[0029] As shown in Figures 1-2 The utility model provides a front suspension longitudinal push support 1, which comprises:
[0030] A pair of main vertical plates 101, the pair of main vertical plates 101 is parallel and opposite arrangement;
[0031] A top plate 102 is arranged at the top of the pair of main vertical plates 101 and is used for connecting the pair of main vertical plates 101.
[0032] A fixed pipe 103 is arranged between the pair of main vertical plates 101 and is used for mounting a push rod.
[0033] The front suspension longitudinal push support is usually installed in pairs on a vehicle frame in use, the top surface of the top plate is connected with the lower wing surface of the longitudinal beam of the vehicle frame, and a pipe beam 2 is connected between the pair of front suspension longitudinal push supports 1, as shown in Figure 1
[0034] In the above embodiment, the pair of parallel and opposite main vertical plates 101 of the front suspension longitudinal push support 1 can effectively disperse the force borne. When the vehicle runs on a rugged off-road road surface, such as a mine site, it will be subjected to impact forces from all directions, including upward and downward forces generated by vehicle bumping, lateral forces during turning and the like. The main vertical plate 101 can uniformly distribute these forces on its own structure, avoiding excessive local stress and causing structural damage. At the same time, this parallel arrangement also provides a stable support frame for the entire support. For example, when the fixed pipe 103 of the front push rod is subjected to a pushing force, the main vertical plate 101 can resist deformation like two strong pillars, ensuring the stability of the position of the fixed pipe 103, thereby ensuring that the front push rod can normally function and maintain the stability of the vehicle suspension system.
[0035] The top plate 102 is connected with the lower wing surface of the longitudinal beam of the vehicle frame, so that the support and the vehicle frame form an integral structure. During vehicle operation, it can effectively transmit the force from the front suspension part to the longitudinal beam of the vehicle frame. Since the longitudinal beam of the vehicle frame is the main load-bearing component of the vehicle frame, it has high strength and rigidity, and through the connection of the top plate 102, the force borne by the support can be well dispersed and carried.
[0036] The fixed tube 103 is used to fix the front thrust rod and transmit the force borne by the front thrust rod to the main vertical plate 101. The connection between the main vertical plates 101 enables the fixed tube 103 to be effectively supported in all directions. During the driving of the vehicle, the front thrust rod can be subjected to tensile or compressive force, and the fixed tube 103 can stably maintain its position through the support of the main vertical plate 101 to prevent displacement or deformation. This connection mode ensures the fixing reliability of the front thrust rod, so that the front thrust rod can accurately play its function of controlling the front suspension movement of the vehicle.
[0037] In addition, the front suspension longitudinal thrust support 1 is connected with the tube beam 2 to form a stable frame structure. The two supports can jointly bear the force borne by the front suspension part of the vehicle, and during the driving of the vehicle, whether it is subjected to vertical road bumping impact force or horizontal acceleration, deceleration or turning force, the force can be effectively dispersed through the structure composed of the two supports and the tube beam 2. For example, when the front wheel on one side of the vehicle encounters a large pit, the support on this side bears a large vertical upward force, at this time, through the connection of the tube beam 2, the force can be transmitted to the support on the other side, avoiding damage to the single support due to excessive force, and enhancing the stability of the entire front suspension mounting structure.
[0038] The tube beam 2 serves as a component connecting the two supports and can limit the relative displacement between the two supports. In complex off-road working conditions, the front suspension part of the vehicle is prone to vibration and torsional deformation. The tube beam 2 tightens the two supports and keeps them in a relatively fixed positional relationship, thereby ensuring the integrity of the front suspension part structure and improving the reliability of the vehicle front suspension system.
[0039] Further, the top plate 101 is provided with recesses at the front end and the rear end. By providing the recesses, the weld between the top plate and the lower flange of the frame longitudinal beam is curved, compared with the straight weld when no recesses are provided. The curved weld effectively prolongs the connection length of the top plate and the lower flange of the frame longitudinal beam, making the welding more firm.
[0040] Further, the main vertical plate 101 is in the shape of an inverted trapezoid.
[0041] The main vertical plate 101 is designed in the shape of an inverted trapezoid, which has been fully considered. The upper side is longer, which significantly increases the fixing area with other components, thereby improving the stability and reliability of the connection. The lower side is shorter, which effectively reduces the transverse area and can skillfully avoid the potential risk of collision with external objects, thereby enhancing the applicability and safety of the entire front suspension longitudinal thrust support in complex working conditions.
[0042] Further, the fixed tube 103 is provided with a support tube 104 parallel to the main vertical plate 101, which is horizontally arranged to be fixedly connected between the opposite inner walls of the fixed tube 101.
[0043] The support tube 104 is connected between the opposite inner walls of the fixed tube 103, like a "skeleton" inside the fixed tube 103, enhancing the bending and torsion resistance of the fixed tube 103, so that the fixed tube 103 can better maintain its shape, ensuring the installation accuracy and stability of the front thrust rod. This reinforcing method can significantly prolong the service life of the fixed tube 103. Due to the high intensity of mine transportation work, if the fixed tube 103 does not have enough strength support, it is easy to be damaged, and the presence of the support tube 104 reduces the risk of damage to the fixed tube 103 due to frequent stress, reducing maintenance costs and replacement frequency.
[0044] Further, the fixed tube 103 is provided with two, including:
[0045] The first fixed tube 1031 is fixedly arranged at the middle or upper part between a pair of main vertical plates 101;
[0046] The second fixed tube 1032 is fixedly arranged at the lower part between a pair of main vertical plates 101;
[0047] Among them, the first fixed tube 1031 and the second fixed tube 1032 are both rectangular tubes.
[0048] Setting two fixed tubes 103 (the first fixed tube 1031 and the second fixed tube 1032) can more effectively disperse the force transmitted by the front thrust rod. During the operation of the off-highway mining dump truck, the front thrust rod will be subjected to complex forces from different directions and working conditions, such as impact forces generated during vehicle acceleration, deceleration, turning, or driving on rough roads. Two fixed tubes 103 can disperse these forces to different positions, avoiding force concentration in one point or one area, and reducing the load pressure of a single fixed tube 103.
[0049] The first fixed tube 1031 is located at the middle or upper part of the main vertical plate 101, and the second fixed tube 1032 is located at the lower part of the main vertical plate 101. This upper and lower distribution method makes the force in the vertical direction be reasonably distributed. The first fixed tube 1031 at the middle or upper part can mainly bear the horizontal thrust and tension, as well as part of the vertical component force, while the second fixed tube 1032 at the lower part can not only share the horizontal force, but also better bear the larger vertical downward force due to factors such as vehicle bumping and cargo weight, since it is located closer to the vehicle chassis. This helps the entire front suspension longitudinal push support 1 of the vehicle frame to better withstand various forces acting on the front suspension part of the vehicle.
[0050] The fixed tube 103 adopts a rectangular tube, and the four corners of the rectangular tube can provide better resistance to torsional deformation. When the fixed tube 103 is subjected to force (such as thrust, tension, lateral force, etc.) from the front thrust rod, the corner structure of the rectangular tube can resist deformation like a “stiffener”. Especially when the vehicle drives on complex road conditions off the road and is subjected to impact in various directions, the rectangular tube can effectively maintain its shape and ensure the stability of the front thrust rod mounting position. At the same time, the production process of the rectangular tube is relatively simple, and can be more efficient in cutting, welding and other processing links. Compared with a box made of single plates, the rectangular tube has fewer welds and good processability.
[0051] Further, the support tube 104 is a circular tube.
[0052] The support tube 104 is a circular tube, which has good performance in material mechanics for bearing axial force and torsional force. Moreover, the circular tube is easy to obtain in the market and has relatively stable price, which can effectively control the material cost while ensuring the structural strength. Its standard circular shape is also convenient for cutting and installation in processing, reducing processing cost.
[0053] Further, the front end of the first fixed tube 1031 is provided with a first groove, and the rear end of the first fixed tube 1032 is provided with a second groove.
[0054] The front end of the first fixed tube 1031 is provided with a first groove, mainly based on the installation requirements of the thrust rod. By setting the groove, the thrust rod can be provided with a precisely fitted mounting position, ensuring the stability and coaxiality of the installed thrust rod, and effectively guaranteeing the force transmission efficiency and reliability. The rear end of the first fixed tube 1031 is provided with a second groove, which is considered for process optimization. In the welding operation, if no groove is set, the welding of the support tube 104 and other components can only achieve half-circle welding, which greatly affects the welding strength and stability. After the second groove is set, more favorable operation space can be created for the welding of the support tube 104, so that the support tube 104 can realize full-circle welding, significantly improving the welding quality and enhancing the stability of the overall structure.
[0055] Further, the lower end of the second fixed tube 1032 is provided with a third groove, which is mainly based on the demand of the installation of the thrust rod. By setting the groove, the installation position of the thrust rod can be accurately matched, the stability and coaxiality of the thrust rod after installation can be ensured, and the force transmission efficiency and reliability can be effectively guaranteed. The design of the third groove can provide a position for the welding of the support tube 104 and create a more favorable operation space for the welding of the support tube 104, so that the support tube 104 can be fully welded, and the welding quality and the stability of the overall structure are significantly improved. In addition, when the vehicle runs on the rugged mine road, the second fixed tube 103 will bear forces from all directions, such as vertical impact force (due to vehicle bumping) and horizontal thrust (from the front thrust rod). The presence of the third groove can change the stress distribution of the fixed tube 103, so that the stress is dispersed to a certain extent around the groove. This stress release mechanism helps to avoid excessive stress concentration at the lower end of the fixed tube 103, reducing the possibility of damage to the fixed tube 103 due to stress concentration.
[0056] At the same time, the presence of the third groove can reduce the weight of the second fixed tube 1032. In the mine dump truck, reducing the weight of the vehicle parts helps to reduce the self-weight of the whole vehicle, so that there is a certain space for improvement in the carrying capacity of the vehicle.
