Abstract
Abstract Apparatus is described for use in a vehicle having a forward motion transmission operatively connected between an engine and the output shaft connecting the drive wheel and a reverse drive mechanism arranged to be operatively connected to the output shaft for driving the vehicle in reverse. A speed change shift device is arranged to operate the forward motion transmission and the reverse drive mechanism so as to prevent simultaneous operation of the two apparatus.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
178 words
A vehicle comprising: a driving wheel; an output shaft drivingly connected to said driving wheel; an internal combustion engine operatively connectable to said output shaft through gear train means defining a variable forward motion transmission; a reverse drive motor operatively connectable to said output shaft through a gear train defining a reverse motion transmission; a speed change shift device for selectively connecting either said forward motion transmission or said reverse motion transmission to said output shaft, said speed change shift device including a movable operator containing a plurality of mutually spaced cam means including first cam means operable when said speed change shift device is in a first position to operably connect said forward motion transmission to said output shaft to the exclusion of said reverse motion transmission, and second cam means operable when said operator is in a second position spaced from said first position to operably connect said reverse motion transmission to said output shaft to the exclusion of said forward motion transmission; and means for moving said speed change shift device operator between said positions.
Claim 2
Dependent Claim
178 words
A vehicle comprising: a driving wheel; an output shaft drivingly connected to said driving wheel; an internal combustion engine operatively connectable to said output shaft through gear train means defining a variable forward motion transmission; a reverse drive motor operatively connectable to said output shaft through a gear train defining a reverse motion transmission; a speed change shift device for selectively connecting either said forward motion transmission or said reverse motion transmission to said output shaft, said speed change shift device including a movable operator containing a plurality of mutually spaced cam means including first cam means operable when said speed change shift device is in a first position to operably connect said forward motion transmission to said output shaft to the exclusion of said reverse motion transmission, and second cam means operable when said operator is in a second position spaced from said first position to operably connect said reverse motion transmission to said output shaft to the exclusion of said forward motion transmission; and means for moving said speed change shift device operator between said positions.
Claim 3
Dependent Claim
16 words
The vehicle according to claim 1 in which said reverse drive motor is an electric motor.
Claim 4
Dependent Claim
21 words
The vehicle according to claim 2 in which said electric motor is dedicated exclusively to reverse driving of said output shaft.
Claim 5
Dependent Claim
103 words
A vehicle according to claim 1 in which said reverse motion transmission includes an idler shaft containing gear means for connection with said output shaft, said idler shaft being movable between longitudinally spaced positions by movement of said speed change shift device operator to connect said reverse motion transmission gear means to said output shaft when said operator is in a position for disconnecting said forward motion transmission gear means from said output shaft and to disconnect said reverse motion transmission gear means from said output shaft when said operator is in a position for connecting said forward motion transmission gear means thereto.
Claim 6
Dependent Claim
126 words
A vehicle according to claim 4 in which said speed change shift device includes: an axially movable shift fork shaft; cam-operated shift fork means slidably mounted on said shift fork shaft; said first cam means on said operator being operative to move said shift fork means along said shift fork shaft to connect said forward motion transmission gear means to said output shaft and said second cam means on said operator being operative to move said shift fork shaft axially; and a pivotably mounted lever connecting said shift fork shaft to said idler shaft for moving said idler shaft in response to movement of said shift fork shaft between positions on which said reverse motion transmission is either connected to or disconnected from said output shaft.
Claim 7
Dependent Claim
54 words
A vehicle according to claim 5 in which said speed change shift device operator comprises a rotatably mounted cylindrical drum having circumferential cams thereon containing a profile for axially shifting said shift forks along said shift fork shaft in response to rotational movement of said drum, and manually operated means for rotating said drum.
Claim 8
Dependent Claim
64 words
A vehicle according to claim 6 in which said speed change shift device includes a plurality of individually shiftable cam-operated shift forks on said shift fork shaft for selectively varying the speed generated by said forward transmission means and in which said drum rotating means includes indexing means for rotating said drum in indexed steps between the respective of the positions of said drum.
Claim 9
Dependent Claim
14 words
A vehicle according to claim 7 including a foot-operated pedal for rotating said drum.
