The hydraulic rod in the trunk is disposable. If there is a problem, it is best to replace it as soon as possible, so as not to affect the normal use of the car and ensure the driving safety factor of the car.
The function of automobile hydraulic support rod is introduced as follows: the support rod is an elastic element with gas and liquid as working medium, which is composed of pressure pipe, piston, piston rod and several connectors, and is filled with high-pressure nitrogen. Because the piston has a through hole, the gas pressure at both ends of the piston is equal. Under the action of gas pressure, the pressure to the side with small cross-sectional area is generated, that is, the elastic force of the support rod. The elastic force can be set by setting different nitrogen pressures or piston rods with different diameters. Different from mechanical springs, support rods have nearly linear elastic curves.
