Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, unless otherwise specified, the use of directional words such as "upper, lower, left, and right" generally refers to upper, lower, left, and right in the drawings, "longitudinal" generally refers to the length direction of a vehicle, "transverse" generally refers to the width direction of a vehicle, and the terms "first" and "second" are used for descriptive purposes only and are not to be construed as limiting the relevant components.

Referring to fig. 1, an exemplary embodiment of a torsion beam according to the present disclosure is shown. As shown in fig. 1, the torsion beam includes a trailing arm 1 and a cross member 2, wherein the cross member 2 extends in the lateral direction, and the trailing arms 1 at both ends of the cross member 2 extend in the longitudinal direction. As described above, once the torsion beam is assembled, for example, the cross beam is welded and fixed to the trailing arm, the overall performance is substantially determined. Therefore, the crossbeam 2 and the trailing arm 1 are detachably connected, so that the assembly is convenient, the flexibility of the torsion beam in the aspect of adjusting performance is improved, and the development cost is saved.

The detachable connection can be achieved in various ways, for example, by connecting the transverse beam 2 to the trailing arm 1 directly by means of fasteners, etc. As shown in fig. 1, in the specific embodiment of the present disclosure, the cross beam 2 and the trailing arm 1 are mainly connected by the connecting clamp 3, wherein, in the transverse direction, both ends of the cross beam 2 are detachably connected with the trailing arm 1 by the connecting clamp 3, so as to facilitate the installation and the detachment of the cross beam 2 and the trailing arm 1.

The connecting clamp 3 can have a variety of configurations. Referring to fig. 2, in one embodiment, the connecting fixture 3 includes a fixture body having a longitudinal through hole 31 formed therein, so that the trailing arm 1 can be connected to the fixture body through the longitudinal through hole 31, and the cross beam 2 is detachably connected to the fixture body, so that the cross beam 2 can be detachably connected to the trailing arm 1, for example, the cross beam 2 is directly mounted to the fixture body through the first fastening member 4, so as to facilitate mounting and dismounting. Preferably, a transverse connecting shaft portion 35 extending transversely from the clamp body, the cross member 2 being detachably connected to the transverse connecting shaft portion 35, for example, by a bushing connection, by a first fastener 4, or the like. It can be seen that through setting up transverse connection axial region 35 for crossbeam 2 can be farther apart from trailing arm 1 in horizontal, avoids the appearance of the condition such as installation interference, makes crossbeam 2 be connected more firmly with the anchor clamps main part.

The transverse connecting shaft 35 is formed as a substantially hollow shaft section, and transverse connecting holes 36 are formed at the free end of the transverse connecting shaft 35 and distributed along the circumferential direction, i.e. the axes of the transverse connecting holes 36 are parallel to the axis of the cross beam 2.

Referring to fig. 3, which shows a structural schematic view of the cross member 2, it can be seen that the cross member 2 includes a beam main body 21 and a flange 22 radially extending from the beam main body 21 such that the flange 22 can be connected to the lateral connecting hole 36 by the first fastening member 4. The hollow design of the transverse connecting shaft portion 35 can provide space for the end of the beam body 21 to project into, in other words, provides installation space for the cross beam 2 to avoid interference. Further, as shown in fig. 3, the beam main body 21 is non-cylindrical, but is partially cylindrical as taken in the axial direction, that is, the cross section of the cross beam 2 is formed as an arc surface, and accordingly, the flange 22 is also formed as an arc surface. As shown in fig. 1 and 3, the cross member 2 is arranged in a form that the circular arc opening is directed downward, and since the cross member 2 is detachably mounted on the jig main body through the flange 22, the cross member 2 can be detached and mounted again after being rotated by a certain angle (for example, the circular arc opening is directed upward), so that the performance of the torsion beam can be adjusted, and specifically, the torsional rigidity of the torsion beam can be controlled. In addition, it can be understood that the cross beam 2 can be replaced according to the requirement of performance adjustment, for example, the cross beam 2 with smaller circular arc cross section area is replaced by the cross beam 2 with larger circular arc cross section area. Specifically, the diameter of the arc of the beam 2 can be kept constant, and the size of the cross-sectional area of the arc can be realized by changing the form of the arc length of the cross section. It can be understood that, by using the cross beams with different cross-sectional areas, the torsional rigidity of the torsion beam is correspondingly changed, so that the torsion beam is suitable for research and development of various vehicles, and development cost is saved. In the course of detailed research and development, whether the cross beam 2 is rotated or replaced, in order to ensure smoother reconnection with the jig main body, it is preferable to uniformly distribute the plurality of lateral connection holes 36 on the lateral connection shaft portion 35 of the jig main body in the circumferential direction, whereby the versatility of connection between the jig main body and the cross beam 2 can be improved. It should be noted that although fig. 3 shows a cross beam having a circular arc cross section, cross beams having other cross sectional shapes are also applicable to the present disclosure as long as the cross section of the lateral connecting shaft portion 35 is adaptively changed.

Further, the jig main body may be formed substantially as a block-shaped body having the longitudinal through hole 31, and specifically may include a first clamping portion 32, a second clamping portion 33, and a connecting portion 34. The connecting portion 34 connects a first end of the first clamping portion 32 and a first end of the second clamping portion 33, and a second end of the first clamping portion 32 and a second end of the second clamping portion 33 are respectively the other ends opposite to the first end of the first clamping portion 32 and the first end of the second clamping portion 33. Thereby, the first clamping portion 32, the second clamping portion 33 and the connecting portion 34 may enclose the aforementioned longitudinal through hole 31. Meanwhile, the second end of the first clamping portion 32 and the second end of the second clamping portion 33 are connected through the second fastening member 5 to achieve adjustment of the radial size of the longitudinal through hole 31, so that the trailing arm 1 is loosened or clamped, and the installation and the disassembly of the trailing arm 1 are facilitated.

In the structure in which the jig main body includes the first clamping portion 32, the second clamping portion 33, or the connecting portion 34, the lateral connecting shaft portion 35 for connecting the cross member 2 may be formed on the first clamping portion 32, the second clamping portion 33, or the connecting portion 34. As shown in fig. 2, a lateral connecting shaft portion 35 is formed on the connecting portion 34. It is to be understood that the clamp body of the attaching clamp 3 may be installed after being rotated by a certain angle about the longitudinal direction as an axis according to actual needs, and in this case, the lateral attaching shaft portion 35 may be formed on the first clamping portion 32 or the second clamping portion 33.

Based on the torsion beam described above, the present disclosure also relates to a vehicle employing the torsion beam. This openly passes through coupling fixture 3 detachably with trailing arm 1 and crossbeam 2 for crossbeam 2 can be fixed on coupling fixture 3 with the angle of difference, from this with the help of the change of crossbeam 2 circular arc opening direction, controls torsion rigidity of torsion beam, thereby controls the influence of torsion beam to the vehicle, and then practices thrift development cost.
