Description

Technical Field

[0001] This utility model relates to the field of sweeper vehicles, specifically to an adjustment structure for a drive axle and a drive axle assembly having the adjustment structure. Background Technology

[0002] A sweeper is a tool used for cleaning roads.

[0003] Currently, the drive structure of existing sweepers generally involves mounting the drive unit on the chassis, with a chain driving the rear wheel drum. However, the chain cannot be tensioned or adjusted.

[0004] When a chain becomes fatigued and loose after prolonged operation, it often comes off, which can cause inconvenience to the operator or affect safe operation.

[0005] Therefore, after using a sweeper for a period of time, people need to adjust its chain. For ordinary sweepers, the drive axle is welded to the frame by a bracket, and its height position cannot be adjusted, making disassembly and maintenance inconvenient.

[0006] For some sweepers, although the chain can be adjusted, the adjustment method is relatively complicated.

[0007] At the same time, for some drive structures with a large span and a certain angle between the two sprockets, adjusting the chain cannot achieve the desired effect.

[0008] The existing patent 201420361473.X - a sweeper with a centrally located dustbin - does not clearly disclose the technical content that solves the above-mentioned technical problems.

[0009] Therefore, in order to improve or solve at least one of the above problems, it is necessary to optimize the design of traditional drive axle or chain structure. Utility Model Content

[0010] The purpose of this invention is to provide an adjustment structure that allows for adjustment of chain tension by adjusting the drive axle.

[0016] The support base includes a longitudinal plate and a transverse plate. The transverse plate is connected to the base plate through the longitudinal plate. The transverse plate is set perpendicular to the longitudinal plate. The longitudinal adjusting bolt is connected to the transverse plate.

[0017] The nut assembly includes an upper nut and a lower nut, which are distributed on both sides of the transverse plate.

[0018] The adjustment mechanism further includes a locking component, which includes a support plate disposed on the base plate and a connecting plate disposed on the drive axle. The support plate and the connecting plate are connected by a connecting part.

[0019] The connecting part includes a connecting bolt, which is arranged to pass through both the connecting plate and the support plate.

[0020] The connecting part also includes a waist-shaped groove provided on the support plate; the connecting bolt passes through the waist-shaped groove on the support plate and connects to the connecting plate.

[0021] A drive axle assembly includes a drive axle, the two ends of which are connected to a chassis via the adjustment structure.

[0031] The adjustment structure disclosed in this utility model is mainly used to adjust the longitudinal height of the drive axle 5 from the chassis 1, and the ultimate purpose is to adjust the tension of the chain 2.

[0032] Specifically, the adjustment structure disclosed in this utility model mainly includes a base 3-1, which serves as a supporting foundation. The base 3-1 is arranged on the chassis 1 and is primarily used to elevate, support, and fix the drive axle 5. In this utility model, the base 3-1 is connected to the drive axle 5 via an adjustment mechanism 3. The adjustment mechanism 3 allows for adjustment of the longitudinal position of the drive axle 5, thereby changing the tension of the chain 2. Specifically, the adjustment mechanism 3 disclosed in this utility model includes a longitudinal adjustment component. The longitudinal adjustment component includes a longitudinal adjustment bolt 33 disposed on the drive axle 5, which is connected to the base 3-1. In actual use, the height of the drive axle 5 is adjusted by adjusting the relative insertion position of the longitudinal adjustment bolt 33 on the base 3-1.

[0033] Furthermore, in this utility model, the base 3-1 includes a base plate 31, which is a flat plate structure. The base plate 31 is a horizontally arranged plate structure, which increases the contact area between the base 3-1 and the chassis 1. At the same time, in this utility model, the base plate 31 is provided with a support seat 32, which is a connecting seat, facilitating the connection and arrangement of the longitudinal adjusting bolt 33 on the base 3-1. The longitudinal adjusting bolt 33 is connected to the support seat 32. The longitudinal adjusting bolt 33 is provided with a nut group for adjusting the relative position of the longitudinal adjusting bolt 33 and the support seat 32. By rotating the nut group, the insertion depth of the longitudinal adjusting bolt 33 on the support seat 32 is changed, thereby realizing the change of the longitudinal position of the longitudinal adjusting bolt 33, and ultimately driving the change of the longitudinal arrangement height of the drive axle 5.

[0034] Furthermore, in this invention, the support base 32 includes a longitudinal plate 322 and a transverse plate 321. The transverse plate 321 is connected to the base plate 31 via the longitudinal plate 322, and the transverse plate 321 is arranged perpendicular to the longitudinal plate 322. The longitudinal adjusting bolt 33 is connected to the transverse plate 321. This invention, through the cooperative use of the transverse plate 321 and the longitudinal plate 322, facilitates the arrangement and placement of the longitudinal adjusting bolt 33. Simultaneously, through the above design, the support base 32 is an inverted L-shaped plate structure. This arrangement facilitates subsequent rotation of the nut assembly, thereby changing the insertion depth of the longitudinal adjusting bolt 33 on the support base 32. The nut assembly includes an upper nut and a lower nut, which are distributed on both sides of the transverse plate 321.

[0035] Furthermore, the adjustment mechanism 3 in this utility model also includes a locking component, which includes a support plate 6 disposed on the base plate 31 and a connecting plate 4 disposed on the drive axle 5. The support plate 6 and the connecting plate 4 are connected by a connecting part. The locking component disclosed in this utility model can lock and fix the drive axle 5 after the position is adjusted, ensuring the stability of the position of the drive axle 5. In addition, in this utility model, the support plate 6 is set perpendicular to the base plate 31, and the transverse plate 321 in the support base 32 is required to fit against the side of the support plate 6. Based on this design, the integrity of the base 3-1 is ensured.

[0036] The connection part facilitates the locking and fixing of the support plate 6 and the connecting plate 4, thereby limiting the position of the drive axle 5.

[0037] Furthermore, in this utility model, the connecting part includes a connecting bolt 62, which is arranged to pass through both the connecting plate 4 and the support plate 6. In subsequent use, the connecting bolt 62 passes through both the connecting plate 4 and the support plate 6, which can effectively lock and fix the connecting plate 4 and the support plate 6. In actual arrangement, both sides of the connecting plate 4 and the support plate 6 are provided with connecting parts, which greatly ensures the stability of the connection between the connecting plate 4 and the support plate 6.

[0038] Meanwhile, the connecting part in this utility model also includes a waist-shaped groove 61 provided on the support plate 6; the connecting bolt 62 passes through the waist-shaped groove 61 on the support plate 6 and is connected to the connecting plate 4; the setting of the waist-shaped groove 61 allows the connecting bolt 62 to have longitudinal movement capability along the support plate 6, avoiding interference between the drive axle 5 and the support plate 6 when it is raised or lowered.

[0039] A drive axle 5 assembly includes a drive axle 5, the two ends of which are connected to the chassis 1 via the adjustment structure. Based on the above design, this utility model not only facilitates the arrangement of the drive axle 5 on the chassis 1, but also simplifies subsequent adjustment operations.

[0040] Obviously, the specific implementation of this utility model is not limited to the above-mentioned methods. Any non-substantial improvements made using the inventive concept and technical solution of this utility model are within the protection scope of this utility model.
