Multi-power radial direct drive regulated metal toothed belt type automotive continuously variable transmission

Abstract

The invention belongs to the field of automobiles, and relates to a metal-toothed belt-type automotive continuously variable transmission with multi-power radial direct drive adjustment, which includes a driving wheel, a metal belt, a driven wheel and an intermediate speed reducer; the driving wheel drives the driven wheel through the metal belt Rotation, the power output end of the driven wheel is connected to the intermediate reducer; the structure of the driving wheel and the driven wheel is the same; the driving wheel includes a drive shaft, a first turntable, a second turntable, a radial moving device, a beam, and a movable tooth module; the first turntable 1. The second turntable is arranged on the transmission shaft; the crossbeam is arranged between the first turntable and the second turntable, and the two ends of the crossbeam can move on the first turntable and the second turntable along the predetermined trajectory; the radial movement device is arranged on the transmission shaft and located between the first turntable and the second turntable, the radial movement device can drive multiple crossbeams to approach or move away from the transmission shaft synchronously; the movable tooth module is arranged on the crossbeam, and the movable tooth module is engaged with the metal belt. The invention has the advantages of compact structure, high bearing capacity and high transmission efficiency.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a metal-toothed belt-type continuously variable transmission for automobiles with multi-power radial direct drive adjustment. Background technique [0002] As a bridge between the engine power input and the vehicle load, the transmission occupies an important position in the vehicle design. At present, the transmission methods for automobiles mainly include manual transmission MT, hydraulic automatic transmission AT, continuously variable transmission CVT, dual-clutch transmission DSG, etc. Among them, the most widely used continuously variable transmission is the metal belt continuously variable transmission. [0003] see figure 1 , metal belt continuously variable transmission consists of engine flywheel 1, starting clutch 2, driving wheel hydraulic control cylinder 30, driving wheel 40, hydraulic pump 50, driven wheel hydraulic control cylinder 60, driven wheel 70, firs...
