A kind of car carrier leaf spring suspension matching method

Abstract

A method for selecting that leaf spring suspension of a car comprises the following steps: 1, preparing a suspension bracket, wherein the suspension bracket comprise a moving mechanism and a fixing mechanism which moves together with the moving mechanism, wherein an adjusting device for fixing the leaf spring of car is arranged on the fixing mechanism; 2, establishing a floating device, wherein that floating device is fil with a buoyant liquid, a sensing module is arranged inside the buoyant liquid, a floating ball with a density smaller than the buoyant liquid is arrange inside the buoyant liquid, and the floating ball contacts with the regulating device and drives the regulating device to move up and down; 3, fixing that leaf spring of the car in the regulating device, pressing down according to the gravity of the leaf spr, driving the floating ball to move toward the lower part of the liquid level, and transmitting the detection information of the initial height and the real-time height of the liquid level to the control end by using the sensing module. The invention can quickly select and match the car conveyor leaf spring, has high selection accuracy, and improves the selection efficiency of the car conveyor leaf spring.

Description

technical field

[0001] The invention relates to the technical field of car parts selection and matching, in particular to a method for selecting and matching leaf spring suspension of a car carrier. Background technique

[0002] Leaf spring, referred to as leaf spring, is a leaf spring composed of no less than one piece of spring steel. Leaf springs are commonly used in wheel vehicle suspensions, originally called laminated or bracket springs, sometimes called semi-elliptical or trolley springs, and are one of the oldest forms of springs. When the leaf spring is installed in the automobile suspension and the vertical load it bears is positive, each spring leaf is deformed by force and has a tendency to arch upward. At this time, the axle and frame are close to each other. As the axle and frame move away from each other, the positive vertical load and deflection experienced by the leaf springs gradually decreases, and sometimes even reverses.
