Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
92 words
A vehicle transmission and brake comprising a transmission housing, an input shaft rotatably mounted in said housing, a drive shaft driving a differential, bearings rotatably supporting each end of said drive shaft in said housing, at least two gearsets on said shafts, a clutch collar reciprocally mounted on said drive shaft between said bearings for selectively and alternatively connecting each of said gearsets to drive said drive shaft, at least one brake disk nonrotatably connected to said clutch collar, a vehicle brake including said brake disk for selectively braking said drive shaft.
Claim 2
Dependent Claim
92 words
A vehicle transmission and brake comprising a transmission housing, an input shaft rotatably mounted in said housing, a drive shaft driving a differential, bearings rotatably supporting each end of said drive shaft in said housing, at least two gearsets on said shafts, a clutch collar reciprocally mounted on said drive shaft between said bearings for selectively and alternatively connecting each of said gearsets to drive said drive shaft, at least one brake disk nonrotatably connected to said clutch collar, a vehicle brake including said brake disk for selectively braking said drive shaft.
Claim 3
Dependent Claim
23 words
A vehicle transmission and brake as set forth in claim 1 wherein said drive shaft drives a pinion adapted for driving said differential.
Claim 4
Dependent Claim
19 words
A vehicle transmission and brake as set forth in claim 1 wherein said brake defines a vehicle parking brake.
Claim 5
Dependent Claim
27 words
A vehicle transmission and brake as set forth in claim 1 wherein said clutch collar defines high, low and neutral positions for selectively operating a range transmission.
Claim 6
Dependent Claim
19 words
A vehicle transmission and brake as set forth in claim 1 wherein said brake defines a caliper disk brake.
Claim 7
Dependent Claim
33 words
A vehicle transmission and brake as set forth in claim 1 wherein said transmission defines a range transmission driven by a main transmission to multiply the overall speed ratio of the drive line.
Claim 8
Dependent Claim
18 words
A vehicle transmission and brake as set forth in claim 1 wherein said brake defines a mechanical brake.
Claim 9
Dependent Claim
64 words
A vehicle transmission and brake as set forth in claim 1 including a clutch sleeve received within said clutch collar, means defining a spline connection between said clutch sleeve and said drive shaft, means defining a spline connection between said clutch sleeve and said clutch collar to provide reciprocal movement between said clutch collar and said sleeve and said sleeve and said drive shaft.
Claim 10
Dependent Claim
29 words
A vehicle transmission and brake as set forth in claim 1 including manual means for selectively and alternatively reciprocating said clutch collar between a high, low and neutral positions.
Claim 11
Dependent Claim
82 words
A vehicle transmission and brake as set forth in claim 1 including said input shaft, said gearsets selectively driving between said input shaft and said drive shaft, a clutch sleeve embracing said drive shaft and received within said clutch collar, means defining a spline connection between said clutch collar and said clutch sleeve and between said clutch sleeve and said drive shaft, means for shifting said clutch collar to selectively shift said transmission, manual means for selectively engaging and disengaging said brake.
