Movable teeth automatic speed variator

Abstract

The movable tooth automatic transmission includes an input shaft fixed on the casing, an output shaft and a composite intermediate body intersecting the input shaft and the output shaft, and is characterized in that the two ends of the intermediate shaft of the composite intermediate body are connected by a pair of bearings and bolts to accommodate the movable teeth. The annular body of the tooth is assembled symmetrically. The movable tooth reset plate is respectively installed on the intermediate body, and the lead screw and slide rail are installed crossing the intermediate shaft. The surface is set at an angle of 5°~20°, and there is partial contact; when the straight teeth of the stacked toothed plate meet the movable teeth on the annular body, a suitable tooth groove is formed; the intermediate body can be connected with the input shaft and output shaft at both ends. The shaft moves back and forth crosswise, and drives the annular body at both ends to move radially along the conical generatrix of the stacked toothed disc, thereby changing the number of straight teeth on the stacked toothed disc alternately meshing with the movable teeth in the annular body to realize the function of speed change. It has the advantages of low cost, simple structure, large torque, convenient maintenance and control, and high reliability.

Description

technical field [0001] The invention relates to an automatic transmission, in particular to an automatic transmission with movable teeth. Background technique [0002] The use of automatic transmissions in automobiles has the advantages of easy operation, comfortable driving, and the ability to reduce driver fatigue, and has become a development direction for modern car configurations. A car equipped with an automatic transmission can automatically change speed and torque according to road conditions, and the driver can concentrate on the road traffic without being disturbed by shifting gears. [0003] The existing automatic transmission mainly has the following forms: AT (automatic torque converter transmission), CVT (mechanical continuously variable automatic transmission), AMT (electrically controlled mechanical automatic transmission). [0004] AT (Torque Converter Automatic Transmission) is widely used in mid-to-high-end cars due to its high precision and perfect contr...

Problems solved by technology

The main problem now is that the shifting accuracy is not high, the shock feeling when shifting is too obvious, the power is interrupted, the driving is uncomfortable, the technology is not mature enough, etc.
