Abstract
A corner module apparatus for a vehicle includes a driving unit configured to provide driving power to a wheel of the vehicle; a braking unit, coupled with the driving unit, configured to apply or release braking power; an upper arm module, connected to the driving unit, adjustable to vary a camber angle of the wheel; a lower arm module, connected to the driving unit, configured to absorb road surface impact while the vehicle moves; and a steering unit configured to support the upper arm module and the lower arm module, and adjust a steering angle of the wheel.
Claims14
A corner module apparatus for a vehicle, comprising:
- a driving unit configured to provide driving power to a wheel of the vehicle;
- a braking unit, coupled with the driving unit, configured to apply or release braking power;
- a steering unit configured to adjust a steering angle of the wheel;
- an upper arm module, connected between the steering unit and the driving unit, adjustable to vary a camber angle of the wheel;
- and
- a lower arm module, connected between the steering unit and the driving unit, configured to absorb road surface impact while the vehicle moves, wherein the lower arm module is spaced apart from the upper arm module and is configured to rotate in accordance with up and down movements of the wheel, independent of the upper arm module,
- wherein the upper arm module comprises:
- a first upper bracket, rotatably connected to the driving unit,
- a second upper bracket, rotatably connected to the steering unit, spaced apart from the first upper bracket,
- an upper link unit disposed between the first upper bracket and the second upper bracket and being configured to vary a distance between the first upper bracket and the second upper bracket, and
- a first driving module, disposed between the first upper bracket and the second upper bracket, configured to vary the distance between the first upper bracket and the second upper bracket by adjusting an internal angle of the upper link unit,
- wherein the upper link unit comprises:
- a pair of first upper links having first ends rotatably connected to the first upper bracket, wherein the pair of first upper links have the same length and angles of the pair of first upper links that are inclined are identically set, and
- a pair of second upper links having first ends rotatably connected to the second upper bracket and second ends rotably connected to second ends of the pair of first upper links, respectively, wherein the pair of second upper links have the same length and angles of the pair of second upper links that are inclined are identically set, and
- wherein the first driving module comprises:
- a first actuator configured to generate rotatory power from an external power source,
- a first lead screw, disposed on the first actuator to move forward and backward, configured to widen or narrow a gap between the first upper bracket and the second upper bracket in a moving direction thereof, and
- a first nut screw configured to convert a rotary motion of the first actuator into a rectilineal and reciprocating motion of the first lead screw.
