Automobile torsion bar springs are spring-loaded parts that utilize the torsional elastic deformation of the rod and are widely used in automobiles, trains, tanks and armored vehicles. Quenching is an important process for processing torsion bar springs. Today's manufacturers usually use conventional quenching. The disadvantages are: easy to cause torsion bar bending, uneven hardness, fatigue resistance, and large amount of slack. The author combines his own practical experience in the work, and uses the rolling calibration value quenching aids to solve this kind of problem well. It is hereby proposed for your reference. 1. Analysis of the current situation of torsion bar spring quenching process The torsion bar spring structure of the car is a straight rod with one end fixed and a torsional load (ie, subjected to torsional stress) at the other end. The torsion bar can be divided into two types: solid torsion bar and hollow torsion bar. The cross section has circular, square, rectangular, elliptical and polygonal shapes, and the circular section is mostly used. The most common use is this paper. Compared with coil springs and leaf springs, torsion bar springs have a simple structure, no friction during operation, stable spring characteristics, no chattering, large energy storage per unit volume, small spring volume, and are small and lightweight products. It is widely used in automobiles, trains, tanks and armored vehicles. The torsion bar in the car is also very large. The torsion bar is bent into a bow or frame shape to reduce the tilt or lateral swing of the car body, and the suspension car can be improved. Braking performance and occupant comfort.
