正如背景技术所述,相关技术中的发动机悬置系统存在橡胶支承的耐久性差的问题,经发明人研究发现,出现这种问题的原因在于,发动机在扭矩增大时,动力总成和发动机的位移会增大,由于相关发动机悬置系统中发动机支架和橡胶支承之间缺乏限位结构,导致在动力总成和发动机的位移增大时,橡胶支承中的橡胶和发动机支架构成的整体的晃动幅度增大,橡胶的晃动幅度增大会导致橡胶的耐久性变差,进而导致橡胶支承的耐久性变差。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.

针对上述技术问题,本申请实施例提供一种发动机悬置系统及车辆,通过在隔振组件上设置第一限位件,在发动机支架上设置第二限位件,第二限位件与第一限位件正对且间隔设置,在发动机支架、第一安装板和弹性件所构成的整体相对于第二安装板沿第二安装板的倾斜方向晃动时,第二限位件与第一限位件抵接,以减小发动机支架、第一安装板和弹性件所构成的整体相对于第二安装板的晃动幅度,从而提高了弹性件和隔振组件的耐久性。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.

以下结合附图对本申请实施例的原理和特征进行描述,所举实例只用于解释本申请实施例,并非用于限定本申请实施例的范围。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.

参考图1,本实施例提供一种发动机悬置系统,包括发动机支架10、隔振组件20和下横梁组件30,发动机支架10、隔振组件20和下横梁组件30依次连接,发动机支架10用于与发动机连接,下横梁组件30用于与车架50连接,隔振组件20连接于发动机支架10和下横梁组件30之间,以阻隔发动机支架10和下横梁组件30之间的振动传递,进而避免发动机和车架50之间相互传导振动。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 .

参考图2和图3,隔振组件20包括弹性件210、第一安装板220、第二安装板230和第一限位件,第一安装板220与第二安装板230平行且间隔设置,第二安装板230相对于水平面倾斜设置,弹性件210可以为橡胶件、硅胶件等,弹性件210设置于第一安装板220和第二安装板230之间,弹性件210的底面与第二安装板230贴合,顶面与第一安装板220贴合。第一限位件设置于第二安装板230的沿倾斜方向的一端,且第一限位件朝向第一安装板220延伸。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. The first mounting plate 220 and the second mounting plate 230 are arranged parallel and spaced apart. The second mounting plate 230 is tilted relative to the horizontal plane. The elastic member 210 can be a rubber member, a silicone member, etc. The elastic member 210 is disposed between the first mounting plate 220 and the second mounting plate 230 . The bottom surface of the elastic member 210 is in contact with the second mounting plate 230 . The mounting plate 230 is bonded, and the top surface is bonded to the first mounting plate 220 . The first limiting member is provided at one end of the second mounting plate 230 along the tilt direction, and the first limiting member extends toward the first mounting plate 220 .

参考图3和图4,发动机支架10包括悬置支承安装板110和第二限位件,悬置支承安装板110与第一安装板220贴合,第二限位件设置于悬置支承安装板110的沿第二安装板230的倾斜方向的一端,且第二限位件朝向第二安装板230延伸,第二限位件与第一限位件正对且间隔设置。Referring to Figures 3 and 4, the engine bracket 10 includes a suspension support installation plate 110 and a second limiter.

One end of the plate 110 is along the inclination direction of the second mounting plate 230, and the second limiting member extends toward the second mounting plate 230. The second limiting member is directly opposite to and spaced apart from the first limiting member.

在发动机支架10与发动机连接,且发动机工作时,发动机的振动会通过发动机支架10、第一安装板220传递到弹性件210,使得弹性件210的顶部相对于第二安装板230沿第二安装板230的倾斜方向往复摆动,而弹性件210的底部不随着发动机的振动而摆动,从而避免发动机的振动传递到下横梁组件30。When the engine bracket 10 is connected to the engine and the engine is running, the vibration of the engine will be transmitted to the elastic member 210 through the engine bracket 10 and the first mounting plate 220, so that the top of the elastic member 210 is along the second mounting direction relative to the second mounting plate 230. The inclined direction of the plate 230 swings back and forth, but the bottom of the elastic member 210 does not swing with the vibration of the engine, thereby preventing the vibration of the engine from being transmitted to the lower cross member assembly 30 .

第二限位件与第一限位件正对且间隔设置,在发动机输出的扭矩较大时,发动机支架10、第一安装板220和弹性件210所构成的整体相对于第二安装板230沿第二安装板230的倾斜方向晃动,且第二限位件与第一限位件抵接,以减小弹性件210相对于第二安装板230沿第二安装板230的倾斜方向的晃动幅度,从而提高了弹性件210和隔振组件20的耐久性。The second limiting member is directly opposite to the first limiting member and is arranged at intervals. When the torque output by the engine is relatively large, the whole body composed of the engine bracket 10, the first mounting plate 220 and the elastic member 210 is relative to the second mounting plate 230. The elastic member 210 rocks along the tilt direction of the second mounting plate 230 , and the second limiting member contacts the first limiting member to reduce the rocking of the elastic member 210 relative to the second mounting plate 230 along the tilting direction of the second mounting plate 230 . amplitude, thereby improving the durability of the elastic member 210 and the vibration isolation assembly 20 .

参考图1和图3,在一些实施例中,第一限位件可以设置于第二安装板230的沿第二安装板230的倾斜方向的顶端,第二限位件可以设置于悬置支承安装板110的沿平行于第二安装板230的倾斜方向的顶端,且第二限位件设置于第一限位件的背离弹性件210的一侧,在发动机支架10、第一安装板220和弹性件210所构成的整体相对于第二安装板230沿第二安装板230的倾斜方向向下晃动时,第二限位件与第一限位件抵接,以减小弹性件210相对于第二安装板230和下横梁组件30沿第二安装板230的倾斜方向向下的晃动幅度,从而提高了弹性件210和隔振组件20的耐久性。Referring to FIGS. 1 and 3 , in some embodiments, the first limiting member may be disposed on the top end of the second mounting plate 230 along the inclination direction of the second mounting plate 230 , and the second limiting member may be disposed on the suspension support.

本实施例中的车辆,包括发动机和发动机悬置系统,发动机悬置系统包括隔振组件20和发动机支架10,通过在隔振组件20上设置第一限位件,在发动机支架10上设置第二限位件,第二限位件与第一限位件正对且间隔设置,在发动机支架10、第一安装板220和弹性件210所构成的整体相对于第二安装板230沿第二安装板230的倾斜方向晃动时,第二限位件与第一限位件抵接,以减小发动机支架10、第一安装板220和弹性件210所构成的整体相对于第二安装板230的晃动幅度,从而提高了弹性件210和隔振组件20的耐久性。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 .
