Car engine inner support

Abstract

The invention discloses a car engine inner support in the technical field of car engine accessories. The car engine inner support comprises a main connecting plate, screws, square frames and the like.The car engine inner support has the advantages the main connecting plate can be connected with a car body beam only by rotating the square frames to rotate the screws without other tools, and mounting convenience is achieved; each square frame can be rotated by the hand by a transverse rods and an X-shaped rod in the square frame, and the mounting convenience of the car engine inner support is further increased; vibration generation by an engine is transmitted to a damping cylinder through a mounting panel, the damping cylinder can consume part of vibration force through curved-surface vibration, the rest of vibration force is transmitted to a main damping pad through the lower end of the damping cylinder, the main damping pad consumes the vibration force through vibration again, the residual vibration force can be effectively transmitted to an arc-shaped damping pad due to the fact that the contact area between the arc-shaped damping pad and the main damping pad is large, the vibration force is consumed again through the vibration of the arc-shaped damping pad, and the quietness degree in a cab is increased effectively.

Description

technical field [0001] The invention relates to the technical field of automobile engine accessories, in particular to an automobile engine inner bracket. Background technique [0002] The biggest source of automobile vibration is the engine and tires. As the main power source of the automobile, the engine has achieved an irreplaceable position in vehicle engineering. However, due to its special structure and working method, the engine has also become a main vibration source of the automobile. , the strong vibration generated by the engine not only vibrates the body itself, but also excites the components and various accessories in the body to cause impact vibration, which reduces the comfort of the driver and passengers, and affects the safety and ride comfort of the vehicle. With the development of society, the comfort of car driving has gradually become a concern of people, which makes engine vibration reduction increasingly the focus of research.

[0002] The biggest source of automobile vibration is the engine and tires. As the main power source of the automobile, the engine has achieved an irreplaceable position in vehicle engineering. However, due to its special structure and working method, the engine has also become a main vibration source of the automobile. , the strong vibration generated by the engine not only vibrates the body itself, but also excites the components and various accessories in the body to cause impact vibration, which reduces the comfort of the driver and passengers, and affects the safety and ride comfort of the vehicle. With the development of society, the comfort of car driving has gradually become a concern of people, which makes engine vibration reduction increasingly the focus of research. The engine inner bracket mainly plays a role in fixing and damping the car engine, and can be placed between the engine and the body beam. It forms a soft connection, buffers the vibration of the engine when it is working, and also plays a role in connecting and fixing the engine. If there is a problem with the inner bracket of the engine, there will be vibration of the vehicle body and increased noise in the cab. In severe cases, the engine will fall off directly, so Bracket is one of the essential parts of the engine and plays an important role. The structure of the existing internal bracket of the engine is relatively simple, and rubber pads are generally used to achieve the purpose of vibration reduction. Due to the simple structure, the vibration reduction effect is general, and the rubber pads are aging. The problem of fast speed leads to a high frequency of replacement of the engine inner bracket, and there is a problem of poor convenience for the installation of the engine inner bracket during replacement. Therefore, an automobile engine inner bracket is proposed
