The invention relates to bicycles, specifically to cargo bikes.Known for the rental of two - and three-Wheeler, with chain drive to the drive system, the design of which includes an additional frame elements, designed for the installation of the body, trunk or trailer. These bikes are having in principle a good margin of safety and capacity, however, are limited in their very limited.The problem to which this invention is directed, is to improve the functionality of the cargo bike, to increase its capacity and efficiency respectively. This goal can be achieved in the case of the actuator bike two systems of lever mechanism (in addition to the basic levers-cranks connected with the leading asterisk), the first of which carries out the function of transmission, converting the circular motion transmitting torque of the cranks in movement in an elliptical path bred outside their axial system of rotation of the points of application of force, and the second increases attached to these points force the cyclist.Known designs of bikes that use a lever mechanism for transmitting muscular effort on the wheel (patents France N 2745783, N 2713585, N 2487281, N 2480700; the patent of Russia No. 1803342 A1; patent USSR N 1785675 A1; patent EP N 0471640 A1 and others). However, since the use cases articulated linkage relate only to the construction of road and sport bikes, the prototype of the invention, it would be better to take the design of the articulated linkage, provide (patent PCT WO 96/26103).The invention of the prototype is the transmission mechanism for bicycles and other types of machines presented in the form of two levers with mobile terminals associated with the crank mechanism hinges and have a sliding (on a common shaft) stops. The aim of the invention of the prototype is to achieve a torque within one revolution of each of the crank due to the increase attached to the force transmission due to the use in the drive system of levers.The main drawback of the invention of the prototype is its abstract and schematic in nature, are not supported with any design solution.Second: rod levers are floating stops at various points appearing at different distances from the point of application of force, making them the most effective use is not possible due to the need for the rider to overcome the too great length of the legs when the variance of the levers away from each other in the extreme upper and extreme lower position.The third drawback of the design is not envisaged it as a way of overcoming the so-called "dead spots" in the driving process.All these sdet three wheels, composed of two frame parts, truck body, a steering wheel with hand brake and drive, in addition to a chain transfer drive contains articulated lever transmission mechanism comprising two levers of the second kind, the lugs are pivotally connected to the slides contained in the two bonded together guides, by leaving the slider horizontally directed fingers, and shoulder ends provided with rollers having the opportunity to interact with the working surfaces of the clamping mechanism, which consists of a spring and the clamping element with the guide grooves and emphasis, and the fork swivels, engaged in articulated connection with the two sliders rocker mechanism bilateral pedal lever, the Foundation of which is a straight rod located in the middle of the roll, fastened in the sleeve gimbals, whereas the middle part of the transmission levers provide a hinged connection with the cranks are rigidly connected with the leading asterisk on a common shaft.In Fig. 1 is a perspective view of a cargo bike, and Fig. 2 - sketch of the clamping element, with emphasis; Fig. 3 is a drawing of the front of the drive associated with the pedal rich what about the bike presupposes the existence of a frame, composed of two parts: the first part is located in a horizontal plane and is intended for fastening on her body and shaft with two wheels and driven by an asterisk; the second is the vertical arrangement and is equipped with a saddle, wheel and steering control. Parts are made so that at the point of connection of the front part provided in the rear of one of the three necessary points of contact, whereas the other two points of support will come from the rear wheels.In the middle lower part of the cargo module secures the sleeve to the shaft, rigidly connecting sitting on it cranks 6 and the drive sprocket 5. In the rear part of the module has two coaxially interconnected rails 2, the axes of which are arranged in a horizontal plane parallel to the longitudinal axis of the Bicycle. The guides contain the sliders 3, each of which is pivotally connected with the lugs of the transmission levers bike by leaving them perpendicular to the axis of slide horizontally directed fingers 4.Articulated lever mechanism of the transmission, using in their design two levers of the second kind 1, performs kinematic relationship with the leading asterisk 5 by means of the swivel his hand equipped with rollers 9, the rim of which has a tapered shape; mate of the rollers is clamping mechanism includes a clamping element 10 with two deep grooves of corresponding profile, the associated limit stop housing 11 and the compression spring 12. The clamping mechanism is mounted in the middle part of the front frame module by means of the swivel connection that uses existing prijemnom element hole located at a distance of one third from its upper end.The shoulder ends of the levers are articulated coupling connection with swivels in the form of a fork 14, the longitudinal axis of rotation which coincides with the longitudinal axes of the levers. Forklift part swivels pivotally connected to the crosshead 15, planted movably on the pedal rod 13 of the bike.Pedal rod, therefore, is a bilateral arm-wings. The neck pedal rod, who is in the middle, sits rigidly in the sleeve dvukhyadernogo gimbal 17, which is mounted on the bottom of the frame of the front module of the bike.Both ends of the pedal lever is fitted outboard pedals 16, also uses fork swivel 17 as an element dvukhyadernogo swivel.Description of action
The drive sprocket 5, which transmits torque to the shaft driven sprocket 7 and the wheels are driven by means of lever mechanism of the transmission, through the impact of its levers 1 on the cranks 6, is fixed connected with the leading asterisk via a shaft. When this stops levers pivotally connected to the sliders 3, synchronously perform a reciprocating motion, moving together with the slider along the guide rails 2 in opposite directions.The shoulder ends of the levers are equipped with plugs-swivels 14, perform kinematic connection with the pedal lever-wings with the help of swivel swivels with sliders 15, synchronously moving along the foot of the rod 13 on both sides of the point of its connection with cardamomum suspension 17 in the counter-opposite directions.Muscle force through the hanging pedal 16 acts on the pedal lever Bicycle, which, thanks to dvuhgodichnomu connection sitting on the sliders and levers transmission drives the whole system of Bicycle drive.In the moments before overcoming the drive zone "dead" point, it turns out the Xia down lever, and the force of the spring 12 urging him along with the rest 4 to make a straightforward move backward without changing the angular position.Part of the clamping element located above the hinged connection with the frame, also plays an important role in preventing transverse displacement of the trapped at the top of the levers at the time of their descent by rolling the grip rollers with deep walls of the grooves of the clamping element.
