Abstract
Stabilizing device for compensating by restraining the relative rocking movements between an articulated railroad car body and bogie running at high speed. The device comprises, longitudinally extending across the frame of the bogie a tube having sufficient stiffness for being free of any torsion, adapted to rotate inside bearings disposed at the extremities of the frame. The tube is provided at its extremities, with two parallel crank-arms integrally connected to the tube. The extremity of each of the crank-arms is articulated to a rigid connecting member which is attached on the other hand, by means of a swivel-joint, to a corresponding car body.
Claims8
A device for compensating for the rocking movements between a railroad bogie and articulated railroad car bodies, the ends of which are supported on the bogie, the device comprising:
- a. a bogie having a frame;
- b. a torsionally rigid, elongated member pivotally supported in said bogie by bearings;
- c. first and second crank arms, one end of each crank arm being rigidly and integrally fixed to said elongated member;
- d. first rigid means, coupled to the other end of said first crank arm, for rigidly connecting said first crank arm to one car body;
- e. second rigid means, coupled to the other end of said second crank arm, for rigidly connecting said second crank arm to another car body;
- f. means for selectively releasing said first and second rigid connecting means to allow generally free relative movement between the car bodies and bogie so that said first and second rigid connecting means may be released at lower speeds to facilitate negotiation of relatively tortuous track;
- g. whereby the car bodies may be selectively coupled together at high speeds to restrain their freedom of movement with respect to each other and with respect to the bogie thereby compensating for the usual rocking movements between the bogie and the car bodies.
