Problems solved by technology

In the above-mentioned technical solution, the welding process and positioning of the steering wheel metal body are very demanding, and it is very easy to form welding slag or welding deformation in the steel pipe, and even lead to scrapping; in addition, some manufacturers also use the mahogany production process, but after the overall foaming , can not do ABS injection molding, only the foam body of the mahogany part is cut and decorated with mahogany, but the overall effect is destroyed, and the thickness of the outer ring of the disc is uneven

Embodiment 1

[0025] combine figure 1 , 2, 4, 5, the steering wheel includes a magnesium alloy skeleton body 10 that includes an annular upper rim 11, a lower base 12, and several auxiliary ribs 13 that are die-cast into an integral structure, such as Figure 4 , 5 As shown, the magnesium alloy is used to make the skeleton, which has light weight, high specific strength and specific stiffness, and has electromagnetic and vibration absorption properties. It also has good high and low temperature performance, and small deformation is conducive to dimensional stability and good mold release performance. The small half upper disc edge 11 on the disc body 10 is injection molded with an ABS coating 20, such as Figure 6 , 7 , the ABS cladding layer 20 is provided with a transfer layer 30 of mahogany texture, such as Figure 9 , 11 , the structure not only has good appearance and aesthetic effect, but also has good wear resistance and strength. The rest of the upper disc rim 11 is provided wi...

Embodiment 2

[0030] Such as image 3 As shown, the processing method of the steering wheel in the present invention simply includes die-casting, ABS injection molding, foaming, transfer printing, leather wrapping and assembly process, and the steps are described in detail below:

[0031] Such as Figure 4 , 5 As shown, a die-casting method is used to form a magnesium alloy skeleton disk body 10 with an integral structure including an annular upper flange 11, a lower base 12, and several auxiliary ribs 12 arranged therebetween. The magnesium alloy skeleton disk body 10 in the present invention According to the specific requirements of customers, the specific structure of the lower base 12 and several auxiliary ribs 12 arranged therebetween can be provided to meet the requirements of installing or optional air bag assembly 60 and horn assembly 70, as well as the cooperation with the specific structure of power-assisted steering. The magnesium alloy frame body is molded at one time by cold ...

Abstract

The present invention discloses a steering wheel for automobile and its production method. Said steering wheel includes a magnesium alloy skeleton wheel body containing ring upper portion wheel rim, lower portion base seat and several auxiliary ribs between them which are die-cast into one integrated structure, the upper portion wheel rim of small half-portion of said wheel body is covered with ABS covering layer, its exterior is covered with transferred layer with peach wood grain, and other portion of the described upper portion wheel rim is equipped with foamed layer, and the exterior of said foamed layer is covered with leather layer. Said invented product quality is reliable, and its appearance and hand feel can be obviously improved.

Description

technical field [0001] The invention relates to a steering assembly of an automobile. Background technique [0002] In order to meet the good maneuverability of driving cars, merchants and designers continue to improve the design of the steering wheel, and today the airbag is set on the steering wheel, and the structure and performance of the steering wheel have undergone tremendous changes and improvements. A steering wheel assembly generally includes a metal skeleton on the inside and a cladding on the outside of the skeleton. The internal metal skeleton of the steering wheel in domestic and foreign products is usually composed of several parts fixedly connected, and then the above metal skeleton is integrally molded in a plastic body, such as the name "integrated steering wheel and airbag storage assembly" (ZL97117601.9) and "Automotive Steering Wheel Integrated with Airbag Restraint System" (Application No. 95115094.4). , these spoke bars are integrally molded into a p...
