Abstract
The utility model relates to a boosting tricycle, which belongs to a jinrikisha provided with a gear assembly characterized in the meshing gear, comprising a gear box whose shaft direction is arranged under a handle and between two rear wheels. The gear box is crossed through by a pedal shaft and a rear wheel shaft; two groups of gears are fixed on the pedal shaft, the rear wheel shaft and the shaft arranged in parallel with the two shafts inside the gear box; the two groups of gears are linked by and composed of a chain wheel, a blocking wheel and the chains between the chain wheel and the blocking wheel arranged on the corresponding shaft end which extends outside of the same side of the gear box. By sufficiently making use of the pedal shaft and the rear wheel shaft, the utility model has the advantages of simple structure, small size, low cost and easy riding, so that we can even ride easily on the slope roads, providing with more ideal jinrikishas for the long distance and heavy loading transportation.
Description
A kind of power-assisted tricycle, relating to a kind of being equipped with engaging gear is the rickshaw of the gear system of characteristics.
At present, manual tricycle generally all is not provided with the transmission system that changes the rotatable parts rotating speed, so it is when having the travels down of certain slope, the bicyclist need pay bigger strength, particularly under the situation of load, often can not ride, push away just and can move ahead and need the people to take on handle.Chinese patent 92225198.3 provides a kind of manual tricycle transmission system, and it is mainly by three groups of pitch wheel groups, center tooth wheels and output gear, and gear gearshift and detent mechanism are formed.Though the device that this patent provides can be realized speed change, necessary first gear shift when travelling, location ability speed change bother during use, structurally it does not utilize the power of being used to of wheel fully, particularly when heavy lift transported at a distance, the bicyclist felt still that painstakingly this apparatus structure is also complicated.
The deficiency that the purpose of this utility model is to avoid above-mentioned prior art to exist, when a kind of travelling is provided as by bike, but the climbing of arbitrarily running is laborsaving, long service life, be beneficial to the remote defeated rickshaw far away of heavy duty.
The utility model is realized with following technical scheme: it comprise three-wheel vehicle and vehicle-mounted be the gear system that characteristics constitute by engaging gear.Gear drive is to step on axle and rear axle and parallelly cross its casing, sprocket wheel, gear wheel and chain therebetween that two groups of gears, two groups of gears settle on by the corresponding axle head that extends to the casing homonymy outside are installed respectively on being positioned at the axle of but stepping on axle and rear axle and setting in parallel of gear case body are linked and constitute by axially being installed in gear case between three-wheel vehicle handlebar below and trailing wheel and pin.Both sides and gear wheel are with the axle mounting flywheel outside gear case body.
The beneficial effect that the utility model had: because engaging gear has been installed on the car is the gear system that characteristics constitute, and has made full use of pin and step on axle and rear axle, and it is simple and reasonable for structure, and volume is little, cost is low.Because the reasonable disposition of each gear makes the three-wheel vehicle that gear system has been installed as bicycle, but arbitrarily running and have the ability of on the road of certain slope, riding easily, effortlessly, for the remote transportation of heavy burden provides desirable commuter vehicle tool.
Further specify the utility model below in conjunction with drawings and Examples.
Accompanying drawing is a power-assisted tricycle plan structure scheme drawing.
Accompanying drawing has provided the structural representation of a kind of most preferred embodiment of power-assisted tricycle, it by front-wheel 1, front fork 2, handlebar 3, pin step on 4, trailing wheel 9 constitutes the three-wheel vehicle main body, this figure has omitted crossbeam and vehicle seat.Gear case 5 axially is installed in 9 of handlebar 3 belows and trailing wheels, pin is stepped on 4 axle, parallel its casing 5 that crosses of the wheel shaft of trailing wheel 9, pin in casing 5 is stepped on 4, two groups of gears before and after the axle of rear axle and setting in parallel is provided with, they are mounted in pin and step on big gear wheel 10 on 4, big gear wheel 10 engagements are gone up the miniature gears of installing 11 with the axle that the axle that pin is climbed up parallels setting, miniature gears 11 drives coaxial big gear wheel 12, big gear wheel 12 engagements are stepped on axle with pin and are paralleled one group of gear cluster of miniature gears 13 compositions of installing on another root axle of setting, the installation shaft of miniature gears 13 extends to sprocket wheel 6 is installed on casing 5 external its axle heads, the axle that is paralleled setting by chain 7 interlocks with rear axle is gone up the gear wheel of installing 8, parallel with rear axle the gear wheel 8 of axle mounting of setting coaxial outside casing 5 both sides with axle mounting flywheel 16, miniature gears 15 is installed on this axle in casing 5, the big gear wheel 17 of installing on miniature gears 15 another parallel shafts of engagement, with big gear wheel 17 with axle mounting miniature gears 18, the big gear wheel 19 that miniature gears 18 engagements are installed on the rear axle is formed the backgear group and is constituted gear system, both sides are equipped with and are pressed case base 14 before and after on casing 5, the wheel of band retaining fork is housed in the inboard of gear wheel 8, it aims at fixed stop fork usefulness, but viscous motion gear wheel 8 when not travelling.Each big gear wheel in the casing 5 can adopt same size, and each miniature gears also can be selected for use unidimensional.The flywheel 16 that install casing 5 both sides can make three-wheel vehicle can fully use it in motion to be used to power, and it is free and relaxed that it is travelled, and as injecting external force, two groups of gear clusters rationally dispose before and after adding, and are laborsaving when riding.
Claims (2)
1, a kind of power-assisted tricycle, comprise gear system, it is characterized in that gear system steps on axle and parallel its casing that crosses of rear axle by axially being installed in three-wheel vehicle handlebar below with gear case and pin between trailing wheel, the pin that is positioned at gear case body is stepped on and two groups of gears, two groups of gears are installed respectively on the axle of axle, rear axle and setting in parallel are linked and constitute by extending to sprocket wheel, gear wheel and the chain therebetween installed respectively on the outer corresponding axle head of casing homonymy.
2, power-assisted tricycle according to claim 1 is characterized in that gear case, the outer both sides of its casing and gear wheel are coaxially installed with flywheel.
