The desire to ski “with the wind” makes us resourceful athletes to invent a new sport: racing on skis towed behind a motorcycle (skijoring), boat and even horse. Today, it seems we are on the verge of “opening” another form of skiing-a tow sport where the athlete has to match the skills of the skier with the ability to manage a sailboat on the tires with very low pressure. Such towing is already popular among fans of winter tourism, as they allow us to travel long distances without special effort on the part of the athlete.
A sailing ship is a two-wheeled cart with a couple of light tires with very low pressure
and rigging type “Bermuda sloop”, that is, equipped with two sails — a mainsail and a jib. This type of weapons allows the tug to go cool enough to the wind, which is very important when running downwind in open spaces when you have to move towards the wind. Windage ^ towing is about 7.5 m2, which allows the skier to move even with moderate wind.
Frame sailboat is a cruciform structure, welded of steel thin-walled pipes with a diameter of 50 mm. Connecting longitudinal (longitudinal) and transverse (- axis) of the beams is carried out using a diamond-shaped gusset plate and joint-braces of steel sheet of thickness 2 mm In the axis has two axles, fixed so-called plug lap joint.
Wheel of the sailboat are welded from steel tubes with a diameter of 12…16 mm. Before dealing with their production, we should clarify what tires are you going to “Shoe” your wheels, and to align the sizes of openwork disks with geometric parameters of the rubber cameras. The wheel consists of a welded together of the sleeve (cut steel pipe) and steel ring. After welding in the bushing chiseled the holes for the bearings n 204. For welding the hub and the rim, it is desirable to construct the simplest slipway, which will enable you to centrovite these details.
