[0026] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0027] Reference below Figure 1-Figure 4 A suspended support beam 100 according to an embodiment of the present invention is described, and the present invention also provides a vehicle.

[0028] Reference Figure 1-4 As shown, the suspension support beam 100 of the embodiment of the utility model has one end fixedly connected to the suspension and the other end fixedly connected to the engine. The suspension support beam 100 includes: a top plate 10 and two side plates 20, the two side plates 20 are arranged on both sides of the top plate 10, and the top plate 10 and the side plates 20 form a box-shaped structure. Specifically, one end of the suspension support beam 100 is fixedly connected to the suspension cushion, and the other end is fixedly connected to the engine. The main body of the suspension support beam 100 is composed of the top plate 10 and the side plates 20 on the left and right sides of the top plate 10. The top plate 10 and the side plates 20 form a box-shaped structure with uniform wall thickness, which is convenient for casting and reduces the occurrence of casting defects. Moreover, since the wall thickness of the suspension support beam 100 is uniform, various structures such as slots and holes are reduced, and the weight can be lighter than the traditional suspension support beam 100 while ensuring strength, and 5% weight reduction can be achieved, so that the manufacturing cost is reduced.

[0029] Therefore, by setting the suspension support beam 100 as a box-shaped structure, it is easy to cast and reduce the occurrence of casting defects. While ensuring the strength, it is lighter than the traditional suspension support beam 100, which can achieve a 5% weight reduction and reduce the manufacturing cost.

[0030] Reference Figure 1-4 As shown, one of the side panels 20 is provided with a cambered surface 21 on the side facing the engine, and the cambered surface 21 is used to avoid the engine. Since the engine accessories are partially protruding, the side panel 20 on the side of the suspension support beam 100 close to the engine is designed with a certain offset distance, so that the side panel 20 and the positions on both sides fixed with the engine and the suspension form the cambered surface 21 to meet the assembly requirements of the suspension support beam 100 and the engine.

[0031] Reference Figure 1-4As shown, a first connection portion 30 is provided at one end of the suspension support beam 100, and the first connection portion 30 is used to be fixedly connected to the suspension, and a second connection portion 31 is provided at the other end of the suspension support beam 100, and the second connection portion 31 is used to be fixedly connected to the engine. That is, the suspension support beam 100 is connected to the suspension cushion through the first connection portion 30, and is fixedly connected to the engine at the other end through the second connection portion 31, so as to ensure the driving stability of the vehicle.

[0032] Reference Figure 1-4 As shown, in the left-right direction of the suspension support beam 100, the plurality of first connection parts 30 are offset relative to the second connection part 31. In order to avoid the protruding part of the engine accessories, the side plate 20 of the suspension support beam 100 close to the engine is designed with a certain offset distance, so that the side plate 20 and the positions on both sides fixed with the engine and the suspension form an avoidance arc surface 21, and the offset of the side plate 20 causes the plurality of first connection parts 30 to be offset relative to the second connection part 31, so as to meet the assembly requirements of the suspension support beam 100 and the engine.

[0033] Reference Figure 1-4 As shown, the first connection part 30 is provided with a plurality of first mounting holes 301, and the first mounting holes 301 are used to be fixedly connected to the suspension; and the second connection part 31 is provided with a plurality of second mounting holes 311, and the second mounting holes 311 are used to be fixedly connected to the engine. That is, at the first connection part 30, the suspension support beam 100 can be fixedly connected to the suspension cushion by fasteners passing through the first mounting holes 301, wherein the first mounting holes 301 can be two. At the second connection part 31, the fasteners pass through the second mounting holes 311 to fix the suspension support beam 100 and the engine, wherein the second mounting holes 311 can be four.

[0034] Reference Figure 1-4 As shown, a plurality of avoidance grooves 22 are provided on the side plate 20, and the avoidance grooves 22 correspond to the second mounting hole 311. Specifically, a plurality of avoidance grooves 22 are provided near the second mounting hole 311 of the side plate 20, and the plurality of avoidance grooves 22 reserve sufficient space for fasteners to pass through the second mounting hole 311, thereby preventing wear caused by friction of parts during assembly, and the avoidance grooves 22 fully utilize the space of the side plate 20, thereby making the structure of the suspension support beam 100 more compact and reasonable, and reducing weight and production costs.

[0035] Reference Figure 1-4As shown, the top plate 10 includes: a first part 101 and a second part 102, the first part 101 and the second part 102 are connected, and in the length direction of the suspension support beam 100, the cross-sectional area of ​​the first part 101 gradually decreases and the cross-sectional area of ​​the second part 102 gradually increases. That is. The top plate 10 is designed to be an irregular shape, and the connection between the first part 101 and the second part 102 is the smallest cross-sectional area. On the one hand, the smallest cross-sectional area matches the position of the avoidance arc surface 21 of the side plate 20, which meets the basic requirements of the structural design and makes the overall structure more stable. On the other hand, it can reduce the use of structural materials while meeting the strength of the suspension support beam 100, thereby reducing the overall weight of the suspension support beam 100.

[0036] Reference Figure 1-4 As shown, at least one side plate 20 is tilted on the top plate 10. The side plate 20 is tilted relative to the top plate 10 to enhance the structural stability of the suspension support beam 100. In particular, when facing lateral forces, the tilted side plate 20 has better strength, which reduces the load of the top plate 10 to a certain extent and improves the strength of the suspension support beam 100.

[0037] The vehicle according to the second embodiment of the utility model comprises: a frame, an engine, a suspension and a suspension support beam 100. The engine and the frame are arranged at intervals, the suspension is fixed on the frame, one end of the suspension support beam 100 is fixedly connected to the suspension and the other end is fixedly connected to the engine. That is, one end of the suspension support beam 100 can be fixed to the frame after being connected to the suspension cushion, and the other end is fixedly connected to the engine, so as to achieve stable operation of the vehicle.
