Description

Technical Field

[0001] The utility model relates to an engine suspension, in particular to an inclined engine front suspension with a limiting structure. Background Art

[0002] At present, in the automotive industry, with the higher requirements for the life of the whole vehicle, the requirements for the service life of the suspension have become higher. At present, the front suspension of the engine of medium and light trucks in China mainly adopts sheet metal structure. The sheet metal structure product is light in weight but has no limit device. The product is easy to tear and thus affects the operation of the whole vehicle. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide a tilting engine front suspension with a limiting structure.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a tilted engine front suspension with a limiting structure, including an upper frame and a lower frame that are arranged obliquely, a suspension rubber body is supported between the upper frame and the lower frame, and one end of the upper frame is located in a C-shaped limiting structure at the same end of the lower frame.

[0005] Furthermore, the C-shaped limiting structure is located at the oblique upper end of the lower frame, and a horizontal middle limiting frame is arranged at the oblique upper end of the upper frame. The C-shaped limiting structure includes an upper limiting frame located at the top, a side limiting frame located at one side, and a lower limiting frame located at the bottom, and the middle limiting frame is located between the upper limiting frame and the lower limiting frame.

[0006] Furthermore, an upper limit rubber body is provided on the upper surface of the middle limit frame, a lower limit rubber body is provided on the bottom, and a side limit rubber body is provided at the end of the middle limit frame, so that the upper and lower parts and the sides of the middle limit frame correspond to each side of the C-shaped limit structure through the rubber body.

[0007] Furthermore, a fixing block with a triangular cross section is arranged at the center of the upper surface of the upper frame, the upper surface of the fixing block is horizontal, and is provided with a mounting threaded hole.

[0008] Furthermore, the outer vertical side wall of the C-shaped limiting structure is provided with horizontal fixing threaded holes arranged up and down.

[0009] Furthermore, a vertical positioning pin is also provided on the upper surface of the fixing block.

[0010] Furthermore, the cross-sections of the outer side surfaces of the upper limit rubber body, the lower limit rubber body and the side limit rubber body are wavy.

[0011] Through the above arrangement, the overall structure of the utility model is simple and compact. By optimizing the limiting structure between the upper frame and the lower frame, the limiting structure is a C-shaped limiting structure. The C-shaped limiting structure has an upper limiting frame, a side limiting frame located on one side and a lower limiting frame located at the bottom. The middle limiting frame is located between the upper limiting frame and the lower limiting frame, and the corresponding surfaces of the middle limiting frame and the C-shaped limiting structure are respectively provided with buffering limiting rubber bodies, which not only greatly reduces the wear of the upper limiting frame and the lower limiting frame, greatly improves the smoothness and safety of the car, but also has a more solid structure. The automobile factory using the utility model does not need to assemble the passive end bracket of the engine suspension. While ensuring that the cost remains unchanged, the fatigue life of the utility model is at least doubled that of the existing sheet metal structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The utility model is now further described with reference to the accompanying drawings.

[0014] like Figure 1 As shown, a tilted engine front suspension with a limiting structure includes an upper frame 1 and a lower frame 2 that are tilted, a suspension rubber body 3 is supported between the upper frame 1 and the lower frame 2, one end of the upper frame 1 is located in a C-shaped limiting structure 4 at the same end of the lower frame 2, and the upper frame 1, the suspension rubber body 3, and the lower frame 2 are vulcanized together through a vulcanization mold to form a suspension body.

[0015] Specifically: the C-shaped limiting structure 4 is located at the oblique upper end of the lower frame 2, and a horizontal middle limiting frame 101 is provided at the oblique upper end of the upper frame 1. The C-shaped limiting structure 4 includes an upper limit frame 401 located at the top, a side limiting frame 402 located at one side, and a lower limit frame 403 located at the bottom. The middle limiting frame 101 is located between the upper limit frame 401 and the lower limit frame 403.

[0016] An upper limit rubber body 102 is provided on the upper surface of the middle limit skeleton 101, a lower limit rubber body 103 is provided on the bottom, and a side limit rubber body 104 is provided on the end of the middle limit skeleton 101, so that the upper and lower parts and the side parts of the middle limit skeleton 101 correspond to each side of the C-shaped limit structure 4 through the rubber bodies, and the outer side cross-sections of the upper limit rubber body 102, the lower limit rubber body 103 and the side limit rubber body 104 are wavy.

[0017] In addition, in order to facilitate the installation and fixation of the utility model, a fixing block 5 with a triangular cross-section is arranged at the center of the upper surface of the upper frame 1.
