Abstract
A dual suspension system includes a chassis, a suspension arm rotatably connected to the chassis, a wheel connection connected coupled to the suspension arm, a first lock connected to the chassis and the suspension arm, and a second lock connected between a differential housing and the chassis. The first and second locks each have an unlocked state and a locked state. When the first lock is unlocked, and the second lock is locked, the vehicle substantially provides independent suspension. When the first lock is locked, and the second lock is unlocked, the vehicle substantially provides solid axle suspension.
Claims15
A dual mode suspension system for a vehicle, comprising:
- a chassis;
- a suspension support;
- and,
- a suspension directly or indirectly coupled with said chassis and said suspension support, said suspension having an independent suspension mode and a solid axle suspension mode.
A dual mode suspension system for a vehicle, comprising:
- a chassis;
- a suspension support directly or indirectly coupled with said chassis;
- a suspension having an upper suspension arm and a lower suspension arm, each coupled to the suspension support;
- and
- a lock operatively coupling either of the upper suspension arm or the lower suspension arm to the suspension support to position the suspension between an independent suspension mode and a solid axle suspension mode.
A dual mode suspension system for a vehicle, comprising:
- a chassis;
- a suspension support;
- a first suspension positioned at a right side of the vehicle, the first suspension having a first upper suspension arm and a first lower suspension arm, each of the first upper suspension arm and the first lower suspension arm coupled to the suspension support;
- a second suspension positioned at a left side of the vehicle and aligned with the first suspension, said second suspension having a second upper suspension arm and a second lower suspension arm, each of the second upper suspension arm and the second lower suspension arm coupled to the suspension support;
- a first lock coupling either the first upper suspension arm or the first lower suspension arm to the suspension support and either the second upper suspension arm or the second lower suspension arm to the suspension support in a solid axle suspension mode, and not directly coupling the first and second upper and lower suspension arms with the chassis in an independent suspension mode;
- and
- a second lock coupling the suspension support to the chassis in the independent suspension mode and not directly coupling the suspension support with the chassis in the solid axle suspension mode.
A method for providing a dual mode suspension system for a vehicle, the method comprising:
- providing a chassis;
- providing a suspension support;
- and,
- providing a suspension directly or indirectly coupled with said chassis and said suspension support, said suspension having an independent suspension mode and a solid axle suspension mode.
A method for providing dual mode suspension system for a vehicle, the method comprising:
- providing a chassis;
- providing a suspension support;
- providing a first suspension positioned at a right side of the vehicle, the first suspension having a first upper suspension arm and a first lower suspension arm, each of the first upper suspension arm and the first lower suspension arm coupled to the suspension support;
- providing a second suspension positioned at a left side of the vehicle and aligned with the first suspension, said second suspension having a second upper suspension arm and a second lower suspension arm, each of the second upper suspension arm and the second lower suspension arm coupled to the suspension support;
- coupling, using a first lock, either the first upper suspension arm or the first lower suspension arm to the suspension support and either the second upper suspension arm or the second lower suspension arm to the suspension support in a solid axle suspension mode, and not directly coupling the first and second upper and lower suspension arms with the chassis in an independent suspension mode;
- and
- coupling, using a second lock, the suspension support to the chassis in the independent suspension mode and not directly coupling the suspension support with the chassis in the solid axle suspension mode.
