Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and particularly relates to an automobile front leaf spring hanger bracket assembly. Background Art

[0002] An automobile suspension is a device that elastically connects the vehicle frame and the axle in an automobile. It is divided into a front suspension and a rear suspension in the automobile and mainly consists of three parts: an elastic element, a shock absorber, and a guiding device, which play the roles of shock absorption, buffering, and guiding respectively. Among them, the elastic element is used to elastically connect the vehicle frame (or body) with the axle or wheel, bear and transmit loads, and relieve impacts. The leaf spring is the most traditional elastic element in the automobile suspension and is generally used for non-independent suspensions. Among them, the leaf spring hanger bracket plays an important role in the connection between the leaf spring and the vehicle frame. The front leaf spring hanger brackets of common commercial vehicles are of two types: stamping sheet metal parts and castings, and the castings are the most common. The existing structure of the front leaf spring hanger bracket is mainly adapted to a non-variable cross-section beam vehicle frame and is integrally formed by a casting process. It is installed below the vehicle frame cross beam and cannot adapt to a variable cross-section beam vehicle frame. Although the cast leaf spring hanger bracket is beneficial to the installation strength of the front leaf spring, it requires the development of a mold and the cost is relatively high.

[0003] Therefore, an automobile front leaf spring hanger bracket assembly with the publication number of "CN221250462U" includes a vehicle frame mounting component, which includes two first mounting plates arranged in the same plane. The first mounting plate is provided with a first mounting hole, and the first mounting hole is used to realize the connection and fixation with the side surface of the vehicle frame cross beam; a front hanger mounting component, which includes a first vertical plate and a second vertical plate arranged in parallel. Among them, the first vertical plate is provided with a second mounting hole, and the second vertical plate is provided with a pin shaft through hole. The front hanger mounting component is used to realize the fixed connection of the front leaf spring pin shaft; among them, the front hanger mounting component is fixedly connected to the lower part of the vehicle frame mounting component. It solves the problems in the prior art that the integrally formed casting structure has a high cost and cannot adapt to a variable cross-section beam vehicle frame. The front leaf spring can be installed on the side of the vehicle frame cross beam, while meeting the strength of the installation point, being convenient to process, having strong part replaceability, and low production cost.

[0004] However, for the above-mentioned front leaf spring hanger bracket assembly of an automobile, although the riveting holes are provided on one of the first mounting plates, the bolt holes are provided on the other first mounting plate, and the riveting holes and the bolt holes are symmetrically arranged along the central axis of the vehicle frame mounting assembly. Among them, the riveting holes are used to connect rivets to completely fix the bracket assembly to the vehicle frame and provide installation strength. However, there are still the following obvious defects during use: However, when the bracket assembly is fixed by using the first mounting plate through the vehicle frame mounting assembly, since the surface of the first mounting plate in contact with the vehicle frame is a smooth surface, after the first mounting plate is fixedly connected to the vehicle frame, due to the large load that the vehicle frame needs to bear during the use of the automobile, the position of the fixed connection of the bracket will shift under the long-term gravity support of the vehicle frame when the gravity is large. Utility Model Content

The frame mounting plate is located above the front hanger reinforcing plate and forms a right-angle mounting structure, which is conducive to larger-area contact with the frame for locking and fixing, and increases the support strength between the frame and the frame.

[0014] Compared with the prior art, the technical effects and advantages of the present invention are as follows: for the front leaf spring hanger bracket assembly of the automobile, through the front hanger reinforcing plate provided on one side of the front hanger mounting part, the anti-slip locking blocks on one side of the front hanger reinforcing plate, and the frame mounting plate integrally provided on the frame mounting part, as well as the integrally formed locking anti-slip blocks on the surface of the frame mounting plate, when the front hanger reinforcing plate and the frame mounting plate are locked and installed on the automobile frame, the strength of the locking bolt is used to press the anti-slip locking blocks and the locking anti-slip blocks on the front hanger reinforcing plate and the frame mounting plate against the mounting surface of the automobile frame, so that a certain locking and grasping strength is generated between the anti-slip locking blocks, the locking anti-slip blocks and the automobile frame, making the connection between the front hanger reinforcing plate and the frame mounting plate and the automobile frame more firm and stable. Therefore, after the front hanger mounting part and the frame mounting part are installed, the leaf spring and the frame are stably supported, and the problem that the fixed connection position may shift under the action of the large gravity when the frame is supported by the long-term load of the automobile can be avoided.

[0015] Through the integrally formed reinforcing connecting plate at the connection between the frame mounting part and the front hanger mounting part, and the reinforcing connecting plate is integrally welded at the top of the inner part of the front hanger mounting, the fixed support surface of the frame mounting part at the end of the front hanger mounting part becomes larger, making the support of the frame mounting part more firm after being fixedly connected to the automobile frame. Therefore, the situation that the support surface of the front hanger mounting part is concave and deformed due to the large downward pressure of the automobile load on the frame mounting part will not occur, and the strength of the automobile frame load support is further enhanced.
