Definitions
- the present invention relates to a shock absorber, and particularly relates to a shock absorber having a suspension spring and constituting a suspension of a vehicle.
- a shock absorber constituting a suspension in a vehicle is provided in a tire house of the vehicle, and an upper end portion is connected to a vehicle body side portion and a lower end portion is connected to an axle side portion of the vehicle.
- the shock absorber When the shock absorber is provided in the tire house, for example, as disclosed in JP2010-247678A, the shock absorber interferes with the tire by positioning the shock absorber on the rear side of the tire house on the back side of the tire. Avoid that.
- the height position of the bonnet tends to be lowered from the viewpoint of collision safety in vehicles, and accordingly, the upper end position of the tire house is lowered. Therefore, the height position where the shock absorber is provided is lower than before, and as a result, the lower end portion of the suspension spring wound around the shock absorber tends to be positioned on the back side of the tire.
- An object of the present invention is to provide a shock absorber that can prevent the lower end portion of the broken suspension spring from interfering with the tire even if the lower end portion of the suspension spring is broken.
- a shock absorber having a suspension spring, a cylinder having a lower end connected to an axle side portion having a tire, and a lower part provided on an outer periphery of the cylinder and supporting the lower end of the suspension spring.
- a lower spring receiver, the lower spring receiver includes a receiving portion on which a lower end of the suspension spring is seated, and an abutting portion continuous with the receiving portion, and the abutting portion has an outer diameter larger than the outer diameter of the cylinder. Have a diameter.
- FIG. 1 is a partial side view of a shock absorber according to an embodiment of the present invention.
- FIG. 2 is a partially enlarged longitudinal sectional view of the lower spring support in FIG.
- FIG. 3 is a partial longitudinal sectional view showing a shock absorber according to another embodiment of the present invention.
- a shock absorber 100 according to an embodiment of the present invention will be described with reference to FIGS.
- the shock absorber 100 includes a cylinder 1 whose lower end is connected to an axle side portion having a tire T, a lower spring receiver 2 provided on the outer periphery of the cylinder 1, and a lower spring receiver 2.
- a suspension spring S whose lower end is supported.
- the shock absorber 100 is a double cylinder type in this embodiment.
- the cylinder 1 is an outer cylinder.
- a cylinder is provided inside the cylinder 1, and a piston rod 3 is slidably inserted into the cylinder.
- the upper end side of the piston rod 3 protrudes upward from the upper end portion of the cylinder 1.
- the cylinder 1 is configured as a lower end side member, and is connected to an axle side portion of the vehicle via, for example, a knuckle bracket (not shown).
- the piston rod 3 is configured as an upper end side member, and is connected to a vehicle body side portion of the vehicle via a mount (not shown), for example.
- a cap-shaped bump stopper 4 having a downward U-shaped cross section is provided at the upper end of the cylinder 1.
- the piston rod 3 is inserted through a hole formed in the axial center portion of the upper end portion of the bump stopper 4.
- a gap is formed between the hole formed in the shaft core portion of the bump stopper 4 and the piston rod 3. Dust collected at the upper end of the bump stopper 4 through this gap is discharged below the bump stopper 4.
- a rod guide and a seal member that is held by the rod guide are provided inside.
- the rod guide guides the relative movement of the piston rod 3 in the axial direction with respect to the cylinder 1.
- the seal member seals between the piston rod 3 and the cylinder 1.
- the cylinder of the shock absorber 100 is partitioned into two pressure chambers by a piston provided at the end of the piston rod 3.
- the piston is provided with a damping force generating element that imparts resistance to the working fluid that moves between the two pressure chambers as the piston rod 3 moves.
- the damping force generating element exhibits a damping action.
- the lower spring receiver 2 is fixed to the outer periphery of the cylinder 1 by welding.
- the suspension spring S whose lower end is supported by the lower spring receiver 2 is formed by a coil spring that is a compression spring.
- the coil spring is made of metal.
- suspension spring S The upper end of the suspension spring S is locked to an upper spring support provided below the mount and provided at the upper end portion of the piston rod 3. Therefore, the suspension spring S provided between the lower spring receiver 2 and the upper spring receiver elastically supports the vehicle body with an urging force to be extended.
- the lower end of the suspension spring S is not ground. This is because when the lower end of the suspension spring S is unground, the strength against bending at the lower end portion of the suspension spring S is greater than when the lower end of the suspension spring S is ground. However, this embodiment does not exclude the case where the lower end of the suspension spring S is ground.
- the lower spring receiver 2 connects the receiving portion 21 on which the lower end of the suspension spring S is seated, the base portion 22 connected to the outer periphery of the cylinder 1, and the base portion 22 and the receiving portion 21.

- the base 22 is formed in a cylindrical shape whose inner circumference matches the outer circumference of the cylinder 1.
- the connecting portion 23 is formed in an annular shape having an appropriate width in the radial direction.
- the base 22 is positioned on the back side of the receiving part 21 and the connecting part 23. Instead of this, as shown in FIG. 3, it may be positioned above the connecting portion 23. In this case, dust falling through between the upper bump stopper 4 and the upper end of the cylinder 1 travels down the base 22 and falls downward, so that the boundary between the base 22 and the connecting portion 23 is dropped. The problem of dust accumulation can be avoided.
- the connecting portion 23 of the lower spring receiver 2 includes an outer annular portion 23 a continuously provided from the receiving portion 21 and an inner annular portion 23 b continuously provided from the base portion 22.
- the outer annular portion 23 a is an annular member that protrudes radially inward from the inner peripheral side of the receiving portion 21.
- the inner annular portion 23 b is an annular member provided so as to protrude radially outward from the upper end side of the base portion 22.
- the outer end portion (not shown) of the inner annular portion 23b and the inner end portion (not shown) of the outer annular portion 23a are connected by a contact portion 24 having an appropriate height dimension.
- a conventional lower spring receiver is similarly formed with a receiving portion, a base portion, and a connecting portion.
- the connecting portion 23 of the lower spring receiver 2 in the present embodiment the outer annular portion 23a provided continuously from the receiving portion 21 and the inner annular portion 23b provided continuously from the base portion 22 are separated.
- the height position of the annular portion 23b is set higher than the height position of the outer annular portion 23a.
- the outer peripheral end portion of the inner annular portion 23b having a height difference and the inner peripheral end portion of the outer annular portion 23a are connected by a cylindrical contact portion 24.
- the height dimension of the contact part 24 larger than the wire diameter dimension of the suspension spring S, for example, the outer periphery of the contact part 24 can reliably contact the inner periphery of the suspension spring S.
- the lower spring receiver 2 provided in the cylinder 1 is different from the conventional spring receiver of this type, and the abutting portion having an enlarged diameter with respect to the cylinder 1 at the connecting portion 23. 24.
- the abutting portion 24 having an expanded diameter is broken for some reason and the shortened suspension spring S moves to the tire T side, as shown by a two-dot chain line diagram in FIG. It is possible to prevent the suspension spring S from moving further toward the tire T by contacting the lower end S1 of the broken suspension spring S.
- the connecting portion 23 of the lower spring receiver 2 includes the abutting portion 24 having an enlarged diameter, and the lower end portion S1 of the suspension spring S in which the abutting portion 24 is broken is prevented. Therefore, the lower end S2 (see FIG. 1) of the folded suspension spring S on the side facing the tire T is prevented from moving further toward the tire T. Therefore, it is possible to avoid the lower end S2 of the broken suspension spring S from interfering with the tire T.
- the shock absorber 100 As a result, if the lower end S2 of the folded suspension spring S on the side facing the tire T moves toward the tire T and interferes with the tire T, the tire T may be damaged. For this reason, in the shock absorber 100 according to the present embodiment, the lower end portion S1 of the folded suspension spring S is formed by the expanded contact portion 24 of the lower spring receiver 2 on the side opposite to the side facing the tire T. The movement to the tire T is prevented. Thereby, it is avoided that the lower end part S2 of the suspension spring S folded on the side facing the tire T interferes with the tire T.
- the contact portion 24 having an enlarged diameter in the lower spring receiver 2 is arbitrarily selected as long as it can prevent the lower end S1 of the suspension spring S from being moved toward the tire T. May be formed.
- the formation of the swelled contact portion 24 in the lower spring receiver 2 may be performed by a method of welding a rising portion that rises like a screen to the connecting portion of the conventional lower spring receiver.
- the rising portion is provided by welding or the like, since it takes time to manufacture the lower spring receiver 2, it is basically preferable not to select it.
- the contact portion 24 is formed integrally with the connecting portion 23. As described above, since a separate member is not used to form the contact portion 24 in the cylinder 1, the number of parts is not increased.
- the contact portion 24 is not formed by retrofitting another component, there is no possibility that the contact portion 24 falls off due to rusting or deterioration of the retrofit portion, and the contact portion 24. It is possible to permanently maintain the arrangement state.
- the contact portion 24 is formed on the connecting portion 23 by press working. However, from the viewpoint that it is sufficient if the contact portion 24 is formed, other measures may be used. Since there are various specific measures for forming the contact portion 24, the description thereof is omitted here.
- the shape of the outer peripheral surface of the contact portion 24 is formed on a circumferential surface that is concentric with the outer peripheral surface of the tube 1 in consideration of the case where this type of spring support is pressed.
- the outer circumferential surface of the cylinder 1 may not be a concentric circumferential surface.
- the outer peripheral surface of the contact portion 24 may be formed as a corrugated surface continuous in the circumferential direction or a polygonal surface continuous with a plurality of flat surfaces without being concentric with the outer peripheral surface of the cylinder 1. In this case, it is possible to give hobbies to the appearance of the contact portion 24, that is, the cylinder 1.
- the contact portion 24 is formed over the entire circumference of the lower spring receiver 2, but prevents the lower end portion S ⁇ b> 1 of the folded suspension spring S from moving to the tire T side. From this point of view, the contact portion 24 may be formed only on the outer peripheral portion opposite to the outer periphery facing the tire T. In this case, the contact portion 24 gives the lower spring receiver 2 directionality.
- the outer annular portion 23a and the inner annular portion 23b in the connecting portion 23 are formed in a substantially flat annular shape.
- the outer annular portion 23a and the inner annular portion 23b function as the connecting portion 23, they may be formed in any shape other than the above.
- a lower end side portion (not shown) of the dust cover 5 is positioned as shown by a two-dot chain line diagram in FIG. Taking this into consideration, the contact portion 24 functions to close the opening between the cylinder 1 and the dust cover 5. Therefore, by providing the contact portion 24, it is possible to suppress the entry of dust from the outside into the dust cover 5.
- the suspension spring S is wound in a posture that does not tilt with respect to the shock absorber 100.
- the suspension spring S may be wound in a posture inclined with respect to the shock absorber 100. Even in this case, the contact portion 24 can prevent the lower end portion S1 of the broken suspension spring S from moving toward the tire T side.
- the lower end of the suspension spring S is in direct contact with the lower spring receiver 2.
- a rubber sheet may be provided between the lower end of the suspension spring S and the lower spring receiver 2. In this case, it becomes possible to suppress the occurrence of rust at the lower end of the suspension spring S, which may be caused by direct contact between the lower end of the suspension spring S and the lower spring receiver 2, and between them. Since shock absorption is possible, the generation of impact sound can be reduced.
- the lower spring receiver 2 is formed by press working, and the contact portion 24 is integrally formed.
- the contact portion 24 is made using another member. 24 may be provided.
