Abstract

The invention relates to a leaf spring S-deformation bench test method comprising longitudinal torsion characteristic test and S-deformation fatigue test. A bench test device comprises a front support, a spring eye bracket, a test leaf spring assembly, a pad plate with a force arm, a pin shaft, a fork-shaped test force input shaft, a bearing, a rotating shaft, a lower pad plate, a U-shaped bolt, a rotating shaft bracket, a middle support, a back support, and a lifting eye bracket, wherein the front support is higher than the back support. The leaf spring S-deformation bench test mechanism of the invention can ensure the safety in the process of bench test. Test of different elasticity and different stiffness and fatigue test can be implemented. The test precision is high. The high front support and the low back support make the posture and force of the test leaf spring assembly consistent with those of finished automobile installation. The influence of torque generated when the test leaf spring assembly is twisted longitudinally or transversely on equipment is eliminated.

Description

technical field [0001] The invention belongs to the technical field of leaf spring detection and test equipment, in particular to a test method for a leaf spring S deformation bench. Background technique [0002] Leaf springs (referred to as leaf springs) can be placed vertically or horizontally on the car. The latter must be provided with an additional guiding force transmission device to transmit the longitudinal force, which makes the structure complex and the quality increased, so it is only used in a small number of light and miniature vehicles. Longitudinal leaf springs can transmit various forces and moments, have a guiding function, and have a simple structure, so they are widely used in automobiles. [0003] Longitudinal leaf springs are divided into symmetrical and asymmetrical. If the distance between the fixed center of the middle part of the leaf spring on the axle (bridge) (here the bolt is called the center bolt) and the center of the ears at both ends of th...
