Description

Technical Field

[0001] This application relates to the field of engineering vehicle steering assembly technology, and more particularly to an engineering vehicle steering assembly and a material loading vehicle. Background Technology

[0002] The material handling truck is designed with a large hopper almost as long as the vehicle body. When the hopper is full, the increased weight inevitably shifts the vehicle's center of gravity forward. To address this shift, engineers had to sacrifice some space at the front of the vehicle, repositioning the hydraulic cylinders connecting the body and the hopper rearward to balance the vehicle's center of gravity. However, this adjustment introduced a new challenge: the rearward movement of the hydraulic cylinders encroached on the space originally occupied by the front wheels. To solve this problem, a compact steering assembly was needed to ensure that the vehicle could still be nimbly steered while maintaining balance. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems by providing an engineering vehicle steering assembly and a material loading vehicle.

[0004] The technical solution of this application is implemented as follows:

[0005] In a first aspect, this application provides a steering assembly for an engineering vehicle, the steering assembly comprising:

[0006] A frame connecting frame is fixedly installed on the bottom of the frame of the engineering vehicle;

[0007] A drive wheel connecting bracket is rotatably mounted on the bottom of the frame connecting bracket;

[0008] The frame connecting frame is equipped with a transition bearing;

[0009] The inner ring of the adapter bearing is fixedly connected to the frame connecting bracket, and the outer ring of the adapter bearing is connected to the top of the drive wheel connecting bracket.

[0010] The outer ring has helical toothed grooves on its outer circumferential surface;

[0011] A worm gear is also horizontally installed inside the frame connecting frame. The worm gear is rotatably installed inside the frame connecting frame. Helical teeth are installed on the outer circumferential surface of the worm gear. The helix angle of the helical tooth groove matches the helix angle of the helical tooth so that the helical tooth of the worm gear can be embedded in the helical tooth groove.

[0012] The frame connecting bracket is also equipped with a drive component for driving the worm gear.

[0013] The advantages or beneficial effects of the above technical solutions include at least the following:

[0014] Secondly, this application also provides a feeding vehicle, which is equipped with an engineering vehicle steering assembly as described above, and the frame connecting frame of the engineering vehicle steering assembly is mounted on the rear of the feeding vehicle via a first bolt assembly.

[0015] The advantages or beneficial effects of the above technical solutions include at least the following:

[0016] A rotatable transition bearing, installed within the internal structure of the frame connecting bracket, enables smooth rotation between the drive wheel connecting bracket and the frame connecting bracket. Furthermore, by moving the hydraulic cylinder connecting the feeding vehicle and the hopper rearward, the vehicle's center of gravity can be adjusted to a more balanced central position. This design not only helps prevent the vehicle from tilting forward during operation but also, by mounting the feeding vehicle's engine inside the drive wheel connecting bracket, further ensures that the wheels are directly driven by the engine, thereby improving the overall system's operational efficiency and stability.

[0030] An engineering vehicle steering assembly, specifically, the steering assembly 10 includes:

[0031] A frame connecting frame 11 is fixedly installed at the bottom of the frame of the engineering vehicle; a drive wheel connecting frame 13 is rotatably installed at the bottom of the frame connecting frame 11. Specifically, the frame connecting frame 11 is fixedly connected to the engineering vehicle via a first bolt assembly 14, wherein the wheels of the engineering vehicle are installed below the drive wheel connecting frame 13; furthermore, a transition bearing 12 is installed inside the frame connecting frame 11; the inner ring 122 of the transition bearing 12 is also fixedly connected to the frame connecting frame 11 via the first bolt assembly 14, such as... Figure 2 As shown in the enlarged right section, the frame connecting bracket 11 has bolt holes that mate with the first bolt assembly 14, and the inner ring 122 also has bolt holes that mate with these bolt holes. During assembly, these two bolt holes correspond to and are interconnected. During installation, the first bolt assembly 14 passes through these two holes, thus fixing the inner ring 122, the frame connecting bracket 11, and the engineering vehicle together. The outer ring 121 of the transition bearing 12 is connected to the top of the drive wheel connecting bracket 13. Specifically, the outer ring 121 of the transition bearing 12 is fixedly connected to the drive wheel connecting bracket 13 via the second bolt assembly 15. The rotation of the inner ring 122 and the outer ring 121 of the transition bearing 12 enables wheel steering. Figure 5 The upper and lower halves are shown.

[0032] Based on the above structure, specifically, a helical tooth groove 1211 is formed on the outer peripheral surface of the outer ring 121; and a worm gear 111 is also horizontally installed inside the frame connecting bracket 11. The worm gear 111 is rotatably installed inside the frame connecting bracket 11, and a helical tooth 1111 is installed on the outer peripheral surface of the worm gear 111. The helix angle of the helical tooth groove 1211 matches the helix angle of the helical tooth 1111, so that the helical tooth 1111 of the worm gear 111 can be embedded in the helical tooth groove 1211. Through the rotation of the worm gear 111, the helical tooth 1111... 1. Rotate around the axis of worm 111, thereby rotating the outer ring 121 through the helical tooth groove 1211. Since the inner ring 122 is fixed to the frame connecting frame 11 and the outer ring 121 is fixed to the drive wheel connecting frame 13, the relative rotation of the frame connecting frame 11 and the drive wheel connecting frame 13 can be realized, thereby realizing the rotation of the steering assembly 10. In addition, an oil nozzle 112 is also installed on the outer shell of the frame connecting frame 11 at the position corresponding to the worm 111. The oil nozzle 112 is used to inject lubricating oil into the worm 111 to realize the maintenance of the equipment.

[0033] It should be noted that the lead angle of the worm 111 is smaller than the friction angle, and the lead angle is ≤20°. This enables the worm 111 and the outer ring 121 to self-lock, that is, the rotation of the outer ring 121 is restricted by the worm 111 and cannot rotate the worm 111, so as to prevent the wheel from rotating automatically.

[0034] Furthermore, the frame connecting frame 11 is also equipped with a drive component for driving the worm gear 111 to achieve the rotation of the worm gear 111. The drive component includes a servo motor 113. The housing of the servo motor 113 is installed on the outer wall of the frame connecting frame 11, and the rotating shaft extends into the frame connecting frame 11 and connects to the worm gear 111 to control the rotation of the worm gear 111. The servo motor 113 can also control the rotation speed to achieve precise control of the steering assembly 10.

[0035] An embodiment of this utility model also provides a feeding vehicle 20, which is equipped with the engineering vehicle steering assembly 10 as described above. The frame connecting frame 11 of the engineering vehicle steering assembly 10 is installed at the rear of the feeding vehicle 20 via a first bolt assembly 14, thereby realizing the steering of the feeding vehicle 20. In addition, the engine of the feeding vehicle 20 is installed in the drive wheel connecting frame 13, and the engine is used to drive the wheels to rotate, thereby realizing the movement of the feeding vehicle 20. Figure 6 As shown, the front wheels of the feeding vehicle 20 can be driven wheels, and the rear steering assembly 10 wheels can be driven wheels. Integrating steering and driving into one assembly facilitates equipment maintenance and also frees up more space in other parts of the vehicle. For example, the hydraulic cylinder connecting the feeding vehicle 20 to the hopper can be moved backward to balance the center of gravity of the vehicle to the middle, effectively preventing the vehicle from tilting forward.

[0036] In the description of this application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] Those skilled in the art should understand that the above embodiments are merely for illustrative purposes and are not intended to limit the scope of this application. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of this application.
