Detailed Description

For purposes of making the objects, technical solutions, and advantages of the present disclosure more apparent, the principle and spirit of the present disclosure will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are presented merely to enable one skilled in the art to better understand and practice the present disclosure and are not intended to limit the scope of the present disclosure in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In this document, it should be understood that any number of elements in the drawings is for illustration and not limitation, and that any naming is used only for distinction and not for any limitation.

The principles and spirit of the present disclosure are explained in detail below with reference to several representative embodiments thereof.

Referring to fig. 1, there is provided a partial structure schematic diagram of a vehicle in the related art according to an exemplary embodiment of the present disclosure.

In the related art vehicle 100, an arm structure 102 and a vehicle body structure 104 are connected by an eccentric bolt 106.

Wherein, since the length of the arm body structure 102 itself is fixed, when the four-wheel angle of the vehicle 100 needs to be adjusted, the positional relationship between the arm body structure 102 and the vehicle body structure 104 is adjusted by adjusting the eccentric bolt 106, thereby achieving the adjustment of the four-wheel angle of the vehicle 100.

However, a large tool movement space is usually reserved at the eccentric bolt to facilitate adjustment of the eccentric bolt, thus resulting in a large space occupation of such an arm structure; meanwhile, the strength of the eccentric bolt is lower than that of a common bolt, and the safety coefficient is lower when the eccentric bolt encounters large-amplitude vibration; in addition, the cost of the eccentric bolt is higher than that of the common bolt.

Referring to fig. 2, a schematic structural view of a vehicle arm body according to an exemplary embodiment of the present disclosure is provided.

The vehicle arm body 200 includes:

an adjustment mechanism 202 and two arm bodies 204;

two of the arm bodies 204 are connected by the adjusting mechanism 202;

the arm body 204 is configured to be connected to a vehicle body mechanism (not shown);

the adjustment mechanism 202 is configured to adjust a distance between two of the arm body main bodies 204.

In some exemplary embodiments, the arm body 204 has a mounting hole 2042 provided therein;

the fitting hole 2042 is configured to be connected to the vehicle body mechanism.

In some exemplary embodiments, the mounting hole 2042 is a through hole through the arm body 204.

In some exemplary embodiments, the arm body 204 is threadably coupled to the body mechanism via the mounting hole 2042, i.e., the arm body 204 and the body mechanism are coupled by bolts passing through the mounting hole 2042.

In some exemplary embodiments, the vehicle body mechanism includes a subframe (not shown) and a knuckle assembly (not shown);

two of the arm bodies 204 are configured to be connected to one of the sub-frames and the other to the knuckle assembly.

In some exemplary embodiments, the adjusting mechanism 202 adjusts the distance between the two arm bodies 204 by changing its length, for example, the adjusting mechanism 202 adopts a telescopic rod structure;

in some exemplary embodiments, the adjustment mechanism 202 may be configured to adjust the distance between the two arm bodies 204 by varying the length of the adjustment mechanism that extends into the arm bodies 204, e.g., the adjustment mechanism 202 may be configured as a screw.

In the present disclosure, the distance between the two arm bodies 204 may be adjusted by the adjusting mechanism 202 to adjust the positional relationship between the sub-frame and the knuckle assembly to which the two arm bodies 204 are respectively connected, thereby achieving adjustment of the four-wheel angle of the vehicle. Because the arm body in the disclosure is composed of two arm body main bodies 204 with changeable distance, which is equivalent to that the whole arm body can change its own length, the utility model does not need to rely on eccentric bolts like the related art, and adopts common bolts, thereby not needing to reserve larger tool moving space and occupying smaller space; meanwhile, the strength of the common bolt is higher than that of the eccentric bolt, and the safety coefficient is higher when the common bolt encounters large-amplitude vibration; in addition, the cost of the common bolt is lower than that of the eccentric bolt.

Referring to fig. 3, a schematic diagram of an adjustment mechanism 202 provided in accordance with an exemplary embodiment of the present disclosure is shown.

In some exemplary embodiments, the adjustment mechanism 202 includes:

a screw 2022;

a screwing part 2024 is arranged in the middle of the screw 2022, and screw threads 2026 are arranged at two ends of the screw 2022;

the screw 2026 is configured to be connected to the arm body 204.

In some exemplary embodiments, the screw 2024 comprises:

a first nut;

the first nut is fixedly connected with the middle part of the screw 2022.

Wherein, since no relative displacement is generated between the first nut and the screw 2022, processes such as bonding, welding, integral forging, integral casting, etc. can be adopted.

Wherein, by screwing the first nut, the screw 2022 is rotated (screwed in or out of the arm body 204) to adjust the positional relationship between the adjusting mechanism 202 and the arm body 204.

In the above embodiments, the screwing portion 2024 is exemplified as a nut structure, and in some exemplary embodiments, the screwing portion 2024 may be other structures as long as it can be implemented for screwing.

In some exemplary embodiments, the adjustment mechanism 202 further comprises:

two second nuts 2028;

the second nut 2028 is screwed to the threaded portion 2026; wherein two of the second nuts 2028 are connected to two of the screw portions 2026, respectively.

Wherein, the second nut 2028 is configured to limit the adjusting mechanism 202 and the arm body 204 when the adjusting mechanism 202 and the arm body 204 are connected by the screw portion 2026, and to help the adjusting mechanism 202 and the arm body 204 maintain the adjusted positional relationship.

Wherein, the screw 2022 provided with the screw portion 2026 and the screw of the arm body 204 cooperate with each other to have a certain self-locking capability, and the second nut 2028 is used for further enhancing the fastening effect thereof.

Wherein, when adjusting, the second nut 2028 is unscrewed, then the adjusting mechanism 202 is turned to adjust the positional relationship between the adjusting mechanism 202 and the arm body 204, and after the adjustment is completed, the second nut 2028 is screwed.

In the related art, the position relation between the wheel and the frame is regulated through the eccentric bolt, and is limited by the structure of the eccentric bolt, so that the adjustable position relation range is limited;

in the present disclosure, however, the distance between the two arm bodies 204 can be adjusted by the adjusting mechanism 202 to adjust the positional relationship between the wheels and the frame to which the two arm bodies 204 are respectively connected, wherein the range of the adjustable positional relationship depends on the length of the screw 2022, and thus, as long as the length of the screw 2022 is long enough, the range of the adjustable positional relationship is large, that is, the range of the adjustable positional relationship is not limited.

Referring to fig. 4, a schematic diagram of an arm body 204 according to an exemplary embodiment of the present disclosure is provided.

In some exemplary embodiments, the arm body 204 is further provided with a bolt hole 2044, and an axial direction of the bolt hole 2044 is perpendicular to an axial direction of the assembly hole 2042;

the adjustment mechanism 202 and the arm body main body 204 are screwed together by the screw portion 2026 and the bolt hole 2044.

Wherein the distance between the two arm bodies 204 is adjusted by the extent to which the screw portion 2026 protrudes into the bolt hole 2044.

In some exemplary embodiments, a bushing 2046 is disposed within the mounting hole 2042; the bushing 2046 is rotatably coupled to the mounting hole 2042.

Wherein the bushing 2046 is configured to reduce wear of the mounting hole 2042.

In some exemplary embodiments, both ends of the bushing 2046 protrude out of the fitting hole 2042.

In some exemplary embodiments, the arm body 204 further has a relief hole 2048 disposed thereon;

wherein the assembly hole 2042 is provided on the arm body 204 on a side thereof remote from the adjustment mechanism 202; the relief holes 2048 are provided on the arm body 204 on a side thereof adjacent to the adjustment mechanism 202.

Wherein the lightening holes 2048 are configured to reduce the weight and cost of the arm body 204 while ensuring that the rigidity and strength of the arm body 204 can meet the requirements.

As can be seen from the above, the vehicle arm body provided in the embodiment of the present disclosure includes: the adjusting mechanism and the two arm body main bodies; the two arm body main bodies are connected through the adjusting mechanism; the arm body is configured to be connected with a vehicle body mechanism; the adjusting mechanism is configured to adjust a distance between the two arm bodies. According to the vehicle arm body, the distance between the two arm body main bodies is adjusted through the adjusting mechanism, so that the position relation between the two arm body main body connected vehicle body mechanisms can be adjusted, no additional mechanism components are needed to be relied on, no additional space is occupied, and the reliability is high.
