The utility model discloses the surface between bulb position on the control arm body and the muscle is raised for the control arm obtains the promotion that is showing at the ascending rigidity of X side, and rigidity has reached 2.33KN/mm, has satisfied the rigidity target value of requirement, and has made weight reduce 0.145kg, has realized the lightweight.
Description
Technical Field
The utility model relates to an automobile parts's field, concretely relates to lightweight, high rigidity control arm.
Background
When the automobile is subjected to impact load in the driving process, the control arm serving as a connecting piece for connecting the auxiliary frame and the steering knuckle also bears huge impact load, and the control arm needs to have enough rigidity to resist the impact load. The main sleeve 1 and the body 2 of the control arm of the prior art scheme are composed, and the body 2 and the sleeve 1 of the control arm are welded along a contacted side line according to the initial position and the length of a welding seam 3, so that a control arm welding assembly is formed. As shown in fig. 4, the weak point 4 is smoothly connected, so that the rigidity of the structure in the X direction is weak. Through finite element simulation check, the X-direction rigidity at the position is 1.65KN/mm, and the performance requirement with the target value of 2KN/mm cannot be met.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a lightweight, high rigidity control arm.
The purpose of the utility model is accomplished through following technical scheme: a light and high-rigidity control arm mainly comprises a sleeve, a body, a ball head, grooves, protrusions and through holes, wherein one side of the body is connected with the sleeve, one end of the body is the ball head, the grooves are formed in the surface of the body, ribs are formed on two sides of the body, and the ribs are smoothly connected with the ball head; a bulge is arranged between the ball head and the groove and is 20-50mm close to the center of the ball head, the bulge is of a structure with a high middle part and two low sides, the bulge is smoothly connected with the groove, the highest part of the bulge is 5-10mm higher than the upper surface of the body, and a through hole is arranged at the groove at the center of the body.
The elevation connection increases the thickness of the material at the joint, and the body and the sleeve are welded.
The utility model has the advantages that: the utility model discloses the surface between bulb position on the control arm body and the muscle is raised for the control arm obtains the promotion that is showing at the ascending rigidity of X side, and rigidity has reached 2.33KN/mm, has satisfied the rigidity target value of requirement, and has made weight reduce 0.145kg, has realized the lightweight.

Description of reference numerals: the sleeve comprises a sleeve 1, a body 2, a welding seam 3, a weak part 4, a ball head 5, a groove 6, a protrusion 7, a through hole 8 and a rib 9.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawings, the light-weight high-rigidity control arm mainly comprises a sleeve 1, a body 2, a ball 5, a groove 6, a protrusion 7 and a through hole 8, wherein one side of the body 2 is connected with the sleeve 1, one end of the body 2 is provided with the ball 5, the surface of the body 2 is provided with the groove 6, ribs 9 are formed on two sides of the body 2, and the ribs 9 are smoothly connected with the ball 5; a bulge 7 is arranged between the ball head 5 and the groove 6 and is 20-50mm close to the center of the ball head 5, the bulge 7 is of a structure with a high middle and two low sides, the bulge 7 is smoothly connected with the groove 6, the bulge 7 is connected with the ball head 5, the highest position of the bulge 7 is 5-10mm higher than the upper surface of the body 2, and a through hole 8 is arranged at the groove 6 at the center of the body 2 to reduce the weight.
According to the invention, through improving the structure of the control arm and CAE simulation verification, after the control arm applies 1000N load in the X direction, the displacement value of the position of the ball head 5 is reduced from 0.606mm to 0.43mm, as shown in the attached drawings 6 and 7, the rigidity is improved from 1.65KN/mm to 2.33KN/mm, and is improved by 41.2%; the weight is reduced from 2.69kg to 2.54kg by 5.6 percent, thereby not only meeting the performance requirement, but also realizing the light weight.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
