Description
[technical field]
The utility model is about a kind of engine continuous variable speed transmission case structure, particularly about reducing manufacture cost and avoiding the not good structure of transmission-case cover aesthetic appearance.
[background technique]
Motorcycle is with the advantage of its flexibility, and by the glad means of transportation that is used as working of people, and wherein scooter motorcycle is owing to have the operation ease of continuous variable speed, and the outward appearance of novel moulding, and its occupancy is improved every year.
Generally with regard to the scooter motorcycle engine structure, see also shown in Figure 1, it is to establish a transmission case 2 at the side of engine 1, this transmission case 2 has a transmission-case cover 21, be provided with belt speed change mechanism 3 in the transmission case 2, behind the oil gas input engine 1 of blend gasoline and air, promptly make oil gas fire by ignition mechanism 11 igniting, and it is reciprocating to promote piston 12, and the bent axle 13 of drive and its binding, 13 on bent axle stretches into transmission case 2 inside with axle 14 and links with belt speed change mechanism 3, and drive the rotation of trailing wheels through belt speed change mechanism 3, trailing wheel drives front-wheel again and rotates synchronously, to reach the purpose of advancing, this belt speed change mechanism 3 is provided with a slider disc 31 and a drive plate 32 in axle 14, these drive plate 32 1 sides are provided with a wind deflector 30, the right side of this slider disc 31 utilizes a limiting board 33 to limit a ball 34 location, 32 of this slider disc 31 and drive plates are arranged with a drivign belt 35, the end in addition of this drivign belt 35 then is sheathed on the driven disc 36 of opposite side, and a driven disc 36 and a final gear train 37 link.
When bent axle 13 the axle 14 by piston 12 driven rotary after, this slider disc 31 and drive plate 32 promptly are driven in rotation, when the knight opens the throttle, this rotating speed of 14 improves immediately, and ball 34 is subjected to the influence of centrifugal force to rising, and make and promote slider disc 31 transverse shift to the left, and then make the two pitch smaller of slider disc 31 and drive plate 32, and the circumference that makes drivign belt 35 rotate strengthens, so the rotating speed of other side driven disc 36 also thereby accelerate, drive the rotation of back crop rotation higher speed, to reach the purpose of acceleration.
Because the belt speed change mechanism 3 in the transmission case 2 can produce high temperature under the running of high speed rotating and engine 1, therefore in order to reduce the temperature in the temperature transmission case 2, general existing transmission case 2 can be offered an air inlet 22 in front side end, this air inlet 22 connect establish a reelability conduit 23, so as to introducing extraneous cool air, carry out the work of cooling, this transmission-case cover 21 then is provided with an exhaust outlet 24 in addition, by being provided with of this exhaust outlet 24 cooling air is discharged.
Please cooperate Fig. 2 to consult; the exhaust outlet 24 of this transmission-case cover 21 is when making; discharge smoothly in order to make the cooling air air-flow; therefore be below being arranged in the middle of the transmission case; and form the position and the height requirement of this exhaust outlet 24 with the mould of vertical slipper; make this drive plate 32 when cool air is imported; can flow to driven disc 36 via exhaust outlet 24 belows earlier; with clockwise around after discharge by exhaust outlet 24 again; to avoid causing the sinuous flow of cooling air; improve radiating efficiency simultaneously, yet because the wall thickness of these exhaust outlet 24 shaping positions is thicker, and for when the demoulding is shaped; avoid causing in this place's generation and contract; waste of material and cool time are long; usually can cut several groove 211, as shown in Figure 3 in the surface of transmission-case cover 21; the thickness of wall thickness that reduces exhaust outlet 24 is to overcome above-mentioned problem; but also caused the not good disappearance of these transmission-case cover 21 aesthetic appearance, and, also increased the fabricating cost of this transmission-case cover 21 in addition with slide block mould this exhaust outlet 24 that is shaped.
Because the transmission-case cover 21 of existing transmission case 2 has above-mentioned disappearance, so, develop the transmission case that can reduce manufacture cost and also can promote aesthetic appearance, in fact the problem of demanding urgently overcoming for present motorcycle manufacturer.
