Coaxial and co-cylindrical multistage positive and negative rotation transmission method and transmission utilizing same

Abstract

A coaxial and co-cylindrical multistage positive and negative rotation transmission method comprises multistage gear engagement rotation transmission consisting of a driving wheel, a plurality of driven wheels and multistage auxiliary gear banks, the driving wheel is provided with two side gears, each driven wheel is provided with two side gears, the driven wheels are coaxially serially connected with the driving wheel, and the multistage auxiliary gear banks are uniformly distributed between the driving wheel and each driven wheel and between each two driven wheels, are respectively engaged with the side gears of the driving wheel and the driven wheels, and are provided with input auxiliary gears and output auxiliary gears. The coaxial and co-cylindrical multistage positive and negative rotation transmission method is characterized in that the side inner gear or the side outer gear of the driving wheel is engaged with the power input auxiliary gears so that rotation power is transmitted to the power input auxiliary gears, the power input auxiliary gears transmit the rotation power to the power output auxiliary gears via connecting shafts, and the power output auxiliary gears are engaged with the side inner gears or the side outer gears of the driven wheels so that the rotation power is transmitted to the driven wheels. The invention further provides a coaxial and co-cylindrical multistage positive and negative rotation transmission.

Description

technical field [0001] The invention relates to a coaxial and co-cylindrical multi-stage forward and reverse speed change method and its device. It is suitable for various mechanisms that need speed change and speed regulation, such as speed change devices for various vehicles, gearboxes for lathes, etc., and belongs to the technology of speed changers and gears. field of transmission technology. Background technique [0002] Most of the transmission devices of modern mechanical transmissions use gearboxes to install gears of different sizes and diameters on the same shaft to form different gears with different linear speeds of external gears to achieve speed change. This structure takes up a large space and the linear speed of each external gear Different output power gears have different diameters, which makes the gear clutch mechanism meshed with it complicated. The complex speed change mechanism and complex clutch mechanism are not only large in size, high in quality, a...

[0002] Most of the speed change devices of modern mechanical transmissions use gearboxes to install gears of different sizes and diameters on the same shaft to form different gears with different external gear linear speeds to achieve speed change. This structure takes up a large space and the linear speed of each external gear Different output power gears have different diameters, which makes the gear clutch mechanism meshed with it complicated. The complex speed change mechanism and complex clutch mechanism are not only large in size, high in quality, and high in production cost, but also have a high impact on moving vehicles. Space and weight also consume a lot of energy to the vehicle. Therefore, how to reduce the volume and weight of the transmission mechanism, improve the efficiency of the transmission mechanism, and make the clutch mechanism simple and efficient, and the movement track of the clutch device simple and convenient, is a key issue in today's automobile industry. An urgent need in the developed age! In particular, how to make the transmission system of the automatic transmission mechanism of an automatic transmission vehicle simpler and more reliable, with fewer circuit control points, fewer hydraulically controlled transmissions, small size, light weight, low cost, low energy consumption and fuel saving. The development and popularization of the automobile industry is extremely important! However, in almost all types of automobiles and various speed changer fields, no speed change mechanism that can meet the above requirements has been found.
