Detailed Description
The utility model provides a power assembly linking bridge, support body 10 upper portion has the suspension connecting portion 11 of being connected with suspension support 1 cooperation, support body 10 lower part has assembly body connecting portion 12 of connecting the power assembly body, it wears the connecting bolt to be used for connecting suspension support 1 to have the connecting hole between the upper and lower terminal surface of this suspension connecting portion 11, assembly body connecting portion 12 is including being located the linkage unit of high low dislocation position arrangement, set up bolted connection hole between the upper and lower terminal surface of linkage unit, cell wall 15 and tank bottom that constitute by curved surface form gusset between suspension connecting portion 11 and assembly body connecting portion 12 are connected each connecting hole and/or bolted connection hole, cell wall 15 and tank bottom enclose regional uncovered directional downwards.
The scheme is suitable for connecting supports connected with a power assembly at each position on a vehicle, in particular to a connecting support connected with the power assembly and suspended at the left side of a gearbox, wherein a support body 10 is connected with the suspended support 1 and the power assembly through bolts, because the structure of the power assembly is complex, connecting units with high and low dislocation positions can be respectively connected with different connecting surfaces with high and low dislocation positions on the power assembly, the distribution distance of each connecting unit is effectively improved, the area of the power assembly subjected to the suspending force is increased, the stress concentration is reduced, the shearing force direction of the bolts on each connecting unit is not positioned on the same plane when the bolts on each connecting unit are subjected to shearing force, the stress concentration at the bolts is also avoided, meanwhile, the groove wall 15 and the groove bottom formed by curved rib plates avoid the material fragile sections with large break angles formed by the high and low dislocation positions, and the structural strength of the connecting supports is effectively improved, meanwhile, the bracket body 10 in the groove-shaped structure reduces the weight of the bracket body while ensuring the structural strength.
The assembly body connecting part 12 is surrounded at the peripheral area of the area where the suspension connecting part 11 is located, and the area where the suspension connecting part 11 is located is higher than the area where the assembly body connecting part 12 is located. Thus, the suspension, the connecting bracket and the power assembly form a suspension type suspension instead of a supporting type suspension.
The upper end of the suspension connecting part 11 comprises three circular table parts 111 with table surfaces located on the same horizontal plane, one of the circular table parts 111 is provided with a fixing bolt 112, the other two circular table parts are provided with first and second connecting holes 113 and 114 with hole cores vertically arranged, and an isosceles or equilateral triangle is formed among the first and second connecting holes 113 and 114 and the fixing bolt 112. The three circular table parts 111 with the table surfaces positioned on the same horizontal plane are convenient to process and manufacture, the upper end surface and the lower end surface of the dislocation connecting unit can be processed by taking the surfaces as references, the overall processing difficulty of the connecting support is reduced, and the connecting support is small in stress and high in structural strength, and bolts are not prone to fracture. When the connecting bracket is installed, the connecting bracket and the suspension bracket can be initially positioned in the mounting hole through the fixing bolt 112, and then the nut of the fixing bolt 112 is screwed. The connecting holes 113 and the connecting line of the shaft cores of the fixing bolts 112 form an isosceles or equilateral triangle, wherein the angle of the shaft core of the fixing bolt 112 is taken as a vertex angle, the vertex angle is less than or equal to 60 degrees, and the connecting line of the shaft axis between the two connecting holes 113 and the connecting line of the shaft cores of the fixing bolts 112 ensure that the stress of the connecting bolts on the circular table part 111 is balanced and the situation that one bolt is stressed greatly and is broken is prevented.
The assembly body connecting portion 12 includes first, second, and third connecting units 121, 122, 123, and the first, second, and third connecting units 121, 122, 123 are tubular and have their lower end surfaces parallel to each other. The parallel end surfaces facilitate simultaneous machining with reference to the table surface of the circular table portion 111.
The bolt connecting hole cores of the first, second and third connecting units 121, 122 and 123 form a V-shaped region with the bolt connecting hole core of the second connecting unit 122 as a vertex angle, and the fixing bolt 112 is located in the V-shaped region. The vertical suspension force of the suspension connecting part 11 is approximately positioned in or near the V-shaped area formed between the connecting units, so that the horizontal distances of the suspension forces of the upper end and the lower end of the bracket body 10 are relatively close, the phenomenon that the force of the upper end and the lower end is staggered relatively far to form an increased bending moment on the bracket body 10 is prevented, and the structural strength of the bracket body 10 is further ensured.
A reinforcing rib is arranged on the inner bottom of the bracket body 10 between the first connecting unit 121 and the root of the fixing bolt 112, a bottom center line in the isosceles or equilateral triangle is positioned on the reinforcing rib, and a reinforcing rib is arranged on the inner bottom of the bracket body 10 between the second and third connecting units 122 and 123 and the root of the fixing bolt 112. The structural strength of the bracket body 10 is increased by the reinforcing ribs 14 connected to the connecting units without forming holes at the root of the fixing bolts 112, and the structural strength of the boss parts 111 at both sides of the reinforcing ribs 14 is substantially matched by the reinforcing ribs 14 between the first connecting unit 121 and the fixing bolts 112 being positioned at the middle positions of the first and second connecting holes 113 and 114.
The bolt coupling hole provided between the upper and lower end surfaces of the first coupling unit 121 located at the lowest position is a kidney-shaped hole. The waist-shaped hole is arranged to facilitate the installation and positioning between the connecting unit 121 and the power assembly.
The groove walls 15 between the outer wall of the first connecting unit 121 and the outer wall of the circular table portion 111 where the first connecting hole 113 is located, between the outer wall of the first connecting unit 121 and the outer wall of the circular table portion 111 where the second connecting hole 114 is located, between the outer wall of the circular table portion 111 where the first connecting hole 113 is located and the outer wall of the third connecting unit 123, between the outer wall of the second connecting unit 122 and the outer wall of the third connecting unit 123, and between the outer wall of the second connecting unit 122 and the outer wall of the circular table portion 111 where the second connecting hole 114 is located are arc curved rib plates with curvature axes located outside the groove cavity, and the upper edge and the lower edge of the groove wall 15 are arranged along a staggered pattern. That is, the upper and lower edges of the slot wall 15 are substantially the same in size, but the upper and lower edges are the curves arranged along the length so that the two ends of the slot wall are connected to the adjacent connecting units, thereby effectively reducing the size of the cavity of the bracket body 10, improving the structural strength, reducing the use of materials and reducing the weight of the bracket body 10.
The bracket body 10 is formed by casting. Since the stent body 10 has a structure with many curved surfaces and is not easily press-molded, it is made of cast iron alloy or aluminum alloy.
