Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts, and in particular to a V-shaped automotive thrust rod assembly with a mounting base. Background Technology

[0002] The V-type automotive thrust rod assembly is a key component of the automotive chassis suspension system. It is mainly used to transmit longitudinal forces, lateral forces, and torques during vehicle operation. It is widely used, especially in the non-independent suspension of commercial vehicles, such as trucks, buses, and trailers. Its core function is to limit excessive axle displacement and ensure vehicle stability and handling.

[0003] The existing announcement number is CN218661202U, which discloses a V-type thrust rod assembly for heavy-duty vehicle suspension. This assembly includes a V-type thrust rod assembly and a connecting mechanism for fixing the V-type thrust rod assembly to the vehicle. The V-type thrust rod assembly consists of a first connecting rod, a second connecting rod, a V-type ball seat assembly, and two straight ball seat assemblies. By manually engaging sleeves onto the outer walls of the first and second connecting rods, the support rods are hinged on opposite surfaces of a fixed plate via pull rods. After hinge engagement, the bolts are manually rotated to fix the sleeves to the first and second connecting rods via folded edges. This effectively strengthens the support of the first and second connecting rods, enhancing their robustness and protection, preventing deformation and damage during prolonged use, and improving the service life of the V-type thrust rod assembly.

[0004] While the aforementioned features allow the sleeve to be fixedly connected to the first and second connecting rods via the folded edge, effectively reinforcing and supporting the first and second connecting rods and preventing deformation and damage over prolonged use, and the four sets of screw holes and corresponding bolts can secure the base to some extent, this single-point, distributed connection method is insufficient for evenly bearing forces in all directions, especially for vehicles subjected to heavy loads such as large trucks. When the vehicle turns, brakes, or traverses bumpy roads, the base may experience slight vibrations. Over time, this will exacerbate wear between the bolts and screw holes, leading to increased connection gaps and further reducing connection stability. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a V-shaped automotive thrust rod assembly with a mounting base.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A V-shaped automotive thrust rod assembly with a mounting base includes a mounting base, a V-shaped ball joint assembly mounted on one end of the mounting base, connecting rods mounted on one and the other ends of the V-shaped ball joint assembly, straight ball joint assemblies mounted on one end of each of the two sets of connecting rods, rod bodies rotatably connected to one and the other ends of the mounting base, blocks rotatably connected to one end of each of the two sets of rod bodies, and bolts threadedly connected to one and the other ends of each of the two sets of blocks.

[0008] Preferably, one end of the mounting base is connected to a plate, and multiple sets of mounting holes are provided on both sets of the plates.

[0009] Preferably, both sets of blocks are designed with bosses at the threaded connection points with the corresponding bolts.

[0010] Preferably, each of the multiple sets of bolts has a knob connected to one end.

[0011] Preferably, one end of each of the multiple sets of knobs is connected to a washer.

[0012] Preferably, the multiple sets of mounting holes are evenly distributed on the corresponding plate.

[0013] Preferably, the mounting base has multiple sets of mounting holes.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By coordinating the rod, bolt, and block, the rod is rotated to make the block fit against the longitudinal or transverse beam interface of the vehicle's underframe or axle. The bolt is then screwed into the pre-drilled bolt holes, providing oblique support to the mounting base and dispersing stress. When the mounting base is subjected to longitudinal traction or braking force transmitted from the axle, the oblique bracket can distribute some of the force to the longitudinal or transverse beams of the frame or axle, preventing the force from being concentrated at the original connection point. When the vehicle turns or experiences lateral forces due to bumps, the oblique tension of the bolt can balance the reaction force of the block, further offsetting the lateral impact. When the vehicle brakes suddenly, the reverse torque generated by the braking force is resolved by the shear force of the bolt and the supporting force of the block, which to some extent prevents the mounting base from loosening due to excessive instantaneous force.

[0016] 2. Through the fit between the plate, mounting base, and mounting hole one, the plate and the web of the longitudinal beam of the frame are fastened together by multiple sets of external bolts passing through mounting hole one, forming an interconnected integral structure. This structure can effectively resist torsional and bending deformation. When the vehicle is turning or encountering lateral forces, the multiple connection points work together to prevent relative displacement between the plate and the web of the longitudinal beam of the frame, ensuring that the mounting base maintains a stable posture during force transmission, thereby ensuring that the V-type thrust rod assembly can properly perform its function of limiting axle displacement.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, referring to Figures 1 to 5A V-shaped automotive thrust rod assembly with a mounting base includes a mounting base 1, a V-shaped ball joint assembly 2 mounted on one end of the mounting base 1, a connecting rod 3 mounted on one end and the other end of the V-shaped ball joint assembly 2, and a straight ball joint assembly 4 mounted on one end of each of the two sets of connecting rods 3. The V-shaped ball joint assembly 2 serves as the force transmission hub, and the connecting rods 3 mounted at both ends of the V-shaped ball joint assembly 2 are respectively connected to the straight ball joint assembly 4 to form a V-shaped force transmission path. When the vehicle is in motion, the longitudinal traction, braking force, and lateral force generated by the axle are transmitted to the connecting rod 3 through the straight ball joint assembly 4, and then converge at the mounting seat 1 through the V-shaped ball joint assembly 2. Finally, the force is distributed to the frame by the mounting seat 1, completing the basic force transmission cycle. One end of the mounting seat 1 is rotatably connected to a rod 5, and one end of each of the two sets of rods 5 is rotatably connected to a block 6. One end of each of the two sets of blocks 6 is threadedly connected to a bolt 7. Rotating the rod 5 causes the block 6 to fit against the interface of the longitudinal beam or cross beam of the frame. After the bolt 7 is screwed in, an oblique support system is formed. To a certain extent, the stress can be dispersed along two paths: the axis of the bolt 7 and the contact surface of the block 6. Part of the stress is transmitted to the rigid structure of the frame or axle through the bolt 7, and the other part is diffused to a wider area through the large-area contact between the block 6 and the interface. To a certain extent, the stress value per unit area is reduced, thereby avoiding the need to enhance connection stability.

[0025] In this embodiment, mounting base 1 has plates 10 connected to both ends. Multiple sets of mounting holes 11 are formed on both plates 10. These mounting holes 11, in conjunction with external bolts, connect the plates 10 to the web of the longitudinal beam of the vehicle frame, distributing localized stress over a larger area and thus offering wider applicability. Both sets of blocks 6 have bosses at their threaded connections to the corresponding bolts 7. These bosses increase the material thickness at the connection point, allowing the area to withstand greater tightening and shearing forces. Each bolt 7 has a knob 8 connected to one end, facilitating easier rotation. Each knob 8 also has a washer 9 connected to one end, absorbing vibration and preventing bolt loosening. The mounting holes 11 are evenly distributed on the corresponding plates 10, ensuring more uniform stress distribution at the connection point between the plates 10 and the web of the longitudinal beam. The mounting base 1 has multiple sets of mounting holes 12. By cooperating with the external bolts through the mounting holes 12, the mounting base 1 can be fixed to the corresponding position on the vehicle frame.

[0026] The working principle of this embodiment is as follows: In use, the mounting seat 1 can be fixed to the corresponding position on the frame by cooperating with the external bolts through the mounting hole 12. By rotating the rod 5, the block 6 is made to fit with the interface of the frame's longitudinal beam or cross beam. After screwing in the bolt 7, an oblique support system is formed. When the mounting seat 1 is subjected to longitudinal force, the bolt 7 distributes part of the load to the rigid structure of the frame. When encountering lateral force or bumpy impact, the shear force of the bolt 7 and the reaction force of the block 6 are balanced, offsetting the lateral impact and avoiding stress concentration at a single connection point. The plates 10 on both sides of the mounting seat 1 are connected to the web of the frame's longitudinal beam through multiple sets of mounting holes 11, forming a surface-area fixing structure. The multi-point connection achieved by multiple sets of external bolts passing through the mounting holes 11 spreads the local force to a larger area, effectively resisting torsional and bending deformation to a certain extent. When the vehicle turns and generates lateral moment, the rigid connection between the plate 10 and the frame can prevent the mounting seat 1 from shifting, ensuring the limiting accuracy of the V-shaped structure for the axle, and has a wide range of applicability to a certain extent.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
