Abstract
The invention discloses a bent arm. The bent arm comprises a straight rod part and an arc-shaped arm part which are integrally forged and formed; one end of the arc-shaped arm part is connected to the straight rod part; a first boring end part is arranged at the other end of the arc-shaped arm part; a second boring end part is bulged and formed in the middle of the arc-shaped arm part; and a boring axis of the first boring end part is parallel to the boring axis of the second boring end part. The bent arm according to the technical scheme has the advantages of reasonable structure, convenience in processing and manufacturing, reliable usage, high cost performance, and the like.
Description
Technical field
The present invention relates to a kind of car chassis parts, relate in particular to a kind of curved boom.
Background technology
The chassis effect is supporting, installation automotive engine and each parts thereof, assembly, forms the moulded of automobile, and accepts the power of driving engine, makes automobile produce motion, guarantees cruising.The chassis is made up of transmission system, running device, steering system and brake system four parts.The curved boom forging is one of safety component of automobile, realizes carrying and guide function, and the running environment of in the vehicle ' process, working complicacy is born complicated reverse stress, and is high to the requirements for quality of curved boom parts.
Summary of the invention
In order to solve above-mentioned technical matters, the purpose of this invention is to provide a kind of curved boom, have rational in infrastructure, make things convenient for processing and manufacturing, use reliable, cost performance advantages of higher.
In order to reach above-mentioned purpose, the technical scheme below the present invention has adopted:
A kind of curved boom; The straight-bar portion and the arcuate arm portions that comprise the one forging molding; Arcuate arm portions one end is connected with straight-bar portion; The arcuate arm portions other end is provided with the first boring end, and protrusion forms the second boring end in the middle of the arcuate arm portions, and the drilling axis of the said first boring end is parallel with the drilling axis of the second boring end.
As preferably, said arcuate arm portions is provided with sunk structure.
The present invention has been owing to adopted above technical scheme, have rational in infrastructure, make things convenient for processing and manufacturing, use reliable, cost performance advantages of higher.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Do a detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
Embodiment 1:
A kind of curved boom as shown in Figure 1; The straight-bar portion 1 and arcuate arm portions 2 that comprise the one forging molding; Arcuate arm portions 2 one ends are connected with straight-bar portion 1, and arcuate arm portions 2 other ends are provided with the first boring end 3, and protrusion forms the second boring end 4 in the middle of the arcuate arm portions 2; The drilling axis 31 of the said first boring end 3 is parallel with the drilling axis 41 of the second boring end 4,11 one-tenth angle a=10.9 ° of the drilling axis 31 of the said first boring end 3 and the axis of straight-bar portion 1.Two boring ends 3,4 are connected with another straight-arm parts through screw after boring.In the present embodiment, said arcuate arm portions 2 is provided with sunk structure 21, saving in material cost under the situation that guarantees bearing strength.
