Abstract
The present invention gearshift assembly for a motorized vehicle manual transmission comprises a gearshift lever having an upper ball which determines a crossover pivot ratio and a lower ball which determines a different linear pivot ratio. Also, a uniquely shaped socket transfers the upper ball's crossover movement and the lower ball's linear movement to the attached shift rail. The socket has a pair of lateral walls, a short forward facing wall, a short rearward facing wall, and a cavity therewithin.
Claims15
A gearshift assembly for permitting a vehicle operator to selectively shift between a plurality of ratio gear positions within a multi-speed manual transmission, comprising:
- a shift mechanism being operable to translate in a linear direction and being operable to rotate about its linear axis, said shift mechanism having a plurality of shift forks attached thereto for controlling a plurality of transmission gears;
- a gearshift lever having a pivot means thereupon for providing pivotal movement in said linear direction and a neutral crossover direction, said gearshift lever further having an upper bearing surface which determines a crossover pivot ratio and a lower bearing surface which determines a different linear pivot ratio;
- and
- a socket being operable to transfer said upper bearing surface's crossover movement and said lower bearing surface's linear movement to said attached shift mechanism, said shift mechanism attached to said socket substantially below said lower bearing surface.
