Description

Steering knuckle

Technical Field

The utility model relates to the field of vehicle parts, in particular to a steering knuckle.

Background

The steering knuckle is an important part in a front axle system of a vehicle, the steering knuckle is used for enabling the vehicle to stably run and transmitting the running direction, and the main functions of the steering knuckle are as follows: the front load of the vehicle is transferred and borne, and the front wheels are supported and driven to rotate around the pin shafts so as to steer the vehicle. In the process of rotating the existing knuckle around a pin shaft, the rotatable angle of the knuckle is not limited, and the situation that the front wheel of a vehicle rotates due to the fact that the knuckle rotates excessively can occur, so that serious accidents are caused.

Detailed Description

Embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 5, the present utility model provides a steering knuckle, which comprises a steering knuckle body 1, the steering knuckle is an integrated structure, the steering knuckle body 1 is sequentially provided with a rotating pipe, a transition pipe and a steering joint from left to right, the transition pipe is obliquely arranged from right to left, the wall thickness of the transition pipe is gradually increased from right to left, the inner wall and the outer wall of the transition pipe are in seamless connection with the rotating pipe and the inner wall and the outer wall of the steering joint, a pin shaft is connected at a pin shaft hole, the steering knuckle rotates around the pin shaft hole, the steering joint is connected with a front shaft to steer with a hub, the left end of the rotating pipe is provided with a groove forming an up-down symmetrical rotating lug 2, the rotating lug 2 is vertically provided with a pin shaft hole 3, the pin shaft hole is connected with a pin shaft, the lower ends of the rotating pipe and the transition pipe are longitudinally provided with a connecting strip 4, the lower ends of the connecting strip 4 are symmetrically provided with a first limiting block 5 from front to back, the middle of the top end of the transition pipe is provided with a second limiting block 6, the steering knuckle rotates excessively easily in the process of rotating around the pin shaft, when the steering knuckle rotates around the pin shaft, the first limiting block rotates correspondingly, the steering knuckle rotates to a certain angle, the steering knuckle rotates correspondingly, the steering knuckle is prevented from rotating around the limiting block, and the other limiting blocks are prevented from rotating around the steering.

In order to accurately control the rotatable angle, a notch 6.1 is formed in the upper side of the rear end of the second limiting block 6. The notch is the butt department as the second stopper, and the notch is through precision finishing to can effectively guarantee the degree of accuracy that rotates the definition, prevent to rotate excessively, the left and right sides terminal surface of first stopper also is the butt department and through precision finishing.

The strengthening rib both can strengthen the intensity of rotation pipe, transition pipe junction, can promote the intensity of the one section that the connecting strip extends away again, is provided with strengthening rib 7 between connecting strip 4 and rotation pipe, the transition pipe for the knuckle rotates in place, and first stopper butt can force transfer to the connecting strip, and the connecting strip is difficult for fracture and deformation.

Through protruding, the round platform enhances the structural strength of corresponding department, is difficult for taking place to fracture and warp, and the lower extreme that the downside rotated ear 2 transversely is provided with connect connecting strip 4 and is banding protruding 8, and protruding setting can strengthen the downside and rotate the intensity of ear, at the in-process that rotates ear connecting pin axle and pivoted, can bear radial stress, rotates ear 2 and is provided with the round platform that sets up with the coaxial line of round pin axle hole 3 in one side of keeping away from the recess. The round platform sets up the area of contact that has increased round pin axle hole and round pin axle for rotate and connect more stably, strengthened the intensity of this department moreover, be difficult for taking place the fracture.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several modifications and variations can be made without departing from the technical principle of the present utility model, and these modifications and variations should also be regarded as the scope of the utility model.
