Ecomobile

 

(57) Abstract:

The invention relates to environmentally friendly vehicles. Front and rear axle of the ecomobile is made in the form of a semi-elliptic leaf springs, which are fixed in the frame crossbars. At the ends of the front springs made boss with molded bushings in them, on which, by means of the removable axle mounted trunnion steered wheels on the ends of the rear springs - axis of the rear wheels. The trunnions are connected by cables that are located on both sides of their axes of rotation. One cable with two or three coils is connected with the steering roller shaft. The technical result is to reduce the weight and simplify the design of ecomobile. 9 Il.

The invention relates to environmentally friendly vehicles with a combo drive, and it is easy to muscle cars and electric drive.

From technical literature known to the pedal device of the vehicle (see kN. Dovydenas Century. And. "Velomobile" L. Mach., 1986, S. 96-97), consisting of a frame, front and rear axles, light hull-fairing and a pedal drive.

It is also known device easy crew with a combo drive (see kN. Popolo A. S. "From what I pedal or actuator from the solar battery and the auxiliary battery.

These devices are complicated and heavy. They have no automotive steering and no cushioning charms.

A prototype of the proposed invention is the device of a vehicle with transverse leaf springs and worm steering mechanism (see kN. Chudakov, E. A. "motor vehicle", M, Voenizdat, 1941, S. 387, 437-438).

The specified device has a semi-elliptic leaf spring mounted on the frame transversely and connected by their ends to the front axle, on which are located trunnion wheels. Axle, in addition, rods connected with the steering mechanism. The specified device has a heavy solid front axle, suspension parts leaf springs and rigid pushrods.

Such a device has a large mass, a complex structure, a large number of parts and components. These drawbacks reduce operational and technical properties of the vehicle.

The technical task of the invention is to reduce the weight and simplify the design of the car.

The mentioned technical problem is solved as follows. Ecomobile contains a body mounted on the frame, front and rear axle, driveshaft, steering the frame, moreover, at the ends of the front springs made boss with molded bushings in them, on which, by means of the removable axle mounted trunnion steered wheels at the ends of the rear - wheel axles, in addition, the trunnions are connected by cables that are located on both sides of their axes of rotation, and one cable to two or three coils is connected with the steering roller shaft.

In Fig.1 ecomobile is shown from the side.

In Fig.2 and 3 are a top view and a front view of ecomobile.

In Fig.4 and 5, the front spring is shown from the front and from above.

Fig 6 frame ecomobile is depicted in three projections.

In Fig.7 shows a cross-section of the power element of the frame (longitudinal and transverse).

In Fig. 8 frame with leaf springs (front and rear axles are depicted in space).

In Fig.9 shows a spring with swivel knuckle and steering.

Ecomobile consists of a body 1 fixed to the frame 2, which also fasten seat 3 and controls. The frame has a rectangular design and are made of spars 4 (longitudinal strength elements) and cross-beams 5. Power elements have a box-shaped frame (Fig.7) or U-shaped cross-section.

In the frame beneath the Cape of Sonnambula on the awning 7 on the hood and rear vertical surface of the awning are solar panels. With a total area of 2.5-2.7 m2.

To activate the battery and connect it to the solar cells and connections of the electric motor has an electronic control unit. Traction motor driver controls using pedal-accelerator (not shown).

In the variant muscle actuator on the frame of the ecomobile installed pedal 8, the drive sprocket 9 which circuit 10 is connected with the driven sprocket 11 of the drive wheel 12 tricycle through the intermediate sprocket 13.

The vehicle is made in the style of "retro", it has the footrest 14, the wings 15 of the front and rear 16 of the wheels.

Front and rear axle of the ecomobile is made in the form of a semi-elliptic leaf springs 17. A spring made of fiberglass (or carbon fiber) by hot molding. It can be made from titanium or from a pipe of square cross-section, of alloy steel.

Spring has ravnomereno section (Fig.4 and 5). It is designed so that at maximum load to ensure specified (maximum) stroke depreciation 70-90 mm

In the middle part (0.1 to 0.3 from its length) spring secured in the U-shaped duct (Fig. 7) poperechnyy frame using one or more (the information.

The front springs on the ends of the lugs 19 with pre-formed in their sleeves 20. On sleeves with removable axle 21 mounted trunnion 22 of the front wheels 23, which are mounted on welded to the pin axis 24 of the wheels.

The axis of the wheels 24, wheels, bearings, cones and nuts of fastening of wheels taken a standard Bicycle and motorbike type.

Boss preferovany to the spring with the provision of the angle of ejection axis of the wheels (8-10oand the camber angle of the wheels 10o. It is necessary for the stability of the movement of the vehicle and improve its manageability. The axis 21 of pins secured from the bottom with nuts controlkey or using washers and cotter pins.

Stubs performed levers 25, which through thimbles 26 connects the axle between the parallel cables 27. Cables to adjust their tension and wheel alignment are tender 28.

Rear cable two or three turns wound on the roller 29 of the shaft 30 of the steering wheel 31. The cable is fixed on the roller in the middle part from slipping on it.

The steering shaft is installed on the body and secured, in addition, on the frame of the ecomobile by means of brackets 32, with PTFE (plastic) bushings - bearings.

Rear spring instead Posadnik wheels.

Pedal drive wheels can be installed in front of the two front and two rear seats.

On the ecomobile installed electrical equipment required for vehicles of this class. On the hood with brackets installed lights 34, brake lights, marker lights and reflectors installed on the requirements of GOST. The audio signal, speedometer, control and measuring devices installed pursuant to rules and regulations.

The car has standard brakes. Bicycle brake sleeve, tick the hand brake on the rim and disc motorcycle brakes when installing alternative drive. Back up is provided by the reverse motor. When velodrive the pressure roller to the tire wheel (not shown).

The interior fittings and design body produced in accordance with the particular operating conditions (veloped, solar batteries, battery or alternative, gasoline, low-power engine). Depending on the specific operating conditions set the tent or closed body, put hard or canvas door and so on

The car is movable on the units and panels.

Isobune modern eco-cars, provides the advantages of this device over the prototype.

Ecomobile containing a body mounted on the frame, front and rear axle, drive, steering and wheels, wherein the front and rear axle made in the form of semi-elliptic leaf springs, which are fixed to the crossbars of the frame, and at the ends of the front springs made boss with molded bushings in them, on which, by means of the removable axle mounted trunnion steered wheels at the ends of the rear - wheel axles, in addition, the trunnions are connected by cables that are located on both sides of their axes of rotation, and one cable to two or three coils is connected with the steering roller shaft.
