Abstract
The utility model relates to a device for changing the speed of a man-power tricycle, which is used for the man-power tricycle. The device makes use of chain wheels with key grooves in a plurality of holes with different diameter sizes on a drive shaft to control the key groove to independently work, which reaches the goal of speed change. A driving wheel (1) rotates and drives a driven wheel (2) and a drive shaft (3) to rotate by a chain. When speed is changed, a spring (6) and a pull cord (7) control the position movement of a sliding key (4); thus, when the projection of the sliding key (4) enters the key groove of the chain wheel (5), the chain wheel (5) rotates and drives a corresponding fly wheel (8) and a shaft (9) of the tricycle to rotate; when the projection of the sliding key (4) enters the groove of the chain wheel (5) with a small diameter, the tricycle is in the state of low speed. When the projection of the sliding key (4) enters the groove of the chain wheel (5) with a big diameter, the tricycle is in the state of high speed. Thus, the man-power tricycle with different speeds can be realized, which obtains the effect of labor saving.
Description
The utility model is used for manual tricycle, is to change the device of going into power three-wheel vehicle speed.
Manual tricycle is very general on the market now, using very extensively, all is a speed, and a speed is unaccommodated as transport vehicle, because speed difference, the moment of transmission is also different, and the three-wheel vehicle of a speed is imperfect, and people's strength is in different size, road conditions is different, have smooth, have rugged, upward slope is arranged, descending is arranged, three-wheel vehicle itself has empty wagons, loaded vehicle is arranged, velocity adaptive not various change condition requirements.
The purpose of this utility model provides a kind of device that can satisfy various change condition requirements.The manual tricycle of a speed is designed to multistage speed.
The purpose of this utility model is achieved in that on three-wheel vehicle the sprocket wheel of pedal is a driving wheel.Middle by chain, link with follower on the transmission system, follower is installed on the transmission shaft of transmission system, and the sprocket wheel that keyway is arranged in the different holes of diameter is housed on transmission shaft, and its can freely rotate.Slide key and spring are housed in transmission shaft.Slide key is done reciprocal slip by the effect of backguy and spring in transmission shaft.When the projection of slide key enters in the keyway of that sprocket wheel, that sprocket wheel is work just.The two couples together flywheel on sprocket wheel on the transmission system transmission shaft and the three-wheel axletree by chain, and that sprocket rotation on transmission shaft is with the just rotation of flywheel on its corresponding three-wheel axletree.Because the sprocket diameter on the transmission shaft varies in size, so the rotating speed that passes on the three-wheel axletree is also different, thereby obtains different speed.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
The section-drawing of the manual tricycle step by-step variable gear that Fig. 1 .2 basis the utility model proposes and K are to figure.
Following structure and the service condition that proposes concrete device according to utility model that describe in detail in conjunction with figure.
This apparatus structure is by the driving wheel (1) of pedal on the three-wheel vehicle, the follower on the transmission system (2), and transmission shaft (3), slide key (4), sprocket wheel (5), spring (6), the flywheel (8) on backguy (7) and the three-wheel axletree, three-wheel axletree (9) is formed.
Driving wheel (1) is contained on the axis of three-wheel vehicle, is driven by the manpower pedal.Follower (2) is fixed on the transmission shaft (3) of transmission system, couples together by chain with driving wheel (1).Transmission shaft (3) is main of transmission system, along with follower (2) rotates together.Slide key (4) is contained in the groove of transmission shaft (3), under the effect of spring (6) and backguy (7), slides in groove.Diameter has the sprocket wheel (5) of keyway to be contained in transmission shaft (3) outside in the different holes, controls each sprocket wheel (5) by the projection on the slide key (4) and works independently.Spring (6) is contained in the middle part of transmission shaft (3), and right-hand member withstands on the position, right angle of slide key (4), the effect that slide key (4) is resetted.Backguy (7) is contained in the transmission system left end, and combines with slide key (4), hauls slide key (4) shift position.Flywheel (8) is fixed on the three-wheel axletree (9), and that sprocket wheel (5) on transmission system rotates, and drives corresponding flywheel (8) by chain and rotates, so three-wheel axletree (9) is also along with rotation.Three-wheel axletree (9) rotates, and has just driven the three-wheel vehicle walking.
During work,, drive follower (2) and transmission shaft (3) rotation by chain by driving wheel (1) rotation of pedal.During speed change, by the shift position of spring (6) and backguy (7) control slide key (4).When the projection of slide key (4) enters in that sprocket wheel (5) keyway, that sprocket wheel (5) just rotates.That sprocket wheel (5) that rotates drives corresponding flywheel (8) by chain again and rotates, and flywheel (8) is fixed on the three-wheel axletree (9), so three-wheel axletree (9) is just along with rotation.If the projection of slide key (4) enters in the little sprocket wheel of diameter (5) keyway, is low speed.When the projection of slide key (4) enters in the big sprocket wheel of diameter (5) keyway one is at a high speed.Like this, just obtained different speed.
Claims (4)
1, manual tricycle step by-step variable gear, this device has a transmission shaft (3) that slide key (4) and spring (6) are housed in its inside, and left end has backguy (7), it is characterized in that on the transmission shaft (3), the sprocket wheel (5) that keyway is arranged in the different holes of diameter is housed, controls by slide key (4).
2, device according to claim 1, at the fixing follower (2) of the right-hand member of transmission shaft (3), the driving wheel (1) by pedal on chain and the three-wheel vehicle axis is connected.
3, device according to claim 1 has the sprocket wheel (5) of keyway in the different holes of diameter are equipped with in the outside of transmission shaft (3), be connected with flywheel (8) on the three-wheel axletree (9) by chain.
4, device according to claim 1, spring (6) is contained in the middle part of transmission shaft (3), and right-hand member withstands on slide key (4) position, right angle, and the left end that backguy (7) is contained in transmission system combines with slide key (4).
