Definition and function of electric tricycle brake
Definition of electric tricycle brake: The brake is a mechanical braking device that can slow down the speed of the vehicle, also known as the decelerator.
If you step on the brake pedal, the brake lever will be pressurized and the brake pads transmitted to the brake drum will jam the brake disc, causing the car to slow down or stop. run.
The role of electric tricycle brakes: When the electric tricycle brakes, the metal diaphragm is closely combined with the metal ring of the tire shaft when you brake.
When the vehicle is decelerated until it stops through friction, the main function is to decelerate and stop.
Type of brake
There are four common types of brakes:
Disc brakes.
It mainly adopts hydraulic transmission, the brake resistance arm is large, and the effect is good.
It is generally used for high-end cars, and it will become more and more common in the future.
Drum brake. It mainly adopts mechanical transmission, and the brake resistance arm is smaller than that of disc brakes, but the price is low, and the braking effect is still good.
Hold the brake.
It mainly adopts mechanical transmission, and the brake resistance arm is smaller than that of the disc brake.
This is the traditional method used by early electric vehicles.
The biggest disadvantage is that there will be a sharp whistle when braking, which is gradually eliminated.
Raise the brake.
This kind of brake not only has good effect, but also has high safety.
However, due to the limitation of wheel hubs, it is not easy to modify, which is not conducive to many people who like to assemble and reconfigure.
Due to the different structures of the rear wheel of the electric bicycle, only the expansion brake or the holding brake can be installed, so the drum brake pad is wider, the friction torque is large, and the wear is small and the service life is long.
However, due to the large operating torque, the general expansion brake is manual, and the cable is too long, the service life is short, and the effect is not as good as the drum brake.
Comparison of the advantages and disadvantages of electric tricycle brakes
At present, electric tricycles mostly use drum brakes or disc brakes, so what are their advantages and disadvantages?
Advantages and disadvantages of drum brakes Drum brake is a brake device that uses the stationary brake pads in the brake drum to rub the brake drum that rotates with the wheel to generate friction to reduce the rotation speed of the wheel. Advantages:
Due to the low level of manufacturing technology of drum brakes, it is the first to be used in brake systems, so the manufacturing cost is lower than that of disc brakes. Disadvantages:
The brake heat dissipation is not good during high-speed driving, and it is easy to accumulate heat to cause heat exhaustion in the brake part, and the braking force is weakened.
Advantages and disadvantages of disc brakes The full name of the disc brake is the disc brake, which is composed of a brake disc connected to the wheel and a brake caliper on the edge of the disc.
Advantages: Disc brakes have the characteristics of fast heat dissipation, light weight, rapid braking, and easy adjustment.
The high temperature resistance performance is also better under high load, the braking effect is stable, and it is less affected by external environmental factors.
In addition, the disc brake is caliper type, the brake pad and the disc are in flat contact, the contact surface is large, the braking is fast, it is suitable for frequent braking, and generally does not need to be adjusted. Disadvantages:
First of all, the manufacturing cost of disc brakes is significantly higher than that of drum brakes. In addition, the braking force is not as good as that of drum brakes.
Choose electric tricycle brakes
We choose the brakes of electric tricycles from the following points:
a. The drum brake has a good self-braking effect. It can use the brakes to open the pads, and the wheel rotates with the outstretched brake drum twisted by an angle.
b. The manufacturing technology of drum brakes is relatively low, and it is also the first to be used in brake systems, so the manufacturing cost is lower than that of disc brakes.
c. In addition to the lower cost, the difference between the drum brakes of large cars and small cars may only be that large cars use air assist, while small cars use vacuum assist to help brake. This type of brake is more practical.
d. In addition to the low cost, under the condition of the same diameter, the absolute braking force of the drum brake is greater than that of the disc brake, and the drum brake can increase the braking force by turning the wheels forward.
Conclusion
The choice of brakes for electric tricycles is an important matter, which determines the flexibility and safety of electric vehicles. More details welcome to subscribe
