Description

Pin-slot wheel set structure and vehicle

Technical Field

The utility model relates to a transmission structural design technical field especially relates to a vehicle of round pin grooved pulley group structure and applied this structure.

Background

The variable-speed transmission structure generally adopts gear set transmission, belt transmission, chain transmission and the like, takes a gear set as an example, and adopts a large gear and a small gear for meshing transmission, and the size of the transmission ratio depends on the number of teeth of the large gear and the small gear. This determines the amount of output power and the gear transmission has problems with wear during transmission.

Preferably, the ratio of the distance from the middle point of the bottom wall of the groove body on one side of the circle center of the bull wheel to the distance between the circle centers of the two round pins is

Preferably, the distance from the middle point of the bottom wall of the groove body towards the outer side of the circle center of the big wheel to the circle center of the big wheel is larger than or equal to the distance between the circle centers of the two round pins.

The utility model also provides a vehicle has adopted above the round pin grooved pulley group structure.

Adopt the utility model provides a pin slot wheelset structure adopts the pin slot structure to replace traditional gear drive, can realize laborsaving or economize the effect of merit equally, and when bull wheel and steamboat rotational speed equal, output can multiplicable 15%.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of the motion state of the present invention.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in figure 1, the pin-slot wheel set structure comprises a large wheel 1 and a small wheel 2, wherein the large wheel 1 and the small wheel 2 respectively use the circle center of the large wheel 1 and the circle center of the small wheel 2The center rotates as a rotating shaft, four groove bodies 3 are equally arranged on one surface of the large wheel 1 along the circumference, the groove bodies 3 are arranged towards radial parallel openings, two round pins 4 are equally arranged on one surface of the small wheel 2 along the circumference, the round pins 4 are matched with the inside of the groove bodies 3, the large wheel 1 drives one round pin 4 on the small wheel to move in the rotating process, and then the small wheel 2 is controlled to rotate. As shown in figure 1, the ratio of the distance from the midpoint A of the bottom wall of the groove body 3 on one side of the circle center of the big wheel 1 to the circle center B of the big wheel to the distance between the circle centers C, D of the two round pins 4 is as follows

In fig. 1, the proportional relationship between the line segment AB and the line segment CD can be calculated according to the pythagorean theorem, that is, the bottom wall midpoint a exactly coincides with the center of the circular pin 4, and when this condition is satisfied, the rotation state shown in fig. 1 is a critical state, that is, if the bull wheel 1 continues to rotate clockwise, the circular pin 4 above enters the tank body 3 and is driven by the tank body 3 to move to the lower right, and the circular pin 4 below is separated from the tank body 3 below, and the state diagram after the movement is shown in fig. 2. As can be seen from fig. 1, in practice, one of the grooves 3 rotates one turn, and the corresponding round pin 4 rotates two turns, i.e. the large wheel 1 rotates one turn, and the small wheel 2 rotates two turns. When the rotating speeds of the large wheel 1 and the small wheel 2 are equal, the output power can be increased by 15 percent.

The distance from the midpoint E of the bottom wall of the groove body 3 towards the outer side of the circle center of the bull wheel 1 to the circle center B of the bull wheel is larger than or equal to the distance between the circle centers C, D of the two round pins. As shown in fig. 2, it is easy to understand that the state at this time is to require the circle center of the round pin 4 to be still within the range of the outermost end (the end far from the circle center) of the slot body 3, so as to ensure that the transmission of the whole rotation is continuous.

The utility model discloses still provide and adopted above the vehicle of cotter way wheelset structure to the bicycle is the example, can adopt bull wheel 1 as the action wheel, through the running-board drive, steamboat 2 is as following the driving wheel, steamboat 2 passes through the chain and drives the flywheel, so can realize power transmission, bull wheel 1 drives steamboat 2 and can play the effect of province merit, and on the same hand, can adopt steamboat 2 as the action wheel, bull wheel 1 is as following the driving wheel, the bull wheel passes through the chain and drives the flywheel, can realize power transmission equally, steamboat 2 drives bull wheel 1 and can play the effect of province power. Similarly, taking an automobile as an example, the input shaft of the engine can be connected with the large wheel through a shaft, and then the small wheel is connected with the power output end through a shaft, so that power transmission can be realized. When the rotating speeds of the large wheel 1 and the small wheel 2 are equal, the output power can be increased by 15 percent.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
