Description

Technical Field

[0001] This utility model belongs to the field of new energy engineering vehicle technology, and more specifically, it relates to a wide-body vehicle oil-gas suspension structure and vehicle. Background Technology

[0002] With the rapid development of new energy vehicles and the requirements for green mining construction, the demand and market scope of electric wide-body vehicles are expanding, and the requirements for their power and range are increasing. To meet these requirements, it is necessary to increase the number of batteries, resulting in larger battery packs and powertrains, more wiring harnesses, and consequently, increasingly limited space within the vehicle frame.

[0003] To improve vehicle lifespan and prevent stress concentration in the chassis, a crossbeam and its connection are typically incorporated to ensure even lateral tension is transmitted to the chassis. In existing technology, the crossbeam is located beneath the chassis, with a mounting bracket at its top. This mounting bracket, situated inside the chassis, serves as an intermediate connection between the crossbeam and the chassis. However, this placement restricts internal chassis space, reducing the clearance between the mounting bracket and the powertrain, resulting in insufficient mounting space for the powertrain wiring harness. Utility Model Content

[0004] The purpose of this utility model is to provide a wide-body vehicle hydropneumatic suspension structure and vehicle, which aims to solve the problem in the prior art where the transverse push beam is connected to the frame through a mounting bracket located inside the frame, which occupies the space inside the frame and reduces the space between the mounting bracket and the powertrain, resulting in insufficient installation space for the powertrain wiring harness.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] Firstly, a wide-body vehicle hydropneumatic suspension structure is provided, comprising:

[0007] A suspension cylinder support for connecting to a vehicle frame, the suspension cylinder support including a first connecting portion and a second connecting portion distributed at an included angle, the first connecting portion being located on the outer side of the vehicle frame, and the second connecting portion being located on the bottom of the vehicle frame; and

[0008] A lateral push beam, located at the bottom of the frame and connected to the second connection, has a hinged position for connecting a lateral tie rod.

[0009] In conjunction with the first aspect, in one possible implementation, the suspension cylinder support includes:

[0010] A mounting bracket for connection to a vehicle frame, the mounting bracket including a first mounting plate and a second mounting plate connected to the bottom of the first mounting plate, the first mounting plate forming a first connecting portion, and the second mounting plate forming a second connecting portion; and

[0011] Mounting lugs are attached to the outside of the first mounting plate to provide mounting positions for the lifting device.

[0012] In conjunction with the first aspect, in one possible implementation, the mounting bracket further includes a reinforcing plate connected to the top of the first mounting plate, the reinforcing plate being used for connection to the top of the vehicle frame.

[0013] In conjunction with the first aspect, in one possible implementation, the mounting lug includes a fixing portion connected to the first mounting plate and a reinforcing portion connected to the reinforcing plate, the fixing portion being used to provide a mounting position for the lifting device.

[0014] In conjunction with the first aspect, in one possible implementation, the transverse pusher beam includes:

[0015] Support member, connected to the first connecting portion; and

[0016] A fastener, connected to the bottom of the support member, is used to provide a hinge position for the transverse tie rod.

[0017] In conjunction with the first aspect, in one possible implementation, multiple fasteners are provided along the front-rear direction, and a receiving space for accommodating a transverse tie rod is formed between two adjacent fasteners.

[0018] In conjunction with the first aspect, in one possible implementation, the support member includes a support portion and mounting flanges symmetrically arranged on both sides of the support portion in a left-right direction. The support portion has a "U" shaped structure, and the mounting flanges are connected to the second connecting portion. The horizontal push beam also includes a reinforcing plate connected to the mounting flanges and the support portion. The two ends of the reinforcing plate abut against the mounting flanges and the support portion, respectively, and the reinforcing plate is also connected to the fixing member.

[0019] In conjunction with the first aspect, in one possible implementation, the fastener has a first mounting hole corresponding to a second mounting hole on the transverse tie rod, and the transverse push beam further includes a reinforcing plate connected to the fastener, the reinforcing plate having a clearance hole corresponding to the first mounting hole, the reinforcing plate being used to increase the local strength of the fastener.

[0020] In conjunction with the first aspect, in one possible implementation, the support portion includes a support plate and connecting plates disposed on both sides of the support plate in a left-right direction, the connecting plates being disposed at an angle to the support plate, and the transverse push beam further includes an abutment plate, the abutment plate being connected to the connecting plate and the support plate respectively.

[0021] The beneficial effects of the wide-body vehicle hydropneumatic suspension structure provided by this utility model are as follows: Compared with the prior art, the cylinder support is set on the outside of the frame, and both the first and second connecting parts of the cylinder support are connected to the frame. Since the second connecting part is connected to the bottom of the frame, it serves as an intermediate medium to connect the push beam to the frame. This utility model eliminates the need for mounting brackets on the inside of the frame to connect the push beam to the frame, reducing intermediate connecting parts, saving costs, and also reducing the space occupied on the inside of the frame, providing more installation space for the powertrain and allowing the powertrain wiring harness to be organized. In addition, since the push beam is connected to the bottom of the second connecting part, compared with the prior art where the push beam needs to be connected to a mounting bracket located on the inside of the frame, the longitudinal distance between the lateral tie rod mounting position and the push beam fixing surface is reduced, thereby reducing the stress on the push beam fixing surface. The first and second connecting parts of the suspension cylinder support are both connected to the frame, which not only provides a mounting position for the push beam, but also increases the contact area with the frame and improves the connection strength with the frame.

[0022] Secondly, this utility model embodiment also provides a vehicle, including the wide-body vehicle hydropneumatic suspension structure described above.

[0023] The beneficial effects of the vehicle provided by this utility model are as follows: compared with the prior art, it adopts the above-mentioned wide-body vehicle hydropneumatic suspension structure, which has similar technical effects to the above-mentioned wide-body vehicle hydropneumatic suspension structure, and will not be described in detail here.

[0031] Please refer to the following: Figures 1 to 3The present invention will now describe the wide-body vehicle hydropneumatic suspension structure and the vehicle itself. The wide-body vehicle hydropneumatic suspension structure includes a cylinder support 1 and a push beam 2. The cylinder support 1 is used to connect to the vehicle frame and includes a first connecting part and a second connecting part distributed at an angle. The first connecting part is located on the outside of the vehicle frame, and the second connecting part is located on the bottom of the vehicle frame. The push beam 2 is located at the bottom of the vehicle frame and is connected to the second connecting part. The push beam 2 has a hinge position for connecting a lateral tie rod.

[0032] The wide-body vehicle hydropneumatic suspension structure provided by this utility model, compared with the prior art, places the cylinder support 1 on the outside of the vehicle frame, and both the first and second connecting parts of the cylinder support 1 are connected to the vehicle frame. Since the second connecting part is connected to the bottom of the vehicle frame, it serves as an intermediate medium to connect the push beam 2 to the vehicle frame. This utility model eliminates the need for mounting brackets on the inside of the vehicle frame to connect the push beam 2, reducing intermediate connecting components, saving costs, and also reducing the space occupied on the inside of the vehicle frame, providing more installation space for the powertrain and allowing for better organization of the powertrain wiring harness. Furthermore, since the push beam 2 is connected to the bottom of the second connecting part, compared to the prior art where the push beam 2 needs to be connected to a mounting bracket located on the inside of the vehicle frame, the longitudinal distance between the lateral tie rod mounting position and the fixed surface of the push beam 2 is reduced, thereby reducing the stress on the fixed surface of the push beam 2. The first and second connecting parts of the cylinder support 1 are both connected to the frame, which not only provides a mounting position for the push beam 2, but also increases the contact area with the frame and improves the connection strength with the frame.

[0033] In some embodiments, please refer to Figure 1 and Figure 3 The suspension cylinder support 1 includes a mounting bracket 101 and a mounting lug 102. The mounting bracket 101 is used to connect to the vehicle frame. The mounting bracket 101 includes a first mounting plate 1011 and a second mounting plate 1012 connected to the bottom of the first mounting plate 1011. The first mounting plate 1011 forms a first connecting portion, and the second mounting plate 1012 forms a second connecting portion. The mounting lug 102 is connected to the outside of the first mounting plate 1011 and is used to provide a mounting position for the lifting device.

[0034] Mounting lug 102 is connected to the outside of the first mounting plate 1011 to avoid interference with the frame and to provide a mounting position for the lifting device. In this embodiment, both the first mounting plate 1011 and the second mounting plate 1012 are connected to the frame, increasing the connection area with the frame. This provides a fixing surface for the crossbeam 2 and also increases the reliability of the connection.

[0035] Optionally, the mounting bracket 101 is an integral component, and the mounting bracket 101 and the mounting lug 102 are integrally formed or welded together.

[0036] Optionally, the mounting lug 102 has a fixing hole, which forms a mounting position.

[0037] Optionally, the mounting lug 102 is also provided with a reinforcing rib, which is also connected to the first mounting plate 1011 to improve the strength of the mounting lug 102.

[0038] In some embodiments, please refer to Figure 3 The mounting bracket 101 also includes a reinforcing plate 1013 connected to the top of the first mounting plate 1011, the reinforcing plate 1013 being used to connect to the top of the frame.

[0039] In this embodiment, the reinforcing plate 1013 not only improves the strength of the mounting bracket 101, but also further increases the contact area with the vehicle frame, ensuring the firmness and reliability of the connection between the mounting bracket 101 and the vehicle frame.

[0040] Specifically, the reinforcing plate 1013, the first mounting plate 1011, and the second mounting plate 1012 form a "U" shaped structure.

[0041] In some embodiments, please refer to Figure 3 The mounting lug 102 includes a fixing part 1022 connected to the first mounting plate 1011 and a reinforcing part 1021 connected to the reinforcing plate 1013. The fixing part 1022 is used to provide a mounting position for the lifting device.

[0042] In this embodiment, the fixing part 1022 is connected to the first mounting plate 1011, and the reinforcing part 1021 is connected to the reinforcing plate 1013, thereby increasing the contact area between the mounting lug 102 and the mounting frame 101 and improving the connection stability between the mounting lug 102 and the mounting frame 101. After the lifting device is connected to the fixing part 1022, the probability of the reinforcing part 1021 deforming and being damaged due to force or separating from the mounting frame 101 can be reduced.

[0043] In some embodiments, please refer to Figure 1 The transverse push beam 2 includes a support member 201 and a fixing member 202. The support member 201 is connected to the first connecting part; the fixing member 202 is connected to the bottom of the support member 201 and is used to provide a hinge position for the transverse tie rod.

[0044] Support member 201 is connected to the bottom of the first connecting part, increasing the contact area with the first connecting part. Fixing member 202 is connected to the bottom of support member 201, providing a hinge position for the lateral tie rod, ensuring that the lateral tie rod can be effectively connected to fixing member 202, while avoiding interference with the frame or the second connecting part.

[0045] Optionally, the fastener 202 is a symmetrical component with the vertical direction as the axis of symmetry.

[0046] In some embodiments, please refer to Figure 1Multiple fasteners 202 are provided along the front-to-back direction, and a receiving space for accommodating the transverse tie rod is formed between two adjacent fasteners 202.

[0047] Setting multiple fasteners 202 can increase the overall strength of the transverse push beam 2. The transverse tie rod is located between two adjacent fasteners 202 to avoid interference with other components in the vehicle and to achieve a rational layout of the interior space.

[0048] In some embodiments, please refer to Figure 1 and Figure 2 The support member 201 includes a support part and mounting flanges 2011 symmetrically arranged on both sides of the support part in the left-right direction. The support part has a "U" shaped structure. The mounting flanges 2011 are connected to the second connecting part. The horizontal push beam 2 also includes a reinforcing plate 204 connected to the mounting flanges 2011 and the support part. The two ends of the reinforcing plate 204 abut against the mounting flanges 2011 and the support part, respectively. The reinforcing plate 204 is also connected to the fixing member 202.

[0049] In this embodiment, the support portion has a "U"-shaped structure. This not only provides clearance for the powertrain by recessing the support portion downwards, but also increases its own strength and resistance to deformation. The mounting flange 2011 connects to the second connecting portion, increasing the contact area and improving the stability and firmness of the connection. The two ends of the reinforcing plate 204 abut against the mounting flange 2011 and the reinforcing plate 204 respectively, improving the relative stability of the mounting flange 2011 and the support portion and preventing changes in the angle between them under stress. Furthermore, the reinforcing plate 204 is also connected to the fastener 202, further enhancing its stability.

[0050] Optionally, the support component 201 is an integral structure, which has higher strength than the welding solution.

[0051] In some embodiments, please refer to Figure 1 and Figure 3 The fastener 202 has a first mounting hole, which corresponds to the second mounting hole on the transverse tie rod. The transverse push beam 2 also includes a reinforcing plate 203 connected to the fastener 202. The reinforcing plate 203 has a clearance hole corresponding to the first mounting hole. The reinforcing plate 203 is used to increase the local strength of the fastener 202.

[0052] Since the first mounting hole is opened on the fastener 202, the strength of the area around the first mounting hole of the fastener 202 will be reduced. Setting a reinforcement part here can increase the strength and deformation resistance of this area, and avoid the problem of deformation of the area around the first mounting hole due to stress after the transverse tie rod is connected to the fastener 202.

[0053] Optionally, the reinforcing plate 203 may be welded or riveted to the fastener 202.

[0054] In some embodiments, please refer to Figure 3 The support part includes a support plate 2012 and a connecting plate 2013 disposed on both sides of the support plate 2012 in the left and right direction. The connecting plate 2013 is set at an angle to the support plate 2012. The horizontal push beam 2 also includes an abutment plate 205, which is connected to the connecting plate 2013 and the support plate 2012 respectively.

[0055] The abutment plate 205 is connected to the connecting plate 2013 and the support plate 2012 respectively, thereby ensuring that the positions of the connecting plate 2013 and the support plate 2012 are relatively stable and improving the deformation resistance of the support plate 2012 and the connecting plate 2013.

[0056] Optionally, the included angle between the support plate 2012 and the connecting plate 2013 is an obtuse angle.

[0057] Based on the same inventive concept, this utility model also provides a vehicle. The vehicle includes the aforementioned wide-body vehicle hydropneumatic suspension structure.

[0058] The vehicle provided by this utility model adopts the aforementioned wide-body vehicle hydropneumatic suspension structure, with the cylinder bearing 1 located on the outer side of the frame, and both the first and second connecting parts of the cylinder bearing 1 connected to the frame. Since the second connecting part is connected to the bottom of the frame, it serves as an intermediate medium to connect the push beam 2 to the frame. This utility model eliminates the need for an internal mounting bracket to connect the push beam 2 to the frame, reducing intermediate connecting components, saving costs, and minimizing the space occupied on the inner side of the frame. This provides more installation space for the powertrain, allowing for better organization of the powertrain wiring harness. Furthermore, since the push beam 2 is connected to the bottom of the second connecting part, compared to the prior art where the push beam 2 needs to be connected to a mounting bracket located on the inner side of the frame, the longitudinal distance between the lateral tie rod mounting position and the fixed surface of the push beam 2 is reduced, thereby reducing the stress on the fixed surface of the push beam 2. The first and second connecting parts of the cylinder support 1 are both connected to the frame, which not only provides a mounting position for the push beam 2, but also increases the contact area with the frame and improves the connection strength with the frame.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
