As mentioned in the background art, the engine mounting system in the related art has the problem of poor durability of the rubber bearing. The inventor found through research that the reason for this problem is that when the engine torque increases, the power assembly and the engine The displacement will increase. Due to the lack of a limiting structure between the engine mount and the rubber support in the relevant engine mounting system, when the displacement of the powertrain and engine increases, the rubber in the rubber support and the engine mount will shake as a whole. The greater the amplitude, the greater the shaking amplitude of the rubber will lead to a deterioration in the durability of the rubber, which will in turn lead to a deterioration in the durability of the rubber support.

In view of the above technical problems, embodiments of the present application provide an engine mounting system and a vehicle. A first limiting member is provided on the vibration isolation assembly, and a second limiting member is provided on the engine bracket. The second limiting member is connected to the third limiting member. A limiter is facing and arranged at intervals. When the engine bracket, the first mounting plate and the elastic member are as a whole rocking relative to the second mounting plate along the inclination direction of the second mounting plate, the second limiter and the first The limiting parts are in contact to reduce the shaking amplitude of the engine bracket, the first mounting plate and the elastic component relative to the second mounting plate, thereby improving the durability of the elastic component and the vibration isolation assembly.

The principles and features of the embodiments of the present application are described below with reference to the accompanying drawings. The examples cited are only used to explain the embodiments of the present application and are not used to limit the scope of the embodiments of the present application.

Referring to Figure 1, this embodiment provides an engine mounting system, which includes an engine bracket 10, a vibration isolation assembly 20 and a lower crossbeam assembly 30. The engine bracket 10, the vibration isolation assembly 20 and the lower crossbeam assembly 30 are connected in sequence. The engine bracket 10 is For connecting with the engine, the lower cross member assembly 30 is used to connect with the vehicle frame 50. The vibration isolation assembly 20 is connected between the engine bracket 10 and the lower cross member assembly 30 to block the vibration transmission between the engine bracket 10 and the lower cross member assembly 30. This prevents mutual transmission of vibration between the engine and the vehicle frame 50 .

Referring to Figures 2 and 3, the vibration isolation assembly 20 includes an elastic member 210, a first mounting plate 220, a second mounting plate 230 and a first limiting member.

An embodiment of the present application also provides a vehicle, including an engine, a frame 50 and the engine mounting system in the previous embodiment. The engine mounting system is installed between the engine and the frame 50 to block the gap between the engine and the frame 50 Vibrations are transmitted to each other. The specific structure, working principle and function of the engine mounting system have been described in detail in the previous embodiments and will not be described again here.

The vehicle in this embodiment includes an engine and an engine mounting system. The engine mounting system includes a vibration isolation assembly 20 and an engine bracket 10. A first limiter is provided on the vibration isolation assembly 20, and a third stopper is provided on the engine bracket 10. Two limiting members, the second limiting member is opposite to the first limiting member and is arranged at intervals. The engine bracket 10, the first mounting plate 220 and the elastic member 210 are formed as a whole relative to the second mounting plate 230 along the second When the mounting plate 230 shakes in the tilt direction, the second limiting member contacts the first limiting member to reduce the relative position of the engine bracket 10 , the first mounting plate 220 and the elastic member 210 relative to the second mounting plate 230 . The shaking amplitude is thereby improved, thereby improving the durability of the elastic member 210 and the vibration isolation assembly 20 .

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: The technical solutions described in the foregoing embodiments can still be modified, or some or all of the technical features can be equivalently replaced; and these modifications or substitutions do not deviate from the essence of the corresponding technical solutions from the technical solutions of the embodiments of the present application. scope.
