The engine mount is the bridge connecting the engine and the frame. Existing engine mounts, including bows, cantilevers and bases, are heavy in weight and do not serve the existing lightweighting purpose. At the same time, the engine, the engine bracket and the frame are rigidly connected, and the bumps generated during the driving of the car are easily transmitted to the engine, and the noise is large. Due to the large vibration of the engine during operation, the frame and the frame are periodically impacted, resulting in deformation of the frame and the frame. In order to eliminate these adverse consequences, the engine bracket generally adopts elastic support. There are longitudinal tie rods on the engine bracket, which are used to prevent the longitudinal displacement of the engine due to the deformation of the elastic element when the car is braking or accelerating. They are attached to the frame rails and engine via rubber washers.
