Spiral drive mechanism, particularly for mechanical vehicles, land and marine machines

Abstract

Spiral drive mechanism, particularly for mechanical vehicles, land and water machines, comprises of deformable spiral (1) of spindle shape, on one side resting on a rocker arm (2) with bearing, attached to the vehicle through a moving joint, through an axle (3) that moves the front part of the spiral in vertical, longitudinal and transverse axis. On the other side, it rests on a pendulum-moving driving axle of the vehicle (4), propelling rotating motion of the spiral and thus causing movement of the vehicle.

Claims

1. A spiral drive mechanism, particularly for mechanical vehicles, land and water machines, wherein the deformable drive spiral of spindle shape (1) rests on one side on a rocker arm (2) with bearing, wherein the rocker arm is attached to the vehicle through a moving joint (3), which directs the location of the beginning of the spiral relative to the vehicle in longitudinal, vertical and transverse axis, and on the other side, the spiral (1) is attached to the driving axle of the engine (4), installed to the vehicle through a pendulous joint in its longitudinal axis, which propels the rotary motion of the spiral (1) in its longitudinal axis, constituting the drive of the vehicle.

2. The spiral drive mechanism, particularly for mechanical vehicles, land and water machines, assembled, according to claim 1, wherein it consists of multiple spiral drives operating independently in longitudinal axis of the vehicle, inverted relative to each other by 180 degrees, with the driving axles (4) towards each other, and situated in assemblies at both sides of the vehicles.

3. The spiral drive mechanism, particularly for mechanical vehicles land and water machines, according to claim 1, wherein the bearing rocker (2) attached to the vehicle through the moving joint (3), rotating along the longitudinal axis of the vehicle, presses onto the ground through the spiral (1), lifting the vehicle and being independent from the drive axle, rotating along the transverse axis of the vehicle (4).

Description

(1) The subject of invention is presented in embodiment on the figure, where

(2) FIG. 1 presents the top view of the drive, and FIG. 1a presents the perspective view,

(3) FIG. 2 presents view from the top of the vehicle, with rocker arms shortened and spirals set as rollers,

(4) FIG. 3 shows the turning of the drive in transverse axis, from the top,

(5) FIG. 4 and FIG. 5 shows the side view of operation of the drive, moved in vertical axis,

(6) FIG. 6, shows the front view, and

(7) FIG. 7, shows the side view of lifting and lowering of the vehicle through oscillatory rotation of the drives in longitudinal axis of the vehicle,

(8) FIG. 8 shows the top view of vehicle with multiplied spiral drive,

(9) FIG. 9 shows the side view of vehicle with multiplied spiral drive.

(10) The benefit of the invented solution is that a vehicle equipped with a spiral drive, through elongation of the deformable spiral (1), FIG. 2 or movement of its front part in horizontal plane FIG. 3 or vertical plane FIG. 4; FIG. 5, FIG. 9 is able to adapt to land in such way that optimum parameters of the vehicle movement on various grounds, including: rocks, sand, ice, water, stairs, construction obstacles are ensured. Rotation of the entire spiral drive along the longitudinal axis of the vehicle, upwards or downwards, causes lifting or lowering of the vehicle relative to the ground FIG. 6, FIG. 7. Elongation of the driving spiral (1), FIG. 2 causes increased spacing between its coils, and the resulting increase in speed of the vehicle, or the ability to cross large rocks, stairs, or pulling of the vehicle up on obstacles. Maximum pulling in of the drive spiral (1) towards the operator (maximum shortening) allows to obtain a full roller, which allows for horizontal driving on even, asphalt surfaces with higher speed, similar to wheeled vehicles, or driving in sandy ground or quicksand.

(11) It is preferred that the spiral drive is multiplied FIG. 8 in order to increase traction, causing increased ability to overcome land obstacles, and increased maneuverability of the vehicle FIG. 9.
