Description

Technical Field

[0001] The utility model relates to the field of loaders, in particular to a steering wheel hub stone baffle device on a loader. Background Art

[0002] When the loader is actually shoveling stones, there is a gap between the tire hub and the vehicle, and the splashing stones are easy to get stuck in this gap. Due to the instability of stones or the bouncing of shoveling, stones are easy to splash into the steering hub and cause jamming. During operation, the driver is not easy to notice because the cab is at a high position. After the stone is stuck, it rotates through the steering hub. The excessive stress will damage the hydraulic oil pipe and bracket of the hub accessories, causing greater losses. Utility Model Content

[0003] The utility model aims to provide a steering wheel hub stone blocking device on a loader, which can not only not affect the actual operation but also block the stones splashing during the work.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model provides a steering wheel hub stone guard device on a loader, which is installed between the tire hub and the loading arm, including an inner layer bellows, an outer layer bellows partially sleeved on the inner layer bellows, and a rolling bearing arranged between the inner layer bellows and the outer layer bellows.

[0005] Preferably, the end of the outer layer corrugated tube away from the inner layer corrugated tube is provided with a front end flange and a front end bolt for connecting to the tire hub.

[0006] Preferably, the end of the inner layer bellows away from the outer layer bellows is provided with a rear end flange and rear end bolts for connecting the loading arm.

[0007] Preferably, the outer layer corrugated tube and / or the inner layer corrugated tube are / is made of a flexible and retractable steel wire braided tube.

[0008] Preferably, the outer layer bellows and / or the inner layer bellows are made of stainless steel 316Ti.

[0009] Preferably, the outer surface of the outer layer corrugated tube and / or the inner layer corrugated tube is provided with protrusions for resisting stones.

[0010] In summary, the utility model includes the following beneficial technical effects:

[0011] The utility model installs a flexible and retractable steel wire braided tube between the steering tire side and the loading arm to resist flying stones without damaging the own pipeline and the bracket and causing jamming. It can not only not affect the actual operation but also block the flying stones during the work. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1 As shown in the circle, there is a gap between the wheel hub of the existing loader and the entire vehicle, which makes it easy for stones to get stuck.

[0019] The utility model discloses a steering wheel hub stone blocking device on a loader, which can be installed between a tire hub 1 and a loading arm 10 to resist flying stones without damaging its own pipelines and brackets and causing jamming. It can not only not affect actual operations, but also block flying stones during work.

[0020] The utility model includes an inner layer bellows 7 which can be installed on a loading arm 10, and an outer layer bellows 4 which can be installed on the inner side of a tire hub 1. The end of the outer layer bellows 4 close to the loading arm 10 is sleeved on the outer periphery of the end of the inner layer bellows 7 close to the tire hub 1, and a rolling bearing is connected between the two ends. The rolling bearing can move in the inner layer bellows 7 to support the inner layer bellows 7 and the outer layer bellows 4 to extend and retract, and the total length of the inner layer bellows 7 and the outer layer bellows 4 can be dynamically adjusted.

[0021] The end of the outer layer bellows 4 away from the inner layer bellows 7 is provided with a front end flange 2 for connecting to the tire hub 1, and the front end flange 2 and the outer layer bellows 4 can be installed on the tire hub 1 through the front end bolts 3. The end of the inner layer bellows 7 away from the outer layer bellows 4 is provided with a rear end flange 9 for connecting to the loading boom 10, and the rear end flange 9 and the inner layer bellows 7 can be installed on the loading boom 10 through the rear end bolts 8.

[0022] The outer layer bellows 4 and the inner layer bellows 7 can be made of flexible and retractable steel wire braided tubes.

[0023] In the utility model, the steel wire braided tube device (inner layer bellows 7, outer layer bellows 4 and rolling bearing) is an integrated component, and the left and right sides are respectively fixed on the tire hub 1 and the loading arm 10 by flange means. When the vehicle is driving in a straight line or turning, it will extend and retract left and right with the action of the rolling bearing, and normal use shall not be affected; and the outer side of the outer layer bellows 4 is a flexible and retractable steel wire braided tube (stainless steel 316Ti), and the protrusions on the surface are used to resist the splashing and adhesion of stones, etc.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
