Protective dismounting equipment for low-flatness-ratio tyre

Abstract

The invention relates to the field of tyre dismounting tools, in particular to protective dismounting equipment for a low-flatness-ratio tyre. The protective dismounting equipment comprises a workbench, a positioning mechanism, an edge holding mechanism and a hydraulic lifting arm, wherein a hydraulic rotary disc is horizontally arranged on the top of the workbench; the positioning mechanism comprises four collision rods and a rotary motor; the outer end of each collision rod is connected with a resisting block; the edge holding mechanism comprises a circular accommodating disc and four holding rods; a pulling disc for pulling the holding rod is arranged in the circular accommodating disc; the side surface of the pulling disc is connected with a pushing rod which extends to the outside ofthe circular accommodating disc; and a plurality of pedal switches are arranged on the bottom of the side of the workbench. The low-flatness-ratio tyre protective dismounting equipment can quickly mount the low-flatness-ratio tyre in a labor-saving mode, avoids the condition that the low-flatness-ratio tyre is damaged as a tyre pressure sensor is collided in a mounting process, and effectively protects a rim from being damaged at the same time.

Description

technical field [0001] The invention relates to the field of tire dismounting tools, in particular to a protective dismounting device for low aspect ratio tires. Background technique [0002] Wheel hub modification refers to the modification of the original wheel hub of the vehicle by the owner or the professional personnel engaged in vehicle modification in order to achieve aesthetics or other purposes. As an important part of the car, the wheel hub and tires are the modification category that many car modification enthusiasts are keen on. , The modification of the wheel hub has gradually become the focus of car fans. The modification of the wheel hub is a more conspicuous modification. From the visual sense, it can be directly judged whether a car has been modified with the hub. Therefore, many people mistakenly think that the upgrade of the hub is not only for Beautiful and eye-catching. In fact, in addition to the aesthetic factors, the modification of the wheel hub can...

In fact, in addition to the aesthetic factors, the modification of the wheel hub can also achieve the purpose of improving heat dissipation and light weight. The modification of the wheel hub generally chooses a larger size hub, and the larger size hub needs to be matched with a tire with a low aspect ratio to ensure that the size of the hub In the case of larger size, the speed per hour is the same as that of the original car, and when the tire with low aspect ratio is assembled with the rim, it is often necessary to remove the tire pressure sensor on the original wheel rim and install it on the new wheel hub, and then install the tire During the process, the inner side of the tire will collide with the tire pressure sensor. At this time, the worker will use a crowbar to insert between the tire and the hub, and then use the hub as a fulcrum to pry the inner edge of the tire to make the inner edge of the tire outside Flip until the tire pressure sensor is out of the way. This process generally requires two to three workers to complete, and it is very laborious. At the same time, the crowbar will damage the paint on the surface of the rim, and in severe cases, the rim itself will be damaged.
