Accomplish that the two kinds of bogie of car is the most general, manufacturing cost can be saved.
Forced guiding mechanism of the present utility model can make bogie front and rear wheel more they tend to than self steering bogie the when of by curve
Radial position, increases the utilization of adhesion on curve, reduces wheel-rail wear and tear simultaneously.
Compared with existing forced steering bogie, owing to the wheelbase between this structure with bogie axle is unrelated, do not interfere with
The installation of traction electric machine, is especially suitable for high-power locomotive and uses.
Analyzing through SIMPACK dynamics software, this utility model reduces 20% to the abrasion of wheel track than self steering bogie,
Improve bogie curving performance and lateral stability simultaneously.
Verify through SIMPACK dynamics software, car load of the present utility model abrasion power HTCR to be less than radial steering.
