Abstract
The utility model discloses a rail train bogie is with pulling rod node, including dabber, overcoat, first rubber layer, second rubber layer and inserted sheet, the both sides on first rubber layer all with the overcoat is fixed to be linked to each other, the shaping after the first rubber layer vulcanization of dabber left and right sides is passed through with the overcoat to the dabber, the dabber with be equipped with between the overcoat about two clearance holes of dabber symmetry, be equipped with inserted sheet and second rubber layer in the clearance hole, dabber, second rubber layer, inserted sheet connect gradually, the shaping after the second rubber layer vulcanization on inserted sheet and dabber pass through both sides about the dabber, the inserted sheet all does not contact with first rubber layer, overcoat. The middle height of inserted sheet, both sides are low, and the cross-section is trapezoidal area that has reduced with the overcoat contact, has also played the damping and has reduced the effect of wearing and tearing, and the inserted sheet contacts with the overcoat during operation, and the dabber is transmitted again to the inserted sheet and the collision of overcoat through behind the rubber, has avoided the easy problem of wearing and tearing of rubber and overcoat contact.
Description
Technical Field
The utility model relates to a rail train accessory field particularly, relates to a rail train bogie is with pull rod node.
Background
The traction pull rod nodes are arranged at two ends of a traction pull rod of the bogie, one end of the traction pull rod node is connected with the bogie body, and the other end of the traction pull rod node is fixed on the bogie and mainly bears the longitudinal force for transmitting traction or braking, so that the stable operation of the train is ensured. If the rigidity of the product is too high, the damping and buffering effects are influenced, and the comfort of passengers is influenced. If the rigidity of the product is too low, the service life of the product is affected. Therefore, in order to meet the running requirements of the train, the rigidity of the traction pull rod node needs to be changed and matched with the traction pull rod node, and the structural change is caused by the rigidity change. The traction pull rod node structure is provided with holes so as to achieve corresponding rigidity, but the traction pull rod node with the holes at present has the problems of large vibration, serious abrasion and the like, and therefore, the traction pull rod node with a novel structure needs to be developed to solve the problems.
An effective solution to the problems in the related art has not been proposed yet.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a rail train is traction rod node for bogie to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a rail train bogie is with pulling rod node, includes dabber, overcoat, first rubber layer, second rubber layer and inserted sheet, the both sides on first rubber layer all with the overcoat is fixed continuous, the dabber vulcanizes the back shaping with the first rubber layer that the overcoat passes through the dabber left and right sides, the dabber with be equipped with between the overcoat about two clearance holes of dabber centrosymmetry, be equipped with inserted sheet and second rubber layer in the clearance hole, dabber, second rubber layer, inserted sheet connect gradually, the shaping is vulcanized on the second rubber layer on inserted sheet and dabber about through the dabber both sides, the inserted sheet with first rubber layer, overcoat all contactless.
Furthermore, the middle of the inserting piece is high, the two sides of the inserting piece are low, and the cross section of the inserting piece is trapezoidal.
Furthermore, two ends of the inserting piece protrude to the outer sides of two ends of the outer sleeve, and the protruding length is between one fourth and one half of the radius of the inner ring of the outer sleeve.
Furthermore, the two ends of the second rubber layer protrude to the outer sides of the two ends of the outer sleeve, and the protruding length is equal to the length of the inserting piece protruding to the outer sleeve.
Compared with the prior art, the utility model discloses following beneficial effect has:
(1) the insertion piece is added at the position of the clearance hole of the node of the traction pull rod, the insertion piece is contacted with the outer sleeve during operation, the problem that the rubber is easily abraded when being contacted with the outer sleeve is avoided, the insertion piece collides with the outer sleeve during operation, and the rubber is transmitted to the mandrel, so that a good vibration damping effect is achieved;
(2) the middle of the inserting piece is high, the two sides of the inserting piece are low, the inserting piece is of a trapezoidal structure, the contact area of the inserting piece and the outer sleeve is reduced, and the effects of vibration reduction and abrasion reduction are achieved.
