DETAILED DESCRIPTION
[0026] The following is a description of an elastic connection tool for a suspension and a vehicle body mounting structure for a suspension with reference to the drawings according to various embodiments of the present disclosure. However, in the following description, the following definitions will be used, and the same symbols / numbers will be used for substantially the same components.
[0027] The terms "upper", "lower", "front", "rear", "left", and "right" refer to the positions of an object when it is located on a vehicle. In this embodiment, the elastic connection tool for the suspension is used for the left front wheel of the front suspension. In other words, in this embodiment, the vehicle body mounting structure for the suspension is the structure adopted by the left front wheel of the front suspension. The initial state of the elastic connection tool for the suspension or the vehicle body mounting structure for the suspension should be the state when the vehicle is stopped.
[0028] Figure 1 Schematically shown is the initial state of the vehicle body mounting structure 1A for the suspension (hereinafter, simply referred to as "vehicle body mounting structure 1A") according to the first embodiment of the present disclosure, as seen from the front (front). According to the first embodiment of the present disclosure, the vehicle body mounting structure 1A includes an elastic connection tool 2A for the suspension (hereinafter, simply referred to as "elastic connection tool 2A"). The vehicle body mounting structure 1A uses the elastic connection tool 2A to connect the vehicle body side member 3 and the suspension side member 4. The symbol O1 is the central axis (extending axis) of the first mounting member 21, which will be described later.
[0029] Figure 2 The vehicle body mounting structure 1A is shown from above. Here, the vehicle body side member 3 is a member that constitutes all or part of the vehicle body. The suspension side member 4 is a member that constitutes all or part of the suspension arm. The suspension side member 4 can rotate in the circumferential direction about the rotation center line O2. In this embodiment, the rotation center line O2 is orthogonal to the central axis O1 of the first mounting member 21 (hereinafter, simply referred to as "central axis O1").
[0030] In Figure 3 it is shown in a cross-section along Figure 1 X1-X1 in
[0031] The elastic connection tool 2A is provided with a first mounting member 21. The first mounting member 21 is configured as follows.
[0032] The first mounting member 21 includes a first mounting portion 21a which can be attached to the vehicle body side member 3 or the suspension side member 4. In this embodiment, the first mounting portion 21a is attached to the suspension side member 4. In this embodiment, the first mounting portion 21a is integrally formed with the suspension side member 4. That is, in this embodiment, the suspension side member 4 extends along the central axis O1 together with the first mounting portion 21a. Further, in this embodiment, the suspension side member 4 constitutes all or part of the upper arm or the lower arm of the front suspension. However, the first mounting portion 21a can be separately formed from the suspension side member 4. Similarly, in this case, the suspension side member 4 can constitute all or part of the upper arm or the lower arm of the front suspension.
[0033] Further, the first mounting member 21 includes a rotation shaft 21b extending in a direction intersecting the first mounting portion 21a. In this embodiment, the rotation shaft 21b can rotate in the circumferential direction about the rotation center line O2. In this embodiment, the rotation shaft 21b is a cylindrical shaft having the rotation center line O2 as the central axis. The rotation shaft 21b is attached to the front end of the first mounting portion 21a. In this embodiment, the rotation shaft 21b is attached to the front end on the vehicle body side of the first mounting portion 21a. In this embodiment, the first mounting member 21 is constituted by the first mounting portion 21a and the rotation shaft 21b as a single unit.
[0034] Next, the elastic connection tool 2A includes a second mounting member 22. The second mounting member 22 is configured as follows.
[0035] The second mounting member 22 includes a second mounting portion 22a which can be attached to the other one of the vehicle body side member 3 and the suspension side member 4. In this embodiment, the second mounting portion 22a is attached to the vehicle body side member 3. In this embodiment, the vehicle body side member 3 constitutes all or part of the vehicle body. In this embodiment, the second mounting portion 22a has a mounting hole (not shown) penetrating the second mounting portion 22a. The second mounting portion 22a can be coupled to the vehicle body side member 3 by passing a fastening element 30 such as a screw, a bolt or a pin through the mounting hole. However, the second mounting member 22 can be attached to the vehicle body side member 3 by a method other than the mounting hole.
[0036] In addition, the second mounting member 22 includes a bracket 22b continuous with the second mounting portion 22a. In this embodiment, the bracket 22b is located between two second mounting portions 22a. In this embodiment, the two second mounting portions 22a are arranged in the front-rear direction of the bracket 22b. In this embodiment, the second mounting member 22 is composed of two second mounting portions 22a and the bracket 22b as a single unit. In this embodiment, the second mounting member 22 is formed of a plate-like member. The bracket 22b has a recess C2 for accommodating the rotation shaft 21b of the first mounting member 21. In addition, the bracket 22b includes an opening A2 that allows the first mounting portion 21a of the first mounting member 21 to pass through in a swingable manner. In this embodiment, the opening A2 is a slit hole extending in the circumferential direction around the rotation center line O2. This allows the first mounting member 21 to swing around the rotation center line O2 in the circumferential direction along the opening A2.
[0037] Next, the elastic connection tool 2A includes a first elastic member 23. The first elastic member 23 is configured as follows.
[0038] The first elastic member 23 connects the rotation shaft 21b of the first mounting member 21 and the bracket 22b of the second mounting member 22. In this embodiment, the first elastic member 23 is connected to the bracket 22b at the front and rear positions of the first mounting portion 21a of the first mounting member 21.
[0039] Figure 4 along Figure 2 The cross-section along X2-X2 in shows the vehicle body mounting structure 1A. The cross-section along X2-X2 is a plane including the central axis O1 and the vertical axis (a line perpendicular to the paper surface in Figure 2 when the vehicle body mounting structure 1A is in its initial state). In this embodiment, the first elastic member 23 is further connected to the bracket 22b in the vertical direction. In addition, the first mounting portion 21a of the first mounting member 21 includes a third elastic member 25 located near the rotation shaft 21b. The third elastic member 25 extends from the rotation shaft 21b through the opening A2 of the bracket 22b and extends across the opening A2, as shown in Figure 4 In addition, in the inner surface of the bracket 22b, the suspension side inner surface f22b is configured as a curved surface having a contour line that forms an arc with a radius of curvature R (the radius of curvature is greater than the radius r of the rotation shaft 21b) centered on the rotation center line O2 of the rotation shaft 21b, as shown in the vertical cross-sectional view (the front view in this embodiment) in Figure 4 .
[0040] In addition, the elastic connection tool 2A includes a second elastic member 24. The second elastic member 24 is configured as follows.
[0041] The second elastic member 24 covers the front end side portion of the rotary shaft 21b on the side opposite to the first mounting portion. In this embodiment, the second elastic member 24 covers the vehicle body side front end portion of the rotary shaft 21b. In this embodiment, the second elastic member 24 covers the entire surface of the vehicle body side front end face f21b of the rotary shaft 21b (in Figure 4 this case, at least the outer surface of the right half portion of the rotary shaft 21b). Further, in this embodiment, the second elastic member 24 is integrally formed with the first elastic member 23. In this case, the second elastic member 24 can be regarded as a single elastic member together with the first elastic member 23. However, the second elastic member 24 can also be separately formed from the first elastic member 23.
[0042] As Figure 4 shown, when the second mounting member 22 is mounted on the vehicle body side member 3, the second elastic member 24 is disposed in a compressed state between the vehicle body side member 3 and the rotary shaft 21b along the extending direction of the central axis O1 of the vehicle body side member 3. In other words, the first mounting member 21 (suspension side member 4) is initially pushed toward the suspension side (in this case, the left side) by the force (restoring force) of the second elastic member 24. Referring to Figure 3 in this embodiment, in the state before the elastic connecting tool 2A is attached to the vehicle body side member 3, the second elastic member 24 protrudes more outward (in this embodiment, toward the vehicle body side) than the vehicle body side mounting surface f22 of the second mounting member 22. As a result, when the elastic connecting tool 2A is attached to the vehicle body side member 3, the second elastic member 24 is disposed in a compressed state between the vehicle body side member 3 and the bracket 22b. In this embodiment, the vehicle body side front end face f24 of the second elastic member 24 is a flat surface, the same as the mounting surface f3 of the vehicle body side member 3. However, as will be described later, the vehicle body side front end face f24 of the second elastic member is not limited to a flat surface.
[0043] In the vehicle body mounting structure 1A, when the first mounting member 21 is pushed into the vehicle body side along the central axis O1, the rotary shaft 21b of the first mounting member 21 presses the mounting surface f3 of the vehicle body side member 3 via the second elastic member 24. In response to this, the rotary shaft 21b of the first mounting member 21 resists the pressing force acting on the rotary shaft 21b and receives the force (restoring force) of the second elastic member 24 from the mounting surface f3 of the vehicle body side member 3 via the second elastic member 24 in the direction opposite to the pressing force. This enables the vehicle body mounting structure 1A including the elastic connecting tool 2A to increase the spring stiffness (spring constant) in response to an input from the extending direction of the first mounting member 21 (the extending direction of the central axis O1).
[0044] Figure 5 Schematically shows the operating state of the vehicle body mounting structure 1A. As Figure 5As shown, in the vehicle body mounting structure 1A, when the wheel is lifted (when the vehicle body side sinks), the first mounting member 21 (suspension side member 4) swings upward (rotates) about the rotation center line O2. At this time, the first elastic member 23 and the second elastic member 24 twist about the rotation center line O2 between the rotation shaft 21b of the first mounting member 21 and the bracket 22b of the second mounting member 22 in a direction opposite to the swinging direction (rotation direction) of the first mounting member 21. In other words, when the first mounting member 21 swings upward (rotates), the first elastic member 23 and the second elastic member 24 undergo shear deformation between the rotation shaft 21b of the first mounting member 21 and the bracket 22b of the second mounting member 22. According to the vehicle body mounting structure 1A including the elastic connection tool 2A, when the first mounting member 21 swings upward in the circumferential direction about the rotation center line O2, the torsional stiffness of the rotation shaft 21b about the rotation center line O2 can be increased.
[0045] Conversely, in the vehicle body mounting structure 1A, when the wheel moves downward (when the vehicle body is lifted), the first mounting member 21 (suspension side member 4) swings downward (rotates) about the rotation center line O2. Even at this time, the first elastic member 23 and the second elastic member 24 twist about the rotation center line O2 between the rotation shaft 21b of the first mounting member 21 and the bracket 22b of the second mounting member 22 in a direction opposite to the swinging direction (rotation direction) of the first mounting member 21. In other words, when the first mounting member 21 swings downward (rotates), the first elastic member 23 and the second elastic member 24 also cause shear deformation between the rotation shaft 21b of the first mounting member 21 and the bracket 22b of the second mounting member 22. According to the vehicle body mounting structure 1A including the elastic connection tool 2A, when the first mounting member 21 swings downward in the circumferential direction about the rotation center line O2, the torsional stiffness of the rotation shaft 21b about the rotation center line O2 can also be increased.
[0046] That is to say, the vehicle body mounting structure 1A including the elastic connection tool 2A can exhibit the same function as a conventional vibration damping bushing (cylindrical bushing) without using a cylindrical bushing. According to the conventional vehicle body mounting structure using a cylindrical bushing, an additional mounting bracket or the like is required to attach the outer cylinder of the vibration damping bushing to the vehicle body side member 3. In contrast, according to the vehicle body mounting structure 1A including the elastic connection tool 2A, the bracket 22b of the second mounting member 22 includes a recess C2 having an open side on the mounting surface (in this embodiment, the mounting surface f3 of the vehicle body side member 3), and the bracket 22b of the second mounting member 22 can be attached to the mounting surface (in this embodiment, the mounting surface f3 of the vehicle body side member 3) such that the second elastic member 24 protrudes from the recess C2. Therefore, compared with the cylindrical bushing, the vehicle body mounting structure 1A including the elastic connection tool 2A can reduce the number of components and can also simplify the elastic connection tool, that is, the vehicle body mounting structure. Therefore, according to the vehicle body mounting structure 1A including the elastic connection tool 2A, the number of components can be reduced and the structure can be simplified. As a result, the vehicle body mounting structure 1A including the elastic connection tool 2A can reduce the weight and can also reduce the total cost.
[0047] Incidentally, in the vehicle body mounting structure including the elastic connection tool, the second elastic member 24 may be provided with a hole. Here, the term "hole" refers to a recess or a through hole formed in the vehicle body side front end surface f24 of the second elastic member 24. In this case, if the size, shape, etc. of the hole 27 are appropriately changed, the spring stiffness (spring constant) input from the extending direction of the first mounting portion 21a can be adjusted.
[0048] Figure 6 Equivalent to along Figure 1 A cross-sectional view corresponding to the cross-section of X1-X1 in is schematically shown to illustrate the initial state of the vehicle body mounting structure 1B (hereinafter, simply referred to as "vehicle body mounting structure 1B") for a suspension according to the second embodiment of the present disclosure. The vehicle body mounting structure 1B uses an elastic connection tool 2B (hereinafter, simply referred to as "elastic connection tool 2B") for a suspension according to the second embodiment of the present disclosure to connect the vehicle body side member 3 and the suspension side member 4.
[0049] As Figure 6 shown, the second elastic member 24 of the elastic connection tool 2B is provided with a hole 27. If the hole 27 is provided in the second elastic member 24, the spring stiffness (spring constant) input from the extending direction (the extending direction of the central axis O1) of the first mounting portion 21a of the first mounting member 21 can be kept low. Therefore, according to the vehicle body mounting structure 1B including the elastic connection tool 2B, by appropriately changing the size, shape, etc. of the hole 27, the spring stiffness (spring constant) input from the extending direction of the first mounting portion 21a can be adjusted.
[0050] Incidentally, the second elastic member 24 may have a curved surface extending in the circumferential direction around the rotation center line O2 of the rotation axis 21b; and the vehicle body side member 3 may be provided with a curved surface that matches the curved surface of the second elastic member 24. In this case, the spring stiffness (spring constant) against the input in the extending direction from the first mounting portion 21a and the torsional stiffness around the rotation center line O2 of the rotation axis 21b can be increased.
[0051] Figure 7 equivalent to Figure 2 A cross-sectional view corresponding to the cross-section along X2-X2 schematically shows a vehicle body mounting structure 1C for a suspension according to a third embodiment of the present disclosure (hereinafter simply referred to as "vehicle body mounting structure 1C"). The vehicle body mounting structure 1C connects the vehicle body side member 3 and the suspension side member 4 using an elastic connection tool 2C for a suspension according to a third embodiment of the present disclosure (hereinafter simply referred to as "elastic connection tool 2C").
[0052] In the elastic connection tool 2C, as Figure 7 shown, in the vertical cross-sectional view (front view), the vehicle body side front end face f21b of the rotation axis 21b is formed by a curved surface extending in the circumferential direction around the rotation center line O2 of the rotation axis 21b. The curved surface protrudes toward the vehicle body side, and the mounting surface f3 of the vehicle body side member 3 includes a curved surface f31, as Figure 7 shown, which matches the vehicle body side front end face f24 of the second elastic member 24 in the vertical cross-sectional view (front view). In this case, the spring stiffness (spring constant) against the input in the extending direction from the first mounting portion 21a and the torsional stiffness around the rotation center line O2 of the rotation axis 21b can be increased. In this embodiment, the curved surface f31 of the vehicle body side member 3 is a recess formed in the mounting surface f3 of the vehicle body side member 3. The second elastic member 24 is arranged in a compressed state between the vehicle body side front end face f21b of the rotation axis 21b and the curved surface f31 of the vehicle body side member 3 along the central axis Ol in the same manner as in other embodiments. In this case, compared with the vehicle body side front end face f21b of the rotation axis 21b or the curved surface f31 of the vehicle body side member 3 being composed of a flat surface, the second elastic member 24 is not easily worn or displaced along the mounting surface f3 of the vehicle body side member 3 because the second elastic member 24 is uniformly compressed in the radial direction of the rotation center line O2 around the rotation center line O2 of the rotation axis 21b. Therefore, according to the vehicle body mounting structure 1C including the elastic connection tool 2C, the durability can be improved and the sliding (in the vertical direction in this embodiment) relative to the mounting surface f3 of the vehicle body side member 3 can be prevented.
[0053] In addition, the elastic connection tool for a suspension according to the present disclosure may further be provided with a pressing member 28 that presses the second elastic member 24 against the rotary shaft 23b. In this case, the second mounting member 22 can be attached while the second elastic member 23 is compressed, regardless of the shape of the mounting surface to which the second mounting member 22 is attached.
[0054] Figure 8 corresponding to a cross-section along Figure 1 Fig. shows an initial state of a vehicle body mounting structure 1E for a suspension (hereinafter simply referred to as "vehicle body mounting structure 1E") according to a fourth embodiment of the present disclosure. The vehicle body mounting structure 1E connects a wheel side member 31 and a suspension side member 4 using an elastic connection tool 2E for a suspension (hereinafter simply referred to as "elastic connection tool 2E") according to the fourth embodiment of the present disclosure.
[0055] In Figure 8 , reference numeral 32 is the wheel side member. The wheel side member 32 is a member connected to the wheel, such as a knuckle. Referring to Figure 8 , in the elastic connection tool 2E, the pressing member 28 is disposed inside the bracket 22b. The second elastic member 24 is disposed in a compressed state between the rotary shaft 21b and the pressing member 28 along the central axis O1. In this embodiment, the pressing member 28 is provided with a mounting portion 28a that can be attached to the wheel side member 32. In this embodiment, the pressing member 28 includes two mounting portions 28a, and between these two mounting portions 28a is a pressing portion 28b that presses the second elastic member 24. The pressing member 28 and the bracket 22b are attached to the wheel side member 32 together by a fastening element 30. According to the vehicle body mounting structure 1E provided with the elastic connection tool 2E, this allows the second mounting member 22 to be attached while the second elastic member 23 is compressed, regardless of the shape of the mounting surface to which the second mounting member 22 is attached.
[0056] Only some embodiments of the elastic connection tool for a suspension and the vehicle body mounting structure for the suspension according to the present disclosure are disclosed above, and various modifications can be made according to the scope of the claims. The various configurations used in the above embodiments can be used in combination with each other.
