Abstract
The utility model relates to the technical field of the electric motorcycle component, particularly to a steel rim and motor housing assembly for an electric motorcycle. The utility model comprises a steel rim and a radial plate, wherein the steel rim is fixed with the radial plate which is fixed with a motor housing, the motor housing and an end cap at one side are a whole, and the radial plate is composed of a plurality of single radial plates. The assembly has the advantages of good integrality, weight reduction, great cost reduction, convenient and labor-saving installation, small processing amount and material consumption reduction. Because of the high utilizing rate of the magnetic loop of a motor magnetic field, the motor force is increased, and the service life is prolonged. The radial plate is changed from a whole into a plurality of single radial plates and can use leftover bits and pieces, so the material cost is saved.
Description
Affiliated technical field
The utility model relates to battery-operated motor cycle accessory technical field, especially a kind of electric motorcycle steel ring and motor casing unit assemblage.
Background technology
At present, the structure of its steel ring of the battery-operated motor cycle of Shi Yonging and motor casing unit assemblage is at home: steel ring has two kinds on aluminum-rim and plate system steel ring, wherein plate system steel ring is that the steel plate roll extrusion forms, the disc that connects between steel ring and the motor housing is that integral body is stamped to form, the motor housing employing is watered steel and is made, add a cover the bearing support end cap at the motor housing two ends, its shortcoming is to water the steel heaviness, processing capacity is big, waste material is many, and main problem is to water the low carbon content that steel requires to be difficult to guarantee that the magnetic field magnetic loop degree of utilization of Chan Shenging is good inadequately like this, motor strength is lossy, and influences service life.
The utility model content
In order to overcome the deficiency of existing electric motorcycle steel ring and motor housing, the utility model provides a kind of in light weight, laborsaving electric motorcycle steel ring of process and assemble and motor casing unit assemblage.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of electric motorcycle steel ring and motor casing unit assemblage, comprise steel ring, disc, steel ring and disc are fixed, and disc and motor housing are fixed, and it is characterized in that: a motor housing and a side end cap are single-pieces.
The material of a described single-piece motor housing and a side end cap is the following mild steel plates of No. 10 steel of carbon content.
Described disc is made up of some monomer disc.
The beneficial effects of the utility model are: an integrated electric motor shell and a side end cap that mild steel plate stretches and makes, good integrity, expendable weight, cost-cutting significantly, process and assemble is convenient and strength-saving, and motor-field magnetic loop degree of utilization height has improved motor strength and service life; Disc changes some into by integral body, can use leftover pieces, has saved material cost.
Description of drawings
