Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
A pivoting axle system for a terrain vehicle which comprises in combination, a first and a second rigid wheel axle disposed for supporting a chassis portion of the vehicle, said first and second axles each being centrally suspended and vertically pivotable about a pivotal point, a first and a second co-acting movable member each disposed on opposite sides of the pivotal point and coupled between the axle and a chassis portion of the vehicle, means for interconnecting all of said co-acting movable members to a control means for controlling operation of each co-acting movable member on the first rigid wheel axle relative to a correspondingly disposed co-acting movable member on the second rigid wheel axle, said first axle being caused to oppositely pivot relative to said second axle by interconnection of the co-acting members.
Claim 2
Dependent Claim
134 words
A pivoting axle system for a terrain vehicle which comprises in combination, a first and a second rigid wheel axle disposed for supporting a chassis portion of the vehicle, said first and second axles each being centrally suspended and vertically pivotable about a pivotal point, a first and a second co-acting movable member each disposed on opposite sides of the pivotal point and coupled between the axle and a chassis portion of the vehicle, means for interconnecting all of said co-acting movable members to a control means for controlling operation of each co-acting movable member on the first rigid wheel axle relative to a correspondingly disposed co-acting movable member on the second rigid wheel axle, said first axle being caused to oppositely pivot relative to said second axle by interconnection of the co-acting members.
Claim 3
Dependent Claim
29 words
The pivoting axle system of claim 1 wherein said co-acting movable members are pressure cylinders and wherein said interconnecting means are pipes for providing coupling between the pressure cylinders.
Claim 4
Dependent Claim
61 words
The pivoting axle system of claim 2 wherein the pressure cylinders are single-acting and the control means is a distributing valve arranged for coupling combinations of the pipes such that the pressure pipes to side-situated pairs of pressure cylinders and the pressure pipes to the pairs of pressure cylinders situated on the respective axles can be commonly connected or individually blocked.
Claim 5
Dependent Claim
53 words
The pivoting axle system of claim 3 wherein a setting valve is shunt connected to at least one pair of the pressure pipes for a pair of cylinders on one axle, the setting valve obtaining pressure medium from a source of pressure and with reversability distributes the pressure medium to the pressure pipes.
Claim 6
Dependent Claim
40 words
The pivoting axle system of claim 1 wherein said co-acting members are arranged to be brought into such co-action that the common plane for the chassis portion can be angularly set relative to the axles in the respective pivoting plane.
Claim 7
Dependent Claim
55 words
The pivoting axle system of claim 1 wherein the chassis portion supported by the first rigid wheel axle and the chassis portion supported by the second rigid wheel axle are coupled to each other by a vertical pin disposed for allowing angular movement in a horizontal plane and rigidly joined movement in a vertical plane.
