A method of using a torsion bar type long travel adjustable suspension for a vehicle, the suspension comprising a wheel assembly (6); the wheel axle of the wheel assembly is connected with the guide upright post (2); a rack is arranged on the side wall of the guide upright post; the rack is meshed with a gear piece in the guide rail seat (1); the gear piece in the guide rail seat (1) is connected with a worm wheel of the worm and gear transmission mechanism (4) through an elastic torsion bar (3); the worm of the worm gear and worm transmission mechanism (4) is driven to rotate by the motor (5), and the worm gear and worm transmission mechanism drives the guide rail seat to vertically lift at the rack of the guide upright post through the torsion bar.
The guide rail seat is connected with the automobile body; when the guide rail seat vertically ascends and descends at the rack of the guide upright post, the ground clearance of the automobile body is changed.
The elastic torsion bar comprises a torsion spring; the gear piece in the guide rail seat is connected with a worm wheel of the worm and gear transmission mechanism through a torsion spring of the elastic torsion bar.
The elastic torsion bar synchronously rises and falls along with the guide rail seat.
When the height of the guide rail seat is changed, the elastic force output of the torsion spring is unchanged.
The worm and gear transmission mechanism has reverse self-locking capability; the worm and gear transmission mechanism forms an impact force isolation mechanism between the wheel and the motor.
When the wheels move up and down to enable the guide upright post to move up and down, the elastic torsion bar drives the gear piece in the guide rail seat (1) through elasticity, so that the guide upright post is reset.
The use method of the adjustable suspension comprises the following steps of;
a1, when the length of the suspension is not required to be adjusted, the motor does not rotate, the guide upright post receives impact force brought by wheels to slide up and down, and the elastic torsion bar provides reset force to reset the guide upright post;
a2, the rack is meshed with a gear piece in the guide rail seat to form a gear-rack mechanism; when the length of the suspension needs to be adjusted, the motor drives the torsion bar to rotate through the worm and gear transmission mechanism, and the torsion bar drives the guide upright post to slide up and down or the guide rail seat to lift through the gear and rack mechanism, so that the adjustment of the ground clearance of the vehicle body is realized.
The invention has simple and reliable structure and low cost, and can realize the large-stroke adjustable suspension without oil and gas media.
The scheme of the invention adopts a rack-and-pinion type structure, so that large-stroke adjustment can be realized.
The torsion bar structure is adopted in the scheme of the invention, so that the torsion bar structure can realize the function of transmitting and adjusting power while transmitting rebound force, further simplifies the structure, occupies small transverse space of the vehicle and can enlarge available space in the vehicle.
According to the scheme, the worm and gear is adopted for transmission, so that a large transmission ratio can be realized, the ground clearance of the vehicle can be adjusted by large lifting force, and meanwhile, the fragile part can be protected by means of the characteristic of reverse self-locking of the worm and gear.
