According to the balance shaft support 1 of the embodiment of the utility model, the first lightening hole 130, the second lightening hole 140 and the third lightening hole 150 which penetrate through the main body 100 along the thickness direction are arranged on the main body 100, the second lightening hole 140 and the third lightening hole 150 are respectively arranged at two sides of the first lightening hole 130 in the width direction of the main body 100 and are positioned below the first lightening hole 130, and the first lightening hole 130, the second lightening hole 140 and the third lightening hole 150 are arranged at intervals, so that the first lightening hole 130, the second lightening hole 140 and the third lightening hole 150 are arranged at different parts of the main body 100, the phenomenon that the pore diameter of a single lightening hole is too large to greatly reduce the local structural strength of the balance shaft support 1 can be avoided, the overall structural strength of the balance shaft support 1 is high, the structure is not easy to damage, meanwhile, the plurality of lightening holes can perform shaft support for different parts of the balance shaft support 1, the mass distribution of the balance shaft support 1 is more uniform, and further contributes to the improvement of the structural strength of the balance shaft support 1.

Moreover, the mass of the balance shaft support 1 can be greatly reduced through the plurality of lightening holes, so that the balance shaft support 1 can meet the requirement of light weight, the weight is lighter, and the requirements of energy conservation, emission reduction and oil consumption reduction can be met.

In addition, the balance shaft 200 is connected with the first side surface 110 and extends in a direction far away from the main body 100, the balance shaft 200 is positioned right below the first lightening hole 130 and positioned below the side of the second lightening hole 140 and below the side of the third lightening hole 150, so that the balance shaft 200 is close to the first lightening hole 130, the second lightening hole 140 and the third lightening hole 150, the plurality of lightening holes can lighten the part where the balance shaft 200 is positioned, the weight of the balance shaft 200 is prevented from being excessively concentrated, in addition, the balance shaft 200 is suitable for being connected with a plate spring assembly, the relative displacement between the balance shaft support 1 and the plate spring assembly can be avoided, and the balance shaft support 1 and the plate spring assembly can jointly bear the load of a suspension,

Thus, the balance shaft support 1 according to the embodiment of the present invention has the advantages of light weight, reasonable layout, high structural strength, and the like.

In some embodiments of the present invention, as shown in fig. 1, the lowest point of the lower inner wall of the first lightening hole 130, the upper inner wall of the second lightening hole 140 and the upper inner wall of the third lightening hole 150 are located on the same plane.

Therefore, on one hand, the first lightening holes 130, the second lightening holes 140 and the third lightening holes 150 can be more reasonably arranged, a plurality of lightening holes can not occupy a large space of the main body 100 in the length direction of the main body 100, on the other hand, the superposition of the plurality of lightening holes in the length direction of the main body 100 can be avoided, and the structural strength of the balance shaft support 1 can be ensured.

In some embodiments of the present invention, as shown in fig. 1, the first lightening hole 130 includes a first main section 131, a first constricted section 132 and a second constricted section 133.

Specifically, the inner walls of the first main section 131 on the two opposite sides in the width direction of the main body 100 are parallel, the first contracting section 132 is communicated with the upper side of the first main section 131, the distance between the inner walls of the first contracting section 132 on the two opposite sides in the width direction of the main body 100 is gradually reduced towards the direction away from the first main section 131, the second contracting section 133 is communicated with the lower side of the first main section 131, and the distance between the inner walls of the second contracting section 133 on the two opposite sides in the width direction of the main body 100 is gradually reduced towards the direction away from the first main section 131.

Wherein, the upper end of the first contracting portion 132 may have an arc transition, and the lower end of the second contracting portion 133 may have an arc transition.

It can be understood that the cross-sectional area of the first main section 131 is larger, so that the mass of the balance shaft support 1 can be greatly reduced, the first contracted section 132 and the second contracted section 133 can prevent the stress concentration from occurring at the two ends of the first lightening hole 130 in the vertical direction, and prevent the deformation of the first lightening hole 130 when the balance shaft support 1 bears a load, so that the structural strength of the balance shaft support 1 is higher, and the service life is longer.

In some embodiments of the present invention, as shown in fig. 1, the second lightening hole 140 includes a second main section 141 and a first inclined section 142, inner walls of the second main section 141 are parallel to each other at opposite sides of the width direction of the main body 100, the first inclined section 142 communicates with a lower side of the second main section 141, and an inner wall of the first inclined section 142 away from the third lightening hole 150 is gradually inclined from top to bottom toward the third lightening hole 150.

Also, the third lightening hole 150 includes a third main section 151 and a second inclined section 152, the inner walls of the third main section 151 on opposite sides in the width direction of the body 100 are parallel, the second inclined section 152 communicates with the lower side of the third main section 151, and the inner wall of the second inclined section 152 far from the second lightening hole 140 is inclined from top to bottom gradually toward the second lightening hole 140.

It should be noted that the width of the main body 100 is gradually reduced from top to bottom, that is, the width of the upper side of the main body 100 is wider, so that the main body 100 and the frame can be conveniently connected to improve the connection strength between the main body 100 and the frame, and the width of the lower side of the main body 100 is gradually reduced to avoid the excessive volume of the balance shaft support 1.

Therefore, the mass of the balance shaft support 1 can be greatly reduced by the second main section 141 of the second lightening hole 140 and the third main section 151 of the third lightening hole 150, the first inclined section 142 can prevent the side of the second lightening hole 140, which faces away from the third lightening hole 150, from being too close to the side of the main body 100, and the second inclined section 152 can prevent the side of the third lightening hole 150, which faces away from the second lightening hole 140, from being too close to the side of the main body 100, so that the structural strength of the side of the main body 100 is prevented from being reduced, and the structural arrangement is more reasonable.

In some embodiments of the present invention, as shown in fig. 1, the first side 110 is provided with a base 300, the balance shaft 200 is mounted on the base 300, the cross-sectional area of the base 300 is larger than that of the balance shaft 200 and the central axis coincides with the central axis of the balance shaft 200,

specifically, the base 300 protrudes from the surface of the main body 100, and the cross-sectional area of the base 300 is larger than that of the balance shaft 200, so that the base 300 can play a transition role while being connected with the balance shaft 200, and the connection between the balance shaft 200 and the main body 100 is more reliable.

In addition, the highest point of the base 300 is higher than the lowest point of the second lightening hole 140 and the lowest point of the third lightening hole 150 and lower than the lowest point of the first lightening hole 130, and the axis of the base 300 is lower than the lowest point of the second lightening hole 140 and the lowest point of the third lightening hole 150.

In this way, the first lightening holes 130, the second lightening holes 140 and the third lightening holes 150 are all close to the base 300 and do not completely surround the base 300, so that on one hand, the mass around the base 300 can be reduced more, and the mass near the base 300 is prevented from being too concentrated, on the other hand, the structural strength at the base 300 can be prevented from being reduced too much, and therefore the overall structural strength of the balance shaft support 1 is ensured to be high.

In some embodiments of the present invention, as shown in fig. 1, the hole walls of the first lightening holes 130 protrude from the second side 120 of the main body 100, wherein the hole walls of the first lightening holes 130 may be formed by die casting, so that the hole walls of the first lightening holes 130 form recesses at the first side 110 of the main body 100.

The first through hole 210 and the second through hole 160 may also reduce the weight of the balance shaft support 1, further reducing the mass of the balance shaft support 1, and the reinforcing protrusion 121 may increase the structural strength of the main body 100 at the balance shaft 200, so as to increase the connection strength between the main body 100 and the balance shaft 200.

In some embodiments of the present invention, as shown in fig. 1-3, the main body 100 includes a balance shaft connection 101, a stringer connection 102, a thrust rod connection 103, and a connecting beam connection 104.

And, the thrust rod connecting part 103 is connected with the lower side of the balance shaft connecting part 101, the thrust rod connecting part is suitable for being connected with the thrust rod, and the thrust rod is matched with the balance shaft support 1, so that the torsion between the wheel and the vehicle body can be transferred, and meanwhile, the quality of the vehicle body can be carried, and the stability of the vehicle body can be ensured.

The first lightening holes 130 are formed in the longitudinal beam connecting portion 102, and the second lightening holes 140 and the third lightening holes 150 are formed in the balance shaft connecting portion 101, so that the first lightening holes 130 can lighten the longitudinal beam connecting portion 102, and the second lightening holes 140 and the third lightening holes 150 can lighten the balance shaft connecting portion 101, that is, a plurality of lightening holes can lighten different parts of the balance shaft support 1, the position distribution is more reasonable, and the structural strength of the balance shaft support 1 cannot be greatly damaged while lightening.
