Abstract
A method for lowering a vehicle chassis to a required vertical position, the vehicle including only two sets of running gear, namely a front set of running gear and a rear set of running gear, each wheel of the sets of running gear being associated with a parking brake, the method including the following successive steps: when the chassis is in its high running position, actuating the parking brake only for all of the wheels of one of the two sets of running gear; lowering the chassis to its low position resting on the ground; and actuating the parking brake for all of the wheels of the other of the two sets of running gear.
Claims8
A method for lowering a vehicle chassis with a controllable vertical position, the vehicle being designed so that its chassis can be moved between a high running position and a low position in which the chassis is supported on the ground, the vehicle also including a plurality of wheels, and, associated with each wheel:
- a wheel-bearing suspension arm, the arm being pivotably mounted on the chassis;
- a suspension arm actuator, arranged between the suspension arm and the chassis, the actuator being configured to control an angular position of the arm relative to the chassis, in order to vary the vertical position of the chassis,
- the vehicle including only two running gears, namely a front running gear and a rear running gear, each wheel of the running gears being associated with a parking brake, wherein the method for lowering the vehicle chassis comprises the following sequence of steps:
- when the chassis is in the high running position, actuating the parking brake only for all of the wheels of one of the two running gears;
- lowering of the chassis to its low position supported on the ground;
- and
- actuating the parking brake for all of the wheels of the other of the two running gears.
