Description

Technical Field

[0001] The utility model relates to the technical field of automobile left suspension, in particular to an automobile left suspension bracket assembly. Background Art

[0002] The suspension is an automotive powertrain component used to reduce and control the transmission of engine vibration and play a supporting role. It is used in the current automotive industry. The widely used suspensions are divided into traditional pure rubber suspensions and hydraulic suspensions with better dynamic and static performances.

[0003] Chinese patent publication number CN209320664U provides a suspension support arm and an engine suspension. The suspension support arm of the utility model is connected between an inner core and an engine assembly, wherein: the inner core is surrounded by an inner core end wall and an inner core peripheral wall to form an arm mounting cavity with a press-fitting opening; the suspension support arm includes a press-fitting portion press-fitted into the arm mounting cavity, and the cross-section of the press-fitting portion follows the cross-section of the inner core peripheral wall; an uneven anti-slip portion is formed on the abutting surface of the press-fitting portion abutting against the inner core peripheral wall; and the suspension support arm also includes a connector arranged outside the arm mounting cavity, and an engine assembly connecting portion is constructed on the connector.

[0004] The above patent arranges an uneven anti-slip portion on the abutting surface of the press-fitting portion that abuts against the peripheral wall of the inner core to increase the friction between the press-fitting portion and the inner core, thereby achieving the purpose of reducing the risk of the suspension arm falling out and failing; and because the anti-slip portion is arranged, the tolerance requirements for the inner core can be reduced, thereby reducing the production cost.

[0005] However, in the above technology, when the press-fitting part and the circumferential wall of the inner core are installed with each other, the concave and convex parts are interlocked with each other, resulting in that the press-fitting part and the circumferential wall of the inner core need a large thrust, and one of the components needs to be deformed so that the press-fitting part can be inserted into the inner wall of the inner core. Therefore, the press-fitting part is inconvenient to install when inserted into the inner core, and the production cost of the uneven anti-slip part is relatively high during production. In addition, during use, the uneven anti-slip part will bear the vibration of the engine, causing the uneven anti-slip parts to wear each other, resulting in a lower service life of the suspension.

[0030] The inner core 6 includes a bottom shell 601 and an upper cover 602. Both sides of the bottom shell 601 and the upper cover 602 are provided with connecting holes 603. A threaded rod 604 is arranged inside the connecting hole 603, and both ends of the threaded rod 604 are respectively inserted into the inside of two opposite guide cylinders 5. The inner bottom wall of the bottom shell 601 is arranged as an inclined surface.

[0031] In this embodiment, when in use, the press-fitting portion 7 is inserted into the inner core 6, so that the press-fitting portion 7 is fixed inside the inner core 6, and the inner core 6 is installed inside the base 1 and the bridge bracket 2, and then one of the two suspension rubber main springs 3 is installed at a position between the bottom of the inner core 6 and the bottom wall inside the base 1, and the other is installed at a position between the top of the inner core 6 and the top of the bridge bracket 2 to support the inner core 6, thereby reducing the vertical vibration of the engine and preventing the engine from driving the frame to vibrate;

[0032] Specifically, the threaded rod 604 is provided to cooperate with the connecting hole 603 to close the bottom shell 601 and the upper cover 602 to each other, such as Figure 3 , and the bottom shell 601 and the upper cover 602 are clamped by two nuts to achieve the purpose of closing the bottom shell 601 and the upper cover 602. The bottom shell 601 and the upper cover 602 can be effectively aligned by the arrangement of the threaded rod 604, so as to improve the stability of the connection between the bottom shell 601 and the upper cover 602. After the bottom shell 601 and the upper cover 602 are aligned, the upper cover 602 is slightly lifted upward, and the press-fitting part 7 is inserted between the bottom shell 601 and the upper cover 602, and then the upper cover 602 is pushed to contact with the bottom shell 601, and the bottom shell 601 and the upper cover 602 are respectively locked by two nuts, as shown in FIG.

[0034] In a further preferred embodiment of the present invention, Figure 1-6As shown, the outer wall of the portion of the threaded rod 604 inserted into the guide cylinder 5 is smooth, and a rubber auxiliary spring is provided inside the guide cylinder 5.

[0035] In this embodiment, since the end of the threaded rod 604 inserted into the guide cylinder 5 is smooth, Figure 2 and 3 , and a rubber auxiliary spring is arranged inside the guide cylinder 5, so that when the device is subjected to the vibration of the engine, the inner core 6 can move up and down to prevent the vibration of the engine from being transmitted to the frame, causing abnormal noise of the frame or excessive shaking of the frame, and cooperate with the setting of two suspended rubber main springs 3 installed at the bottom end of the bottom shell 601 and the upper end of the upper cover 602 to further improve the shock absorption capacity of the inner core 6 to the engine vibration.

[0036] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the bottom end of the press-fitting portion 7 is arranged as an inclined surface, and the inclination angle is equal to the inclination angle of the inner bottom wall of the bottom shell 601 .
