When the movable pulley 1 is stressed, the guy cable which is wound around the movable pulley enables the one-way bearings on the two half shafts to be simultaneously stressed by the same tensile force to drive the two half shafts. Meanwhile, the inhaul cable 3 of the other cable groove on the same one-way bearing is in a cable retracting state, and drives the other one-way bearing on the same half shaft to move reversely, so that the inhaul cable 2 is in the cable retracting state. When the two half shafts work simultaneously, the movable pulley 2 at the other power input end is in a return ready force application state. When the movable pulley 2 is in the force application state, the movable pulley 1 is in the return ready-to-apply state, so the invention can meet the condition of alternately and sequentially applying force by manpower. When no differential speed occurs between the two half shafts, the rotation speeds of the two half shafts are consistent. When the two half shafts are in differential motion, the cable releasing amount of the cable at the outer periphery of the turn is increased, the cable retracting amount of the cable at the other half shaft is correspondingly increased, the cable releasing amount and the cable retracting amount of the opposite inner periphery half shaft are reduced, and the increasing amounts are correspondingly adjusted and distributed on the movable pulleys.)

1. A differential mechanism features that the wheel center of movable pulley is used as power input point, the pull cable passing around the movable pulley is used as drive unit, two half axles are driven, and the movable pulley is used as differential distributor to realize differential drive.

2. One end of the guy cable which bypasses the movable pulley is fixed in a guy cable retracting groove of the one-way bearing, when the fixed point is pulled by the pulling force of the automatic pulley, the guy cable is lowered, the one-way bearing is pulled to do work to drive the transportation tool, and meanwhile, the guy cable in the other groove position of the same one-way bearing plays a guy cable retracting action to drive the other one-way bearing of the same half shaft to play a guy cable retracting action, so that the return preparation force application state of the.

3. The traction cable is used as a transmission device to drive the transportation tool instead of a chain or a transmission shaft.

Technical Field

A human powered transportation vehicle.

Background

The combination of pulley block, lever (or slide block) and ratchet wheel is used for manpower transport tool driven by parallel power wheels.

Disclosure of Invention

The invention solves the problem of two-wheel speed difference during turning under the condition that the rickshaw needs to be driven by two wheels arranged side by side.

The invention comprises basic components as shown in figure 1, and comprises: the four unidirectional bearings which are installed in the same direction on the half shaft A and the half shaft B are arranged on the two half shafts in two groups, namely Aa, Ab, Ba and Bb. The appearance of each one-way bearing is provided with two circular grooves with rope storage function, and the grooves are respectively named as: aa1, Aa2, Ab1, A2, B1, B2, B1 and B2, two movable pulleys and a plurality of fixed pulleys. Four pull cables.

As shown in the attached figure 2, one end of the stay cable 1 is fixed on the groove Aa1 and winds around the movable pulley and the fixed pulley after being wound for a plurality of circles, and the other end of the stay cable 1 winds around the groove Bb2 and is fixed on the groove Bb2 after being wound for a plurality of circles, so that the stay cable 1 applies force to the one-way bearings Aa and Bb simultaneously under the tension of the movable pulley. In the same way, the inhaul cable 2 is arranged to enable the other movable pulley to apply force to the one-way bearings Ab and Bb under the condition of stress. The winding directions of the cables on the four grooves of Aa1, Bb2, Ab2 and Ba1 are set to generate upward and downward rotating power by the two half shafts when the cables are pulled so as to drive the transport tool, as shown in figure 2. The cable 3 is fixed to the groove Aa2 at one end, wound several times around the fixed sheave and the groove Ab1, and fixed to the groove Ab1 several times, and similarly, the cable 4 is fixed to the grooves Ba2 and Bb1, and the grooves Aa2, Ab1, Ba2, and Bb1 are wound in the opposite direction to the directions Aa1, Bb2, Ab2, and Ba 1.

The working principle is as follows: when the movable pulley 1 is stressed, the pull of the cable which bypasses the movable pulley is transmitted to two ends of the cable, so that the one-way bearings on the two half shafts are simultaneously stressed by the same pull to drive the two half shafts, and at the moment, the cable 1 is released when the wire end is positioned in the groove. Meanwhile, the inhaul cable 3 of the other cable groove on the same one-way bearing is in a cable retracting state and drives the other one-way bearing of the same half shaft to move in the direction, so that the inhaul cable 2 is in the cable retracting state, and when the two half shafts work simultaneously, the movable pulley 2 input by the other power is in a return ready-to-apply state. Similarly, when the movable pulley 2 is in the force application state, the movable pulley 1 is in the return ready-to-apply state, so that the invention can meet the condition of alternately and sequentially applying force by manpower. When the differential speed of the two half shafts is not generated, the rotating speeds of the two half shafts are consistent, and the power guy cables 1 and 2 automatically adjust the cable slots at the two ends of the power guy cables respectively through the movable pulleys to release the cables and retract the cables so that the cable releasing and retracting amount is correspondingly adjusted. When the two half shafts are in differential motion, the cable releasing amount of the cable at the outer periphery of the turn is increased, the cable retracting amount of the cable at the other half shaft is correspondingly increased, the cable releasing amount and the cable retracting amount of the opposite inner periphery half shaft are reduced, and the increasing amounts are correspondingly adjusted and distributed on the movable pulleys.
