Rear axle for a motor vehicle
View Patent ↗A rear axle is provided for a motor vehicle, in particular a passenger car, with two independent wheel suspensions, each of which include, but is not limited to a wheel carrier and a three-link arrangement connected therewith in an articulated manner with a longitudinal link and two transverse links. The two transverse links are each arranged in vehicle longitudinal direction next to each other, and with a transverse leaf spring arrangement, which is connected to the two independent wheel suspensions.
1. A rear axle for a motor vehicle comprising,
a first wheel suspension; and
a second wheel suspension that is independent of the first wheel suspension,
wherein the first wheel suspension and the second wheel suspension each comprise a wheel carrier, and
a three-link arrangement connected in an articulated manner to the wheel carrier with a longitudinal link and two transverse links, wherein the two transverse links are each arranged in a vehicle transverse direction next to one another;
a transverse leaf spring arrangement that is connected to the first wheel suspension and the second wheel suspension independently of the transverse links; and
a swing support connecting the transverse leaf spring arrangement to a shock absorber strut in an articulated manner.
2. The rear axle according to claim 1 , wherein the two transverse links are arranged on both sides of the transverse leaf spring arrangement.
3. The rear axle according to claim 1 , further comprising joints connecting the wheel carrier to the two transverse links, wherein the joints are arranged in a vehicle vertical direction at least substantially at the same height.
4. The rear axle according to claim 1 , wherein the transverse leaf spring arrangement comprises a connected transverse leaf spring of metal.
5. The rear axle according to claim 1 , wherein the transverse leaf spring arrangement comprises a progressive characteristic.
6. The rear axle according to claim 1 , further comprising a driveshaft arrangement connected to the wheel carrier for driving rear wheels connected to the wheel carrier.
7. The rear axle according to claim 1 , wherein the motor vehicle is a passenger vehicle.
8. The rear axle according to claim 1 , wherein the swing support is connected with an elastomer bushing to the shock absorber strut.
9. The rear axle according to claim 1 , wherein the transverse leaf spring arrangement comprises steel.
10. The rear axle according to claim 1 , wherein the transverse leaf spring arrangement comprises a fiber-reinforced plastic.
11. A motor vehicle, comprising:
a first wheel suspension; and
a second wheel suspension that is independent of the first wheel suspension,
wherein the first wheel suspension and the second wheel suspension each comprise:
a wheel carrier;
a three-link arrangement connected in an articulated manner to the wheel carrier, the three-link arrangement comprising:
a longitudinal link; and
two transverse links arranged in a vehicle transverse direction next to one another;
a transverse leaf spring arrangement that is connected to the first wheel suspension and the second wheel suspension independently from the transverse links; and
a swing support connecting the transverse leaf spring arrangement to a shock absorber strut in an articulated manner.
12. The motor vehicle, according to claim 11 , wherein the transverse leaf spring arrangement is connected to a structure of the motor vehicle in such a manner to provide a progressive characteristic.
13. The motor vehicle according to claim 12 , wherein the structure of the motor vehicle comprises two surfaces that are convex with respect to each other, between which is arranged the transverse leaf spring arrangement.
