PCT No. PCT/EP92/01165 Sec. 371 Date Nov. 24, 1993 Sec. 102(e) Date Nov. 24, 1993 PCT Filed May 23, 1992 PCT Pub. No. WO92/21899 PCT Pub. Date Dec. 10, 1992.A gearshift device for electrically controlled transmissions is provided having a shifting lever pivotable in two parallel planes and guided in slides which have a connecting link only in the area of a neutral shifting position. Such gearshift devices are used particularly in construction machines. By way of a lock, which is activated below an admissible speed, a shift to the neutral position and into the opposite direction of travel is prevented. At higher speeds, accidental faulty shifts are prevented by a step-by-step gearshift mechanism. The locks, according to the invention, require only few regulation measures since they contain two mutually independent locking systems. |
