Specifically, the avoiding groove 23 is formed in a ring shape, and after the damping post 10 is arranged in the mounting hole 22 of the mounting portion 21, the avoiding groove 23 can be made to surround the damping post 10 in the circumferential direction, so that the portions, located on two sides of the avoiding groove 23, of the mounting hole 22 are in circumferential contact fit with the damping post 10, and therefore the strength of mutual connection fit between the damping post 10 and the steering knuckle 20 can be further improved.
As shown in fig. 3, the height of the avoiding groove 23 is h, and h satisfies the relation: h is more than or equal to 20mm and less than or equal to 40 mm. Specifically, the height of the avoiding groove 23 is within a reasonable range, and the height of the avoiding groove 23 can be selectively adjusted within the reasonable range according to specific process requirements on the premise that the inner side wall of the mounting hole 22 is located on the two sides of the avoiding groove 23 and the damping column 10 to be stably and reliably contacted, so that the requirement for meeting different steering knuckle assemblies 100 is met by the avoiding groove 23, and the applicability of the avoiding groove 23 can be improved.
Further, as shown in fig. 3, the depth of the avoiding groove 23 is d, and d satisfies the relation: d is more than 0 and less than or equal to 2 mm. Specifically, the degree of depth that will dodge groove 23 sets up at reasonable within range, not only can prevent to dodge the degree of depth undersize of groove 23, lead to the mounting hole 22 to be located and dodge groove 23 both sides only less part can closely cooperate with damping post 10, and also can prevent to dodge groove 23's degree of depth too big, lead to the mounting hole 22 to be located and dodge the cooperation of the part of groove 23 both sides and damping post 10 unstable, the part that mounting hole 22 is located and dodge groove 23 both sides is easy to take place deformation, cause the structural damage of installation department 21, can promote knuckle 20 and damping post 10 stability and reliability of mutually supporting like this.
Further, the number of the avoiding grooves 23 in the mounting hole 22 may be one or more, and a plurality of the avoiding grooves 23 are provided at intervals in the axial direction of the mounting hole 22. Specifically, the number of the avoiding grooves 23 can be selectively set according to the height of the mounting hole 22, the height of the lower end of the damping column 10 and the height of the avoiding grooves 23, so that the damping column 10 is stressed more uniformly in the mounting hole 22, and the stability and reliability of the mounting arrangement of the damping column 10 in the mounting hole 22 can be further improved.
As shown in fig. 2 and 3, the inner side wall of the mounting hole 22 is formed at an upper portion with an upper fitting surface 24 and at a lower portion with a lower fitting surface 25, and the upper fitting surface 24 and the lower fitting surface 25 have the same height. Specifically, the upper fitting surface 24 and the lower fitting surface 25 on the inside wall of the mounting hole 22 are respectively located at the upper side and the lower side of the avoidance groove 23, the upper fitting surface 24 and the lower fitting surface 25 can be matched with the damping column 10 in a squeezing contact manner, the upper fitting surface 24 and the lower fitting surface 25 are arranged at the same height, the upper and lower stress of the damping column 10 can be more uniform, the fitting height of the damping column 10 in the mounting hole 22 can be increased, and the reliability of the knuckle assembly 100 can be further improved. The height of the shock absorbing column fitted to the mounting portion is the length from the upper end of the upper fitting surface to the lower end of the lower fitting surface.
As shown in fig. 3 and 4, the fastening member 30 is correspondingly disposed at the middle portion of the outer side wall of the mounting portion 21 and corresponds to the outer side of the escape groove 23. Specifically, correspond fastener 30 and set up behind the middle part of the lateral wall of installation department 21, can make fastener 30 correspond in the outside of dodging groove 23, so set up, after fastener 30 fastens installation department 21, can make the power that the both sides of fastener 30 received evenly equal, can make the fastening power of fastener 30 that upper fitting surface 24 and lower fitting surface 25 received evenly equal, can further guarantee like this that upper fitting surface 24 is the same with lower fitting surface 25 to the extrusion contact mating reaction of damping post 10, can make the atress of damping post 10 more even, thereby can further promote stability and the fastness that damping post 10 installed the setting in mounting hole 22. The fastening member 30 may be a bolt, and the bolt may circumferentially bolt the mounting portion 21, so that the inner sidewall of the mounting hole 22 is circumferentially press-fitted to the damping post 10.
As shown in fig. 2 and 3, the lower end of the mounting hole 22 is provided with a stopper 26 protruding radially inward, and the lower end surface of the damping post 10 is fitted with the stopper 26. Specifically, the stopping portion 26 may be matched with the lower end surface of the damping pillar 10, so as to limit the downward displacement of the lower end surface of the damping pillar 10, and further, to more comprehensively improve the stability and firmness of the installation and setting of the damping pillar 10 in the installation hole 22.
Further, as shown in fig. 3 and 4, the upper end of the mounting hole 22 is provided with a chamfer 27.
