With Figure 10 is example: will be from driven wheel (17) and axle drive shaft (18) and antifriction-bearing box (18-1) and bearing inner ring fixed cover (19-5), be enclosed within on the axle drive shaft (18), with said method multiplying wheels at different levels,, be assembled to support frame one by one and get on until terminal miniature gears and rear vehicle shaft.Concrete assembly technology route and method of operation are: during assembling with the placement of the Width of gear wheel shaft bracing frame, even the plane parallel of circular port is in the placement of horizontal surface perpendicular to horizontal surface.Axle drive shaft (18) is assembled to the small end hole from big end, promptly go into the corresponding aperture of gear case from the borehole jack of longitudinal beam (1-4), enter the longitudinal beam (1-4) of framework when axle after, to connect chain link (17-1) packs on the axle, at this moment driven wheel (17) is inserted on the axle of connecting key (17-1) position, use the cover subpad of semi-circular hole during assembling between driven wheel (17) and support frame (1-3), the height of cover is the series of combination part, can be designed to highly be 1mm, 2mm, 5mm, 10mm, the serial special-purpose semicircle cover of 20mm, the internal diameter of semicircle cover is equal to or greater than the diameter of the big end of gear wheel shaft, after being inserted in gear on the axle, filling up first circular cover knocks gear wheel shaft with rubber hammer an axle band key is entered in the bore, determine bearing inner ring fixed cover (19-5) and the front and back position relation of gear on axle according to Figure 10, carry out assembling gear and bearing inner ring fixed cover (19-5), can finish the assembling of gear so smoothly.With the above-mentioned same method assembling second stage and even final stage gear and gear wheel shaft.When needing dismounting and above-mentioned assembly technique carry out reverse operation and get final product, behind the dismounting tightening screw, be disassembled gear below fill up first circular cover, knock the small end of gear wheel shaft with rubber hammer, just can dismantle any one-level multiplying wheel.Gear wheel shaft and gear setting-up procedure can begin assembling from any one-level multiplying wheel.Workshop-trained man can one man operation.Not too skilled assembler should the assembling of two people's compounding practices.Running in bearings and bearing seat again after the gear of axle drive shaft (18) and terminal rear vehicle shaft installs.After gear and gear wheel shaft all installed, just the lower house on the assembling gear case then assembled connecting rod chute guide rail (11), refills the handle of writing music for a song (16), then assembles connecting rod (15), refilled after the assembling bench and joined rear wheel.After finishing this step, then assemble braking brake parts and generator component, then assemble the front vehicle wheel parts, circuit and the light fixture and the instrument and meter of whole circuit is installed afterwards, circuit-line specifically walk line position, the scene is joined and is done boring and install.After finishing the installation of circuit and electrical equipment, mounting teeth roller box lower house (1-1), after the gear case lower house installs, blow off dust miscellaneous material in the gear box casing and between the gear with pressurized air, clean gear and gear box casing with oil, behind the Ex-all waste oil, load onto clean lubricating oil, assembling gear case upper shell (1-2) and sealing gear case.Assemble whole car case.When installing test run, test run debugging vehicle frame being raise makes the back face wheel unsettled, and the speed mileometer normal operation is determined in the debugging brake, after the brake normal operation, just can make the test run of contacting to earth of back face wheel! Test run must slowly be travelled and put on a safety helmet.Must be chosen in during test run on the playground of school and carry out, determine that the brake working condition is good, determine the speed mileometer normal operation, grasp and be familiar with setting out on a journey again after the performance and travelled.Lay special stress on: " fork of running at high speed drives the body-building labour-saving bicycle " when travelling, must normally just can travel by speed mileometer, because have only mileage meter to know just that accurately moving velocity is no more than the moving velocity of national regulation restriction.The method of this car limited speed is passable once being to use the people only need slowly mark time to travel, for speed does not transfinite, and the setting of also can slowing down.The method of deceleration speed limit is: be single-wheel " fork of running at high speed drives the body-building labour-saving bicycle " 1, for rear wheel, and can be hinge wheel and minor sprocket transposition assembling; No doubt the endoporus of hinge wheel and minor sprocket need be done corresponding change.Also can suitably reduce the diameter of rear wheel, the so-called qualification that suitably reduces the diameter of rear wheel is: the diameter of rear wheel must be greater than the height of gear case, otherwise gear case can contact to earth, and can not travel.For rear wheel is two-wheel " fork of running at high speed drive body-building labour-saving bicycle " as for the figure (2), the 9th grade of multiplying wheel (27) and terminal Drive pinion (28) position are exchanged, just reach and slowed down 2.8 times speed limit effect, no doubt miniature gears (28) and being connected of gear wheel shaft must be changed into antifriction-bearing box and connect, the 9th grade of multiplying wheel (27) with change the key connection being connected of rear vehicle shaft into., but best method for limiting speed is slowly to mark time to travel not carry out the speed limit setting.Under the good situation of road conditions, can run at high speed.All necessarily keep safety first firmly in mind no matter how to travel, obey the regulation of " law on road traffic safety " of country.
This car safety traffic rule:
1, before each long-distance running and after using certain hour, must the check brakes drg reliable operation whether, the method of checking can make brake actuator work earlier, just drive then and advance, advance if can not drive, illustrate that then brake actuator is working properly, just can set out on a journey and travel otherwise must overhaul brake actuator.
2, before each long-distance running and after using certain hour, must check whether gear case and bearing have lubricating oil,, also will damage gear during the gear dry friction owing to be to run at high speed, will burn out a bearing during the bearing dry friction.
3, in running at high speed, if when running into the horizontal strong wind on the left side or the right side, because car load is not heavy, people's standing position is foot-operated travels because need satisfy again, so the car load case is promptly higher to the aspect ratio of car case end face from plane on the gear case, need be greater than or equal to 1700mm, so must open left and right sides car door, avoid strong wind that car is blown and turn over.If preferably halt when running into especially big storm, once had Xinjiang of China somewhere strong wind train to be blown the report that turns over.
4, turning indicator and side-marker lamp, stoplight stop lamp must keep in good condition.
When 5, speed ratio was big at that time, turn radius can not be too little, and negotiation of bends speed can not be fast, because the flipper turn centnifugal force is too big, overturn in the side easily.
