Problems solved by technology

[0003] The traditional continuously variable transmission (CVT) is based on the main smooth conical disk / disk, and the slave disk moves on the surface of the main disk to realize the change of the transmission ratio (the main disk is changed), but the transmission of force is frictional force, and the switching range is wide. The switching time to achieve shifting is relatively long, resulting in low stability, small initial torque, and high cost of use, which cannot meet the existing shifting needs

Embodiment 1

[0039] Example 1: Combining Figure 1 to Figure 6 , install servo motor 13, screw mandrel 14, slide table 15 and guide rod 17 on bracket 19, slide table 15 is fixed on the screw rod 14 and guide rod 17, and one end of screw mandrel is connected with servo motor; Simultaneously on slide table Install the transmission motor 12, install the synchronous wheel on the output shaft, connect the synchronous wheel and the transmission motor through the synchronous belt 16, the transmission motor drives the output shaft to rotate through the synchronous belt, and the output shaft drives the driving gear to rotate; in this case, set the ring gear The number is four, respectively ring gear 1 2, ring gear 2 3, ring gear 3 4 and ring gear 4 5, set the width of ring gear 1 2, ring gear 2 3, ring gear 3 4, and ring gear 4 5 to 1cm and the interval between them is 0.1cm. When the circumference of ring gear 1 is determined to be 2*π*9.5=59.66cm, the transmission circles of ring gear 2 3, ring g...

Abstract

The invention discloses a parallel tooth sliding stepless speed change device. The speed change device comprises a gear ring mounting disc, a gear ring combination, an output shaft, a driving gear, an encoder and a control system, the gear ring combination is fixed on the gear ring mounting disc, the gear ring combination is formed by combining a plurality of gear rings, gaps are arranged among the gear rings, one to a plurality of speed change points are arranged on the gear rings, teeth of the gear ring at the position of the speed change points are parallel teeth, and tooth grooves of the parallel teeth of the gear rings at the position of the same speed change point are on the same straight line. Through switching of the driving gear between the gear rings, different transmission ratios are achieved, and sliding stepless speed change between parallel teeth of the gear rings is achieved.

Description

technical field [0001] The invention relates to a parallel gear sliding continuously variable transmission device. Background technique [0002] Continuously variable transmission is a type of automatic transmission, which refers to a transmission system that can continuously obtain any transmission ratio within the transmission range. The best match between the drive train and the engine operating conditions can be obtained through continuously variable transmission. Common continuously variable transmissions include hydromechanical continuously variable transmission, metal belt continuously variable transmission (VDT-CVT) and variable slope continuously variable transmission. [0003] The traditional continuously variable transmission (CVT) is based on the main smooth conical disk / disk, and the slave disk moves on the surface of the main disk to realize the change of the transmission ratio (the main disk is changed), but the transmission of force is frictional force, and ...
