Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a three-axle six-wheeled vehicle braking system and vehicle. Background Technology

[0002] Currently, three-axle vehicles primarily employ two types of braking systems. One type involves single-axle / two-axle or single-axle / three-axle braking, where each wheel is independently controlled, with no braking on the middle or rear axle. Since the vehicle's braking force equals the tire-to-ground adhesion coefficient multiplied by the ground's support force on the braking wheels, the limiting force generated when only some wheels are involved in braking is approximately 70%–80%, resulting in ineffective utilization of ground braking force and insufficient braking capacity. The other type involves six-wheel braking with independent control of each wheel. Because of this independent braking of all six wheels, real-time dynamic adjustment of the pressure in each circuit is required, leading to greater development difficulty, higher development and component costs, and lower actual efficiency due to its complex control.

[0003] Therefore, how to improve the efficiency and effectiveness of vehicle braking is an urgent problem to be solved. Utility Model Content

[0035] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0037] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0038] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0039] The main solution of this application is as follows: the three-axle six-wheel vehicle braking system includes a first axle, a second axle, and a third axle arranged sequentially from front to back, and also includes a braking electronic control system, a brake pipe, an air spring, and an air pipe; the brake pipe is connected to the braking electronic control system; two of the first axle, the second axle, and the third axle are connected by the brake pipe for braking on the same side; the air springs are respectively installed on the wheels of the second axle and the wheels of the third axle, and the air springs of the wheels on the same side are interconnected by air pipes.

[0040] Currently, there are two main types of three-axle automotive braking systems. One type involves single-axle / double-axle or single-axle / triple-axle braking, where each wheel is independently controlled, and the middle or rear axle is not braked. Since the vehicle's braking force equals the tire-to-ground adhesion coefficient multiplied by the ground's support force on the braking wheels, the limiting force generated when only some wheels are involved in braking is approximately 70%–80%, resulting in the vehicle not effectively utilizing ground braking force and its braking capacity not being fully realized. The other type is six-wheel braking, with each wheel independently controlled. Because of this independent braking of six wheels, the pressure in each circuit needs to be dynamically adjusted in real time according to the wheels, making the development of a six-wheel independent braking system more difficult, with higher development and component costs. Furthermore, its complex control leads to lower actual efficiency.

[0041] Therefore, how to improve the efficiency and effectiveness of vehicle braking is an urgent problem to be solved.

[0042] This application achieves simultaneous braking of the two axles (first, second, and third) via brake pipes, and connects the air springs of the wheels on the second and third axles on the same side using air pipes. The piping arrangement is simple, enabling simultaneous braking of the wheels on both sides of the same-side connection. By connecting the air springs on both sides of the rear wheels in the three-axle six-wheel vehicle braking system, the wheel pressure of each wheel is made equal in real time, maximizing the braking force of the corresponding vehicle and improving the braking performance and efficiency of the three-axle six-wheel vehicle braking system.

[0043] This application proposes a braking system for a three-axle, six-wheeled vehicle.

[0044] Reference Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of an embodiment of the three-axle six-wheel vehicle braking system of this application; Figure 2 This is a schematic diagram of another embodiment of the braking system for a three-axle, six-wheeled vehicle according to this application; Figure 3 This is a schematic diagram of the structure of another embodiment of the three-axle six-wheel vehicle braking system of this application; Figure 4 This is a schematic diagram of another embodiment of the three-axle six-wheel vehicle braking system of this application.

[0045] In the embodiments of this application, please refer to Figure 1 The three-axle six-wheel vehicle braking system includes a first axle 110, a second axle 120, and a third axle 130 arranged sequentially from front to back. Specifically, the first axle 110 is the front axle of the three-axle six-wheel vehicle braking system, the second axle 120 is the middle axle of the three-axle six-wheel vehicle braking system, and the third axle 130 is the rear axle of the three-axle six-wheel vehicle braking system. A wheel 190 is provided at both ends of the first axle 110, the second axle 120, and the third axle 130.

[0046] Among the first axle 110, the second axle 120, and the third axle 130, there is a brake interconnection on the same side of two axles; specifically, for any two axles among the first axle 110, the second axle 120, and the third axle 130, the brakes of the wheels on the same side of the two axles are interconnected. For example, when the two axles are the second axle 120 and the third axle 130, the left wheel brake of the second axle 120 and the left wheel brake of the third axle 130 are interconnected, and the right wheel brake of the second axle 120 and the right wheel brake of the third axle 130 are interconnected.

[0047] The wheels on the second axle 120 and the wheels on the third axle 130 are interconnected on the same side using air springs. In this embodiment, please refer to... Figure 1In the second axle 120 and the third axle 130, the wheels 190 on the same side are interconnected by air springs. Specifically, each wheel is equipped with an air spring, and the air springs of the wheels on the same side are interconnected by air hoses. By interconnecting the air springs of the middle and rear wheels on the same side, the wheel pressure of the wheels on the same side is made equal in real time, thereby improving the braking efficiency of the braking system of the three-axle six-wheeled vehicle.

[0048] In one feasible implementation, please refer to Figure 1 The braking system of the three-axle six-wheeled vehicle also includes a brake electronic control system 140 and a brake pipe 150;

[0049] The brake pipe 150 is connected to the brake electronic control system 140; two of the first shaft 110, the second shaft 120 and the third shaft 130 are connected by the brake pipe 150 for same-side braking interconnection.

[0050] In this embodiment, the braking system of the three-axle six-wheeled vehicle further includes a brake electronic control system 140 and a brake pipe 150. The brake pipe 150 is connected to the brake electronic control system 140, and the brakes of each wheel can be connected to the brake electronic control system 140 through the brake pipe 150, so that a designated electronic control system can control the brakes of each wheel through the brake pipe 150. The brake electronic control system 140 includes a hydraulic brake electronic control system 140 or a pneumatic brake electronic control system 140.

[0051] Among them, any two of the first shaft 110, the second shaft 120 and the third shaft 130 are connected by brake pipe 150 for same-side braking interconnection. The brakes on the same side of the two shafts are connected by brake pipe 150 respectively. For example, when the two shafts are the second shaft 120 and the third shaft 130, the left wheel brake of the second shaft 120 and the left wheel brake of the third shaft 130 are connected to the same brake pipe, and the right wheel brake of the second shaft 120 and the right wheel brake of the third shaft 130 are connected to the same brake pipe.

[0052] Among them, the shafts of the first shaft 110, the second shaft 120 and the third shaft 130, except for the two shafts that are connected to the brake on the same side, are independently connected to the brake electronic control system through the brake pipe. That is to say, the shafts other than the two shafts that are connected to the brake on the same side are independently connected to the brake electronic control system through separate brake pipes.

[0053] In one feasible implementation, please refer to Figure 1 and Figure 2 The brake pipe 150 includes a first brake pipe 151 and a second brake pipe 152;

[0054] Two of the first shaft 110, the second shaft 120 and the third shaft 130 are connected to the second shaft 152 for same-side braking via the first brake pipe 151.

[0055] In this embodiment, the brake pipe 150 includes a first brake pipe 151 and a second brake pipe 152. The first brake pipe 151 and the second brake pipe 152 are respectively connected to the brake electronic control system 140. Any two shafts among the first shaft 110, the second shaft 120, and the third shaft 130 are connected to each other for same-side braking through the first brake pipe 151 and the second brake pipe 152. For example, when the two shafts are the second shaft 120 and the third shaft 130, the left wheel brake of the second shaft 120 and the left wheel brake of the third shaft 130 are respectively connected to the first brake pipe. The brake electronic control system 140 controls the left wheel brake of the second shaft 120 and the left wheel brake of the third shaft 130 simultaneously through the first brake pipe. The right wheel brake of the second shaft 120 and the right wheel brake of the third shaft 130 are respectively connected to the second brake pipe. The brake electronic control system 140 controls the right wheel brake of the second shaft 120 and the right wheel brake of the third shaft 130 simultaneously through the second brake pipe.

[0056] In one feasible implementation, the left wheel brake corresponding to the second shaft 120 and the left wheel brake corresponding to the third shaft 130 are respectively connected to the first brake pipe 151.

[0057] The right wheel brake corresponding to the second shaft 120 and the right wheel brake corresponding to the third shaft 130 are respectively connected to the second brake pipe 152.

[0058] In the embodiments of this application, please refer to Figure 1 and Figure 2 When two of the three shafts 110, 120, and 130 are the second shaft 120 and the third shaft 130, the left wheel brake corresponding to the second shaft 120 and the left wheel brake corresponding to the third shaft 130 are respectively connected to the first brake pipe 151. That is, the brake electronic control system 140 controls the left wheel brake of the second shaft 120 and the left wheel brake of the third shaft 130 simultaneously through the first brake pipe. The right wheel brake corresponding to the second shaft 120 and the right wheel brake corresponding to the third shaft 130 are respectively connected to the second brake pipe 152. That is, the brake electronic control system 140 controls the right wheel brake of the second shaft 120 and the right wheel brake of the third shaft 130 simultaneously through the second brake pipe.

[0059] It should be noted that the right wheel brake and the left wheel brake of the first axle 110 can be connected to the brake electronic control system 140 independently. That is, the right wheel brake of the first axle 110 is connected to the brake electronic control system 140 through a brake pipe, and the left wheel brake of the first axle 110 is connected to the brake electronic control system 140 through another brake pipe, so that the brake electronic control system 140 can independently control the braking of the right wheel and the left wheel of the first axle 110.

[0060] In one feasible implementation, the left wheel brake corresponding to the first shaft 110 and the left wheel brake corresponding to the third shaft 130 are respectively connected to the first brake pipe 151.

[0061] The right wheel brake corresponding to the first shaft 110 and the right wheel brake corresponding to the third shaft 130 are respectively connected to the second brake pipe 152.

[0062] In this embodiment of the application, when two of the three shafts—the first shaft 110, the second shaft 120, and the third shaft 130—are the first shaft 110 and the third shaft 130, the left wheel brake corresponding to the first shaft 110 and the left wheel brake corresponding to the third shaft 130 are respectively connected to the first brake pipe 151. That is, the brake electronic control system 140 controls the left wheel brake of the first shaft 110 and the left wheel brake of the third shaft 130 simultaneously through the first brake pipe. The right wheel brake corresponding to the first shaft 110 and the right wheel brake corresponding to the third shaft 130 are respectively connected to the second brake pipe 152. That is, the brake electronic control system 140 controls the right wheel brake of the first shaft 110 and the right wheel brake of the third shaft 130 simultaneously through the second brake pipe.

[0063] It should be noted that the right wheel brake and the left wheel brake of the second axle 120 can be connected to the brake electronic control system 140 independently. That is, the right wheel brake of the second axle 120 is connected to the brake electronic control system 140 through a brake pipe, and the left wheel brake of the second axle 120 is connected to the brake electronic control system 140 through another brake pipe, so that the brake electronic control system 140 can independently control the braking of the right wheel and the left wheel of the second axle 120.

[0064] In one feasible implementation, the left wheel brake corresponding to the first shaft 110 and the left wheel brake corresponding to the second shaft 120 are respectively connected to the first brake pipe 151.

[0065] The right wheel brake corresponding to the first shaft 110 and the right wheel brake corresponding to the second shaft 120 are respectively connected to the second brake pipe 152.

[0066] In this embodiment, when two of the three shafts—first shaft 110, second shaft 120, and third shaft 130—are first shaft 110 and second shaft 120, the left wheel brake corresponding to first shaft 110 and the left wheel brake corresponding to second shaft 120 are respectively connected to first brake pipe 151. That is, the brake electronic control system 140 controls the left wheel brake of first shaft 110 and the left wheel brake of second shaft 120 simultaneously through the first brake pipe. The right wheel brake corresponding to first shaft 110 and the right wheel brake corresponding to second shaft 120 are respectively connected to second brake pipe 152. That is, the brake electronic control system 140 controls the right wheel brake of first shaft 110 and the right wheel brake of second shaft 120 simultaneously through the second brake pipe.

[0067] It should be noted that the right wheel brake and the left wheel brake of the third axle 130 can be connected to the brake electronic control system 140 independently. That is, the right wheel brake of the third axle 130 is connected to the brake electronic control system 140 through one brake pipe, and the left wheel brake of the third axle 130 is connected to the brake electronic control system 140 through another brake pipe, so that the brake electronic control system 140 can independently control the braking of the right wheel and the left wheel of the third axle 130.

[0068] In one feasible implementation, the three-axle six-wheel vehicle braking system further includes an air spring and an air hose;

[0069] The air springs are respectively installed on the wheels of the second axle 120 and the wheels of the third axle 130, and the air springs of the wheels on the same side are interconnected by air pipes.

[0070] In the embodiments of this application, please refer to Figure 1 and Figure 2 The three-axle six-wheel vehicle braking system also includes air springs and air hoses. There can be four air springs, one for each wheel on the second axle (120) and the third axle (130). The air springs on the same side of the wheels are interconnected by air hoses. This interconnection of the air springs on the middle and rear wheels on the same side ensures that the wheel pressure on the same side is equal in real time, improving the braking efficiency of the three-axle six-wheel vehicle braking system.

[0071] In one feasible implementation, the air spring includes a first air spring 161 and a second air spring 162, and the air pipe includes a first air pipe 170;

The bottom end of the second air spring 162 is connected to the second H-arm 182 to be fixed to the second H-arm 182, and the top end of the second air spring 162 communicates with the first air pipe 170. The first air pipe 170 includes two air pipes, and the two ends of each first air pipe 170 are respectively connected to the top end of the first air spring 161 and the top end of the second air spring 162.

[0077] In other words, one end of the first air spring 161 is connected to the first H-arm 181, one end of the second air spring 162 is connected to the second H-arm 182, and the first air pipe 170 is simultaneously connected to both the first air spring 161 and the second air spring 162, so as to realize the interconnection of the left middle and rear wheel air springs of the three-axle six-wheel vehicle braking system, so that the wheel pressure of the left wheel is equal in real time, thereby improving the braking efficiency of the three-axle six-wheel vehicle braking system.

[0078] In one possible implementation, the air spring includes a third air spring and a fourth air spring, and the air tube includes a second air tube;
