Description

Technical Field

[0001] The utility model belongs to the field of engine accessories, and in particular relates to an engine connecting rod assembly. Background Art

[0002] The automobile engine is a device that provides power for the car. It is the heart of the car and determines the car's power, economy, stability and environmental protection. According to the different power sources, automobile engines can be divided into diesel engines, gasoline engines, electric car motors and hybrid power. Common gasoline engines and diesel engines are both reciprocating piston internal combustion engines, which convert the chemical energy of the fuel into the mechanical energy of the piston movement and output power to the outside. Gasoline engines have high speed, small mass, low noise, easy starting and low manufacturing cost; diesel engines have a large compression ratio, high thermal efficiency, and better economic performance and emission performance than gasoline engines.

[0003] The internal structure of the engine is complex and has many parts. Some of these parts have special positional relationships. Ordinary connecting rods are straight rods and cannot connect the two, so special engine connecting rod assemblies are required. Utility Model Content

[0004] The utility model aims to provide an engine connecting rod assembly, wherein the connecting rod shaft and the supporting frame are arranged tiltedly, so as to facilitate the connection of parts with special positional relationships.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The engine connecting rod assembly comprises a support frame and a connecting rod shaft. The connecting rod shaft is tilted and fixed on the top of the support frame. An angle a is formed between the connecting rod shaft and the support frame in the vertical direction.

[0007] A certain angle a is set between the connecting rod shaft and the support frame to meet the connection requirements of two components in special positions.

[0008] Furthermore, support plates extending downward are provided on both sides of the support frame, and each support plate is provided with a mounting hole.

[0009] The mounting holes provided on the support plate are used to connect components so that they can be rotated or fixed in the support plate.

[0010] Furthermore, a reinforcement component is provided at the connection between the connecting rod shaft and the support frame.

[0011] Since the connecting rod shaft and the support frame are tilted, the force received at the connection between the two is uneven, which is prone to stress concentration and fatigue fracture. Strengthening components are used to protect the connection between the connecting rod shaft and the support frame.

[0012] Furthermore, the reinforcement assembly includes a reinforcement ring, which surrounds the connection between the connecting rod shaft and the support frame. A rubber ring is provided on the inner side of the reinforcement ring, and the rubber ring is against the connecting rod shaft.

[0013] The reinforcement assembly compresses the connection between the connecting rod shaft and the support frame through the rubber ring on the reinforcement ring, provides support for the connecting rod shaft, reduces possible vibration at the connection between the connecting rod shaft and the support frame, and reduces the occurrence of stress concentration and fatigue fracture.

[0014] Furthermore, the reinforcing assembly also includes a spring sheet and a fixing ring, two ends of the spring sheet are respectively fixed to the reinforcing ring and the fixing ring, and the fixing ring surrounds the connecting rod shaft.

[0015] The spring sheet and the fixing ring are used to fix the position of the reinforcing ring to prevent the reinforcing ring from being displaced due to the movement of the connecting rod and failing to protect the connection between the connecting rod shaft and the support frame.

[0016] Furthermore, the fixing ring is a clamp, and the clamp is tightly attached to the connecting rod shaft through a screw and a nut.

[0017] The clamp is used to fix the position of the entire reinforcement assembly to prevent it from moving up and down, and the size of the clamp is adjusted by a screw and a nut.

[0018] Furthermore, the fixing ring is parallel to the connecting rod axis in the horizontal direction, and the reinforcing ring is parallel to the top of the supporting frame.

[0019] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0020] A certain angle a is set between the connecting rod shaft and the support frame in the connecting rod assembly to meet the connection of two special position parts. The mounting holes provided on the support plate are used to connect the parts so that they can rotate or be fixed in the support plate.

[0021] Since the connecting rod shaft and the support frame are tilted, the force received at the connection between the two is uneven, which is prone to stress concentration and fatigue fracture. The reinforcement assembly protects the connection between the connecting rod shaft and the support frame. The reinforcement assembly presses the connection between the connecting rod shaft and the support frame through the rubber ring on the reinforcement ring, provides support for the connecting rod shaft, and reduces the possible shaking at the connection between the connecting rod shaft and the support frame, thereby reducing the occurrence of stress concentration and fatigue fracture. The spring sheet and the fixing ring are used to fix the position of the reinforcement ring to prevent the reinforcement ring from being displaced due to the movement of the connecting rod and failing to protect the connection between the connecting rod shaft and the support frame. The fixing ring is a clamp used to fix the position of the entire reinforcement assembly to prevent it from moving up and down. The size of the clamp is adjusted by the screw and nut.

[0028] like Figure 1 The engine connecting rod assembly shown includes a support frame 1 and a connecting rod shaft 2. The connecting rod shaft 2 is tilted and fixed on the top of the support frame 1. The connecting rod shaft 2 and the support frame 1 form an angle a in the vertical direction.

[0029] A certain angle a is set between the connecting rod shaft 2 and the support frame 1 to meet the connection of two special position parts. Support plates 3 extending downward are set on both sides of the support frame 1, and each support plate 3 is provided with a mounting hole 4. The mounting holes 4 provided on the support plate 3 are used to connect parts so that they can rotate or be fixed in the support plate 3.

[0033] Since the connecting rod shaft 2 and the support frame 1 are tilted, the force received at the connection between the two is uneven, which is prone to stress concentration and fatigue fracture. A strengthening component is used to protect the connection between the connecting rod shaft 2 and the support frame 1.

[0034] The reinforcement assembly includes a reinforcement ring 5, which surrounds the connection between the connecting rod shaft 2 and the support frame 1. A rubber ring 6 is provided inside the reinforcement ring 5, and the rubber ring 6 abuts against the connecting rod shaft 2. The reinforcement assembly also includes a spring sheet 7 and a fixing ring 8, and the two ends of the spring sheet 7 are respectively fixed to the reinforcement ring 5 and the fixing ring 8, and the fixing ring 8 surrounds the connecting rod shaft 2.

[0035] The reinforcing assembly compresses the connection between the connecting rod shaft 2 and the support frame 1 through the rubber ring 6 on the reinforcing ring 5, provides support for the connecting rod shaft 2, reduces the possible shaking of the connection between the connecting rod shaft 2 and the support frame 1, and reduces the occurrence of stress concentration and fatigue fracture.

[0036] The spring sheet 7 and the fixing ring 8 are used to fix the position of the reinforcement ring 5 to prevent the reinforcement ring 5 from being displaced due to the movement of the connecting rod and failing to protect the connection between the connecting rod shaft 2 and the support frame 1. The fixing ring 8 is a clamp, which is tightly attached to the connecting rod shaft 2 through a screw 9 and a nut 10. The clamp is used to fix the position of the entire reinforcement assembly to prevent it from moving up and down, and the size of the clamp is adjusted by the screw 9 and the nut 10.

[0037] like Figure 3 and Figure 4 As shown, the fixing ring 8 is parallel to the connecting rod shaft 2 in the horizontal direction, and the reinforcing ring 5 is parallel to the top of the supporting frame 1.
