Description
Technical field
The utility model belongs to auto parts and components field, especially relates to a kind of brace panel being applicable to Rear secondary frame for vehicle lower plate.
Background technology
Suspension is the general name of all force transmission connections between the vehicle frame of automobile and vehicle bridge or wheel, its effect transmits the power that acts between wheel and vehicle frame and power is turned round, and buffering is passed to the impulsive force of vehicle frame or vehicle body by uneven road surface, and the vibrations caused thus that decay, to ensure that automobile can smoothly travel.Rear secondary frame for vehicle can regard the skeleton of rear axle as, is the component part of rear axle.The effect of Rear secondary frame for vehicle is used to supporting rear axle and rear-mounted support, promotes rear-mounted globality, avoids rear-mounted and rear axle to be rigidly connected, and also has simultaneously and intercepts the effect that vibration & noise directly enters compartment.
Usually use now the Rear secondary frame for vehicle of one " mouth " font, the lower plate of existing Rear secondary frame for vehicle can be subject to the distortion action of side direction external force in turning process, and the junction of corner lacks strengthens fixing fender guard, is easy to occur fracture, the problem of disconnection.
Summary of the invention
In view of this, the utility model is intended to propose a kind of brace panel being applicable to Rear secondary frame for vehicle lower plate, plays reinforcement fixation by being closely welded in Rear secondary frame for vehicle lower plate, promotes globality and the stability of Rear secondary frame for vehicle lower plate, effectively reduces vibrations and noise.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of brace panel being applicable to Rear secondary frame for vehicle lower plate, comprise base plate, upper hem and lower hem, described base plate, described upper hem and described lower hem are by one-body molded after off-chip, swaging and punching by the thick steel plate of 2.5mm, described base plate is provided with the groove striking out arc surfaced depression, the upper and lower of described groove floor respectively has a through hole for being connected with Rear secondary frame for vehicle lower plate, described upper hem and described lower hem bend all left, and described upper hem and described lower hem are all provided with many reinforced ribs of up/down perforation distribution.
Further, the nadir of the cambered surface depression of described groove and the angle of vertical direction are 27.5 °.
Further, the described upper hem bent left and the angle of horizontal direction are 77 °.
Further, the described lower hem bent left and the angle of horizontal direction are 73.8 °.
Further, the outside face of described base plate, described upper hem and described lower hem is provided with zinc rete.
Relative to prior art, the brace panel being applicable to Rear secondary frame for vehicle lower plate described in the utility model has following advantage:
(1) the utility model consists of base plate integrated after off-chip, swaging and punching, upper hem and lower hem the steel plate that 2.5mm is thick, there is higher mechanical strength, durable, and the integrated mode of production effectively can reduce defect ware, and the efficiency of production is higher; Upper hem and lower hem are welded on the correspondence position of Rear secondary frame for vehicle lower plate, base plate carries out fastening by screw through the through hole that the groove of its arc has, ensure that the utility model can be combined with Rear secondary frame for vehicle lower plate closely, play and strengthen fixing and promote the globality of Rear secondary frame for vehicle lower plate and the effect of stability; Compared with the straight structure without groove in traditional brace panel, on base plate of the present utility model, the groove of arc more can be fitted Rear secondary frame for vehicle lower plate, in conjunction with tightr; The upper hem bent left and lower hem effective minimizing in automobile turning process acts on lateral force in Rear secondary frame for vehicle lower plate, and contribute to distortion action to minimize, not rupturing in available protecting Rear secondary frame for vehicle lower plate four corner junctions, does not disconnect; Many reinforced ribs of the up/down perforation distribution that upper hem and lower hem are provided with, can protect upper hem and lower hem not to rupture when longitudinal stress, the mechanical strength of lifting itself; Having benefited from the utility model strengthens fixing to Rear secondary frame for vehicle lower plate, and automobile is more stable in the process travelled, and greatly reduces vibrations and noise imports compartment into.
(2) nadir of the cambered surface depression of the groove of base plate of the present utility model and the angle of vertical direction are 27.5 °, the upper hem bent left and the angle of horizontal direction are 77 °, the lower hem bent left and the angle of horizontal direction are 73.8 °, through test of many times detection validation, these angles can play reinforcement fastening effect to Rear secondary frame for vehicle lower plate, and can reduce the best setting acting on lateral force in Rear secondary frame for vehicle lower plate when turning; One deck zinc rete that surface of the present utility model is coated with, plays anti-wear, the effect of rust protection, more durable.
