Description

Lever driven bicycle

Technical field

The utility model relates to a kind of bicycle, specifically, relates to a kind of lever driven bicycle.

Background technology

Existing bicycle generally all is to adopt chain gear, also has the partially self car to adopt other type of drive, such as transmission shaft transmission or gear transmission etc.; In recent years, begin to occur the bicycle of lever transmission on the market, the bicycle of lever transmission utilizes the lever principle can be laborsaving, and can be under the effect of the same application of force raising speed.

At present, existing lever driven bicycle on the market, generally include vehicle frame, trailing wheel, be installed in the rear axle on the vehicle frame, be fixed on the rear wheel gear on the trailing wheel, with rear wheel gear ingear driven wheel, be installed in the rotating shaft on the vehicle frame, be fixed on the actuating arm of rotating shaft one end, be arranged on the strip chute on the actuating arm, transmission levers, be arranged on the bolster of transmission levers side, be installed in the pedal rotating shaft on the vehicle frame, be fixed on the pedal pivoted arm of pedal rotating shaft one end, wherein, described trailing wheel and described rear wheel gear are installed on the described rear axle, described driven wheel is installed in the described rotating shaft other end, described transmission levers one end and described pedal pivoted arm outer end are hinged, the straight line chute is installed on described vehicle frame, described bolster is arranged in the described straight line chute, described transmission levers other end side is provided with slide shaft, and described slide shaft is arranged in the strip chute of described actuating arm;

As shown in Figure 1, the motion principle of existing lever driven bicycle is: described pedal pivoted arm 1 is made circular movement around described pedal rotating shaft 10, described bolster 4 is moving linearly in described straight line chute 28, described actuating arm 5 is made circular movement around described rotating shaft 16, and the slide shaft 22 of described transmission levers 3 is done ellipse or sub-elliptical motion in described strip chute 21; Promptly drive described transmission levers 3 motions by described pedal pivoted arm 1, described transmission levers 3 drives described actuating arm 5 motions by described slide shaft 22 and described strip chute 21, and with the ellipse of described slide shaft 22 or the circular movement of the described actuating arm 5 of sub-elliptical motion changing into, drive described driven wheel with this, and drive described rear wheel gear and described rear wheel movement by described driven wheel;

But, when the motion of ellipse or sub-elliptical changes circular movement into because sliding phenomenon is arranged, change apart from or discontinuity, when riding, whenever rotate a circle and step on empty sensation for twice, make the people very uncomfortable.

In order to overcome the above problems, people are seeking a kind of desirable technical solution always.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, thereby provides a kind of and be skillfully constructed, ride comfortable, labour-saving lever driven bicycle.

To achieve these goals, the utility model provides a kind of lever driven bicycle, comprise vehicle frame, trailing wheel, be installed in the rear axle on the vehicle frame, be fixed on the rear wheel gear on the trailing wheel, with rear wheel gear ingear driven wheel, be installed in the rotating shaft on the vehicle frame, be fixed on the actuating arm of rotating shaft one end, transmission levers, be arranged on the bolster of transmission levers side, be installed in the pedal rotating shaft on the vehicle frame, be fixed on the pedal pivoted arm of pedal rotating shaft one end, described trailing wheel and described rear wheel gear are installed on the described rear axle, described driven wheel is installed in the described rotating shaft other end, described transmission levers one end and described pedal pivoted arm outer end are hinged, on described vehicle frame, circular orbit slot is installed, described bolster is arranged in the described circular orbit slot, and the described transmission levers other end and described actuating arm outer end are hinged.

Based on above-mentioned, the circular orbit ovalize of described circular orbit slot.

Based on above-mentioned, the circular orbit of described circular orbit slot is approximate ellipsoidal.

The relative prior art of the utility model has substantive distinguishing features and progress, specifically, this bicycle improves the lever drive mechanism, promptly the support motion track of bolster is changed into annular trace by original straight path, and the path of motion of drive link bar end is changed into the circular movement track by sub-elliptical path of motion; It can come out the advantage applies of lever force-saving, can eliminate the empty sense of stepping on when riding again; It has comfortable, the labour-saving advantage that is skillfully constructed, rides.

The specific embodiment

Below by the specific embodiment, the technical solution of the utility model is described in further detail.

As shown in Figures 2 and 3, a kind of lever driven bicycle, comprise vehicle frame 13, trailing wheel 14, be installed in rear axle 15 on the vehicle frame 13, be fixed on the rear wheel gear 7 at trailing wheel 14 centers, with rear wheel gear 7 ingear driven wheels 6, be installed in the rotating shaft 16 on the vehicle frame 13, the actuating arm 5 that is vertically fixed on rotating shaft 16 1 ends, transmission levers 3, be arranged on transmission levers 3 sides bolster 4, be installed in pedal rotating shaft 10 on the vehicle frame 13, be vertically fixed on the pedal pivoted arm 1 and the pedal pivoted arm 11 at pedal rotating shaft 10 two ends respectively;

For hinged convenience and foot-operated pedal are comfortable, vertical fixing has adapter shaft 2 and adapter shaft 12 respectively in pedal pivoted arm 1 and pedal pivoted arm 11 outer ends, and at adapter shaft 2 and adapter shaft 12 outer ends one side pedal 9 and pedal 19 is installed respectively;

Wherein, rear axle 15, rotating shaft 16, pedal rotating shaft 10, adapter shaft 2, adapter shaft 12 are arranged in parallel; Actuating arm 5 equals pedal pivoted arm 1 and pedal pivoted arm 11 respectively around the radius of rotation of pedal rotating shaft 10 around the radius of rotation of rotating shaft 16;
