In view of the above, in the knuckle of the vehicle of the present utility model, the second arm portion located on the rear side in the front-rear direction of the vehicle has the weakened portion having a small thickness, and the weakened portion is liable to break when receiving the impact force to tilt the knuckle backward, and further the lower arm is liable to disengage from the knuckle, and further the front wheel connected to the lower arm can be moved to the outside in the width direction of the vehicle, so that the front wheel is prevented from being pressed at the time of collision to transmit the impact force to the vehicle body frame in a large amount. Further, the connecting rib is formed to have a large thickness, and the rigidity of the knuckle can be increased. Thus, the knuckle of the vehicle of the utility model has good rigidity and can reduce the impact force transmitted to the body frame at the time of collision.
In order to make the above features and advantages of the present utility model more comprehensible, embodiments accompanied with figures are described in detail below.

Detailed Description
Fig. 1 is a perspective view of a knuckle of a vehicle in which an axial direction X, Y, Z is shown, according to an embodiment of the utility model. Fig. 2 is a perspective view of the knuckle of fig. 1 from another perspective. Referring to fig. 1 and 2, the knuckle 100 of the present embodiment includes a main body portion 110, a damper connecting portion 120, an arm portion 130, and a lower arm connecting portion 140. The main body 110 supports an axle. The damper connecting portion 120 is located closer to the center of the vehicle in the width direction (i.e., the direction parallel to the axial direction X) than the main body portion 110, and serves to fix the damper. The arm portion 130 connects the outer peripheral portion 1201 of the body portion 110 and the damper connecting portion 120. The lower arm connecting portion 140 is located at the lower end of the body portion 110 and serves to connect a lower arm that is connected to the front wheel of the vehicle.
In detail, the arm 130 includes a first arm 132, a second arm 134, and a connection rib 136. The first arm 132 is located on the front side of the second arm 134 in the front-rear direction of the vehicle (i.e., the direction parallel to the axial direction Y), and the connecting rib 136 is located at the lower end of the damper connecting portion 120 and connects the first arm 132 and the second arm 134.
Fig. 3 is a side view of the knuckle of fig. 1. Fig. 4 is a partial front view of the knuckle of fig. 1. In the present embodiment, the second arm portion 130 has a weakened portion 1341 at a position closer to the main body portion 110 than the connection rib portion 136. As shown in fig. 3, the width W2 of the weakened portion 1341 is smaller than the width W1 of the first arm 132. As shown in fig. 4, the thickness T1 of the connection rib 136 is greater than the thickness T2 of the weakened portion 1341.
As described above, in the knuckle 100 of the vehicle of the present embodiment, the second arm portion 134 located on the rear side in the front-rear direction of the vehicle (i.e., the direction parallel to the axial direction Y) has the weakened portion 1341 having a small thickness, and the weakened portion 1341 is liable to break when receiving the impact force to tilt the knuckle 100 backward, and further the lower arm is liable to disengage from the knuckle 100, and further the front wheel connected to the lower arm can be moved to the outside of the vehicle in the width direction (i.e., the direction parallel to the axial direction X) to avoid the front wheel from being pressed at the time of collision to transmit the impact force to the vehicle body frame in a large amount. Further, the connection rib 136 is formed to have a large thickness, and the rigidity of the knuckle 100 can be increased. Thus, the knuckle 100 of the vehicle of the present embodiment has good rigidity and can reduce the impact force transmitted to the vehicle body frame at the time of collision.
The knuckle 100 of the present embodiment further includes a brake caliper connecting portion 150, the brake caliper connecting portion 150 being located on a front side of the main body portion 110 in a front-rear direction of the vehicle (i.e., a direction parallel to the axial direction Y) and being configured to connect a brake caliper. Further, the knuckle 100 of the present embodiment further includes a tie rod attachment portion 160, the tie rod attachment portion 160 being located on the rear side of the main body portion 110 in the front-rear direction of the vehicle (i.e., the direction parallel to the axial direction Y) and being used to attach a tie rod.
As described above, in the knuckle of the vehicle of the present utility model, the second arm portion located on the rear side in the front-rear direction of the vehicle has the weakened portion having a small thickness, and the weakened portion is liable to break when receiving the impact force to tilt the knuckle backward, and further the lower arm is liable to disengage from the knuckle, and further the front wheel connected to the lower arm can move to the outside in the width direction of the vehicle, so that the front wheel is prevented from being pressed at the time of collision to transmit the impact force to the vehicle body frame in a large amount. Further, the connecting rib is formed to have a large thickness, and the rigidity of the knuckle can be increased. Thus, the knuckle of the vehicle of the utility model has good rigidity and can reduce the impact force transmitted to the body frame at the time of collision.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced with equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
