Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1 and Figure 2, the belt wheel of this stepless transmission includes driving wheel 1 and driven wheel 2, and driving wheel 1 is for connecting
Driving shaft 3, driving wheel 1 and driven wheel 2 include two pieces of adjustable berths away from tep reel 4, have for transmission belt between two pieces of tep reels 4
5 troughs of belt 6 being caught in, at least one piece of tep reel 4 have multi-disc radiator shutter 7 far from the side of trough of belt 6.
It further describes in detail, the arc-shaped sheet of radiator shutter 7 and circumferentially array distribution, multi-disc radiator shutter 7 is around shape
At air collecting chamber 8, airflow channel 9 is formed between two panels radiator shutter 7, cross-sectional area is gradually increased airflow channel 9 from inside to outside.
Preferably, radiator shutter 7 is set on the tep reel 4 in addition to the tep reel 4 close to 3 side of driving shaft.Due to master
Driving wheel 1 needs firmly to connect with driving shaft 3, therefore, is often additionally provided on the tep reel 4 of 3 side of driving shaft a large amount of
Reinforcing rib 13, i.e., remaining space is less, and if radiator shutter 7 is set on the tep reel 4 of the side, heat dissipation effect is not provided with
Good heat dissipation effect on other three pieces of tep reels 4.
Preferably, radiator shutter 7 is only arranged on the tep reel 4 on driving wheel 1 far from 3 side of driving shaft.The band of the side
There is more space on disk 4, and connect with driving shaft 3, power abundance will not influence the transmitting of kinetic energy, and if be set to from
On the tep reel 4 of driving wheel 2, it is easy to increase the weight of driven wheel 2, increases the loss of kinetic energy, influence the transmitting of kinetic energy.And driving wheel 1
The heat of side is often more than the heat that 2 side of driven wheel generates, and radiator shutter 7, which is set to the side also, can play better dissipate
Thermal effect.
