Driving axle type speed change manpower tricycle

The utility model belongs to the manual tricycle in the vehicle.

Existing manual tricycle the vehicle frame that railway carriage, steering hardware, vehicle seat and actuating device are housed by three wheel supports substantially and is formed, said actuating device is to be made of with the chain institute that is connected with small flywheel on being fixed on the drive wheel wheel hub the big gear wheel that is fixed on the axis, the manual tricycle of gear wheel, chain is housed, and in use existing can not speed change or can speed change and complex structure, chain and gear wheel are stretched and serious wear and problem such as load carrying ability is little, speed is low.

The purpose of this utility model is exactly in order to solve the problem of above-mentioned existence, but provide a kind of multi-change speed, wear-resistant, load carrying ability is big and fireballing manual tricycle.

Technical solution of the present utility model is to be fixed with the active plane gear on the axis of existing manual tricycle, on the drive wheel wheel hub, be fixed with driven face gear, between said active plane gear and said driven face gear, transmission shaft with a bearing supporting is connected to form actuating device, the splined driveshaft end is connected with the slippage cylindrical wheel that is meshed with said active plane gear and shift fork is housed, and the other end is fixed with the fixed cylinder gear that is meshed with said driven face gear, in order to substitute original gear wheel, the actuating device that chain constitutes.

Above-mentioned said manual tricycle can be the available man-power three-wheel vehicle; Said axis can be the axis that uses on the available man-power three-wheel vehicle; Said active plane gear is to adopt the gear ring that generating is processed into more than two roads to make at an end face of circular metal plate; Said driven face gear is to adopt generating to be processed into one gear ring at an end face of metal sheet to make; Said slippage cylindrical wheel and fixed cylinder gear are exactly common cylindrical wheel, and slippage cylindrical wheel one end should process groove, and shift fork is installed, and are connected with connecting rod and shifter bar on shift fork; Said transmission shaft is that an end processes spline and the slippage cylindrical wheel links, and the other end processes keyway and installs and fixes cylindrical wheel; Said bearing can be that plain bearing can be a ball bearing of main shaft also, is installed in transmission shaft two ends suitable position.Above-mentioned part is installed by accompanying drawing, can constitute the utility model.

The utility model is compared with existing manual tricycle, but has multi-change speed, long service life, an advantage such as load carrying ability is big and speed is fast.

Accompanying drawing is the utility model scheme drawing, and Fig. 1 and Fig. 2 are scheme drawing of the present utility model, and Fig. 3 is the A-A section, and Fig. 4 is the B-B section, in the accompanying drawing, 1 is the pedal leg, and 2 is the active plane gear, and 3 are the slippage cylindrical wheel, 4 is transmission shaft, and 5 is the fixed cylinder gear, and 6 is driven face gear, and 7 is drive wheel, 8 is vehicle frame, and 9 is shift fork, and 10 is connecting rod, and 11 is axis, 12 is the drive wheel wheel hub, and 13 is bearing, and 14 is vehicle seat, 15 is railway carriage, and 16 is steering hardware, and 17 is shifter bar.

The contriver once implemented the utility model.Be active plane gear 2 and the driven face gear 6 that No. 86104406 job operations described in the patent application specification process three road gear rings at first according to application number, job operation: (as shown in Figure 5).

At first select two conical gears (4) and (5) for use, the parameter of best two conical gears equates, conical gear (5) is contained in cylindrical wheel gear shifting machine (tooth 54 gear shifting machines, the Tianjin first machine tool works production) on the former clamp shaft (6), another conical gear (4) is contained in clamp shaft (3) last and vertical with conical gear (5) diaxon (β 90 degree) engagement.It is 200mm that one steel plate is processed into diameter, and thick is 10mm, at one end face (end face and axis normal, α 90 degree) be processed into the wide 8mm that is, height is the three road gear ring bases (as shown in Figure 5) of 6.5mm, and the distance between the gear ring base is 20mm, and plane gear ring base (2) is clipped on the clamp shaft (3).Select involute-type pinion cutter (1), its modulus is 2.5, and the number of teeth is 10, and cutter is thick to be 8mm.At this moment can start gear shifting machine, with pinion cutter (1) up and down reciprocatingly speed adjust to per minute 170 times, depth of cut 0.24mm, and make the pinion cutter (1) and the outmost turns gear ring base of plane teeth wheel blank (2) keep constant transmitting ratio, can feed processing outmost turns gear ring base.The outermost gear ring number of teeth is 76.Process the outmost turns gear ring, adjust the rotating speed of wheel blank (2), still make the second road gear ring base and the pinion cutter (1) of wheel blank (2) keep constant transmitting ratio, and the stroke of adjustment pinion cutter (1), make its cutting second road gear ring, and do not cut outer ring and inner lane gear ring, and at this moment can feed process the second road gear ring, the second road gear ring number of teeth is 54.With also can be with the gear ring machine-shaping of inner lane with quadrat method, the inner lane number of teeth be 32.Like this, face gear (2) is even if completion of processing.With castellated shaft 4 of prior art processing and cylindrical wheel 3 and 5, and slippage cylindrical wheel 3 and castellated shaft 4 are linked with running-fit, make the gear 3 can slippage on axle 4, cylindrical wheel 3 and 5 modulus elect 2.5 as, the number of teeth is 10, the facewidth is 8mm, and the cylindrical wheel 3 that is connected on the castellated shaft 4 is made the perpendicular engagement of its two axial lines with face gear 2, processes parts such as pedal leg 1, shift fork 9, axis 11, vehicle seat 14, railway carriage 15 again with prior art.Active plane gear 2 is fixed on the axis 11, driven face gear 6 is fixed on the wheel hub 12, the cylindrical wheel 5 that transmission shaft 4 other ends are fixing is meshed with driven face gear 6, and transmission shaft 4 is by bearing 13 supportings.And with reference to the accompanying drawings other parts are installed, can constitute the utility model.
