Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to an interconnection system for two or more elastically suspended wheels of a new energy heavy-duty truck, and specifically to a stabilizer bar assembly for a new energy heavy-duty truck. Background Art

[0002] Stabilizer bar, also known as anti-roll bar, is mostly used in the suspension of automobile steering wheels. The stabilizer bar and the suspension rod are used to prevent and correct the roll that occurs during the steering process of the automobile front wheels. For example, a heavy-duty truck stabilizer bar assembly with announcement number CN211106834U in the prior art includes a pressure panel, a pressure block and a transmission rod, a connecting screw is provided in the middle of the pressure panel, and a pressure block is provided below the pressure panel, connecting blocks are provided on the left and right sides of the pressure block, and hinge buckles are provided inside the connecting blocks, suspension springs are provided below the left and right ends of the pressure panel, a cantilever is connected to the side of the connecting block away from the pressure block, an anti-roll bar is provided below the pressure block, and movable sleeves are provided at the left and right ends of the anti-roll bar, a connecting shaft is provided at the upper end of the transmission rod, and a mounting seat is provided below the support column. Compared with the existing common stabilizer bar assembly, the torsional internal torque generated by the elastic stabilizer bar of the heavy truck hinders the deformation of the suspension spring, thereby reducing the lateral tilt and lateral angular vibration of the vehicle body, thereby improving the driving stability of the vehicle;

[0003] Or a high-stress air suspension stabilizer bar for new energy heavy trucks with a publication number of CN117565617A in the prior art, which relates to the field of stabilizer bars, includes a stabilizer bar body, the end of the stabilizer bar body is provided with a connection portion connected to the axle, the outer wall of the stabilizer bar body is sleeved with a first connecting ring and a second connecting ring, and a limiting mechanism is provided on the stabilizer bar body. The invention sets a limiting mechanism, and by setting a limiting mechanism, when the first connecting ring and the second connecting ring are fixed to the preset position of the outer wall of the stabilizer bar by bolts, a downward pressure can be applied to the push rod at the preset position, so that the four movable blocks are moved out from the inside of the stabilizer bar body to the two ends of the first connecting ring and the second connecting ring, and the first connecting ring and the second connecting ring are limited to prevent the connecting ring from moving axially after loosening. Compared with the traditional limiting method, this structure can be self-adjusted according to the length of the connecting ring, further improving the connection force;

[0004] This type of stabilizer bar can play a good role in increasing the stability of the car's front wheels during movement, but there are still some shortcomings. Because the stabilizer bar needs to be connected to the bottom of the car chassis through bushings and splints, the stabilizer bar will repeatedly and frequently rub and squeeze the bushing during car turning and front wheel jumping. Moreover, since this type of heavy-duty new energy vehicle often travels on complex road environments, although its chassis is relatively high, it is easy for mud, sand, and garbage to adhere to the bushing, causing the bushing to wear easily and generate noise. The actual use effect needs to be further improved. Summary of the invention

[0011] Preferably, a liquid cooling zone is provided in the inner space of the assembly rod within the wrapping range of the bushing, and the coolant in the liquid cooling zone is connected to the conveying mechanism, and produces a conveying effect in the form of a car and promotes the circulation of the coolant in the liquid cooling zone.

[0012] Preferably, the conveying mechanism consists of a counterweight plate and a connecting pipe, the outer side of the counterweight plate is a liquid cooling zone that penetrates the reinforcement section and the assembly rod, wherein the one-way input end and the one-way output end of the liquid cooling zone are respectively connected to the top ends of the two connecting pipes, and the tail ends of the two connecting pipes are respectively connected to the one-way input end and the one-way output end of the liquid pot.

[0013] Preferably, the liquid pot is arranged on the back side of the assembly rod, and is connected to the assembly rod or the vehicle body.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 8, the present invention provides the following technical solutions:

[0030] Embodiment 1: In this embodiment, in order to solve the problems existing in the prior art, the following scheme is disclosed, including an assembly rod 1 and a reinforcement section 2 arranged in the middle of the assembly rod 1, wherein a reserved hole 3 for connecting with the suspension rod is arranged at the end of the assembly rod 1, and a bushing 5, a splint 6 wrapped outside the bushing 5, and a bracket 4 for connecting the splint 6 and the vehicle body are arranged on the surface of the assembly rod 1, and a cleaning mechanism is arranged on the side of the bushing 5, wherein the cleaning mechanism is installed on the assembly rod 1, and the cleaning mechanism generates power and cleans the surface of the bushing 5 by following the movement of the heavy truck through the assembly rod 1, and the cleaning mechanism includes a ring body 8 installed on the assembly rod 1 and an internal hollow structure of the ring body 8, the hollow structure is connected to a nozzle assembly 7 installed on the side of the ring body 8, wherein the air delivery section of the nozzle assembly 7 is a bellows, and the internal hollow structure of the ring body 8 is connected to the air supply mechanism, the air supply mechanism is arranged in the assembly rod 1, and follows the movement of the assembly rod 1 to generate airflow and transport it to the internal cavity of the ring body 8 through the air pipe 9, Figure 1-Figure 3 The solution shown is to add a ring body 8 structure to the stabilizer bar assembly of the metal rod. When the heavy truck turns, the nozzle assembly 7 in the assembly rod 1 will spray out airflow accordingly, and the source of the airflow is the air supply mechanism. The air supply mechanism can be an air pump or other equipment associated with the operation of the assembly rod 1. The air supply mechanism is associated with the air supply mechanism by a sensor that identifies the movement state of the assembly rod 1 or the vehicle. The airflow enters the air pipe 9 through the air supply mechanism, and further enters the internal cavity of the ring body 8 through the air pipe 9, and is finally sprayed toward the bushing 5 from the nozzle, thereby cleaning the garbage contaminated on the bushing 5 and avoiding accelerated damage to the bushing due to deflection and extrusion of the assembly in the bushing 5.

[0031] In this embodiment, an automatic and non-electrically driven automatic air supply solution is disclosed in detail. The advantages are low cost and reliable structure. The disadvantage is that the air flow intensity is relatively weak, but it can still play a cleaning effect, especially for garbage that has just been contaminated near the bushing 5 during the driving of heavy trucks in complex environments. Figure 4As shown, the air supply mechanism includes an air flow space arranged inside the reinforcement section 2 and a fan blade 10 arranged in the space, wherein the fan blade 10 is fixed to the inner end of the cross cylinder 11, and the outer end of the cross cylinder 11 is connected to a driving mechanism, and the driving mechanism generates a driving force through the turning of the vehicle to drive the cross cylinder 11 and the fan blade 10 to rotate to generate air flow, and the driving mechanism includes a cross bar 12 and a twisted rod fixedly connected to the cross bar 12 and threadedly installed inside the outer end of the cross cylinder 11, wherein the middle section of the cross bar 12 is horizontally elastically slidably installed inside the reinforcement section 2 through a spring, and the cross bar 1 The outer end of 2 is connected to the counterweight plate 13. During the driving of the heavy truck, especially during turning, the inertia force and the centrifugal force will cause the counterweight plate 13 to slide inside the reinforcement section 2, and the cross bar 12 directly connected to the counterweight plate 13 will slide inside the reinforcement section 2 synchronously. Due to the thread transmission effect, the thread transmission between the twisted rod at the inner end of the cross bar 12 and the cross cylinder 11 will convert the horizontal movement force of the cross bar 12 into the rotation driving force of the cross cylinder 11, so the fan blades 10 will also rotate synchronously and generate airflow and transport it to the air pipe 9, thereby realizing the effect of automatic air supply.

[0032] Embodiment 2: When a vehicle is driving, especially a heavy truck driving on a complex road, the front wheels will face a more severe working environment, and the surface of the stabilizer bar assembly as a stabilizer will repeatedly rub against the inner wall of the bushing 5. Due to high temperature and high frequency friction, the service life of the bushing 5 will be greatly reduced. Therefore, in order to solve this problem, this embodiment also discloses the following solution, which adopts Figure 6 In the liquid cooling scheme shown, a liquid cooling zone 15 is provided in the inner space of the assembly rod 1 within the wrapping range of the bushing 5, and the coolant in the liquid cooling zone 15 is connected to the conveying mechanism, and produces a conveying effect through the form of the automobile and promotes the circulation of the coolant in the liquid cooling zone 15. During the driving process of the automobile, especially during the turning process, the coolant can circulate in the liquid cooling zone 15, thereby quickly cooling the area wrapped by the bushing 5 and reducing the increase in loss caused by excessive temperature.

[0033] The solution disclosed in this embodiment is similar to the above solution, and also adopts a non-electric drive mechanism. The non-electric drive in this solution is mainly reflected in the circulation of the coolant in the liquid cooling area 15, such as Figure 6As shown, the conveying mechanism consists of a counterweight plate 13 and a connecting pipe 14, and the outer side of the counterweight plate 13 is a liquid cooling zone 15 that penetrates the reinforcement section 2 and the assembly rod 1, wherein the one-way input end and the one-way output end of the liquid cooling zone 15 are respectively connected to the top ends of the two connecting pipes 14, and the tail ends of the two connecting pipes 14 are respectively connected to the one-way input end and the one-way output end of the liquid pot 16; the liquid pot 16 is arranged on the back side of the assembly rod 1, which is connected to the assembly rod 1 or the vehicle body, and when the counterweight plate 13 is in the process of reciprocating movement, the internal space of the liquid cooling zone 15 outside it will also be compressed or stretched accordingly, so its internal volume and pressure reciprocating changes will guide the coolant in the liquid pot 16 to circulate in the liquid cooling zone 15 under the connection of the connecting pipe 14, thereby achieving the effect of automatically circulating the coolant.

[0034] In this embodiment, another solution is disclosed, which has the effect of preventing the high-intensity work of the tire and the suspension from causing the area wrapped by the bushing 5 to be in a high temperature state due to repeated bounce of the tire when the heavy truck is driving on a long straight line or a road with insufficient steering. Figure 7 and Figure 8 As shown, a pressure plate 17 including a buoyancy member 18 is further provided inside the liquid pot 16. The pressure plate 17 is vertically elastically slidably installed in the liquid pot 16 by a spring, and the liquid pot 16 is also vertically distributed. The lower part of the pressure plate 17 is the coolant storage space. When the counterweight plate 13 moves actively, the pressure plate 17 will rise and fall due to the influence of buoyancy to match the volume change of the coolant in the liquid pot 16. When the tire is in a state of frequent jumping and insufficient steering or no steering, the pressure plate 17 itself will actively move up and down due to the inertial force. In this process, the coolant in the liquid pot 16 will actively circulate in the liquid cooling area 15 through the connecting pipe 14, wherein Figure 8 The solid arrow in the middle indicates the liquid flow direction when the pressure plate 17 moves downward, and the dotted arrow indicates the liquid flow direction when the pressure plate 17 moves upward. At the same time, the counterweight plate 13 is driven to passively reciprocate, and the movement of the counterweight plate 13 can also drive the fan blades 10 to rotate and generate airflow, thereby increasing the effect of air cooling and impurity removal.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
