Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and more specifically, to a steering support and a vehicle. Background Technology

[0002] Steering bearings are important components in the steering systems of vehicles such as wide-body mining trucks. They connect steering tie rods and steering cylinders, withstand various forces and impacts from the road surface, and often need to adapt to harsh operating environments.

[0003] In related technologies, steering supports have certain deficiencies in strength under harsh operating environments, and are prone to breakage during long-term use. Furthermore, they cannot precisely limit the steering angle during vehicle steering. Utility Model Content

[0004] The present invention aims to solve the problems of existing steering supports being prone to breakage and unable to accurately limit the steering angle.

[0005] To address the aforementioned problems, in a first aspect, this utility model provides a steering support for connecting the front lower ring beam of a vehicle frame to the steering cylinder and the central steering arm. A steering tie rod is connected to the end of the central steering arm furthest from the front lower ring beam. The steering support includes a cover plate and a limiting support plate, both of which are fixedly connected to the front lower ring beam of the vehicle frame. Two cover plates are arranged in parallel, and two limiting support plates are provided and symmetrically fixed between the two cover plates. Along the length of the cover plates, the two limiting support plates divide the space between the two cover plates into a first mounting area in the middle and two second mounting areas at both ends. The cover plate is used to rotatably connect with the center steering arm in the first mounting area via a first pin. The cover plate is also used to rotatably connect with the two steering cylinders in the two second mounting areas via second pins. The limiting support plate is used to limit the steering of the steering cylinders and the center steering arm. A first reinforcing member is provided on the opposite outer sides of the two cover plates at the corresponding positions in the first mounting area. The first reinforcing member is used to reinforce the installation of the first pin. A second reinforcing member is provided in the second mounting area on the inner side of the two cover plates that are close to each other. The second reinforcing member is used to reinforce the installation of the second pin.

[0006] Optionally, the limiting support plate includes a first limiting support section and a second limiting support section fixedly connected. The second limiting support section is fixedly connected to the front lower ring beam of the vehicle frame. The first limiting support section is located at one end of the second limiting support section away from the front lower ring beam of the vehicle frame, and the first limiting support section is inclined relative to the second limiting support section toward the corresponding second mounting area.

[0007] Optionally, the steering support is located on the side of the front lower ring beam of the vehicle frame, and the steering support also includes a base plate. The cover plate and the second limiting support section are both fixedly connected to the front lower ring beam of the vehicle frame through the base plate.

[0008] Optionally, a second mounting hole and a first mounting hole are respectively provided through the two cover plates. The second mounting hole is located in the first mounting area, and the first mounting hole is located in the second mounting area. The second mounting hole is used to install the first pin, and the first mounting hole is used to install the second pin.

[0009] Optionally, there are two steering tie rods, one end of the center steering arm is connected to the two steering tie rods respectively by a third pin, and the other end of the center steering arm is located in the first mounting area by a first pin.

[0010] Optionally, the first reinforcing member includes two pads, which are respectively fixed on the outer surfaces of the two cover plates and arranged concentrically with the second mounting hole. The pads are used to fit around the first pin member.

[0011] Optionally, grooves are provided on the inner surfaces of the two adjacent cover plates, and the two grooves are arranged concentrically with the second mounting hole, and the grooves cooperate with the other end of the center steering arm.

[0012] Optionally, the second reinforcing member includes two mounting lugs, which are respectively disposed on the inner surfaces of the two cover plates, and are used to be sleeved around the second pin member.

[0013] Optionally, the two cover plates are arranged perpendicularly to the front lower ring beam of the vehicle frame, and the two limiting support plates are respectively arranged perpendicularly between the two cover plates, and the limiting support plates are fixed to the cover plates by welding.

[0014] The beneficial effects of this utility model's steering support are as follows: Two limiting support plates divide the space between the two cover plates into a first mounting area in the middle and second mounting areas at both ends. Thus, the steering arm, mounted on the first pin in the first mounting area, works in conjunction with the steering tie rod to achieve wheel steering. The steering cylinder, directly mounted on the second pin in the second mounting area, assists in wheel steering. The installation of the steering tie rod and the steering cylinder does not interfere with each other. The cover plates and limiting support plates form a box-like structure, which not only enhances the overall strength of the steering support but also allows the limiting support plates to accurately limit the steering angle of the steering cylinder and the central steering arm (mainly limiting the central steering arm). Furthermore, the limiting member ensures that the steering cylinder rotates stably around the second pin, thereby precisely limiting the vehicle's steering angle. Further, a first reinforcing member is located on the opposite outer sides of the two cover plates and within the first mounting area. The first and second reinforcing members enhance the connection strength between the center steering arm and the cover plate, thus enabling the steering tie rod connected to the center steering arm to operate stably. The second reinforcing member is located on the inner side of the two close cover plates and in the second mounting area, enhancing the connection strength between the steering cylinder and the cover plate. The second reinforcing member has a preset thickness, thereby adjusting the installation clearance of the second pin to prevent the steering cylinder from moving on the second pin. The first and second reinforcing members are arranged in a ring structure around the corresponding pins and on the inner and outer sides of the two cover plates, respectively. This also meets the characteristics that the center steering arm requires a large installation space for the connection position, while the steering cylinder requires a small installation space for the connection position. This allows the installation of the steering tie rod and the steering cylinder to be integrated into one unit. The first and second reinforcing members enhance the overall structural strength and ensure the operational stability of the steering system.

[0015] Secondly, this utility model also provides a vehicle including a steering support as described in any of the preceding claims.

[0016] The vehicle provided by this utility model has the same beneficial effects as the steering support has compared to the prior art, and will not be repeated here. Attached Figure Description

[0026] Reference Figure 1 , Figure 2 and Figure 3As shown in the figure, this utility model embodiment proposes a steering support for connecting the front lower ring beam 1 of the vehicle frame with the steering cylinder 15 and the central steering arm 16. The end of the central steering arm 16 away from the front lower ring beam 1 of the vehicle frame is connected to a steering tie rod 14. The steering support includes a cover plate 2 and a limiting support plate 3. Both the cover plate 2 and the limiting support plate 3 are fixedly connected to the front lower ring beam 1 of the vehicle frame. Two cover plates 2 are arranged in parallel, and two limiting support plates 3 are provided and symmetrically fixed between the two cover plates 2. Along the length direction of the cover plates 2, the two limiting support plates 3 divide the space between the two cover plates 2 into a first mounting area in the middle and two second mounting areas at both ends. The cover plate 2 is used to rotatably connect with the center steering arm 16 in the first mounting area via a first pin. The cover plate 2 is also used to rotatably connect with the two steering cylinders 15 in the two second mounting areas via second pins. The limiting support plate 3 is used to limit the steering of the steering cylinders 15 and the center steering arm 16. A first reinforcing member is provided on the opposite outer sides of the two cover plates 2 at the corresponding position in the first mounting area. The first reinforcing member is used to reinforce the installation of the first pin. A second reinforcing member is provided in the second mounting area on the inner side of the two cover plates 2 that are close to each other. The second reinforcing member is used to reinforce the installation of the second pin.

[0027] Specifically, the cover plate 2 is fixed to the front lower ring beam 1 of the vehicle frame. The cover plate 2 is connected to the steering cylinder 15 and the center steering arm 16. There are two steering cylinders 15, located at both ends of the cover plate 2, to realize left and right steering. Generally, one steering cylinder 15 corresponds to one steering tie rod 14. The steering tie rod 14 is connected to the center steering arm 16. The end of the steering tie rod 14 and the steering cylinder 15 that is away from the front lower ring beam 1 of the vehicle frame is used to connect directly or indirectly to the wheel. The steering tie rod 14 and the steering cylinder 15 work together to ensure that the vehicle can be steered accurately.

[0028] In this embodiment, two limiting support plates 3 divide the space between the two cover plates 2 into a first mounting area in the middle and second mounting areas at both ends. The central steering arm 16, mounted on the first pin in the first mounting area, works in conjunction with the steering tie rod 14 to achieve wheel steering. The steering cylinder 15, directly mounted on the second pin in the second mounting area, assists in wheel steering. The installation of the steering tie rod 14 and the steering cylinder 15 does not interfere with each other. The cover plates 2 and the limiting support plates 3 form a box-like structure, which not only enhances the overall strength of the steering support but also allows the limiting support plates 3 to accurately limit the steering angle of the steering cylinder 15 and the central steering arm 16 (primarily limiting the central steering arm 16). Furthermore, the limiting member ensures that the steering cylinder 15 rotates stably around the second pin, thereby precisely limiting the vehicle's steering angle. Further, a first reinforcing member is located on the opposite outer sides of the two cover plates 2 within the first mounting area, which enhances... The connection strength between the center steering arm 16 and the cover plate 2 ensures stable operation of the steering tie rod 14 connected to the center steering arm 16. The second reinforcing member is located on the inner side of the two close cover plates 2 and in the second mounting area, which enhances the connection strength between the steering cylinder 15 and the cover plate 2. The second reinforcing member has a preset thickness, which allows it to adjust the mounting clearance of the second pin to prevent the steering cylinder 15 from moving on the second pin. The first and second reinforcing members are arranged in a ring structure around the corresponding pins and on the inner and outer sides of the two cover plates 2, respectively. This also meets the characteristics that the center steering arm 16 requires a large mounting space for the connection position, while the steering cylinder 15 requires a small mounting space for the connection position. This allows the installation of the steering tie rod 14 and the steering cylinder 15 to be integrated into one unit. The first and second reinforcing members enhance the overall structural strength and ensure the operational stability of the steering system.

[0029] like Figure 1 As shown, in an optional embodiment of the present invention, the limiting support plate 3 includes a first limiting support section 301 and a second limiting support section 302 fixedly connected. The second limiting support section 302 is fixedly connected to the front lower ring beam 1 of the vehicle frame. The first limiting support section 301 is located at one end of the second limiting support section 302 away from the front lower ring beam 1 of the vehicle frame, and the first limiting support section 301 is inclined relative to the second limiting support section 302 toward the corresponding second installation area.

[0030] Specifically, the first limiting support section 301, as the main end of the limiting support plate 3, plays a major supporting role. It is fixedly connected to the top and bottom cover plates 2, and its inner end is fixed to the front lower ring beam 1 of the frame. The first limiting support section 301 and the second limiting support section 302 can be integrally formed, and the two are at a preset tilt angle. Each first limiting support section 301 is tilted towards its nearest second installation area, that is, the first installation area is in the shape of a flared mouth. Thus, the limiting support plate 3 composed of the first limiting support section 301 and the second limiting support section 302 can accurately limit the steering angle (actually, it limits the steering angle of the steering cylinder 15 and the center steering arm 16, mainly the center steering arm 16), so that steering can be achieved within the desired steering range.

[0031] Furthermore, such as Figure 1 and Figure 3 As shown, the edge of the cover plate 2 away from the front lower ring beam 1 of the frame is configured with a wavy structure. A first outer edge 11 is provided on the outer side of the cover plate 2 near the limiting support plate 3, and a second outer edge 12 is provided on the outer side of the cover plate 2 near the second mounting hole 6. The cover plate 2 configured in this way not only ensures that the weight can be appropriately reduced, but also ensures the connection strength at the pin connection position of the first mounting hole 4 and the second mounting hole 6, avoiding stress concentration. By processing specific transition fillets and reinforcing structures, the stress concentration problem is reduced while increasing the strength, thereby improving the fatigue strength and service life of the overall structure.

[0032] like Figure 1 and Figure 3 As shown, in an optional embodiment of the present invention, the steering support is disposed on the side of the front lower ring beam 1 of the vehicle frame, and the steering support also includes a base plate 10. The cover plate 2 and the second limiting support section 302 are both fixedly connected to the front lower ring beam 1 of the vehicle frame through the base plate 10.

[0033] Specifically, the beam structure of the front lower ring beam 1 of the frame is I-shaped. Direct fixation to its side may lead to instability. The components of the steering support are all located on the side wall of the front lower ring beam 1 of the frame. The beam structure of the front lower ring beam 1 of the frame is fixed by first setting a base plate 10, and then installing a cover plate 2 and a limiting support plate 3. The base plate 10 can be fixed to the beam structure of the front lower ring beam 1 of the frame by welding. Due to the addition of the base plate 10, the steering support is stably fixed, which is also conducive to the stable steering of the vehicle.

[0034] like Figure 1 and Figure 3As shown, in an optional embodiment of this utility model, a second mounting hole 6 and a first mounting hole 4 are respectively provided through the two cover plates 2. The second mounting hole 6 is located in the first mounting area, and the first mounting hole 4 is located in the second mounting area. The second mounting hole 6 is used to install the first pin, and the first mounting hole 4 is used to install the second pin.

[0035] Specifically, the second mounting hole 6 is used to install the first pin, which passes through the top and bottom second mounting holes 6 and limits the rotation of the end of the center steering arm 16 to the first mounting area. The first mounting hole 4 is used to install the second pin, which passes through the top and bottom first mounting holes 4 and limits the rotation of the end of the steering cylinder 15 to the first mounting area, thereby assisting in the steering of the steering system. As a result, all components of the steering support are made of high-strength steel plates, which greatly improves the load-bearing capacity.

[0036] like Figure 1 As shown, in an optional embodiment of this utility model, there are two steering tie rods 14, one end of the center steering arm 16 is connected to the two steering tie rods 14 respectively through a third pin, and the other end of the center steering arm 16 is located in the first mounting area through a first pin.

[0037] Specifically, the two steering tie rods 14 are connected to one end of the same central steering arm 16 in different directions, and the other end of the central steering arm 16 extends into the first mounting area. Thus, left and right steering along the X-axis direction is possible, and multiple connecting parts of the steering tie rods 14 are not required on the front lower ring beam 1 of the frame. This ensures the compactness of the structure while achieving all functions and structural stability. In this way, the two second mountings can be symmetrically arranged on both sides of the first mounting area, ensuring the overall compactness of the steering support structure and facilitating structural stability.

[0038] like Figure 2 and Figure 4 As shown, in an optional embodiment of this utility model, both the second and third pin components include a pin body. A limiting plate 13 is fixed around the pin body. Correspondingly, a limiting seat 9 is fixed on the cover plate 2 and the central steering arm 16, respectively. The limiting seat 9 is a retaining structure. The end of the limiting plate 13 away from the pin body is located inside the retaining structure. The retaining structure limits the rotation of the limiting plate 13, and the limiting plate 13 is confined within the limiting seat 9 by a limiting plate 17. The limiting plate 17 and the limiting seat 9 are connected by bolts. Thus, the limiting plate 17 and the limiting seat 9 limit the rotation of the pin body, thereby restricting the rotation of the second and third pin components. This allows the steering cylinder 15 to rotate stably around the second pin component, and the steering tie rod 14 to rotate stably around the third pin component. Correspondingly, both the second and third pin components are configured as cylindrical shafts.

[0039] like Figure 1 and Figure 3 As shown, in an optional embodiment of the present invention, the first reinforcing member includes two pads 8, which are respectively fixed on the outer surfaces of the two cover plates 2 and are arranged concentrically with the second mounting hole 6. The pads 8 are used to be sleeved on the periphery of the first pin member.

[0040] Specifically, the pad 8 is provided on the top surface of the upper cover plate 2 and the bottom surface of the lower cover plate 2, and can be fixed by welding. In this way, the top and bottom of the first pin are equivalent to being protected by an outer perimeter, which also plays the role of strengthening the overall structural strength.

[0041] like Figure 1 As shown, in an optional embodiment of the present invention, grooves 7 are respectively provided on the inner surfaces of the two cover plates 2 that are close to each other. The two grooves 7 are arranged concentrically with the second mounting hole 6, and the grooves 7 cooperate with the other end of the central steering arm 16.

[0042] Specifically, a groove 7 is provided on the inner surface of the cover plate 2 opposite to the second mounting area, so that the end of the second mounting hole 6 can be partially fitted into the groove 7. The groove 7 is preferably annular, which further expands the mounting space of the second mounting area for the center steering arm 16, and plays the role of positioning and ensuring stable rotation.

[0043] like Figure 1 As shown, in an optional embodiment of the present invention, the second reinforcing member includes two mounting ears 5, which are respectively disposed on the inner surface of the two cover plates 2, and are used to be sleeved on the periphery of the second pin member.

[0044] Specifically, mounting lugs 5 are located in each second mounting area and fixed to the inner surfaces of the cover plate 2. The end of the steering cylinder 15 passes through the second mounting area and is mounted on the cover plate 2 via a second pin. The second pin passes through the mounting lugs 5, so that the mounting lugs 5 are fitted around the second pin. The diameter of the second pin can be slightly larger (2-3 mm), and the mounting lugs 5 have a certain thickness, which can be selected according to the thickness. Thus, the mounting lugs 5 serve to increase structural strength and adjust the mounting gap.

[0045] like Figure 1 and Figure 3As shown, as an optional embodiment of this utility model, the two cover plates 2 are arranged perpendicularly to the front lower ring beam 1 of the frame, and are actually arranged perpendicularly to the bottom plate 10. The two limiting support plates 3 are respectively arranged perpendicularly between the two cover plates 2, and the limiting support plates 3 and the cover plates 2 are fixed by welding and surface finishing to form the box-type structure.

[0046] Specifically, the two cover plates 2 are arranged perpendicularly between the front lower ring beam 1 of the frame and the bottom plate 10. The limiting support plate 3 is arranged perpendicularly between the two cover plates 2. In short, the limiting support plate 3 is arranged symmetrically on the left and right, thus forming a box-type structure. The box-type structure is arranged along the vehicle body direction, which makes the overall stability of the steering support high and can withstand strong steering loads. The limiting support plate 3 is precision machined after welding, and the dimensions are strictly controlled to have extremely high surface precision. It can accurately limit the steering angle and ensure the design dimensions and installation accuracy of the steering cylinder 15 and the center steering arm 16. The box-type structure reduces the overall weight and disperses the concentrated stress.

[0047] On the other hand, the present invention also provides a vehicle including a steering support as described in any of the above embodiments.

[0048] The specific implementation of this embodiment can be referred to the aforementioned embodiment of the corresponding steering support, and will not be described again here.

[0049] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features of the present invention.

[0050] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
