Description

Shaft type DC driver

The utility model is to disclose a kind of current Electrical Bicycle second generation driver train, laborsaving, the efficient innovation of vehicles such as the driver train of battery-driven car, battery-operated motor cycle and common bicycle, three-wheel vehicle, cripple's car.

Electrical Bicycle in the market, motor bike mechanism complexity, the stupid amount of body is heavy, the price height, and motor bike and self-propelled vehicle also have environmental pollution, ordinary bicycle, three-wheel vehicle and cripple's car are the old patterns that has continued last 100 years, and upward slope is put forth one's strength, contrary wind is required great effort, long road is painstaking.

The purpose of this utility model is that the driving engine of dessert machine motor-car and motor bike is a power with the electricity driving, for exploitation battery-driven car, battery-operated motor cycle new product lay the foundation.Be to promote the Electrical Bicycle industrial expansion and alleviate people's physical labor intensity, and project organization gathers, volume is little, in light weight, efficient is high, cost is low, easy for installation, practicality is big, popularization is wide shaft type dc driver.

The utility model is to be that power and oscillating tooth fluctuation novel transmission mechanism serves as to drive two parts of output to form with the most novel high-efficiency energy-saving permanent magnet disc DC motor of the eighties, shaft type and two kinds of forms of back shaft type before can being divided into, have high, medium and low and a plurality of kinds of infinite speed variation, the high or low power plurality of specifications;

The utility model compact conformation, volume are little, shaft type and back shaft type actuator before on the position of the forward and backward wheel hub of motor bike, installing respectively, supply with 24 overhead accumulator power supplys, saved driving engine and driving engine supporting parts and a whole set of reduction gearing mechanism in addition, simplified vehicle structure greatly, alleviate weight, reduced cost, moulding attractive in appearance, saved the energy, do not pollute, raise the efficiency more than 60%, and had the off-road capability that single driving and front and back wheel drive simultaneously.

Under the situation that the front fork and the Vee formation frame of Electrical Bicycle need not to change, just can install, bigger aluminum alloy gear case of current Electrical Bicycle volume and step-by-step variable gear and axle have been saved, overcome the shortcoming of present volume cart height, make whole vehicle body can shorten tens centimeters, saved material, alleviated weight, vehicle moulding attractive in appearance has reduced cost; Function still has pedal and electric dual-purpose, and climb 15 degree and speed are by raising the efficiency more than 5 percent under the conditions such as relevant department's regulation.

Bicycle, three-wheel vehicle and cripple's car etc. need not changed other parts under the situation that keeps original foot-operated function, as long as the rotating shaft one cover mechanism of original front vehicle wheel is taken off, shaft type dc driver before changing, connect 24 overhead accumulator power supplys, just become the pedal and electric motor moped, people have also improved efficient with regard to not worried against the wind driving, upward slope, the road is long and goods is heavy painstaking problem.

The utility model structure is an end with the permanent-magnet disk DC motor, and oscillating tooth fluctuation transmission is the other end, is closely as one mutually, formed that volume is little, compact conformation overall.Motor permanent magnet can be divided into two kinds of versions of single or double, is fixed on the inner end surface of an outer side or is fixed on the outer and inner both ends of the surface epitrochanterian commutator machine outer face.Power supply also enters in same end by brush.Axle sleeve is fixed on the interior circle of rotor, drives the eccentric rotation of being furnished with balance iron, produces eccentric shock wave, drives the oscillating tooth of radial peg shape.The pin tooth is contained on the pinwheel frame, is fixed on the electric motor end cap outer face jointly, and has the center of gravity supporting mechanism.One-level oscillating tooth dish and as the eccentric of double reduction, carries out eccentric shock wave after finishing one-level and slowing down, also be furnished with balance iron; Carry out double reduction.The pinwheel of double reduction is common pinwheel and the pinwheel frame that one-level is slowed down.Behind the double reduction, secondary oscillating tooth dish reaches the design desired speed, and the outer end cap direct connection drives shell, drives.

Accompanying drawing: eccentric shock wave device (3) balance iron (4) brush of (1) power lead (2) axle sleeve, brush carrier, eccentric shock wave device (15) oscillating tooth dish (16) the balance iron of brush holder (5) commutator (6) permanent magnet (7) casing (8) rotor (9) shell (10) electric motor end cap (11) pin braces (12) pin tooth (13) oscillating tooth (14) oscillating tooth dish (17) lid end (18) axle.

The utility model is tested at motorcycle, reached starting performance good, can the load-carrying 120 kg, 60 kilometers of maximum speeds/time, climbing is good greater than 20 °, the 40 kilometers/flexible cross-country ability of spending, travel of energy consumption.

Test at electric bicycle and bicycle, reached starting performance good, the climbing 15 °. Noise is low, speed is pressed 20 kilometers of traffic department's regulations/time, 50 kilometers/degree of energy consumption, the light and flexible of travelling is subjected to expert's favorable comment.
