[0020] The present utility model provides a wear-resistant connecting rod for an automobile, which includes a connecting rod body 101, a connecting rod big end 102, a connecting rod small end 103, a rotating unit, a big end bearing shell 104, a plurality of spherical balls 105, a plurality of connecting rod bolts 106 and a plurality of reinforcing rods 107. The rotating unit includes a small end bushing 108, a plurality of rotating balls 109 and a clamping groove ring 110. The inner wall of the small end bushing 108 has a plurality of circular grooves 111, and the inner wall of the connecting rod big end 102 has a groove 112.

[0021] For this specific embodiment, when the connecting rod small end 103 is connected to the piston pin, it is fixedly connected to the piston pin through the clamping groove ring 110. When the clamping groove ring 110 is driven by the piston pin to rotate, with the cooperation of the plurality of rotating balls 109, the rotation of the clamping groove ring 110 is smoother, reducing the friction force, thereby reducing the wear damage suffered by the device during use. Connect the big end bearing shell 104 to the crankshaft. When the crankshaft drives the big end bearing shell 104 to rotate, with the cooperation of the plurality of spherical balls 105, the friction force during the rotation of the big end bearing shell 104 is reduced, thereby avoiding the situation where the big end bearing shell 104 is worn out, improving the durability of the device. The connecting rod big end 102 and the connecting rod body 101 are connected and fixed through the plurality of connecting rod bolts 106, thereby improving the stability effect of the connecting rod big end 102. Through the arrangement of the plurality of reinforcing rods 107, the firmness and stability effect of the connecting rod body 101 are improved. Before the device operates, lubricating oil is sprayed at the joints with the piston pin and the crankshaft, thereby reducing the friction force and reducing the wear damage suffered by the device. When the engine is working, the piston makes a reciprocating linear motion in the cylinder. When the piston moves downward, the device pushes the crankshaft to rotate; when the piston moves upward, the device is pulled back by the pulling force of the crankshaft; in this way, the reciprocating linear motion of the piston is converted into the rotational motion of the crankshaft, thereby driving the engine to output power.

[0022] Among them, the small end 103 of the connecting rod is fixedly connected to the connecting rod body 101 and is located at the upper end of the connecting rod body 101. The big end 102 of the connecting rod is fixedly connected to the connecting rod body 101 and is located at the lower end of the connecting rod body 101. The inner wall of the small end bushing 108 has a plurality of circular grooves 111. The small end bushing 108 is arranged inside the small end 103 of the connecting rod. A plurality of the rotating balls 109 are respectively rotationally adapted to the corresponding circular grooves 111. The clamping groove ring 110 is located inside the small end bushing 108, and the clamping groove ring 110 is adapted to a plurality of the rotating balls 109. When the small end 103 of the connecting rod is connected to the piston pin, it is fixedly connected to the piston pin through the clamping groove ring 110. When the clamping groove ring 110 is driven by the piston pin to rotate, with the cooperation of a plurality of the rotating balls 109, the rotation of the clamping groove ring 110 is smoother, reducing the friction force, thereby reducing the wear damage suffered by the device during use. Before the device operates, lubricating oil is sprayed at the joints with the piston pin and the crankshaft, thereby reducing the friction force and reducing the wear damage suffered by the device. When the engine works, the piston makes a reciprocating linear motion in the cylinder. When the piston moves downward, the device pushes the crankshaft to rotate; when the piston moves upward, the device is pulled back by the pulling force of the crankshaft; in this way, the reciprocating linear motion of the piston is converted into the rotational motion of the crankshaft, thereby driving the engine to output power.

[0023] Secondly, the inner wall of the big end 102 of the connecting rod has a groove 112, and the big end bearing shell 104 is rotationally adapted to the groove 112. A plurality of the spherical balls 105 are respectively arranged between the groove 112 and the big end bearing shell 104. When the big end bearing shell 104 is connected to the crankshaft and the crankshaft drives the big end bearing shell 104 to rotate, with the cooperation of a plurality of the spherical balls 105, the friction force when the big end bearing shell 104 rotates is reduced, thereby avoiding the situation that the big end bearing shell 104 is worn out and damaged, and improving the durability of the device.

[0024] At the same time, a plurality of the connecting rod bolts 106 respectively penetrate through the big end 102 of the connecting rod and are respectively located inside the connecting rod body 101. The big end 102 of the connecting rod and the connecting rod body 101 are connected and fixed through a plurality of the connecting rod bolts 106, thereby improving the stability effect of the big end 102 of the connecting rod.

[0025] In addition, a plurality of the reinforcing rods 107 are respectively arranged inside the connecting rod body 101. Through the arrangement of a plurality of the reinforcing rods 107, the firmness and stability effect of the connecting rod body 101 are improved.

[0026] When using the wear-resistant connecting rod for automobiles of the present utility model, when the small end 103 of the connecting rod is connected to the piston pin, it is fixedly connected to the piston pin through the clamping groove ring 110. When the clamping groove ring 110 is driven to rotate by the piston pin, with the cooperation of a plurality of rotating balls 109, the rotation of the clamping groove ring 110 is smoother, reducing the friction force, thereby reducing the wear damage suffered by the device during use. Connect the big end bearing shell 104 to the crankshaft. When the crankshaft drives the big end bearing shell 104 to rotate, with the cooperation of a plurality of spherical balls 105, the friction force during the rotation of the big end bearing shell 104 is reduced, thereby avoiding the situation that the big end bearing shell 104 is worn out and damaged, and improving the durability of the device. Connect and fix the big end 102 of the connecting rod and the connecting rod body 101 through a plurality of connecting rod bolts 106, thereby improving the stability effect of the big end 102 of the connecting rod. Through the arrangement of a plurality of reinforcing rods 107, the firmness and stability effect of the connecting rod body 101 are improved. Before the device operates, lubricating oil is sprayed at the joints with the piston pin and the crankshaft, thereby reducing the friction force and reducing the wear damage suffered by the device. When the engine works, the piston makes a reciprocating linear motion in the cylinder. When the piston moves downward, the device drives the crankshaft to rotate; when the piston moves upward, the device is pulled back by the pulling force of the crankshaft; in this way, the reciprocating linear motion of the piston is converted into the rotational motion of the crankshaft, thereby driving the engine to output power.
