INTERNAL MECHANICAL AUTOMATIC TRANSMISSION ASSEMBLY

摘要

An internal mechanical automatic transmission assembly for discrete shifting of transmission ratios for forward travel, comprising a plurality of interconnectable transmission ratio producing units constituted by PTCs arranged side by side and being concatenatingly engageable and disengageable one to the adjacent in relation to a rotational speed resulting from a torque input to the transmission assembly, each of the PTCs being designed to affect a transmission ratio to thereby produce an overall transmission ratio over the transmission assembly. The transmission according to the present invention may further comprise one or more multiplication assembly
