Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a steering gear oil tank assembly for commercial vehicles. Background Technology

[0002] To further optimize steering performance, most vehicles are equipped with power steering systems. The power steering system's mechanical structure is driven by hydraulic pressure from the power steering pump. A power steering system typically consists of three core components: the steering gear assembly, the steering gear pump assembly, and the steering gear reservoir assembly. The steering gear reservoir assembly is located in the power steering fluid flow path and is fixed to the vehicle frame or other structures by brackets. The steering gear reservoir assembly is one of the important components of a vehicle's HPS (Hydraulic Steering System) and has the following functions: adding hydraulic fluid to the power steering system; checking the hydraulic fluid level; providing space for the thermal expansion of the hydraulic fluid; providing compensating hydraulic fluid when the reservoir expands; removing air from the power steering system; and filtering impurities from the hydraulic fluid.

[0003] In existing technologies, some vehicles with steering systems use steering gear oil tank assemblies that consist of an oil tank bracket, an oil tank, an oil tank bracket limiting sleeve, hexagonal flange bolts, and nuts. The dimensional alignment of the oil tank bracket and the oil tank is difficult to guarantee, requiring the oil tank bracket to be aligned before proper assembly during reassembly. This results in high reassembly efficiency and cost. Furthermore, the steering gear oil tank assembly cannot be assembled using readily available tools during final vehicle assembly, leading to low assembly efficiency. Therefore, there is a need for a steering gear oil tank assembly that offers high assembly efficiency and strong adaptability. Utility Model Content

[0004] The present invention aims to provide a steering gear oil tank assembly for commercial vehicles, which provides a steering gear oil tank assembly with high assembly efficiency and strong adaptability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a commercial vehicle steering gear oil tank assembly, including an oil tank and a bracket plate, the bracket plate including a snap-fit ​​part, the snap-fit ​​part including two symmetrically arranged snap-fit ​​plates, the side wall of the oil tank is provided with a dovetail block, the dovetail block can slide into the two snap-fit ​​plates for snap-fit ​​fixation, the top of the dovetail block is also provided with a limiting plate, when the dovetail block slides to a set position, the snap-fit ​​plates abut against the limiting plate.

[0006] The beneficial effects of this plan are:

[0007] During use, the dovetail block is slidably inserted between the two clamping plates for locking and limiting. After the dovetail block slides to its limit position, the limiting plate at the top of the dovetail block abuts against the clamping plate, preventing the steering gear oil tank from sliding down and thus achieving locking and fixing of the oil tank. With the above settings, as long as the oil tank is equipped with a dovetail block, oil tanks of different sizes can be installed and fixed onto the bracket plate. The assembly process is simple; just insert the dovetail block between the clamping plates. The assembly efficiency is high. The combination of the sliding insertion of the dovetail block and the limiting of the clamping plate forms a reliable fixing structure that can maintain good stability even during long-term use. When the dovetail block slides to the set position, the limiting plate will automatically abut against the clamping plate to prevent the oil tank from sliding down. No additional adjustment or tightening operations are required, further simplifying the assembly steps.

[0008] Preferably, as an improvement, the dovetail block is a conical dovetail block, and the distance between the tops of the two plates is greater than the distance between the bottoms of the two plates.

[0009] The beneficial effects are as follows: by setting a conical dovetail block, when the dovetail block is slidably inserted, the conical dovetail block self-locks through a tight fit with the clamping plate. In addition to limiting the limit block, the clamping plate can also provide support for the dovetail block and the oil tank, avoiding the use of the limit plate to bear the weight of the oil tank alone, further supporting and preventing the oil tank from falling off, and improving the safety of the oil tank fixing.

[0010] Preferably, as an improvement, the dovetail block has a slot and also includes a support plate, which is inclinedly disposed between the two clamping plates, and the bottom end of the support plate can abut against the bottom surface of the slot.

[0011] The beneficial effects are as follows: after the oil tank is assembled with the above settings, the downward sliding dovetail block will be locked in place by the clamping plate, and the bottom surface of the upward sliding dovetail groove will abut against the bottom surface of the support plate to prevent it from falling off, thus further ensuring the stability of its installation.

[0012] Preferably, as an improvement, both sides of the snap-fit ​​portion are provided with connecting portions, and the ends of the connecting portions are provided with threaded holes.

[0013] The beneficial effect is that it makes it easy to install the bracket plate onto the frame with bolts, making the installation convenient, quick, and stable.

[0014] Preferably, as an improvement, the taper of the conical dovetail block is 8.5 degrees.

[0015] Preferably, as an improvement, the oil tank includes an oil tank body, an oil tank cover fitted onto the oil tank body, and a dust cover covering the oil tank cover. The oil tank body is also connected to an oil tank inlet and an oil tank outlet.

[0016] The beneficial effects are as follows: the oil tank cover is used to seal the oil tank body to prevent oil leakage; the dust cover is placed on the oil tank cover to provide further external protection and prevent dust, dirt and impurities from entering the oil tank. The dual protection design effectively enhances the sealing performance of the oil tank system, ensures the purity of the hydraulic oil, and avoids the normal operation of the power steering system due to the entry of external contaminants.

[0017] Preferably, as an improvement, the support plate is made of plastic with a thickness of 4-6mm.

[0018] The beneficial effect is that it gives it a certain thickness to ensure its support capacity. Attached Figure Description

[0025] Example

[0026] The implementation examples are basically as follows Figures 1-4 As shown, Figure 1 and Figure 2 The illustrated commercial vehicle steering gear oil tank assembly includes an oil tank and a bracket plate. The bracket plate includes a snap-fit ​​portion, which comprises two symmetrically arranged snap-fit ​​plates 1. A dovetail block 2 is provided on the side wall of the oil tank. The dovetail block 2 can slide between the two snap-fit ​​plates 1 for snap-fit ​​fixation. A limiting plate 3 is also symmetrically provided on the top of the dovetail block 2. Figure 4 As shown, when the dovetail block 2 slides to the set position, the locking plate 1 abuts against the limiting plate 3. The dovetail block 2 is slidably inserted between the two locking plates 1 for locking and limiting. After the dovetail block 2 slides to the limit position, the limiting plate 3 at the top of the dovetail block 2 abuts against the locking plate 1 to prevent the steering gear oil tank from sliding down, thus achieving locking and fixing of the oil tank; Figure 3As shown, the dovetail block 2 is a conical dovetail block 2. In this embodiment, the taper of the conical dovetail block 2 is 8.5 degrees, and the distance between the tops of the two clamping plates 1 is greater than the distance between the bottoms of the two clamping plates 1. By setting the conical dovetail block 2, when the dovetail block 2 is slidably inserted, the two clamping plates 1 not only limit the positioning block but also provide support for the dovetail block 2 and the oil tank, avoiding the use of only the positioning plate 3 to bear the weight of the oil tank, further supporting and preventing the oil tank from falling off, and improving the safety of the oil tank fixing. The support plate in this embodiment is made of plastic with a thickness of 4-6mm.

[0027] like Figure 3 As shown, the dovetail block 2 in this embodiment also has a slot 5, and includes, for example, Figure 2 The support plate 4 shown is inclined between the two clamping plates 1. When the dovetail block 2 is inserted into the bottom of the clamping plate 1, the bottom end of the support plate 4 can abut against the bottom surface of the slot 5. After assembly with the above settings, the dovetail block 2 will be clamped by the clamping plate 1 when the oil tank slides down, and the bottom surface of the dovetail slot and the bottom surface of the support plate 4 will abut against each other when the oil tank slides up, so as not to fall off, further ensuring the stability of its installation. Both sides of the clamping part are provided with connecting parts 6, and the ends of the connecting parts 6 are provided with threaded holes 7, which makes it easy to install the bracket plate onto the frame with bolts. The installation is convenient, quick and stable.

[0028] The oil tank includes an oil tank body 8, an oil tank cover 9 covering the oil tank body 8, and a dust cover 10 covering the oil tank cover 9. The oil tank body 8 is also connected to an oil tank inlet 11 and an oil tank outlet 12. The oil tank cover 9 is used to seal the oil tank body 8 to prevent oil leakage. The dust cover 10 covers the oil tank cover 9 to further provide external protection and prevent dust, dirt and impurities from entering the oil tank. The dual protection effectively enhances the sealing performance of the oil tank system, ensures the purity of the hydraulic oil, and avoids the normal operation of the power steering system due to the entry of external contaminants.

[0029] The specific implementation process is as follows:

[0030] In use, the dovetail block 2 is slidably inserted between the two clamping plates 1 for locking and limiting. After the dovetail block 2 slides to its limit position, the limiting plate 3 at the top of the dovetail block 2 abuts against the clamping plate 1 to prevent the steering gear oil tank from sliding down, thus achieving locking and fixing of the oil tank. With the above settings, as long as the dovetail block 2 is set on the oil tank, oil tanks of different specifications can be installed on the bracket plate for fixing. The assembly process is simple; just insert the dovetail block 2 between the clamping plates 1. The assembly efficiency is high. The sliding insertion of the dovetail block 2 and the limiting of the clamping plate 1 combine to form a reliable fixing structure that can maintain good stability even during long-term use. When the dovetail block 2 slides to the set position, the limiting plate 3 will automatically abut against the clamping plate 1 to prevent the oil tank from sliding down. No additional adjustment or tightening operation is required, further simplifying the assembly steps. When the dovetail block 2 is inserted into the bottom of the clamping plate 1, the bottom end of the support plate 4 can abut against the bottom surface of the slot 5. After assembly with the above settings, the dovetail block 2 will be clamped by the clamping plate 1 when the oil tank slides down, and the bottom surface of the dovetail groove and the bottom surface of the support plate 4 will abut against the oil tank when it slides up, so that it will not fall off, further ensuring the stability of its installation.
