relates to a kind of titanium alloy framework and bogie truck, belongs to rail traffic vehicles construction applications.
Background technology
Traditional framework adopts welding for steel structure monocoque structure, and heavier mass, anti-fatigue performance is not good, and adds noise transmission path, reduces the traveling comfort of vehicle.
Chinese invention patent application CN201310491256.2 discloses a kind of curb girder of truck frame, the curb girder body of this curb girder made by carbon fiber composite material.This truck side sill is box cavity body structure, and the framves such as motor, gear case, brake equipment are suspended on bogie truck crossbeam, and structure is also complicated, and antifatigue and traveling comfort are not good.Simultaneously, because truck transom hangs motor, gear case, brake equipment, bear live load, therefore Interface design is complicated, carrying is complicated, and carbon fiber composite material and Steel material are two kinds of diverse materials, the difficulty that links together is large, and carbon fiber Interface design and to bear fatigue property poor, therefore truck transom must retain original steel design, the connection difficulty of carbon fiber composite material and steel design, cost is high.
Utility model content
In order to overcome the deficiency of existing welding for steel structure ture technology, the utility model aims to provide a kind of titanium alloy framework and bogie truck, and this framework and bogie truck can realize the object of vehicle lightweight and low noise.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of titanium alloy framework, comprises two curb girders and the crossbeam being connected two curb girders, and these two curb girders are connected in I shape with crossbeam; Its constructional feature is, described curb girder and crossbeam are the beam body that titanium alloy is made.
Thus, curb girder and crossbeam adopt titanium alloy to make, and alleviate the overall weight of framework on the one hand, also greatly reduce noise simultaneously.
Be below the technical scheme of further improvement of the utility model:
In order to improve the structural strength of framework further, described curb girder and crossbeam are formed in one structure, and thus, framework is integral structure, and structural strength is high.
Preferably, described titanium alloy is alpha+beta titanium alloys or beta-titanium alloy.Further, described alpha+beta titanium alloys is Ti-6Al-4V, Ti-15Mo-3Al-3Sn-3Cr, Ti-21Nb-14Al or Ti-24Al-14Nb-3V-0.5Mo.Described beta-titanium alloy is Ti1023 or Ti153.
In described alpha+beta alloy, Ti+6Al+4V Alloyapplication is the most extensive.More than 50% is had to have this composition in the titanium alloy of current use, it has good Combination property, current people go deep into the most its research and receive maximum inspections, and maximum application is at aviation industry (airframe, body parts, helicopter component, jet engine parts, gas turbine engine, rocket, artificial satellite, guided missile etc.).
Beta-titanium alloy is the class titanium alloy be most widely used, and beta-titanium alloy has the highest intensity/mass ratio, and the titanium alloy component of large cross-sectional plane has very excellent intensity, toughness and anti-fatigue performance.With type alpha+beta alloy phase ratio, the weak point of beta alloy is that density is large, range of capacity is quite little, cost is more high.
Further, the utility model additionally provides a kind of bogie truck, primary spring mount pad, air bellow mount pad, motor hanger, gear box bracket and pantagraph current collector mount pad that this bogie truck comprises framework and arranges architecturally; Its constructional feature is, described framework is above-mentioned titanium alloy framework; Described primary spring mount pad, air bellow mount pad and pantagraph current collector mount pad are fixedly mounted on described curb girder, and described motor hanger, gear box bracket are fixedly mounted on described crossbeam.
Compared with prior art, the beneficial effects of the utility model are: titanium alloy framework of the present utility model, bearing various maximum perpendicular load while, transmits vertical horizontal force between wheel track, and can reach expendable weight, minimizing noise object.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of the utility model embodiment;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the front elevation of Fig. 1.
Detailed description of the invention
A kind of titanium alloy framework, as Figure 1-3, comprises two curb girders 1 and the crossbeam 2 being connected two curb girders 1, and these two curb girders 1 and crossbeam 2 are weldingly connected and entirety is I shape, and described curb girder 1 and crossbeam 2 are the beam body that alpha+beta titanium alloys or beta-titanium alloy are made.Specifically, employing alpha+beta titanium alloys is Ti-6Al-4V or Ti-15-3, as Ti-15Mo-3Al-3Sn-3Cr.
A kind of bogie truck, the primary spring mount pad 3, air bellow mount pad 4, motor hanger 5, gear box bracket 6 and the pantagraph current collector mount pad 7 that comprise framework and arrange architecturally; Described framework is above-mentioned titanium alloy framework; Described primary spring mount pad 3, air bellow mount pad 4 and pantagraph current collector mount pad 7 are fixedly mounted on described curb girder 1, thus, truck side sill is used for primary spring, air bellow etc., main vehicle and passenger weight, and bearing the longitudinal applied loading of car body, pantagraph current collector mount pad is for installing pantagraph current collector.Described motor hanger 5, gear box bracket 6 are fixedly mounted on described crossbeam 2, and thus, truck transom is used for bearing motor, gear case, brake system quality, and bears cross-car applied loading.
The present embodiment is designed to example with framework structure, reaches expendable weight, reduces the object of noise.
