As shown in Figure 1, in above-described embodiment, all arrange a mechanical skid device each wheel to axletree 201 one end of assembly 20, mechanical skid device belongs to annex 70.

Principle of work of the present invention is:

The transmission of vertical force and vibration damping: if power is from get on the bus (vertical load, mainly car body deadweight, load-carrying and live load), its transfer route is: first, vertical force reaches on the curb girder 101 of framework assembly 10 by the band wearing plate side bearing 501 in secondary suspension device 50 and band roller side bearing 502, is with wearing plate side bearing 501 and band roller side bearing 502 to provide certain vertical damping simultaneously; Secondly, vertical force passes on pivoted arm 302 by the coil spring assembly 301 of single stage suspension device 30, and one is that vertical damper 306 provides Vertical Vibration Reduction; Then, vertical load to be passed to wheel on the axletree 201 of assembly 20, wheel 203 by pivoted arm 302 by pivoted arm saddle face 303, antifriction-bearing box 202 by vertical force, finally reaches transmission and vibration damping that rail realizes vertical load; If power is come to track, the transmission of its power is contrary with to getting on the bus.

The transmission of transverse force and vibration damping: the application force of transverse force mainly owing to producing with vehicle structure feature under specific circuit condition of service.Its transfer route is: first, the band wearing plate side bearing 501 of side-friction in secondary suspension device 50 is uploaded on the curb girder 101 of framework assembly 10 with band roller side bearing 502, other transverse forces then reach on traction Connection Block 405 through the centre of pull pin 402 of draw gear 40, towing pin node 404, deflection again through drawing pull bar 406, rubber nodal point and drawing pull bar mount pad 104 reaches on truck transom 102, and wherein two is that lateral damper 503 provides lateral vibration absorbing; Secondly, allly act on the pivoted arm that the transverse force on framework assembly 10 passes to pivoted arm 302 through the lateral stiffness of coil spring assembly 301 and pivoted arm node 305 axial stiffness and deflection stiffness and carry on horizontal platform 304, utilize the transverse shear deformation of the rubber damping pad 308 in coil spring assembly 301 to provide certain vibration damping on the one hand, utilize the axis of pivoted arm node 305 and deflection stiffness to provide lateral vibration absorbing simultaneously; Then, act on transverse force on pivoted arm 302 and carried the friction in horizontal platform 304 and pivoted arm saddle face 303 by pivoted arm, transverse force is reached on antifriction-bearing box 202, axletree 201, wheel 203 and finally reach rail, realize transmission and the vibration damping of transverse load; If power is come to track, the transmission of its power is contrary with to getting on the bus.

The transmission of longitudinal force and vibration damping: longitudinal force mainly divides tractive force and braking force, effect route is contrary.Wherein the transfer route of tractive force is substantially identical with transverse force before reaching single stage suspension device 30, and difference is that the direction of power is for longitudinal; But the longitudinal force transmission between framework assembly 10 and single stage suspension device 30 is then: act on longitudinal force on curb girder 101 through pivoted arm node 305, utilize the large longitudinal register rigidity of node to transmit longitudinal force on pivoted arm 302 and longitudinal pivoted arm saddle face 303, then reach on rail level through antifriction-bearing box 202, axletree 201, wheel 203; Braking force be then clamp that brake disc 204 produces that friction brake force makes axletree 201 by brake clamp 603, wheel 203 reverses and produces binding force with rail and realize braking, the adhesion braking power produced is delivered to pivoted arm 302 through axletree 201 and antifriction-bearing box 202, reaches on framework assembly 10 through pivoted arm node 305, reach the traction Connection Block 405 in draw gear 40 again through drawing pull bar 406, reach on centre of pull pin 402 through towing pin node 404.

The various embodiments described above are only for illustration of the present invention, and wherein the structure, connection mode etc. of each parts all can change to some extent, and every equivalents of carrying out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
