Hydraulic energy-storing flywheel swing and oscillation absorber

Abstract

The invention relates to a hydraulic energy-storing flywheel swing and oscillation absorber using the hydraulic damping, the rigidity of a hydraulic energy storer and the inertia of a flywheel. The hydraulic energy-storing flywheel swing and oscillation absorber mainly comprises a flywheel, a hydraulic motor, a valve, a hydraulic energy storer, a hydraulic cylinder and a swinging rod, etc. The equivalent rotating inertia which is much more than the actual rotating inertia of the flywheel can be generated on the swinging and oscillating end under the driving and the amplifying action. The flywheel isolates the low-frequency swing and oscillation through storing and releasing the kinetic energy; the hydraulic energy storer isolates the high-frequency swing and oscillation through storing and releasing the potential energy; the hydraulic damping has the function of consuming the swing energy and the oscillation energy; and the flywheel, the hydraulic energy storer and the hydraulic damping can together buffer and absorb the swing and the oscillation at all frequency bands. The hydraulic energy-storing flywheel swing and oscillation absorber with simple structure can absorb the swing and the oscillation by storing and releasing the energy, has light weight and can save power and energy, give out less heat and reduce swing and oscillation frequency band width.

Description

technical field [0001] The invention relates to a shock absorber, which is a shimmy shock absorber which utilizes hydraulic damping, hydraulic accumulator stiffness and flywheel inertia to act together. Background technique [0002] Shimmy vibration is a common form of vibration, and shimmy problems often affect the handling and application of structural systems. For example, when a car is running, due to the violent swing of the steering wheel from side to side, it often causes the steering wheel to snap. In severe cases, the driver may not be able to control the steering wheel. Moreover, the shimmy of the steering wheel of the car will reduce the comfort of the ride, increase the driver's fatigue, and cause abnormal wear of the tires, which may easily cause damage to related parts. [0003] In order to reduce the adverse effects of shimmy, some designs use pneumatic or hydraulic damping shock absorbers. For example, Chinese patent 03804190.1 has invented a kind of motorc...

Problems solved by technology

However, the existing hydraulic vibration reduction method mainly adopts energy consumption and vibration reduction, that is, the hydraulic damping effect is used to consume the energy of the shimmy vibration, and the kinetic energy of the shimmy vibration is converted into heat energy and other energy forms to be dissipated.

On the one hand, this wastes the power of the drive, on the other hand, it will cause other adverse effects due to the heating of the structure.
