Description

Technical Field

[0001] The present invention belongs to the technical field of automobile components, and more particularly, relates to a front axle separator structure and an automobile. Background Art

[0002] The front axle decoupler, located at the outer end of the front axle half-shaft sleeve, connects the front axle half-shaft to the mechanical wheel. It is an inter-axle clutch device that switches the vehicle between two-wheel drive and four-wheel drive. It enables the vehicle to switch between two-wheel drive and four-wheel drive by controlling the motor via a switch, which drives the gears to rotate and connect and disconnect the front axle half-shaft to the mechanical wheel via a connecting sleeve. In two-wheel drive mode, the disconnection of the front axle half-shaft from the mechanical wheel causes the main gear, differential housing, and front axle drive shaft inside the front reducer to remain stationary, eliminating the energy consumption associated with the rotation of these components and improving the vehicle's fuel economy.

[0003] Existing front axle decouplers simply use a motor to mechanically move the coupling sleeve left and right, connecting and disconnecting the front axle half-shaft and the mechanical wheel to achieve two-wheel drive switching. However, in many cases, the front axle half-shaft splines are misaligned with the mechanical wheel splines, causing the mechanical wheel splines to block the coupling sleeve, preventing the coupling sleeve from moving to the right and thus preventing connection. Drivers, unaware of the specific situation, may repeatedly press the decoupler switch, causing the motor inside the decoupler to continuously operate, resulting in motor burnout or damage to the front axle decoupler. Summary of the Invention

[0004] The purpose of the present invention is to provide a front axle separator structure, which aims to solve the problem that the splines of the front axle half-shaft and the splines of the mechanical wheel are not aligned, the splines of the mechanical wheel will block the connecting sleeve, the connecting sleeve cannot move to the right, and the connection cannot be achieved. Repeatedly pressing the switch of the separator will cause the motor inside the separator to keep moving, resulting in motor burnout or damage to the front axle separator.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a front axle separator structure, comprising:

[0006] A separator housing, wherein a driving member and a moving member are provided in the separator housing, and the driving member drives the moving member to move;

[0007] A connecting member, used to connect the front axle half shaft and the mechanical wheel, one end of the connecting member is sleeved on the front axle half shaft, and the other end is connected to the moving member;

[0008] The adjusting member is used to rotate the connecting member, one end of the adjusting member is rotatably connected to the connecting member, and the other end is slidably connected to the moving member.

[0009] In a possible implementation, the connecting member includes:

[0010] a shift fork, one end of which is connected to the moving member; and

[0011] A connecting sleeve is connected to the other end of the shift fork, and an internal spline is provided on the inner wall of the connecting sleeve. The connecting sleeve is used to connect the front axle half shaft alone, or to connect the front axle half shaft and the mechanical wheel at the same time with the help of the internal spline. The adjusting member is used to rotate the connecting sleeve.

[0012] In a possible implementation, a first gear is provided at one end of the adjusting member, and a second gear that can mesh with the first gear is provided on the circumference of the connecting sleeve near the front axle half shaft.

[0013] In a possible implementation, a first spline is provided on the circumference of the outer wall of the adjusting member, and a second spline that cooperates with the first spline is provided on the outer side wall of the moving member along its axial direction.

[0014] In a possible implementation, the second spline has a length of 18-22 mm and a width of 8-10 mm.

[0015] In a possible implementation, the second spline is located on a side of the moving member close to the connecting member, and an end of the second spline is flush with one side of the shift fork.

[0016] In a possible implementation, the adjusting member is provided with a rotating shaft, and the rotating shaft is fixed to the separator housing.

[0017] In a possible implementation, the diameter of the adjusting member is 8-10 mm.

[0018] The beneficial effect of the front axle separator structure provided by the present invention is that, compared with the prior art, during the switching process from the two-wheel drive state to the four-wheel drive state, the driving member drives the moving member to move toward the side of the mechanical wheel. If the front axle half-shaft spline is not aligned with the mechanical wheel spline, the connecting member returns to its original position after encountering resistance. At this time, the adjusting member rotates the connecting member, and the connecting member drives the front axle half-shaft to rotate so that the front axle half-shaft spline is aligned with the mechanical wheel spline. As a result, the next time the connecting member moves toward the mechanical wheel, the connecting member is smoothly sleeved on the mechanical wheel, and the front axle half-shaft and the mechanical wheel are connected, so as to achieve the purpose of switching from two-wheel drive to four-wheel drive. The front axle separator structure provided by the present invention can avoid the problem of motor burnout or front axle separator damage caused by repeatedly pressing the separator switch when the front axle half-shaft spline is not aligned with the mechanical wheel spline.

[0019] The present invention also provides an automobile comprising the front axle separator structure.

[0020] Compared with the prior art, the automobile provided by the present invention has the same beneficial effects as the prior art due to the use of the front axle decoupler structure. This can prevent the problem of motor burnout or front axle decoupler damage caused by repeated activation of the decoupler switch when the front axle half-shaft splines are misaligned with the mechanical wheel splines.

DETAILED DESCRIPTION

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] See also Figures 1 to 6 The front axle decoupler structure provided by the present invention is now described. The front axle decoupler structure includes a decoupler housing 100, a driving member, a moving member 400, a connecting member 500, and an adjusting member 600.

[0032] A driving member and a moving member 400 are provided in the separator housing 100, and the driving member drives the moving member 400 to move; the connecting member 500 is used to connect the front axle half shaft 200 and the mechanical wheel 300, one end of the connecting member 500 is sleeved on the front axle half shaft 200, and the other end is connected to the moving member 400; the adjusting member 600 is used to rotate the connecting member 500, one end of the adjusting member 600 is rotatably connected to the connecting member 500, and the other end is slidably connected to the moving member 400.

[0033] Compared to the prior art, the front axle decoupler structure provided by the present invention is characterized by a drive element driving the movable element 400 toward the mechanical wheel 300 during the transition from two-wheel drive to four-wheel drive. If the splines of the front axle half-shaft 200 and the mechanical wheel 300 are misaligned, the connector 500 encounters resistance and returns to its original position. At this point, the adjustment element 600 rotates the connector 500, which in turn drives the front axle half-shaft 200 to rotate, aligning the splines of the front axle half-shaft 200 with the splines of the mechanical wheel 300. This ensures that the next time the connector 500 moves toward the mechanical wheel 300, it smoothly fits over the mechanical wheel 300, connecting the front axle half-shaft 200 and the mechanical wheel 300, thereby achieving the switch from two-wheel drive to four-wheel drive. The front axle decoupler structure provided by the present invention can prevent the problem of motor burnout or front axle decoupler damage caused by repeatedly pressing the decoupler switch when the splines of the front axle half-shaft 200 and the mechanical wheel 300 are misaligned. Specifically, the moving member 400 is a connecting shaft arranged horizontally in the separator housing 100, and the driving member is a driving motor that can drive the connecting shaft to move back and forth horizontally; the upper part of the adjusting member 600 slides with the connecting shaft to realize the axial rotation of the adjusting shaft.

[0034] See also Figure 3 and Figure 6 The shift fork 510 includes an upper mounting sleeve and two legs fixedly connected to the lower portion of the mounting sleeve. The two legs are symmetrically arranged and integrally formed with the mounting sleeve. In addition, a connecting plate is integrally formed between the two legs to increase the strength of the two legs.

[0035] The legs consist of a connecting arm and a clamping arm connected sequentially from top to bottom. The connecting plate is located between the two connecting arms, and the clamping arm is the free end of the lower portion of the shift fork 510. An arcuate slot 523 is defined in the middle of the outer wall of the connecting sleeve 520. The two free ends of the shift fork 510 are respectively retained in the arcuate slots 523 and located on either side of the connecting sleeve 520.

[0036] Specifically, the width of the clamping arm is smaller than the width of the connecting arm, so that the clamping arm can smoothly enter the arc-shaped slot 523.

[0037] The mounting sleeve is fixed to the moving member 400 and is clamped within the arc-shaped slot 523 by the clamping arms at the bottom of the two legs, located on both sides of the connecting sleeve 520, thereby firmly clamping the connecting sleeve 520. The shift fork 510 can drive the connecting sleeve 520 to move along its axial direction, allowing the connecting sleeve 520 to connect solely to the front axle half-shaft 200 or simultaneously connect the front axle half-shaft 200 and the mechanical wheel 300.

[0038] See also Figure 1 and Figure 2 When the moving member 400 drives the connecting member 500 to approach the adjusting member 600, the first gear 610 and the second gear 522 engage with each other, and the connecting sleeve 520 can rotate relative to the fork 510, thereby driving the front axle half shaft 200 to rotate so that it is aligned with the spline on the mechanical wheel 300.

[0039] Preferably, both the first gear 610 and the second gear 522 are bevel gears, which can provide a more stable transmission effect. Specifically, when the first gear 610 and the second gear 522 are engaged with each other, a worm gear structure can be formed. That is, the adjusting member 600 forms a worm structure with the first gear 610 at its lower end, and the connecting sleeve 520 forms a worm gear structure with the second gear 522 at one side.

[0040] See also Figure 2 and Figure 4 The end of the second spline 410 is flush with one side of the upper end of the fork 510, which can limit the distance that the moving member 400 drives the fork 510 to move closer to the front axle half shaft 200. When the first spline 620 on the adjusting member 600 drives the adjusting shaft to rotate through the second spline 410 engaged with it, until the adjusting member 600 is close to the fork 510, the first gear 610 and the second gear 522 are just in a meshing state.

[0041] See also Figure 5 The rotating shaft 630 is rotatably mounted on the upper end of the adjusting member 600 and is coaxial with the adjusting member 600. The upper end of the rotating shaft 630 is fixed to the separator housing 100. The rotating shaft 630 enables the adjusting member 600 to rotate relative to the separator housing 100.

[0042] Specifically, the second spline 410 has a length of 18-22 mm and a width of 8-10 mm. Preferably, the second spline 410 has a length of 20 mm and a width of 9 mm.

[0043] Specifically, the adjusting member 600 is a longitudinally arranged adjusting shaft, and the diameter of the adjusting shaft is 8-10 mm. Preferably, the diameter of the adjusting shaft is 8 mm.

[0044] Preferably, the sizes of the second spline 410 and the adjusting shaft can be adapted to the sizes of standard vehicle parts, ensuring the matching accuracy and facilitating assembly and disassembly.

[0045] The front axle separator structure provided by the present invention has the following specific working process:

[0046] The driving member drives the movable member 400 to move toward the side of the mechanical wheel 300. The movable member 400 drives the connecting sleeve 520 to be simultaneously mounted on the front axle half-shaft 200 and the mechanical wheel 300. The internal splines 521 on the circumferential inner wall of the connecting sleeve 520 respectively cooperate with the splines on the front axle half-shaft 200 and the mechanical wheel 300. At this time, the front axle half-shaft 200 and the mechanical wheel 300 are connected by means of the connecting sleeve 520, and the entire vehicle is in a four-wheel drive state.

[0047] The driving member drives the moving member 400 to move toward the side of the front axle half-shaft 200. The moving member 400 drives the connecting sleeve 520 to be separately mounted on the front axle half-shaft 200 and separated from the mechanical wheel 300. The internal splines 521 on the circumferential inner wall of the connecting sleeve 520 respectively cooperate with the splines on the front axle half-shaft 200. At this time, the front axle half-shaft 200 is no longer connected to the mechanical wheel 300, and the entire vehicle is in a two-wheel drive state.

[0048] During the switching process from the two-wheel drive state to the four-wheel drive state, the driving component drives the moving part 400 to move toward the side of the mechanical wheel 300. If the spline of the front axle half shaft 200 is not aligned with the spline of the mechanical wheel 300, the connecting sleeve 520 returns to its original position after encountering resistance. At this time, the first gear 610 at the lower end of the adjusting part 600 is engaged with the second gear 522 on one side of the connecting sleeve 520. The moving part 400 drives the adjusting part 600 to rotate through the cooperation of the first spline 620 and the second spline 410, thereby driving the first gear 610 at the lower end of the adjusting part 600 to rotate. 10 rotates, and with the help of the first gear 610 and the second gear 522 that are meshed with each other, the connecting sleeve 520 also rotates slightly accordingly. The connecting sleeve 520 drives the front axle half shaft 200 to rotate through the internal spline 521, so that the splines of the front axle half shaft 200 are aligned with the splines of the mechanical wheel 300, so that the next time the connecting sleeve 520 moves toward the mechanical wheel 300, the connecting sleeve 520 can be smoothly sleeved on the mechanical wheel 300, thereby realizing the connection between the front axle half shaft 200 and the mechanical wheel 300, so as to achieve the purpose of switching from two-wheel drive to four-wheel drive.

[0049] The present invention also provides a car using the above-mentioned front axle separator structure.

[0050] Compared to the prior art, the automobile provided by the present invention utilizes the front axle decoupler structure, thereby achieving the same beneficial effects as the prior art. This prevents the problem of motor burnout or front axle decoupler damage caused by repeated activation of the decoupler switch when the splines of the front axle half-shaft 200 and the splines of the mechanical wheel 300 are misaligned.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
