It is for constraint that framework is shaken the head that two hinge-points of left side front-wheel pull bar, left side trailing wheel pull bar and left side beam stagger in vertical direction each other, prevents yaw motion; It is for framework is sidewindered to constraint that two hinge-points lay respectively at a side separately in the horizontal direction, prevents to sidewinder motion, and such structure can realize the release of horizontal degree of freedom again simultaneously, is exactly to discharge the horizontal centnifugal force of framework in other words.
Connection structure between right side front wheel pull bar, right side rear wheel pull bar and pivoted arm has realized the right coupling of shaking the head of front and back wheel, and while making bogie truck cross curve, two-wheeled is to Shaft angle opposite direction, and size is identical; The articulated structure of left side front-wheel pull bar, left side trailing wheel pull bar and left side beam has weakened framework to taking turns right position constraint, and realize front and back wheel increases the degree of freedom that traverses to each.
Working process and principle are as follows: adopt the rolling stock of this radial steering when crossing curve, due to the impact of creep moment, front-wheel is to rotating along curve, and wheel is to orientation of its axis center of curve.Front-wheel rotates the right side front wheel pull bar that can drive right side beam one side to axle, right side front wheel pull bar drives pivoted arm rotation, pivoted arm is torn right side rear wheel pull bar, right side rear wheel pull bar forces trailing wheel the hinge-point between axle to be rotated around right side rear wheel pull bar and trailing wheel axle, trailing wheel points to center of curve to axle, and front and back wheel to forming desirable "eight" shape when crossing curve.The front and rear wheel of left side beam one side can relatively take turns to there being certain traversing amount framework to the articulated structure of axle and framework when crossing curve simultaneously, prevents from retraining excessive.
Further limit, it is hinged that left side front-wheel pull bar, left side trailing wheel pull bar, right side front wheel pull bar, right side rear wheel pull bar and front and rear wheel cut with scissors joint to the end of axle by elasticity, and it is hinged that left side front-wheel pull bar, left side trailing wheel pull bar and left side beam cut with scissors joint by elasticity.Elasticity hinge joint is because its elastic material becomes hinge joint to a certain degree displacement is provided such as rubber can produce shape, and due to the excitation of track irregularity, the contact-impact between mechanical joint can be avoided in elasticity hinge joint, causes fatigue damage.
Particularly, front-wheel all has axle box to axle, trailing wheel to four of axle ends, and left side front-wheel pull bar, left side trailing wheel pull bar, right side front wheel pull bar, right side rear wheel pull bar are hinged on respectively front and rear wheel on four of the end of axle axle boxes.
The invention has the beneficial effects as follows: this bogie truck leverage used is less, being arranged on wheel counter-lateral quadrents can not affect locomotive drive system, for convenience detach and install, and has all preceences of mono-pendulum type Self-Steering Power Bogie; Utilize simultaneously front and rear wheel to axle one end by rod hinge connection on framework, two degree of freedom that traverse have been increased, can make full use of creep moment, realize between front and back wheel pair and framework, shake the head direction and horizontal decoupling zero, solved framework in mono-pendulum type bogie truck, with wheel, cross travel has been retrained to excessive problem, larger to the lifting meaning of radial steering space availability ratio.
