Technical Field

[0001] This utility model relates to the technical field of steering components for agricultural vehicles, specifically an enhanced power output steering gear set. Background Technology

[0002] The steering gear (also known as the steering system) in agricultural vehicles is a mechanical device used to control the direction of the vehicle. The steering gear transmits the driver's steering action to the front wheels to realize the steering function of the vehicle. The steering gear set is an important part of the steering system. It is mainly responsible for converting the driver's steering input into the vehicle's steering operation. It is usually composed of multiple gears and shafts, and the direction is changed by the rotation of the gears.

[0004] In the aforementioned patent, when lubricating oil is actually added to the steering gear set, the lubricating oil is usually poured directly into the device through the oil injection pipe. However, the lubricating oil will accumulate a small amount of solid sediment over a long period of time. Therefore, directly adding such lubricating oil into the device will not only fail to accelerate lubrication, but the solid impurities inside will also adhere to the outside of the gear set, affecting the normal meshing and transmission of the gear set. However, the aforementioned patent has not made any improvements to address this problem, nor has it made any innovative designs based on the original steering gear set. Utility Model Content

[0005] The purpose of this utility model is to provide an enhanced power output steering gear set to solve the problem mentioned in the background art that, in the current market, when lubricating oil is added to the steering gear set, the lubricating oil is usually poured directly into the device through the oil filling pipe. However, the lubricating oil will have a small amount of solid sediment after being left for a long time. Therefore, the lubricating oil directly added to the device will not only fail to accelerate the lubrication effect in the long term, but the solid impurities inside will also adhere to the outside of the gear set and affect the normal meshing and transmission of the gear set.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an enhanced power output steering gear set, comprising a lower mold shell body and an upper mold shell body, wherein the lower mold shell body is installed below the upper mold shell body, an output transmission mechanism is installed in the covered cavity of the lower mold shell body and the upper mold shell body, an injection processing mechanism is provided above the upper mold shell body, and an auxiliary cleaning mechanism is provided on the side of the lower mold shell body.

[0007] Preferably, the output transmission mechanism includes an output shaft, a drive gear, a driven gear, a support shaft, a drive bevel gear, a driven bevel gear, and a transmission shaft. The output shaft is rotatably mounted inside the housing of the lower mold housing body. A drive gear is fixedly mounted at the end of the output shaft located inside the lower mold housing body. A driven gear is meshed with the side of the drive gear. The driven gear is fixedly mounted through the outside of the support shaft. One end of the support shaft is rotatably mounted to the inner side wall of the lower mold housing body. A drive bevel gear is fixedly mounted at the other end of the support shaft. A driven bevel gear is meshed with the side of the drive bevel gear. The driven bevel gear is fixedly mounted through the outside of the transmission shaft, and the transmission shaft is rotatably mounted inside the housing of the lower mold housing body.

[0008] Preferably, the diameter of the drive gear is smaller than the diameter of the driven gear.

[0009] Preferably, the filling and processing mechanism includes an oil injection pipe, a one-way inlet valve, a filter pipe, a threaded mounting ring, a positioning support ring, and a filter screen. The oil injection pipe is conductively installed on the top outer wall of the upper mold shell body. The one-way inlet valve is installed on the outside of the oil injection pipe. The filter pipe is fitted to the top of the oil injection pipe. The threaded mounting ring is fixedly installed on the bottom outer wall of the filter pipe. The top outer wall of the oil injection pipe has a corresponding annular threaded groove for the threaded mounting ring to rotate and install. The positioning support ring is fixedly installed on the inner side wall of the filter pipe. The filter screen is fitted to the top outer wall of the positioning support ring.

[0010] Preferably, the filter screen is composed of a side ring and a funnel-shaped filter screen inside it, and the bottom outer wall of the filter screen located at the side ring is fixedly installed with abutment posts at equal intervals.

[0012] Preferably, heat dissipation fins are fixedly installed on the top outer wall of the lower mold shell body in an evenly spaced manner.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this enhanced power output steering gear set,

[0014] 1. When using this enhanced power output steering gear set, the design of the funnel-shaped filter assembly inside the oil filling pipe allows for the filtration of small amounts of solid impurities in the lubricating oil during the lubrication process. This ensures that the lubricating oil entering the device is free of solid sediment, guaranteeing its normal lubrication effect on the gears and preventing impurities from adhering to the gear assembly and affecting its normal transmission. Furthermore, the filter assembly is designed to be detachable, facilitating subsequent cleaning procedures. At the same time, the square drain pipe flush with the bottom of the device allows for one-time drainage when changing the lubricating oil, minimizing liquid residue. The overall structure is ingeniously designed and has excellent practical effect.

[0015] 2. When in use, this enhanced power output steering gear set incorporates two sets of gears of different sizes for transmission, with the smaller gear driving the larger gear. This design increases the output torque of the device, making the overall transmission more stable. Additionally, the design incorporates heat dissipation fins at the top of the device's outer casing, increasing the heat dissipation area and allowing the accumulated heat inside the device to dissipate to the outside more quickly. The overall structure is simple in design and has good practical effect. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 7 This utility model provides a technical solution: an enhanced power output steering gear set, including a lower mold shell body 1 and an upper mold shell body 2. The lower mold shell body 1 is installed below the upper mold shell body 2. An output transmission mechanism 3 is installed in the covered cavity of the lower mold shell body 1 and the upper mold shell body 2. An injection processing mechanism 4 is provided above the upper mold shell body 2. An auxiliary cleaning mechanism 5 is provided on the side of the lower mold shell body 1.

[0026] The output transmission mechanism 3 includes an output shaft 31, a drive gear 32, a driven gear 33, a support shaft 34, a drive bevel gear 35, a driven bevel gear 36, and a transmission shaft 37. The output shaft 31 is rotatably mounted inside the housing of the lower mold housing body 1. The drive gear 32 is fixedly mounted at the end of the output shaft 31 inside the lower mold housing body 1. The driven gear 33 is meshed with the side of the drive gear 32. The driven gear 33 is fixedly mounted through and outside the support shaft 34. One end of the support shaft 34 is rotatably mounted to the inner side wall of the lower mold housing body 1, and the other end of the support shaft 34 is fixedly mounted with a drive bevel gear. The drive bevel gear 35 is fitted with a driven bevel gear 36 on its side. The driven bevel gear 36 is fixedly mounted on the outside of the transmission shaft 37, and the transmission shaft 37 is rotatably mounted inside the housing of the lower mold body 1. The diameter of the drive gear 32 is smaller than the diameter of the driven gear 33. Here, the drive gear 32 and the driven gear 33 are set to different diameters so that the drive gear 32 rotates several times before driving the driven gear 33 to rotate once. This design of driving a large gear with a small gear increases the output torque of the device, making the whole device more stable during transmission.

[0027] The filling and processing mechanism 4 includes an oil injection pipe 41, a one-way inlet valve 42, a filter pipe 43, a threaded mounting ring 44, a positioning support ring 45, and a filter screen 46. The oil injection pipe 41 is installed on the outer top wall of the upper mold shell body 2. The one-way inlet valve 42 is installed outside the oil injection pipe 41. The filter pipe 43 is fitted onto the top of the oil injection pipe 41. A threaded mounting ring 44 is fixedly installed on the outer bottom wall of the filter pipe 43. A corresponding annular threaded groove is provided on the outer top wall of the oil injection pipe 41 for the threaded mounting ring 44 to rotate. A positioning support ring 45 is fixedly installed on the inner side wall of the filter pipe 43. A filter screen 46 is fitted onto the outer top wall of the positioning support ring 45. The filter screen 46 is composed of a side ring and a funnel-shaped filter screen inside it. The filter screen 46 is fixedly installed in a circumferential manner around the bottom outer wall of the side ring at equal intervals. The outer top wall of the positioning support ring 45 and the contact pin 47 are respectively provided with a cylindrical slot for the contact pin 47 to be inserted and installed. The filter screen inside the filter screen 46 is set in a funnel shape. By increasing the contact area between the filter screen 46 and the lubricating oil, the filter screen 46 can filter the lubricating oil more quickly. The threaded mounting ring 44 and the annular threaded groove make the filter tube 43 a detachable design, which facilitates the subsequent cleaning process of the filter screen 46. At the same time, the contact pin 47 and the contact slot are set to position the filter screen 46. When the filter screen 46 needs to be removed for cleaning, the filter tube 43 needs to be rotated until the threaded mounting ring 44 at its bottom end is completely disengaged from the threaded mounting groove. Then, the filter tube 43 can be pushed out from bottom to top. The subsequent installation is the same.

[0028] The auxiliary cleaning and draining mechanism 5 includes a square drain pipe 51 and a sealing cap 52. The square drain pipe 51 is installed on the outer side wall of the lower mold shell body 1 at the bottom position. The square drain pipe 51 and the sealing cap 52 are locked together by a bolt assembly. Heat dissipation fins are fixedly installed on the outer top wall of the lower mold shell body 1 at equal intervals. The square drain pipe 51 is set at the bottom of the lower mold shell body 1 so that the lower mold shell body 1 can discharge the lubricating oil inside at one time during the subsequent draining process, and there is less likely to be any residue.

[0029] Working principle: According to Figures 1 to 7 When the output shaft 31 rotates, it automatically drives the drive gear 32 to rotate, which in turn drives the driven gear 33 to rotate. Subsequently, the rotation of the driven gear 33 automatically drives the support shaft 34 to rotate, which in turn drives the drive bevel gear 35 to rotate. When the drive bevel gear 35 rotates, it automatically drives the driven bevel gear 36 to rotate, which in turn drives the transmission shaft 37 to rotate. The specific installation of the output shaft 31 and transmission shaft 37 with the existing steering gear assembly can be performed using existing operational techniques without modification. These are conventional operational techniques and will not be described in detail here. Please refer to the accompanying manual. Figure 2As shown, both the output shaft 31 and the transmission shaft 37 are provided with limiting components on their exteriors. These limiting components stably position the output shaft 31 and the transmission shaft 37 inside the lower mold housing body 1, so there is no need to worry about the output shaft 31 and the transmission shaft 37 being unstable during installation.

[0030] When lubricating oil needs to be added to the device after the lower mold shell body 1 and the upper mold shell body 2 are properly closed, the lubricating oil only needs to be poured into the filter tube 43. When the lubricating oil passes through the filter screen 46, the small amount of solid impurities carried in the lubricating oil will be automatically filtered and isolated above the filter screen 46. Then the clean lubricating oil will be injected into the cavity of the upper mold shell body 2 and the lower mold shell body 1 through the oil injection pipe 41. The one-way liquid inlet valve 42 here makes the lubricating oil only enter the device and cannot be discharged through the oil injection pipe 41.

[0031] The heat dissipation fins here increase the heat dissipation area of ​​the device, allowing the heat accumulated inside the device to be discharged to the outside more quickly. Since the hot air flow has an upward trend, placing the heat dissipation fins above the upper mold shell body 2 can more effectively achieve the effect of auxiliary heat dissipation.

[0032] When it is necessary to change the lubricating oil in the device, firstly, the bolt assembly needs to be removed from the outside of the square drain pipe 51 and the sealing cover 52. Then, the sealing cover 52 will change from the locked state to the movable state. Next, pull the sealing cover 52 directly from the side of the square drain pipe 51 along the horizontal side. The lubricating oil in the device can then be drained to the outside of the device through the square drain pipe 51 in one go. The bolt assembly here is a combination of bolt thread mounting grooves. The bolts here use a cross bolt structure to facilitate one-handed operation. Refer to the instruction manual for details. Figure 7 As shown, the square drain pipe 51 has a threaded mounting groove through it, and the bottom outer wall and top inner wall of the sealing cover 52 have the same threaded mounting groove. During installation, the bolt only needs to be passed through the two sets of threaded mounting grooves on the same side in one go from bottom to top. The same applies to disassembly. It is a conventional locking technology component, so it has not been described in detail in the previous text.

[0033] Meanwhile, existing devices generally use a funnel-shaped discharge pipe at the bottom of the device to discharge the lubricating oil in the gearbox. Although this method is portable, deposits, dirt, and metal shavings in the gearbox tend to accumulate at the bottom of the lubricating oil. This device, by using a side discharge method, can reduce the accumulation of deposits. The flow direction of the lubricating oil can carry away these impurities, preventing them from accumulating at the bottom of the oil, thereby reducing the negative impact on the lubrication effect. At the same time, the side discharge method can usually reduce the resistance when the lubricating oil is discharged, reduce the requirements for the oil discharge pipe, and make the oil discharge process smoother. Compared with the bottom discharge method, the design of the oil discharge pipe can be simplified, thereby reducing the resistance of oil flow and improving the oil discharge efficiency. Furthermore, the side discharge design can be more flexible to adapt to different gearbox structures, especially in some working conditions with narrow installation space. The side discharge method can avoid the structural limitations of the bottom and provide more design freedom. In actual cleaning, a cleaning brush or cleaning scraper can be extended into the bottom of the device through the square drain pipe 51 to effectively remove the impurities accumulated at the bottom of the device.

[0034] According to GB / T 17494-1998 standard, the national standard model of drive gear 32 is 4M / 50 tooth spur gear, and the national standard model of driven gear 33 is 6M / 50 tooth spur gear. Meanwhile, according to GB / T 12012-1989 standard, the national standard model of drive bevel gear 35 and driven bevel gear 36 is 5M / 40-80 tooth helical bevel gear.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
