The invention relates to multiwheel vehicles with a muscular drive containing the reciprocating moving the foot levers and platforms for oscillatory motion around a horizontal axis.

Currently, the development of vehicles with a muscular drive aimed at finding new directions, allowing you to put more emphasis on human capabilities, by improving the efficiency of muscular drive.

Known vehicle equipped with streamlined cabins: EP 0035134 disclosed multiwheel vehicle equipped with a conventional crank drive with the location of the person lying down or standing up. In the US 4779485 disclosed such a slick tool with a recumbent location of the person. This means abandoning pedaling provided by the reciprocating moving of the foot levers. The efficiency of the drive further enhanced by the fact that the drive shaft installed in the housing of the inertial battery with the clutch switching and variable.

Another way is to refuse pedaling in the process of energy transfer and its replacement by a transformation walk into rotational motion. Famous bikes, containing levers with hinges, which allow moving the legs of a man with legs to bend and straighten knees (US 3881747 US 2007037667). However, in these rental contains a saddle that does not allow full use of walking opportunities to improve the efficiency of the drive. The arms in these bikes have only one hinge, which in the case of US 3881747 does not allow you to omit the drive shaft low enough, and in the case of US 2007037667 requires a sophisticated drive because of the need for inclusion in the drive intermediate circuit. Also inventions in this area include vehicle: SU 1769750, EN 93011408, EN 93011387, EN 94007879.

The aim of the present invention is to improve the efficient use of energy while moving in a vehicle that transforms walking into rotational motion.

The prototype of the selected vehicle, disclosed in RU94007879. This vehicle includes a frame, wheels, some of which made manageable drive from swinging when walking legs and arms hanging over the star wheels on the transverse drive shaft, transmission with a leading asterisk, connected by a chain driven sprocket mounted on the shaft of drive wheels. It successfully solves the problem of increasing the functionality of man by converting walk into rotational motion. However, this vehicle has the following disadvantages:

a) large aerodynamic resistance PR is moving; the lack of comfort due to the insecurity of the person from climatic conditions;

b) when changing the profile path or other causes additional resistance to the wheels of the vehicle, these changes require changes in power when driving, that adversely affects the engine - man, accelerating fatigue that reduces the range of users (age, health, and others);

in) "Shagane" the man with the supports at a constant radius levers is walking on "closed" legs that affects the ergonomics of the vehicle and as a consequence reduces the functionality of the person.

To reduce the aerodynamic resistance of the air and increase human comfort drive shaft is lowered significantly lower due to the inclusion of the upper hinge arm, hanging on the ratchet, and means provided with a transparent cabin laminirovannogo profile, providing a minimum air resistance. The above technical result is achieved in a vehicle that includes a frame, wheels, some of which made manageable drive from swinging when walking legs and arms hanging over the star wheels on the transverse drive shaft, transmission with a leading asterisk, connected by a chain driven sprocket mounted to Nabal wheels. Rocker arms are made with top and bottom hinges. The bottom hinges enable when you move a person's feet with legs to bend and straighten the knees. Reducing the air resistance is provided by the upper hinge, enabling to omit the transverse drive shaft, and through the transparent cabin, providing the minimum resistance of the air.

The drawing shows a vehicle.

The vehicle contains a transparent cabin (1) with the door (23), a frame (14), the main drive wheels (10), provided with overrunning clutches, and support (18), made manageable.

The actuator consists of two supports (16) to install the man fixed on the swinging arm (7), which are made with hinges (15) and (24) (allowing for the movement of a person's legs with supports to increase torque), suspended through the star wheels (6) on the transverse shaft (3)mounted on bearings (4) uprights (13)rigidly connected to the frame; inertial battery (19); transmission with a leading asterisk (or CVT) (2), connected by a chain (5) guest the asterisk (8)installed on the shaft of drive wheels (10). This sprocket mounted on the transverse shaft and the shaft rotates in bearings fixed and protected by a casing (12).

The vehicle is driven people who ECOM, walking together with attached to the legs of the supports (16), which make the Shuttle movement about the axis of the shaft (3)with which they are associated through the star wheels (6). When this shaft carries out a rotational movement, passing it through asterisks (2, 8) and chain (5) to the drive wheels (10), resulting in moves and all means of transport.

Control and braking is performed by means of a system of levers (20)connecting the front wheels of the vehicle steering wheel (21)mounted on the rack with hinge (17), which removed the handle of the brake (22).

There are also limiting movement of the supports (11), which can be performed with magnetic plates, and a folding seat (9), and hour of the steering wheel provided with a hinge (17).

The vehicle containing the frame, wheels, some of which made manageable drive from swinging when walking supports (16) and the levers (7), suspended through the star wheels (6) on the transverse drive shaft (3), the transmission from the leading sprocket connected by a chain driven sprocket mounted on the shaft of the wheels, characterized in that the rocker arms (7) is made with the top and bottom hinges (15, 24), the lower hinges (15) give the possibility of moving the feet of the man with the supports (16) to bend and straighten the knees and lowering the resistance of air is provided through the m upper hinge (24), giving the ability to omit the transverse drive shaft (3), and through transparent cabin (1), providing a minimum air resistance.
