Abstract
The utility provides a primary resilient positioning device for a railway vehicle, which is in a composite structure that a shaft box is adopted to resiliently position and combine a primary vertical stopper, so as to optimize positioning stiffness of the axle box and ensure a bogie to have a high critical instability velocity. A resilient buffer stopper is additionally arranged in a primary vertical spring device, so as to avoid forming greater rigid impact at positions such as a wheel pair, the axle box and the like when the primary vertical load is too big or a primary vibration damping part is in failure. The primary resilient positioning device is arranged between the framework of the bogie and the vertical direction of a wheel axle, and comprises a rotating arm type axle box body and a primary spring device arranged at the top end of the axle box body. One end of the axle box body is installed on the framework through a rubber elastic joint, and the other end of the axle box body is connected with the framework through a vertical vibration absorber. The primary resilient device is provided with an upper plywood and a lower plywood as well as a twin-twisted spiral spring tightly pressed and mounted between the upper plywood and the lower plywood. The inner ring of the twin-twisted spiral spring and the bottom part of the upper plywood are connected with a rubber stopper through an integral vulcanization process.
Description
Technical field
The utility model is that to be applied to one of rail vehicle truck be elastic positioning device, belongs to mechanical manufacturing field.
Background technology
Along with improving constantly of domestic city rail traffic vehicles running velocity, the continuous increase of operation density, for how to guarantee that the rail traffic vehicles bogie truck continues, safety, smooth running proposed higher designing requirement.In the single stage suspension system of current operation bogie truck, framework and wheel between mostly adopt the rubber laminated spring as main vibration insulating system, by set certain one by one tying retaining gap width play final supporting role at spring failure.For avoiding one is to the rigid shock of wheel track when losing efficacy, or slow down the negative interaction that this impact brings, the tying retaining buffer structure that employing has the elasticity positioning function is very tangible to the effect that damping cushion effect and journal box body connective stability are provided, as taking elastic positioning device and be aided with the axle box vertical damper between journal box body and framework.
The single stage suspension system of existing urban rail transit vehicles, one is spring installation surge guard effect to axle box when not possessing the excessive or damping means of vertical load and losing efficacy, and therefore can't alleviate at the rigid shock of wheel to positions such as, axle boxes.
In addition, also being unrealized in the technology at present and having effective isolation concurrently is the characteristics that locating stiffness is selected flexibly from the low-frequency vibration and of track, the axle box locating stiffness awaits further optimization, and the high critical unstability speed of bogie truck is failed to solve and caused curve negotiation ability lower.
The utility model content
Urban rail transit vehicles one described in the utility model is an elastic positioning device, it is the composite structured of vertical backstop that its design goal is to solve the problem of above-mentioned prior art existence and take axle box elasticity positioning combination one, to optimize the axle box locating stiffness and to guarantee that bogie truck has high critical unstability speed.
Design goal of the present utility model is, is to increase elastic buffer backstop in the vertical spring installation one, is that vertical load is when excessive or one be that damping means formed bigger rigid shock at wheel to positions such as, axle boxes when losing efficacy to avoid one.
Another design goal is, one is that pivoted arm rubber nodal point locate mode is adopted in the location, realizing guideway vehicle vertically, laterally and the flexible positioning on the hand of rotation, thereby improves the curve negotiation ability under the bogie truck higher critical velocity state.
For realizing above-mentioned design goal, described guideway vehicle one is that elastic positioning device is arranged on truck frame and wheel between vertical, mainly includes:
Pivoted arm journal box body and to be arranged at one of journal box body top be spring installation.
The difference with the prior art part is that an end of journal box body is installed on framework by the caoutchouc elasticity node, and its other end is connected with framework by a vertical damper.
Described one is spring installation, has train wheel bridge and lower plate, and the two volume coil springs that compress installation between train wheel bridge and lower plate.
In two volume coil springs,, and realize elastic buffer structure between the lower plate by elastic caoutchouc backstop to train wheel bridge bottom employing overall sulfur metallization processes connection one.
As above-mentioned basic scheme, adopt the locate mode of pivoted arm journal box body, its caoutchouc elasticity node that is installed on framework can realize whole bogie truck vertically, laterally, flexible positioning on the hand of rotation, help one be locating stiffness on vertical, vertical and horizontal, be optimized selection independently.
And this type of journal box body connects the optimal design of locate mode, can also guarantee that bogie truck has high critical unstability speed and good curve negotiation ability.
Increase two volume coil springs that rubber backstop is arranged, except that the low-frequency vibration that can isolate effectively from track, can by rubber integral body vulcanize in train wheel bridge and effectively guard sheaver, journal box body is not subjected to the rigid shock of framework.
For further improving wheel, journal box body is subjected to the protective action of rigid shock and increases the wear-resisting effect of rubber backstop, can connect the anti-protection pad of a nylon in rubber backstop bottom.
As mentioned above, the utility model urban rail transit vehicles one is that elastic positioning device has following advantage:
1, can avoid one to be that vertical load is excessive or one be that damping means formed bigger rigid shock at wheel to positions such as, axle boxes when losing efficacy effectively.
2, one is that elastic positioning device has been realized the alerting ability of guideway vehicle on vertical, horizontal and hand of rotation, has guaranteed the curve negotiation ability under the bogie truck higher critical velocity state.
3, integral structure can be isolated the low-frequency vibration from track effectively, and helping one is the optimized choice of locating stiffness
