Boost China rail transit development with reliable fastening

Since the 1990s, China's high-speed railway has experienced a great-leap-forward development process of introduction, innovation, speed acceleration and high-speed development. By the end of 2021, the total mileage of China's high-speed railway has exceeded 40000 kilometers, ranking first in the world. The highest operating speed is 350km / h and has become the standard setter in the world.

The safety of high-speed rail is the primary consideration of engineers in various countries. The safety of locomotives is inseparable from the reliable design and stringent quality of each component, which contains a large number of C-parts.

As the first country to develop high-speed rail, Germany has developed a series of DIN25201 standards for fasteners in the rail transit field, and expounds the conventional requirements of fasteners in the rail transit industry from key aspects such as classification / design (mechanical & electrical) / anti-loosening / anti-corrosion / installation. Würth, as the largest supplier of C-parts in Germany, is the faithful executor of these standards. Würth Industry has brought suitable C-Parts for rail transit and global quality standards to China, contributing to the vigorous development of China's railways.

Vehicle Body

Operating environment and technical requirements:

As the car body bears all kinds of vertical and horizontal loads caused by vehicle operation, the strength and stiffness of the car body must be effectively guaranteed. Therefore, the fasteners installed on the major load-bearing beams and bases must have high strength, good anti-loosening, strong anti-corrosion ability.

Typical products and characteristics:

High strength stainless steel bolts with high anticorrosion coating, nuts, thread inserts, securing parts and thread sheaths that need to increase the connection strength in the form of expanded basic dimensions.

Bogie

Operating environment and technical requirements:

Bogie is a kind of walking device which can rotate relative to the car body, it bears the self-weight and load of the vehicle body, and is driven on the rail by the locomotive. The connection of the upper part of the bogie must ensure sufficient strength and good running stability, and the connection of the driving part requires high precision and anti-loosening performance.

Typical products and characteristics:

Environmental friendly Galvanized Screws, 200HV Washers, Lock Nuts, Disc Springs, etc.

Braking Device

Operating environment and technical requirements:

The braking device, which is placed on the bogie as the drive unit, is the top priority of locomotive security. The fastening system in which the brake wheels are fixed on the hub, in addition to bearing alternating loads, the whole system will be alternately high and low temperature. Würth Industry, which has in-depth research on the application of fasteners, has been working with customers to improve and develop fastening systems against high temperature creep and fatigue for a long time.

Typical products and characteristics:

Hexagonal Bolt with Full Thread, Bar Bolt, All-Metal Locknuts, etc.

Coupling Device

Operating environment and technical requirements:

The coupling device is a device that connects the vehicle with each other to transmit the longitudinal traction force and ease the impact of the train in operation, commonly known as the coupler. The fasteners on the coupler must have extraordinary malleability, in a specific position, when the force reaches the safety limit, it must cause the protective fracture of the bolt to ensure the safety of the whole vehicle.

Typical products and characteristics:

Austenitic Stainless Steel Fastener, Carbon Steel bolt, Fine Thread Flange Screws, etc.

Interior Device

Operating environment and technical requirements:

The interior device refers to the equipment that meets the conditions required by passengers. Including seats, berths, tea tables, luggage racks, water supply equipment, sanitary equipment, air conditioning and ventilation equipment, lighting equipment. The C -parts used are mainly concerned with aesthetics, practicality, safety, and health.

Typical products and characteristics:

Stainless Steel Screws and Nuts, Handle, Springs, T-Head Screws, Quick Fastener for Narrow Area Installation, etc

Electrical equipment

Operating environment and technical requirements:

The main circuit system of the locomotive is composed of the traction motor and its related electrical equipment and connecting lines. Its function is to transform the electrical energy of the power grid into the traction force needed for the operation of the vehicle, and to convert the kinetic energy of the vehicle into the electric braking force. The main circuit is the high-voltage, high-current and high-power power circuit on the vehicle, and the control circuit is the circuit that controls the operation of the main circuit and auxiliary circuit, which can make the train control system run normally. Electrical equipment is very important to the safe operation of locomotives, so the reliability of any C-parts will affect the safe operation of locomotives.

Typical products and characteristics:

Flaig + Hommel Locking Nuts, Contact Washer, Wiring-Duct, Cable Tie, etc.

Focus on the development of rail transit industry

After years struggling, the rail transit of China have changed from a "pursuer" to a "leader".

As an important part of national infrastructure, rail transit is still developing at a high speed, such as the development of vehicle and the improvement of rail network. It is constantly overcoming one difficulty after another. Würth Industry China will try our best tp meet the needs of rail transit industry with best products, best quality and best service.
