Specific implementation mode
Referring to Fig.1, Fig. 2, a kind of belt transmission structure of two wheels battery-operated motor cycle, includes being driven by motor output shaft 8
Driving wheel 1, the driven wheel 2 being sleeved on trailing wheel input shaft 3 and around be located at driving wheel 1, the driving belt 4 on driven wheel 2.
Wherein, driving belt 4 uses gear band, driven wheel then to select toothed wheel, driving belt 4 and tooth form driving and driven
Wheel realizes transmission for engagement connection, therefore transmission efficiency higher, more accurate, can preferably transmit torque.
Further, since centre-to-centre spacing Q of the driven wheel respectively with output, between input shaft is concentric and driven wheel is equal to
It exports, the centre-to-centre spacing L of input shaft, tooth form driving belt 4 is set with directly on two driving wheels can be extremely difficult, first, tooth form passes
The material of dynamic belt 4 requires higher, and elasticity greatly weakens compared to V-shape belt, second is that three needs tooth form to agree with, needed for installation
Fit-up gap compare V-shape belt bigger.Therefore, it also needs further to be improved whole drive mechanism, improves driving belt 4
Assembly simplicity.
Specifically, input shaft 3 includes shaft body 31 and the engaging section 32 positioned at 31 one end of shaft body；Driven wheel 2 includes
The fixed plate 6 of the gear ring 5 and its outside that are assembled with driving belt 4；Gear ring 5 is equipped with aperture and is more than shaft body 31 and engaging section
The centre bore 51 of 32 contour dimensions makes assembling process middle gear circle 5 is eccentric to be set in shaft body 31, it is possible to provide assembly belt
Gap；Fixed plate 6 then be equipped with the pilot hole 61 coaxial with gear ring 5, pilot hole 61 engage with engaging section 32 connect realization from
The synchronous rotation of driving wheel 2 and input shaft 3.
It is the preferred embodiment of the utility model with reference to Fig. 3 to Fig. 5.
When assembly, first gear ring 5 is sleeved in the shaft body 31 of input shaft 3.It is set on axis since gear ring 5 is eccentric
On ontology 31, therefore gear ring 5 can be deviated toward 1 direction of driving wheel, and the centre-to-centre spacing Q between driven wheel is made to be less than output, enter
The centre-to-centre spacing L of axis, there is no need to pre-tighten easily be sleeved on centre-to-centre spacing with reference to the driving belt 4 that centre-to-centre spacing L is designed for raw footage
For on the driving wheel 1 and gear ring 5 of Q, assembly is light, more efficient.
After the suit for completing driving belt 4, first fixed plate 6 is assembled on 3 engaging sections 32 of input shaft；Again by gear ring 5
Toward input axis direction offset, until with fixed plate 6 to just and being bolted and being combined as driven wheel 2.Due to the dress of fixed plate 6
Distribution 61 and gear ring 5 are coaxial, and input shaft 3, the center of circle of gear ring 5 and fixed plate pilot hole 61 are on same axis at this time,
Centre-to-centre spacing Q i.e. between driven wheel is equal to the centre-to-centre spacing L of defeated inlet shaft and outlet shaft, is tensioning between feed belt and driven wheel
State meets the design calibration of drive mechanism.
When work, the output torque of driving shaft 6 is exported through driving belt 4 to driven wheel 2, and passes through fixed plate 5 thereon
Band driven input shaft 3 rotates, and eventually passes through reduction gear box and drives rear wheel, realizes good linear power output.
In addition to above-mentioned illustrated embodiment, the engaging section 32 on input shaft 3 can also be located relatively at the inside of shaft body 31, when assembly
First fixed plate 6 is connect with engaging section 32, then bias is inserted in gear ring 5 to realize driving belt 4 in the shaft body 31 of front end
Assembly, subsequently adjust that gear ring 5 is realized and the installation of fixed plate 6 is fixed again.
With reference to Fig. 6, centre bore 51 can be the circular hole or irregularly-shaped hole that diameter value is significantly greater than shaft body 31；With reference to Fig. 7, center
Hole 51 can also be the strip-shaped hole that 5 center of circle of gear ring is passed through in track, and the width of strip-shaped hole matches with 31 diameter value of shaft body, energy
Enough better ensure that the concentricity of driven wheel 2 and input shaft.
Strip-shaped hole can be various ways, and such as from center, straight line extends to form waist-shaped hole outward, or prolongs from center toward outside sweep
Length forms arc line shape hole, can realize the eccentric assembling of gear ring 5.Preferably, it is above-mentioned preferred reality that can make centre bore 51
The waist-shaped hole in example is applied, and the center of waist-shaped hole and gear ring 5 are concentric, turned without excessive when gear ring 5 is assemblied in input shaft 3
To adjustment, the offset adjusted of two-wheeled centre-to-centre spacing Q is more intuitive, rapid, and processing is also more convenient.
Further, fixed plate 6 is axially locked at by bolt on gear ring 5, and assembly is simple and convenient, such as the utility model
Fixed plate 6 be connected and fixed with gear ring 5 using three bolts, to meet torque by gear ring 5, fixed plate 6 to input shaft 3
Stablize output, also can suitably be increased or decreased under the premise of ensureing that the two connection is reliable according to the size of reality output torque
The quantity of bolt.
With reference to Fig. 8, further, pilot hole 61 is that spline is connect, and is equipped with ring in 32 both sides of engaging section with engaging section 32
Shape card slot 33, the fixed plate 6 are axially fixed in by snap ring 7 on engaging section 32, and connection structure intensity is high, torque transmission efficiency
It is more excellent.
The utility model engages realization transmission by driving belt with the tooth form of driven wheel, and transmission efficiency higher can
Torque is preferably transmitted, and driven wheel 2 is divided into gear ring 5 and fixed plate 6, is convenient for the assembly of driving belt 4, it is simple in structure
Rationally, efficiency of assembling is improved.
