Description

Technical Field

[0001] This utility model belongs to the field of driving technology, specifically relating to a driving system and a vehicle. Background Technology

[0002] Currently, transport trucks, construction vehicles, and similar vehicles typically use the rear axle as the drive axle, driven by the engine to propel the vehicle. However, since the front axle lacks driving capability, the vehicle's traction significantly decreases or even completely disappears when driving on rough roads, leading to wheel slippage, a sharp decline in driving capability, and even complete loss of driving force, affecting the vehicle's power performance and overall passability. To address these issues, some vehicles employ a combination of a high-power engine and a transfer case. The high-power engine outputs power to both the front and rear axles through the transfer case to improve passability. However, the engine needs to drive both the front and rear axles simultaneously, significantly increasing power requirements and fuel consumption. Furthermore, adding a high-power engine and transfer case to the chassis occupies a lot of space, is costly, and presents installation layout difficulties, easily causing interference.

[0026] Detailed Implementation

[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0028] The driving system of this utility model is described below with reference to the accompanying drawings.

[0029] like Figures 1 to 4As shown, this utility model provides a driving system, which includes a first power mechanism 10 and a second power mechanism 20. The first power mechanism 10 includes a first drive member 11 and a front drive axle 12, with the first drive member 11 drivingly connected to the front drive axle 12. The second power mechanism 20 includes a second drive member 21, a transmission assembly 22, and a rear drive axle 23, with the second drive member 21 drivingly connected to the rear drive axle 23 via the transmission assembly 22. The front drive axle 12 and the rear drive axle 23 are spaced apart on the vehicle frame in the longitudinal direction, and the first drive member 11 and the second drive member 21 are also spaced apart on the frame in the longitudinal direction. It should be noted that the driving system of this utility model can be applied to vehicles such as transport trucks and engineering vehicles. This utility model does not limit the type of vehicle to which the driving system is applied. The vehicle includes a chassis assembly, which includes a frame for mounting the first power mechanism 10 and the second power mechanism 20 of the driving system.

[0030] Specifically, the first drive member 11 and the second drive member 21 are spaced apart on the vehicle frame. The first drive member 11 is driven by the front drive axle 12, and the second drive member 21 is driven by the rear drive axle 23 via the transmission assembly 22. During vehicle operation, the driving system can either activate only the first drive member 11 to drive the front drive axle 12 or only activate the second drive member 21 to drive the rear drive axle 23, thereby reducing energy consumption. Furthermore, when the vehicle is driving in adverse road conditions, the driving system can activate both the first drive member 11 and the second drive member 21 to synchronously drive the front drive axle 12 and the rear drive axle 23, improving traction. Yes, it effectively prevents wheel slippage and loss of control, improving vehicle driving safety and passability. Furthermore, the first drive component 11 and the second drive component 21 drive the front drive axle 12 and the rear drive axle 23 respectively, reducing the power requirements and energy consumption of the first drive component 11 and the second drive component 21. It can achieve synchronous drive of the front drive axle 12 and the rear drive axle 23 without the need for a high-power engine and transfer case. Moreover, the first drive component 11 and the second drive component 21 are spaced apart in the front-rear direction. Since the power requirements of the first drive component 11 and the second drive component 21 are small, both the first drive component 11 and the second drive component 21 can be small-volume drive components, reducing the space occupied, improving space utilization, facilitating installation, and having a reasonable layout, effectively preventing installation interference.

[0031] Those skilled in the art will understand that in the prior art, the horsepower range of high-power engines that can synchronously drive the front and rear axles through a transfer case is usually between 500 and 700 horsepower. These engines are large in size and expensive, and require a transfer case to operate, further occupying installation space and increasing operating costs exponentially. In the driving system of this invention, the horsepower of the first drive component 11 and the second drive component 21 is set to be above 280 horsepower to drive the front drive axle 12 and the rear drive axle 23 respectively, which significantly reduces power requirements and energy consumption. Furthermore, the low-power first drive component 11 and the second drive component 21 have the advantages of small size and low cost, which not only reduces space occupation and facilitates installation layout, preventing installation interference, but also eliminates the need for an additional transfer case, significantly reducing operating costs. In addition, the horsepower range of the first drive component 11 and the second drive component 21 can be flexibly selected according to actual usage. As long as the horsepower range enables the first drive component 11 to drive the front drive axle 12 and the second drive component 21 to drive the rear drive axle 23, it should be within the protection scope of this application.

[0032] In this embodiment of the utility model, the transmission assembly 22 includes a rear drive drive shaft 221, a second drive member 21 is disposed on the front mounting part of the vehicle frame, and a rear drive axle 23 is disposed on the rear mounting part of the vehicle frame. The two ends of the rear drive drive shaft 221 are respectively connected to the second drive member 21 and the rear drive axle 23 in a one-to-one correspondence. The second drive member 21 is driven connected to the rear drive axle 23 through the rear drive drive shaft 221.

[0033] like Figure 2 As shown, the vehicle frame has a front mounting section and a rear mounting section arranged sequentially in the front-to-back direction. The second drive component 21 and the rear drive axle 23 are respectively located on the front mounting section and the rear mounting section, which makes the weight distribution of the frame even and improves the driving stability of the vehicle. Moreover, the second drive component 21 is located in the front mounting section, which makes assembly, inspection and maintenance operations more convenient. The structure is reasonably arranged. One end of the rear drive shaft 221 is driven to the second drive component 21, and the other end of the rear drive shaft 221 is driven to the rear drive axle 23. This allows the second drive component 21 to drive the rear drive axle 23 through the rear drive shaft 221, thereby enabling the rear drive axle 23 to drive the vehicle. The transmission is smooth and stable, which further improves the power performance and adhesion performance.

[0034] In this embodiment of the utility model, the transmission assembly 22 further includes a middle drive axle 222, and the rear drive transmission shaft 221 includes an extension shaft section 2211 and a transition shaft section 2212. The two ends of the extension shaft section 2211 are respectively connected to the second drive member 21 and the middle drive axle 222, and the two ends of the transition shaft section 2212 are respectively connected to the middle drive axle 222 and the rear drive axle 23.

[0035] like Figure 1 , Figure 3and Figure 4 As shown, the middle drive axle 222 is mounted on the rear mounting section and located between the front drive axle 12 and the rear drive axle 23. One end of the extended shaft section 2211 is drivenly connected to the second drive member 21, and the other end of the extended shaft section 2211 is drivenly connected to the middle drive axle 222, so that the second drive member 21 can drive the middle drive axle 222 through the extended shaft section 2211. One end of the transition shaft section 2212 is drivenly connected to the middle drive axle 222, and the other end of the transition shaft section 2212 is drivenly connected to the rear drive axle 23, so that the second drive member 21 can drive the rear drive axle 23 in sequence through the extended shaft section 2211, the middle drive axle 222, and the transition shaft section 2212. The second drive member 21 can drive the middle drive axle 222 and the rear drive axle 23 simultaneously, so that both the middle drive axle 222 and the rear drive axle 23 are used to drive the vehicle, which improves the stability of the vehicle and can better adapt to harsh road conditions such as mud, gravel, and steep slopes, further improving the vehicle's passability.

[0036] In this embodiment of the invention, both the first drive member 11 and the front drive axle 12 are mounted on the front mounting portion, and the first drive member 11 is located below the driver's cab 200 of the vehicle. Figures 1 to 4 As shown, the first drive component 11 and the second drive component 21 are both located on the front mounting part, and the first drive component 11 and the second drive component 21 are spaced apart in the front-rear direction. This not only facilitates installation, inspection and maintenance, but also results in a compact structure, reducing the space occupied and improving space utilization. Furthermore, the first drive component 11 is located below the cab 200, which further improves the compactness of the front mounting part's structure, optimizes the spatial layout, and improves the uniformity of weight distribution, thereby improving driving stability and adhesion performance.

[0037] In this embodiment of the utility model, the first power mechanism 10 further includes a front drive shaft 13. The two ends of the front drive shaft 13 are respectively connected to the first drive member 11 and the front drive axle 12. The first drive member 11 is driven to the front drive axle 12 through the front drive shaft 13. The second drive member 21 is disposed between the first drive member 11 and the front drive axle 12 and is located above the front drive shaft 13.

[0038] like Figures 1 to 4As shown, since the first drive unit 11 is located below the cab 200, in order to move the installation position of the front drive axle 12 rearward to improve the uniformity of weight distribution and driving stability, a front drive shaft 13 is provided between the first drive unit 11 and the front drive axle 12. One end of the front drive shaft 13 is driven to the first drive unit 11, and the other end of the front drive shaft 13 is driven to the front drive axle 12. This allows the first drive unit 11 to drive the front drive axle 12 through the front drive shaft 13, thereby enabling the front drive axle 12 to drive the vehicle, improving the vehicle's adhesion and passability. Furthermore, the first drive unit 11 and the front drive axle 12 are spaced apart in the front-rear direction, resulting in a reasonable structural arrangement and improved driving stability. In addition, the second drive unit 21 is located behind the first drive unit 11, in front of the front drive axle 12, and above the front drive shaft 13, further improving the structural compactness, reducing the space occupied, improving space utilization, and effectively preventing installation interference.

[0039] In one embodiment of this utility model, the driving system further includes a driven axle 30, which is disposed on the front mounting portion and located between the first driving member 11 and the second driving member 21. Figure 1 As shown, a driven axle 30 is provided on the front mounting part of the frame to provide support, which helps to distribute the load and enhance the driving stability of the vehicle. Furthermore, the driven axle 30 is located between the first drive member 11 and the second drive member 21, which further improves the structural compactness. The installation layout is reasonable and effectively prevents installation interference.

[0040] In another embodiment of this utility model, the driving system further includes a driven axle 30, which is disposed on the front mounting portion and located behind the second driving member 21. Figure 4 As shown, a driven axle 30 is provided on the front mounting part of the frame to provide support, which helps to distribute the load and enhance the driving stability of the vehicle. The driven axle 30 is located behind the second drive member 21, which not only improves the structural compactness, but also shortens the length of the front drive shaft 13, thereby shortening the transmission path and enhancing the power transmission efficiency.

[0041] In this embodiment of the utility model, the driving system further includes a control device 40, which includes a controller 41 that is communicatively connected to the first drive member 11 and the second drive member 21, and the controller 41 is used to control the operating state of the first drive member 11 and the second drive member 21 respectively.

[0042] like Figure 5As shown, the controller 41 can control the first drive component 11 to start or stop operating, and can also control the second drive component 21 to start or stop operating. During vehicle operation, the controller 41 can control the first drive component 11 to start and the second drive component 21 to stop operating, so that the first drive component 11 drives the front drive axle 12 to drive the vehicle. Alternatively, the controller 41 can control the second drive component 21 to start and the first drive component 11 to stop operating, so that the second drive component 21 drives the rear drive axle 23 to drive the vehicle. The fact that only one of the first drive component 11 and the second drive component 21 is activated reduces energy consumption and improves energy efficiency. Furthermore, when the vehicle is driving in adverse road conditions such as mud, gravel, or steep slopes, the controller 41 can control the first drive component 11 to start and the second drive component 21 to start, so that the first drive component 11 and the second drive component 21 drive the front drive axle 12 and the rear drive axle 23 respectively, which greatly improves the adhesion performance, realizes multi-axle drive, and improves the vehicle's driving passability.

[0043] Furthermore, the control device 40 also includes a control panel 42, which is communicatively connected to the controller 41 and used for manually setting drive control commands. For example... Figure 5 As shown, the driver can manually set the drive control commands through the control panel 42. That is, the driver can control the first drive component 11 to start or stop operating, and control the second drive component 21 to start or stop operating, according to the road conditions. In good road conditions, the driver can control the first drive component 11 or the second drive component 21 to stop operating, so as to reduce energy consumption and save operating costs. In bad road conditions, the driver can control the first drive component 11 and the second drive component 21 to start, so as to improve the vehicle's passability. The operation is convenient and quick, and the use is flexible and reliable.

[0044] In this embodiment of the utility model, the first drive member 11 is configured as an engine or an electric motor, and the second drive member 21 is configured as an engine or an electric motor. Specifically, the first drive member 11 and the second drive member 21 can respectively adopt a gasoline engine, a diesel engine, a natural gas engine, or an electric motor in the prior art. As long as the drive member form enables the first drive member 11 to drive the front drive axle 12 and the second drive member 21 to drive the rear drive axle 23, it should fall within the protection scope of this application.
