Description
Technical Field
The invention relates to the technical field of reduction boxes, in particular to an integrated rim gear reduction transmission system for electric friction.
Background
The existing transmission system for the electric motorcycle products, the speed reduction system of the electric motorcycle products circulated in the market is usually single-stage or double-stage, wherein the single-stage speed reduction system is usually direct belt pulley (chain wheel) speed reduction, and the double-stage speed reduction system specifically comprises: firstly, reducing the speed of a belt pulley (chain wheel), and then reducing the speed of a parallel shaft gear to a rim; the parallel shaft gear is firstly decelerated, and then the belt pulley (chain wheel) is decelerated to the rim.
The disadvantages of the single reduction system are: the transmission ratio is not large, the torque on the wheel is insufficient, and under the condition of the same torque on the wheel, the driving motor can only be designed with large torque and low rotating speed, so that the high-efficiency design target of the motor is not met. The conventional design speed ratio is 5: 1 or so, because the small pulley has the minimum restriction, the large pulley is difficult to be made large.
The disadvantages of the double-stage deceleration system are:
the first method comprises the following steps: the problem that the velocity ratio is little can be solved to earlier belt (sprocket) transmission back parallel gear speed reduction, this transmission system, nevertheless produces other shortcomings simultaneously, and parallel shaft gear need fix on reduction gear casing, and this cover system will be installed on the casing that a replacement chain stay (left side) was used, and opposite side (right side) also need install with the chain stay substitute simultaneously, and what just can stabilize installs on the electric motorcycle frame, guarantees its reliability, but other shortcomings also can appear simultaneously:
because the mounting point of the shell (the speed reducer and the driving motor) is a fixed position, but the center distance needs to be adjusted in belt transmission, a set of complex belt adjusting device needs to be added to the whole transmission system, and the product cost and the complexity of the system are greatly increased.
When the tire assembly is replaced, the bottom fork (right side) and the auxiliary part (such as a disc brake system) need to be detached, so that the tire assembly can be detached, and the maintenance cost is greatly increased.
And the second method comprises the following steps: the transmission system can solve the defects of the transmission system after gear reduction and then belt transmission, but other defects can also occur:
the gear reducer is installed at the output end of the driving motor, so that the axial length of the driving motor is increased, and the arrangement of a transmission system is not facilitated.
After the driving motor is provided with the speed reducer, the output torque is increased simultaneously, so that the torque transmitted by the belt (chain wheel) is larger, the damage risk of the belt (chain wheel) is increased or the belt (chain wheel) with a larger specification is required, and the cost is increased invisibly.
