The utility model has following good effect:
1, when making electricity consumption drive multifunctional power-assisted mode power-assisted, battery-driven car self need not installed electrical motor, and the dynamo-electric force aid system of this multifunctional power-assisted device can be as active force, and the assisted pedal stroke system is a power-assisted, also can allow the assisted pedal stroke system as active force, dynamo-electric force aid system is as power-assisted.Both make and ride easily quick, power saving, laborsaving under the power-assisted of shock-absorbing boosting system.When electricity drove multifunctional power-assisted mode and is used on bicycle, the three-wheel vehicle, both promptly became battery-driven car, effectively improve value of service and degree of utilization.
2, the assisted pedal stroke system is to be the power-assisted core with the pedal power axle, utilizes simple theory of machines that pedal system power-assisted speed is improved significantly; The pedal power axle changeed for 1 week, and large toothed disk drives wheel changeed for 10 weeks, and therefore, although the battery-driven car high-ball, the assisted pedal stroke process all can play strong impetus.
3, in the battery-driven car driving process, the assisted pedal stroke system can exist as power-assisted, also can Electronmotive Force be existed as power-assisted as power; The assisted pedal stroke system rides as power in the process, and under the power-assisted of the little electric weight of Electronmotive Force, its rider speed is followed one's inclinations, and can exceed the battery-driven car F-Zero, cuts easily fast, and power saving is laborsaving and help to trudge, and cuts effective prolongation Mechatronic Systems service life.
4, the multifunctional power-assisted device of this battery-driven car is because the needs of technology, and making pedal power axle and large toothed disk is the split linkage structure, the process or slide in the process so battery-driven car is ridden, the pedal power axle can stop operating at any time, also can rotate counterclockwise artificially, whole process is free and relaxed, does not have any resistance.
5, shock-absorbing boosting system, make full use of the natural force resource of the impulsive force that the bumper up-and-down movement produced, to greatest extent it is converted into power, and apply to effectively on the multifunctional power-assisted device, i.e. energy-conserving and environment-protective, economical and practical again, the every propelling of damping push rod 25mm, can make wheel change for 1.5 weeks, because power-assisted speed is fast, that is afraid of that small jolting also can be to rider with power-assisted.
6, in the battery-driven car driving process, the assisted pedal stroke system is power-assisted at any time, the shock-absorbing boosting system, and also power-assisted simultaneously, both can independent power-assisted also can stop power-assisted at any time, and whole process is switched smooth and easyly, is independent of each other.
7, when the multifunctional power-assisted device of A type is installed on electro-tricycle, bicycle, the manual tricycle, can be adjusted to assisted pedal stroke speed: the pedal power axle changes 1 all wheels and changes in 5 weeks, and this speed can guarantee to ride quality.
8, the battery-driven car of the multifunctional power-assisted device of A type is installed, the electronic product that electro-tricycle disposed, its power can suitably be reduced to half on former basis when design, can satisfy the rider needs.
9, the multifunctional power-assisted device design of this battery-driven car is small and exquisite, shows an interesting new approach, and is simple in structure, makes easily, has small investment, instant effect, the distinguishing feature that added value is high.
