Abstract
The utility model discloses a linear motor bogie which is improved according to the foundation structure of a framework, improves the rigidity and strength of the framework based on an X-shaped integral structure, decreases the torque influence on the framework caused by weight of a vehicle when the bogie is in a high-speed overlarge angle curve, and improves the safety coefficient of the vehicle in high-speed driving. The bogie consists of two groups of wheel pairs, a wheel axle connecting each group of wheel pairs, and an axle box body and a supporting box body that are sheathed at the axle journal of the wheel axle by bearings, wherein the framework is installed on the axle box body in a bearing manner, a linear motor is suspended on a transverse suspension beam by a vertical suspender, and two ends of the transverse suspension beam are arranged on the supporting box body by elastic joints. The framework consists of side beams, cross beams and end beams that are welded and assembled, and the two side beams are oppositely and inwards bent to form the X-shaped integral structure. The X-shaped integral structure can effectively the rigidity and strength of the framework, further decrease the torque influence on the framework when the bogie is in the high-speed overlarge angle curve, and provide more reliable safty guarantee for the high-speed driving of the bogie.
Description
Technical field
The utility model relates to a kind of linear electric motors bogie truck that is applied to guideway vehicle, belongs to mechanical manufacturing field.
Background technology
Follow the fast development of domestic city track traffic, the linear electric motors bogie truck to guidance capability, is obtained the approval in overall technology leading superiority and market with the wheel of its less oad and weight, bigger outside installing space and optimization just step by step.
In the existing technical scheme that adopts, linear electric motors are installed on the supporting box below at axle journal place by a pair of lateral suspension beam.For guaranteeing that the lateral suspension beam can carry out limited axis rotation around its attachment point,, normally take rubber nodal point that the lateral suspension beam flexibly is carried on supporting box with of the small size swing of reply vehicle ' process cathetus motor with respect to bogie truck.
For this type of linear electric motors bogie truck, stability when improving moving velocity further and crossing curve, need reduce the weight of framework and single stage suspension system as much as possible, but also must guarantee framework whole rigidity and intensity simultaneously, the torque influence of bringing with reply bogie truck and car body relative position when crossing the wide-angle curve.
The unsprung weight of single stage suspension system is bigger, is unfavorable for reducing the wear ability of wheel, correspondingly brings the adjustment problem of linear electric motors suspension height.
In addition, the existing external brake disc structure that adopts, can be when crossing bent angle at a high speed two side wheels between form " shoulder pole " effect, need to improve the wheel counter stress situation at every group of axletree two ends.
In view of this, the special present patent application that proposes.
The utility model content
Linear electric motors bogie truck described in the utility model, its design goal is to solve the problem of above-mentioned prior art existence and is improved at the framework basic design, integral structure by the X type is to improve the rigidity and the intensity of framework, framework is subjected to the torque influence that weight produces on the car, the safety factor when improving high vehicle speeds when improving bogie truck and crossing the wide-angle curve at a high speed.
Another design goal is to optimize and reduce the unsprung weight of single stage suspension system, the wheel abrasion resistance in being beneficial to run at high speed.
Design goal also is, improve the car brakeing structure, reduce two side wheels between " shoulder pole " effect.
For realizing above-mentioned design goal, described linear electric motors bogie truck mainly includes:
2 groups of wheels are right, connect every group of axletree that wheel is right,
Be located at journal box body, the supporting box at axle journal place by bearing carrier ring,
The framework carrying is installed on journal box body,
Linear electric motors hang on the lateral suspension beam by vertical suspension rod, and the two ends of lateral suspension beam are installed on supporting box by elastic panel nodes.
The difference with the prior art part is that described framework is made up of curb girder, crossbeam and the end carriage of welding assembly, and two curb girders bend to the inside opposite to each other and form the integral structure of X type.
As above-mentioned basic scheme feature, X type integral structure can improve the rigidity and the intensity of framework effectively, and then optimizes the torque influence that is subjected to when bogie truck is crossed the wide-angle curve at a high speed, and running at high speed for bogie truck provides more failure-free safety control.
For reducing the unsprung weight of single stage suspension system effectively, the additional prioritization scheme that can take is, described curb girder integral body is the box welded structure of hollow, and crossbeam is hollow solid drawn pipe, and the two ends of crossbeam are run through the curb girder of both sides respectively and are welded to connect with it.
Said structure improves and to be based on framework weight-saving mentality of designing, but adopts the also auxiliary chamber of double as air bellow of crossbeam that solid drawn pipe makes.
For tackle wheel that existing employing EN standard makes to reduce unsprung weight further, described axletree has elongated hollow structure, and the board-like disc brake of straight-arm is installed below end carriage.
By reducing unsprung weight and adopting the board-like brake structure of straight-arm, can strengthen the right abrasion resistance of wheel, and then improve the adjustment of wheel rail relation, minimizing linear electric motors suspension height.
As mentioned above, the advantage and the beneficial effect that have of the utility model linear electric motors bogie truck is:
1, improve the rigidity and the intensity of framework with the integral structure of X type, framework was subjected to the torque influence that weight produces on the car when optimizing and improving at a high speed the wide-angle curve significantly, and the safety factor of high vehicle speeds is higher.
2, optimize and reduce the unsprung weight of single stage suspension system, the wheel abrasion resistance in being beneficial to run at high speed.
3, improve the car brakeing structure, reduce two side wheels between " shoulder pole " effect.
Description of drawings
Now in conjunction with the following drawings the utility model is described further
Fig. 1 is the scheme drawing of described linear electric motors bogie truck;
As shown in Figure 1, framework 1 is taken turns to 2 air bellow 3, central draw gear 4, lateral suspension beam 5, the board-like disc brake 6 of straight-arm, pantagraph current collector 7, linear electric motors 8, electrical control pipeline 9, axletree 10, journal box body 11, supporting box 12, vertical suspension rod 13, curb girder 14, crossbeam 15, end carriage 16.
