Abstract
The invention discloses a traction nodding control device used for linking a straddle type single-rail single-shaft bogie with a vehicle body. The device is arranged on the straddle type single-rail single-shaft bogie and used for controlling nodding movement of a straddle type single-rail single-shaft vehicle in the traction and braking processes and transmitting the longitudinal force between the vehicle body and the bogie. The device comprises two pairs of traction rod mechanisms which are of the same structure and arranged at the two sides of a track beam (17) in a relatively-parallel mode respectively. The traction nodding control device is installed below the operation plane of traveling wheels, the floor height is lowered, and the passenger capacity is increased. A first step of each torsion bar is an external spline, an internal spline is formed in each linkage component, and through cooperative application of the splines, it is guaranteed that the large torque is transmitted under the circumstance that the diameters of the torsion bars are small. A second step of each torsion bar is in cylinder axis clearance fit with a corresponding frame foundation, the frame foundations rotate within a certain horizontal range relative to the torsion bars, and the frame foundations are linked with arms extending from the lower end of the vehicle body, so that it is guaranteed that when the vehicle negotiates a curve, the vehicle body does not rotate with rotation of the bogie, and thereby the vehicle negotiates the curve smoothly.
