Abstract

Device for tilting three-and multi wheels vehicles to offset the centrifugal and gravitational forces are made up of a control rod (14) pivotally stored in the bed (28), generating torque that is transferred through the lever (27) the structure of the front axle (A ), where there is a pair of zigzag transformed moments M1 = F1 x D1 and M2 = F1 x D2 respect to a fixed point in taking a moment M1 is larger than M2, which causes the regulated heel structure of the vehicle.

Description

Technical field

The technical solution relates to three-wheel and multi-wheel trucks with tilting to balance centrifugal and gravitational forces.

BACKGROUND OF THE INVENTION

Until now, tilting lightweight trolleys and multi-wheeled trolleys has not been widely used. The reason was the cost of installing balancing systems, which too often required complex systems. Slowly moving tricycles did not need balancing devices because the centrifugal and gravitational tilt forces were not great and therefore their disadvantages were tolerated. As the speed increased, there was a danger of overturning around the side wheel linkage, as well as an uncomfortable pull on the outside of the bend. Lowering and moving the center of gravity of the truck has not always been structurally advantageous and has been only a partial solution. For this reason, tricycles and other carts remained condemned to instability, slow driving and tolerance of the discomfort of transverse thrust.

The essence of the technical solution

These deficiencies are largely eliminated by the device for tilting three- and multi-wheeled trolleys. The essence of this solution is that the tilt as a function of the bend radius as well as the speed of the tricycle are manually controlled by the rider of the tricycle and determined as in a bicycle with a natural sense of the required heeling. Both radius and velocity parameters are simultaneously controlled from one location and fixed to the momentary value at which the centrifugal and gravitational forces balance is achieved and thus safe driving at increased speeds.

An overview of the pictures has a drawing.

Fig. 1. is a general view of the tricycle; Fig. 2 shows the kinetics of tilt.

Examples of technical solution.

The tricycle of FIG. 1. is composed of a front axle (A), a frame (B), a tilting mechanism (0) and a rudder mechanism (D).

The front axle (A) is formed by a left hub 1 with a fork 30, a central hub 3 and a right hub 2 with a fork 31, wherein 1, 2, and 3 are rotatably connected to each other by a rod 4 and a rod 5. The points (a), (b), (c) are connected by tension springs 19.

The frame B consists of a structure 21, fixed to the center hub 3 of the front axle ZA / by means of the pivot elements 23 and 23A and the stiffeners 29. Mounted on the frame: rear fork 25, seat 8 and foot support 7. The drive unit 32 is connected by a chain to the rear wheel 15.

The tilting mechanism (CZ) consists of a control rod 14 rotatably mounted in a bearing 28. Vertical oscillations of the rod 18 are transmitted via a spherical joint 18 to a rod 26 which is connected via a spherical joint 18A. and further to a pivot lever 27, which is pivotally mounted at the hinge 34 and is connected thereafter to the upper part of the front axle (A). The locking mechanism 13 has an open position or a pivot blocking position of the rod 14 and is located between the shaft 24 and the control rod 14. This function comes in handy during insertion and removal.

The tilting of the tricycle and multiple wheelchairs can also be accomplished by means of a servomotor connected to the pivot lever 27 and connected to a data processor: the acceleration sensor, the speed sensor, the steering sensor and the feedback sensor produce the necessary tilt sizes.

The rudder mechanism D consists of a central hub 3 in which a rotatably mounted shaft 24 is attached at one end to a rod 14 and at the other end to a pivoting member 9 slidably rotatably connected to a pin 32 of the rod 11. rotatably mounted in the members 10 and 12 of the forks 30 and 31. The forks 30 and 31 are also rotatable wheels 16 and 17.

Fig. 2 shows a schematic tilt of the tricycle at an angle (Beta) determined directly by the rider by pressing the rod 14 from position (a.) to position (b), wherein the parallelogram formed by elements 1, 2, 3, 4 and 5 is collapsed to an appropriate tilt. This tilt angle of the whole vehicle is held by the rider according to the situation of speed and cornering radius.

... The torque generated between the shaft 14 and the shaft 24 is transmitted via the lever 27 to the front axle structure (A) in which a pair of counter-torques M1 = F1 x d1 and M2 = F1 x d2 with respect to the fixed point U is generated. M1 is greater than M2, which causes a regulated tilt of the vehicle structure.

The 'U' reference points consist of the touch points of the three wheels 15, 16 and 17 on the ground, the points which are the fixed kinetic base of the tilting device.

The tilting of the tricycle and multiple wheelchairs can also be performed by a servomotor connected to the pivot lever 27 and coupled to a processor which of the data: acceleration sensor, speed sensor, steering sensor and tilt feedback sensor, generates a control signal for the servomotor.

The connecting rods 4 and 5 of the parallelogram can also be guided through its lower part and thus free up more space for the rider's legs.

Two-piece lightweight cover around the entire tricycle and powered by a 1a1 / 2 KW engine with lithium-ion battery, can make this one-way tiltable tricycle or quad bike a versatile vehicle for every day.
