ABSTRACT:
A spring biased shifter assembly is disclosed for use with a manually operated multi-speed transmission. The shifter assembly includes a shift tower to which a shift lever of a shift mechanism is pivotally mounted. A pair of spaced apart single leaf flat springs continuously downwardly bias a portion of the shift mechanism, thereby biasing the shift lever to a neutral position. The springs are located within slots defined by the shift tower and are further held in place by a cover that is fastened to the shift tower. The particular configuration of the single leaf flat springs provides improved shifter feel, substantially eliminates play in the shifter assembly, and automatically self-centers the shift lever to a neutral position while maintaining a constant downward biasing force thereon. The single leaf flat springs are preferably constructed of a fiber reinforced composite material, thereby providing excellent noise attenuation properties.
