AI Technical Summary

Problems solved by technology

But the actual situation is: more than five gears (forward gears) of the stepped transmission will make the structure greatly complicated, and the operating mechanism will also be correspondingly complicated.
The most widely used manual stepped transmission needs to cooperate with the clutch to shift gears frequently during use, which consumes a lot of physical strength for the driver, and requires certain operating skills and experience, which is very inconvenient to use

Abstract

The invention discloses a reducing transmission wheel and relative transmission device. Wherein, said transmission device is formed by a reducing transmission wheel, a middle transmission band, and relative shifter; the wheel drawing band is winded to form the working surface of reducing transmission wheel, while the non-transmission part is winded in the wheel center; the wheel drawing band and the transmission wheel transmit torque via the drawing support that radial moving on the transmission disk; the position of drawing support decides the nodal circle radius of transmission wheel; the reducing wheel via amplifying wheel device and the reducing wheel device realize the change of transmission nodal circle; said transmission device utilizes the change of nodal circle radius to shift the speed. The invention can be used in vehicle.

Description

technical field [0001] The invention relates to mechanical transmission, in particular to a transmission wheel capable of changing the radius of the wheel and a transmission mechanism using the wheel. Background technique [0002] The transmission plays a very important role in the process of transmitting the power of the prime mover to the working machine. Take automobiles as an example: the engine with the same power is the most suitable for the power requirements of the automobile, but in fact, the internal combustion engine with small size and high efficiency is commonly used, and the internal combustion engine must be equipped with a transmission to overcome the defect of its own characteristic curve. [0003] Relevant automobile research theories show that: to make the automobile engine emit the maximum power at any speed, the transmission ratio i g It should change with the vehicle speed according to the following formula: i g =0.377rn p / i 0 u a . (where r is t...
