“HOPE” – A RECUMBENT WITH COMFORT

“M-K” can rightfully be considered one of the founders of velomobiles in the country: in its pages appeared in 1976, the description of the first, still largely imperfect muskurahat Vita. Remember! And folding ludikar “Hummingbird”! For 15 pet journal also regularly acquaints its readers with the most interesting diys.

Today we offer to your attention another option — recumbent “Hope”, created by V. KRASNOV from Kolomna. His appearance, in our opinion, begins a new milestone in the development of this mode of transport. High ergonomic performance, good aerodynamics combined with the rational kinematic scheme, modern design differentiate this car.
 
Travel allow people to see the world, the country, to know its edge. Each “knight-errant” selects the transport that best meets their goals, needs and opportunities. Stories seasoned veloturistov prove conclusively that a pedal vehicle in most cases is almost perfectly suited for long journeys. It allows you to travel in comfortable conditions in any weather, carry a big load without causing excessive fatigue of the driver, and sometimes to serve as a bed on a sleepover or a means of crossing a small water obstacles. At the same time, he, like a normal bike, it helps to experience and to know themselves, to assert themselves, to test the capabilities of your body.
For several years in our country, meetings are held competitions-veloturistov. One of its stages is run on the Golden ring of Russia. For this track and was designed and built recumbent “Hope”. Hope for their strength, design, reliability are the main factors that gave the name.
 
The recumbent is carrying, fully enclosed plywood box with a flip-up and down the hood. Manufacturing technology is borrowed from the methods of building small boats from plywood: using wire twists and the subsequent taping of the seams with strips of fiberglass.

We should start with a scan to cut out the bottoms, wheel arches and sides. The contour of the workpieces drilled holes 1 0 mm in increments of 30…40 mm. and Then to the bottom wire twisting “sewn” side and wheel arch. After a fixation time of inserts and spacers and alignment possible deformation of the body will need to glue the seams to the inside of the fabric on the glue and epoxy. If you used “epoxy” to glue necessarily should be in a well ventilated area.
 
The next stage is the connection of the roof and the rear part with the “fit” of their place. If after that, the body appearance and the design you would like, you can gently, with a sufficient allowance, and cut the top a skylight, and then to glue all the seams from the inside. The number of layers ranges from 3 to 6. After completion of the work inside the body should be removed with pliers the ends of the twist and bend excess wire along the seams.
 
External works consist of small round corners on the joints of panels and pasting the entire body with a thin fabric in a single layer. After complete drying or polymerization of the resin, it is possible to cut window openings and a removable hood. The contour pasted the necessary support and strengthen the cap.
 
Glass body made of organic glass with a thickness of 1,5 mm. Glass glue epoxy glue.
 
Suspension. Used wheels from a Bicycle “Desna” and “Eaglet”. Front applied without alterations, and in the back for gain had to increase the number of spokes. All-wheel drive closed fabric caps-cones that improve aerodynamics and its external appearance.
The velomobile is equipped with soft-spring suspension front and rear axles. The front axle consists of a double beam-pipe, which are fixed lugs swivel axles and pad guides for travel of the beam in the vertical direction on the rod bolts. The springs are selected from the valve mechanisms for engines of passenger cars. To enable the warp beam to the underbody when driving on uneven lower covers have holes for the guide rods with a diameter of 0.7 mm larger than the diameter of the stock.
 
The tie rod with the adjusting elements of the toe are located in front of the beam. The rotation of the steering wheel is transmitted via the bipod and extra traction length 180 mm on the tie-line through the hinges with nylon bushings. The gear ratio of the steering mechanism 1:2. The maximum steering angle to 30° to accommodate the turning radius of the car is 3.5 meters.
 
Rear axle consists of a block of stars with number of teeth 11, 14, 17, 20 and 24. It is connected through the makeshift one-way clutch with the shaft of the right rear wheel. The whole mechanism revolves inside the beam rear axle bearings. Brake — cable, on both of the drum from one handle. The left wheel rotates freely on the axis. Depreciation of the rear axle done using three longitudinal levers and two springs from the seat of a motorcycle “Minsk” first releases. Springs attached to the ends of the side levers, and axle offset 100 mm forward from them. This is done to increase suspension stiffness. The Central lever is designed to reduce the deflection of the bridge under the action of a stretched chain.
 
Coaches face-to-face site — homemade, has two asterisks with the number of teeth respectively 56 and 48. Transfer circuit is a switch from a sports bike.
 
Gear change transmission driven sprocket fixed to the casing of the unit and consists of two plates of the cheeks, two rollers, axis, return springs,
 
three brackets and pull cable.
 
The device is similar to the soup port sport bike. The total number of gear recumbent is 10, so it is possible to choose the most appropriate for any road.
 
Seat — semi-rigid. The frame is assembled from pipes from the cot and plywood plates laminated foam with a thickness of 30…40 mm. from the Top seat is sheathed with a cover of “loose” fabric.
 
Because the velomobile is moving In the Potts-ke cars, it must be equipped with turn indicators and a system of “vallecrosia”. You must also have a rear view mirror and, preferably, velometer, which can be conveniently mounted on the alcove of one of the front wheels. Security working and bright, conspicuous colour of the body: the “Hope” it’s yellow.
 
Travel along the body set two large bags to camping accessories and products. First aid kit and repair kit with some located in the forward trunk.
 
Conditions for velomobiles are closed body, good: whatever the weather glass does not mist, and the air circulation is satisfactory due to directed flow of air from the cracks of the intakes.
 
If desired, the velomobile can float if sealed front axle beam rubber cuffs seals in wheel wells. To move water or using double bladed paddles, or blades, combs, attached to the rear wheels.
 
First trip of “Nadezhda” took place in February 1990. He confirmed that the design is convenient, easy, fast, adapted to the many hours of travel.
 
A few words about yourself. Are velomobiles since 1986. Made the two devices. My firstborn — recumbent “Kokra” — was shown in 198В year at the festival “Golden ring” and was awarded a diploma.
