Description

Technical Field

[0001] The utility model relates to the technical field of torsion bars, in particular to a high-strength and lightweight anti-rolling device. Background Art

[0002] After searching, the Chinese patent publication number is CN206797400U, and the publication date is 2017-12-26. It discloses a new type of anti-roll torsion bar device for subway vehicles, including a torsion arm, one end of the torsion arm is provided with a metal bearing, the other end of the torsion arm is provided with a rocker arm, the torsion arm and the rocker arm are fixedly connected by a locking piece, one end surface of the locking piece is provided with a clamping hole, the surface of the clamping hole is provided with a bayonet, one end of the rocker arm is provided with a torsion bar shaft, and the surface of the torsion bar shaft is provided with a support seat. The anti-roll torsion bar device for subway vehicles uses a locking piece to fix the two components together. When the product is repaired and overhauled, during the maintenance process, the bayonet on one side of the locking piece can be pulled out to separate the torsion bar shaft and the torsion arm. When the two parts are inspected by a magnetic particle flaw detector, cracks and other defects can be found to the greatest extent, effectively avoiding the continued use of defective products after maintenance, and improving the reliability of the maintenance of the anti-roll torsion bar product. Parts that meet the requirements for continued use after non-destructive testing and size testing can be assembled with new products and assembled together again. However, when the device is in use, since the material of the torsion bar is special steel with high density and heavy weight, when the torsion bar is connected to the torsion arm by shrink fitting, an external supporting component is required to support the torsion bar, which is not convenient to use.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1-3 As shown, the utility model is a high-strength, lightweight anti-roll device, comprising a torsion arm 1, a tension and compression rod 2 and a bearing seat 3, wherein two of the torsion arms 1, the tension and compression rod 2 and the bearing seat 3 are provided, and a torsion bar 4 is provided between the two torsion arms 1, and the torsion arm 1 and the torsion bar 4 are bonded by special glue so that they will not loosen during long-term use, and a positioning mechanism 5 is provided on the torsion arm 1; the positioning mechanism 5 comprises an upper fixing frame 51 fixedly connected to the upper part of the torsion arm 1 and a lower fixing frame fixedly connected to the lower part of the torsion arm 1 52, a screw rod 53 is threadedly connected to the upper fixing frame 51, one end of the screw rod 53 is rotatably connected to a pressure plate 54, a support plate 55 is fixedly connected to the lower fixing frame 52, the torsion bar 4 is located between the pressure plate 54 and the support plate 55, and a limiting mechanism 56 is arranged between the pressure plate 54 and the support plate 55. By wrapping the torsion bar 4 with the pressure plate 54 and the support plate 55 when installing between the torsion bar 4 and the torsion arm 1, the torsion bar 4 can be supported, which facilitates the installation of the torsion bar 4 and the torsion arm 1.

[0023] The torsion bar 4 is made of carbon fiber material, and the center of the torsion bar 4 is hollow. The torsion bar device is made of special carbon fiber material, and its excellent material properties are used to provide sufficient anti-roll stiffness. The sufficient strength of carbon fiber allows the bar to have an extra-long service life, meeting the vehicle's 30-year service life requirement, thereby achieving a design goal of both weight reduction and durability.

[0024] The pressing plate 54 and the supporting plate 55 are both in a semicircular ring shape.

[0025] Embodiment 2

[0026] Based on Example 1, see Figure 2-4 shown.

[0027] The limiting mechanism 56 includes a bent plate 561 fixedly connected to the pressing plate 54 and a connecting plate 562 fixedly connected to the supporting plate 55 . A through slot 563 is formed through the top of the connecting plate 562 .

[0028] The through slot 563 is slidably connected to the bent plate 561 , and the pressing plate 54 and the supporting plate 55 are tightly fitted.

[0029] The connecting plate 562 is threadedly connected with a bolt 6, and the bolt 6 is threadedly connected to the bent plate 561. By using the limiting mechanism 56 and the bolt 6 in cooperation, when the pressing plate 54 and the supporting plate 55 are fitted together, the pressing plate 54 can be prevented from shaking and deviating, which would affect the installation of the torsion bar 4 and the torsion arm 1.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] The working principle of the utility model is as follows: when the torsion bar 4 and the torsion arm 1 are bonded together by using special glue, the torsion bar 4 is placed on the support plate 55, and then the screw 53 is rotated so that the pressure plate 54 is pressed on the torsion bar 4, and the pressure plate 54 and the support plate 55 are fitted with each other, and the bent plate 561 is stuck in the through groove 563, and then the bent plate 561 and the connecting plate 562 are fixed by bolts 6, so that the mutual cooperation between the pressure plate 54 and the support plate 55 can be used to achieve auxiliary support for the torsion bar 4, and then the special glue is applied to the contact surface of the torsion bar 4 and the torsion arm 1, and then the torsion bar 4 and the torsion arm 1 are bonded and fixed, so as to facilitate the installation of the torsion bar 4 and the torsion arm 1.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
