Abstract

The present invention provides a rear axle beam. The rear axle beam is made of a plate with the thickness being less than or equal to 4mm. The cross section of the middle segment of the rear axle beam is in the shape of a semicircle, and the inner diameter of the semicircle is greater than the thickness of the plate. According to the rear axle beam, on the basis of increasing the space curvature, the structure in which the strength is controlled segmentally is adopted, and the cross sections of the middle segment and the two ends of the rear axle beam are independently optimally designed, so that stress of each part of the rear axle beam is effectively controlled and decreased, the space curvature tendency is guaranteed and the movement clearance is met.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a rear axle beam, which is especially suitable for reducing the stress of the torsion beam rear axle opening section and the space bending beam body. Background technique [0002] In the automotive field, in order to reduce the manufacturing cost, the rear axle beam of the current torsion beam usually adopts open section and non-high-strength steel, and the static stress of the beam body is required to be lower than 600MPa. [0003] figure 1 It is the bottom view of the traditional rear axle beam. figure 2 Rear view of conventional rear axle beam. image 3 A top view of a conventional rear axle beam. Such as Figure 1 to Figure 3 As shown, in order to meet the above requirements, the thickness of the beam steel plate in the past usually has to be 4 mm or more, and the rear bridge beam 10 is mostly straight or only slightly curved upward in the middle. The rear axle beam 10 is ben...
