Which country is the Monroe shock absorber brand from?

[LeoMarie]

Monroe shock absorbers are a brand from the United States. Here is some related information about shock absorbers: 1. Purpose: To accelerate the attenuation of vibrations in the vehicle frame and body, thereby improving the ride smoothness (comfort) of the car, most vehicle suspension systems are equipped with shock absorbers. The car's shock absorption system consists of both springs and shock absorbers. Shock absorbers are not used to support the weight of the vehicle body but to suppress the oscillations from the spring's rebound after absorbing shocks and to absorb the energy from road impacts. 2. Principle: When there is relative movement between the vehicle frame (or body) and the axle due to vibrations, the piston inside the shock absorber moves up and down, causing the oil in the shock absorber chamber to repeatedly flow from one chamber to another through different pores. At this time, the friction between the pore walls and the oil, as well as the internal friction between the oil molecules, creates a damping force that converts the car's vibration energy into thermal energy of the oil, which is then absorbed by the shock absorber and dissipated into the atmosphere.
