Description

Torsion beam type suspension and reinforcing member for torsion beam type suspension
Technical Field
The present invention relates to a torsion beam type suspension and a reinforcement member (reinforcement) for the torsion beam type suspension.
Background
Torsion beam type suspensions are mainly used for driving rear wheels of vehicles with front wheels. A long strip member, i.e., a torsion beam, is fixed between a pair of left and right trailing arms. Wheels are supported on the trailing arms. When the wheel is displaced due to irregularities of the road surface or the like, the torsion beam is twisted or flexed to be elastically deformed, thereby allowing the trailing arm to be displaced. When the road surface becomes flat, the torsion beam returns to the original shape, and the trailing arm and the wheel return to the original positions.
Patent document 1 discloses a torsion beam type suspension including a torsion beam having a low rigidity portion with a U-shaped cross section and a high elasticity portion with a cross section shaped as コ. A reinforcement is joined to the torsion beam so as to avoid the high rigidity portion.
Patent document 2 discloses a torsion beam type suspension in which the cross-sectional shape of the torsion beam near the center portion is U-shaped and the cross-sectional shape of the torsion beam on the end portion side is V-shaped. The case is described where the torsion beam is supported from the bottom surface side by two reinforcing members and the torsion beam is supported so as to be sandwiched from the front surface side by one reinforcing member.

Disclosure of Invention
Technical problem to be solved by the invention
In the torsion beam type suspension of patent document 1, the edges of the side plate (reference numeral 64) and the base plate (reference numeral 62) are welded, thereby joining the reinforcement to the torsion beam. The side plates and the base plate have difficulty in tracking the torsion or deflection of the torsion beam, so that the torsion beam and the reinforcement are easily separated at the welded portion when the torsion or deflection is generated at the torsion beam. In the torsion beam type suspension of patent document 2, if torsion or deflection occurs in the torsion beam, stress is concentrated on the front end of the reinforcing member, and there is a possibility that a crack occurs in the torsion beam.
The invention aims to provide a torsion beam type suspension and a reinforcing member, which can prevent stress from concentrating on the front end of the reinforcing member when torsion or deflection occurs on a torsion beam.
Solution for solving the above technical problem
The above technical problem is solved by a torsion beam type suspension comprising: a pair of left and right trailing arms; a torsion beam having one end side and the other end side fixed to the trailing arm; and a reinforcement member having a base end fixed to the trailing arm and a tip end fixed to the torsion beam, wherein the reinforcement member has a plate shape, and includes a tapered portion and a split portion on the tip end, the reinforcement member has a tip end shape in which a width of the tip end is gradually reduced with respect to a width of the base end by the tapered portion, the reinforcement member has a shape in which the tip end is split into a plurality of projections by the split portion, and the projections have inflections that change an angle so that an inclination angle of the projections is gradually reduced in the middle thereof.
The above-described problems are solved by a reinforcing member for a torsion beam type suspension, comprising: a base end portion for fixing to the trailing arm; and a tip end portion fixed to the torsion beam, wherein the tip end side of the reinforcing member has a shape in which a width of the tip end side is gradually reduced with respect to a width of the base end side by the tapered portion, the tip end portion is divided into a plurality of projections by the dividing portion, and the projections have inflections that change an angle by making an inclination angle of the projections gradually gentle midway therebetween.
The reinforcing member has a bent portion on the projection. Thus, when torsion or deflection occurs in the torsion beam, stress acting on a contact point between the front end side of the reinforcing member and the torsion beam can be dispersed, and damage such as cracking of the torsion beam can be prevented.
Preferably, the reinforcing member has a lightening hole at a root portion of the projection. By providing the lightening hole in the root portion of the tapered portion, it is possible to prevent stress from concentrating on the member near the root portion of the projection when torsion or flexure occurs at the torsion beam.
Preferably, the protrusion comprises: a tapered portion, a bent portion, and a tip portion inclined in a direction in which a width becomes narrower with respect to a width of the base end side of the reinforcing member. When torsion or deflection occurs at the torsion beam, stress acting on the front end portion can be dispersed and reduced by the inflection portion.
Preferably, the inflection portion is arranged such that L1/L2 is in the range of 1.4 or more when the length from the point of the distal end side of the protrusion, which is in surface contact with the torsion beam, to the distal end of the reinforcing member is L1 and the length from the point of surface contact to the inflection portion is L2. By setting this ratio to 1.4 or more, the stress acting on the tip of the reinforcing member can be further reduced.
Preferably, the torsion beam has a flat surface, and the front end side of the reinforcing member is fixed in contact with the flat surface. By surface-fixing the front end side of the reinforcing member to the torsion beam, it is possible to prevent the breakage from the fixing portion.
Preferably, the reinforcing member and the torsion beam are welded to each other at the distal end portion, the outer sides of the inflection portion and the tapered portion, and the base end side of the dividing portion. This can further reduce the stress acting on the tip of the reinforcing member.
Effects of the invention
A torsion beam type suspension and a reinforcement member are provided, which prevent stress from concentrating on the front end of the reinforcement member when torsion or deflection occurs at a torsion beam.

Detailed Description
The embodiments of the present invention will be described with reference to the accompanying drawings.
Fig. 1 to 7 show an example of a torsion beam type suspension. The torsion beam type suspension 1 includes a pair of left and right trailing arms 11, a torsion beam 12 having one end and the other end fixed to the trailing arms 11, a pair of reinforcing members 13 fixed to the trailing arms 11 and the torsion beam 12 on the bottom surface side, and a second reinforcing member 14 fixed to the trailing arms 11 and the torsion beam 12 on the front surface side (in plan view).
As shown in fig. 1 and 2, the trailing arm 11 includes: a bush 15 disposed outside the end portion on the vehicle front side; a wheel support portion 16 disposed outside an end portion on the vehicle rear side; and a bracket 17 for receiving the lower end of the suspension coil (not shown). The torsion beam type suspension 1 is attached to a member on the vehicle side so as to be swingable in the vertical direction via a bushing 15. In the present embodiment, the trailing arm 11 is formed into a curved shape with a depressed central portion in a plan view by joining 2 pieces of bent steel plates by welding. Therefore, the trailing arm 11 is a hollow member.
As shown in fig. 4 and 7, the torsion beam 12 has a substantially U-shaped cross section including the flat surface 18 and a pair of flanges 38 protruding downward from the flat surface 18, and the end portions of the flanges 38 are bent outward, and the cross section is continuous in the longitudinal direction. As shown in fig. 1, one end and the other end of the torsion beam 12 are fixed to the center portions of the right and left trailing arms 11, respectively, by welding.
The base end of the reinforcement member 13 is fixed to the bottom surface side of the trailing arm 11, and the tip end thereof is fixed to the bottom surface side of the torsion beam 12. As shown in fig. 5, the reinforcement member 13 is a plate-like member inclined from the base end side toward the tip end side, and the base end portion is fixed to the bottom surface side of the center portion of the trailing arm 11 by welding. The front end portion is fixed to the flat surface 18 on the bottom surface side of the torsion beam 12 by welding. As shown in fig. 2, at the tip end side of the reinforcing member 13, portions at the tip end side of a tip end portion 19, an inflection portion 20, and a tapered portion 22, which will be described later, are brought into surface contact with the bottom surface side of the flat surface 18 of the torsion beam 12. Further, as indicated by the X mark in fig. 2, the outer sides of the distal end portions of the distal end portion 19, the inflection portion 20, and the tapered portion 22 are welded. Since the distal end portions 19, the inflected section 20, and the tapered section 22 are not located at deep positions, the welding operation can be easily performed. In another embodiment, as shown in fig. 13, when the arc portion on the base end side of the divided portion 23 is fixed by welding in addition to the portions on the tip end side of the tip end portion 19, the inflected portion 20, and the tapered portion 22, the stress acting on the tip end of the reinforcing member can be further reduced.
The reinforcing member 13 includes a tapered portion 22 and a divided portion 23 on the distal end side. The tapered portion 22 has a shape in which the width of the distal end side is gradually reduced relative to the width of the proximal end side. The shape of the distal end side is a shape of 2 protrusions 24 divided into a pair by the dividing portion 23. In the present embodiment, the number of the projections 24 is 2, but for example, the number of the divided portions may be 2 and the number of the projections may be 4, that is, two pairs. The shape of the dividing portion 23 is a drop shape (tear-drop shape) in which the diameter is enlarged as approaching the proximal end side and the tip is rounded. Therefore, the width of the projection 24 is continuous with little change in the base end side and the tip end side of the projection in a plan view. Thereby, when the torsion beam 12 is twisted or deflected, the base end side and the tip end side of the projection 24 can be elastically deformed to follow the twist or deflection, thereby dispersing the stress acting on the torsion beam 12 and the reinforcement member 13.
The reinforcing member 13 is divided into 2 projections 24 by the dividing portion 23. Therefore, when the torsion beam 12 is twisted or deflected, each protrusion 24 is elastically deformed independently to track the twist or deflection of the torsion beam 12, thereby enabling the stress acting on the torsion beam 12 and the reinforcement member 13 to be dispersed.
The reinforcement member 13 has an inflection portion 20 on the projection that changes the angle so that the inclination angle of the projection 24 in the tapered portion 22 becomes gentle midway therein. In the present embodiment, the inflection portion 20 is located between the base end of the dividing portion 23 and the tip end of the projection 24. The projection 24 includes a tapered portion 22, an inflection portion 20, and a tip portion 19 in this order from the base end side of the projection. In the present embodiment, when a straight line parallel to the extending direction of the torsion beam 12 is defined as 0 °, the inclination angle of the tapered portion 22 is 20 °, -20 °, and the inclination angle becomes 0 ° in the inflection portion 20 and continues to the front end portion 19 parallel to the extending direction as it is. By providing the inflection portion 20, stress acting on the front end of the projection 24 can be dispersed to reduce the stress value when the torsion beam 12 is twisted or deflected. The inflected section preferably changes the angle between the tapered section and the tip end section by 5 to 70 degrees or-5 to-70 degrees, and more preferably by 10 to 40 degrees or-10 to-40 degrees, for example.
As shown in fig. 8 and 9, when the length from the point on the base end side where the front end side of the reinforcing member 13 is in surface contact with the torsion beam 12 to the front end of the reinforcing member 13 is made L1, and the length from the point in surface contact to the inflection portion 20 is made L2, the inflection portion 20 is preferably arranged so that L1/L2 is in the range of 1.4 or more. By setting this ratio to 1.4 or more, it is possible to disperse the stress acting on the tip of the projection 24 when the torsion beam 12 is twisted or deflected, thereby further reducing the stress value. If the ratio is too large, the length of the tip end portion 19 becomes too large, and welding becomes troublesome and complicated, so the upper limit is preferably 10, and more preferably 5. L2 is not particularly limited, but is preferably 20 to 100mm, for example.
As shown in fig. 6, the reinforcing member 13 includes a reinforcing bulging portion 25 on the base end side connected to the trailing arm, and the bulging portion 25 is formed by, for example, press working or bending working. The rigidity of the base end side of the reinforcing member 13 can be improved by the bulge portion 25. Similarly, the shape is processed by press working or bending so as to gradually decrease from the base end side toward the tip end side as shown in fig. 6. The rib 26 is provided on the distal end side of the reinforcing member 13 by press working or bending working, and the reinforcing member 13 exhibits appropriate rigidity on the distal end side. The rib 26 is disposed along the edge of the reinforcing member 13 from the start of the tapered portion 22 to the inflection portion 20.
The second reinforcing member 14 is fixed to the front side of the trailing arm 11 at its base end side by welding, and is fixed to the front side of the torsion beam 12 at its tip end side. The second reinforcing member 14 is shorter than the reinforcing member 13 with respect to the extending direction, and reinforces the joint portion of the trailing arm 11 and the torsion beam 12 from the front side.
The torsion beam type suspension 1 described above is but one example. For example, the embodiment shown in fig. 10 may be mentioned. Fig. 10 is an enlarged bottom view of the front end of the reinforcing member 27 and the bottom surface of the torsion beam 12 in the torsion beam type suspension. The reinforcing member 27 is different from the torsion beam type suspension 1 described above in that a lightening hole 29 is provided in a root portion of the projection 28. The root portion is located on the base end side of the area where the tapered portion 22 makes surface contact with the torsion beam, and does not make surface contact with the torsion beam 12. By providing the lightening hole 29, the root portion is easily deformed when the torsion beam 12 is twisted or flexed, so that the stress at the regions (a and d of fig. 10) where the tapered portion 22 is in surface contact with the torsion beam 12 can be reduced.
Examples
In the torsion beam type suspensions shown in fig. 8, 9, 10, 11, 12, and 13, the stress at each position of a, b, c, and d in each figure when the displacement is forcibly applied in the opposite phase is simulated. Hereinafter, the torsion beam type suspensions shown in fig. 8, 9, 10, 11, 12 and 13 are referred to as example 1, example 2, example 3, comparative example 1, comparative example 2 and example 4, respectively. In example 1, L1/L2 is 1.7, and in example 2, L1/L2 is 1.3. The reinforcing member 13 in fig. 8 has the same configuration as the reinforcing member 13 shown in fig. 1 and 2, and the same applies to the case where the portions marked with X in fig. 2 are welded. The reinforcing member 30 in fig. 9 is different from the reinforcing member 13 in fig. 8 in that a short-length protrusion 31 of L1 is provided, and the other points are the same as those of the reinforcing member 13 in fig. 8. The reinforcing member 32 in fig. 11 is different from the reinforcing member 13 in fig. 8 in that the projection 34 does not have a inflected portion, the tapered portion 33 continues up to the tip, and the projection 34 does not have a divided portion. The weld is along the taper outside the blackened area. The reinforcing member 35 of fig. 12 is different from the reinforcing member 13 of fig. 8 in that the tapered portion 37 continues to the tip end and the projection 36 does not have a inflected portion. The welding is the same as in the case of fig. 8. The reinforcing member 39 of fig. 13 is basically the same as the reinforcing member 13 of fig. 8 in configuration, but is different from the reinforcing member 13 of fig. 8 in that welding is also performed inside the arc portion on the base end side of the divided portion. Note that the configurations of the torsion beam, the trailing arm, the second reinforcing member, and the like, which are not illustrated in fig. 8 to 13, are the configurations of fig. 1 and 2, and are common to the respective embodiments and the comparative examples.
As a result of the simulation, in examples 1 and 3, the stress was reduced by about 12 to 16% in the b-position and the c-position as compared with comparative example 1. In the b-position and c-position of examples 1 and 3, the stress was reduced by about 18 to 22% as compared with the b-position and c-position of comparative example 2, as compared with comparative example 2. In example 2, the stress was reduced by about 10 to 11% at the b-position and the c-position as compared with comparative example 1. In the case of example 2, the stress was reduced by about 15 to 17% in the positions b and c as compared with those of comparative example 2, as compared with comparative example 2. In example 3, the stress was reduced by about 8 to 10% at the a-position and the d-position as compared with comparative example 1. In example 4, the stress was reduced by about 14 to 18% at the b-position and the c-position compared to comparative example 1. In the case of examples 1 and 3, the stress was reduced by about 20 to 24% in the b-position and c-position as compared with those of comparative example 2, as compared with comparative example 2.
A torsion beam type suspension having the configuration of example 1, comparative example 1, and comparative example 2 was fabricated, and actually a test was performed in which displacements were forcibly repeatedly applied in opposite phases. As a result of this, comparative example 1 generated cracks in the torsion beam a minimum number of times, and then generated cracks in the torsion beam of comparative example 2. In example 1, no crack was generated in the torsion beam at the number of trials in the test.
