Description

Technical Field

[0001] The utility model belongs to the technical field of heavy trucks, and in particular relates to a crossbeam structure of a balance shaft support of a heavy truck. Background Art

[0002] When the balance shaft of a heavy truck is a split structure, when the heavy truck is running under heavy load, outward tension will be generated at the bottom of the balance shafts on both sides. The direction of the tension is perpendicular to the direction of the vehicle beam, which can easily lead to cracking of the vehicle beam and the frame crossbeam. The connection between the balance shaft and the frame is prone to breakage. In addition, the supports at both ends of the balance shaft are severely worn. Therefore, a heavy truck balance shaft support crossbeam structure should be provided. Utility Model Content

[0022] like Figure 1 and Figure 2 As shown, the utility model includes a balancing shaft 1, a front thrust rod 5, a rear thrust rod 6 and a support beam installed under the two supports 1-1 of the balancing shaft 1, the support beam includes a crossbeam plate 2 and an H-shaped connecting seat arranged at both ends of the crossbeam plate 2, and the front thrust rod 5, the rear thrust rod 6, the support 1-1 and the H-shaped connecting seat located on the same side of the heavy truck are connected by connecting bolts 7 and fixing nuts 8.

[0023] In this embodiment, a support crossbeam is installed under the two supports 1-1 of the balancing shaft 1, and the front thrust rod 5 and the rear thrust rod 6 located on the same side of the heavy truck are installed at the same end of the support crossbeam. Under the connecting action of the support crossbeam, the frame crossbeam, the vehicle beam and the balancing shafts 1 on both sides form a stable supporting structure together. During the heavy-load operation of the vehicle, the problem of the split balancing shaft 1 causing the vehicle beam to crack can be solved, and the wear of the two supports 1-1 of the balancing shaft 1 can be reduced.

[0024] In this embodiment, the bracket crossbeam includes a crossbeam plate 2 and two H-shaped connecting seats, and the two H-shaped connecting seats are symmetrically arranged at both ends of the crossbeam plate 2. During actual installation, the front thrust rod 5, the rear thrust rod 6, the support 1-1 and the H-shaped connecting seat located on the same side of the heavy truck are connected by connecting bolts 7 and fixing nuts 8. The H-shaped connecting seat can play a stable and reliable connection role and will not cause any hindrance to the movement of the balance shaft 1, the front thrust rod 5 and the rear thrust rod 6. The installation method is simple and reliable.

[0025] like Figure 3 and Figure 4 As shown, in this embodiment, the H-shaped connecting seat includes an H-shaped support plate 3-1 connected to the crossbeam plate 2, a first vertical plate 3-2 and a second vertical plate 3-3 vertically arranged on the top surface of the H-shaped support plate 3-1, the number of the first vertical plates 3-2 is four, the number of the second vertical plates 3-3 is two, the four first vertical plates 3-2 and the two second vertical plates 3-3 are jointly arranged around the H-shaped support plate 3-1, and the first vertical plates 3-2 are each provided with a mounting hole 4 for the connecting bolts 7 to pass through.

[0026] In this embodiment, the two rectangular notches of the H-shaped support plate 3 - 1 can provide sufficient installation space for the front thrust rod 5 and the rear thrust rod 6 .

[0027] In this embodiment, the cross beam plate 2 and the two H-shaped support plates 3 - 1 are an integrally formed structure.

When the vertical distance between the axis of the mounting hole 4 and the top surface of the H-shaped support plate 3-1 is in the range of 24 mm to 30 mm, the installation height of the beam plate 2 and the two H-shaped support plates 3-1 can be ensured, and the installation height of the beam plate 2 and the two H-shaped support plates 3-1 can be avoided from being too low, resulting in friction with the ground.

[0030] In this embodiment, the height of the first vertical plate 3-2 and the height of the second vertical plate 3-3 are both 50 mm. The first vertical plate 3-2 and the second vertical plate 3-3 cannot contact the support 1-1 of the balance shaft 1, so as to avoid friction damage to the balance shaft 1 caused by the first vertical plate 3-2 and the second vertical plate 3-3.
