When the passenger steps on the pedal with both feet to obtain the forward thrust of the front wheel or the rear wheel, he holds the handle covered with the plastic tube with both hands and turns the hand gear counterclockwise, which can also make the rear wheel or the rear wheel push forward. The front wheel also obtains forward thrust, thereby increasing the speed of the vehicle, and the limbs of the passenger can also be exercised simultaneously, because the rear wheel is two wheels, and the small car seat (22) and the seat are very low, and the car is very stable. , and the car shell can shelter from wind and rain and avoid strong sunlight, so it is especially suitable for the elderly to ride. But when turning the hand gear (8) clockwise with both hands, the front wheel cannot be made to obtain forward thrust.

When the passenger steps on the pedal with both feet to make the front wheel or the rear wheel obtain forward thrust, both hands hold the handle (32) that is covered with a plastic tube at the two ends of the cross bar (29) above the hand push-pull gear bar. ), pull back hard or push forward the longer hand push-pull gear lever to rotate counterclockwise or clockwise, all can make rear wheel or front wheel obtain greater forward thrust again. Since both the front wheels and the rear wheels can obtain forward thrust, the speed of the vehicle can be increased, and the limbs and waist of the rider can also be exercised well. Adjust the power of both feet stepping on the front pedals or hold the handle (32) with both hands and turn the cross bar (29) to change the driving direction. Gripping the sliding hand brake (30) with both hands can stop the cross bar (29) from sliding on the arc-shaped steel pipe (6). Hold the brake hand brake (31) with both hands to slow down or stop advancing. Because the rear wheel is two wheels, the car seat (22) and the seat are very low, the car is very stable, and the car shell can keep out the wind and rain and avoid strong sunlight, so it is especially suitable for the elderly to ride.

The gist of the above-mentioned technical solution is to adopt a group of pedals identical to existing bicycles and transmission gears and transmission chains thereof to be housed between the front end of the vehicle frame and the rotating shaft of the front wheel. Stepping on the pedals can enable the front wheels to obtain forward thrust, and can also change the direction of the vehicle. In front of the rear wheel, under the seat and in front, there is also a set of transmission gears and transmission chains and hand gears connected with the transmission gears through the transmission chains or a set of transmission gears and transmission chains and hand push-pull gears meshed with the transmission gears pole. Turn the hand gear with both hands, or push and pull the gear lever with both hands, and the rear wheel can also be pushed forward. Rotate the push-pull gear lever or rotate the semicircular steel pipe with both hands, also can change the driving direction.

Also can be at the upper end of the rotating shaft in the front-end fixed bearing of vehicle frame above front-wheel slant, fixedly be installed with a larger hand gear, one end of front-wheel rotating shaft (20) is installed with one end that is installed with common bicycle rear-wheel rotating shaft. The smaller transmission gears with the same size and the same structure are connected by an endless transmission chain between the larger hand-turned gear and the smaller transmission gear installed at one end of the front wheel shaft, or fixed at the front end of the frame above the front wheel The lower end of the bearing horizontally fixes the two ends of the rotating shaft in the bearing, and a longer push-pull gear rack is installed, and the transmission gear under the longer push-pull gear rack is meshed with the smaller transmission gear installed at one end of the front wheel shaft or Link to each other by an endless transmission chain, a group of pedals identical with the existing tricycle and transmission gear thereof and the transmission chain connected with the transmission gear in the middle of the rear wheel rotating shaft are installed in the front of the rear wheel. Stepping on the pedals in front of the rear wheels can make the rear wheels get forward thrust, and turning the hand gear on the upper rear of the front wheels with both hands, or pushing and pulling the gear lever on the upper rear of the front wheels with both hands can also make the front wheels gain forward thrust. Turn the push-pull gear lever with both hands to change the driving direction. The purpose of fast fitness driving can be realized with the above-mentioned method.

On the four corners of the rectangular vehicle frame above the rear wheels and the four horizontal flat steel pipe tail ends welded on the upper, lower, left and right sides of the front and rear fixed bearings of the front and rear wheels of the vehicle frame, a bread-shaped vehicle frame is fixedly installed. A detachable bread-shaped car shell is installed on the bread-shaped vehicle frame. Passengers will feel comfortable and convenient when taking this minivan.

Detailed ways

The technical scheme of the present invention is further described in conjunction with above-mentioned accompanying drawing now: in Fig. 1-Fig. 2 is the side view and the top view of the three-wheeled minivan for fast fitness with pedals and hands. As can be seen from the figure: if stepping on the pedal (11) with both feet makes the front wheel obtain the external force forward, hold the pole (26) top rotating shaft (27) two ends with both hands and be covered with the plastic pipe When the handle (30) turns the hand gear (27') counterclockwise, the transmission gear (20) and the transmission gear (9') in the rectangular frame (14) below can be driven by the transmission chain (21) to rotate counterclockwise, and the transmission gear (9 ') drives the transmission chain (12 ') and the moving gear (10) at the right end of the rotating shaft of the rear wheel (18) to rotate counterclockwise, and the moving gear (10) can drive the rear wheel (18) to rotate counterclockwise when rotating counterclockwise , when the rear wheel (18) rotates counterclockwise, it can generate a backward friction force on the ground, and at the same time, the ground produces a forward anti-friction force on the lower edge of the rear wheel (18), and this anti-friction force prevents the rear wheel (18) from descending Sliding along the rear, the forward antistatic friction of the same amount produced by the ground against the lower edge of the rear wheel is the forward external force obtained by the system of the car and the passenger in the horizontal direction, due to the obtained ground The forward external force of and offsets the backward internal force on the system of the passenger and the car, so that the forward internal force on the system of the car and the passenger also becomes the force that pushes the system of the passenger and the car. The thrust by which the system works together to overcome rolling friction. This is the same as the forward external force that the front wheel (1) is obtained from the ground when the rider steps on the pedal (11) with both feet.

The metal box above the rear wheel of the foot-operated hand-turned fast fitness tricycle minivan can not only load a lot of items, but also serve as a seat for people to sit on. The metal box and backrest can lean forward, and the seat occupant can sit facing backward, and the metal box and backrest can also lean back, and the seat occupant can sit facing forward. The two outer ends of the front wheel rotating shaft are respectively equipped with a rectangular elastic thin steel plate (j) that bends backward into a semicircle and is positioned at the front of the pedal to keep out the wind for both legs. Because the rear wheels are two wheels, the car is very stable, and it can also shelter from wind and rain and avoid strong sunlight, so it is especially suitable for the elderly to travel.

Among Fig. 3-Fig. 4 is the side view and the top view of the three-wheeled minivan for pushing and pulling fast by pedals and hands. As can be seen from the figure: when the cyclist steps on the pedal (11) with both feet to make the disc-shaped gear (9) rotate counterclockwise, the disc-shaped gear (9) will drive the endless chain (12) to rotate counterclockwise , the endless chain (12) will drive the moving gear (10) at one end of the front wheel (1) to also rotate counterclockwise. When the moving gear (10) turns counterclockwise, it can drive the front wheel (1) to turn counterclockwise, so that the front wheel The lower edge has a tendency to slide backwards, and produces a backward static friction force against the ground. At the same time, the ground produces an equal amount of forward anti-static friction force against the lower edge of the front wheel, preventing the lower edge of the front wheel from sliding backward. The forward anti-static friction of the same amount produced on the lower edge of the front wheel is the forward external force obtained by the system of the bicycle and the rider in the horizontal direction, because the obtained forward external force from the ground is offset The backward internal force on the system of the rider and the car is eliminated, and the forward internal force on the system of the car and the rider becomes the force that pushes the system of the rider and the bicycle to overcome the rolling friction and move forward. thrust. This is the same as riding a bicycle to make the rear wheel (2) obtain the forward thrust by stepping on the bicycle pedal (5) with both feet. The forward antistatic friction of the same amount produced by the ground against the lower edge of the front wheel is the external cause for the system of the bicycle and the passenger to obtain forward thrust, but it does not do work on the system of the bicycle and the passenger. The force that does work on the system of the bicycle and the rider is the internal force generated by the rider's feet on the bicycle, and the rider is doing work. This is the same as the engine or electric motor of a motor vehicle pushing the wheels to rotate counterclockwise to obtain forward thrust and work.

If stepping on the pedal (11) with both feet makes the front wheel obtain the external force forward, hold the handle (30) with the plastic pipe on the cross bar (29) on the hand push-pull gear bar with both hands, When pulling back the cross bar (29) on the push-pull gear bar to rotate clockwise, the radius of the bottom fixed welding of the hand-push-pull gear bar (12) is that the radius of 15 centimeters is the sector gear (25 ') of 110 °. Will rotate clockwise, and sector gear (25 ') drives the drive gear (15) that meshes with it in the middle of the following rotating shaft (19) but rotates counterclockwise, and the following rotating shaft (19) can rotate counterclockwise. Drive the reverse gear (16) on the right side on the rotating shaft (19) to rotate counterclockwise, but it cannot drive the left gear (16') on the rotating shaft (19) to rotate counterclockwise. When the reverse gear (16) rotates counterclockwise Drive the transmission gear (20) on the right side in the bayonet and the transmission gear (9') on the right side outside the bayonet through the transmission chain (21) to drive the rotating shaft (17) adjacent to it in parallel with it to also rotate counterclockwise, and the transmission gear (9 ' ) drives the ring drive chain (21) to rotate counterclockwise, and the ring drive chain (21) then drives the right side of the rear wheel shaft (17) to rotate counterclockwise, and the right side of the rear wheel shaft (17) to rotate counterclockwise. When rotating, it can drive the rear wheel shaft (17) and the rear wheel (18) to rotate counterclockwise, so that the lower edge of the rear wheel has a tendency to slide backwards, and a backward static friction force is generated on the ground, while the ground faces the lower edge of the rear wheel. A forward equal amount of anti-stiction force is generated to prevent the lower edge of the rear wheel from sliding backwards. The forward equivalent static friction generated by the ground against the lower edge of the rear wheel is the forward external force obtained by the system of bicycle and rider in the horizontal direction, due to the obtained forward force from the ground The external force offsets the backward internal force on the system of the rider and the car, so that the same amount of forward internal force on the system of the bicycle and the rider also becomes the force that pushes the system of the rider and the bike to overcome Forward thrust due to rolling friction. This is the same as the forward external force that the existing bicycle rear wheel obtains the ground to give with the rider who steps on the existing bicycle pedal with both feet.

When pulling back the crossbar (29) on the hand push-pull gear bar to rotate clockwise, the sector gear (25 ') can drive the reverse gear (16) on the right side on the rotating shaft (19) to rotate counterclockwise. Also drive the transmission gear (20 ') on the left side in the bayonet with its parallel adjacent rotating shaft (17) by transmission chain (21) when counterclockwise rotation (16) also rotates counterclockwise. Transmission gear (20 ') can drive the following gear (16 ') on the left side on the front rotating shaft (19) to rotate clockwise when transmission gear (20 ') rotates counterclockwise. But following gear (16 ') but can not drive its rotating shaft (19) to rotate clockwise when rotating clockwise. Promptly transmission gear (20 ') does not act as a hindrance to rotating shaft (19) when rotating counterclockwise. Promptly the moving gear (16) on the left side does not work when pulling back the crossbar (29) on the hand push-pull gear bar and rotates clockwise, only the counter-moving gear on the right side works.

When the passenger is stepping on the pedal (5) with both feet to make the rear wheel (2) obtain the thrust forward, both hands hold the handle (25) that is covered with a plastic tube and push forward the hand push-pull gear lever firmly. When the cross bar (29) rotates counterclockwise, the radius of the push-pull gear bar bottom is that the central angle of 15 centimeters is the sector gear (25 ') of 110 °, which will also rotate counterclockwise, and the sector gear (25 ') drives under it The drive gear (15) engaged with it on the rotating shaft (19) rotates clockwise, but the drive gear (15) and the rotating shaft (19) fixedly connected with it can not drive the rotating shaft (19) when rotating clockwise. The reverse gear (16) on the right side rotates clockwise. Promptly the reverse gear on the right does not work when pushing forward the cross bar (29) on the hand push-pull gear bar and rotates counterclockwise.

But the crossbar (29) that promotes hand push-pull gear lever forward rotates counterclockwise, transmission gear (15) but can drive with it on the left side on the left side of the same rotating shaft along moving gear (16 ') clockwise Rotate, drive the drive gear (20 ') on the back shaft (17) when it rotates clockwise, but it rotates counterclockwise, and the drive gear (20 ') on the back shaft rotates counterclockwise. On the same rotating shaft, the disc-shaped gear (9 ') on the right side outside the bayonet rotates counterclockwise, and when the disc-shaped gear (9 ') rotates counter-clockwise, it drives the clockwise on the right side of the rear wheel (18) rotating shaft through the endless chain (21 '). The moving gear (10') rotates counterclockwise. When the moving gear (10') rotates counterclockwise, it can drive the rear wheel to rotate counterclockwise. When the rear wheel rotates counterclockwise, it can obtain the forward external force given by the ground, that is, to The crossbar (29) of front push hand push-pull gear bar rotates counterclockwise, the following gear (16 ') on the left side works.

But when the cross bar (29) that promotes hand push-pull gear bar forward rotates counterclockwise, the transmission gear (20 ') on the back rotating shaft (17) also can drive and the rotating shaft (17) that is fixedly connected with it when rotating counterclockwise ) on the right side of the drive gear (20) rotates counterclockwise, and when the drive gear (20) rotates counterclockwise, it can drive the reverse gear (16) on the previous rotating shaft (19) to rotate clockwise, and the reverse gear (16) clockwise But can not drive preceding rotating shaft (19) to rotate clockwise when rotating, namely drive gear (20) does not act as a hindrance to rotating shaft (19) when rotating counterclockwise.

It can be seen from the above: when holding the handle (25) on the cross bar that is covered with a plastic tube with both hands and pulling it back firmly or pushing forward the hand push-pull gear lever to rotate counterclockwise or clockwise, the rotating shaft (19) between the two bayonets will One of the reverse gear on the right and the forward gear on the left is always active, so that the rear wheels can obtain the forward thrust given by the ground and move forward, so that the maximum speed can be increased. The hands and feet of the rider can be used together, and the body of the rider can also be fully exercised at the same time.

The metal box above the rear wheel of the foot-operated hand-turned fast fitness tricycle minivan can not only load a lot of items, but also serve as a seat for people to sit on. The metal box and backrest can lean forward, and the seat occupant can sit facing backward, and the metal box and backrest can also lean back, and the seat occupant can sit facing forward. Because the rear wheels are two wheels, the car is very stable, and it can also shelter from wind and rain and avoid strong sunlight, so it is especially suitable for the elderly to travel.

In Fig. 5-Fig. 6 are the front view and the side view of the three-wheeled minivan for fast exercise with hand-turned pedals. The cyclist holds the handle (25) that is covered with plastic pipe with both hands while stepping on the front pedal (5) of the rear wheel (2) with both feet to make the rear wheel (2) obtain forward thrust. Turn the hand gear (8) counterclockwise, the hand gear (8) drives the circular transmission chain (11), and the circular transmission chain (11) drives the smaller transmission gear (21) installed at one end of the front wheel shaft (20) to rotate counterclockwise , the smaller transmission gear (21) drives the front wheel (1) to rotate counterclockwise, causing the lower edge of the front wheel to slide backwards and generate a backward static friction force against the ground. A forward equal amount of anti-static friction prevents the lower edge of the front wheel from sliding backwards. The forward equal amount of anti-static friction generated by the ground against the lower edge of the front wheel is the level of the system between the car and the passenger. The forward external force given by the ground obtained in the direction obtained, because the obtained forward external force given by the ground offsets the backward internal force suffered by the system of the passenger and the car, so that the car and the passenger The forward internal force on this system can push the occupant and the system together to overcome the rolling friction and move forward. The forward internal force suffered by the system of the vehicle and the passenger is the thrust that pushes the system of the vehicle and the vehicle forward. The prerequisite for the forward internal force on the vehicle and passenger system to become the forward thrust of the vehicle and passenger system is to obtain the forward force given to the vehicle and passenger system by the ground at the same time. Equivalent external force (static friction). This is the same as the passenger is stepping on the pedal (5) with both feet to make the rear wheel (2) obtain the forward external force given by the ground and advance the same, and also obtains the force given by the ground with the driving wheel behind all motor vehicles. It is the same as moving forward with an external force. But what do work is not the forward external force (frictional force) given by the ground that the driving wheel obtains, but the internal force of the system of the car and the passenger is doing work. For bicycles and tricycles, in fact, the rider is doing work, and what is consumed is the internal energy of the person. For a motor vehicle, the work is actually done by the machine, and what is consumed is the internal energy or electric energy of the fuel in the machine.

The metal box under the seat above the rear wheels of the fast fitness tricycle minivan with hand-turned pedals can be loaded with many items. Because the rear wheels are two wheels, the seat is low, the car is very stable, and it can also shelter from wind and rain and avoid strong sunlight, so it is especially suitable for the elderly to travel and ride.

Among Fig. 7-Fig. 8 is the front view and the side view of the hand-pull foot-operated fast fitness tricycle minivan. As can be seen from the figure: when the passenger is stepping on the pedal (5) with both feet to make the rear wheel (2) obtain forward thrust, both hands hold the handle (25) that is covered with a plastic tube When pulling the horizontal steel pipe (12") above the push-pull gear frame, the lower right corner of the rectangular steel frame (12) of the push-pull gear frame is fixed and welded with a radius of 15 cm and clamped on the right side of the front wheel by two struts (16") The quarter disc gear (13) in the middle will also rotate clockwise, and the quarter disc gear (13) drives the smaller gear (13) engaged with it on the rotating shaft (23 '). ) rotates counterclockwise, and the smaller gear (13) drives another larger gear (13) on the rotating shaft (23 ') with it to also rotate counterclockwise, and the other larger gear (13) drives the endless transmission chain (14 ) rotates counterclockwise, and the endless drive chain (14) then drives the front wheel to rotate counterclockwise, so that the lower edge of the front wheel will slide backwards and produce a backward static friction force against the ground. A forward equal amount of anti-static friction prevents the lower edge of the front wheel from sliding backwards. The forward equal amount of anti-static friction generated by the ground against the lower edge of the front wheel is the level of the system between the car and the passenger. The forward external force obtained from the direction, because the obtained forward external force from the ground counteracts the backward internal force suffered by the system of the vehicle and the vehicle, so that the system of the vehicle and the vehicle suffers The forward internal force can push the occupant and the car system together to overcome the rolling friction and move forward. This is the same as the cyclist stepping on the pedal (5) with both feet to make the rear wheel (2) obtain the forward external force that the ground gives. But when the smaller transmission gear (21) on the left side of the front wheel rotates clockwise, it can not drive the front wheel to rotate clockwise, more can not drive the front wheel to rotate counterclockwise, and can not obtain the forward external force given by the ground.

When the passenger is stepping on the pedal (5) with both feet to make the rear wheel (2) obtain the thrust forward, both hands hold the handle (25) that is covered with plastic pipe and push forward the hand push-pull gear frame firmly. When the upper horizontal steel pipe (12") is fixed, the lower right corner of the rectangular steel frame (12) is fixedly welded with a radius of 15 cm, which is a quarter disc-shaped gear sandwiched between the two struts (16 ") on the right side of the front wheel (13) will also rotate counterclockwise, and a quarter disc gear (13) drives the smaller gear (13) engaged with it on the rotating shaft (23 ') to rotate clockwise, and the smaller gear (13) ) drives another larger gear (13) on the rotating shaft (23 ') with it to also rotate clockwise, and another larger gear (13) drives the circular transmission chain (14) to rotate clockwise, and the circular transmission chain (14 ) but cannot drive the front wheels to rotate clockwise, let alone drive the front wheels to rotate counterclockwise, and cannot obtain the forward external force given by the ground.

But the quarter disc gear (13) in the middle of two struts (16 ") on the left side of the front wheel will also rotate counterclockwise with the right one, and the quarter disc gear (13) on the left side drives the The bigger gear (13) engaged with it on the rotating shaft (23 ') rotates clockwise, and the gear (S) driven by the bigger gear (13) on the left side of the front wheel shaft rotates counterclockwise. When the gear (S) rotates counterclockwise, it can drive the front wheel to rotate counterclockwise, so that the lower edge of the front wheel has a tendency to slide backward, and a backward static friction force is generated against the ground, and at the same time, the ground generates a forward force against the lower edge of the front wheel. The same amount of anti-static friction force prevents the lower edge of the front wheel from sliding backward, and the forward equal amount of anti-static friction force generated by the ground against the lower edge of the front wheel is obtained by the system of the car and the passenger in the horizontal direction. The forward external force, because the obtained forward external force from the ground counteracts the backward internal force on the system of the vehicle and the vehicle, so that the forward force on the system of the vehicle and the vehicle The internal force can push the rider and the car system together to overcome the rolling friction and move forward. This is the same as when the rider steps on the pedal (5) with both feet to make the driving wheel of the rear wheel (2) obtain ground support. It is the same as moving forward with an external force.

That is, when the passenger is stepping on the pedal (5) with both feet to make the rear wheel (2) obtain forward thrust, both hands hold the handle (25) that is covered with a plastic tube and push forward the hand push-pull gear firmly. When the horizontal steel pipe (12 ") above the frame is installed, the rotation of the quarter disk gear (13) in the middle of the two poles (16 ") on the right side of the front wheel cannot drive the front wheel to rotate counterclockwise, and the ground that cannot be obtained To move forward with the forward external force, the rotation of the quarter disc gear (13) in the middle of the two struts (16") on the left side of the front wheel can drive the front wheel to rotate counterclockwise, and the ground can be given forward external force to move forward.

It can be seen from the above: when holding the handle (25) that is covered with a plastic tube with both hands and pulling it back firmly or pushing forward the horizontal steel pipe (12 ") above the hand push-pull gear frame, the front wheels can obtain the forward force provided by the ground. The vehicle is driven forward by external force, so that the speed of the vehicle can be further improved, and the body of the passenger can also be better exercised at the same time.

The metal box under the seat above the rear wheels of the foot-operated push-pull fast fitness tricycle minivan can load many items. The two outer ends of the front wheel rotating shaft are respectively equipped with a rectangular elastic thin steel plate (j) that bends backward into a semicircle and is positioned at the front of the pedal to keep out the wind for both legs. Because the rear wheels are two wheels, the seat is low, the car is very stable, and it can also shelter from wind and rain and avoid strong sunlight, so it is especially suitable for the elderly to travel and ride.

In Figure 9 is a side view of the drive gear (16'). As can be seen from the figure: it has the same structure as the following gear (10, 10 ') at the right end of the rear wheel rotating shaft of existing bicycles and tricycles, but the thickness is larger, and the radius is 5 centimeters and slightly larger. But their activity process is different: along moving gear (16 ') is that rotating shaft drives the outer gear to rotate, and following moving gear (10,10 ') is that the outer gear drives rotating shaft to rotate.

In Figure 10 is a side view of the reverse gear (16). As can be seen from the figure: as can be seen from the figure: it is made of a disc (29) fixedly connected with the rotating shaft, a circular ring that is enclosed within the outer edge of the disc (29) and has gears that can rotate around the disc. (30) is formed, along the groove (31,31 ') that has some identical intervals in the outer edge of the disc (29) and the inner edge of the annulus (29), each groove (31 ') on the outer edge of the disc (29) ) has a small stop (32), the small stop (32) can be completely immersed in the groove (31), and can rotate around the rotating shaft (33) at its right end, the middle part of the small stop (32) has a Small hook (34), an annular elastic thin steel wire (35) passes below the small hook (34), the rotatable left end of the small stopper (32) is pushed out of the groove, and the groove ( 31'), and in close and smooth contact with the groove (31').

The difference in the structure of the reverse gear (16) and the forward gear (16') is: the position of the small rotating shaft (37) of the small stop (36) is different, and the small rotating shaft of the small stop (36) in the reverse gear (16) (37) is on the right, and that of the moving gear (16') is on the left; the radius of the counter-moving gear (16) is the same as that of the moving gear (10, 10 ') at the right end of the rear wheel shaft, and is higher than that of the moving gear (16'). slightly smaller. Other structures are identical.

When the sector gear (25 ') drove the drive gear (15) and the rotating shaft (19) to rotate counterclockwise, the disk (33) in the counter gear (16) fixedly connected to the rotating shaft (19) would also rotate counterclockwise. Since the left end of the small stop (36) has fallen into the groove (35 ') on the inner edge of the ring, when the rotating shaft (19) rotates counterclockwise, the left end of the small stop (36) can face the groove (35 '). Longitudinal pressure is generated, and the anti-longitudinal pressure of the groove (35') on the small stopper (36) cannot push the small stopper (36) into the groove (35') due to passing through the small rotating shaft (37), so the small stopper Head (36) can push the disk with gear on the outer edge of itself to rotate counterclockwise, and the disk drives the drive chain (21) to rotate counterclockwise, and the drive chain (21) drives the transmission gear ( 20), the transmission gear (10 ') of disc gear (9 '), transmission chain (9 ') and rear wheel rotating shaft right end rotates counterclockwise. When the sector gear (25 ') drives the transmission gear (15) and the rotating shaft (19) to rotate clockwise, the disc (33) fixedly connected to the rotating shaft (19) will also rotate clockwise. Though the left end of little stopper (36) has fallen in the groove (35 ') along the ring, the left end of little stopper (36) leaves the contact surface of groove (35 '), only side and circle Lateral pressure is generated between the sides of the groove along the inner ring, and this lateral pressure presses the left end of the small stopper (36) back into the groove, so the small stopper (36) cannot push the disc with the gear on its outer edge Rotate clockwise together, promptly reverse gear (16) does not work when rotating clockwise.
