Description
Technical field
This utility model relates to a kind of connecting device, the specifically connecting device between a kind of railcar body and bogie.
Background technology
In existing railway rail car, it is generally adopted the connected mode of parallel draw bar between car body with bogie to transmit traction force, brake force. But parallel draw bar structure is more complicated, parts are more, maintaining is inconvenient in assembling. Each connection joint of parallel draw bar and rod member all adopt hard parts, make car body and bogie longitudinally for being rigidly connected, longitudinal impulse and vibration is produced in starting in railcar, brake and running, make car body all bear bigger impact of collision load with the rod member of the connection seat of bogie, parallel draw bar, and cause the wheel rail adhesion state of driving wheel to a certain extent.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of railway trackage car connecting device, namely adopts the connected mode of single stayed pole between car body and bogie; This device have simple and reliable for structure, exempt from abrasion, it is easy to safeguard, the feature of complete function. The two ends of its stayed pole are provided with caoutchouc elasticity node, have both ensured to have sufficiently longitudinally tractive rigidity, reduce again horizontal and vertical additional stiffness, effectively improve the longitudinally connected performance of bogie.
The technical solution of the utility model is: a kind of railcar connecting device, including car body, tractive shank, bogie, bogie crossbeam, stayed pole, tractive pole socket, pressing plate, bolt, lock washer, the longitudinally connected beam of bogie, rubber backstop, stopping seat, nut.
Described railcar connecting device: tractive shank is arranged on car body with the first bolt and heavy spring washer; The U-shaped mandrel of one end of stayed pole is installed in the U-lag of tractive shank, stayed pole and tractive shank is locked together by the second pressing plate, the 3rd bolt and the second lock washer; The U-shaped mandrel of the stayed pole other end is installed in the U-lag of tractive pole socket, tractive pull bar and tractive pole socket is locked together by the first pressing plate, the second bolt and the first lock washer; Tractive pole socket is welded on the crossbeam of bogie; On the longitudinally connected beam of bogie of the tractive shank left and right sides, it is respectively welded the stopping seat that structure is identical, is fixed on stopping seat with the 4th screw bolt and nut by transversely mounted for identical for structure rubber backstop; Rubber backstop is set to circular tower shape or cylinder, and the cylindrical of circular tower shape or cylindrical rubber backstop is provided with groove; Adjusting pad is assemblied between circular tower shape rubber backstop and stopping seat, and adjusting pad is used for the gap adjusting between circular tower shape rubber backstop and tractive shank.
This utility model by adopting the connected mode of single stayed pole between car body and bogie, and its caoutchouc elasticity node has buffering extensional vibration and consumes the effect of vibrational energy, can effectively improve the longitudinal dynamics performance of railcar.

Detailed description of the invention
In Fig. 1, Fig. 2 embodiment that this utility model provides: with the first bolt 3 and heavy spring washer 4, tractive shank 2 is arranged on car body 1; The V-type mandrel of one end of stayed pole 11 is installed in the U-lag of tractive shank 2, stayed pole 11 and tractive shank 2 is locked together by the second pressing plate the 12, the 3rd bolt 13 and the second lock washer 14; The U-shaped mandrel of stayed pole 11 other end is installed in the U-lag of tractive pole socket 7, stayed pole 11 and tractive pole socket 7 is locked together by first pressing plate the 8, second bolt 9 and the first lock washer 10, and tractive pole socket 7 is welded on the crossbeam 6 of bogie. The horizontal backstop 16 being made up of stopping seat 17, rubber backstop the 19, the 4th bolt 21 and nut 18 is arranged on the longitudinally connected beam 15 of bogie of tractive shank 2 left and right sides.
Pull strength, brake force on bogie 5 are ultimately transferred to car body 1 by path as follows:
Bogie 5 �� bogie crossbeam 6 �� tractive pole socket 7 �� stayed pole, 11 �� tractive shank 2 �� car body 1.
In the embodiments of figure 3: on the longitudinally connected beam 15 of bogie in tractive shank 2 left and right sides, be respectively welded the identical stopping seat of structure 17, it is fixed on stopping seat 17 with the 4th bolt 21 and nut 18 by transversely mounted for identical for structure rubber backstop 19; Rubber backstop 19 is set to circular tower shape or cylinder, and the cylindrical of circular tower shape or cylindrical rubber backstop 19 is provided with groove 22; Adjusting pad 20 is assemblied between circular tower shape rubber backstop 19 and stopping seat 17, and adjusting pad 20 is used for the gap adjusting between circular tower shape rubber backstop 19 and tractive shank 2, it is prevented that tractive shank 2 has excessive lateral displacement relative to bogie 5.
