Description

Technical Field

[0001] This utility model particularly relates to a device for correcting the deformation of an automotive torsion beam. Background Technology

[0002] In common automotive rear axle structures, the torsion beam serves as a monolithic support frame, with half-shafts connected to both ends. These half-shafts are then connected to the differential and wheel hubs via universal joints, transmitting power and supporting the wheels. Because the torsion beam bears complex loads during vehicle operation, prolonged use or external impacts (such as bumps, bottoming out, welding deformation, etc.) can cause it to bend, twist, or shift in its installation position, affecting the alignment accuracy between the half-shafts, differential, and wheel hubs. This deviation can lead to vehicle vibration, uneven tire wear, abnormal bearing wear, and even transmission system malfunctions. Currently, correcting torsion beam deformation mainly relies on manual experience, such as using pry bars, hydraulic jacks, or manually tapping after heating with a flame. These methods are not only inefficient and inaccurate but can also cause secondary damage due to improper force application. Utility Model Content

[0030] The transmission mechanism can apply tension or thrust to change the relative position of the first fixed frame 1 and the second fixed frame 2, thereby causing the torsion beam 1-1 to bend and deform.

[0031] Furthermore, the transmission mechanism is a hydraulic cylinder 31, whose cylinder body 311 is fixed on the second fixed frame 2, and the piston end 312 acts on the first fixed frame 1, applying a thrust to the first fixed frame 1 through the piston end 312.

[0032] Furthermore, the transmission mechanism is an electric hoist 41, with both ends of the electric hoist 41 fixed on the first fixed frame 1 and the second fixed frame 2 respectively. The electric hoist 41 drives the first fixed frame 1 and the second fixed frame 2 to move relative to each other.

[0036] Furthermore, the first fixing frame 1 is provided with a force transmission area 10 for receiving and transmitting the force applied by the piston end 312.

[0037] The working principle of this utility model is as follows:

[0038] As an example of embodiment 1, the transmission mechanism is illustrated using an electric hoist 41 as an example to illustrate the design concept of this application. The first fixed frame 1 and the second fixed frame 2 are respectively fixed to both ends of the torsion beam 1-1, such as... Figure 1-2As shown, the fixed end of the electric hoist 41 is hung on the hanging part 412 on the second fixing frame 2, and the movable end of the electric hoist 41 is hung on the traction connection part 411 on the first fixing frame 1. The electric hoist 41 is started, and its movable end winds the chain, so that the first fixing frame 1 is displaced toward the second fixing frame 2 by the traction force transmitted through the chain; the relative displacement between the first fixing frame 1 and the second fixing frame 2 forces the torsion beam 1-1 to deform so as to realize correction, as Figure 1 shown, which is a schematic diagram of the deformed state of the torsion beam 1-1, Figure 1 is a schematic diagram of the state of the torsion beam 1-1 after being corrected by embodiment 1 of the present application.

[0039] As embodiment 2, the transmission mechanism takes the hydraulic cylinder 31 as an example to illustrate the design concept of the present application. The first fixing frame 1 and the second fixing frame 2 are respectively fixed at both ends of the torsion beam 1-1, as Figure 3 shown, the cylinder body 311 is fixed on the second fixing frame 2, and the piston end 312 acts on the first fixing frame 1. The hydraulic cylinder 31 is started, and a thrust is applied to the first fixing frame 1 through the piston end 312, so that the first fixing frame 1 and the second fixing frame 2 generate relative displacement, and the relative displacement deforms the torsion beam 1-1 to realize correction. As Figure 3 shown, which is a schematic diagram of the deformed state of the torsion beam 1-1, Figure 3 is a schematic diagram of the state of the torsion beam 1-1 after being corrected by embodiment 2 of the present application. Regarding the application scenarios of embodiment 1 and embodiment 2, as Figure 6 shown, the wheel inclination angle is observed from the perspective directly in front of the vehicle; when A>B, the scheme of embodiment 2 is used for adjustment; when A<B, the scheme of embodiment 1 is used for adjustment.

[0040] Based on the above technical solution, as Figure 5 shown, the first fixing frame 1 of the present application can be provided with a first main body frame 11, a first upper pressure plate 12, a first lower pressure plate 13 and a first locking assembly 14; during installation, the torsion beam 1-1 is placed between the first upper pressure plate 12 and the first lower pressure plate 13, and then the first upper pressure plate 12 and the first lower pressure plate 13 are connected by the first locking assembly 14, that is, the first upper pressure plate 12, the first lower pressure plate 13 and the first locking assembly 14 together enclose a space for clamping and fixing one end of the torsion beam 1-1.

[0041] Based on the above technical solution, as Figure 3As shown, the structure of the second fixing frame 2 can refer to that of the first fixing frame 1. The second fixing frame 2 of this application can be configured as a second main frame 21, a second upper pressure plate 22, a second lower pressure plate 23, and a second locking assembly 24. During installation, the torsion beam 1-1 is first placed between the second upper pressure plate 22 and the second lower pressure plate 23, and then the second upper pressure plate 22 and the second lower pressure plate 23 are connected by the second locking assembly 24. That is, the second upper pressure plate 22, the second lower pressure plate 23, and the second locking assembly 24 together form a space for clamping and fixing the other end of the torsion beam 1-1.

[0042] Based on the above technical solution, this application also provides a force transmission area 10 on the first fixed frame 1 for the piston end 312 to act and cooperate. The force transmission area 10 is used to receive and transmit the force applied by the piston end 312. That is, when the piston end 312 acts on the force transmission area 10 on the first fixed frame 1, it transmits the force to the first fixed frame 1, and then the first fixed frame 1 drives the torsion beam 1-1 to deform to achieve correction.

[0043] This invention uses a first fixing frame 1 and a second fixing frame 2 to fix the torsion beam 1-1 at both ends, and combines a transmission mechanism to apply a directional force, which can effectively correct the bending and twisting deformation of the torsion beam 1-1 and restore its geometric shape. Compared with traditional manual hammering or pry bar correction, this solution changes the relative position of the first fixing frame 1 and the second fixing frame 2 through the transmission mechanism, thereby realizing the correction of the torsion beam, reducing the skill requirements of the operator and reducing secondary damage caused by human error.

[0044] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
