The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0022] In order to describe the present invention in detail, first, the conversion bracket for two-wheel drive rear suspension and the vehicle of the present invention are specifically described below.

[0023] like Figure 1 As shown, the present application provides a conversion bracket for a two-wheel drive rear suspension, including a main body 1 and a connecting frame 2 connected to the main body 1. The main body 1 and the connecting frame 2 in this embodiment are integrally formed, and both are made of die-cast aluminum material for high-pressure pressing of blanks, which can not only improve the strength of the conversion bracket, but also reduce the connection time between the connecting frame 2 and the main body 1, thereby improving production efficiency. If the connecting frame 2 and the main body 1 are not integrally formed, they need to be connected by welding, which will increase production time.

[0024] The body 1 is connected to the transmission assembly. The body 1 is provided with a mounting hole 11 and a positioning structure. The positioning structure includes at least one positioning hole 12 and a positioning surface 13. The side of the body 1 away from the connecting frame 2 is the positioning surface 13.

[0025] The positioning surface 13 of the body 1 contacts the end face of the transmission. Designing the positioning surface 13 to match the end face of the transmission can improve the installation accuracy. When the positioning hole 12 of the conversion bracket is inserted into the positioning pin of the transmission, the first positioning is performed; the positioning surface 13 positions the conversion bracket along the axial direction of the transmission so that the conversion bracket will not tilt. When the subsequent mounting hole 11 connects the conversion bracket to the end face of the transmission, it can determine whether the bolts are tightened and perform secondary positioning. The positioning hole 12 and the positioning surface 13 are used to achieve three-dimensional positioning, so that the progress of the conversion bracket is better.

[0026] In order to achieve better accuracy, two positioning holes 12 are provided on the positioning surface 13 in this embodiment, and the two positioning holes 12 are not provided on the same side. Positioning holes 12 and mounting holes 11 are provided on both the upper and lower sides of the body 1, one positioning hole 12 is provided on the upper side, and one positioning hole 12 is provided on the lower side, that is, one positioning hole 12 and one mounting hole 11 are provided on the upper side, and two mounting holes 11 and one positioning hole 12 are provided on the lower side.

[0027] In some embodiments, the upper positioning hole 12 and the lower positioning hole 12 are staggered, and a support ear is provided on the upper side of the main body 1, and the upper positioning hole 12 is provided on the support ear. The positioning hole 12 is not subjected to force, so a gap can be provided between the upper support ear and the corresponding mounting hole 11 on the lower side. In this way, the main body 1 does not need to be provided so long, thereby saving materials and making the entire conversion bracket lightweight.

[0028] The positioning hole 12 on the lower side is arranged in the middle, which is equivalent to that the three mounting holes 11 form a triangle, so that the connection of the main body 1 is more stable.

[0029] Among them, the three mounting holes 11 are preferably formed into an acute triangle, so that the strength of the connection between the main body 1 and the end of the transmission is better. Because if it is an acute triangle, when the mounting hole 11 on the upper side is subjected to force, the force can be transmitted vertically to the other two mounting points on the lower side more evenly. If an obtuse triangle or a right triangle is used, the force of the mounting point on the upper side, the force transmitted to the mounting point at the obtuse angle point is greater than that of the other point, which may affect the life of the conversion bracket.

[0030] The upper side of the body 1 and the connecting frame 2 are both in the shape of an arc, and the connecting frame 2 is also in the shape of an arc, so that the conversion bracket is the same shape as the four-wheel drive connection shell after installation, which is convenient for subsequent installation. The outside of the connecting frame 2 away from the connection shell is the outer wall, and the inside of the connecting frame 2 in contact with the connection shell is the inner wall, which fits the outer wall of the connection shell. The connecting frame 2 is provided with two bosses 21 at both ends along the arc length direction, and each boss 21 is provided with at least two connection holes 22 for connecting the rear suspension to the conversion bracket. In this embodiment, two connection holes 22 are provided on each boss 21, and the two connection holes 22 are provided along the axis direction of the connecting frame 2.

[0031] In order to achieve lightweight of the whole vehicle, the weight of the conversion bracket should be reduced as much as possible without reducing the strength of the conversion bracket. In this embodiment, a plurality of first weight-reducing grooves 14 are provided on the body 1. The first weight-reducing grooves 14 are located on the side of the body 1 away from the connecting frame 2, and the first weight-reducing grooves 14 are recessed toward the side of the connecting frame 2. The first weight-reducing grooves 14 are arranged at intervals, so that the first weight-reducing grooves 14 not only reduce the weight of the body 1, but also are equivalent to providing a plurality of reinforcing ribs on the body 1.

[0032] The first weight-reducing groove 14 is arranged along the height direction of the body 1, that is, along the upper and lower sides of the body 1, rather than along the arc length direction of the connecting frame 2. The first weight-reducing groove 14 arranged up and down has better strength than that arranged along the arc length direction of the connecting frame 2.

[0033] The connecting frame 2 is generally arranged in the middle of the main body 1, rather than being arranged on the upper side or the lower side of the main body 1, so that the overall force of the main body 1 is more uniform.

[0034] In order to increase the strength of the connecting frame 2, a first reinforcing rib 24 is provided between the connecting frame 2 and the body 1. The first reinforcing rib 24 is located on the outer wall of the connecting frame 2, which is equivalent to providing a supporting force for the connecting frame 2. The connection between the connecting frame 2 and the body 1 is not only subjected to force in the vertical direction, but also in the lateral direction.

[0035] In some embodiments, the first reinforcing rib 24 is triangular, and the width of the first reinforcing rib 24 at the body 1 and the connecting frame 2 is greater than the width at the side away from the body 1. In this embodiment, a total of three first reinforcing ribs 24 are provided, of which the two outermost first reinforcing ribs 24 are both located at the position where the boss 21 is provided on the connecting frame 2, so that the connection of the rear suspension can be strengthened more directly. The positioning hole 12 on the lower side of the body 1 is correspondingly provided at the position of the middle first reinforcing rib 24, because the positioning hole 12 on the lower side does not need to be provided as a through hole, as long as the positioning pin can enter.

[0036] In detail, the outer wall of the connecting frame 2 is provided with a second reinforcing rib 25 along the arc length direction of the connecting frame 2. The second reinforcing rib 25 is divided into multiple sections by the first reinforcing rib 24. In order to make it better, two second reinforcing ribs 25 are provided on the outer wall of the connecting frame 2, and the two sides of another second reinforcing rib 25 are connected to the two bosses 21.

[0037] On the other hand, the present application also provides a vehicle, including a transmission assembly and the above-mentioned conversion bracket for two-wheel drive rear suspension, wherein the conversion bracket is mounted on the transmission assembly.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
