(57) Abstract:

The tricycle is designed to move using the muscular force of the person. Levers tricycle made foot platforms along the entire length to move around the driver. They are connected to the rocker arm through the connecting rods and the rear ends through the sleeve with the axis of the rear wheels and with the planetary gear. The result is improved efficiency of the recumbent. 12 Il.

The invention relates to the field of engineering, namely, devices for actuating vehicles muscular force of the person, such as pedal cars, bicycles.

A known design of a Bicycle [1], with the front wheel, saddle, right and left drive levers with pedals on one end of the levers and the device is put in action, made in a single kinematic chain with overrunning clutch, the leading elements which are connected with the actuating levers, and a common driven element overrunning made in one piece with a part of the carrier, on which is rigidly fixed to the leading gear and through it, mounted on the axis, is rigidly connected with the housing, is connected with the crown gear, associated with gear trevenzuolo engagement with the driven gears of the transmission torque and placed on top of the sleeve, which is also the leading element overrunning clutch, a driven element of which is the hub of the drive wheel, and a longitudinal groove leading sleeve is the exhaust mechanism of the pins connected to the gear shift mounted on the steering wheel of the vehicle.

The disadvantages of this design are that in this invention is an attempt to replace three gears the natural ability of a person to change in a wide range of speed, thrust and speed; the discrepancy of the declared number of revolutions at full cycle of pedaling; high on-axis thrust gear.

Closest to the present invention is recumbent, containing the driving and the driven wheel, steering with the palm rest stops for the legs, seat lever mechanism for converting reciprocating motion into rotational drive to the drive wheel, characterized in that to increase efficiency by stepless variation of torque during continuous rotation of the wheels of his drive made in the form of two symmetrical ball screw pairs associated with the axes leading to the TKA, with the possibility of axial and rotational movement relative to the nut [2].

The disadvantage of the prototype are the loss of up to 50% efficiency because of the diagonal decomposition forces the levers on the components. The efficiency loss due to the rotation, based on the friction of the carriage about the axis of the wheels. The constant swing of the head of the driver to 40%, which obstruct the view of the road and is not natural to man. The absence of a declared variable changes of torque.

The purpose of this invention is: an extremely full use of the weight of the driver, cargo and muscle strength of the arms, legs, back turning them into traction force in natural human complex, accessible to people of all sizes and age-related changes; the manufacturer under the terms of the customer drive with any gear ratio, high efficiency and durability of the mechanism with the distribution of the main friction on the details in an oil bath with forced feed lubrication; a smooth change in the amplitude of the vertical reciprocating motion of the legs associated with changes in thrust at a steady speed for energy saving; full loads are removed from the frame and front wheel to improve the runnability of the machine and avoid burying the front wheel; the exception inefficient zones in the active grinding and storage.

This goal is achieved entirely by the fact that in a motor tricycle, comprising a front wheel, the steering wheel to control the frame with two rear wheels rigidly located on the same axis, the right and left drive lever and the drive is different from analogues and the prototype in that the levers are made along the entire length of both pedals, giving the driver the ability to move them with the aim of continuous change of the amplitude and speed of the vertical reciprocating motion of the legs, traction control, with a sustained speed of velomobile with influence over the levers on the teeth of the movable crown gear, located on the axis of the wheel and a transfer case driven by the internal teeth of the crown gear and containing not having fixed axes of the four satellites, four intermediate satellite, the driven sun gear mounted on the spline axles, drive in the liquid oil bath with forced feed lubrication, transportation of domestic cargo, fixed rear on the driver is not above the top of the pelvic bone that meets the criterion of "novelty."

Passenger tricycle includes a front follower wheel 1, a frame 2 and two rear driving wheels 3 arranged rigidly on the same axis 4 connected to the frame 2 through the crankcase 5 by welding, and the bearing-sleeve 6, the wheel 7, the Parking brake 8. The actuating levers 9 left and right, each of which along the entire length has a foot platform 10, in the middle is connected by a rod 11 through the arm 12 and the rear end through a sleeve connected to the axle of the rear wheels 4. On the rear end of the levers with the specified shoulder ratio pivotally mounted four spring-loaded pawl 13 included in a one-sided engagement with the external helical teeth of the crown gear 14, through which the sleeve and inserts located on the common axis of the rear wheels 4. Crown gear 14 connected to the internal straight teeth with four Setaria intermediate satellites 16. Intermediate satellites 16 are connected by straight teeth with a sun gear 17 that is associated with the axis 4 splined connection. The actuator is closed crankcase 5, which is filled with a mixture of the gearbox with grease before contact with the satellite gear 15. All stellites on all axes have the ball bearing 18 and through balls and teeth rest against and slide in the crown gear 14, which is the housing of the transmission. Assembled on the side of the node transmission is mounted through the inspection hatch 19 Carter, the edges are placed on the axis 4 levers with foot platforms 9 and sides clamped planted on the splints sleeves 20. The crankcase 5 is mounted on the axle 4 through bearings with seals. Between the rear wheels and Carter on the axis 4 are fastened rigidly brake discs 21, tighten the nuts with a plate 22 fixed to the crankcase through the cable-brake 8. Front and side panels of the crankcase are more durable. Sustainable vertical Parking position is provided by attached to the crankcase of the sheath 23. The wheel is mounted hinge bolt 24 and a removable bolt 25. Inspection hatch is attached through a spacer bolts in the front top half of the crankcase.

Passenger tricycle works as follows.

Putting on thigh pedicel includes its weight in its own. This position of the cargo does not cause drifts of the driver when turning the hull and review of road conditions. Getting up on the front end of the foot platform 10 from entering the wheel, the driver passes the maximum thrust, losing in the physiological abilities of the person as quickly as possible to make the vertical reciprocating motion of the feet due to the large amplitude and high energy consumption. Therefore, pedaling in front of the pedals corresponds to the beginning of the movement and climbing uphill. On roads with a small bias driver departs ago, which corresponds to the inertial influence of the length of the platform-pedals - 0,8 m From the end of the pedal platform driver physiologically capable of many times the speed of the reciprocating movement, keeping the amplitude of their movements completely, which corresponds to a high speed tricycle, while losing in the applied force due to the reduction of the length of its application to the lever. This thrust force via the spring-loaded one-way pawl 13 is transmitted to the external oblique teeth of the crown gear 14. Crown gear internal teeth 14 rotates four satellites 15 through a small gear and a large gear these satellites rotate four promo seated on her wheel. Passenger tricycle moves. Satellites 15 and 16 form a locked element of the planetary gear excluding scrolls own opposite rotation. All transfer, revolving around the rear axle, satellites crown gear 15 captures in the crankcase lubricant and, lifting, distributes it to all rubbing parts of the drive. Pedal lift each other through the connecting rods 11 and a yoke 12 with limiter. The wheel is formed in the hinge 24 by removing the bolt 25.
