A stepless automatic gearbox with toothed active rod

Abstract

The invention relates to a gear-toothed rod stepless automatic transmission, which comprises a first bracket, a second bracket, two input discs, two output discs, a second transmission shaft, a first transmission shaft, a first transmission gear, a second Two transmission gears; two input disks are respectively installed on both sides of the first bracket; two output disks are connected with the second bracket through the first transmission shaft, and are respectively installed on both sides of the second bracket; the disk surfaces of the input disk and the output disk There are multiple sector rack areas; one end of the second transmission shaft is connected to the first bracket, and the other end is connected to the second bracket. The first transmission gear is slidably installed on the second transmission shaft and connected to the two input The racks of the discs mesh with each other, and the second transmission gear is slidably mounted on the second transmission shaft and intermeshes with the racks of the two output discs. The gear-tooth movable rod stepless automatic transmission of the invention has high power transmission stability and can transmit relatively large power loads.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of gearboxes, and in particular, to a gear-tooth movable rod continuously variable automatic gearbox. Background technique [0002] As the most common means of transportation in modern society - automobiles bring great convenience to people's travel. However, regardless of the fuel type of the car, automatic transmission (AT), manual transmission (MT) and dual clutch transmission (DSG / DCT) are used, and power transmission needs to be interrupted during the shifting process. On the one hand, this shifting method will Frustration, on the other hand, can also cause energy loss. [0003] Continuously variable transmission (CVT) can solve the above problems. It can maintain the continuity of power transmission during the speed change process, realize the best match between the drive train and engine operating conditions, and has high operating efficiency and low fuel consumption. However, t...

However, regardless of the fuel type of the car, automatic transmission (AT), manual transmission (MT) and dual clutch transmission (DSG / DCT) are used, and power transmission needs to be interrupted during the shifting process. On the one hand, this shifting method will Frustration, on the other hand, can also cause energy loss

[0003] Continuously variable transmission (CVT) can solve the above problems. It can maintain the continuity of power transmission during the speed change process, realize the best match between the drive train and engine operating conditions, and has high operating efficiency and low fuel consumption. However, the continuously variable transmission (CVT) ) is easy to slip and generate heat, so the transmission power is unstable, resulting in waste of power, and the conveyor belt is easily damaged
