Vehicle cab mounting means

Claim 2

A mounting device for connecting a vehicle cab to a supporting vehicle frame and for cushioning relative movement therebetween, said mounting device comprising a first bracket member adapted to be rigidly secured to said vehicle cab, a second bracket member adapted to be rigidly connected to said vehicle frame adjacent the first bracket member, one of said bracket members being formed with a block member so when said first and second bracket members are secured to the vehicle cab and the vehicle frame at least one pair of opposed seating surfaces are provided above and below a horizontal axis passing through the block member, an air spring adapted to be located between each pair of opposed seating surfaces, a manually controlled valve adapted to connect the air springs located on one side of said horizontal axis to a source of pressurized air for selectively varying the air pressure therein, and a height control valve adapted to connect the air springs located on the other side of said horizontal axis to the source of pressurized air for maintaining the vehicle cab at a fixed height relative to the vehicle frame.

Claim 3

In a motor vehicle having a vehicle cab and a frame including a pair of laterally spaced side rails and a cross member interconnecting the side rails adjacent the rear end of the vehicle cab, a mounting device for connecting said rear end of the vehicle cab to said cross member and cushioning relative movement therebetween, said mounting device comprising a first bracket member rigidly secured to said vehicle cab, a second bracket member rigidly connected to said cross member adjacent the first bracket member, one of said bracket members being formed with a block member so when said first and second bracket members are secured to the vehicle cab and the cross member at least one pair of opposed seating surfaces are provided above and below a horizontal axis passing through the block member, an air spring located between each pair of opposed seating surfaces, a source of pressurized air, a manually controlled valve adapted to connect the air springs located on one side of said horizontal axis to said source of pressurized air for selectively vaying the air pressure therein, and a height control valve adapted to connect the air springs located on the other side of said horizontal axis to said source of pressurized air for normally maintaining the vehicle cab at a fixed height relative to the vehicle frame.

Claim 4

In a motor vehicle having a vehicle cab and a frame including a pair of laterally spaced side rails and a cross member interconnecting the side rails adjacent the rear end of the vehicle cab, a mounting device for connecting said rear end of the vehicle cab to said cross member and cushioning relative movement therebetween, said mounting device comprising a first bracket member rigidly secured to said vehicle cab, a second bracket member rigidly connected to said cross member adjacent the first bracket member, one of said bracket members being formed with a block member so when said first and second bracket members are secured to the vehicle cab and the cross member at least one pair of opposed seating surfaces are provided above and below a horizontal axis passing through the block member, an air spring located between each pair of opposed seating surfaces, a source of pressurized air, a manually controlled valve adapted to connect the air springs located on one side of said horizontal axis to said source of pressurized air for selectively vaying the air pressure therein, and a height control valve adapted to connect the air springs located on the other side of said horizontal axis to said source of pressurized air for normally maintaining the vehicle cab at a fixed height relative to the vehicle frame.

Claim 5

In a motor vehicle having a vehicle cab and a frame including a pair of laterally spaced side rails and a cross member interconnecting the side rails adjacent the rear end of the vehicle cab, a mounting device for connecting the rear end of the vehicle cab to said cross member and cushioning relative movement therebetween, said mounting device comprising a first bracket member ridigly secured to said vehicle cab and extending rearwardly therefrom, a second bracket member rigidly connected to said cross member adjacent the first bracket member, and together with said cross member providing three outer seating surfaces, said first bracket member being formed with a block member having three inner seating surfaces so when said first and second bracket members are secured to the vehicle cab and the cross member three pairs of circumferentially spaced opposed seating surfaces are provided, an air spring located between each pair of opposed seating surfaces a source of pressurized air, a manually controlled valve connecting one of the air springs to said source of pressurized air for selectively varying the air pressure therein, and a height control valve connecting the other of the air springs to the source of pressurized air for normally maintaining the vehicle cab at a fixed height relative to the vehicle frame.

Claim 6

In a motor vehicle having a vehicle cab and a frame including a pair of laterally spaced side rails and a cross member interconnecting the side rails adjacent the rear end of the vehicle cab, a mounting device for connecting the rear end of the vehicle cab to said cross member and cushioning relative movement therebetween, said mounting device comprising a first bracket member ridigly secured to said vehicle cab and extending rearwardly therefrom, a second bracket member rigidly connected to said cross member adjacent the first bracket member, and together with said cross member providing three outer seating surfaces, said first bracket member being formed with a block member having three inner seating surfaces so when said first and second bracket members are secured to the vehicle cab and the cross member three pairs of circumferentially spaced opposed seating surfaces are provided, an air spring located between each pair of opposed seating surfaces a source of pressurized air, a manually controlled valve connecting one of the air springs to said source of pressurized air for selectively varying the air pressure therein, and a height control valve connecting the other of the air springs to the source of pressurized air for normally maintaining the vehicle cab at a fixed height relative to the vehicle frame.
