Optionally, first reinforcing ribs are arranged on two sides of the weight reduction groove.
Optionally, a lightening hole is formed in the lower portion of the steering knuckle body.
Optionally, the ratio of the opening area of the lightening hole to the area of the steering knuckle body is in the range of 0.28-0.33.
Optionally, the knuckle body is provided with the second strengthening rib between lightening hole and ball seat.
Optionally, the longitudinal section of the lightening hole is approximately parallelogram.
Optionally, the knuckle body is an aluminum alloy casting.
Optionally, the weight-reducing hole is located below the weight-reducing groove.
Optionally, the cross section of the weight-reducing groove is C-shaped.
In summary, the utility model has the following beneficial technical effects:
1. the weight reducing groove is formed in the gooseneck area of the upper section of the knuckle body, so that the optimal force transmission path of the knuckle body is designed under the condition that the rigidity and strength performance of the knuckle body are ensured, the redundant structure is reduced, the unsprung mass of an automobile is effectively reduced, and the operability, comfort and acceleration performance of the automobile are effectively improved;
2. by digging the weight reduction groove and the weight reduction hole in the non-stressed area and arranging the first reinforcing rib and the second reinforcing rib in the local area, the optimal material utilization rate and the optimal force transmission path are achieved, and the rigidity, the strength and the fatigue performance of the steering knuckle body are improved while the weight and the cost are reduced.

Detailed Description
The utility model is described in further detail below with reference to fig. 1-3.
The embodiment of the utility model discloses a steering knuckle for a vehicle.
Referring to fig. 1, 2 and 3, a steering knuckle for a vehicle includes a knuckle body 1, and a weight reduction groove 2 is formed in an upper gooseneck area of the knuckle body 1. By arranging the weight reduction groove 2 in the upper gooseneck area of the knuckle body 1, the optimal force transmission path of the knuckle body 1 is designed under the condition that the rigidity and strength performance of the knuckle body 1 are ensured, the redundant structure is reduced, the unsprung mass of an automobile is effectively reduced, and the operability, comfort and acceleration performance of the automobile are effectively improved.
The knuckle body 1 adopts an aluminum alloy casting. The weight of the steering knuckle body 1 is greatly reduced by using an aluminum alloy material, and the operability, comfort and acceleration performance of the automobile are improved.
The cross section of the weight reducing groove 2 is C-shaped.
The ratio of the slotted area of the weight-reducing slot 2 to the area of the knuckle body 1 is in the range of 0.28-0.33. In the present embodiment, the ratio of the slotted area of the weight-reduction groove 2 to the area of the knuckle body 1 is approximately 30%.
The first reinforcing ribs 3 are arranged on two lateral sides of the weight-reducing groove 2. The first reinforcing bead 3 is provided on the knuckle body 1 along the lateral extension of the knuckle body 1.
The lower part of the knuckle body 1 is provided with a weight reducing hole 4, and the weight reducing hole 4 is positioned below the weight reducing groove 2. The ratio of the opening area of the lightening hole 4 to the area of the knuckle body 1 is in the range of 0.28-0.33. In the present embodiment, the opening area of the lightening hole 4 is approximately 30% to the area of the knuckle body 1.
The lower material redundancy of the knuckle body 1 is more, and the knuckle body is not an important stress area, and the redundant structure can be reduced by arranging the weight reducing holes 4 at the lower part of the knuckle body 1, so that the automobile is beneficial to reducing the weight of the whole automobile, reducing the cost and improving the whole performance.
The knuckle body 1 is provided with second strengthening rib 5 between lightening hole 4 and ball seat, and second strengthening rib 5 is along transverse distribution at knuckle body 1.
The longitudinal section of the lightening hole 4 is approximately parallelogram. In the present embodiment, the longitudinal section of the knuckle body 1 is nearly rectangular.
In this embodiment, the weight-reducing groove 2 and the weight-reducing hole 4 are both disposed in the non-stress area of the knuckle body 1, so that the strength of the knuckle body 1 is not affected.
Based on the structure of lightweight knuckle, through dig weight-reducing groove 2 and lightening hole 4 in the non-atress region, local region arranges first strengthening rib 3 and second strengthening rib 5, reaches optimal material utilization and best biography power route, has improved knuckle body 1 rigidity, intensity and fatigue property when reducing weight and reducing the cost.
According to the utility model, under the condition of ensuring the rigidity and strength performance of the steering knuckle body 1, the weight reducing holes 4 and the weight reducing grooves 2 are added on the steering knuckle body 1, the first reinforcing ribs 3 and the second reinforcing ribs 5 are added to weaken the non-stressed area of the steering knuckle body 1, the local rigidity is increased, the performance attenuation caused by the weight reducing holes 4 and the weight reducing grooves 2 is balanced and added, and the steering knuckle body 1 is prevented from being damaged and broken due to insufficient fatigue strength performance of the steering knuckle body 1, so that the safety of passengers is endangered.
