Description
Technical Field
The utility model relates to a steel bowl assembly, in particular to a structure of a front fork steel bowl assembly of a battery car bicycle.
Background
At present, steel bowl assemblies of battery cars and bicycles are continuously innovated, so that not only is the product performance improved, but also the cost is reduced and the production benefit is improved, a front fork steel bowl assembly in the prior art is mainly composed of an upper steel bowl assembly and a lower steel bowl assembly, the steel bowl assembly is composed of a steel bowl and a bearing, the bearing is placed in the steel bowl, a developed drawing (the bearing is 1, the steel bowl is 2) is shown in figure 1, or a steel ball and a ball frame are adopted to replace the bearing and save an outer ring, the two structural modes have lower requirements on the steel bowl and the steel ball material, the battery cars and the bicycles are developed to high grade at present, once the steel bowl and the steel ball material are made of high-carbon steel, the outer ring of the bearing can be saved, the ball frame of the steel ball can also be saved, the requirements can be met, and a plurality of schemes can be generated by innovating on the structure.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a material-saving front fork steel bowl assembly structure of a battery car bicycle, wherein a steel bowl is internally provided with no bearing and is only provided with a steel ball, so that the product cost is reduced, and the production efficiency is improved.
In order to solve the technical problems, the utility model adopts the following scheme: the utility model provides a structure of front fork steel bowl subassembly of storage battery car bicycle of province material, by last shelves, aluminium opening, go up steel bowl subassembly, steel bowl subassembly and shelves are constituteed down, goes up the shelves on the aluminium opening, and the aluminium opening is on last steel bowl subassembly, goes up steel bowl subassembly and is mouthful on bicycle front fork riser, and lower steel bowl subassembly is mouthful under bicycle front fork riser, has down shelves, its characterized in that below the lower steel bowl subassembly: the upper steel bowl assembly and the lower steel bowl assembly are composed of a steel bowl, a steel ball group, an inner gear, a small sealing ring and a large sealing ring, the steel ball group, the inner gear and the large sealing ring are sequentially placed in the steel bowl, and the small sealing ring is placed in the reverse side of the steel bowl.
The steel ball group is composed of 5/32〃And 28 steel balls.
The small sealing ring and the large sealing ring enter the steel bowl through a pressing-in method.
The utility model has the beneficial effects that: because the bearing outer ring (or the ball frame) in the prior art is omitted, the metal material cost for manufacturing the bearing outer ring (or the ball frame) and the production cost for processing the outer ring (or the ball frame) are saved, and the production benefit is improved.
