Abstract
A control system for coordinated control of the throttle and transmission of a vehicle includes shift means for shifting the control linkage of the vehicle so that forward and reverse of the vehicle may be obtained by the depression of a control pedal in the same direction.
Claims8
Control mechanism for coordinated control of the motor speed regulator and transmission of a vehicle for both forward and reverse direction by single directional movement of a single control pedal, comprising:
- an operator's control pedal supported for forward rocking movement from a neutral position, said operator's control pedal being coupled to said motor speed regulator;
- a shaft;
- a shifting block supported on said shaft for axial movement therealong and being rotatable about the axis thereof, said shifting block having an arm extending therefrom for effecting rotational movement of said shifting block about said axis thereof;
- link means connecting said operator's control pedal to said shifting block arm for forward rocking motion therewith;
- a forward transmission control member mounted on said shaft to one side of said shifting block for transmitting a forward control motion to a transmission control member of a transmission upon being rotated in synchronism with said shifting block;
- a reverse transmission control member mounted on said shaft on the opposite side of said shifting block for transmitting a reverse control motion to said transmission control member upon being rotated in synchronism with said shifting block;
- and
- shifting means connected to said shifting block for shifting said block axially along said shaft to selected ones of a neutral position, a forward position at which said shifting block engages said forward control member and a reverse position at which said shifting block engages said reverse control member.
