[0030] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.
[0031] The following is for reference. Figures 1-4 The description of the brake valve bracket 10 according to an embodiment of the present invention also proposes a chassis including the above-described brake valve bracket 10, and further proposes a vehicle including the above-described chassis.
[0032] The brake valve bracket 10 is located on the front side of the crossbeam 22 and is connected to the crossbeam 22. The brake valve bracket 10 includes a first plate portion 11 and a second plate portion 12, which are connected to each other. The first plate portion 11 is connected to the front side of the crossbeam 22, and the second plate portion 12 is used to install the brake valve 51. The brake valve bracket 10 is fixedly connected to the side of the front side of the crossbeam 22 through the first plate portion 11, thereby realizing the installation and fixation of the brake valve bracket 10.
[0033] The thickness of the brake valve bracket 10 can be between 2mm and 4mm. If the thickness of the brake valve bracket 10 is less than 2mm, its structural strength is low, and it may break under bumpy driving conditions after installation. If the thickness of the brake valve bracket 10 is greater than 4mm, its structural strength far exceeds the required strength, resulting in material waste and affecting the overall vehicle lightweight design. Preferably, the thickness of the brake valve bracket 10 is 3mm, ensuring both lightweight design and structural strength.
[0034] Combination Figure 1 and Figure 2 As shown, the second plate portion 12 and the first plate portion 11 are interconnected, with the second plate portion 12 located above the first plate portion. The second plate portion 12 is suitable for mounting the brake valve 51. Specifically, the second plate portion 12 is located above the first plate portion 11, providing a mounting point for the brake valve 51. The second plate portion 12 and the first plate portion 11 are located in the same vertical plane, allowing the brake valve bracket 10 to be connected to the front side of the crossbeam 22, suitable for the round tube crossbeam 22. The second plate portion 12 protrudes from the crossbeam 22, facilitating the installation and removal of the brake valve 51. The installation of the brake valve 51 can utilize the space above the crossbeam 22, saving space below the crossbeam 22 and preventing interference between the tubing connected to the brake valve 51 and the thrust rod assembly 30, thus avoiding impact on the overall vehicle braking performance. This brake valve bracket 10 has advantages such as reliable structure, convenient installation, and lightweight design, effectively solving the problem of increased vehicle cost caused by the newly developed brake valve bracket 10 and reducing system development costs.
[0035] In some embodiments, in the height direction, the upper surface of the first plate portion 11 can be flush with the upper surface of the crossbeam 22, then the second plate portion 12 is located above the crossbeam 22, which facilitates the assembly of the brake valve 51 on the second plate portion 12. At the same time, the brake valve 51 can utilize the space above the crossbeam 22, saving the space below the crossbeam 22.
[0036] Therefore, the brake valve bracket 10 can be connected to the front side of the crossbeam 22, and the second plate 12 is used to install the brake valve 51. This can effectively solve the problem of fixing the brake valve 51 of the round tube beam frame matching the X-arm suspension heavy truck model, ensuring the uniformity of the braking system layout when the whole vehicle is laid out, ensuring the universality of the whole vehicle layout and the lightweight of the brake valve bracket 10.
[0037] like Figure 1As shown, the first plate portion 11 is located below the second plate portion 12. The second plate portion 12 is used to install the brake valve 51. Therefore, the first plate portion 11 simultaneously supports both the second plate portion 12 and the brake valve 51. Thus, it is necessary to ensure the connection strength between the first plate portion 11 and the crossbeam 22. Therefore, one side of the first plate portion 11 protrudes from the second plate portion 12 in the vehicle width direction. On the one hand, this increases the contact area between the first plate portion 11 and the crossbeam 22, ensuring the connection strength between the brake valve bracket 10 and the crossbeam 22. On the other hand, the portion of the first plate portion 11 protruding from the second plate portion 12 can be connected to the crossbeam 22, facilitating the installation and removal of the brake valve bracket 10.
[0038] Furthermore, the first plate portion 11 protrudes beyond the second plate portion 12 on the other side in the vehicle width direction. That is, on the one hand, the contact area between the first plate portion 11 and the crossbeam 22 is further increased to ensure the connection strength between the brake valve bracket 10 and the crossbeam 22 and to ensure the reliability of the brake valve 51 installation; on the other hand, the portion of the first plate portion 11 that protrudes beyond the second plate portion 12 can be connected to the crossbeam 22, which facilitates the installation and removal of the brake valve bracket 10.
[0039] like Figure 2 As shown, a first opening 112 is provided on the first plate portion 11, and the first opening 112 faces downward to avoid related components. That is, the first opening 112 is located on the lower side of the first plate portion 11. A tube bundle is connected to the brake valve 51 on the brake valve bracket 10. On the one hand, the first opening 112 can limit the tube bundle, and the tube bundle can be connected to other components through the first opening 112; on the other hand, it reduces the weight of the brake valve bracket 10 and achieves weight reduction.
[0040] Combination Figure 2 As shown, the brake valve bracket 10 further includes a first fastener. A first mounting portion 111 is provided on the first plate portion 11. The first fastener passes through the first mounting portion 111 and is fixedly connected to the crossbeam 22. Specifically, the first mounting portion 111 is used to fix the brake valve bracket 10 to the crossbeam 22. The brake valve bracket 10 is fixed to the crossbeam 22 by connecting to the crossbeam 22 through the first mounting portion 111. The first fastener can pass through the first mounting portion 111 and be fixedly connected to the crossbeam 22, so that the brake valve bracket 10 is fixedly connected to the crossbeam 22.
[0041] In some embodiments, the first mounting portion 111 may be a first mounting hole, through which a first fastener passes and is fixedly connected to the crossbeam 22. Further, a third mounting hole may be provided on the crossbeam 22, through which the first fastener passes and the third mounting hole and is fixedly connected to the crossbeam 22.
[0042] There can be two first fasteners and two first mounting portions 111, located on both sides of the first opening 112 in the vehicle width direction. The two first fasteners correspond to the two first mounting portions 111 respectively, and after passing through the two first mounting portions 111, the two first fasteners are fixedly connected to the crossbeam 22, thereby improving the connection strength and reliability between the brake valve bracket 10 and the crossbeam 22.
[0043] Furthermore, the brake valve bracket 10 also includes a second fastener. A second mounting portion 121 is provided on the second plate portion 12. The second fastener passes through the second mounting portion 121 and is fixedly connected to the brake valve 51. Specifically, the second mounting portion 121 can abut against the brake valve 51 and is used for fixed connection with the brake valve 51. The second fastener can pass through the second mounting portion 121 and be fixedly connected to the brake valve 51, thereby mounting the brake valve 51 on the brake valve bracket 10.
[0044] In some embodiments, the second mounting part 121 can be a second mounting hole, and the second fastener passes through the second mounting hole and is fixedly connected to the brake valve 51. Further, the brake valve 51 can be provided with a fourth mounting hole, and the second fastener passes through the second mounting hole and the fourth mounting hole and is fixedly connected to the brake valve 51, thereby completing the installation and fixing of the brake valve 51.
[0045] Combination Figure 3 and Figure 4 As shown, the chassis according to the second aspect embodiment of the present invention includes: a frame, the frame including longitudinal beams 21 and crossbeams 22, the crossbeams 22 being transversely arranged between the longitudinal beams 21. Specifically, the chassis mainly consists of a frame, a thrust rod assembly 30, and a brake valve bracket 10, wherein the thrust rod assembly 30 is the chassis suspension, used to prevent the vehicle body from tilting too much when turning, thereby maintaining the stability of the entire vehicle.
[0046] Furthermore, the frame is mainly composed of longitudinal beams 21 and crossbeams 22. The crossbeams 22 are laterally arranged between the longitudinal beams 21. The longitudinal beams 21 may include a left longitudinal beam 21 and a right longitudinal beam 21 arranged in the vehicle width direction. The crossbeams 22 can serve as the balance shaft of the frame, thereby providing lateral support to the frame. The first plate portion 11 is connected to the front side of the crossbeam 22, thereby the brake valve bracket 10 is disposed on the front side of the crossbeam 22.
[0047] The crossbeam 22 is a circular tube crossbeam 22, within which an air storage space is formed. This air storage space can be used for vehicle braking. By incorporating the air storage space within the circular tube crossbeam 22, the function of the air tank can be integrated into the chassis, fully utilizing the chassis space and improving its practicality and integration. The circular tube crossbeam 22 has high structural strength, effectively ensuring the connection strength between the left and right longitudinal beams 21 on both sides of the vehicle, further improving chassis stability and enhancing vehicle performance.
[0048] The chassis also includes a thrust rod assembly 30, which can be used in the rear suspension system of a single rear axle or dual rear axle tractor. The thrust rod assembly 30 can ensure the stable connection between the tractor and the trailer or semi-trailer it tows, so that the tractor's traction force is stably transmitted to the trailer.
[0049] like Figure 3 As shown, the chassis also includes: an axle, and a thrust rod assembly 30 connected between the axle and the frame. Specifically, the axle includes: a center axle 41 and a rear axle 42. There can be two thrust rod assemblies 30. One thrust rod assembly 30 is connected between the center axle 41 and the front side of the crossbeam 22, and the other thrust rod assembly 30 is connected between the rear axle 42 and the rear side of the crossbeam 22.
[0050] The thrust rod assembly 30 includes a first thrust rod 31 and a second thrust rod 32. The first thrust rod 31 and the second thrust rod 32 are connected to the crossbeam 22. The first thrust rod 31 and the second thrust rod 32 are cross-fixed to each other, making the thrust rod assembly 30 an "X" shape. The thrust rod assembly 30 is positioned between the axle and the frame to prevent excessive tilting of the vehicle during cornering, ensuring vehicle stability. The thrust rod assembly 30 has two fixing points on both the frame and the axle to fix the first thrust rod 31 and the second thrust rod 32, preventing relative movement between the axle and the frame in the lateral and longitudinal directions, ensuring reliable connection between the axle and the frame, and guaranteeing vehicle stability.
[0051] Since the first thrust rod 31 and the second thrust rod 32 are fixed together, when lateral forces are transmitted between the axle and the frame, the thrust rod assembly 30 will bear the lateral forces, so that the vehicle body remains balanced and prevents the vehicle from tilting. This allows the thrust rod assembly 30 to improve the lateral stability of the vehicle.
[0052] According to the thrust rod assembly 30 of the present invention, the axle and the frame are connected by the first thrust rod 31 and the second thrust rod 32, ensuring the connection stability between the axle and the frame; the first thrust rod 31 and the second thrust rod 32 are fixed together, so that the thrust rod assembly 30 can transmit lateral force, and the thrust rod assembly 30 plays a lateral stabilizing role in the connection between the axle and the frame; the structure is simple, can effectively prevent the axle from moving, avoid vehicle tilting, reduce the number of parts, and reduce manufacturing costs.
[0053] By cross-fixing the first thrust rod 31 and the second thrust rod 32, the connection between the first thrust rod 31 and the second thrust rod 32 can be made more stable, which can effectively prevent lateral displacement between the axle and the frame. The "X"-shaped stabilizer bar structure can generate a force to prevent relative movement between the frame and the axle when the vehicle turns, thereby ensuring the stability of the connection between the frame and the axle. The "X"-shaped stabilizer bar structure occupies little space, has good structural strength, and effectively improves the stability of the vehicle.
[0054] According to some embodiments of this utility model, the second plate portion 12 protrudes beyond the crossbeam 22 in the height direction of the vehicle, facilitating the installation of the brake valve 51 and providing installation space for the brake valve 51.
[0055] According to some embodiments of the present invention, the chassis further includes: a central axle 41, which is disposed on the longitudinal beam 21 and located on the front side of the crossbeam 22. The central axle 41 can distribute the total weight on the front side of the crossbeam 22 more evenly and can also avoid the problem of rear overload or insufficient front load, thereby ensuring the balance of the front side of the crossbeam 22.
[0056] The thrust rod assembly 30 includes a central thrust rod assembly 30 located in front of the crossbeam 22, which is connected to the CRRC axle 41. The central thrust rod assembly 30 includes a first thrust rod 31 and a second thrust rod 32. One end of both the first thrust rod 31 and the second thrust rod 32 is connected to the front side of the crossbeam 22, and the other end of both is connected to the CRRC axle 41. Thus, the central thrust rod assembly 30 provides support force between the CRRC axle 41 and the crossbeam 22, thereby improving the strength and rigidity between the CRRC axle 41 and the crossbeam 22.
[0057] like Figure 3 As shown, the chassis also includes: a rear axle 42, which is mounted on the longitudinal beam 21 and located behind the crossbeam 22; and a thrust rod assembly 30, which includes a rear thrust rod assembly 30 located in front of the crossbeam 22 and connected to the rear axle 42. The rear axle 42's location behind the crossbeam 22 allows for a more even distribution of the total weight behind the crossbeam 22, thus ensuring the balance of the rear side of the crossbeam 22. One end of the rear thrust rod assembly 30 is connected to the rear axle 42, and the other end is connected to the rear side of the crossbeam 22. This allows the rear thrust rod assembly 30 to provide support between the rear axle 42 and the crossbeam 22, thereby improving the strength and rigidity between them.
[0058] The vehicle according to a third aspect of the present invention includes: the chassis described in the above embodiment.
