Bionic lightweighting steering system

Abstract

The invention discloses a bionic lightweighting steering system including a knuckle; the upper part of the knuckle is hinged with an upper cross arm through a ball pin; the upper cross arm is in a fish head shape; a plurality of circular holes are formed in the upper and lower end surfaces of the upper cross arm; a pin rod of the ball pin is fixedly connected with the knuckle; a ball head of the ball pin is hinged to the upper cross arm; a supporting arm is fixed at the lower part of the knuckle; the supporting arm is hinged to a lower cross arm, and a plurality of round holes are further formed in the lower cross arm; a plurality of sets of symmetrical through hole structures are distributed on the side end face of the upper cross arm, the upper end face and the lower end face of the lower cross arm, an upper end bent arm side end face of the knuckle and a lower end right-angle arm end face of the knuckle, and a better lightweighting effect is achieved on the premise that a structuralperformance is met.

Description

technical field [0001] The invention relates to the technical field of automobile steering systems, in particular to a bionic lightweight steering system. Background technique [0002] The steering system of an automobile is the mechanism that ensures the steering of the automobile, so its structural performance is particularly important. The mainstream trend of modern automobile design is to reduce the mass of parts as much as possible to reduce energy consumption under the premise of ensuring the performance of parts. However, the components of traditional steering systems are mainly forged steel or casting, and the products produced are of high quality and simple in structure, and most of them are solid structures. At present, the design and optimization of the steering system topology mainly adopts the method of combining engineering experience and finite element analysis. The strength and stiffness are checked by setting a high safety factor, and repeated many times to...

However, the components of the traditional steering system are mainly forged steel or casting, and the products produced are of high quality and simple structure, and most of them are solid structures

At present, the design and optimization of the steering system topology mainly adopts the method of combining engineering experience and finite element analysis. The strength and stiffness are checked by setting a high safety factor, and repeated many times to meet the design requirements. This method works Large and cumbersome, it is difficult to give full play to the load-bearing performance of the body

The topology optimization method has been widely concerned by various automobile companies because it can provide lightweight and efficient structural forms and solutions in the conceptual design stage. However, the structure of the steering system is complex. If topology optimization is directly performed on it, there is a problem that the topology results are difficult to identify

Therefore, even with an optimized design of the steering system, its lightweight effect is still unsatisfactory
