Abstract
An assemblage of rim and motor casing for electric motorcycle is composed of steel rim and web consisting of several web units and fixed to the casing of motor. Its manufacture includes such steps as rolling steel plate to form steel rim, punching on steel plate to obtain web units, welding the web units to steel rim, and connecting the flange of motor casing with web via screw bolts.
Description
Affiliated technical field
The present invention relates to battery-operated motor cycle accessory technical field, especially a kind of electric motorcycle steel ring and motor casing unit assemblage and manufacture method.
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 support of bearing 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 utilization rate of Chan Shenging is good inadequately like this, motor strength is lossy, and influences service life.
Summary of the invention
The objective of the invention is on the basis of original electric motorcycle steel ring and motor casing unit assemblage, provide a kind of in light weight, simple electric motorcycle steel ring of process and assemble and motor casing unit assemblage; For this reason, the present invention also will provide a kind of method of making this electric motorcycle steel ring and motor casing unit assemblage.
Technical solution of the present invention is: a kind of electric motorcycle steel ring and motor casing unit assemblage, comprise steel ring, disc, and 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 whole.
The material of the motor housing of described integral body and a side end cap is the following low carbon steel plates of No. 10 steel of phosphorus content.
Described disc is made up of some monomer disc.
Manufacture method of the present invention comprises the steps: respectively the steel plate roll extrusion to be become steel ring earlier, steel plate is struck out disc, again with disc by on the inner ring that is welded on steel ring, motor housing ring flange and disc thread connection, it is characterized in that: motor housing makes by following processing step, with No. 10 low carbon steel plates below the steel of phosphorus content, after the blanking, again through dash/press pulls at mould and is stretched into shape, respectively flange surface, bearing mounting hole, magnet steel placed side and the shell end face that contacts with disc carried out metal cutting fine finishining then.
Advantage of the present invention is: an integrated electric motor shell and a side end cap that low carbon steel plate stretches and makes, and good integrity, weight reduction reduces cost significantly, and process and assemble is convenient and strength-saving, and motor-field magnetic loop utilization rate 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
Fig. 1 is a cross-sectional view of the present invention;
Fig. 2 is Fig. 1 left view.
1. bolts among the figure, 2. spring washer, 3. disc, 4. steel ring, 5. nut, 6. motor housing.
The specific embodiment
In Fig. 1, Fig. 2,5 disc (3) are uniform to be welded on the steel ring (4), a motor housing and a side end cap are whole, and the opening end of motor housing (6) has the ring flange that turns up, and disc (3) is fixing with bolt (1), spring washer (2) and nut (5) with the ring flange of motor housing (6).Motor housing (6) forms for low carbon steel plate stretches, and disc (3) is stamped to form for steel plate.At the opening end of motor housing (6) bearing bracket end lid or brake rim can be installed as required.
As Fig. 1, shown in Figure 2, respectively steel plate spinning is become earlier steel ring (4), steel plate is struck out disc (3), again with disc (3) by on the inner ring that is welded on steel ring (4), motor housing (6) ring flange and disc (3) bolt (1), spring washer (2) and nut (5) thread connection are fastening, motor housing (6) is the following low carbon steel plates of No. 10 steel of phosphorus content, specific to present embodiment is the 08F steel plate, after the blanking, again through dash/press pulls at mould and is stretched into shape, the flange surface to contacting with disc (3) respectively then, bearing mounting hole, magnet steel placed side and shell end face carry out metal cutting fine finishining.
Claims (4)
1. electric motorcycle steel ring and motor casing unit assemblage comprise steel ring, disc, and 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 whole.
2. according to described electric motorcycle steel ring of claim 1 and motor casing unit assemblage, it is characterized in that: the material of the motor housing of described integral body and a side end cap is the following low carbon steel plates of No. 10 steel of phosphorus content.
3. according to described electric motorcycle steel ring of claim 1 and motor casing unit assemblage, it is characterized in that: described disc is made up of some monomer disc.
4. method of making described electric motorcycle steel ring of claim 1 and motor casing unit assemblage.Earlier respectively the steel plate roll extrusion is become steel ring, steel plate is struck out disc, again with disc by on the inner ring that is welded on steel ring, motor housing flange and disc thread connection, it is characterized in that: motor housing makes by following processing step, with the following low carbon steel plate of No. 10 steel of phosphorus content, after the blanking, again through dash/press pulls at mould and is stretched into shape, respectively flange face, bearing mounting hole, magnet steel placed side and the shell end face that contacts with disc carried out metal cutting fine finishining then.
