Description

Technical Field

[0001] This invention relates to the field of off-highway mining dump truck technology, and more specifically, to an anti-collision component and an off-highway mining dump truck. Background Technology

[0002] Off-highway mining dump trucks experience bumps and vibrations during use. The rear suspension cylinder of the off-highway mining dump truck is connected between the chassis assembly and the rear axle assembly. Combining the compression and extension characteristics of the rear suspension cylinder, it absorbs the impact force from the road surface, thereby protecting the various structures of the off-highway mining dump truck and providing the driver with a comfortable driving experience.

[0003] However, when the road surface is bumpy and the safety distance between the frame assembly and the rear axle assembly is small, the rear suspension cylinder is easily subjected to rigid collisions between the frame assembly and the rear axle assembly, which may cause weld cracks in the rear suspension cylinder and lead to failure of the off-highway mining dump truck. Summary of the Invention

[0004] The main objective of this invention is to provide a collision avoidance component and an off-highway mining dump truck to solve the problem of malfunctions in off-highway mining dump trucks caused by rear suspension cylinder damage in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a collision avoidance assembly is provided, disposed between a vehicle frame assembly and a rear axle assembly. The collision avoidance assembly includes: a collision avoidance member and at least one collision avoidance post. At least a portion of the end face of the collision avoidance member is an arcuate surface, the arcuate surface of the collision avoidance member is used to abut against the vehicle frame assembly, the collision avoidance member is connected to the rear axle assembly, one axial end face of the collision avoidance post abuts against the vehicle frame assembly, and the collision avoidance post is movably inserted through the collision avoidance member along the axial direction of the collision avoidance post so that the other axial end face of the collision avoidance post abuts against the rear axle assembly.

[0006] Furthermore, the anti-collision components and anti-collision posts are fitted with a clearance.

[0007] Furthermore, the anti-collision component is provided with a through hole that extends along the axial direction of the anti-collision post, and the diameter of the through hole is larger than the diameter of the anti-collision post.

[0008] Furthermore, the anti-collision component includes an anti-collision body and a connecting part arranged sequentially along the depth direction of the anti-collision component. The connecting part is used to connect with the rear axle assembly. The anti-collision body includes a first anti-collision surface and a second anti-collision surface arranged opposite to each other along the depth direction of the anti-collision component. The first anti-collision surface is an arc-shaped surface and is used to abut against the vehicle frame assembly. The second anti-collision surface is used to connect with the connecting part. The depth direction of the anti-collision component is parallel to the axial direction of the anti-collision post.

[0009] Furthermore, from the radial direction of the through hole, from the circumferential edge of the first anti-collision surface to the central axis of the anti-collision member, the distance between the first anti-collision surface and the second anti-collision surface gradually increases along the depth direction of the anti-collision member.

[0010] Furthermore, a groove is provided on the connecting part, the groove is recessed in the direction of the depth of the anti-collision component toward the direction of the first anti-collision surface, the bottom surface of the groove is an arc surface, a protrusion is provided on the rear axle assembly, the groove and the protrusion are adapted to each other so that the protrusion is inserted into the groove so that the anti-collision component and the rear axle assembly are connected; wherein, there is a clearance gap between the protrusion and the bottom surface of the groove.

[0011] Furthermore, along the radial direction of the through hole, from the edge of the groove bottom surface to the central axis of the anti-collision member, the distance between the second anti-collision surface and the groove bottom surface gradually increases along the depth direction of the anti-collision member.

[0012] Furthermore, there are multiple crash barriers, which are spaced apart and inserted into the crash barrier components.

[0013] Furthermore, both the anti-collision components and the anti-collision posts are made of elastic materials.

[0014] According to another aspect of the present invention, an off-highway mining dump truck is provided, comprising a frame assembly, a rear axle assembly, a rear suspension cylinder assembly, and the aforementioned anti-collision components.

[0015] The present invention provides a collision avoidance assembly comprising a collision avoidance member and at least one collision avoidance post. At least a portion of the end face of the collision avoidance member is an arc-shaped surface. The collision avoidance member is connected to the rear axle assembly. By providing a collision avoidance post that is movably inserted through the collision avoidance member along its axial direction, when the chassis assembly moves toward the rear axle assembly, the chassis assembly will compress the collision avoidance post, causing the collision avoidance post to move to another axial end face that abuts against the rear axle assembly. At this time, the arc-shaped surface of the collision avoidance member abuts against the chassis assembly, so that the collision avoidance member and the collision avoidance post together prevent the chassis assembly from continuing to move toward the rear axle assembly. This ensures that there is a sufficient safety distance between the chassis assembly and the rear axle assembly, avoiding a safety distance that is too small, which would cause the rear suspension cylinder to be subjected to rigid collisions between the chassis assembly and the rear axle assembly. This solves the problem in the prior art where damage to the rear suspension cylinder leads to malfunctions in off-highway mining dump trucks. Attached Figure Description

[0025] Please refer to Figures 1 to 3 The present invention provides a collision avoidance assembly disposed between a frame assembly 200 and a rear axle assembly 300. The collision avoidance assembly includes a collision avoidance member 11 and at least one collision avoidance post 17. At least a portion of the end face of the collision avoidance member 11 is an arc-shaped surface, which is used to abut against the frame assembly 200. The collision avoidance member 11 is connected to the rear axle assembly 300. One axial end face of the collision avoidance post 17 abuts against the frame assembly 200. The collision avoidance post 17 is movably inserted through the collision avoidance member 11 along the axial direction of the collision avoidance post 17 so that the other axial end face of the collision avoidance post 17 abuts against the rear axle assembly 300.

[0026] The anti-collision assembly of the present invention includes an anti-collision member 11 and at least one anti-collision post 17. At least a portion of the end face of the anti-collision member 11 is arc-shaped. The anti-collision member 11 is connected to the rear axle assembly 300. The anti-collision post 17 is movably mounted on the anti-collision member 11 along its axial direction. When the frame assembly 200 moves toward the rear axle assembly 300, the frame assembly 200 will compress the anti-collision post 17, causing the anti-collision post 17 to move until its other axial end face is aligned with the rear axle assembly 300. When the anti-collision component 11 comes into contact with the frame assembly 200, the anti-collision component 11 and the anti-collision post 17 together prevent the frame assembly 200 from continuing to move towards the rear axle assembly 300. This ensures that there is a sufficient safety distance between the frame assembly 200 and the rear axle assembly 300, avoiding a situation where the safety distance is too small, causing the rear suspension cylinder to be subjected to a rigid collision between the frame assembly and the rear axle assembly. This solves the problem of off-highway mining dump trucks malfunctioning due to rear suspension cylinder damage in the prior art.

[0027] In this embodiment, the anti-collision member 11 and the anti-collision post 17 are clearance fit.

[0028] Specifically, this arrangement ensures that the anti-collision post 17 can move freely relative to the anti-collision member 11 along the axial direction of the anti-collision post 17, and ensures that the frame assembly 200 will press the anti-collision post 17 to move until the other axial end face of the anti-collision post 17 abuts against the rear axle assembly 300. This design allows the anti-collision component to absorb and disperse the collision impact force between the rear axle assembly 300 and the frame assembly 200 during vehicle operation.

[0029] In this embodiment, the anti-collision member 11 is provided with a through hole 131, which extends along the axial direction of the anti-collision post 17, and the diameter of the through hole 131 is larger than the diameter of the anti-collision post 17.

[0030] Specifically, this arrangement further ensures that the anti-collision post 17 can move freely relative to the anti-collision member 11 along the axial direction of the anti-collision post 17, avoiding the anti-collision post 17 and the anti-collision member 11 moving synchronously, which would prevent the anti-collision member 11 from buffering the frame assembly 200.

[0031] In this embodiment, the anti-collision member 11 includes an anti-collision body 14 and a connecting part 15 arranged sequentially along the depth direction of the anti-collision member 11. The connecting part 15 is used to connect with the rear axle assembly 300. The anti-collision body 14 includes a first anti-collision surface 12 and a second anti-collision surface 13 arranged opposite to each other along the depth direction of the anti-collision member 11. The first anti-collision surface 12 is an arc-shaped surface and is used to abut against the frame assembly 200. The second anti-collision surface 13 is used to connect with the connecting part 15. The depth direction of the anti-collision member 11 is parallel to the axial direction of the anti-collision post 17.

[0032] Specifically, by setting the first anti-collision surface 12 to abut against the frame assembly 200, the anti-collision component 11 can buffer the impact force applied by the frame assembly 200 to the rear axle assembly 300, effectively ensuring a sufficient safe distance between the frame assembly 200 and the rear axle assembly 300; by setting the second anti-collision surface 13 to connect with the connecting part 15, the reliable connection between the connecting part 15 and the anti-collision body 14 and the structural integrity of the anti-collision component 11 are ensured.

[0033] In this embodiment, the distance between the first anti-collision surface 12 and the second anti-collision surface 13 in the depth direction of the anti-collision member 11 gradually increases from the radial direction of the through hole 131, from the circumferential edge of the first anti-collision surface 12 to the central axis of the anti-collision member 11.

[0034] Specifically, this configuration allows the anti-collision component 11 to further disperse the impact force through the deformation of the first anti-collision surface 12 when it is impacted by the frame assembly 200, thereby enhancing the anti-collision flexibility and impact absorption capacity of the anti-collision component.

[0035] Specifically, the two ends of the crash barrier 17 are respectively inserted through the first crash barrier surface 12 and the second crash barrier surface 13.

[0036] In this embodiment, a groove 16 is provided on the connecting part 15. The groove 16 is recessed in the direction of the depth of the anti-collision member 11 toward the first anti-collision surface 12. The bottom surface of the groove 16 is an arc-shaped surface. A protrusion 301 is provided on the rear axle assembly 300. The groove 16 and the protrusion 301 are adapted to each other so that the protrusion 301 is inserted into the groove 16 so that the anti-collision member 11 and the rear axle assembly 300 are connected. There is a clearance gap between the protrusion 301 and the bottom surface of the groove 16.

[0037] Specifically, by providing a clearance gap between the protrusion 301 and the bottom surface of the groove 16, the anti-collision post 17 is allowed to undergo slight displacement relative to the anti-collision member 11 when it is squeezed by the frame assembly 200, thereby further improving the shock absorption effect of the anti-collision assembly; by inserting the protrusion 301 into the groove 16, a firm connection between the anti-collision member 11 and the rear axle assembly 300 is achieved.

[0038] In this embodiment, along the radial direction of the through hole 131, from the edge of the bottom surface of the groove 16 to the central axis of the anti-collision member 11, the distance between the second anti-collision surface 13 and the bottom surface of the groove 16 gradually increases along the depth direction of the anti-collision member 11.

[0039] Specifically, this design allows the anti-collision component 11 to further disperse the impact force when it is impacted by the frame assembly 200 through the deformation of the bottom surface of the groove 16, thereby enhancing the anti-collision flexibility and impact absorption capacity of the anti-collision component 11.

[0040] In this embodiment, there are multiple anti-collision posts 17, which are spaced apart and pass through the anti-collision member 11.

[0041] Specifically, by setting multiple anti-collision pillars 17, the impact force of the frame assembly 200 can be distributed more evenly, improving the anti-collision stability and reliability of the anti-collision components.

[0042] In this embodiment, both the anti-collision member 11 and the anti-collision post 17 are made of elastic material.

[0043] Specifically, the anti-collision components 11 and anti-collision posts 17, made of elastic materials, not only provide good impact absorption capabilities, but also significantly reduce the noise and vibration generated by the vehicle during operation. Especially in long-term, high-intensity mining transportation operations, this design can significantly improve the driver's working environment and driving comfort.

[0044] The present invention provides an off-highway mining dump truck, including a frame assembly 200, a rear axle assembly 300, a rear suspension cylinder assembly and the aforementioned anti-collision components.

[0045] The off-highway mining dump truck of the present invention includes a frame assembly 200, a rear axle assembly 300, a rear suspension cylinder assembly 400 and the aforementioned anti-collision components, wherein the rear suspension cylinder assembly 400 is disposed between the frame assembly 200 and the rear axle assembly 300.

[0046] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0047] The anti-collision assembly of the present invention includes an anti-collision member 11 and at least one anti-collision post 17. At least a portion of the end face of the anti-collision member 11 is arc-shaped. The anti-collision member 11 is connected to the rear axle assembly 300. The anti-collision post 17 is movably mounted on the anti-collision member 11 along its axial direction. When the frame assembly 200 moves toward the rear axle assembly 300, the frame assembly 200 will compress the anti-collision post 17, causing the anti-collision post 17 to move until its other axial end face is aligned with the rear axle assembly 300. When the anti-collision component 11 comes into contact with the frame assembly 200, the anti-collision component 11 and the anti-collision post 17 together prevent the frame assembly 200 from continuing to move towards the rear axle assembly 300. This ensures that there is a sufficient safety distance between the frame assembly 200 and the rear axle assembly 300, avoiding a situation where the safety distance is too small, causing the rear suspension cylinder to be subjected to a rigid collision between the frame assembly and the rear axle assembly. This solves the problem of off-highway mining dump trucks malfunctioning due to rear suspension cylinder damage in the prior art.

[0048] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
