Problems solved by technology

For example, at low speed, let the gear pair with large transmission ratio work, and at high speed, let the gear pair with small transmission ratio work. In the past, three shafts were connected through different gear pairs to achieve the speed change function, and the structure was complicated. Difficult to disassemble and assemble, and generally have oil leakage and other phenomena, high working noise and low reliability

Abstract

The invention provides an automatic transmission. Two one-way bearings are arranged on a spindle, the first one-way bearing is directly connected with a belt pulley, the second one-way bearing is connected with the belt pulley through a planetary gear transmission mechanism, and the planetary gear transmission mechanism functions in changing transmission ratio, so that good speed changing effects can be achieved. The automatic transmission is simple and compact in structure, convenient in maintenance, disassembly and assembly, low in working noise, less in oil leakage and convenient to clean.

Description

technical field [0001] The invention relates to a transmission, in particular to an automatic transmission with compact structure, low noise and convenient assembly and disassembly. Background technique [0002] A transmission is a device used to change the speed or traction of machines such as machine tools, automobiles, and tractors. It consists of many gears with different diameters and is usually installed between the driving shaft and the driven shaft of the engine. The mechanical gearbox mainly applies the deceleration principle of gear transmission. Simply put, there are multiple sets of gear pairs with different transmission ratios in the gearbox, and the shifting behavior when the car is running is to make different gear pairs in the gearbox work through the operating mechanism. For example, at low speed, let the gear pair with large transmission ratio work, and at high speed, let the gear pair with small transmission ratio work. In the past, three shafts were conn...
