Abstract
A shift interlock mechanism that requires an operator to press a brake mechanism before changing transmission gears to prevent extra motion in the transmission, insuring a smoother shifting operation. The shift interlock mechanism with a brake arm that moves in a first direction to stop motion of at least a first ground engaging drive wheel and a shift arm that moves in a second direction to change movement of a vehicle.
Claims25
A vehicle comprising:
- a frame;
- at least a first ground engaging steerable wheel operatively connected to said frame;
- at least a first ground engaging drive wheel operatively connected to said frame;
- a transmission assembly operatively connected to said drive wheel and supported by said frame;
- an engine operatively connected to said transmission and supported by said frame;
- a shift interlock mechanism comprising;
- a brake arm with at least a first end adapted to stop motion of said at least a first ground engaging drive wheel;
- a shift arm with at least a first end adapted to change movement of said vehicle;
- a biasing means operatively connecting said brake arm to said shift arm;
- and,
- an adjusting means for adjusting the position of said brake arm to said shift arm;
- said shift interlock mechanism operatively connected to said transmission;
- an operator station adapted to said frame, said operator station comprising:
- a braking member operatively connected to said brake arm;
- and,
- a shift lever operatively connected to said shift arm.
A shift interlock mechanism comprising:
- a brake arm with at least a first end adapted to stop motion of at least a first ground engaging drive wheel;
- a shift arm with at least a first end adapted to change movement of an associated vehicle;
- and,
- a cable operatively connecting said brake arm to said shift arm.
A shift interlock mechanism comprising:
- a brake arm with at least a first end adapted to stop motion of at least a first ground engaging drive wheel;
- a shift arm with at least a first end adapted to change movement of an associated vehicle;
- a biasing means operatively connecting said brake arm to said shift arm;
- and,
- an adjusting means adapted to modify position of said brake arm and position of said shift arm;
A method of shifting a transmission comprising the steps of:providing:
- a frame;
- at least a first ground engaging steerable wheel operatively connected to said frame;
- at least a first ground engaging drive wheel operatively connected to said frame;
- a transmission assembly operatively connected to said drive wheel and supported by said frame;
- an engine operatively connected to said transmission and supported by said frame;
- a shift interlock mechanism comprising;
- a brake arm with at least a first end adapted to stop motion of said at least a first ground engaging drive wheel;
- a shift arm with at least a first end adapted to change movement of said vehicle;
- said shift arm comprising a plurality of grooves;
- a member adapted to be received in one of said plurality of grooves;
- a biasing means operatively connecting said brake arm to said shift arm;
- and,
- an adjusting means for adjusting the position of said brake arm to said shift arm;
- said shift interlock mechanism operatively connected to said transmission;
- an operator station adapted to said frame, said operator station comprising:
- a braking member operatively connected to said brake arm;
- and,
- a shift lever operatively connected to said shift arm.
