Abstract
A machine, such as a mobile asset, vehicle, or agricultural vehicle, includes a chassis, an adjustment system, and a wheel. The adjustment system replaces a conventional non-extendable leg connected between the chassis and the wheel of the machine. The adjustment system can extend and withdraw in length, such that the height of the machine can vary as needed.
Claims20
An adjustment system for adjusting the height of an agricultural machine, the adjustment system comprising:
- a base;
- a connection element;
- a hydraulic assembly adapted to contract and expand;
- a first rod fixed at a first end to the base and at a second end to the connection element;
- a second rod fixed at a first end to the base and at a second end to the connection element;
- a body defining a cavity for receiving the hydraulic assembly, the first and second rods extending through a length of the body;
- and
- a chassis connection assembly extending outwardly from one side of the body for connecting the body to a chassis of the agricultural machine,
- the connection element stabilizing the first and second rods at the first end of the first and second rods,
- the body adapted to move based on a characteristic of the hydraulic assembly, the body moving along the first and second rods,
- the chassis of the agricultural machine moving parallel to movement of the body.

An agricultural machine comprising:
- a chassis;
- a wheel;
- and
- an adjustment system for adjusting the height of the chassis with respect to the wheel, the adjustment system adapted to fix the chassis at a desired height with respect to the wheel, and the adjustment system coupled to both the chassis and the wheel, the adjustment system comprising:
- a hydraulic assembly for actuating the adjustment system, the hydraulic assembly adapted to contract and expand, wherein contraction of the hydraulic assembly lowers the chassis and expansion of the hydraulic assembly raises the chassis.
2 more elements
An agricultural machine comprising:
- a chassis;
- a wheel;
- an extendable leg connecting the chassis to the wheel;
- and
- an adjustment system comprising a hydraulic assembly for actuating the extendable leg, the hydraulic assembly comprising:
- a base connected to the wheel;
- a hydraulic chamber containing hydraulic fluid;
- and
- a hydraulic rod fixed to the base at a first end of the hydraulic rod, a second end of the hydraulic rod housed in the hydraulic chamber, the hydraulic rod having a collar at the second end, the collar preventing the hydraulic fluid from exiting the hydraulic chamber;
- wherein as the hydraulic fluid in the hydraulic chamber increases, the hydraulic fluid pushes more of the hydraulic rod out of the hydraulic chamber, causing the extendable leg to extend;
- and
- wherein as the hydraulic fluid in the hydraulic chamber decreases, more of the hydraulic rod enters the hydraulic chamber, causing the extendable leg to contract.
