Abstract

Device for movement on the ground included two four-wheel axles (A) and (B), carrying frame (3), backing rod (10), rudder (C) and braking (D) mechanism. The axles (A) and (B) are connected with carrying frame (3) trough the central bearing (2) joined to rudder mechanism (C) which is connected to the swivelling arm (4), the arm is attached over the hinge (11) on the frame (3). Backing rod (10) allows to a rider the stability during acceleration, breaking, and on the corner. The breaking mechanism (D) has action on all wheels equally and synchronize and is centrally directed from the rode (4) though the breaking lever (18).

Technology / λχΛχ /

The technical solution relates to a vehicle for y terrain movement.

BACKGROUND OF THE INVENTION

So far well known so-called. "Skateboards" are mainly used on flat surfaces. There are also "skateboards" designed for the terrain, which have larger wheels, but in principle have the same design as classic "skateboards". These suffer from poor handling and driveability such as rider stability, high ground sensitivity and problematic braking.

The essence of the technical solution /Τ'.χΛ/

The above-mentioned drawbacks are largely eliminated by the pfe field movement, which consists of two four-wheel axles from the support frame, the steering rod support rod and the braking mechanism; The axles are connected to the support frame via a rudder mechanism, and via a spring-loaded pivot arm which is connected via a pivot joint to the support frame.

The essence of the device is that the axles are pivotable in the forward-rear direction. allowing axles to track terrain unevenness that is not transmitted directly to the rider. In addition, each axle is independently suspended from the support frame, ensuring comfortable driving, despite rough terrain. The associated rudder mechanism allows the axles to pivot in the appropriate direction when the load frame is suspended laterally.

Another principle is that the device has a rigid support rod connected to the support frame, which provides the rider with stability during acceleration, braking and twisting when balancing centrifugal and gravitational forces. A brake lever is also attached to the support rod and its arm.

Another principle is the braking mechanism which allows braking of all eight axle wheels simultaneously and evenly. The brake mechanism is operated centrally from the brake lever located on the support rod.

The off-road bend provides a safe and comfortable ride in the wild and can also be used on ski lifts during the summer.

Examples of technical solution

The off-road movement device consists of two four-wheeled axles aJB, a supporting frame, a. and the steering gear rod 10 and the braking mechanism D, characterized in that the axles A and J are connected to the support frame 3 via a central bearing 2 which is connected to a steering gear C which is connected to a spring-loaded swinging arm 4 which is connected via the swivel joint J1 to the support frame J.

Each of the axles A or B is composed of a bogie 1 on which four pneumatic wheels 9 are rotatably mounted. A central bearing 2 is also mounted on the chassis, allowing the front and rear swing of the axles to adjust the axles to uneven terrain.

Independent suspension of the axles A and B with respect to the frame 3 is effected by means of a spring 25 located between the pivot arm 4a of the frame 3, wherein the arm 4 is attached to the frame J via a swivel joint VL

At one end of the support frame, a fixed support rod 10 terminates with an support arm 16 and a brake lever 18. For storage and transport of the device, the support rod 10 can be folded by a hinge 20 and stiffeners 2-3 and its length can be adjusted by telescopic arrangement. The seat bar is a stabilizing element for the rider during acceleration, braking and curves.

Rudder assembly. It is formed of an inclined bearing 6, a shaft 7, a washer and an elastic element. The shaft 7 is connected to the bearing 2 and also to the elastic element

8. The rudder assembly C as a whole is then mounted on the spring-loaded swing arm 4. The lateral tilt of the frame 3 with the plate 17 causes the inclined bearing to swivel around the longitudinal axis as well as the vertical axis, causing horizontal rotation of axles A and B. it is a spring-loaded tilting and swiveling in both directions by means of the elastic element JT

The same steering result is achieved by replacing the inclined bearing with one longitudinal bearing rotating the frame about the longitudinal axis and one vertical bearing. * · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · A bearing turning the axles _Aa_B around a vertical axis. Swiveling about the vertical and longitudinal axes in both directions is spring-loaded.

Both constructive solutions can be applied without changing the nature and principle of steering. The sloping floor plate slider .17 on one side or the other causes the axles A and Bi to turn in the appropriate direction.

The braking mechanism consists of brake elements 15 pivotally mounted in the articulated joints 21 on the axles 21a of the cable system, centrally operated by the brake lever 18. Each brake element has a brake shoe located on one side opposite the wheel disc 9. The other end of the braking element is comforted roller 13. Element J5 is pulled away from the wheel rim j) by the spring 30 through the pulley 13 is driven cable system 26 shown in Figure 2 to fork rollers _22? The cable 28 is connected via a fixed terminal 19 to a cable 23 which is connected to a brake lever 18. located on the support rod 10 with the arm 16 .. By means of the cable system shown in FIG. 2, it is possible for all wheels of both axles to brake simultaneously and evenly.

The stability of the rider is maintained by the support rod 10. The centrally controlled braking mechanism ensures safe braking of all wheels 9 of axles 17A and 16B evenly, which is particularly important for nature conservation, (plucking grass and vegetation). The four wheel swivel axles A and B and their independent suspension give the rider a comfortable and safe ride even on rough terrain.

. The off-road equipment is specially used on ski lifts during the summer season, with the machine itself being pulled through a safety rope by a ski lift.
