[0002] The existing automobile powertrain system includes an engine and an engine suspension mounting structure connected to the engine. The engine suspension mounting structure is arranged on the vehicle to connect the engine and the frame. In order to make the engine have a certain buffering support effect, an elastic member, such as a support block made of rubber material, is usually arranged on the engine suspension mounting structure.

[0003] For example, Chinese patent CN202022573450.3 discloses an engine suspension mounting frame and an engine suspension mounting assembly. The engine suspension mounting frame includes an engine side bracket, a frame side bracket and an engine suspension cushion; the engine suspension cushion includes an upper cover plate and a lower cover plate and an elastic member arranged between the upper cover plate and the lower cover plate; a first connecting member for connecting the engine side bracket is arranged on the side of the upper cover plate away from the elastic member; a second connecting member for connecting the frame side bracket is arranged on the side of the lower cover plate away from the elastic member, and the installation position and installation angle of the second connecting member and the frame side bracket are adjustable.

[0004] The elastic support member in the engine suspension mounting frame includes an upper cover plate, a lower cover plate and an elastic member arranged between the upper cover plate and the lower cover plate. When the elastic member is damaged and needs to be replaced, the engine needs to be disassembled and then the elastic member needs to be disassembled for replacement. The process is relatively cumbersome and takes a long time. Utility Model Content

[0005] The purpose of the utility model is to provide an engine suspension mounting structure, which can provide buffer support for the engine during driving through a rubber support block between the engine suspension mounting structure and the vehicle frame, thereby playing a certain protective role for the engine.

[0006] The support frame is a pair of camshafts, each of which is connected to a pair of camshafts, each of which has a U-shaped opening at its upper end and a horizontal plate at its lower end, each of which is connected to a suspension mounting plate extending upward for mounting the engine.

[0007] Preferably, a reinforcing rib plate is provided at the angle between the oblique connecting plate and the horizontal plate, one end of the reinforcing rib plate is fixedly connected to the limiting shell, and the other end of the reinforcing rib plate is fixedly connected to the suspension mounting plate.

[0008] Preferably, a plurality of weight-reducing holes are arranged transversely through the upper edge of the reinforcing rib plate.

[0009] Preferably, the oblique connecting plate, the frame mounting plate, the horizontal plate, the suspension mounting plate, the limiting shell and the reinforcing rib plate are an integral structure formed by integral casting.

[0010] Preferably, a first right-angle plate is fixedly connected to the matching position between the rubber support block and the right-angle limiting groove, and a second right-angle plate is fixedly connected to the lower corner position of the rubber support block on the side facing away from the suspension mounting plate.

[0011] Preferably, a first bolt screwed to the first right-angle plate is provided through the limiting housing, and a screw hole for screwing to the frame through the second bolt is provided on the vertical surface of the second right-angle plate.

[0012] Preferably, a plurality of oblique supporting ribs are provided between the outer side of the first right-angle plate and the bottom surface of the oblique connecting plate.

[0013] Preferably, the rubber support block, the first right-angle plate and the second right-angle plate are a vulcanized integrated structure.

[0014] Preferably, a plurality of first mounting holes are arranged on the frame mounting plate, and a first positioning ring coaxial with the first mounting holes is arranged on the outer side of the frame mounting plate.

[0015] Preferably, a plurality of second mounting holes are arranged on the suspension mounting plate, and a second positioning ring coaxial with the second mounting holes is arranged on the outer side of the suspension mounting plate.

[0016] The support frame is a pair of camshafts, each of which is connected to a pair of locking plates, each of which has a U-shaped groove and a bottom end, and the locking plates are connected to the support frame of the vehicle frame.

[0017] The installation method and beneficial effects of the engine suspension mounting structure are as follows: during installation, two symmetrically arranged engine suspension mounting structures are used to respectively install the two frame mounting plates to corresponding positions on the frames on both sides, and then the rubber support blocks are inserted from bottom to top into the right-angle limit grooves for installation and fixation, and then the two sides of the engine are installed on the two suspension mounting plates. After installation, the two ends of the rubber support blocks are respectively supported in the right-angle limit grooves and the sides of the frame to provide elastic support for the engine. The elastic coefficient of the rubber support blocks is selected according to needs. At the same time, through the setting of the rubber support blocks, a certain range of limiting effect is also played, so that the deformation angle between the oblique connecting plate and the frame mounting plate will not change too much, and the bending parts of the two will not break.

[0018] Since the rubber support block is inserted from bottom to top and installed between the frame and the right-angle limit groove, and has no connection with the engine, the rubber support block in the engine suspension mounting structure can be independently disassembled and replaced without disassembling the connection of the engine, which is convenient for later maintenance and replacement.

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0028] In the present utility model, unless otherwise stated, directional words contained in terms such as "up, down, left, right, front, back, inside, outside" merely represent the orientation of the terms in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0029] See also Figure 1-4 The engine suspension mounting structure shown in the figure comprises an oblique connecting plate 2, the upper end of the oblique connecting plate 2 is provided with a U-shaped opening 14, the lower end is connected with a horizontal plate 3, the end of the horizontal plate 3 facing away from the oblique connecting plate 2 is provided with an upwardly extending suspension mounting plate 4 for mounting the engine, the upper end of the oblique connecting plate 2 is located on both sides of the U-shaped opening 14 and is respectively connected with a downwardly extending frame mounting plate 1 for connecting the frame, the upper surface of the oblique connecting plate 2 is provided with a limiting shell 9, the bottom of the limiting shell 9 is provided with a right-angle limiting groove connected with the U-shaped opening 14, the side and the lower side of the right-angle limiting groove facing away from the suspension mounting plate 4 are both set to be open, a rubber support block 11 is inserted and installed in the opening from bottom to top, the side of the rubber support block 11 facing away from the suspension mounting plate 4 is set to be able to abut against the side of the frame, and the two sides of the rubber support block 11 are respectively detachably mounted on the frame and the limiting shell 9.

[0030] Through the implementation of the above technical solution, during installation, two symmetrically arranged engine suspension mounting structures are used to respectively install the two frame mounting plates 1 to the corresponding positions on the frames on both sides, and then the rubber support block 11 is inserted from bottom to top into the right-angle limit groove for installation and fixation, and then the two sides of the engine are installed on the two suspension mounting plates 4. After installation, the two ends of the rubber support block 11 are respectively supported in the right-angle limit groove and the side of the frame to provide elastic support for the engine. The elastic coefficient of the rubber support block 11 is selected according to needs. At the same time, through the setting of the rubber support block 11, a certain range of limiting effect is also played, so that the deformation angle between the oblique connecting plate 2 and the frame mounting plate 1 will not change too much, and the bending part of the two will not break.

[0031] The rubber support block 11 in the engine suspension installation structure can be independently disassembled and replaced without disassembling the connection part of the engine, which is convenient for later maintenance and replacement.

[0032] In this embodiment, in order to further increase the overall strength, a reinforcing rib plate 7 is provided at the angle between the oblique connecting plate 2 and the horizontal plate 3 , one end of the reinforcing rib plate 7 is fixedly connected to the limiting shell 9 , and the other end is fixedly connected to the suspension mounting plate 4 .

[0033] In this embodiment, in order to reduce the overall weight, a plurality of weight-reducing holes 8 are provided in the reinforcing rib plate 7 in a transverse direction.

[0034] In this embodiment, the oblique connecting plate 2, the frame mounting plate 1, the horizontal plate 3, the suspension mounting plate 4, the limiting shell 9 and the reinforcing rib plate 7 are an integral structure formed by integral casting.

[0035] Through such an arrangement, the overall strength is increased. In order to cooperate with the rubber support block 11 to produce corresponding elastic deformation when under pressure, the steel used in the one-piece casting structure should have a certain bending deformation ability, such as using spring steel. When the rubber support block 11 is able to produce corresponding elastic deformation when under pressure, the bending position of the oblique connecting plate 2 and the frame mounting plate 1 will also be compressed by a certain angle to follow the deformation, but the deformation amount is limited by the supporting effect of the rubber support block 11. Therefore, the angle compression change can be controlled within a safe range by controlling the elastic coefficient of the rubber support block 11.

[0036] In this embodiment, a first right-angle plate 17 is fixedly connected to the matching position of the rubber support block 11 and the right-angle limiting groove, and a second right-angle plate 12 is fixedly connected to the lower corner of the rubber support block 11 facing away from the suspension mounting plate 4 .

[0037] By providing the first right-angle plate 17 and the second right-angle plate 12 , the rubber support block 11 is prevented from directly contacting the limit housing 9 and the frame, thereby avoiding the problem of rapid wear of the rubber support block 11 due to direct contact.

[0038] In this embodiment, in order to further provide an assembly method for the rubber support block 11, a first bolt 10 screwed to the first right-angle plate 17 is provided through the limit shell 9, and a screw hole 16 for screwing to the frame through the second bolt is provided on the vertical surface of the second right-angle plate 12.

[0039] For example, two first bolts 10 symmetrically arranged on the left and right pass through the limiting housing 9 and are screwed onto the vertical panel of the first right angle plate 17 to fix the position of the first right angle plate 17 .

[0040] The second right-angle plate 12 is fixed by two second bolts symmetrically arranged through the frame and then screwed into the screw holes 16 on the vertical surface of the second right-angle plate 12. The entire buffering process relies on the extrusion deformation of the rubber support block 11.

[0041] In this embodiment, a plurality of oblique support ribs 18 are arranged between the outer side of the first right-angle plate 17 and the bottom surface of the oblique connecting plate 2. The arrangement of the plurality of oblique support ribs 18 further improves the support strength of the side surface of the first right-angle plate 17. The ends of the first right-angle plate 17 and the oblique support ribs 18 are connected by contact support, and the bottom surface of the oblique connecting plate 2 and the top surfaces of the plurality of oblique support ribs 18 are connected by welding or integral casting.

[0042] In this embodiment, in order to further provide a fixed connection structure between the rubber support block 11 and the first right-angle plate 17 and the second right-angle plate 12, the rubber support block 11 and the first right-angle plate 17 and the second right-angle plate 12 are a vulcanized integrated structure.

[0043] In this embodiment, the frame mounting plate 1 is provided with a plurality of first mounting holes 13, and the outer side of the frame mounting plate 1 is provided with a first positioning ring 15 coaxial with the first mounting hole 13. The first mounting hole 13 is used to pass a third bolt through to achieve connection with the frame, and the first positioning ring 15 cooperates with the corresponding first positioning groove on the frame to achieve rapid positioning.

[0044] In this embodiment, a plurality of second mounting holes 5 are provided on the suspension mounting plate 4, and a second positioning ring 6 coaxial with the second mounting hole 5 is provided on the outer side of the suspension mounting plate 4. The second mounting hole 5 is used to pass a fourth bolt to achieve connection with the engine, and the second positioning ring 6 cooperates with the corresponding second positioning groove on the engine to achieve rapid positioning.
