The invention discloses a diesel engine vibration isolation system used for isolating vibration of a diesel engine on a passenger car. The diesel engine vibration isolation system comprises a frame, a suspension subsystem and a secondary vibration isolation subsystem, wherein the frame comprises a left supporting rod, a right supporting rod and a front-end rod, and the suspension subsystem comprises a left connecting plate, a right connecting plate and a front-end plate; the secondary vibration isolation subsystem comprises a U-shaped skeleton, and a plurality of fixing plates are arranged at the two sides of left and right struts of the U-shaped skeleton; fixing holes are formed in the left and right supporting rods, and the U-shaped skeleton is fixedly connected with the frame through the fixing plates outside the U-shaped skeleton; the fixing plates inside the U-shaped skeleton are fixedly connected with the suspension subsystem, and one side, away from the U-shaped skeleton, of the left and right connecting plates is connected with a diesel engine; the two ends of the front-end rod are respectively connected with the upper ends of the left and right supporting rods, and one end of the front-end plate is connected with the middle of a suspension rod and the other end of the front-end plate is hinged to the engine. The diesel engine vibration isolation system provided by the invention has the advantages of simple structure and good vibration isolation effect.
Description
technical field [0001] The invention relates to the technical field of vibration isolation, in particular to a vibration isolation system for a diesel engine. Background technique [0002] Generally, gasoline engines have low vibration and high speed and are suitable for cars and light vehicles, while diesel engines have high power and good economy and are suitable for trucks. At present, four-cylinder gasoline engines are generally used as power plants in passenger cars. For the sake of power economy, it is hoped that two-cylinder diesel engines can be used instead of four-cylinder gasoline engines as power plants. However, the explosive pressure of the two-cylinder diesel engine will affect the comfort of the vehicle, and the existing suspension system cannot meet the vibration isolation requirements. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention proposes a diesel engine vibration isolatio...
