On the 21st, I learned from the Tianjin Postal Administration that in order to protect the environment and solve the "last mile" problem of express delivery, Tianjin has increased the promotion of new energy vehicles in the postal and express delivery fields. By the end of 2015, a total of 629 new energy vehicles were promoted.
Friction discs are components composed of chips and friction linings or layers of friction material, which are widely used in the fields of mechanical engineering, mechanical parts and clutches.
Brake pads, also called brake pads, are actually brake pads. In the braking system of a car, brake pads are very important safety parts and play a key role.Brake pads determine the quality of the braking effect and are closely related to the safety of the car, so the daily maintenance of the brake pads is particularly important.
The friction plate has a suitable friction coefficient: The friction coefficient is the basic parameter of the friction material, which determines the basic braking torque of the brake pad. The national standard strictly requires the manufacturer to indicate the friction coefficient on the package. The friction coefficient must be appropriate, too high will cause During the braking process, the wheels are locked, the direction is out of control and the disc is burned. If it is too low, the braking distance will be too long.2 Friction pads have reliable safety: Brake pads will generate instantaneous high temperature during braking, especially when driving at high speed or emergency braking. Under high temperature conditions, the friction coefficient of friction pads will decrease, which is called thermal recession. The level of thermal decay determines the safety of the high temperature state and emergency braking.

Tianjin is a pilot city for promoting new energy vehicles in the postal sector. Through purchase, lease, loan, etc., there are currently more than 10 models available for postal express delivery companies.
It is understood that in order to vigorously promote new energy vehicles, the Tianjin Post Administration has held a number of promotion and application work conferences and product promotion conferences to guide enterprises to establish a green development concept, and signed a strategic cooperation agreement with Beiqi New Energy Company to provide targeted services. The postal and express delivery markets will send letters to the national headquarters of express delivery companies to encourage greater support for the promotion of new energy vehicles and to guarantee policies and funds.
