Embodiment Construction

[0012] The present invention will be further described below in conjunction with drawings and embodiments.

[0013] The detailed description and specific examples, provided below, indicate the preferred embodiment of the invention, but are for purposes of illustration only and are not intended to limit the scope of the invention.

[0014] exist figure 1 Among them, the gas spring 1 is completely sealed. When the vehicle load changes, the volume of the gas spring 1 must change accordingly. According to the ideal gas state equation under constant temperature

[0015] p×V n = const

[0016] The internal air pressure of the gas spring 1 also changes. When the vehicle load increases, the volume of the gas spring 1 decreases and the air pressure increases; when the vehicle load decreases, the volume of the gas spring 1 increases and the air pressure decreases.

[0017] Pneumatic variable current device 2 is made up of pneumatic variable displacement device 3 and sliding rheostat...

Abstract

The invention relates to a load-sensing variable-damping electromagnetic shock absorption system which mainly comprises a gas spring, a pneumatic variable-current device, a vehicle-mounted power supply, a switch and an electromagnetic shock absorber. Load of a vehicle directly influences gas pressure in the gas spring, gas in the gas spring is introduced into the pneumatic variable-current device by a gas pipe, and the pneumatic variable-current device can change field current of the electromagnetic shock absorber according to the magnitude of the gas pressure, so that a function of adjusting the damping characteristic of the shock absorber according to the load of the vehicle can be achieved. The shock absorption system is suitable for vehicles with a greater useful load variation, such as a miniature van vehicle and a light truck, and can allow the vehicles to perform self-adaptive damping control according to different working conditions such as no-load or full load, so that the good riding comfort and the driving safety of the vehicles can be obtained within a whole useful load range. Compared with an electric control suspension, the shock absorption system does not require a sensor or an electric control unit, and is low in cost and high in reliability.

Description

technical field [0001] The invention relates to a vehicle vibration damping system, in particular to a load-sensing variable damping electromagnetic vibration damping system, which can adjust the damping of the shock absorber according to the vehicle load without a control unit, and is suitable for air suspensions and effective load changes. large vehicles. Background technique [0002] The damping coefficient of the shock absorber in the traditional suspension system is generally a fixed value, which cannot meet the adjustment requirements of the damping coefficient of the shock absorber when the vehicle load changes, so it is difficult to achieve a satisfactory damping effect. The semi-active suspension developed rapidly in recent years can adjust the damping coefficient of the shock absorber in real time according to changes in vehicle driving conditions. However, due to its complex structure, slow response, high control system design requirements and reduced reliability,...
