Three of crank negative angle stop gear 9 structures are made of negative angle limiting device 94, referring to Figure 18; Described negative angle limiting device 94 comprises rubber case 941, stationary pipes 942, adapter plate 943, handle pipe 944 and hollow tubular 945; The front, left side of described adapter plate 943 is fixed with hollow tubular 945, rubber case 941 is enclosed within on the stationary pipes 942, and the boss of the pipe 942 that is fixed withstands, stationary pipes 942 is enclosed within the outside of hollow tubular 945, fix with screw, the back, right side of adapter plate 933 is connected with handle pipe 944, and handle pipe 944 is in screw is fixed on bottom tube 423.
When stretcher 15 was stepped on downwards, crank 14 was pressed on the rubber case 941 of stationary pipes 942 front ends, because the elasticity of rubber case 941, crank 14 is moved downward play the buffering inhibition, and it is stopped slowly.
When negative angle stop gear 9 was installed, the lower standing tube 416 in negative angle stop gear and the vehicle frame 4 was as follows with the relation of bottom tube 423:
1) if lower standing tube 416 is long, the negative angle limiting device is positioned at outside crank 14 slewing areas, and the negative angle limiting device will push up less than crank 14, can't control the crank slewing area, referring to Fig. 5 j.The length that should shorten lower standing tube 416 this moment makes bottom tube 423 rise to the b point by a point along lower standing tube 416, the b point should be positioned at chain guard 419 below, thereby make the negative angle limiting device can push up crank 14.Fig. 5 k is the figure after moving.
2) length of bottom tube 423 should make crank 14 can be pressed onto the push pipe head of crank negative angle stop gear 9; Referring to Figure 51.
In use, above-mentioned three kinds of negative angle stop gears 9 can be chosen any one kind of them.When riding stretcher 15, driving crank 14 rotates, axis 418 rotates under the effect of power-transfer clutch 6, when crank 14 arrives certain position, under the effect of negative angle stop gear 9, stop crank 14 further to rotate, and under the effect of crank recovery device 7, crank 14 is upwards returned, under the effect of positive angle stop gear 8, it is defined within the specific limits when upwards rotating, stops it to continue upwards to rotate.Repeat the fwd process then, form the up-and-down movement that moves in circles.
Conclusive effect to reaching the labour-saving purpose, is played in the position of center tap 415, now its effect is described below:
When riding stretcher, suppose direction perpendicular to ground, stretcher also is used on people's the pin with onesize masterpiece so, and direction is also perpendicular to ground, and this power produces moment to people's buttocks, and its arm of force is the distance of stretcher to buttocks.Because the people is sitting on the saddle, so this arm of force can be thought the distance of stretcher to the Z line.When stretcher was subjected to onesize power, the arm of force was big, and is also big to people's buttocks moment, and human body is that the used strength of its moment of balance is also big.The arm of force is little, and also little to people's buttocks moment, the strength that human body is used is also little.Be stretcher apart from the Z line when far away, step on difficultly, when the Z line is near, step on laborsaving.
Now playing 28 inches (710 millimeters) bicycles is example, and its center tap 415 is 1L (L is a crank length, below identical) apart from the distance of Z line, and when crank was positioned at the place ahead level attitude, stretcher was 1L+1L=2L apart from the distance of Z line.Center tap position range of the present invention is-0.3L≤D 1≤ 0.5L 1.3L≤H 1≤ 1.8L is with forward terminal: D 1=0.5L makes comparisons, and rides up and down because the present invention adopts in center tap the place ahead, so when crank also was positioned at level attitude, stretcher was 0.5L+1L=1.5L apart from the distance of Z line.When the stretcher of above-mentioned two positions was subjected to the power of identical size, the ratio of its moment was exactly the ratio of the arm of force, is 1.5L/2L=1.5/2=0.75=75%.
Because the size of people's strength not have the method for measuring, but by aforementioned, there is certain corresponding relation in the size of used strength and moment, thus also can think, when center tap 415 at D 1When=0.5L position and crank were positioned at level attitude, used strength was 75% of existing bicycle, and laborsaving in other words is 25%.
If want the labour-saving effect more greatly, desirable D 1=0.2L.When crank was positioned at level attitude, stretcher was 0.2L+1L=1.2L apart from the distance of Z line, with the ratio of the moment of existing bicycle be 1.2L/2L=0.6=60%.
If the scope of the rotational angle θ of both cranks all is-60 °≤θ≤60 °, then the ratio in the moment at the two-end-point place of scope is
(0.2L+1L*cos60°)/(1L+1L*cos60°)＝(0.2L+0.5L)/(1L+0.5L)＝0.7L/1.5/＝0.47＝47％
When crank was foot-operated up and down in ° scope of-60 °≤θ≤60, the scope of the ratio of both moments was 47%-60%, so the scope of the ratio of both used strength also is 47%-60%, the labour-saving scope is 40%-53%.Can find out the present invention's beneficial effect of pedal type bicycle up and down thus.
When center tap 415 is positioned at D 1=0.2L, if when crank is positioned at θ 〉=60 °, people's ankle place is crooked serious, at this moment step on not nature, not only out of reach labour-saving purpose may be felt hard on the contrary, so should be aided with the height of decline center tap, to relax ankle place degree of crook, desirable center tap height H 1=1.6L.So position D of center tap 1=0.2LH 1=1.6L can be preferred plan.
