Fiber pultrusion reinforced plastic automobile saddle hinge pin

Abstract

The invention discloses a fiber pultrusion reinforced plastic automobile saddle hinge pin which comprises a plastic jacket and a central spindle. The plastic jacket is assembled on the central spindleby means of fiber reinforced plastic pultrusion or winding molding, a guide metal sleeve selectively wraps a core of the plastic jacket, and a fixing component is arranged at an end of the central spindle. The fiber pultrusion reinforced plastic automobile saddle hinge pin has the advantages that the weight of the fiber pultrusion reinforced plastic automobile saddle hinge pin can be reduced by 1kg, in other word, approximately 50%-60%, as compared with the original all-metal component, an automobile can be provided with two fiber pultrusion reinforced plastic automobile saddle hinge pins, accordingly, fiber pultrusion reinforced plastic automobile saddle hinge pin is favorable for reducing the weight of the integral automobile, and fuel can be saved; the fiber pultrusion reinforced plastic automobile saddle hinge pin is applicable to cylindrical support components for supporting saddles on automobiles and trailers.

Description

technical field [0001] The invention relates to a fiber pultrusion reinforced plastic automobile saddle pin. Background technique [0002] Existing automobile saddle pins are metal (steel) machine-welded and formed, with high quality, weak welding, weak welding, missing welding, and welding stress, and iron materials will rust when exposed to the outside of the vehicle; metal parts need to be painted Install anti-corrosion, it will rust after the coating falls off, and it is not easy to disassemble and replace; the material utilization rate of machining process is low, there are many processing procedures, and the cost is high. Therefore, in view of this situation, it is urgent to develop a fiber pultrusion reinforced plastic automobile saddle pin to overcome the shortcomings in current practical applications. Contents of the invention [0003] The purpose of the present invention is to provide a fiber pultrusion reinforced plastic automobile saddle pin to solve the probl...
