| description | PURPOSE:To provide a mechanism for forcibly inclining a car body with a simple constitution for improving on-curve passing speed by interconnecting left and right pneumatic springs supporting a truck chassis through a Roots type air pump to drive the air pump according to the radius of curve, cant, vehicle speed, etc. CONSTITUTION:On both ends of a truck chassis 6 are provided pneumatic springs 8 having a spring constant vertically soft and horizontally proper to support a car body 9 and interconnected through a Roots type air pump 12. During travelling from a transition curve inlet to a circular curve inlet or from circular curve outlet to the transition curve outlet, the air pump 12 is driven on the basis of the radius of curve, cant, vehicle speed, etc., to incline forcibly the car body for improving on-curve passing speed. By using the Roots type air pump capable of facilitating reversible variable speed running and unconditionally determining flow speed and quantity according to the rotational frequency and number of times can be simplified a mechanism for forcibly inclining the car body. |
