Problems solved by technology

[0002] Most of the existing steering wheel skeletons are made of metal materials, consisting of a ring-shaped coil, a steering hub inserted into the steering shaft, and spokes connected to the coil, which are formed by welding or casting processes. The disadvantage is that the overall quality is relatively heavy , large rebound force when impacted, strong temperature sensitivity, poor hand feeling and low recovery rate

Abstract

The present invention provides one kind of nylon composition for skeleton of automobile steering wheel and its production process. The nylon composition is prepared through mixing nylon-6 slice, inorganic mineral, solvent, antioxidant and coupling agent in a high speed mixer; mixing with glass fiber and pelletizing in a screw extruder; cooling and stoving. The nylon composition is made into skeleton of automobile steering wheel through injection molding and foaming. The steering wheel skeleton of the nylon composition has high stability, high strength, low bounce, light weight and other advantages.

Description

technical field [0001] The invention discloses a nylon composition and a manufacturing method for automobile steering wheel skeletons, and relates to the technical field of automobile parts manufacturing. Background technique [0002] Most of the existing steering wheel skeletons are made of metal materials, consisting of a ring-shaped coil, a steering hub inserted into the steering shaft, and spokes connected to the coil, which are formed by welding or casting processes. The disadvantage is that the overall quality is relatively heavy , The rebound force generated during impact is large, the temperature sensitivity is strong, the hand feeling is poor, and the recovery rate is small. Contents of the invention [0003] The invention provides a nylon composition used for the frame of the steering wheel of an automobile, which can replace the metal material to manufacture the frame of the steering wheel. [0004] The invention also provides a steering wheel made of the above...
