Independent wheel is to hanging the linear electric motors bogie truck
Technical field
The utility model relates to a kind of bogie truck that is used for guideway vehicle, and the right vehicle bridge of independent specifically wheel is hung linear electric motors, belongs to mechanical manufacturing field.
Background technology
Be applied to the bogie truck of railroad train, subway and light rail transit vehicle, the existing rigid frame structure that generally adopts.Wheel is hung linear electric motors to being provided with journal box body realize to install, and one is that the quality of spring lower part is bigger in this class formation, and wheel is higher to the influence that is subjected to the below track and impacts.And the air gap mobility scale between linear electric motors and the tablet is bigger, thereby under the certain prerequisite of output tractive force, the energy consumption of linear electric motors is also just higher.
The utility model content
The purpose of this utility model is to provide a kind of independent wheel to hanging the linear electric motors bogie truck, to address the above problem and defective.Adopt independent wheel to structure, and incite somebody to action independence by bearing and take turns being fixed on the two ends of vehicle bridge, linear electric motors are hung the sidepiece of vehicle bridge by suspension rod, reduce unsprung weight by cancellation journal box body this structure, thus reach reduce wheel to the influence that is subjected to track and impacts and reduce linear electric motors and tablet between the air gap mobility scale, improve energy utilization rate.
For realizing above-mentioned design goal, described independent wheel mainly has following structure to hanging the linear electric motors bogie truck:
Include framework and forward and backward independent wheel is right, wherein,
Independent wheel is to being connected the two ends of vehicle bridge by bearing fixing, linear electric motors are hung the sidepiece of vehicle bridge by vertical suspension rod, and vehicle bridge is that the longitudinal traction pull bar connects framework by one, and linear electric motors connect framework by longitudinal tie, lateral connecting rod respectively.
As above-mentioned scheme feature, the independent wheel that is adopted need not the installation shaft casing, and linear electric motors are hung and directly born from the ground-surface track irregularity and encourage by suspension rod.
Compare with in the prior art linear electric motors being suspended on the journal box body, the utility model has been cancelled the journal box body structure, thereby has reduced unsprung weight effectively, and wheel reduces the influence that impacted by track, and the air gap between linear electric motors and the tablet is minimized.
Hang the performance of linear electric motors and regulate vertical coupling stiffness for improving vehicle bridge, described vehicle bridge has the crane span structure of middle epirelief, the sidepiece of vehicle bridge is provided with the mount pad of hanging that is used to hang linear electric motors, and vertical suspension rod is installed to by ball joint bearing and height adjustment nut and hangs mount pad.
For improving vertical effectiveness in vibration suppression, one is that vertical rubber piles up spring and is directly installed on the vehicle bridge.
For guaranteeing the air gap mobility scale between linear electric motors and the tablet, in the plane of oscillation that the basic controlling sling point constitutes, adopt 3 vertical suspension rods to hang linear electric motors, hang mount pad and be separately positioned on the opposite planar of forward and backward vehicle bridge inboard.
As above content, described independent wheel to the advantage that suspension linear electric motors bogie truck has is, adopt independent wheel to the sidepiece of linear electric motors being hung in vehicle bridge, cancelled this structure of journal box body to reduce unsprung weight, the influence that is subjected to the track impact, air gap mobility scale, the raising linear electric motors power that reduces between linear electric motors and the tablet have been exported thereby can reduce wheel effectively.
Description of drawings
Now with explanation the utility model is done further explanation in conjunction with the following drawings.
Fig. 1 is that wheel is to being installed to the structural representation of vehicle bridge;
Fig. 2 is that linear electric motors are hung scheme drawing;
Fig. 3 is described bogie structure scheme drawing;
Fig. 4 is the schematic top plan view of Fig. 3.
As shown in Figures 1 to 4, framework 1 is taken turns 2, linear electric motors 3, and vehicle bridge 4, crane span structure 41 is hung mount pad 42;
One be vertical rubber to pile up spring 6, be longitudinal traction pull bar 7, tablet 8, vertical suspension rod 9, longitudinal tie 10, lateral connecting rod 11 and height adjustment nut 12.
The specific embodiment
Embodiment 1, and as shown in Figures 1 to 4, described independent wheel includes framework 1 to hanging the linear electric motors bogie truck, and forward and backward independent wheel is to 2.Wherein,
Independent wheel is to 2 two ends that are connected vehicle bridge 4 respectively by bearing fixing, and linear electric motors 3 are hung vehicle bridge 4 opposed inside portions by 3 vertical suspension rods 9.
Vehicle bridge 4 has the crane span structure 41 of middle epirelief, the inside portion of vehicle bridge 4 be provided be used to hang linear electric motors 3 hang mount pad 42, each vertical suspension rod 9 all is installed to by ball joint bearing and height adjustment nut 12 and hangs mount pad 42.One is that vertical rubber piles up the bridge that spring 6 is directly installed on vehicle bridge 4 and adds 41 both sides.
Vehicle bridge 4 is that longitudinal traction pull bar 7 connects framework 1 by one, and linear electric motors 3 connect framework 3 by longitudinal tie 10, lateral connecting rod 11 respectively.
