Detailed Description

Fig. 1 is a schematic perspective view of a steering system according to an embodiment of the present invention; fig. 2 is a schematic side view of a knuckle of the steering system shown in fig. 1. Referring to fig. 1 and 2, an embodiment of the present invention provides a knuckle, including: the steering knuckle comprises a steering knuckle body 1 and a steering knuckle arm 2 arranged on the outer side of the steering knuckle body 1, wherein the steering knuckle arm 2 is connected with a steering machine 4 providing steering power through a steering tie rod 3, and the steering function of a vehicle is achieved. The front and back of the knuckle arm 2 are provided with a pit 5, respectively.

The utility model discloses a steering knuckle, because the corresponding position on 2 two sides of steering knuckle arm all increases pit 5 structure, the thickness of the steering knuckle arm 2 at pit 5 place is thinner, consequently when taking place positive high-speed collision, 2 positions of the steering knuckle arm at pit 5 place can break earlier, the energy that very big part collision produced can be absorbed in the fracture of steering knuckle arm 2, can make the impact energy who transmits in the driver's cabin as few as possible, driver's foot places the deformation in having reduced vehicle A post lower part and the driver's cabin, so can protect driver's foot and shank, can reduce the injury that the collision led to the fact for the driver.

Fig. 3 is a schematic side view of a steering knuckle according to another embodiment of the present invention. Referring to fig. 3, the width dimension f of the end of the knuckle arm 2 close to the knuckle body 1 is larger than the width dimension e of the end of the knuckle arm 2 remote from the knuckle body 1, i.e., f > e. This ensures that the dimples 5 break off first upon impact.

Specifically, the concave pit 5 is provided at an end of the knuckle arm away from the knuckle body 1.

Wherein, two pit 5 direct casting shaping need not the processing, save the processing cost.

Fig. 4 is a partially enlarged schematic view of a portion I in fig. 3. Fig. 5 is a schematic cross-sectional view taken along a sectional line a-a in fig. 4. Referring to fig. 4 and 5, the edges 51 of two pits 5 are rounded. The bottoms 52 of the two dimples 5 are hemispherical and have a radius of at least 5 mm.

Thus, the steering knuckle is easier to demould during casting, and the phenomenon of stress concentration can be reduced.

Referring to fig. 5, the distance b between the bottom walls of two pockets 5 is at least 8 mm. Otherwise, the steering knuckle is not easy to cast or has defects after casting.

Referring to fig. 1, the knuckle further includes an upper knuckle arm 6 and a lower knuckle arm 7 disposed outside the knuckle body 1, the upper knuckle arm 6 being connected to a shock absorber 8, and the lower knuckle arm 7 being connected to a lower swing arm ball pin 9.

The knuckle upper arm 6 is connected with a shock absorber 8 for supporting the weight of the vehicle body and reducing the impact of the wheels on the vehicle body.

In fig. 1, the knuckle further includes two caliper mounting arms 10 for mounting a caliper, so that the braking performance of the entire vehicle can be achieved.

It should be noted that under the technical scheme of the utility model, each item test analysis index such as the intensity hardness of knuckle all satisfies technical requirement.

And the pit 5 structure also reduces the weight of the whole steering knuckle and improves the fuel economy of the whole vehicle.

Fig. 6 is a schematic diagram of the force transmission path of the knuckle of fig. 2 in a frontal high speed collision. Adopt the vehicle of the utility model discloses a knuckle, when the vehicle takes place high-speed head-on collision, the route of power transmission refers to figure 6, and the arrow in figure 6 represents the route of power transmission. The front part of the vehicle is crushed instantly, impact force acts on wheels and a steering knuckle, the steering knuckle moves backwards rapidly, a steering knuckle arm 2 is placed with the lower part of a column A of the vehicle and the feet of a driver in a cab to collide, in the collision process, the steering knuckle arm 2 is broken to absorb energy generated by a large part of collision, the impact capacity transmitted into the cab is reduced as much as possible, the placing deformation of the lower part of the column A of the vehicle and the feet of the driver in the cab is reduced, the steering knuckle arm 2 plays a role in buffering and energy absorption, the feet and the legs of the driver can be protected, and the injury to the driver caused by collision can be reduced.

Another embodiment of the present invention provides a vehicle having a knuckle as shown in fig. 2, so the specific structure of the knuckle is not repeated herein.

The utility model discloses a vehicle, when taking place high-speed head-on collision, because knuckle arm 2 can be in time cracked, absorb the energy that a very big collision produced, can make and transmit the interior impact capacity of driver's cabin as few as possible, reduce driver's foot in vehicle A post lower part and the driver's cabin and place the deformation, knuckle arm 2 plays the effect of buffering energy-absorbing, so can protect driver's foot and shank, can reduce the injury that the collision led to the fact for the driver.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
