There are two types of overrunning clutch(one-way clutch), Wedge Type and Roller Type, and which one is more suitable for tricycles? Tricycles are usually used for heavy loading jobs, for cargos or for passengers. Thus, it is believed the Roller type, which is of simple-structured, more tolerant to machining accuracy level and 360 degree rotating, is more stable and of longer lifespan than the Wedge Type, which is of tilting type, and requires higher machining and assembling accuracy.

1. Roller Type Overrunning Clutch

3 Rollers: good for power under 150cc

6 Rollers: good for power 150-200cc(under)

9 Rollers: good for power 150-250cc(included)

The malfunction of this type of overrunning clutch mainly comes from:

1. Failure of Spring: due to the backlash force and the high temperature
2. Abrasion of Roller: the friction shrink the roller’s diameter(however, if the shrink is within 0.05mm, it can still work)

2. Wedge Type Overrunning Clutch

16 Wedges, 18 Wedges, 20 Wedges

The Stuck of this type of overrunning clutch mainly comes from:

1. Uneven abrasion among wedges
2. Abrasion of Wedges
3. Spring Breakup

3. Comparison Between Two Types of Overrunning Clutches

4. Conclusion

With lower expense and higher accountability, it is suggested to use Roller Type Overrunning Clutches on tricycles, especially the high-displacement(over 200cc) tricycles.

The meaning of the symbols in the table:

I: To Check, Clean, Adjust, Lubricating or Replace

C: Clean

R: Replace

L: Lubricating

Note:

Note 1: After the odometer figure is over the max figure in the table, Please still repeat the maintenance based on the same interval period.

Note 2: In the dusty area, please clean it more often.

Note 3: Only for Drving Shaft type vehicle, for Drving Chain type, refill with universal lithium base grease for every 1000km (620 miles) driving.

 

 

Along with the booming of online purchase, the industry of express post also rises swiftly. As the current most suitable terminal delivery tools, many delivering–electric tricycles (three wheelers) were modified from the agricultural and passengers types, and the lack of tech performance standards leads to the poor safety, illegalized identity and government’s forbid.

Recently, Jiangsu Province is implementing the unified management to the delivering-electric tricycles (three wheeler) from the aspects of appearance, registration, driving license acquiring, commuting route, temporary parking. The Express companies actively accelerate the upgrade of  terminal delivering—electric tricycles (three wheelers), centrally purchasing the electric tricycles (three wheelers) which accord with the nation’s tech standards, and the road transportation administers also offer good services to facilitate the registration, driving license acquiring, commuting route and temporary parking.

It means the delivering-electric tricycles (three wheelers) forbidden to ride on the road previously now acquire a legalized identity. They can run on the city roads legally as long as they meet the relevant regulations with “unified vehicle standards, unified appearance, unified code system, unified insurance, unified safety training, unified platform management”.

Jiansu Province is not the only one to do this, other provinces like Liaoning is also doing the similar things. It is believed that with the regulations implementing, the legalization of delivering-electric tricycles (three wheelers) will cover more regions nationwide, which will bring more stable markets for electric tricycle industry.

In recent years, electric tricycles have developed rapidly, and their popularity has increased by one year. However, when purchasing electric tricycles, many users still have this question: so many tricycles, how to choose configuration?

In fact, for this issue, you only need to take a look at the following five accessories to judge the pros and cons.

First of all, the first thing to look at is the motor and battery. As the two core parts of the electric tricycle, its quality directly affects the performance of the electric tricycle. Take the battery as an example. The larger the capacity, the longer the battery life of the electric three wheeler, and the smaller the capacity, the shorter electric tricycle battery life is shorter.
In addition, the battery brand is also very important. Generally speaking, high-quality electric three wheeler will use first- and second-tier batteries in the industry, which not only guarantees after-sales service, but also has better battery life and performance.
Whether it is a tricycle or a two-wheeled vehicle, the high-quality electric vehicle frame is relatively strong. If you are a novice, you can look at the thickness of the pipe and choose a relatively thick one. Generally speaking, the thicker the pipe, the better the quality of the frame. Of course, the heavier the electric three wheeler is and the better the quality.
The quality of the frame is not only related to the load-bearing capacity of the entire electric three wheeler, but also directly determines the safety of the whole vehicle. Inferior frames often have insufficient load-bearing capacity and are more likely to break. There is a high safety hazard and a high probability of accidents. Be sure to pay more attention when purchasing.
For headlights, high-quality electric three wheelers will use lens LED headlights, which can illuminate longer and brighter at night, while inferior electric three wheeler will only use ordinary headlights, which are not only not bright enough, but also easy to appear. Failure, changing the lamp back and forth is time-consuming and costly.
