The invention relates to the field of Bicycle transportation and can be used for transportation of goods.

A known design of a tricycle with one front wheel (and. with the USSR 1643305, class B 62 M 1/12, 1988) and two non-driven rear wheels. The front wheel is driven by means of levers. In this design there is a small compartment for the transport of goods, rear. This bike can haul freight only a relatively small weight and length.

A known design of a tricycle (U.S. patent N 4917396, class B 62 K 5/00, 1987) with two front irreducible wheels and drive the rear wheel. In this construction provides a container for transporting goods, located in front of the bike. However, this design does not allow you to carry long cargo.

A known design of a Bicycle with a side trailer, the complex represents a tricycle (patent Germany N 3915097, class B 62 K 5/02, 1981), which was the prototype of the present invention and containing a frame, a steering wheel, VerticalNet wheel, two rear wheels, the pedal actuator having a kinematic connection with the rear drive wheel containing overrunning clutch and chain transmission, brake system front and rear wheels, with a handle, cables and ticks.

This design of the bike can carry loads of relatively small weight and length, since the kinematic connection of the pedal drive with a drive wheel and braking system of the bike is not designed for riding with the weight of great weight and length. In addition, the center of weight of the structure does not provide stability.

The objective of the invention is the creation of a Bicycle for transportation of goods with more functionality by providing the ability to transport goods long length and heavy weight.

This is achieved by tricycle for cargo, containing a frame, a wheel, a vertical axis, which is installed with the possibility of rotation in a bearing unit, placed on a frame, front swivel wheel, two rear wheels, the pedal actuator, the brake system having the clamp and the handle, and a kinematic connection with overrunning clutch, is provided with an additional bearing unit, ball thrust and cranked the redstem kinematic relations, which introduced two elements. One of the elements made in the form of a double spherical articulated chetyrehzvennoy, consisting of a ring having a spherical outer surface and a cylindrical inner surface, spaced with a gap relative to each other, and the contact between any two adjacent rings is carried out by means of two diametrically spaced balls placed half in a single ring, half in another, and the other element is a multi-stage cylindrical gear with a common connection of the gears. The rear wheels are made with a diameter less than the diameter of the front wheel, and a set distance from each other greater than the transverse dimensions of the frame. The vertical axis of the steering wheel and the front wheels are spaced across the width of the bike, have the tabs and connected swivel thrust, forming together with the frame articulated four-link mechanism. Specified brake system wheels equipped with sliding bearings and Cams on the number of wheels, a beam and two shoulders lever with the brake pedal, located on one of the arms of the lever, the other shoulder which is connected to the middle of the beam, forming a kinematic pair of the ball-cylinder, and inside each of the slide in poperechnyy kinematic pair, in this slide the brake system of each of the rear wheels is connected with the corresponding end of the beam kinematic pair of the ball-cylinder, and slide the brake system of the front wheel is connected via a rod with lever brake system.

On the ends of the beam 34 is made spherical protrusions 68, arranged without a gap in the cylindrical holes 70 slide 71 mounted for movement in a vertical direction in the guides 72, mounted on the beam 3.

In the slots 73 /Fig. 7/ slide 71 mounted for movement in a direction perpendicular to a reasonably possible movement of the slider 71, the Cams 74, made in the form of discs. With each of the Cam disc 74 in contact rollers 75, mounted for rotation on axes 76, mounted on one of the two shoulders shoulders RA other shoulder every two shoulders of the lever 77 is fixed brake pad 79, placed on the periphery of the hub 68. Describes the sliders 71, disks 74 and two shoulders levers 77 are components of Cam mechanisms contained in the brake system for the rear wheels. A similar Cam mechanism exists in the brake system for the front wheels.

Full brake system for the rear wheels comprises two shoulders lever 7 /Fig. 8/ with the brake pedal 31, the beam 3, the sliders 71, Cams discs 74, two shoulders levers 77 with the brake pads 79.

There are mechanisms tricycle as follows.

The Bicycle's movement begins after the effort of the driver to the pedal 10 foot drive. When this torque from the driving gear 17 is transmitted through the driven gears 18, 19 and one of the gears 20, 21 one of the gears 22, 23 of the rolling block, and therefore the shaft 35, the housing 52 overrunning clutch 36, the rings of the double spherical articulated chetyrehzvennoy 37 and, finally, the front wheel 16.

Gear by moving the gear train 22, 23 along the shaft 35 of the lever 49 gear.

The rotation of the front wheel 16 is made by turning the steering wheel through an articulated chetyrehzvennoj, consisting of a frame 1, h is to transmit torque from the pedal drive. The second spherical articulating chetyrehzvennoj 60 compensates for inaccuracies installation of the shaft 35 with respect to the axis 40 of the front wheel 16.

The overrunning clutch 36 is slipping dogs 51 with respect to the grooves 63 only during rotation of the wheel 16 with a greater angular velocity than the angular velocity of the shaft 35 created by the driver.

The braking of the front wheel 16 by turning the handle /not shown/, which through rod 62 moves the slider /not marked/ Cam mechanism, the brake pads which create a braking torque on the outer surface of the ratchet wheel 53.

When braking the rear wheels, the force created by the driver on the pedal 31 is transmitted to the middle of the beams 34, and further to the sliders 71 of Cam mechanisms. The sliders 71 through the disks 74 affect the rollers 75 two shoulders of the levers 77, which with brake pads 79 create a braking torque on the hub 68 of the rear wheels 7.
