Q:How should we choose the spring material?: In the small spring should be used after hardening spring steel wire, cold drawn steel wire and lead bath oil tempered steel wire with high strength and good surface quality, fatigue performance is higher than the ordinary tempered steel wire, simple processing, good manufacturability, quality and stability.

Q:What are the categories of springs?: Linear springs, linear springs from top to bottom of the thickness and density unchanged, the elasticity coefficient for fixed values. The dynamic response of spring of this design can make the vehicle obtain more stable and linear, is conducive to better control the vehicle driver, for vehicle performance orientation and competitive disadvantages of vehicles is of course affect comfort.

Q:Is the car short spring good?: Hello! General short spring is not short, but also hard, short effect is to reduce the body, lower center of gravity, hard role is to reduce the body tilt in vehicle cornering, turn faster. The disadvantage is that the chassis is low, through the poor sex, easy to drag the site, hard on the comfort of the.

Q:Buffer spring buffer for automobile: With abrasion resistance, cold resistance, impact resistance, aging resistance, water resistance, service life of 2 - 3 years. First, use Jack to support the body and clean the spring with water. After the installation is complete, the automobile damping buffer rotating around a few times, check whether the spring into full spring slot; the outer edge is rub the fender buffer; buffer overlap or not. Also, in order to avoid the shock absorber, when the vehicle is moving down to the bottom of the spring, it is necessary to install a stop card.

Q:What is spring pressure and height?: Press the compression spring to the point where each circle is tight. Press it and press it high

Q:Stainless steel and spring steel hardness, who is hard?: Hardness is checked by indentation, not by pliers.Stainless steel, of course

Q:What are the main functions of spring?: Measure the magnitude of forces, such as springs, scales, and springs in a dynamometer

Q:How to choose spring steel material?: Spring steel is selected on the basis of the section size of the spring, such as high carbon steel 65, suitable for production in the spring of 12 ~ 15mm under section 60CrMnA, suitable for the production of spring and the car less than 50mm in diameter with heavy-duty spring. The 30W4Cr2VA is used to make heat-resistant spring for work below 500 degrees centigrade. Generally, hot forming springs are generally quenched and tempered at moderate temperature to obtain a structure with a maximum elastic limit and fatigue properties

Q:Hydraulic diagram of the one-way valve has two kinds of drawing, with a spring, without a spring, what is the difference between automatic reset function is not? Without a spring, it will not be repeated: Certain large diameter one-way valves have no springs, and steel balls rely on gravity return. These valves usually require vertical mounting.In fact, in the oil flow driven, the ball will always reset, no spring one-way valve can also be closed. Only the closing action has hysteresis, better than the spring back reliable.

Q:In short, in vibration and wave, it is not easy to make mistakes when we grasp the difference and relationship between "displacement" and "displacement relative to the balance position": In short, in vibration and wave, it is not easy to make mistakes when we grasp the difference and relationship between "displacement" and "displacement relative to the balance position"
