Description

The invention relates to the field of engineering, in particular the automotive industry.

Currently, the most common electric vehicles running on batteries. Magazine "Inventor and Rationalizer", 1999-2001.

Batteries are bulky, heavy, require a lot of time to recharge. Expensive in price.

And at the same time, the mileage of such an electric car is very small.

There are electric vehicle options that run on solar panels, but they are complex, expensive and far from perfect.

The purpose of the invention: the construction of a cheap, easy to manufacture and operate all-weather, all-terrain electric vehicle.

To do this, on the suspension of an electric vehicle (dependent, independent), as on its most movable part, we install vertically a lever that is movably connected to the lever on the body, as on the most inactive part of the electric car. The lever on the body is mounted horizontally by means of a hinge, and a smaller part of it from the hinge is connected to a vertical lever mounted on the suspension.

The distance between the hinge of fastening the horizontal lever with the vertical lever varies depending on the speed of movement.

At the end of the long part of the lever mounted horizontally on the body with a hinge, a gear rack is installed having a Z-shaped profile.

The teeth on the rail are cut from both sides, in width.

Toothed gears are adjacent to the rack, one directly, the other through an intermediate gear.

The gears are connected by a shaft to the gearbox, through it - to the electric generator, which is connected to the battery.

Figure 1 presents schematically the design of the drive generator of an electric vehicle.

Figure 2 shows the location of the gears on the sides of the gear rack with a Z-shaped profile and their relationship with the generator.

Figure 3 is a side view of the location of a single gear on one side of the drive rail.

Figure 4 is a side view of the gear associated with the other side of the rack through an intermediate gear.

In Fig.5 - the location of the gears in the cross section of the rack.

The movement of the gravitational electric vehicle is as follows.

At the beginning of the movement, a battery is connected before the traffic light or after a stop - the electric power is supplied to the electric motors, the car moves.

In motion with roughnesses on the road, the suspension 1 with the wheel 2 is displaced up and down relative to the body 3, which also oscillates relative to the roadbed and naturally relative to the suspension.

When the suspension is shifted upward - closer to the body of the electric vehicle, the vertical lever 4, mounted on the suspension 1, also moves upward to the body and lifts one end of the horizontal lever 5, its smaller part, to the hinge 6, most of the lever from the hinge with gear rack 7 goes down .

The gear rack 7, moving downward, rotates the gear 8 connected to the gearbox 9, and rotates the electric generator 10. The second gear 11, adjacent to the other side of the gear rack 7 in width, rotates idle through the intermediate gear 12, since both gears connected to the gearbox , have one-sided gearing with a shaft and work only in one direction.

When lowering the suspension, the vertical lever mounted on it, falls down and pulls the end of the horizontal lever, hinged to the body. The other end of the horizontal arm, together with the gear rack, rises up.

In this case, the gear 11 through the intermediate gear 12 rotates in the same direction as the first 8 when lifting the suspension, and transfers its rotation through the gearbox to the generator.

The generated electricity is used to recharge the battery 13.

The first gear 8, which works when lifting the suspension, rotates idle in the opposite direction, since the gearing with the shaft is one-way.

When the electric vehicle sets the appropriate speed, the vertical lever attached to the suspension and to the horizontal lever is shifted to the hinge 6, the lever action shoulder decreases, and since the gearbox and the electric generator along with it are already accelerated and have gained speed, decreasing the lever arm of the vertical lever increases accordingly speed and amplitude of displacement of a gear rack, gearbox, electric generator. Electricity generation is increasing.

So when the electric vehicle is moving, its suspension, meeting with irregularities of the roadbed, is shifted up and down and by means of levers the gear rack 7 is moved up and down, which rotates the electric generator by means of gears and a reducer. The electric generator constantly feeds batteries.

Claims (1)

An electric vehicle comprising a body, batteries, wheels, a generator with a drive including a pivotally mounted two-arm lever, one shoulder of which is connected to the axis of the wheels, and the other kinematically with a generator, characterized in that it is capable of converting the vertical displacement of the second shoulder into one-way rotational by means of a gear rack with a Z-shaped profile located at the end of this shoulder, and a pair of gears having unilateral gearing, one of which is adjacent to the rack directly, and the other I - via an intermediate gear.
