Torque buffering device capable of being elastically compressed by multiple circles for mechanical transmission

Abstract

Disclosed is a torque buffering device capable of being elastically compressed by multiple circles for mechanical transmission. Spiral grooves are formed in a spiral groove disc; the outer circle of a force transmission spring is mounted on the inner circle of the spiral groove disc. The right side of a spring inner circle mounting shaft corresponds to the middle of a right spring inner circle force transmission groove plate, and the left side of the spring inner ring mounting shaft corresponds to the middle of a left spring inner ring force transmission groove plate. Torque transmission pin shaft fixing plates are arranged at the two ends of a sliding force transmission block supporting pin shaft. The parts, at the end of the sliding force transmission block supporting pin shaft, of a spring inner circle force transmission pin shaft are in strip-shaped grooves formed in the two sides of the right spring inner circle force transmission groove plate and the left spring inner circle force transmission groove plate and are fixed at the outer side ends of the right spring inner circle force transmission groove plate and the left spring inner circle force transmission groove plate through a connecting plate of the spring inner ring force transmission groove plates. A torque transmission pin shaft penetrates through the spiral grooves. According to the torque buffering device, a gear can be shifted smoothly in a short time while buffering can be achieved, and the torque buffering device is suitable for speed-changing gear shifting of an electric automobile and an internal combustion engine automobile.

Problems solved by technology

[0002] After the car starts, when the first gear is shifted to the second gear, the occupants often feel a sense of frustration, especially when taking a city bus. This is due to a The shock is caused by the large change of transmission ratio between the second gear and the second gear. For vehicles equipped with manual transmission and hydraulic torque converter, neither the shock absorber nor the hydraulic torque converter can alleviate the impact well. In addition to causing discomfort to the occupants, It also causes a short-term high torque value in the drive train, which will impact the gears, drive shafts and other control components in the drive train, which will intensify the wear of the components, and even cause the teeth or drive shaft to break

Considering this impact in the design, it is necessary to increase the safety factor, which will increase the size of the gear and transmission shaft or require a special thermal processing process, resulting in an increase in component weight and cost.
