Embodiment 1

[0108] provides a figure 1 The shown double-track double-needle torque aspirator is suitable for a torque transmission system with a torque variation period of 360°. The track surface is the inner surface of the track ring, and the needle tails of the two spring pins are coaxially arranged with the track through the needle hub. And the needle tips of the two spring pins are in contact with the track surfaces of the two tracks respectively; the torque suction and discharge shaft is connected to the needle hub, and in the process of driving the spring pins to rotate, the needle tips of the two spring pins are respectively driven along their respective track surfaces. Sliding or rolling, and due to the variable diameter setting of the track, the expansion and contraction of the spring needle can be realized, and then the torque work can be sucked and exhaled in the radial direction.

Embodiment 2

[0110] provides a figure 2 The shown double-track double-needle torque aspirator is suitable for a torque transmission system with a torque variation period of 360°. The track surface is the inner surface of the track ring, and the needle tails of the two spring needles face each other and are narrowed to only the needle ring. The needle hubs are connected together, the needle hub and the track are coaxially arranged, and the needle tips of the spring needles with branch needle tips respectively abut against the branch track surfaces on both sides, while the needle tips of the spring needles without branch needle tips It is in contact with the middle track surface in the middle; the torque suction shaft is connected with the needle ring, and in the process of driving the needle ring to rotate, the needle tip of the spring needle actively slides or rolls along the track surface, and is set due to the diameter change of the track. , to realize the expansion and contraction of t...

Embodiment 3

[0112] provides a image 3 The shown double-track double-needle torque aspirator is suitable for a torque transmission system with a torque variation period of 360°. The track surface is the outer surface of the track ring, and the needle tails of the two spring pins are respectively fixedly connected to the outside of the track, and On the inner surface of the needle loop coaxially arranged with the track, two elastic needles are arranged oppositely, and the needle tips of the elastic needles with branched needle tips respectively abut against the branch track surfaces on both sides, while the elastic needles without branched needle tips The needle tip of the needle is in contact with the middle track surface in the middle; the torque suction shaft drives the track to rotate through the connection with the track, so that the needle tip of the spring needle passively slides or rolls along the track surface, and due to the change of the track The radial setting realizes the exp...

Abstract

The invention discloses an n-track n-needle type torque sucker, which comprises: a plurality of tracks arranged coaxially; the multiple tracks are arranged according to 360° / n equal rotation angles with reference to the track surface of the track, and n It is a natural number not less than 2, which is the number of tracks; the track surface is a cylindrical surface or other curved surface formed by a variable-diameter rotation, and does not have rotational symmetry; the spring needle is set corresponding to the number of tracks, and the The spring pins are arranged at 360° / n equal rotation angles and installed coaxially or on the same cylindrical surface; the spring pins are retractable components and are arranged along the radial direction of the track; the needle tips of the spring pins are in contact with the track surface; among them, the track One of the two pins is fixed on the torque suction and suction shaft in a manner that follows the torque suction and suction shaft, and the other is fixed. It controls the expansion and contraction of the spring needle through the cooperation of the spring needle and the track surface, and realizes the instantaneous contradiction between the power supply and the load demand through the spring needle expansion and contraction, that is, it gives the torque transmission the ability to cut peaks and fill valleys as needed.

Description

technical field [0001] The invention relates to the technical field of mechanical energy saving, in particular to an n-track n-needle type torque aspirator. Background technique [0002] Torque (or torque) transmission is one of the basic forms of mechanical power transmission, and power, load and shaft are the three basic elements of torque transmission. Generally speaking, power and load have their own intrinsic torsional characteristics, but their intrinsic torsional characteristics often do not match, resulting in mixed torque transmission, accompanied by the reduction of the power and load's own energy conversion efficiency, torsional shock , torsional energy transfer loss, shortened device life and reduced reliability. [0003] For the torque matching problem of load and power, traditional technologies have given various solutions, but a simple and thorough solution is still lacking. For example, in terms of automobiles, existing solutions include increasing the numb...
