Wheel with inertial accumulator

Abstract

The invention provides a wheel with an inertial accumulator. The wheel comprises the inertial accumulator, a wheel rim and a tyre; the tyre is mounted on the wheel rim, the inertial accumulator comprises an oil bag, metal spiral pipes, pistons and cylinder barrels, each cylinder barrel is arranged between adjacent spokes, the pistons are located in the cylinder barrels to divide the cylinder barrels into nitrogen cavities and oil liquid cavities, the metal spiral pipes are tightly arranged on the outer surfaces of the cylinder barrels in a wound mode, one end of each metal spiral pipe is communicated with the oil liquid cavity of each cylinder barrel, the other end of each metal spiral pipe is communicated with the oil bag, and the oil bag is arranged on an outer circle of the wheel rim. By means of the wheel, resonance in the high-frequency section ranging from 10-15 Hz of the wheel can be inhibited, driving smoothness and driving safety of an automobile are improved, the defects that a power absorption isolator increases unsprung mass, and it is difficult to coordinate the suspension work range are overcome, and the problem that a passive terrace damping vibration isolation system is complex in structure and difficult to arrange is solved.

Description

technical field [0001] The invention relates to a wheel, in particular to a wheel with an inertia accumulator. Background technique [0002] Wheels are usually composed of rims, spokes and tires, which are important components for supporting the vehicle and alleviating road impact, and also affect the ride comfort and driving safety of the vehicle. The dynamic characteristics of traditional wheels when they generate high-frequency resonance in the range of 10-15Hz have a great influence on the ride comfort of the vehicle and the grounding performance of the wheels. [0003] The document "Performance Analysis of Automobile Suspension Equipped with Dynamic Vibration Absorber" can improve the severe vibration of wheels and vehicle body at high frequency to a certain extent. A vehicle suspension disclosed in the literature uses springs and mass blocks to absorb wheel vibration energy in the form of absorbing vibrator, but absorbing wheel vibration energy in this form requires a...
