Description

The bicycle servo-unit

Affiliated technical field: the utility model relates to a kind of bicycle work-saving device, is used for bicycle, three-wheel vehicle specifically by the foot-operated servo-unit of manpower.

Background technology: bicycle has become the vehicle that are loved by the people with its facility, quick, pollution-free, noiseless plurality of advantages since coming out, constantly study through people for these years and improve the appearance that just arranged today; But the three-wheel vehicle that how to make bicycle and derive is more brisk, load-carrying ability is bigger, also is the problem that is worth research.

Summary of the invention: the purpose of this utility model provides a kind of bicycle servo-unit that can improve bicycle hill climbing ability, three-wheel vehicle increase load carrying ability.

For achieving the above object, the technical solution of the utility model is to turn greatly at bicycle pedal, the axis periphery that large toothed disk is connected adds an outer shaft, outer shaft one end connects firmly bearing carrier ring successively, bearing, jump ring, the axle envelope, bicycle freewheel, the other end connects firmly inertia wheel successively, the bicycle large toothed disk, bearing carrier ring, bearing, jump ring, the axle envelope, bicycle freewheel, the moving periphery that is assigned in the bicycle middle shaft after the transformation of the way, two ratchet sleeves are fixed on square shaft respectively, bicycle pedal, turn greatly, be fixed on the bicycle middle shaft two ends after the transformation of the way respectively, making it to become has the bicycle of inertia servo-unit.

Employing the utility model has the advantages that: but 1. be used for bicycle speedup on flat road, and uphill road is laborsaving.2. be used for three-wheel vehicle and can improve carrying capacity.3. employed parts are approved product and easy workpiece mostly.4. the country that China is bicycle, the three-wheel vehicle owning amount is maximum, market potential is big.

The specific embodiment: from Fig. 1, Fig. 2, Fig. 3 the utility model as can be seen is first outer shaft shown in Figure 12 5 left ends, connect firmly bearing carrier ring shown in Figure 11 6 successively, bearing 7 shown in Figure 10, card semi-annular jade pendant 8 shown in Figure 9, bicycle freewheel 10 shown in Figure 7, again at outer shaft shown in Figure 12 5 other ends, connect firmly inertia wheel shown in Figure 13 11 successively, bicycle large toothed disk 12 shown in Figure 14, bearing carrier ring 13 shown in Figure 15, bearing 14 shown in Figure 16, card semi-annular jade pendant 15 shown in Figure 17, axle envelope 16 shown in Figure 180, bicycle freewheel 7 shown in Figure 19, the outer shaft 5 that assembles is enclosed within bicycle middle shaft 2 peripheries after the transformation of the way shown in Figure 5, movable assembling, Fig. 6, ratchet sleeve 3 shown in 20,18 are fixed on square shaft 4 places of the bicycle middle shaft 2 after the transformation of the way shown in Figure 5 respectively, again axis 2 two ends are connected firmly Fig. 4 respectively, bicycle pedal shown in 21 turns 1 greatly, 19.

The utility model is work like this: afterburning the turning greatly in bicycle pedal of people's both feet makes the ratchet sleeve 3,18 that is connected on the square shaft 4 stir bicycle freewheel 10,7 on 1 and 19, drive inertia wheel 11 and 12 rotations of bicycle large toothed disk, by chain 20 vehicle is moved ahead, because inertia wheel 11 is heavier, afterburning back is under the effect of being used to power, pedal turn greatly 1 stop reinforcing after, still make vehicle continue to move ahead, thereby reach the power-assisted effect.

For reducing the servo-unit running resistance, establish bearing 7,14, bearing carrier ring 6,13 also has fixation assembly in the foot-operated effect that makes things convenient for the position of car body manpower except that fixed type bearing 7,14, and card semi-annular jade pendant the 8, the 15th prevents that bearing 7,14 strings from employing, and axle envelope 9,16 is used for anti-sand dust.

The utility model bicycle servo-unit is not limited only to bicycle, three-wheel vehicle, and every is that other car and boat of propulsion source are all within the utility model protection domain to ride.
