Novel engine suspension

Abstract

The invention discloses a novel engine suspension. The novel engine suspension comprises a shell, an upper end cover detachably connected with the shell, a hydraulic device and a middle channel formedin the inner wall of the shell, the outer edge of the middle channel abuts against the inner wall of the shell in the peripheral direction, a center hole runs through the center part of the middle channel, and the lower end of the shell is connected with a supporting frame at the bottom through a rubber element. The suspension structure is arranged, the middle channel and a hydraulic piston are arranged inside the suspension shell, vibration of an engine under different vibration magnitudes and vibration frequencies can be effectively attenuated, the vibration, transmitted to a frame, of theengine is lowered to the maximum degree, the suspension integrates air damping vibration reduction, sieve vibration reduction, oil gas diaphragm vibration reduction, rubber vibration reduction and torsion rod vibration reduction, through a sieve, small-magnitude vibration can be attenuated, and through a rubber oil gas diaphragm and a torsion rod spring, large-magnitude vibration can be attenuated.

Description

technical field [0001] The invention belongs to the technical field of engine mounts, in particular to a novel engine mount. Background technique [0002] The car is a multi-mass system composed of multiple mass bodies, elastic bodies and dampers. The engine is a main vibration source on the car, and its vibration is transmitted from the powertrain to the frame or body through the suspension system. The engine mount is installed between the engine and the chassis of the car to support the powertrain and isolate the transmission of engine vibration energy to the chassis and body. A good engine mount can effectively reduce the vibration and noise level of the vehicle and effectively improve the ride quality of the car. Comfort, and can prolong the service life of the engine and other components. [0003] The existing engine mounts generally have a good effect of isolating vibrations. However, the mounts have low stiffness and insufficient limit capability. When the car is bum...

Problems solved by technology

[0003] Existing engine mounts generally have a good effect of isolating vibrations. However, the mounts have low stiffness and insufficient limit capability. When the car is bumped significantly, the engine mounts cannot effectively reduce the large displacement of the engine due to inertia. In the end, the powertrain itself will collide with the surrounding parts and be damaged. At the same time, the suspension device is also easily damaged, reducing the impact of the vibration of the engine suspension on the vehicle, limiting the amount of vibration, and affecting the NVH performance (noise, noise, etc.) of the vehicle. vibration and harshness) play a very large role
