Tag axle suspension system with tire at lowest point when lifted |
摘要 |
A tag axle suspension system can include a tire and at least one hanger bracket pivotable relative to a vehicle frame to deployed and lifted configurations. In the lifted configuration, the tire can be a lowest component of the suspension system, and can be a first component to engage a road surface. A tag axle suspension system can include an air spring and a travel limit device that limits compression of the air spring in a lifted configuration of a hanger bracket. A tag axle suspension system can include an axle, a suspension arm pivotably connected between a hanger bracket and the axle, and a travel limit device that limits displacement of the suspension arm in a lifted configuration of the hanger bracket. The travel limit device can limit displacement of the axle toward an air spring support in the lifted configuration of the hanger bracket. |

1. A tag axle suspension system, comprising:
at least one tire; at least one hanger bracket pivotable relative to a vehicle frame to deployed and lifted configurations; at least one air spring which, in the deployed configuration, suspends an air spring support pivotably attached to the vehicle frame above an axle of the suspension system; and at least one travel limit device which, in the lifted configuration, limits displacement of the axle toward the air spring support, wherein, in the lifted configuration, the tire comprises a first component of the suspension system engageable with a road surface. |
