Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
113 words
A transmission arrangement for a vehicle having a frame defining an outwardly facing opening and a mounting face located peripherally about the opening, comprising: a housing assembly having a mounting member and a transmission case, said mounting member being releasably connected to said frame at said mounting face and said transmission case being releasably connected to said mounting member and extending inwardly into said opening; transmission means for selectively providing one of a plurality of speed ratios and forward and reverse operation, said transmission means including an output pinion and being disposed substantially within said housing assembly; and a bevel gear intermeshingly connected to said output pinion and disposed within said housing assembly.
Claim 2
Dependent Claim
113 words
A transmission arrangement for a vehicle having a frame defining an outwardly facing opening and a mounting face located peripherally about the opening, comprising: a housing assembly having a mounting member and a transmission case, said mounting member being releasably connected to said frame at said mounting face and said transmission case being releasably connected to said mounting member and extending inwardly into said opening; transmission means for selectively providing one of a plurality of speed ratios and forward and reverse operation, said transmission means including an output pinion and being disposed substantially within said housing assembly; and a bevel gear intermeshingly connected to said output pinion and disposed within said housing assembly.
Claim 3
Dependent Claim
43 words
The transmission arrangement of claim 1 wherein the vehicle has a normal longitudinal direction of movement and wherein said mounting face and said opening face rearwardly, said housing assembly being of a construction sufficient for extending said transmission case forwardly into said opening.
Claim 4
Dependent Claim
37 words
The transmission arrangement of claim 2 wherein said transmission means includes a longitudinally extending output shaft having a front end and a rear end, said output shaft being connected to said output pinion at said front end.
Claim 5
Dependent Claim
62 words
The transmission arrangement of claim 1 wherein said transmission means is connected to said mounting member and said transmission case, said bevel gear is connected to said transmission case, and said housing assembly, said transmission means and said bevel gear are releasable as a unit from said frame in response to disconnecting said mounting member from said mounting face of said frame.
Claim 6
Dependent Claim
26 words
The transmission arrangement of claim 1 including a longitudinal axis and wherein said transmission means is substantially contained within said transmission case radially of said axis.
Claim 7
Dependent Claim
14 words
The transmission arrangement of claim 1 wherein said mounting member is an upright plate.
Claim 8
Dependent Claim
42 words
The transmission arrangement of claim 1 including a clutch assembly, a cover releasably connected to said mounting member and defining therewith a chamber, said clutch assembly being connected to said transmission means through said mounting member and being located in said chamber.
Claim 9
Dependent Claim
39 words
The transmission arrangement of claim 1 including a cover releasably connected to said mounting member and defining therewith a first chamber, and wherein said mounting member and said transmission case define a second chamber larger than said first chamber.
Claim 10
Dependent Claim
93 words
A transmission arrangement for a vehicle having a frame, comprising: a housing assembly having a mounting plate and a transmission case, said mounting plate being releasably connected to said frame and said transmission case being releasably connected to said mounting plate; constant mesh transmission means for selectively providing one of a plurality of speed ratios and forward and reverse operation, said constant mesh transmission means including an output pinion and being disposed substantially within said housing assembly; and a bevel gear intermeshingly connected to said output pinion and disposed within said housing assembly.
Claim 11
Dependent Claim
93 words
A transmission arrangement for a vehicle having a frame, comprising: a housing assembly having a mounting plate and a transmission case, said mounting plate being releasably connected to said frame and said transmission case being releasably connected to said mounting plate; constant mesh transmission means for selectively providing one of a plurality of speed ratios and forward and reverse operation, said constant mesh transmission means including an output pinion and being disposed substantially within said housing assembly; and a bevel gear intermeshingly connected to said output pinion and disposed within said housing assembly.
Claim 12
Dependent Claim
32 words
The transmission arrangement of claim 9 wherein said mounting plate and said transmission case define a relatively large chamber and said transmission means and said bevel gear are disposed in said chamber.
