Treasure supplier behind DARO trailer axles

The trailer axle is no stranger to the owners. As an important part of the chassis, it plays an irreplaceable role in vehicle performance. To produce an axle, in addition to raw materials, it also needs bearings, hubs, brakes, friction plates, camshafts, bolts, washers, adjusting arms and other large and small parts of nearly 100.

These parts and the axle is the whole and part of the relationship, but also determines the quality and performance of the axle finished key factors. Today, we're going to talk about the treasure trove suppliers behind DARO's trailer axles.

1. Raw material -- Tianjin steel pipe

Raw materials are the premise and basis of trailer axle quality. If the performance of raw materials is not up to standard, a series of subsequent production and processing will be meaningless.

DARO trailer axles insist on using 20Mn2 seamless steel pipe produced by Tianjin Steel Pipe Manufacturing Co., LTD., which has better tensile strength, yield strength, impact toughness and other properties than ordinary steel pipes. Based on this, the axles processed have better strength, toughness, elongation, fatigue resistance and other properties.

Tianjin Steel Pipe Manufacturing Co., LTD., also known as "big seamless", is the key project of national energy security strategy construction during the Eighth Five-Year Plan period, is the leading domestic seamless steel pipe production enterprise, annual production of 3.5 million tons of seamless steel pipe, products covering oil and gas exploitation, chemical industry, electricity, Marine engineering, military, construction machinery and other fields. It has won the nomination award of the second China Quality Award and the titles of National Quality Management Outstanding Enterprise, National First batch of innovative enterprises, intellectual property advantage Enterprise, etc., which can provide complete supporting solutions for the seamless steel pipe needed in the global energy development and industrial field, and maintain long-term stable trade relations with customers in more than 100 countries and regions around the world.

2. Bearing -- Luoyang LYC Bearing Co., LTD

Bearing on the axle plays an important role in force transmission, decompression, cushioning and so on, not only to provide guidance for the steering of the hub, bearing axial load and radial load, but also need to maintain the flexibility of rotation and speed stability, cushioning from the road vibration.

A high-quality axle not only requires bearings with high precision, high bearing capacity, low roll resistance, high temperature resistance, fast heat dissipation, but also with uniform speed, small noise, high efficiency, long service life and other performance.

The bearings of DARO trailer axles are Luoyang axles, which are produced and supplied by Luoyang LYC Bearing Co., LTD. (hereinafter referred to as Luo Axles).

Founded in 1954, the company has accumulated more than 60 years of industry experience. The scale of production and marketing and supporting service capability rank in the forefront of comprehensive manufacturing enterprises in the bearing industry in China. Roshaft has passed ISO9001, ISO14001, TS16949, CRCC, OHSAS18001, appraisal, AAR, AS9100C, GL, Germany and other domestic and foreign authority certification, has repeatedly ranked the first in the industry quality ranking. Products exported to the United States, Germany, Italy, Australia, South Korea, India, Vietnam and other more than 70 countries and regions.

3. Wheel hub -- Henan Huateng Heavy Industry

The hub is the core part of the axle, also called the wheel ring, steel ring, tire bell, used to support the tire, buffer the impact of the outside, realize the tire and the road contact, ensure the vehicle driving.

DARO axle hub is produced by Huateng Heavy Industry, with good stiffness, toughness and precision, good heat dissipation, high roundness, not easy to deformation, high speed balance ability, at high speed can maintain good sealing, reduce or avoid sundry entry, prolong the maintenance cycle and service life, more suitable for users with long mileage.

Henan Huateng Heavy Industry Technology Co., Ltd. is located in the industrial agglomeration zone of Suiping County, Henan Province, covering an area of more than 70 mu. The main products cover wheel hub, brake drum, ball nut, positioning set, shaft nut and other series. The company has successfully passed the ISO/TS16949 international quality management system certification for three consecutive years. Also with a number of domestic axle plant, trailer plant to maintain long-term stable cooperative relations.

4, brake pads - Anhui Feiying

Brake pads are the most critical safety parts in the vehicle brake system, through the rotation of the brake drum or brake disc friction to achieve the effect of vehicle deceleration or stop, directly related to the safety of people and vehicles.

A qualified brake pad, need to have stable friction performance and higher friction coefficient, in the case of continuous braking decline rate as small as possible, at the same time to be able to withstand higher load, with lower wear, to provide stable and reliable braking effect to the vehicle.

The DARO axle uses Anhui Flying Eagle brake pads.

Anhui Feiying Auto Parts Co., Ltd. was founded in 2005, is one of the large professional brake pad, clutch production and manufacturing enterprises, covers an area of about 120 mu, currently has 10 workshops a total of 80,000 square meters of international standard plant, It has passed ISO/TS16949 international quality system certification, IATF16949 quality management system certification and national compulsory 3C certification. The annual production of friction materials exceeds 10,000 T, and its production capacity and output are among the best in domestic peers.

5. Brake pliers -- Longzhong Holdings

Brake clamp is the main friction couple on the axle, but also one of the key parts of the vehicle brake, need to have good strength and stiffness, as high as possible and stable friction coefficient and appropriate wear resistance, heat resistance, heat dissipation and heat capacity.

DARO trailer axle brake clamp by Longzhong Holding Group manufacturing, raw material selection of high-strength alloy, fast heat conduction, more wear-resistant, thermal attenuation and water attenuation ability is strong, not easy to deformation, improve driving safety.

Longzhong Holding Group Co., Ltd. is located in Chengbei Industrial Zone, Yuhuan City, Zhejiang Province. Founded in 1988, Longzhong Holding Group was approved by the State Administration for Industry and Commerce in 2006. It has been committed to the development and manufacturing of commercial vehicle braking system and engine parts, and its products are widely used in well-known engine factories and auto factories at home and abroad. At home and abroad to enjoy a higher visibility, through the ISO/TS16949 certification, ISO14001:2004 standards, and in 2012 through the China National Accreditation Committee for Conformity assessment audit, the CNAS accreditation committee recognized.
