Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
135 words
A differential lock release for an articulating vehicle comprising, an articulating joint including a bearing pivotally connecting one bogie to another bogie of the articulated vehicle, a cam mounted on one of the bogies, a follower mounted on the other bogie of the articulated vehicle, a differential lock control mechanism connected to the follower, control means operating a differential lock, a differential on a vehicle including differential locking means defining a differential clutch for releasing and locking said differential and providing differential and synchronous rotation of said gears, a wheel axle connected to one side gear and another wheel axle connected to another side gear, said control means connecting said differential lock control mechanism to said differential to operate said differential for differential and synchronous rotation of said axles responsive to articulation of said vehicle.
Claim 2
Dependent Claim
135 words
A differential lock release for an articulating vehicle comprising, an articulating joint including a bearing pivotally connecting one bogie to another bogie of the articulated vehicle, a cam mounted on one of the bogies, a follower mounted on the other bogie of the articulated vehicle, a differential lock control mechanism connected to the follower, control means operating a differential lock, a differential on a vehicle including differential locking means defining a differential clutch for releasing and locking said differential and providing differential and synchronous rotation of said gears, a wheel axle connected to one side gear and another wheel axle connected to another side gear, said control means connecting said differential lock control mechanism to said differential to operate said differential for differential and synchronous rotation of said axles responsive to articulation of said vehicle.
Claim 3
Dependent Claim
63 words
A differential lock release for an articulating vehicle as set forth in claim 1 wherein said differential lock control mechanism includes a lever pivotally mounted on said other bogie of said vehicle, means connecting the cam follower to one end of said lever, a linkage connected to the other end of said lever for operation of said control means for releasing said differential.
Claim 4
Dependent Claim
39 words
A differential lock release for an articulating vehicle as set forth in claim 1 wherein said control means includes a hydraulic valve, said differnetial locking means includes a hydraulic differential clutch operated through said valve for controlling said differential.
Claim 5
Dependent Claim
35 words
A differential lock release for an articulating vehicle as set forth in claim 1 wherein said control means includes a hydraulic valve, a spool in said hydraulic valve operated by said differential lock control mechanism.
Claim 6
Dependent Claim
65 words
A differential lock release for an articulating vehicle as set forth in claim 1 wherein said differential lock control mechanism includes a lever pivotally mounted on said other bogie carrying said follower, a push rod operated by said lever, a bellcrank pivotally connected to said push rod and pivotally connected to said control means for controlling said differential locking means when said vehicle is articulated.
Claim 7
Dependent Claim
67 words
A differential lock release for an articulating vehicle as set forth in claim 1 wherein said control means includes a hydraulic valve including, a mechanically operated valve spool for controlling flow of pressurized fluid to said locking means in said differential, a release spool in said hydraulic valve for releasing pressurized fluid in said differential locking means for releasing said differential for differential rotation of said axles.
Claim 8
Dependent Claim
37 words
A differential lock release for an articulating vehicle as set forth in claim 1 wherein said one bogie defines the rear bogie of said articulating vehicle, said other bogie defines the front bogie of said articulating vehicle.
Claim 9
Dependent Claim
28 words
A differential lock release for an articulating vehicle as set forth in claim 1 wherein said control means operates said differential clutch for releasing and locking said differential.
Claim 10
Dependent Claim
29 words
A differential lock release for an articulating vehicle as set forth in claim 1 wherein said differential locking means includes manual means for manually operating said differential locking means.
Claim 11
Dependent Claim
82 words
A differential lock release for an articulating vehicle as set forth in claim 1 including means defining a vertical pivoting axis of said articulating joint, said cam follower including a roller defining a vertical rotating axis, said cam defining a cam slot for receiving said roller in the rest position, a lever supporting said roller on said vertical axis, means defining a vertical pivoting axis for said lever on said other bogie to pivot in response to articulation of said articulating joint.
