Description

Technical Field

[0001] The present invention relates to the technical field of vehicle swing arms, and in particular to a swing arm assembly installation system and method. Background Art

[0002] The vehicle swing arm unit is an important part of the suspension system, which can effectively support the vehicle body and shock absorber to ensure the stability and integrity of the vehicle structure. The vehicle swing arm unit usually connects the wheel and the body elastically through the bushing unit to achieve relative movement between the wheel and the body and transmit various forces. As a connecting medium between the vehicle swing arm unit and other parts of the vehicle, the bushing unit can effectively reduce the wear of the swing arm unit and extend its service life. The bushing unit has a certain elasticity and can absorb and disperse the vibration and impact from the road surface during the vehicle driving, thereby reducing the vibration and noise inside the vehicle. The bushing unit plays a guiding role between the swing arm unit and other parts of the vehicle, ensuring that the swing arm unit can follow the predetermined trajectory during movement to avoid offset or dislocation, thereby ensuring accurate positioning of the wheel and ensuring the driving stability of the vehicle.

[0003] The connecting rod module and the outer jacket module of the bushing unit are usually fixedly connected as a whole through an elastic module. During the pressing process of pressing the bushing unit into the set position of the swing arm unit, the connecting rod module is squeezed by the pressing head, causing the outer jacket module to slide in the swing arm unit, and the outer jacket module squeezes the elastic module, which can easily cause a large deformation of the elastic module and cause damage to the elastic module during the pressing process. The damaged bushing unit may aggravate the wear of the swing arm unit when it continues to be used. Damage to the bushing unit will also increase maintenance costs and reduce the press-fitting efficiency of the bushing unit. Summary of the invention

[0042] The vehicle swing arm unit 11 usually elastically connects the wheel and the body through the bushing unit 12 to achieve relative movement between the wheel and the body and transmit various forces. In the process of pressing the bushing unit 12 into the set position of the swing arm unit 11, the pressing head squeezes the connecting rod module 121, causing the jacket module 123 to slide in the swing arm unit 11, and the jacket module 123 squeezes the elastic module 122, which easily causes a large deformation of the elastic module 122 and causes damage to the elastic module 122 during the pressing process. Damage to the bushing unit 12 will also increase maintenance costs and reduce the press-fitting efficiency of the bushing unit 12. In order to solve the problem that the elastic module 122 is easily damaged during the press-fitting process of the bushing unit 12, a swing arm assembly 01 installation system is proposed. Figure 1As shown, the installation system of the swing arm assembly 01 may include a base assembly 02, a positioning assembly 03, a pressing assembly 04, and the swing arm assembly 01. The base assembly 02 is used to support the entire installation system of the swing arm assembly 01. The positioning assembly 03 is used to fix the swing arm assembly 01 so that it is accurately positioned at the installation position.

[0043] The positioning assembly 03 can be detachably connected to the base assembly 02, which is convenient for installation. The positioning assembly 03 can be separately disassembled and replaced during maintenance. The pressing assembly 04 can include a pressing unit 41 and at least two half-ring units 42. The pressing unit 41 can include a pressing module 411 and a third driving unit 412. The third driving unit 412 can drive the pressing module 411 to press the bushing unit 12. The pressing module 411 can include a first pressing ring 4111, a second pressing ring 4113, and a limiting ring 4115. The first pressing ring 4111, the second pressing ring 4113, and the limiting ring 4115 can be fixedly connected in sequence, and can be a whole without a gap at the connection, thereby improving the structural strength of the pressing module 411. The inner diameter of the limiting ring 4115 can be larger than the outer contour arc diameter of the half-ring unit 42. In this way, the limiting ring 4115 can limit the half-ring unit 42 to a certain extent to prevent the half-ring unit 42 from deflecting or falling out.

[0044] like Figure 6 As shown, the swing arm assembly 01 may include a swing arm unit 11 and a bushing unit 12. Figure 4 As shown, the swing arm unit 11 may include an arm body 111 and a first sleeve 112. The arm body 111 and the first sleeve 112 may be fixedly connected. The first sleeve 112 may be used for installing the bushing unit 12. Figure 5As shown, the bushing unit 12 may include a connecting rod module 121, an elastic module 122, and a jacket module 123. The connecting rod module 121 may be used to connect the bushing unit 12 with other mechanical parts of the vehicle. The elastic module 122 is used for shock absorption and buffering in the bushing unit 12. The jacket module 123 can effectively protect the connecting rod module 121 and the elastic module 122 inside the bushing unit 12 from damage by the external environment. The connecting rod module 121 may include a connecting rod body 1211 and a positioning ring 1212. The positioning ring 1212 may be sleeved on the outer peripheral side of the connecting rod body 1211. The positioning ring 1212 may be fixedly connected to the connecting rod body 1211. Part of the connecting rod body 1211 may be arranged in the through hole of the jacket module 123, and the positioning ring 1212 may be arranged outside the through hole of the jacket module 123, thereby ensuring the correct positioning of the connecting rod module 121 in the jacket module 123. At least two half ring units 42 can be arranged between the positioning ring 1212 and the outer coat module 123, so that the positioning ring 1212 can conduct the pressed force received to the outer coat module 123 through the half ring unit 42, thereby reducing the force of the elastic module 122. The connecting rod module 121 can be arranged at intervals with the outer coat module 123, and at least part of the elastic module 122 can be arranged between the connecting rod module 121 and the outer coat module 123, so that the elastic module 122 can have enough space to play its shock absorption and buffering effect. At least part of the inner peripheral wall of the elastic module 122 can be fixedly connected with the connecting rod module 121, and this connection mode ensures that the elastic module 122 can be closely fitted on the connecting rod module 121 and move with it. The elastic module 122 can absorb and disperse the impact and vibration from the connecting rod module 121. The outer peripheral wall of at least part of the elastic module 122 can be fixedly connected with the outer coat module 123, so that the elastic module 122 is firmly installed in the outer coat module 123 in this way to prevent it from falling off during movement.

[0045] The installation system of the swing arm assembly 01 may also include a first pressing state. The first pressing state may include the swing arm unit 11 abutting against the positioning assembly 03, that is, the positioning assembly 03 fixes the swing arm unit 11 to a position where it can be correctly installed. At least two half-ring units 42 may be arranged between the positioning ring 1212 and the outer jacket module 123, whereby the pressure of the second pressure ring 4113 squeezing the positioning ring 1212 may be transmitted to the outer jacket module 123 through the half-ring unit 42, thereby reducing the force on the elastic module 122 and avoiding damage caused by a large deformation of the elastic module 122.

[0046] In some embodiments, since the elastic module 122 is integrally formed with the outer cover module 123 and the connecting rod module 121 by vulcanization molding, the elastic module 122 can be made of elastic materials such as rubber. The rubber raw material can be injected into the mold by an integral molding process, and then the rubber is vulcanized and molded. In order to facilitate demolding, a draft angle is designed on both sides of the mold cavity. This draft angle helps the elastic module 122 to be smoothly removed from the mold after molding, while avoiding scratching the surface of the elastic module 122 or causing deformation of the elastic module 122. Fig.11 As shown, the cross-sectional area of ​​the semi-ring unit 42 can be reduced from the outer ring wall of the semi-ring unit 42 to the inner ring wall thereof. In this way, in combination with the draft angle, the pressure of the second pressing ring 4113 squeezing the positioning ring 1212 can be better transmitted to the outer shell module 123 through the semi-ring unit 42, and the semi-ring unit 42 can be removed later.

[0047] In some embodiments, Fig.10 As shown, the semi-ring unit 42 may include a first semi-ring body 421 and a second semi-ring body 422. The first semi-ring body 421 and the second semi-ring body 422 may both be semicircular. The inner peripheral wall of the first semi-ring body 421 and the outer peripheral wall of the second semi-ring body 422 may be fixedly connected. The first semi-ring body 421 and the second semi-ring body 422 may be connected firmly and may withstand a certain pressure. The two planes where the two sides of the first semi-ring body 421 are located may be parallel, so that the first semi-ring body 421 cross section is rectangular, so that the pressure of the second pressure ring 4113 squeezing the positioning ring 1212 is conducted to the outer jacket module 123 through the semi-ring unit 42, and the force area of ​​the outer jacket module 123 is larger, so that the outer jacket module 123 is more uniformly stressed to avoid damage. The cross-sectional area of ​​the second semi-ring body 422 may be reduced from the outer peripheral wall of the second semi-ring body 422 toward the direction close to its inner peripheral wall. The second semi-ring body 422 may be wedge-shaped, and the cross-sectional area may be gradually reduced, so that the semi-ring unit 42 is easily installed between the positioning ring 1212 and the outer jacket module 123. The first pressed state may also include a side surface of the first semi-ring body 421 abutting against one end of the outer jacket module 123. In this way, the pressure of the second pressing ring 4113 squeezing the positioning ring 1212 can be better transmitted to the outer jacket module 123 through the semi-ring unit 42, thereby reducing the stress on the elastic module 122 and avoiding damage to the elastic module 122 due to large deformation.

[0048] In some embodiments, one side of the second semi-ring body 422 can extend obliquely toward the direction close to the other side thereof, and one side of the second semi-ring body 422 can overlap with the plane where one side of the first semi-ring body 421 away from the outer coat module 123 is located. The first pressed state can also include that one side of the second semi-ring body 422 away from the outer coat module 123 abuts against the elastic module 122 adjacent to one side of the positioning ring 1212, and one side of the second semi-ring body 422 extending obliquely can abut against the elastic module 122 adjacent to one side of the outer coat module 123. When the positioning ring 1212 is subjected to pressure, the semi-ring unit 42 and the positioning ring 1212 abutment are flat, so that the pressure can be transmitted to the elastic module 122, and the elastic module 122 can absorb part of the impact force and generate a reaction force, and the semi-ring unit 42 is more tightly locked between the positioning ring 1212 and the outer coat module 123 to avoid the semi-ring unit 42 from coming out during squeezing.

[0049] In some embodiments, Fig.13 As shown, R1 can be the inner ring radius of the second semi-ring body 422, R2 can be the inner ring radius of the first semi-ring body 421 or the outer ring radius of the second semi-ring body 422, and R3 can be the outer ring radius of the first semi-ring body 421. R2-R1 can be greater than R3-R2. In this way, the contact area between the side of the semi-ring unit 42 away from the positioning ring 1212 and the elastic module 122 is increased, thereby reducing the pressure acting on the elastic module 122, thereby avoiding damage to the elastic module 122 due to a large deformation.

[0050] In some embodiments, Figure 2 As shown, the first pressed state may also include that the symmetric center planes of the two half-ring units 42 are perpendicular to the arm body 111 of the swing arm unit 11. The presence of a gap between the two half-ring units 42 will lead to uneven pressing force on the side close to the arm body 111. By making the symmetric center planes of the two half-ring units 42 perpendicular to the arm body 111 of the swing arm unit 11, the influence of the gap between the two half-ring units 42 can be reduced, so that the pressing force on the side close to the arm body 111 is more uniform, and the displacement of the bushing unit 12 caused by the weight of the arm body 111 fixed on one side of the base assembly 02 can be avoided.

[0051] In some embodiments, the pressing module 411 may also include a third pressing ring 4114. The outer peripheral wall of the third pressing ring 4114 may be fixedly connected to a part of the inner peripheral wall of the limiting ring 4115. One side of the third pressing ring 4114 may be fixedly connected to a side of the second pressing ring 4113 away from the first pressing ring 4111. The first pressing state may also include a side of the third pressing ring 4114 away from the second pressing ring 4113 at least abutting against a side of a part of the semi-ring unit 42 close to the positioning ring 1212. In this way, the semi-ring unit 42 is squeezed by the third pressing ring 4114 to squeeze the side of one end close to its outer contour, so as to avoid the semi-ring unit 42 from tilting up during the squeezing process of the semi-ring unit 42 when the positioning ring 1212 is subjected to the pressure of the second pressing ring 4113, so that the pressure is better transmitted to the jacket module 123 through the semi-ring unit 42. At the same time, the third pressing ring 4114 also generates pressure on the half-ring unit 42, so as to press the half-ring unit 42 together with the second pressing ring 4113 to transmit the pressure to the jacket module 123, thereby improving the press-fitting efficiency of the bushing unit 12.

[0052] In some embodiments, Fig.12 As shown, A can be the minimum distance between the side of the third pressure ring 4114 away from the second pressure ring 4113 and the side of the second pressure ring 4113 away from the first pressure ring 4111, and B can be the minimum distance between the side of the semi-ring unit 42 close to the positioning ring 1212 and the side of the positioning ring 1212 away from the semi-ring unit 42. A can be less than or equal to B. As a result, the side of the positioning ring 1212 away from the semi-ring unit 42 can be stressed first, and when the elastic module 122 between the semi-ring unit 42 and the side of the positioning ring 1212 close to the semi-ring unit 42 is compressed, the semi-ring unit 42 is subjected to pressure, so that the force on the semi-ring unit 42 is less than the pressure on the side of the positioning ring 1212 away from the semi-ring unit 42, so as to avoid the semi-ring unit 42 from tilting, so that the pressure of the second pressure ring 4113 squeezing the positioning ring 1212 is mainly transmitted to the sleeve ring 1232 of the outer cover module 123 through the semi-ring unit 42. Avoid damage to the elastic module 122 by directly pressing the semi-ring unit 42. The force on the half ring unit 42 is smaller than the pressure on the side of the positioning ring 1212 away from the half ring unit 42, thereby preventing the half ring unit 42 from falling off between the positioning ring 1212 and the outer cover module 123 due to uneven force.

[0053] In other embodiments, the swing arm unit 11 may further include a second sleeve 113, and the arm body 111 may be fixedly connected to the second sleeve 113, and the second sleeve 113 may be used to fix the arm body 111. The elastic module 122 may include a connector 1221, a first elastic ring 1222, a second elastic ring 1223, and an elastic groove 1224. The connector 1221 may be fixedly connected to the first elastic ring 1222 and the second elastic ring 1223. The stability and reliability of the entire elastic module 122 during operation are ensured. The elastic groove 1224 may be used to enhance the elasticity and flexibility of the elastic module 122, and to facilitate heat dissipation and lubrication. The outer sleeve module 123 may include a sleeve 1231 and a collar 1232. The sleeve 1231 and the collar 1232 may be fixedly connected. Figure 8 As shown, the positioning assembly 03 may include a first positioning unit 31, a second positioning unit 32, and a detection unit 33. The detection unit 33 may detect the state of the swing arm unit 11 to determine the installation of the bushing unit 12. Figure 3 As shown, the first positioning unit 31 may include a first positioning seat 311, a first positioning rod 312, and a first driving portion 313. The first positioning seat 311 may be detachably connected to the first positioning rod 312, and the first positioning rod 312 may be drivingly connected to the first driving portion 313. Fixing the position of the swing arm unit 11 in this way helps to press-fit the bushing unit 12. The second positioning unit 32 may include a second positioning seat 321, a second positioning rod 322, a positioning rod body 3221, a first positioning groove 3222, and a second driving portion 323. Figure 7 As shown, the second positioning seat 321 can be detachably connected to the second positioning rod 322, and the second positioning rod 322 can be drivingly connected to the second driving part 323. The first positioning groove 3222 can be used to provide a positioning reference to ensure positioning accuracy. This method is used to fix the position of the swing arm unit 11 to facilitate the press-fitting of the bushing unit 12. Fig. 9 As shown, the pressing module 411 may further include a second positioning groove 4112 for positioning. The second positioning groove 4112 may ensure the position accuracy of the pressing module 411 during the pressing process.

[0054] In this embodiment, a method for installing a swing arm assembly 01 is disclosed, such as Fig.14 As shown, it may include step S10 to step S30, and each step is described in detail as follows:

[0055] Step S10, when the swing arm unit 11 is positioned and fixed on the positioning assembly 03, to prevent the swing arm unit 11 from shaking during the pressing process, the half ring unit 42 can be placed between the positioning ring 1212 and the jacket module 123 to facilitate the pressing module 411 to perform pressing.

[0056] Step S20, when the half ring unit 42 is placed between the positioning ring 1212 and the outer shell module 123, the swing arm assembly 01 installation system can enter the first pressing state. The first pressing state can include the swing arm unit 11 abutting against the positioning assembly 03, at least two half ring units 42 can be arranged between the positioning ring 1212 and the outer shell module 123, and the pressure of the second pressing ring 4113 squeezing the positioning ring 1212 can be transmitted to the outer shell module 123 through the half ring unit 42. Thus, the pressure of the second pressing ring 4113 squeezing the positioning ring 1212 can be transmitted to the outer shell module 123 through the half ring unit 42, thereby reducing the force on the elastic module 122 and avoiding damage caused by a large deformation of the elastic module 122.

[0057] Step S30, when the installation system of the swing arm assembly 01 enters the first pressing state, the pressing module 411 can press the bushing unit 12 into the installation position of the swing arm unit 11. The installation position can include the outer peripheral wall of the jacket module 123 of the bushing unit 12 abutting against the inner peripheral wall of the first sleeve 112, one side of the half ring unit 42 abutting against the positioning ring 1212, and the other side of the half ring unit 42 abutting against the elastic module 122 and the jacket module 123 respectively. In this way, it can be ensured that the bushing unit 12 is pressed into the correct position without being skewed, and the pressure of the second pressing ring 4113 squeezing the positioning ring 1212 can be transmitted to the jacket module 123 through the half ring unit 42, thereby reducing the force on the elastic module 122 and avoiding damage caused by large deformation of the elastic module 122.

[0058] In some embodiments, the first pressed state in step S20 can also include that the symmetrical center plane of the two half-ring units 42 is perpendicular to the arm body 111 of the swing arm unit 11, so that the pressing force on the side close to the swing arm unit 11 can be more uniform, and the swing arm unit 11 can be prevented from being offset by the press-fitting of the bushing unit 12 due to the influence of the weight of the swing arm unit 11 fixed on one side of the base assembly 02. One side of the first half-ring body 421 can abut against one end of the coat module 123. One side of the first half-ring body 421 away from the coat module 123 at least abuts against part of the third pressing ring 4114. One side of the second half-ring body 422 away from the coat module 123 abuts against the elastic module 122 adjacent to one side of the positioning ring 1212. One side of the second half-ring body 422 obliquely extending can abut against the elastic module 122 adjacent to one side of the coat module 123. When the positioning ring 1212 is subjected to pressure, the half-ring unit 42 and the positioning ring 1212 are in flat contact with each other, so that the pressure will be transmitted to the elastic module 122. The elastic module 122 will absorb part of the impact force and generate a reaction force, locking the half-ring unit 42 more tightly between the positioning ring 1212 and the outer sleeve module 123 to prevent the half-ring unit 42 from falling out when squeezed.

[0059] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and in actual applications, various changes may be made thereto in form and detail without departing from the scope of the present disclosure.
