How tricycle motor affects range
During the use of electric tricycles, many users have had this question: tricycle motor of how many wattage should be equipped with electric tricycles to provide sufficient power and the longest range In fact, this issue needs to be discussed in categories.
First, let’s take a look at the main models of electric tricycles, which generally include 48V, 60V, and 72V. Among them, for 48V electric tricycles, the main models are leisure tricycles or small cargo tricycles, and the batteries are generally equipped with models like 48V20Ah and 48V32Ah. So the power and battery life of this type of electric tricycle are relatively moderate.
In order to make electric tricycles have a longer range and take into account power, such models can generally be equipped with 500-600W motors. But generally speaking, if you choose a 500W motor, the 48V electric tricycle has the most power and the longest range.
Let’s look at 60V custom electric tricycle. The main models are medium and large cargo electric tricycle. The batteries are generally equipped with 60V32Ah, 60V45Ah, 60V58Ah and other models, and this type of electric tricycle usually has better battery life and power than 48V electric tricycles. It is generally equipped with an 800-1200W motor. However, considering the comprehensive power and battery life, for a 60V electric tricycle, choosing an 800W motor is the most powerful and ensure longest battery life.
Next, let’s look at 72V electric tricycles, whose main models are large cargo tricycles. The batteries are generally available in 72V45Ah, 72V58Ah, and 72V100Ah models. This type of electric tricycle not only has a long range, but also has the most power. It is generally equipped with a 1000-2000W motor. Similarly, considering comprehensive power and battery life, a 1000W motor is generally the best choice for this type of electric vehicle.
To sum up, for 48V electric tricycles, 500W is the most powerful and have longest range, while for 60V and 72V electric tricycles, they need to be equipped with 800W and 1000W motors respectively, which will provide longer range and more power.
For electric tricycles, in addition to configuration, good usage habits also affect the battery life and power of electric tricycles. For example, do not let water enter the electric tricycle motor to prevent the motor from demagnetizing and rusting, which affects the power; do not overload the electric tricycle to prevent straining the battery and affecting battery life and service life; do not mix chargers to prevent bad charging of the battery, etc.
Maintenance Elements Of Using Tricycle Engine
Load selection
Engine load directly affects the strength and life of its components. When the load is increased, the work load of each assembly will also increase, and the amount of wear will increase; if it is a new vehicle, the wear will be greater. In order to limit the maximum speed of the initial driving period, reduce the load, and prolong the service life of the engine, a new car or a vehicle after an overhaul is generally equipped with a speed limiter on the carburetor. If the speed limiter is removed prematurely, it will cause abnormal noise, oil leakage, air leakage and power drop of the engine prematurely, and shorten the service cycle of the engine.
The choice of fuel and lubricating oil
The selection of fuel must comply with the required grades. The use of low grade fuel engines will produce knocking, which will subject the mechanical parts to strong impacts and increase the additional load of the parts, thereby accelerating the wear of the parts. The high temperature, high pressure and shock wave generated by knocking will also destroy the lubricating oil film on the cylinder wall and deteriorate the lubrication of the machine parts. In addition, fuel with excessive impurities will also accelerate the wear and corrosion of mechanical parts.
The choice of lubricating oil should also meet the working needs of the engine. If the viscosity of the engine lubricating oil is low, the lubricating oil pressure will be low, and the oil film will not be formed, causing boundary friction or dry friction; if the lubricating oil viscosity is too high, the fluidity will be poor. It is not conducive to cold car starting. At the same time, it takes a long time for the lubricating oil to reach the lubrication part through the oil filter, which increases the start-up wear.
The lubricating oil should be filled in an appropriate amount. When the oil level is too high, it will not only increase the movement resistance and reduce the power, but also cause the lubricating oil to flee into the cylinder and burn, causing excessive carbon deposits; and when the lubricating oil is too little, the oil pressure will be low. It is difficult to form an oil film, and it will cause dry friction or boundary friction, increase wear, abnormal noise in the bearing, and even serious accidents such as cylinder pulling and tile burning.
Cold start and cooling water temperature
When starting a cold car, especially in winter, you should try to use warm-up measures or cold-rolling, slow-turning, and low-speed warming. It is forbidden to bang the throttle. Because the lubricating oil has a higher viscosity when the engine is cold-started, it takes a longer time to reach the lubrication part. There is evidence that when the temperature is -15 ℃, the lubricating oil can flow to the connecting rod bearing and the movement pair on the cylinder head for 2 minutes after starting. During this period of time, if the throttle is sharply increased, the engine speed will be rapid. Rising, dry friction will be formed in the parts where the lubricating oil has not reached, which will intensify wear.
When the engine temperature is too high, the lubricating oil becomes thinner, and the lubricating oil film cannot be formed well, which will also increase the wear of the mechanical parts, and it is also very easy to produce knocking. But do not blindly remove the thermostat due to the high water temperature to make the engine work at low temperature for a long time, which will also cause excessive engine wear.
Road
The quality of the road surface has a great influence on the speed of the vehicle, fuel consumption and wear. If the road is sandy or muddy, the driving resistance is constantly changing; when the resistance is large, the engine works under heavy load conditions. At this time, the pressure in the cylinder increases, and the wear intensifies.
Climate
In winter, because the viscosity of lubricating oil is low, it enters the lubrication part slowly, which makes the engine dry friction for a long time; in the hot summer, the parts of the car are in a hot state, when the ambient temperature is 40 ℃, it will seriously affect the electrical components In addition, due to the high temperature, the lubricating oil becomes thinner and the oil film is difficult to form, which increases the tendency of the engine to dry friction.
Driving
The proficiency of driving skills also affects the performance and service life of the engine.
An axial arch-shaped groove is formed in the surface of a base circle of a cam and extends to an extension section of the base circle of the cam. An arc-shaped groove corresponding to the arc-shaped groove in the extension section of the base circle of the cam is formed in an inner hole wall of a timing driven gear, a round hole is formed by enclosure of the two arc-shaped grooves, and a decompression eccentric pin is arranged in the round hole. One end of the decompression eccentric pin penetrates out of the round hole and is placed in the arc-shaped groove in the surface of the base circle of the cam, the other end of the decompression eccentric pin penetrates out of the timing driven gear and then is connected with an eccentric block, and a reset spring is arranged between the eccentric block and the timing driven gear. One section of the decompression eccentric pin, placed in the arc-shaped groove in the surface of the base circle of the cam, is provided with an eccentric portion, when the eccentric block is in a reset state, the eccentric portion protrudes out of the surface of the base circle of the cam and ejects a lower rocker arm which controls an exhaust valve to open. The motor tricycle engine decompression starting mechanism can greatly reduce engine starting difficulty, and is beneficial for popularization and market acceptability of large-discharge motor tricycles.
Tricycle engine compatibility
Most front wheel motors will work on the trike and will install in a very similar way.ranging in price from a couple of hundred dollars up through sensible prices to quite silly.
Most crank motors will also work and be easy enough to install. This The advantage is that it uses the gearing system on the trike, so it works better than a hub motor when the trike is going very slowly. The disadvantage is that it's a pedal-assist motors, so it only works if you're pedalling.
My suggestion is that you find a local bike shop that has experience with electric bikes, ideally one that sells kits, and get them to supply and fit a kit for you. While it's possible to do the work yourself, unless you have the rights tools and experience it's very easy to make mistakes and end up with something that's unsafe, doesn't work, or is unreliable.
