Technical Field

The invention relates to the field of mechanical transmission; in particular to a multipurpose driving device of a vehicle, which is used for power transmission of a bicycle or an electric moped.

Background

The manpower vehicles such as bicycles and the like generally adopt a transmission mode that a chain and a pedal do circular motion, and the transmission mode has the problems of chain transmission loss and acting force dead angles when the pedal does circular motion; secondly, the common bicycle has only one driving mode and single function; in order to overcome the defect of chain transmission, whether the pedal crank directly acts on the driving wheel to realize direct driving or not can be realized; or the pedal is driven by a rope to do reciprocating motion so as to overcome the dead angle problem of acting force of the pedal in circular motion; a very large number of people have performed countless compensation trials; however, it is very difficult to realize direct drive or rope drive, and the transmission device has an extremely complicated structure, high cost, or a simple structure and low performance, and has no ideal realization scheme so far.

The middle gear shaft 9 and the middle gear shaft 10 are rigidly connected with the central shaft 1.

The left inner flywheel 4 and the right inner flywheel 11 adopt inner flywheel structures; the inner flywheel means that the outer ring of the flywheel is rigidly connected with the drum barrel, and the inner ring of the flywheel can rotate; in a similar way, the outer ring of the outer flywheel can rotate, and the inner ring of the outer flywheel is rigidly connected with the drum barrel.

The left inner flywheel 4 and the right inner flywheel 11 are in threaded connection with the drum barrel 6; looking at the drum barrel 6 from the left end, the inner ring of the left inner flywheel 4 can rotate freely clockwise; when the inner ring of the left inner flywheel 4 rotates anticlockwise, the inner ratchet wheel and the pawl are meshed to drive the wheels to rotate together; when the right end of the hub barrel 6 is seen, the inner ring of the right inner flywheel 11 can rotate freely counterclockwise, and when the inner ring of the right inner flywheel 11 rotates clockwise, the inner ratchet wheel and the pawl are meshed to drive the wheels to rotate together.

The bevel gear handles of the left bevel gear 3 and the right bevel gear 12 adopt spline shaft structures; the left bevel gear 3 is connected with the left inner flywheel 4 by a spline shaft and a spline shaft sleeve; the right bevel gear 12 is connected with the right inner flywheel 11 by a spline shaft and a spline shaft sleeve.

The left end and the right end of the central shaft 1 are respectively and rigidly connected with the frame.

As shown in fig. 4, characterized by comprising a sprocket 13; the sprocket 13 is mounted on the bevel gear shank of the right bevel gear 12; the chain gear 13 and the right bevel gear 12 are connected by a spline shaft and a spline shaft sleeve.

As shown in fig. 5, it is characterized by comprising a left U-shaped grooved wheel 14, a right U-shaped grooved wheel 15; the left U-shaped grooved wheel 14 is arranged on a bevel gear handle of the left bevel gear 3; the right U-shaped grooved wheel 15 is mounted on the bevel gear shank of the right bevel gear 12; the left U-shaped grooved pulley 14 is connected with a bevel gear handle of the left bevel gear 3 by a spline shaft and a spline shaft sleeve; the right U-shaped groove wheel 15 is connected with the bevel gear handle of the right bevel gear 12 by a spline shaft and a spline shaft sleeve.

As shown in fig. 6, it is characterized by comprising a left pedal crank 16, a right pedal crank 17; a left pedal crank 16 is arranged on the bevel gear handle of the left bevel gear 3; a right pedal crank 17 is mounted on the bevel gear handle of the right bevel gear 12; the left pedal crank 16 is connected with the bevel gear handle of the left bevel gear 3 by a spline shaft and a spline shaft sleeve; the right pedal crank 17 is connected with the bevel gear handle of the right bevel gear 12 by a spline shaft and a spline shaft sleeve.

The working principle is as follows:

the multipurpose drive apparatus as described in fig. 1;

when the right bevel gear 12 rotates clockwise under external force, the right bevel gear 12 causes the ratchet wheel and the pawl inside the right inner flywheel 11 to be meshed and drives the wheel to advance;

meanwhile, the right bevel gear 12 enables the left bevel gear 3 to reversely rotate through the middle bevel gear 7 and the middle bevel gear 8;

the left bevel gear 3 drives the left inner flywheel 4 to rotate reversely, and at the moment, the ratchet pawl inside the left inner flywheel 4 freely rotates in a non-meshing state.

When the right bevel gear 12 rotates anticlockwise under external force, the right bevel gear 12 drives the inner ring of the right inner flywheel 11 to rotate anticlockwise, and at the moment, the ratchet wheel and the pawl inside the right inner flywheel 11 rotate freely without meshing;

meanwhile, the right bevel gear 12 enables the left bevel gear 3 to rotate reversely through the middle bevel gear 7 and the middle bevel gear 8, and the left bevel gear 3 enables the ratchet wheel inside the left inner flywheel 4 to be meshed to enable the wheel to move forwards.

Therefore, the right bevel gear 12 can drive the vehicle to move forwards no matter clockwise or anticlockwise stressed; if the driving device is adopted to replace a hub and a flywheel of a common bicycle, the bicycle can move forward no matter the pedal is stepped forward or backward, thereby changing into a fancy stepping bicycle.

As shown in fig. 6, a left pedal crank 16 and a right pedal crank 17 are mounted on the bevel gear shanks of the left bevel gear 3 and the right bevel gear 12, respectively; when the left pedal is pedaled, the left bevel gear 3 is driven, the left bevel gear 3 drives the left inner flywheel 4 to rotate, and at the moment, the ratchet wheel and the pawl inside the left inner flywheel 4 are meshed to enable the wheel to move forwards.

Meanwhile, the left bevel gear 3 enables the right bevel gear 12 to rotate reversely through the middle bevel gear 7 and the middle bevel gear 8; the right bevel gear 12 drives the right pedal to lift, and simultaneously the right bevel gear 12 drives the right inner flywheel 11 to rotate, and at the moment, the ratchet and pawl inside the right inner flywheel 11 rotate freely without meshing.

Similarly, when the right pedal is stepped down, the right inner flywheel 11 drives the wheels to move forwards, and simultaneously the left pedal is lifted; the stepping movement can make the bicycle move forward to form a direct-drive bicycle.

As shown in fig. 5, a left U-shaped grooved pulley 14 and a right U-shaped grooved pulley 15 are respectively installed on the bevel gear handles of the left bevel gear 3 and the right bevel gear 12, and a traction rope is installed on the two U-shaped grooved pulleys; when one side haulage rope atress is tensile, can make the opposite side haulage rope shrink, drive the wheel simultaneously and move ahead, the reciprocal receipts of both sides haulage rope just can make the wheel continuously move ahead to become the reciprocal bicycle of trampling of rope drive.
