[0037] The first direction X, the second direction Y, and the third direction Z herein are directions that are each intersecting with one another.

[0038] An embodiment of the present disclosure provides a vehicle. The vehicle can be a car, an engineering vehicle, a truck, or the like. The vehicle can include a main frame, a sub-frame, a steering machine, an axle, a suspension, a vehicle body, and an exhaust pipe. The main frame can be connected to the steering machine, the axle, the suspension, the vehicle body, and the exhaust pipe through the sub-frame, respectively, and the connection manner can be welding or bolting, so as to serve as a support structure of the vehicle.

[0039] In the existing vehicle, the exhaust pipe is arranged at the bottom of the sub-frame, and the sub-frame is provided with an avoiding groove for accommodating the exhaust pipe. However, the strength of the area of the sub-frame provided with the avoiding groove is low, and after the steering machine is installed, the constraint mode of the sub-frame is too low (for example, the constraint mode of the sub-frame is 100 Hz), which affects the reliability of the whole vehicle.

[0040] To solve the above problems, in an embodiment of the present disclosure, referring to Figures 1-5The vehicle comprises a subframe and a steering machine. The subframe comprises a frame body 1, one side of the frame body 1 is provided with a clearance groove 111 extending along a first direction X and penetrating through the frame body 1, the frame body 1 has a plurality of first connecting holes 13 and at least one second connecting hole 14, at least two first connecting holes 13 are located on both sides of the clearance groove 111, and the distance between the second connecting hole 14 and the clearance groove 111 along a second direction Y is less than the distance between the first connecting hole 13 and the clearance groove 111 along the second direction Y. The steering machine is arranged on the frame body 1 and comprises a base 2 connected with the first connecting hole 13 and the second connecting hole 14 through a mounting member respectively.

[0041] In the embodiment of the present disclosure, the clearance groove 111 is arranged on one side of the frame body 1, and the exhaust pipe can be arranged in the clearance groove 111, thereby reducing the space occupied by the exhaust pipe. In the vehicle of the embodiment of the present disclosure, the base 2 of the steering machine is connected with the first connecting hole 13 and the second connecting hole 14 through the mounting member respectively, and the distance between the second connecting hole 14 and the clearance groove 111 is less than the distance between the first connecting hole 13 and the clearance groove 111, so that the second connecting hole 14 is closer to the clearance groove 111 than the first connecting hole 13. After the steering machine is installed on the frame body 1, the area around the clearance groove 111 of the frame body 1 is improved in bending resistance by the rigidity of the base 2 due to the existence of the mounting point of the base 2 of the steering machine, which is beneficial to the improvement of the constraint mode of the subframe and the reliability of the vehicle.

[0042] In an embodiment of the present disclosure, referring to Figure 3 、 Figure 5 、 Figure 6 The frame body 1 comprises a buckling-welded bottom plate 11 and a top plate 12, the top plate 12 is stacked on the bottom plate 11, and a cavity is formed between the bottom plate 11 and the top plate 12 to reduce the weight of the frame body 1. The clearance groove 111 is arranged on the side of the bottom plate 11 away from the top plate 12, and the groove bottom of the clearance groove 111 is protruded towards the top plate 12 to make the thickness of the bottom plate 11 consistent. The bottom plate 11 has first folding edges on both sides of the clearance groove 111, and the two first folding edges are folded along the side of the bottom plate 11 away from the clearance groove 111, and the folding angle of the first folding edge can be not more than 90°. The top plate 12 can have two second folding edges (not shown in the drawings) along the first direction X, and the two second folding edges are located on both sides of the top plate 12 along the second direction Y and are folded towards the side of the bottom plate 11.

[0043] In an embodiment of the present disclosure, referring to Figure 1 、 Figure 3 、 Figure 5, the number of the first connecting holes 13 is two, and the two first connecting holes 13 are distributed on the two sides of the avoiding groove 111 along the second direction Y.

The power-assisted part 7 is further included, and the centroid of the power-assisted part 7 in the first plane projects on a line with the projections of the first connecting holes 13 and the second connecting hole 14 in the first plane at a distance less than or equal to a first preset value. The first preset value is 15 mm, and the first plane is a plane formed by the first direction and the second direction. For example, the distance between the centroid of the power-assisted part 7 in the first plane and the line formed by the projections of the first connecting holes 13 and the second connecting hole 14 in the first plane can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm or 15 mm. In another embodiment of the present disclosure, the line formed by the first connecting holes 13 and the second connecting hole 14 on the same side of the avoiding groove 111 projects on the first plane to cover the centroid of the power-assisted part 7 in the first plane.
