The invention relates to a device for actuating vehicle by the muscular energy of the person.
Famous bike with pedal actuator comprising sprocket, chain drive being connected to driven sprocket mounted on the shaft of the carriage rods associated with pedals and an additional drive on the saddle, which has a kinematic connection is made through a rod, pivotally connected with additional rod mounted opposite to the connecting rods of the foot. This pedal drive is justified on the effects of muscular energy of the feet on the pedals, periodic transition to the influence of its own weight of the cyclist.
However, such an impact, accompanied by a rise building on the legs and lowering the saddle, applying energy to the additional rod its own weight, can lead to rapid fatigue of the rider and may cause difficulties in the management of the bike, in addition, when such movements of the rider is very difficult to overcome steep slopes.
Known also drive the bike for the patent containing a two-stage transmission, the first stage of which has driving and driven sprockets, covered chain transmission, the second stage has a drive sprocket mounted on the same axis with the first slave and the associated driven sprocket Deut the stage, installed at the rear wheel, and sprocket of the second stage is performed with a variable radius, and stars of the first stage is performed with a constant radius with a gear ratio equal to two.
This drive creates some relief at the beginning of the rotation of the crank from the top point, as this matches the smallest radius of the sprocket of the second stage, however, the disadvantage is the fact that because of the variable built the radius of the sprocket of the second stage movement of the Bicycle may be accompanied by the jerks, creating interference for pedaling.
Known also drive the bike on the patent of Russian Federation №2068364 containing two-stage transmission comprising sprocket rigidly mounted on the shaft of the carriage is connected by means of the chain drive driven sprocket, fitting the leading wheel and pedal, in which the first stage actuator is made of two mechanisms planetary execution in the composition of the carrier rigidly connected with the shaft of the carriage and freely mounted on the protruding ends of the satellites that are associated gear ratio equal to one, with a sun gear units mounted concentric to the shaft of the carriage with two gross parties movably to the vehicle body, and the pedals are installed on the rear ends of the horizontal is x one shoulder levers, strictly based front ends to the axes of the satellites, and, in the first embodiment, each satellite and solar star of the planetary mechanism is connected with a chain, and the second planetary gear consists of a cylindrical sun gear and the cylindrical satellite, which are interconnected by means of the intermediate gear, or more odd number of gears mounted on the free axes, based on the carrier; in the third embodiment, each planetary gear consists of a conical sun gear and tapered satellites, which are interconnected by means of the intermediate roller is rigidly mounted bevel gears on the ends, freely supported on the carrier, and to realize the possibility of braking the rotation of the Dobby shaft ago, the front ends of the horizontal arms, above the point of their connection with satellites installed brake pads, in addition, with the goal of expanding the range of pedaling by changing the radius of the crank carrier is made of two parts, pivotally interconnected at the level of the intermediate gear mounted freely on a common axis, providing the possibility of establishing a specific center distances between the satellite and the sun gear, and a connection, however, gorizontalnom anoplocephala lever with satellite performed using the overrunning clutch.
Such wheel drive improves traction ability, reduces fatigue cyclist, easier pedaling, but not completely eliminates slip and for high values of the rotational speed of the wheels requires a large number of intermediate gears, which leads to a significant reduction of the efficiency of the drive.
The set of essential characteristics specified technical solution according to the patent of Russian Federation №2068364 adopted for the prototype.
The aim of the invention is to increase the traction ability and increase the efficiency of the drive.
The objective is achieved due to the fact that in the inventive pedal drive with the first stage actuator is made of two planetary gears with the carrier and rigidly connected with the shaft of the carriage which is freely mounted on the protruding ends of the satellites, meshed with a gear ratio equal to one, with a sun gear units mounted concentric with the shaft of the carriage with two sides and is stationary relative to the vehicle body, and a pedal mounted on the radial ends of the horizontal levers, always directed forward, and the axial ends of the horizontal arms are rigidly connected with satellites, while the sludge produced in the form of discs and with the shaft of the carriage are the flywheel, and the second step is made gear wheel which is fixedly mounted on the rim of the carrier and the gear mounted on the drive axis of one of the actuators of the vehicle.
Use disk drove as flywheel is much easier pedaling, because the rotation when passing the dead point at the expense of the moment of inertia of the flywheel and it requires no additional effort cyclist and any special skills. Easier pedaling in the inventive actuator becomes possible the use of large along the length of the horizontal levers, which leads to an increase of the traction capability of the drive. The execution of the second-speed drive gear with a much larger gear ratio than used everywhere in the chain transmission, allows to obtain large coefficients of reduction without the use of multiple gears, which greatly increases the efficiency of a pedal drive.
Thus the claimed design meets the criteria of the invention of "novelty."
The comparison of the proposed solutions not only prototype, but also with other technical solutions in this field of technology is not allowed to reveal in them the features distinguishing the claimed solution to the prototype that is allows to make a conclusion on compliance with the criteria of the invention "significant differences".

Pedal drive with increased towing capacity includes the body (Figure 1) 9, in which two-speed drive, the first of which includes two planetary mechanism performance in the two drove 2 and 3 rigidly mounted on the shaft of the carriage 1, is installed freely on the edges drove 2 and 3 satellites 4 and 5, which are connected toothed-belt transmission with spaced concentric to the shaft of the carriage 1 and rigidly connected to the housing 9 sun gear units 7 and 8 gear ratio equal to one. The pedals 10 and 11 are installed on the radial ends of the horizontal arms 12 and 13, which are always directed forward, and their axial ends are rigidly connected with satellites 4 and 5. The second stage is made gear comprising a toothed wheel 16, which is rigidly secured to the rim of the carrier 2, and the gear 17 mounted on the drive axis 18 of one of the actuators of the vehicle.
Pedal drive with increased towing capacity is as follows:
the force produced by velomobiles turn the pedals 10 and 11, mounted on the radial ends of the horizontal arms 12 and 13, respectively, is transmitted to the satellites 4 and 5, which have a rigid connecting the axial ends of the horizontal arms 12 and 13 and mounted on the edges of the led 2 and 3 with the possibility of free rotation. Because the satellites 4 and 5 are connected by a toothed-belt transmission with fixed relative to the vehicle body 9 sun gears 7 and 8, resulting from efforts torque shall turn drove 2 and 3 together with the shaft of the carriage 1 and the wheel 16 of the second stage actuator in the forward direction of movement of the recumbent. Simultaneously, the satellites 4 and 5 to pass along the trajectory radius of the crank angular velocity and interacting with the solar units 7 and 8 provide a plane-parallel horizontal movement of the levers 12 and 13 is always directed forward and perpendicular to the direction of application of force to the pedals 10 and 11, the radius of application of force to the pedals relative to the axis of the carriage 1 is changed from the minimum to the rearmost position of the levers 12 and 13 to a maximum at their extreme forward position, and the pedal 10 and 11 make a circular rotation in the right circle with radius equal to the distance from the axis of the carriage 1 to the axis of the satellites 14 and 15 (optimal length - 170 mm), providing the usual process of pedaling.
Manufacturing has been leading in the form of discs and use them as the flywheel is much easier pedaling due to the passage of "dead spots" due to the inertia of the flywheel, and application of gears in vtora the speed of the drive increases its efficiency and provides a much greater rate reduction compared with chain transmission.
Pedal drive with increased towing capacity makes it easier pedaling, contributing to a sharp reduction in fatigue of velomobiles and more efficient use of his efforts, increase speed by increasing traction ability, makes it widely used in various combinations with hydraulic, pneumatic and electrical mechanisms in vehicles and other engineering fields.
