The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A toe-angle adjusting apparatus and a vehicle according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1 to 6, according to some embodiments of the present invention, the toe-angle adjusting device includes a hub bracket 12 connected to the hub, and an adjusting mechanism 13, the adjusting mechanism 13 is connected to one of the hub bracket 12 and the external torsion beam, and in a state of adjusting the toe-angle, the adjusting mechanism acts between the hub bracket 12 and the torsion beam to rotate the first end of the hub bracket (12) in a direction away from or close to the torsion beam to achieve the adjustment of the toe-angle.

It can be understood that the hub bracket 12 is connected with the wheel through the hub 2, and the adjusting mechanism 13 is connected to the hub bracket 12 or the external torsion beam, and when toe-in is adjusted, the adjusting mechanism 12 can act between the hub bracket 12 and the torsion beam, so that the first end of the hub bracket 12 rotates towards the direction far away from or close to the torsion beam to adjust the toe-in angle, and therefore the toe-in angle of the wheel can be conveniently adjusted while the occupied space is small.

It will be appreciated that the adjustment mechanism 13 may be provided on either the hub carrier or the outer torsion beam.

Preferably, the toe-in angle adjusting device 1 further includes a torsion beam bracket 11 fixed on the torsion beam, the second end of the hub bracket 12 is fixedly connected to the torsion beam bracket 11, and a gap is provided between the hub bracket 12 and the torsion beam bracket 11, so that under the action of the screw 131, the first end of the hub bracket 12 can move away from or close to the torsion beam bracket 11 by using the connection between the hub bracket 12 and the torsion beam bracket 11 as a rotation center, and the gap between the hub bracket 12 and the torsion beam bracket 11 can leave a sufficient space to move the first end of the hub bracket 12, thereby preventing interference between the hub bracket 12 and the torsion beam 11.

Preferably, the torsion beam bracket 11 is provided with a screw hole 111 at a position corresponding to the first end of the hub bracket 12, and the screw 131 passes through the screw hole 111 and is connected to the hub bracket 12, so that the acting point of the screw 131 is closer to the first end of the hub bracket 12, thereby moving the second end of the hub bracket 12 more conveniently and laborsavingly.

According to some embodiments of the present invention, the adjusting mechanism 13 further includes a threaded sleeve 132, the threaded sleeve 132 is disposed on the hub bracket 12, and the threaded rod 131 is threaded through the threaded sleeve 132, such that when the threaded rod 131 is rotated, the threaded sleeve 132 moves along an axial direction of the threaded rod 131 to drive the first end of the hub bracket 12 to rotate away from or close to the torsion beam bracket 11.

Specifically, the threaded sleeve 132 is disposed on the hub bracket 12 and can be fixedly connected to the hub bracket 12, and the threaded rod 131 is connected to the threaded sleeve 132, when the threaded rod 131 rotates, since the threaded sleeve 132 cannot rotate relative to the hub bracket 12, the threaded sleeve 132 moves along the axial direction of the threaded rod 131 along with the rotation of the threaded rod 131, so as to drive the first end of the hub bracket 12 to move away from or close to the torsion beam bracket 11, thereby adjusting the toe angle of the vehicle, it can be understood that, in this process, the threaded rod 131 is fixed and cannot move in the axial direction, so that the threaded sleeve 132 can move in the axial direction of the threaded rod 131.

According to some embodiments of the present invention, the hub bracket 12 is provided with a threaded sleeve hole 121, and the threaded sleeve 132 is fixedly disposed in the threaded sleeve hole 121; the threaded sleeve 132 includes an elastic portion and a rigid portion, the rigid portion is connected with the screw 131 so that the threaded sleeve 132 is forced to move when the screw 131 rotates, and the elastic portion is deformed when the rigid portion drives the hub bracket 12 to move so as to prevent the screw 131 from interfering with the rigid portion.

Specifically, the hub bracket 12 is provided with a threaded sleeve hole 121, and the threaded sleeve 132 is fixedly disposed in the threaded sleeve hole 121, that is, the threaded sleeve 132 cannot move relative to the hub bracket 12, so that the hub bracket 12 can be driven to move when the threaded sleeve 132 moves.

According to an embodiment of the present invention, the threaded sleeve 132 includes an elastic portion and a rigid portion, the rigid portion is connected to the threaded rod 131, so that the rotation of the threaded rod 131 can be converted into the axial movement of the threaded sleeve 132, because when the threaded sleeve 132 moves axially, the first end of the hub bracket 12 rotates around the connection point of the hub bracket 12 and the torsion beam bracket 11, and therefore, during the deflection movement of the first end of the hub bracket 12, the axis of the threaded sleeve 132 gradually changes from being coincident with the axis of the threaded rod 131 to intersecting, which causes interference between the threaded rod 131 and the threaded sleeve 132, and therefore, the threaded sleeve 132 is further provided with an elastic portion, and during the deflection movement of the first end of the hub bracket 12, the axis of the threaded sleeve 132 gradually intersects the axis of the threaded rod 131, and at this time, the elastic portion deforms, so that during the movement of the first end of the hub bracket 132, the axis of the threaded sleeve 132 and the axis of the threaded rod 131 always coincide, thus, interference between the threaded sleeve 132 and the screw 131 is prevented, and smooth relative movement is ensured.

It is understood that the threaded sleeve 132 may also be provided with a rigid tube around the periphery of the elastic portion and fixedly connected to the hub bracket through a rigid channel.

Preferably, the second through hole 123 is opened near the second end of the hub bracket 12, and in order to make the connection of the second through hole 123 more firm, two second through holes 123 are provided in the vertical direction perpendicular to the moving direction of the first end of the hub bracket 12, that is, the hub bracket 12 and the torsion beam bracket 11 are fixedly connected together by two bolts 137, and the two second through holes 123 provided in the vertical direction can make the deflection center of the first end of the hub bracket 12 be an axial direction perpendicular to the deflection direction, so that the deflection movement of the first end is stable, thereby better adjusting the toe-in-front angle and improving the adjustment precision.

According to some embodiments of the present invention, adjustment mechanism 13 further includes a first washer 139, wherein first washer 139 is disposed between first upright plate 112 and second upright plate 122 to space first upright plate 112 and second upright plate 122; the bolt 137 is coupled to the nut 138 through the first through hole 113, the first washer 139, and the second through hole 123.

Preferably, in order to keep the torsion beam bracket 11 and the hub bracket 12 spaced apart, a first washer 139 is disposed between the first upright plate 112 and the second upright plate 122 to form a gap between the first upright plate 112 and the second upright plate 122, so that the first end of the hub bracket 12 can move not only in a direction away from the first upright plate 112, but also in a direction close to the first upright plate 112, and thus interference is avoided during movement; the bolt 137 may sequentially pass through the first through hole 113, the first washer 139 and the second through hole 123 to be connected with the nut 138, at this time, the nut 138 is disposed on the side of the second vertical plate 122 away from the first vertical plate 112, and the nut may be fixedly connected with the second vertical plate 122, or certainly may not be connected with the second vertical plate 122; bolt 137 may also pass through second through hole 123, first washer 139, and first through hole 113 in sequence to be connected with nut 138, at this time, nut 138 is disposed on the side of first vertical plate 112 far from second vertical plate 122, and the nut may be connected with first vertical plate 112, or may not be connected.
