Automotive U-bolt capable of directly reducing breakage

Abstract

The invention discloses an automotive U-bolt capable of directly reducing breakage. The automotive U-bolt comprises a main U-bolt body, wherein a bolt saddle part is arranged at the bottom of the main U-bolt body, a left bolt part is arranged on the left side of the main U-bolt body, a left screw thread part port is formed in the top of the left bolt part, a left screw thread part is arranged at the top of the left screw thread part port, a left bolt top is arranged at the top of the left screw thread part, and a left alloy nut is arranged on the side surface of the left screw thread part; a right bolt part is arranged on the right side of the main U-bolt body, and a right screw thread part port is formed in the top of the right bolt part; an austenite alloy layer is arranged in the main U-bolt body, and a nickel layer is arranged in a bamboo charcoal fiber layer. A casting technology adopting die-casting of various metal material layers is adopted, the bamboo charcoal fiber layer is attached to the bottom of the austenite alloy layer, the nickel layer is attached to the bottom of the bamboo charcoal fiber layer and is further tightly attached to a carbon steel outer core and a Q345 alloy steel inner core, and the material layers are attached and cast seamlessly.

Description

technical field [0001] The invention relates to the technical field of bolts, in particular to an automobile U-shaped bolt that directly reduces fracture. Background technique [0002] The so-called U-shaped bolts, of course, refer to the bolts used on trucks to stabilize the chassis and frame of the car. Their material properties should have high density, high bending strength, strong impact toughness, strong compressive strength, and elastic modulus. Large, high tensile strength and high temperature resistance. The shape is U-shaped, so it is also called U-bolt. There are threads at both ends that can be combined with nuts. It is mainly used for leaf springs of automobiles. Because the way it fixes objects is like a person riding It is the same on horses, so it is also called riding bolts. [0003] However, the functions of the existing U-shaped screws are limited, and because most of the U-shaped screws are cast with carbon steel, the existing U-shaped screws have low be...

AI Technical Summary

Problems solved by technology

[0003] However, the functions of the existing U-shaped screws are limited, and because most of the U-shaped screws are cast with carbon steel, the existing U-shaped screws have low bending strength, weak impact toughness, weak compressive strength, The shortcomings of small elastic modulus, low tensile strength and low temperature resistance are easy to cause fracture
