Embodiment Construction

[0011] like figure 1 and figure 2 As shown, a secondary foam steering wheel for yachts and motor vehicles is composed of a foam wheel rim 1 and a frame 6 connected to it. The foamed rim 1 is composed of a primary foam 3 and a secondary foam 5 .

[0012] like figure 1 and figure 2 As shown, the positions of the primary foam 3 and the secondary foam 5 and the proportions of the primary foam 3 and the secondary foam 5 are determined as needed. in the attached figure 1 In the first embodiment shown, the primary foam body 3 is located in the corresponding part of the stainless steel cylindrical bar 7, and there are three sections in total. The rest are secondary foam 5, which also has 3 stages. The ratio of the primary foam 3 to the secondary foam 5 is approximately 1:3. in the attached figure 2 In the second embodiment shown, the primary foam body 3 is located on the upper and lower parts of the steering wheel, and there are two sections in total. The rest are secondar...

Abstract

A secondly foamed steering wheel for yacht or motor-driven vehicle is composed of the foamed wheel rim consisting of the primarily foamed body and the secondly foamed body, and the skeleton connected with said wheel rim.

Description

Technical field [0001] The invention relates to components of steering systems of vehicles and ships, in particular to the foamed rim steering wheels of yachts and motor vehicles. Background technique [0002] The structure of the steering wheel has a steel skeleton inside and a whole skin of PU semi-rigid foam on the outside. It is made by reaction injection (RIM) at one time with both a tough and dense outer skin and a honeycomb inner core. The thickness of the formed skin is from several tenths. mm to 5 mm. Skin density 1000~1200kg / m 3 , while the inner core density is several hundred kg / m 3 . The skin layer and core layer of the product are connected together as a whole, and the continuous, smooth and soft skin layer can protect the core layer from mechanical damage. Whole skin PU semi-rigid foam can be obtained in various densities and hardnesses according to different formulations. [0003] In the existing foamed rim steering wheels for yachts and motor vehicles, ...
