Abstract
A system configured to raise and lower a chassis of a vehicle. The system includes a damper with a first end connected to the chassis and a second end that is opposite to the first end. An actuation assembly includes a rotatable arm and a motor configured to rotate the rotatable arm, the rotatable arm is connected to both the second end of the damper and a control arm of the vehicle. Rotation of the rotatable arm by the motor moves the damper between a raised position to raise the chassis and a lowered position to lower the chassis.
Claims13
A system configured to raise and lower a chassis of a vehicle, the system comprising:
- a damper including a first end connected to the chassis and a second end that is opposite to the first end;
- and
- an actuation assembly including a rotatable arm and a motor configured to rotate the rotatable arm, the rotatable arm is connected to both the second end of the damper and a control arm of the vehicle;
- wherein:
- rotation of the rotatable arm by the motor moves the damper between a raised position to raise the chassis and a lowered position to lower the chassis;
- the actuation assembly further includes a drive shaft extending from the motor to the rotatable arm, the drive shaft is connected to the rotatable arm to rotate the rotatable arm;
- and
- the drive shaft is directly affixed to the rotatable arm.
A system configured to raise and lower a chassis of a vehicle, the system comprising:
- a damper including a first end connected to the chassis and a second end that is opposite to the first end;
- an actuation assembly including a rotatable arm and a motor configured to rotate the rotatable arm, the rotatable arm is connected to both the second end of the damper and a control arm of the vehicle;
- and
- a control module configured to control the motor and receive signals from a remote communication device, in response to receipt of a first signal the control module is configured to operate the motor to rotate the rotatable arm in a first direction to lower the damper and the chassis, and in response to receipt of a second signal the control module is configured to operate the motor to rotate the rotatable arm in a second direction that is opposite to the first direction to raise the damper and raise the chassis;
- wherein the actuation assembly further includes:
- a first drive shaft extending from the motor;
- a drive sprocket coupled to the first drive shaft such that the drive sprocket rotates with the first drive shaft;
- a driven sprocket coupled to the drive sprocket by a flexible drive member such that rotation of the drive sprocket rotates the flexible drive member, which rotates the driven sprocket;
- and
- a second drive shaft rigidly connected to the driven sprocket and rigidly connected to the rotatable arm such that rotation of the driven sprocket rotates the second drive shaft and the rotatable arm.
A system configured to raise and lower a chassis of a vehicle, the system comprising:
- a damper including a first end connected to the chassis and a second end that is opposite to the first end;
- a rotatable arm connected to both the second end of the damper and a control arm of the vehicle;
- and
- a motor including a drive shaft extending through the control arm, the motor configured to rotate the drive shaft in a first direction and a second direction that is opposite to the first direction,
- wherein rotation of the drive shaft in the first direction rotates the rotatable arm to lower the damper and the chassis, and rotation of the drive shaft in a second direction that is opposite to the first direction rotates the rotatable arm to raise the damper and the chassis.
