Asymmetric inerter

Abstract

The invention provides an asymmetric inerter. The asymmetric inerter comprises a ball screw, a master gear, a flywheel, a reduction gear and a casing; the ball screw is mounted inside the casing; andan upper unidirectional rotator and a lower unidirectional rotator are mounted on the ball screw. The upper unidirectional rotator and the lower unidirectional rotator are opposite in forward rotationdirection, so that the flywheel has the different transmission ratios when connected with different structures to rotate, and the requirement that the inertance of the asymmetric inerter during compression stroke of a suspension is smaller than that of the asymmetric inerter during stretching stroke of the suspension is met.

Description

technical field [0001] The invention relates to the technical field of vehicle suspension structures, in particular to an asymmetric inerter. Background technique [0002] Suspension system is the general term for all force transmission connection devices between the frame of the car and the axle or wheels. As the main component of the vehicle, it forms the three main systems of vehicle vibration reduction together with tires and seats. As the most important damping system among the three, it plays a crucial role in determining the ride comfort, handling stability and ride comfort of the vehicle. [0003] The development of vehicle suspension has a history of nearly a hundred years. As the first typical suspension structure developed, the technology of traditional passive suspension is more mature than that of semi-active and active suspension. The traditional passive suspension, which is the core component, is still used today because it does not need a controller, has a s...

Problems solved by technology

In this patent, the change of the inertia coefficient needs to provide external control, resulting in additional energy loss, which does not meet the current development theme of green environmental protection

And to achieve the requirement that the inertia coefficient in the compression stroke is smaller than the inertia coefficient in the stretch stroke, it is necessary to use additional sensors such as stroke sensors for synchronous use, which virtually increases the cost of use.
