Inertial container device with continuously-adjustable inertia coefficient

Abstract

The invention provides an inertial container device with a continuously-adjustable inertia coefficient. The inertial container device comprises a driving wheel, a driven wheel, a gear, a rack / flywheel / hydraulic pump, a driving wheel hydraulic control cylinder and a driven wheel hydraulic control cylinder, wherein a V-shaped groove is formed between the movable part and the fixed part of the driving wheel; the gear is arranged on a driving shaft, and is meshed with the rack; a V-shaped groove is formed between the movable part and the fixed part of the driven wheel; the flywheel is arranged on a driven shaft; the driven wheel is driven by an elastic metal belt arranged in the two V-shaped grooves; the movable parts of the driving wheel and the driven wheel are driven by the driving wheel hydraulic control cylinder and the driven wheel hydraulic control cylinder which are connected with a hydraulic pump respectively. The engagement radius of the metal belt is adjusted through axial movement of the movable part of the driving wheel and the movable part of the driven wheel, so that the transmission ratio between the driving wheel and the driven wheel is adjusted, and continuous adjustment of the inertia coefficient is realized.

Description

technical field [0001] The invention relates to an inerter device with continuously adjustable inertia coefficient. Background technique [0002] SMITH, a scholar at the University of Cambridge, proposed the idea of ​​an inerter and designed a rack and pinion inerter and a ball screw inerter, realizing a strict correspondence between mechanical and electronic networks and promoting the development of mechanical networks. A suspension network is realized with three components of spring, damper and inertial container, which further improves the overall performance of the vehicle. [0003] Chinese patent 200810123830.8 discloses a rack and pinion inerter, which is a real two-terminal element like a spring and a damper. The rack and pinion inerter is composed of a box body, a flywheel, a pinion shaft A, a bull gear, a pinion shaft B and a rack. The rack is meshed with the pinion shaft B, the bull gear is coaxially connected with the pinion shaft B and meshed with the pinion sh...

AI Technical Summary

Problems solved by technology

[0004] Because the rack and pinion inerter adopts a homogeneous flywheel, its own weight is relatively large, and its inertial coefficient cannot be changed once it is designed. There are not enough inerters with variable inertial coefficients that can be applied to active suspension and semi-active suspension. attention and research and development, and the energy of the flywheel rotation in the inerter device has not been effectively utilized
