Abstract

(57) [Summary] [Purpose] The objective is to remove ice and snow adhering to the inner surface of the outer periphery of the disc wheel when running on a snowy road with a steering knuckle. [Structure] A steering knuckle 1 is provided with a connecting arm 8 for connecting struts 13 and the like of a suspension device, and the connecting arm 8 is provided with a protrusion 21 projecting toward an inner peripheral surface 7a of an outer periphery of a disc wheel 7. ..

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a steering knuckle that supports steering wheels of an automobile.

[0002]

[Prior art]

 Generally, a steering knuckle for supporting a steering wheel of an automobile is provided with a plurality of connecting arms from a knuckle body and a strut or a lower arm of a suspension device or a tie rod of a steering device is provided on the connecting arms, as described in Japanese Utility Model Laid-Open No. 2-21181-1. And the brake caliper is installed.

[0003]

[Problems to be solved by the device]

 By the way, when traveling on a snowy road in winter, ice and snow adhere to the inner peripheral surface of the disc wheel, which accumulates and interferes with the connecting bolts of the brake hose located near the disc wheel. An object of the present invention is to provide a steering knuckle capable of removing ice and snow adhering to the disc wheel as described above.

[0004]

[Means for Solving the Invention]

 In order to achieve the above-mentioned object, the present invention is a steering knuckle provided with a connecting arm for connecting a strut, a lower arm, etc. of a suspension system. In the outer peripheral inner surface of a disc wheel of a wheel located outside the steering knuckle on the connecting arm. It is provided with a protrusion protruding toward.

[0005]

[Action]

 When ice and snow that adheres to the inner surface of the disc wheel accumulates to a certain extent, it is scraped off by the protrusions of the suaring knuckle to prevent further adhesion, and parts such as connecting bolts for the brake hose located closer to the center of the disc wheel than the protrusions are attached. Interference with ice and snow is prevented.

【Example】

 1 and 2 are a front view and a side view showing a mounting state of a steering knuckle in a front-wheel drive vehicle. In the figure, reference numeral 1 is a steering knuckle, 2 is a drive shaft that penetrates the steering knuckle 1 and is supported by the steering knuckle 1 by a bearing 3, and a wheel hub 4 is spline-fitted to the tip thereof. A brake rotor 5 is attached to the inside of the wheel hub 4, and a disc wheel 7 of a wheel 6 is attached to the outside of the wheel hub 4 with bolts 22 and 23, respectively. A dust cover 24 is attached to the inside of the rotor 5.

As shown in FIG. 2, the steering knuckle 1 is provided with connecting arms 8, 9, 10, 11, 12 extending in four directions, and the connecting arm 8 extending upward is provided with a shock absorber strut. The lower end of 13 is attached, and 14 is a bolt hole for the attachment. The lower arm 15 of the suspension is connected to the connecting arm 9 extending downward, the tie rod (not shown) of the steering is connected to the connecting arm 10 extending rearward, and the caliper 16 of the brake is connected to the connecting arms 11 and 12. It is attached by bolt 17. A cylinder 18 is attached to the caliper 16, and a brake hose 19 is connected to the cylinder 18 with a union bolt 20.

At the tip of the connecting arm 8 to which the shock absorber strut 13 is attached, a projection 21 projecting toward the inner peripheral surface 7 a of the disc wheel 7 is integrally formed. The distance L between the protrusion 21 and the outer peripheral inner surface 7a of the disc wheel 7 is set to be shorter than the distance between parts such as the union bolt 20 attached to the steering knuckle 1. In the above configuration, ice snow S adheres to the outer peripheral inner surface 7a of the disc wheel 7 when traveling on a snowy road, but when the ice snow S accumulates in a certain amount or more, it is scraped off by the protrusions 21 as the wheel 1 rotates, and more Adhesion is prevented. In the above embodiment, the projection is integrally formed with the connecting arm 8 for connecting the shock absorber struts 13, but the present invention is not limited to this, and it may be provided on another connecting arm, for example. Alternatively, the protrusion may extend from the mounting bracket of the shock absorber strut that is bolted to the connecting arm 8 instead of being integral.

[0009]

[Effect of device]

 As is clear from the above description, according to the present invention, even if ice and snow adheres to the inner surface of the outer periphery of the disc wheel while traveling on a snowy road, the snow is removed by the protrusions provided on the steering knuckle, so the ice and snow is braked. It does not interfere with the connection bolt of the.
