Description

Installation structure for double-wishbone rear independent suspension of off-road vehicle

technical field

The utility model relates to automobiles, in particular to a double-wishbone rear independent suspension mounting structure for off-road vehicles.

Background technique

Double wishbone independent suspension has been widely used in the front wheel suspension of cars due to its good handling stability and comfort. However, due to its complex structure and taking up a large space, the scope of application of this type of suspension on the rear wheels of automobiles is limited. However, due to its advantages such as large lateral rigidity, excellent anti-roll performance, and good grip performance, it can meet the driving needs of vehicles in complex road conditions when used on off-road vehicles. As off-road SUVs begin to develop toward non-load-bearing trends, the double-wishbone rear independent suspension has begun to be reflected on load-bearing off-road vehicles. It is difficult to reconcile the space of the driving axle shaft, which affects the use of this type of suspension in the rear of off-road vehicles.

Contents of the invention

The purpose of this utility model is to solve the above-mentioned deficiencies in the background technology, to provide a double-wishbone rear independent suspension installation structure suitable for off-road vehicles, to realize the support and fixation of the suspension, and to reduce the installation height of the suspension. The height decreases accordingly, increasing the seating space.

The technical scheme of the utility model is: a double-wishbone rear independent suspension installation structure for an off-road vehicle, including a double-wishbone rear independent suspension and a rear longitudinal beam, which is characterized in that it also includes a mounting beam and a transition beam. The outer side of the double-wishbone rear independent suspension is connected to the hub motor in the rear wheel, and the upper connecting arm of the double-wishbone rear independent suspension is connected to the rear longitudinal beam;

The two ends of the installation beam are respectively connected to the lower connecting arms of the double-wishbone rear independent suspension on both sides, and the transition beam is a U-shaped structure correspondingly arranged above the installation beam. Side rear side member connection.

Preferably, the bottom of the U-shaped structure of the transition beam is integrally connected with the installation beam.

Further, the transition beam includes a horizontal beam and a vertical beam connected to both ends of the horizontal beam, the vertical beam is connected to the bottom surface of the rear longitudinal beam on the same side, and the horizontal beam is lower than the bottom surface of the rear longitudinal beam and is attached to the installation beam. combined connection.

Preferably, the double-wishbone rear independent suspension is provided with two lower connecting arms, and the installation crossbeam is provided with two, respectively connecting two pairs of lower connecting arms of the double-wishbone rear independent suspension on both sides. .

Further, there are two transition beams.

Preferably, it also includes a body floor, the shape of the body floor is a U-shaped structure corresponding to the shape of the transition beam, the two arms of the U-shaped structure of the body floor are connected to the inner side of the rear longitudinal beam, and the bottom of the U-shaped structure is connected to the transition beam.

The beneficial effects of the utility model are:

1. The car is driven by the wheel hub motor, eliminating the need for the traditional driving half shaft, so that the height of the suspension installation beam can be reduced as much as possible, and then the support rigidity is improved by directly installing the rear longitudinal beam at the inner end of the wheel cover on both sides of the body floor. Suspension support and fixation are achieved by adding simple fixed beams (installation beams, transition beams) at the lower end of the floor. The utility model has a simple and reliable structure, and because the height is lowered, the floor height of the vehicle body can also be lowered accordingly, which also improves the convenience of picking and unloading luggage at the rear end, increases the passenger space, and expands the double-wishbone independent suspension The scope of use of the rack.

2. Install the beam, transition beam, rear longitudinal beam and body floor to form a closed rectangular frame, which greatly increases the strength and rigidity of the vehicle system. The support force is transmitted to the body, and the rigidity of the suspension support is improved by using the closed frame formed by the body.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figure 1-2, the utility model includes a double-wishbone rear independent suspension 1, a rear longitudinal beam 2, a mounting beam 3, a transition beam 4 and a body floor 8. In this embodiment, the two sides are the lateral sides of the vehicle body. . The double-wishbone rear independent suspension 1 includes an upper connecting arm 6 and a lower connecting arm 7. There are two upper connecting arms 6 and lower connecting arms 7, which are A-shaped structures connected on the outside and separated on the inside. The upper connecting arm 6 and the The outer side of the lower connecting arm 7 is connected with the hub motor 5 in the rear wheel, and the end of the upper connecting arm 6 is connected with the rear longitudinal beam 2 on the same side.

The lower connecting arms 7 of the double-wishbone rear independent suspension 1 on both sides form two corresponding pairs in the transverse direction, and the installation beams 3 are two, respectively connecting the two pairs of lower connection arms corresponding to the transverse direction of the double-wishbone rear independent suspension 1 on both sides. The arm 7 is hinged to the end of the mounting beam 3 and the lower connecting arm 7 . The transition beam 4 is correspondingly arranged above the installation beam 3. The transition beam 4 and the installation beam 3 are two. The transition beam 4 includes a horizontal beam 4.1 and a vertical beam 4.2 connected to the two ends of the horizontal beam 4.1. The horizontal beam 4.1 and the vertical beam 4.2 Form a U-shaped structure, the vertical beam 4.2 (the two arms of the U-shaped structure of the transition beam) is connected to the bottom surface of the rear longitudinal beam 2 on the same side, and the horizontal beam 4.1 (the bottom of the 4 U-shaped structure of the transition beam) is lower than the bottom surface of the rear longitudinal beam 2 and It is fitted and connected with the installation beam 3 to form a whole.
