Abstract
The utility model relates to a truck secondary suspension device, which adopts a combined structure of a low-rigid non-liner air spring, a large-gap high-rigid transverse stop and a side rolling prevention torsion rod device to ensure running safety performance, increase vehicle dynamic performance, and integrally increase safety parameters of vehicle high-speed running. The truck secondary suspension device mainly comprises a pair of air springs installed between a vehicle body and a truck frame and arranged transversely; and a pair of transverse stops is installed on the inner side of the truck frame. Compared with the prior art, the truck secondary suspension device is characterized in that inside the air springs, a gap between a block limiting transversely move of the vehicle body and a cavity ranges from 8 millimeters to 15 millimeters; the side rolling prevention torsion rod device is installed between the vehicle body and the truck frame; two ends of a transverse torsion rod are respectively installed on a side mounting seat of the frame through sliding bearings; and a truck is connected with the vehicle body through two torsion arms installed on the transverse torsion rod and two connection rods installed on a vehicle body mounting seat to realize side rolling prevention function.
Description
Technical field
The utility model is at the improvement of rail vehicle truck secondary suspension device, belongs to mechanical manufacturing field.
Background technology
The speed per hour of present domestic motor train unit has reached 350 kilometers/hour, along with the significantly speed-raising of guideway vehicle, has higher requirement at bogie truck and car body safe operation and travelling comfort design.
The secondary suspension device of carrying truck frame and car body, the use fully under the high-speed cruising state seems particularly important for car body, has following difficult point in adaptation vehicle high-speed cruising and dynamic performance design always.
The air bellow that how to adopt rigidity, is complementary with lineament? guideway vehicle produces lower vertical, lateral stiffness and reaches corresponding comfort level with assurance when linear portion moves.But through too small curve bend the time,, therefore require air bellow that big lateral stiffness is provided immediately for the restriction car body produces big cross travel.
As if the vertical stiffness that obviously reduces air bellow, then must consider and solve anti-problem of sidewindering simultaneously, thus the performance that raising process small bend angle track or anti-strong wind topple.
In addition, during high-speed cruising, providing the stop mechanism of lateral stiffness easily to clash into car body on little curve, is also necessary this type of problem of solution of vehicle high-speed cruising safety that guarantees under the unusual service condition.
The utility model content
Bogie truck secondary suspension device described in the utility model, its design goal is to address the above problem and takes the low non-linear air bellow of rigidity, the horizontal backstop of the high rigidity in big gap and the unitized construction of torsion bar mechanism for preventing side rolling of train carriage, to guarantee operational safety performance and to improve the vehicle dynamics performance, integrally improve the safety factor of car body high-speed cruising.
For realizing above-mentioned design goal, described bogie truck secondary suspension device mainly includes:
Be installed between car body and the truck frame, along a pair of air bellow of horizontally set;
At a pair of horizontal stop of truck frame installed inside.The difference with the prior art part is,
In air bellow inside, the block and the gap between the cavity of the displacement of restriction cross-car are the 8-15 millimeter.
As above-mentioned basic scheme, adopt the nonlinear air bellow of this type of low rigidity that vertical less rigidity, horizontal bigger nonlinear characteristic can be provided.
When vehicle high-speed cruising during at linear portion, air bellow produces lower lateral stiffness so that comparatively significantly ride quality to be provided.
And when high-speed cruising was on little curve, the lateral stiffness of air bellow increased suddenly with restriction car body generation cross travel.
Hang low to the anti-problem of sidewindering of rigidity car body for improving, a torsion bar mechanism for preventing side rolling of train carriage can be installed between car body and truck frame.
Type and the structure of existing torsion bar mechanism for preventing side rolling of train carriage are more, and the utility model provides the comparatively torsion bar mechanism for preventing side rolling of train carriage of compactness of following comparatively preferred, mounting structure.Particularly,
The two ends of one transverse torque rod are installed on framework side mount pad by plain bearing respectively, are connected a pair of vertical connecting rod between framework side mount pad and the car body side mount pad.
Above-mentioned torsion bar mechanism for preventing side rolling of train carriage can be suitable for and be matched with the air bellow that hangs low to rigidity, can install and provide the anti-performance of sidewindering in less space.
Further the refinement improvement project is that the gap between described horizontal stop and the center pin is between the 30-50 millimeter.
Under the prerequisite that adopts above-mentioned low cross rigidity, non-linear air bellow, the horizontal backstop by big gap, high rigidity can reduce the bump with car body, increases the vehicle safety performance under the unusual service condition.
As mentioned above, the utility model bogie truck secondary suspension device has the following advantages:
Realize the project organization that air spring rigidity and lineament are complementary, take into account safety of vehicle high-speed cruising and ride quality;
Solve the anti-problem of sidewindering under the vertical less rigidity prerequisite effectively, avoid being subjected to wind effect and the possibility of toppling through small bend angle track or car body;
The bump of stop mechanism and car body in the time of can avoiding on little curve high-speed cruising guarantees the vehicle operating safety under the unusual service condition.
