The reinforcing part is located at the upper end of 1 of the right fixing holes, and because the right fixing hole is stressed more, the reinforcing part is added to increase the rigidity of the right fixing hole.
As the utility model discloses further improve, support bottom be equipped with downward convex circular depressed part, step portion, mounting hole, circular slot all be in concentric position. The stress of the concave part and the mounting hole is large, and after the concave part is arranged, the strength of the bottom of the support at the position of the circular groove can be increased.
The utility model has the advantages of this 3 part welding of left reinforcing plate, well hone lamella, right reinforcing plate constitute a whole on the support, the reason is: firstly, the 3 parts of the left reinforcing plate, the middle bone plate and the right reinforcing plate have simple structures, and the production and processing modes are simple and convenient; secondly, after the bracket is welded into the left reinforcing plate, the middle bone plate and the right reinforcing plate, the 3 parts can reinforce and reinforce the local area of the bracket; the left reinforcing plate can prevent the left side of the long groove from being easily enlarged or reduced in the distance between the long grooves; the middle bone plate can keep the round groove round all the time; the reinforcing ribs of the right reinforcing plate can increase the rigidity of the flat plate part, so that the flat plate part is not easy to warp and deform, and the right reinforcing plate can make the right side of the long groove not easy to increase or decrease the distance between the long grooves. The integral rigidity of the support can be obviously improved through the flanging at the upper end of the support, so that the thickness of the support can be thinner than that of the original support, the strength is better, and the manufacturing cost is finally reduced. The left fixing hole and the 2 right fixing holes are used for fixing part of parts of the automobile chassis. The mounting hole that is located the support bottom atress is great when in actual use, has then set up the upwards protruding step portion and has increased the intensity of mounting hole, and the step portion that upwards protrudes in addition is also for raising the high position of mounting hole.
