Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0021] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0022] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0023] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0024] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings.

Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0028] According to a first aspect of the present invention, a braking system is provided, such as... Figures 1 to 2As shown, the braking system in this embodiment specifically includes a foot brake module and a handbrake module. The foot brake module is connected to the driver's cab control unit via hydraulic lines, while the handbrake module is electrically connected to the driver's cab control unit via sensor components. Thus, the parking brake can be activated by an electrical signal from the handbrake module, and the service brake can be activated by hydraulic fluid from the foot brake module. It should be noted that braking systems using hydraulic lines or sensors are already well-established in certain vehicle models; therefore, the principles of braking via hydraulic lines and sensor components, as well as the specific structures of the foot brake and handbrake modules, will not be elaborated upon further.

[0029] Specifically, the hydraulic pipeline of the foot brake module includes multiple pipes and valve components 42. In order to make the hydraulic pipeline more adaptable to the space layout requirements of the tractor, in this embodiment, the foot brake valve 21 in the valve component 42 is set at the rear end of the battery protective cover 1 (along the length direction of the tractor body) near the rear of the vehicle. That is, the foot brake valve 21, which occupies a large space, is distributed to make the pipes in the hydraulic pipeline more compact, beautiful and controllable.

[0030] like Figure 1 As shown, in this embodiment, the foot brake valve 21 is connected to the battery protective cover 1 via a first bracket. The first bracket includes a bent plate 221 with an L-shaped structure. The foot brake valve 21 is connected to the top of the horizontal section of the bent plate 221, and the vertical section of the bent plate 221 is connected to the battery protective cover 1. Furthermore, the bent plate 221 is fixed to both the foot brake valve 21 and the battery protective cover 1 using screw assemblies. In addition, the first bracket includes one or more reinforcing plates 222. These reinforcing plates 222 are formed in a triangular shape corresponding to the bent plate 221 and are correspondingly disposed within the recessed space of the bent plate 221. The first right-angled side of the reinforcing plate 222 is fixed to the bottom of the horizontal section of the bent plate 221, and the second right-angled side is fixed to the vertical section of the bent plate 221. The reinforcing plates 222 increase the structural strength of the first bracket, thereby improving the stability of the connection between the foot brake valve 21 and the battery protective cover 1.

[0031] It should be noted that the number of reinforcing plates 222 is not fixed. When there are multiple reinforcing plates 222, they are arranged at intervals along the width direction of the vehicle body. Furthermore, the connection method between the reinforcing plates 222 and the bent plates 221 is also not fixed; for example, they can be connected by welding. Preferably, although not shown in the figure, the reinforcing plates 222 and / or bent plates 221 can also be provided with through holes according to actual conditions to facilitate the passage of corresponding pipes or cables. These through holes can also serve as limiting constraints on the pipes or cables.

[0032] In this embodiment, multiple pipe fittings and valve components 42 in the hydraulic pipeline are assembled using a quick-connect assembly 3, thereby effectively improving the convenience of hydraulic pipeline assembly. Specifically, as shown... Figures 1 to 2 As shown, the quick-connect assembly 3 includes a base 31, which has an inner cavity and a plurality of first connection ports 311 and second connection ports 312 communicating with the inner cavity. The quick-connect assembly 3 also includes a first plug 32, the first end of which can be inserted into the first connection port 311 to realize the corresponding insertion of the first plug 32 and the base 31; the second end of the first plug 32 has a socket corresponding to the pipe fitting, that is, when the pipe fitting is inserted into the corresponding socket, the pipe fitting can communicate with the inner cavity of the base 31.

[0033] In addition, the quick-connect assembly 3 includes a second plug 33. The first end of the second plug 33 can be screwed into the second connection port 312, and the second end of the second plug 33 can be inserted into the valve component 42. That is, when the second end of the second plug 33 is inserted into the valve component 42, the valve component 42 can communicate with the inner cavity of the base 31, thereby realizing the corresponding communication between the pipe and the valve component 42.

[0034] Furthermore, the quick-connect assembly 3 also includes a locking element 34. For example... Figure 2 As shown, the outer ring of the second connection port 312 is formed into a square structure, and the first end of the locking member 34 is formed into a locking groove 341 corresponding to the square structure of the second connection port 312; the bottom end of the locking groove 341 is formed with a through hole to facilitate fitting onto the outer side wall of the second insert 33. Further, the inner side wall of the through hole is formed with internal teeth 342, the outer side wall of the second insert 33 is formed with an annular protrusion, and the outer side of the annular protrusion is formed with external teeth 331 that can mesh with the internal teeth 342.

[0035] When assembling the pipe body 41 and the valve component 42, the pipe body 41 can be pre-connected to the base via the first insert 32, and the locking member 34 can be fitted onto the outer side of the second connection port 312. Similarly, the valve component 42 can be pre-connected to the second insert 33. Then, the assembly of the valve component 42 and the second insert 33 is connected to the base. This effectively improves the efficiency and convenience of assembling the pipe body 41 and the valve component 42.

[0036] It should be noted that the tight and stable connection between two components through plugging is a conventional method in the mechanical field. Therefore, the specific plugging structure between the components in the quick-connect assembly 3 will not be described in detail, as long as the above technical effect can be achieved.

[0037] According to the braking system described above, the braking system is divided into a foot brake module and a handbrake module. The foot brake module is connected to the cab operating end via hydraulic lines, and the handbrake module is electrically connected to the cab operating end via sensor components. Thus, the parking brake can be activated by an electrical signal from the handbrake module, while the service brake can be activated by hydraulic fluid from the foot brake module. Compared to the rigid lever-operated braking system in the prior art, the hydraulic lines and cables can be flexibly connected to the tractor chassis, thereby adapting to a suspended cab.

[0038] Furthermore, the multiple pipe fittings and valve components 42 in the hydraulic pipeline of this utility model are assembled by the quick-connect assembly 3, which can effectively improve the convenience of assembly.

[0039] According to a second aspect of the present invention, a tractor is provided, wherein the tractor includes a braking system as described above; the hydraulic lines in the foot brake module and the cables in the handbrake module (for electrical connection) can be flexibly connected to the tractor chassis, and the specific connection position can be determined according to the actual situation.

[0040] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be defined by the protection scope of the claims.
