Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of four-wheel alignment, in particular to an auxiliary assembly for four-wheel alignment adjustment. BACKGROUND

[0002] At present, the application of multi-link independent suspension structure in passenger cars is more and more, and the suspension structure theory can independently adjust the toe and camber of four-wheel alignment. Figure 1 The position indicated by the arrow is the camber adjustment eccentric bolt position of four-wheel alignment, and the inclination angle between the subframe assembly and the multi-link suspension upper swing arm assembly is determined by the eccentric bolt. The operation direction and operation area of the eccentric bolt for four-wheel alignment camber adjustment are indicated by the arrow. The multi-link suspension upper swing arm assembly is installed on the swing arm mounting bracket of the subframe assembly through the eccentric bolt. The swing arm mounting bracket is provided with a waist-shaped bolt hole, and the end face of the swing arm mounting bracket is provided with a clamping groove for fixing the eccentric washer. The eccentric washer is installed at both ends of the eccentric bolt, and the two eccentric washers are located in the clamping groove. When the eccentric bolt rotates, the two eccentric washers rotate synchronously with the bolt. The different positions of the eccentric washer abut against the inner wall of the clamping groove, so that the eccentric bolt is locked in different positions in the waist-shaped hole, thereby changing the angle between the multi-link suspension upper swing arm and the subframe assembly. During adjustment, the fixing nut needs to be loosened first, and then the eccentric bolt is rotated clockwise or counterclockwise by using a wrench, a ratchet and other tools to drive the rotation of the eccentric washer, so as to adjust the position of the bolt in the waist-shaped hole and achieve the purpose of four-wheel alignment camber adjustment. However, due to the limitation of the arrangement space, the operation space of the adjustment tools such as wrench and ratchet is insufficient. Moreover, due to the weight of the vehicle itself, the four-wheel alignment camber of the suspension will automatically return to the innermost position when the wrench and ratchet tools are loosened during small adjustment.

[0003] Due to the above reasons, many vehicles do not have camber adjustment design, or have camber adjustment function, but the adjustment is difficult or impossible. Therefore, it is necessary to improve the current four-wheel alignment adjustment structure. SUMMARY

[0005] The present application provides an auxiliary assembly for four-wheel alignment adjustment, comprising:

[0006] a support cover plate, wherein a through hole is arranged on the support cover plate;

[0007] a push column, wherein the push column slides along the through hole;

[0008] a push block, wherein the push block is fixed on the push column;

[0009] A variable diameter sleeve is sleeved on the push column, the variable diameter sleeve is located between the push block and the support cover plate, and the outer diameter of the variable diameter sleeve is different in size along the sliding direction of the push column;

[0010] A locking structure is used for locking the position of the push column in the through hole.

[0011] The auxiliary assembly of the application has the following beneficial effects: the variable diameter sleeve of the auxiliary assembly is arranged between the sub-frame assembly and the upper swing arm assembly of the multi-link suspension, the two sides of the variable diameter sleeve in the radial direction abut against the sub-frame assembly and the eccentric bolt respectively, when the push block pushes the variable diameter sleeve to change the position of the eccentric bolt, the position of the eccentric bolt is adjusted, the posture of the upper swing arm assembly of the multi-link suspension is adjusted, and the inclination angle of the wheel is adjusted, and since the position of the eccentric bolt is determined by the top holding and limiting of the variable diameter sleeve, the eccentric bolt cannot swing towards the recovery position, and the adjustment precision is high.

[0012] As some sub-schemes of the auxiliary assembly for four-wheel alignment adjustment, the outer periphery of the variable diameter sleeve is conical.

[0013] As some sub-schemes of the auxiliary assembly for four-wheel alignment adjustment, the locking structure comprises external threads and internal threads, one of the external threads and the internal threads is arranged on the support cover plate, and the other is arranged on the push column, and the external threads and the internal threads are threadedly connected.

[0014] As some sub-schemes of the auxiliary assembly for four-wheel alignment adjustment, the auxiliary assembly for four-wheel alignment adjustment further comprises a support nut, the support nut comprises the internal threads, the external threads are formed on the outer periphery of the push column, and the support cover plate is further provided with an avoiding hole in communication with the inner side of the support nut.

[0015] As some sub-schemes of the auxiliary assembly for four-wheel alignment adjustment, the push block is integrally formed with the push column.

[0016] As some sub-schemes of the auxiliary assembly for four-wheel alignment adjustment, the push block and the push column are a screw.

[0017] As some sub-schemes of the auxiliary assembly for four-wheel alignment adjustment, a gasket is further arranged between the push block and the variable diameter sleeve.

[0018] The application further provides a four-wheel alignment adjustment structure suitable for a multi-link suspension, comprising:

[0019] A sub-frame assembly is provided with an upper swing arm mounting bracket on one side, the upper swing arm mounting bracket is further provided with a gasket groove, and the bottom surface of the gasket groove is provided with a first connecting rod shaft hole.

[0020] A multi-link suspension upper control arm assembly, the multi-link suspension upper control arm assembly including a second link support shaft hole, one of the first link support shaft hole and the second link support shaft hole being an oblong hole;

[0021] An eccentric screw and a fixing nut are provided. The eccentric screw passes through the first connecting rod support hole and the second connecting rod support hole and is threadedly connected to the fixing nut. The head of the eccentric screw is provided with an eccentric washer, and one side of the eccentric washer abuts against the washer groove.

[0022] In the aforementioned auxiliary component for four-wheel alignment adjustment of the multi-link suspension, the push column is located between the eccentric shim and the subframe assembly, the support cover is located above the fixing nut, the push block is located below the fixing nut, and the eccentric shim or the fixing nut abuts against the outer circumferential surface of the variable diameter sleeve.

[0023] The beneficial effects of the present invention on a four-wheel alignment adjustment structure for multi-link suspension are as follows: In the four-wheel alignment adjustment structure for multi-link suspension of the present invention, the variable diameter sleeve abuts against the eccentric washer or the fixing nut, so that the position of the eccentric bolt will not retract under the action of gravity after being adjusted by the variable diameter sleeve. In addition, since the push block is located at the bottom, it can be adjusted from the bottom when the car is lifted, so as to make fine adjustment of the wheel camber angle, which is convenient.

[0025] The beneficial effects of the adjustment method for the multi-link suspension four-wheel alignment adjustment structure of the present invention are as follows: When adjusting, the position of the variable diameter sleeve along the push rod axis is changed, and the position of the eccentric shim is changed accordingly, thereby determining the wheel camber angle. Since the variable diameter sleeve restricts the position retraction of the eccentric bolt, compared with the prior art which requires a large rotational force to be applied to the eccentric bolt when adjusting the position of the eccentric shim, the precision of adjusting the wheel camber angle can be greatly improved, and the difficulty of adjusting the wheel camber angle can be reduced.

[0026] As a sub-scheme of the above adjustment method, in step S2, the eccentric bolt is also rotated at the same time. Attached Figure Description

[0048] The embodiments of the present application will be described below. Figures 1 to 9 The embodiments of the present application will be described below.

[0049] The present embodiment relates to a four-wheel alignment adjustment structure suitable for a multi-link suspension, which is used to adjust the inclination angle of a wheel connected by a swing arm assembly 2 and a subframe assembly 1 on a multi-link suspension.

[0050] At present, when the inclination angle of the wheels connected by the swing arm assembly 2 of the multi-link suspension is adjusted, after the vehicle is lifted by the lifting platform, the fixed nut 52 needs to be loosened by using a wrench, and then another wrench is used to adjust the rotation direction of the eccentric washer 36 by clamping the head of the eccentric screw 51 to change the inclination angle of the wheels. Since the force required for adjustment is large, it is very difficult to finely adjust the eccentric screw 51. In addition, after the inclination angle of the wheels is adjusted to the appropriate angle and before the eccentric lock is locked, it is difficult to stably keep the eccentric washer 36 from retreating. Furthermore, since the inclination angles of the four wheels need to be coordinated with each other when the inclination angle of the wheels is adjusted, multiple adjustments are required, and it is very difficult to accurately perform the four-wheel positioning operation.

[0051] The four-wheel positioning adjustment structure of the multi-link suspension of the embodiment comprises a sub-frame assembly 1, a multi-link suspension swing arm assembly 2, an eccentric screw 51, a fixed nut 52, and an auxiliary assembly for four-wheel positioning adjustment of the multi-link suspension.

[0052] One side of the sub-frame assembly 1 is provided with a swing arm mounting bracket 11, and the swing arm mounting bracket 11 is further provided with a washer groove, and the bottom surface of the washer groove is provided with a first connecting rod shaft hole;

[0053] The multi-link suspension swing arm assembly 2 comprises a second connecting rod shaft hole, and one of the first connecting rod shaft hole and the second connecting rod shaft hole is a waist-shaped hole;

[0054] The eccentric screw 51 is threadedly connected with the fixed nut 52 through the first connecting rod shaft hole and the second connecting rod shaft hole, the head of the eccentric screw 51 is provided with an eccentric washer 36, and one side of the eccentric washer 36 abuts against the washer groove;

[0055] The auxiliary assembly for four-wheel positioning adjustment of the multi-link suspension is used to limit the swing of the multi-link suspension swing arm assembly 2 towards the sub-frame assembly 1.

[0056] Specifically, the auxiliary assembly for four-wheel positioning adjustment comprises a support cover plate 31, a push column 32, a push block 34, and a variable-diameter sleeve 33. The support cover plate 31 is provided with a through hole; the push column 32 slides along the through hole; the push block 34 is fixed on the push column 32; the variable-diameter sleeve 33 is sleeved on the push column 32, and the variable-diameter sleeve 33 is located between the push block 34 and the support cover plate 31; the outer diameter of the variable-diameter sleeve 33 is different in size along the sliding direction of the push column 32; and the locking structure is used to lock the position of the push column 32 in the through hole.

[0057] The variable diameter sleeve 33 of the auxiliary assembly is arranged between the subframe assembly 1 and the multi-link suspension upper swing arm assembly 2, and the two sides of the variable diameter sleeve 33 in the radial direction are respectively in abutment with the subframe assembly 1 and the eccentric bolt. When the push rod 32 slides along the through hole, the push block 34 pushes the outer peripheral surface of the variable diameter sleeve 33 to change the position of the eccentric bolt in the waist-shaped hole. Specifically, in the embodiment, the outer peripheral surface of the variable diameter sleeve 33 is in abutment with the swing arm head 22 of the multi-link suspension upper swing arm assembly 2, so as to adjust the position of the eccentric bolt, change the posture of the multi-link suspension upper swing arm support, and adjust the inclination angle of the wheel. Since the position of the eccentric bolt is determined by the top holding and limiting of the variable diameter sleeve 33, the eccentric bolt cannot swing towards the recovery position, and the adjustment accuracy is high.

[0058] The outer peripheral surface of the variable diameter sleeve 33 is conical. When the outer peripheral surface of the variable diameter sleeve 33 is conical, the change of the outer diameter of the variable diameter sleeve 33 along the axial direction is constant, and it is easier and more accurate to adjust by pushing the variable diameter sleeve 33 through the push rod 32 and the push block 34.

[0059] The locking structure includes external threads and internal threads, one of which is arranged on the support cover plate 31, and the other of which is arranged on the push rod 32, and the external threads are threadedly connected with the internal threads. The locking structure is designed as internal threads and external threads, and the support cover plate 31 and the push rod 32 are threadedly connected through the internal threads and the external threads. By relatively rotating the push rod 32 through the threaded structure, the relative distance between the push block 34 on the push rod 32 and the support cover plate 31 can be changed, so as to complete the adjustment of the auxiliary assembly. After the adjustment is completed, the position can be fixed by the self-locking of the threaded structure. This structure can conveniently realize the adjustment and fixation of the position of the push block 34.

[0060] The support nut 35 includes the internal threads, and the external threads are formed on the outer peripheral surface of the push rod 32. The support cover plate 31 is further provided with an avoiding hole in communication with the inner side of the support nut 35. The support nut 35 includes the internal threads, and the external threads are formed on the outer peripheral surface of the push rod 32. The support nut 35 is arranged on the support cover plate 31, so that the push rod 32 is threadedly connected with the support nut 35. This can increase the connection length of the internal threads and the external threads, increase the structural strength, and improve the structural stability. In addition, the support nut 35 is a standard part, which is easy to obtain. The support nut 35 is connected with the support cover plate 31 in this form.

[0061] The push block 34 is integrally formed with the push rod 32. The structure that the push block 34 is integrally formed with the push rod 32 reduces the number of parts and reduces the assembly difficulty.

[0062] The push block 34 and the push rod 32 are a screw. The screw is a standard part, and the use of the screw as the push rod 32 and the push block 34 can reduce the cost.

[0063] The push block 34 and the variable diameter sleeve 33 are further provided with a gasket. The gasket arranged between the push block 34 and the variable diameter sleeve 33 can increase the contact area between the push block 34 and the variable diameter sleeve 33, reduce the pressure between the push block 34 and the variable diameter sleeve 33, and push the variable diameter sleeve 33 more stably. When the multi-link suspension four-wheel alignment adjusting assembly is used, the push column 32 is located between the eccentric gasket 36 and the auxiliary frame assembly 1, the support cover plate 31 is located above the fixed nut 52, the push block 34 is located below the fixed nut 52, and the eccentric gasket 36 or the fixed nut 52 abuts against the outer circumferential surface of the variable diameter sleeve 33.

[0064] The method for using the multi-link suspension four-wheel alignment adjusting structure comprises the following steps: S1, loosening the eccentric bolt; S2, adjusting the push block 34 along the axis of the push column 32 to a suitable position; and S3, locking the eccentric bolt again.

[0065] The adjusting method of the multi-link suspension four-wheel alignment adjusting structure has the following beneficial effects: when the adjusting method is used to adjust, the position of the eccentric gasket 36 changes after the position of the variable diameter sleeve 33 along the axis of the push column 32 is changed, and then the inclination angle of the wheel is determined. Since the variable diameter sleeve 33 limits the position backoff of the eccentric bolt, compared with the prior art, the adjusting method can greatly improve the fineness of adjusting the inclination angle of the wheel and reduce the difficulty of adjusting the inclination angle of the wheel.

[0066] In step S2, the eccentric bolt is also rotated. Adjusting the eccentric bolt at the same time can provide more adjustment space.

[0067] The preferred embodiments of the present application are described above, but the present application is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application, and these equivalent modifications or replacements are all included in the scope of the present application.
