Movable teeth automatic speed variator

Abstract

An automatic transmission of an oscillating teeth gear comprises an input shaft fixed on a shell, an output shaft fixed on the shell, and a compound intermediate body moving mechanism, which crosses with the input shaft and the output shaft. The transmission is characterized in that a pair of annular bodies to contain the oscillating teeth gears are assembled symmetrically at two ends of an intermediate shaft of the compound intermediate body via a bearing and a bolt; returning plates of the oscillating teeth gears are arranged on the intermediate body respectively and cross with a moving part mechanism on the intermediate shaft, which is equipped with a screw rod and a slide rail; stack gear plates are arranged at the internal ends of shells of the input shaft and the output shaft to form an angle of 5 to 20 degrees with the middle oscillating teeth gear surface of the annular bodies, and partly contact with the middle oscillating teeth gear surface; when straight teeth on the stack gear plate meet with the oscillating teeth on the annular bodies, the appropriate tooth space is formed, the annular bodies are driven to move radially along cone elements of the stack gear plates, and the intermediate body is driven to move straightly and repeatedly, so the number of straight teeth on the stack gear plates, which mesh alternately with oscillating teeth in the annular plates, is changed to realize the function of transmission. The transmission is provided with the advantages of the low cost, the simple structure, the big torque, the convenience for maintenance and control, the high reliability, and so on.

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.
