Abstract
The utility model relates to a pedal type speed variable planetary transmission device which is mainly composed of a left pedal, a right pedal, a left rocking rod, a right rocking rod, a left crank, a right crank, a bicycle shaft, a planetary wheel rack, a large planetary wheel, a small planetary wheel, an inner tooth ring, a central tower wheel, a flywheel, a bicycle wheel hub, a shifting fork, a guiding post and a spring. The pedals are pedaled to move up and down to replace the circumferential rotation of a foot crank of the existing bicycle, and the middle shaft part, a tooth disk and a chain of the existing bicycle are omitted. The utility model has the characteristics of speed variability, labor saving, compact structure, small volume, safe and reliable operation, etc., can be used as a transmission device on machinery, such as bicycles, etc.
Description
The utility model is a kind of bicycle or other mechanically operated pedal type adjustable speed planetary driving device of being applicable to.
Existing transmission mechanism of bicycle mainly by pin turn, fluted disc, chain and flywheel form; Manpower steps pin, and to turn consumption power big, and chain easily elongates, and falls chain, the easy dirty clothing of rider.
The purpose of this utility model provides a kind of pedal type adjustable speed planetary driving device that is applicable to bicycle or other mechanical usefulness, to overcome the deficiencies in the prior art.
The purpose of this utility model is achieved in that pedal type adjustable speed planetary driving device mainly is to be assembled by left-hand tread plate, right-hand tread plate, left crank, right crank, left rocking bar, right rocking bar, axletree, planetary wheel carrier, major planets wheel, asteroid wheel, center cone pulley, flywheel, wheel hub, internally toothed annulus, shift fork, guidepost, spring; It is installed on the bearing seat of the left and right end welding of back fork of bicycle, steps left and right pedal, wheel can rotate forward.Left and right crank is separately fixed at the axletree two ends, is mutually 180 degree; Be fixed with planetary wheel carrier on the axletree; Little axle and bearing are housed in the middle of large and small satellite gear and the planetary wheel carrier; The center cone pulley is captiveed joint with the flywheel external toothing; The flywheel inner bolt hole is captiveed joint with wheel hub; Left and right pedal and left and right rocking bar are equipped with bearing respectively between the left and right crank; Left and right bearing seat extendible portion on left and right rocking bar and the vehicle frame back vent is equipped with bearing respectively; Wheel hub and axletree, the left and right bearing seat on axletree and the vehicle frame back vent is equipped with bearing respectively.Step left and right pedal and can make left and right crank, axletree, the unidirectional continuous rotation of planetary wheel carrier; Large and small satellite gear is done rotation and revolution along internally toothed annulus and center cone pulley; Internally toothed annulus is fixed, and big or asteroid wheel promotes center cone pulley and flywheel, and wheel hub rotates together.
Realize that above-mentioned motion is owing to the constraint of left and right rocking bar to left and right pedal; Guidepost restriction internally toothed annulus circumferentially rotates; Adopt planetary transmission speedup principle just to finish.
Left and right crank, planetary wheel carrier, center cone pulley, flywheel, wheel hub are installed on the same axletree; Flywheel is fixed in the wheel hub annular groove; Make total very compact.
Regulating mechanism is flexibly connected by shift fork and internally toothed annulus, and shift fork and vehicle frame back vent right bearing seat extendible portion flexibly connect; Stir shift fork internally toothed annulus is meshed with major planets wheel or asteroid wheel respectively, realize the purpose of speed governing.
The utility model has adopted planetary transmission speedup principle, has compact conformation, characteristics that volume is little; The mechanical analysis radial component approximates zero, and driving efficiency is high, computing value: η=0.982 in the time of fast, η in the time of at a slow speed=0.985; Pedal partly adopts quadric linkage, pedal steps the stressed optimum position of stressed crank drive just downwards, therefore littler than the loss of exerting oneself of the bicycle of existing fluted disc, chain gear, starting is fast, does not also have the chain elongation, falls phenomenons such as chain, the easy dirty clothing of rider; Regulating mechanism adopts the shift fork principle, and simple in structure, appliance is few; In a word, improved safety and reliability that bicycle uses, shown also on the structure that reducing maintenance is suitable for practical characteristics.

Fig. 4. be the scheme drawing that is assemblied on the bicycle
1.2.3.4. elaborates to the utility model in conjunction with the accompanying drawings.
Transmission of the present utility model is finished like this, manpower steps left-hand tread plate (1) because the constraint of left rocking bar (6), promote left crank (3) and produce α ° of casterangle, simultaneously, the right crank (4) that is fixed on axletree (5) right-hand member upwards rotates thereupon and produces α ° of front rake, because the constraint of right rocking bar (7), right-hand tread plate (2) lifts, manpower steps right-hand tread plate (2), equally again left-hand tread plate (1) is lifted, alternately stepping of left and right pedal (1), (2), to left and right crank (3), (4) and axletree (5) produce unidirectional continuous rotation; The rotation of axletree (5) drives planetary wheel carrier (8) and rotates, the rotation of planetary wheel carrier (8) drives major planets wheel (9) or asteroid wheel (10) is done revolution and rotation simultaneously along internally toothed annulus (11), and the rotation of major planets wheel (9) or asteroid wheel (10) promotes center cone pulley (12) and rotates as speedup relative to axletree together with flywheel (13), wheel hub (14).
The utility model regulating mechanism is work like this, manual governing is removed the pulling steel rope, steel rope pulling shift fork (15), shift fork (15) are stirred internally toothed annulus (11) and are axially moved to right to major planets wheel (9) the increase transmitting ratio that is meshing with each other along guidepost (16), finish quick transmission; Manual governing is removed resetting, and spring (17) promotes internally toothed annulus (11) and axially moves to left to be meshing with each other to asteroid wheel (10) along guidepost (16) and reduce transmitting ratio, finishes transmission at a slow speed.
