Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for self-unloading cargo trucks, specifically to a front-drive linkage translational unloading drive device. Background Technology

[0002] Freight trucks typically have a cargo box where goods are stored during loading. Existing freight trucks unload by simultaneously lifting the front of the cargo box using hydraulic cylinders, tilting the box and allowing the materials to slide out. This unloading method is prone to tipping over, leading to accidents. To improve the safety of unloading freight trucks, the applicant has developed a horizontal self-dumping truck that allows for rapid unloading of materials from the cargo box while it remains horizontal.

[0003] Currently, the dump truck bodies of horizontal sliding dump trucks are designed with three sections of shafts for unloading to ensure complete material discharge. During unloading, the middle shaft moves first, followed by the two side shafts. This results in a complex, large, and heavy drive structure. Furthermore, with adjustments to national standards for truck load capacity, the approved cargo capacity of trucks has been significantly reduced. Consequently, the heavy weight of the three-section unloading device located at the rear of the truck body poses a risk of the truck's cab becoming suspended in the air when climbing slopes. Therefore, a single-shaft drive mechanism design has emerged. Specifically, a drive motor is installed at the bottom of the carriage to directly drive the main shaft. Then, the sprocket fixed on the main shaft drives the meshing transmission chain to move the scraper and unload the material in the carriage. However, since a dedicated drive motor needs to be added at the bottom of the carriage to provide power for the horizontal unloading, it not only occupies the space at the bottom of the carriage, but also requires special pipelines to meet the operating needs of the drive motor. Later maintenance is very inconvenient and costly.

[0004] Furthermore, regarding the specific dimensions of the dump truck body, when the length of the dump truck body is designed to be large, the unloading length range is relatively long. If the unloading main shaft is located at the front of the truck body near the front of the truck to drive the sprocket and drive chain, the drive chain and sprocket will easily become unstable due to the long unloading length range, making it difficult to ensure that the unloading process is completed. Utility Model Content

[0005] The purpose of this utility model is to provide a front-drive linkage translational unloading drive device to solve the above problems. It is equipped with a front-drive mechanical linkage drive component. The mechanical linkage drive component is driven by the power output shaft of the car at the front of the car, which replaces the drive method of setting a drive motor as the power source. The translational unloading operation can be completed by relying solely on the existing power output shaft of the car at the front of the car. See the following description for details.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model provides a front-drive linkage translational unloading drive device, including an automobile power output shaft body disposed at the front of an automobile. The outer end of the automobile power output shaft body is combined and connected with a front-drive mechanical linkage drive assembly to provide power for translational unloading by driving the mechanical linkage drive assembly through the automobile power output shaft body.

[0008] The inner perimeter of the mechanical linkage drive assembly is provided with a translational unloading assembly, which is used to drive the translational unloading assembly to complete the unloading operation.

[0009] Preferably, the mechanical linkage drive assembly includes a gearbox body, a first steering gear, and a second steering gear. The gearbox body is transversely positioned behind the end of the vehicle's power output shaft body. The gearbox input shaft of the gearbox body has its axial direction aligned with the length direction of the vehicle body, and its end is coaxially fixed to the rear end of the vehicle's power output shaft body. Gearbox output shafts are located on both sides of the gearbox body, and the axial direction of the gearbox output shafts is aligned with the width direction of the vehicle body. There are two first steering gears and two second steering gears, located on both sides, respectively. The first and second steering gears on both sides are respectively positioned below the vehicle body. At the four corner positions, the first and second steering gears on the same side are rotatably connected by a drive shaft with an axis arranged along the length of the carriage. The first steering gears on both sides are rotatably connected to steering input shafts with an axis arranged along the width of the vehicle body at their respective positions. The outer ends of the steering input shafts are coaxially fixed to the gearbox output shafts on the corresponding sides. The second steering gears on both sides are rotatably connected to unloading main shafts at their respective positions. The unloading main shaft is equipped with several parallel translation unloading components, which are driven by the rotation of the unloading main shaft to complete the unloading operation.

[0010] Preferably, both the first steering gear and the second steering gear are spiral bevel gear steering boxes.

[0011] Preferably, multiple bearing seats are coaxially rotatably connected to the outer periphery of the drive shaft on both sides, and the bearing seats are fixed to the bottom of the carriage to provide rotational support for the drive shaft.

[0012] Preferably, each of the translational unloading components includes a drive sprocket, a driven spindle, and a transmission chain. The drive sprockets are fixed in pairs around the unloading spindle. The driven spindle is positioned between the unloading spindle and the gearbox body along the width of the carriage, and the driven spindle is close to the outside of the gearbox body. Both ends of the driven spindle are rotatably connected to bearing supports, and the bearing supports are fixed to the bottom of the carriage. The driven sprockets are fixed in pairs around the periphery of the driven spindle. The drive sprockets and driven sprockets at the front and rear positions are aligned along the length of the carriage. A full circumference of the transmission chain is meshed between the outer circumferences of the front and rear aligned drive sprockets and driven sprockets. The scrapers are fixedly connected between the links of the transmission chain on both sides.

[0013] Preferably, there are at least two translational unloading components arranged side by side in the width direction of the carriage.

[0014] The aforementioned front-drive linkage translational unloading drive device, in its actual installation, features a front-drive mechanical linkage drive assembly. This assembly is driven by the vehicle's power output shaft located at the front of the vehicle, replacing the traditional drive motor method. The unloading operation of the translational unloading assembly can be completed solely using the existing power output shaft at the front of the vehicle, eliminating the need for pipeline installation, facilitating future maintenance, and reducing design costs. Specifically, the mechanical linkage drive assembly is designed with… Equipped with a first steering gear and a second steering gear, the rotational motion of the gearbox output shaft can be transmitted to the unloading main shaft via the drive shaft connected between the first and second steering gears on the same side. The forward rotation of the unloading main shaft then drives the drive sprocket of the translational unloading assembly to rotate forward. This forward rotation of the drive sprocket engages with the drive chain, causing the scraper to move horizontally and complete the material unloading. The mechanical linkage drive assembly has a compact structure and a reliable and easily implemented drive method, which helps to reduce the space occupied at the bottom of the vehicle body. The space allows for easy expansion of the adjustable length of the unloading main shaft and the bottom width of the carriage, which is beneficial to improving the material carrying capacity of the carriage and lowering the center of gravity of the carriage, thereby enhancing the stability of the vehicle during driving. After the scraper of the translational unloading assembly is moved and unloaded by the forward rotation of the unloading main shaft, the reverse rotation of the unloading main shaft can drive the drive sprocket of the translational unloading assembly to rotate in the opposite direction. The reverse rotation of the drive sprocket can then engage with the transmission chain and drive the transmission chain and the scraper back to their initial state. The translational unloading assembly... The return mechanism is simple and easy to implement, which facilitates the timely and stable return of the translational unloading assembly to its initial state after unloading. Since the unloading main shaft is located at the rear of the carriage and the mechanical linkage drive assembly is located at the front of the carriage, the front-drive operation of the unloading main shaft can be achieved by synchronously driving the transmission shafts on both sides of the mechanical linkage drive assembly. In the unloading process, the stability and availability of the translational unloading process can be ensured by driving the translational unloading assembly from the front of the unloading main shaft, which is suitable for use when the carriage is long and has a long unloading length range.

[0015] The beneficial effects are as follows: 1. This utility model is equipped with a front-drive mechanical linkage drive component. The mechanical linkage drive component is driven by the power output shaft body of the car at the front of the car, which replaces the drive method of setting a drive motor as the power source. The drive and unloading operation of the translation unloading component can be completed by relying on the existing power output shaft body of the car at the front of the car. There is no need to lay pipelines and it is convenient for later maintenance. At the same time, it helps to reduce design costs.

[0016] 2. The mechanical linkage drive assembly is equipped with a first steering gear and a second steering gear. By connecting the transmission shaft between the first and second steering gears on the same side, the rotational motion of the gearbox output shaft can be transmitted to the unloading main shaft. Then, the forward rotation of the unloading main shaft can drive the drive sprocket of the translational unloading assembly to rotate in the forward direction. The forward rotation of the drive sprocket can make the transmission chain mesh with it and rotate, so that the scraper can move horizontally to complete the material unloading. The mechanical linkage drive assembly has a compact structure and a reliable and easy-to-implement drive method. It is beneficial to reduce the space occupied at the bottom of the car body, so as to facilitate the widening of the adjustable length of the unloading main shaft and the bottom width of the car body, which is beneficial to improve the material carrying capacity of the car body. At the same time, it can lower the center of gravity of the car body and enhance the stability of the vehicle during driving.

[0017] 3. After the scraper of the translational unloading assembly is moved and unloaded by the forward rotation of the unloading spindle, the reverse rotation of the unloading spindle can drive the drive sprocket of the translational unloading assembly to rotate in the opposite direction. Thus, the reverse rotation of the drive sprocket can make the transmission chain mesh with it and drive the transmission chain and scraper back to the initial state. The return method of the translational unloading assembly is simple and easy to implement, so that the translational unloading assembly can return to the initial state in a timely and stable manner after unloading is completed.

[0018] 4. The unloading main shaft is located at the rear of the carriage, while the mechanical linkage drive assembly is located at the front of the carriage. The front-drive operation of the unloading main shaft can be achieved by synchronously driving the transmission shafts on both sides of the mechanical linkage drive assembly. Then, during the unloading process, the unloading main shaft drives the unloading assembly to ensure the stability and availability of the unloading process, which is suitable for use when the carriage is long and has a long unloading length range.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] See Figure 1As shown, this utility model provides a front-wheel drive linkage translational unloading drive device, including a vehicle power output shaft body 1 located at the front of the vehicle. The outer end of the vehicle power output shaft body 1 is connected to a front-wheel drive mechanical linkage drive assembly 2 to provide power for translational unloading by driving the mechanical linkage drive assembly 2 through the vehicle power output shaft body 1. Specifically, the mechanical linkage drive assembly 2 includes a gearbox body 202, a first steering gear 205, and a second steering gear 209. The gearbox body 202 is transversely positioned behind the end of the vehicle power output shaft body 1. The gearbox input shaft 201 of the gearbox body 202 is axially aligned with the length direction of the vehicle body and its end is connected to the rear of the vehicle power output shaft body 1. The transmission body 202 is coaxially fixed at both ends. A transmission output shaft 203 is provided on both sides of the transmission body 202, and the axis of the transmission output shaft 203 is aligned with the width direction of the vehicle body. There are two first steering gears 205 and two second steering gears 209, located on both sides. The first steering gears 205 and 209 on both sides are respectively located at the four corners below the vehicle body. A drive shaft 207 with its axis along the length of the vehicle body is rotatably connected between the first steering gears 205 and 209 on the same side. A steering input shaft 204 with its axis along the width direction of the vehicle body is rotatably connected to the first steering gears 205 on both sides at positions opposite to each other. The outer ends of the input shaft 204 are coaxially fixed to the corresponding side of the gearbox output shaft 206. The second steering gears 209 on both sides are rotatably connected to the unloading main shaft 208, which is equipped with several parallel-arranged translational unloading components 3. These components are driven by the rotation of the unloading main shaft 208 to complete the unloading operation. This design allows the unloading operation of the translational unloading components 3 to be driven solely by the existing power output shaft 1 at the front of the vehicle, eliminating the need for pipeline installation and facilitating future maintenance. Furthermore, the forward rotation of the unloading main shaft 208 drives the drive sprocket 3 of the translational unloading components 3. The forward rotation of the drive sprocket 306 enables the transmission chain 305 to mesh and rotate, thereby causing the scraper 304 to move horizontally and complete the material unloading. The mechanical linkage drive assembly 2 has a compact structure and a reliable and easy-to-implement drive method. After the scraper 304 of the translational unloading assembly 3 is moved and unloaded, the reverse rotation of the drive sprocket 306 of the translational unloading assembly 3 can drive it to rotate in the opposite direction. This reverse rotation of the drive sprocket 306 enables the transmission chain 305 to mesh and drive the transmission chain 305 and scraper 304 back to their initial positions. The return method of the translational unloading assembly 3 is simple and easy to implement.

[0025] See Figure 1As shown, a translational unloading assembly 3 is provided within the inner perimeter of the mechanical linkage drive assembly 2. This assembly is driven by the mechanical linkage drive assembly 2 to complete the unloading operation. Specifically, each translational unloading assembly 3 includes a drive sprocket 306, a driven main shaft, and a transmission chain 305. The drive sprockets 306 are fixed in pairs around the unloading main shaft 208. A driven main shaft is positioned between the unloading main shaft 208 and the gearbox body 202 along the width direction of the cargo box, and is located close to the outside of the gearbox body 202. Bearing supports 301 are rotatably connected to both ends of the driven main shaft, and these supports 301 are fixed to the bottom of the cargo box. Driven sprockets 303 are fixed in pairs around the driven main shaft, with their positions relative to each other. The driving sprocket 306 and driven sprocket 303 are aligned along the length of the carriage. A full-circumference transmission chain 305 is meshed between the outer circumferences of the driving sprocket 306 and driven sprocket 303, and scrapers 304 are fixedly connected between the links of the adjacent transmission chains 305 on both sides. The purpose of this arrangement is that the driving sprocket 306 can drive the meshing transmission chain 305 to rotate in the forward and reverse direction with the unloading main shaft 208. Then, the forward rotation of the transmission chain 305 can drive the scraper 304 to move forward, and the moving scraper 304 can move the material in the carriage horizontally and unload it. At the same time, the reverse rotation of the transmission chain 305 can drive the scraper 304 to move backward and return to the initial position.

[0026] See Figure 1As shown, the mechanical linkage drive assembly 2 and the translational unloading assembly 3 have been optimized as follows. Specifically, for the mechanical linkage drive assembly 2, both the first steering gear 205 and the second steering gear 209 are spiral bevel gear steering boxes. Preferably, the gearbox body 202 is equipped with a clutch function. This configuration ensures that the gearbox body 202 has the required operability during actual use, and facilitates the rotation of the unloading main shaft 208 via the drive shaft 207 through the first steering gear 205 and the second steering gear 209. Optionally, multiple bearing seats 206 are coaxially rotatably connected to the outer periphery of the drive shaft 207 on both sides, and the bearing seats 206 are fixed to the bottom of the carriage to provide rotational support for the drive shaft 207. This provides stable rotational support for the drive shaft 207 by using multiple bearing seats 206, preventing instability due to excessive span. Specifically, regarding the translation unloading assembly 3, there are at least two translation unloading assemblies 3 arranged side by side in the width direction of the carriage. This allows for convenient maintenance and replacement through the independent scraper 304 of each translation unloading assembly 3. It also prevents the scraper 304 from being bent and damaged by the material due to its excessive span when installed at the bottom of the widened carriage. Optionally, the transmission ratio between the drive sprocket 306 and the driven sprocket 303 is 1, so that the transmission chain 305 has good and reliable transmission stability during the meshing operation between the outer periphery of the drive sprocket 306 and the driven sprocket 303, ensuring that the translation unloading process can be completed smoothly.

[0027] With the above structure, in practical application, the presence of a front-drive mechanical linkage drive assembly 2, which is driven by the vehicle's power output shaft 1 located at the front of the vehicle, replaces the traditional drive method using a drive motor as the power source. This allows the translational unloading assembly 3 to be driven and unloaded solely by the existing power output shaft 1 at the front of the vehicle, eliminating the need for pipeline installation, facilitating future maintenance, and reducing design costs. Specifically, the mechanical linkage drive assembly 2 includes a first steering gear 205 and a second steering gear 209. In this way, the rotational motion of the gearbox output shaft 203 can be transmitted to the unloading main shaft 208 by connecting the drive shaft 207 between the first steering gear 205 and the second steering gear 209 on the same side. Then, the forward rotation of the unloading main shaft 208 can drive the drive sprocket 306 of the translational unloading assembly 3 to rotate in the forward direction. Thus, the forward rotation of the drive sprocket 306 can cause the drive chain 305 to mesh and rotate with it, thereby causing the scraper 304 to move in the translational direction to complete the material unloading. The mechanical linkage drive assembly 2 has a compact structure and a reliable and easy-to-implement drive method, which helps to reduce the space occupied at the bottom of the carriage, thereby facilitating the unloading of materials. The increased length of the unloading spindle 208 and the width of the bottom of the truck bed improve the material carrying capacity of the truck bed and lower the center of gravity, thus enhancing the stability of the vehicle during operation. After the scraper 304 of the translational unloading assembly 3 is moved and unloaded by the forward rotation of the unloading spindle 208, the reverse rotation of the unloading spindle 208 drives the drive sprocket 306 of the translational unloading assembly 3 to rotate in the opposite direction. This reverse rotation of the drive sprocket 306 allows the transmission chain 305 to mesh with it, returning the transmission chain 305 and the scraper 304 to their initial positions. The return method is simple and easy to implement, which makes it easy for the translational unloading assembly 3 to return to its initial state in a timely and stable manner after unloading. Since the unloading main shaft 208 is located at the rear of the carriage and the mechanical linkage drive assembly 2 is located at the front of the carriage, the transmission shafts 207 on both sides of the mechanical linkage drive assembly 2 can synchronously drive the unloading main shaft 208. Then, during the unloading process, the unloading main shaft 208 drives the translational unloading assembly 2 in the front to ensure the stability and availability of the translational unloading process, which is suitable for the use needs when the carriage is long and has a long unloading length range.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
