What are the trailer accessories? Trailer parts factory which is reliable?

With the increasing prosperity of China's maritime transport, road freight and container transport market, the semi-trailer market is also developing, and the market demand for various types of accessories related to it is also growing.

Semi-trailer accessories, as the name suggests, refers to the various parts used on the semi-trailer, the more common trailer axle, suspension, leaf spring, leg, air chamber, air storage cylinder, steel ring, tires, relay valve, tightener, spare tire elevator, pull rod, traction pin, suspension, which traction pin, axle, tire, steel ring, leg, suspension as the main purchased parts.

1. Traction pin

The main function of the traction pin is to connect the semi-trailer with the tractor, and connect with the main vehicle traction seat to pull the semi-trailer.

At present, the traction pin on the market is mainly divided into four types, assembly 50, assembly 90, welding 50, welding 90, users can buy according to different models and actual use.

2. Trailer axle

Trailer axle, also known as axle assembly, the main function is to load, maintain the normal driving of the semi-trailer on the road, connected with the frame through the suspension, and the wheels are installed at both ends of the car, which plays an important role in the power, stability and carrying capacity of the car.

In general, when it comes to the semi-trailer power core, owners can easily think of the engine and gearbox. But in fact, the trailer axle is also one of the semi-trailer power core assembly, which plays a link role in the power transmission process. If the trailer axle is not selected well, it directly affects the safe use of the vehicle.

3. Tires

The tire is in contact with the road surface, bearing the weight of the car, and together with the suspension of the semi-trailer, it plays a role in easing the impact, maintaining good adhesion with the road surface, and improving the tractive, restraining and passability of the semi-trailer. If a semi-trailer does not have wear-resistant, heat-resistant, durable tire support, its safety performance and economic benefits are out of the question.

Tires are rubber products, in addition to wear and tear will also age naturally, the owner usually needs to pay attention to the maintenance and inspection of the tire, timely cleaning of debris, once found cracks, etc., to be replaced in time.

4. Steel rings

Also known as the hub, refers to the tire outline to support the tire, cylindrical, center mounted on the axle components, is an important part of the semi-trailer. The driving process of the semi-trailer will produce transverse and longitudinal loads, accompanied by the driving torque and braking torque, so the hub needs to bear a considerable part of the load, the vertical and horizontal oscillation should be small, the loss of measurement and the moment of inertia should be small, the stiffness, strength and accuracy should be high.

In order to meet market demand, many manufacturers have introduced steel rings have been improved, such as seal structure design, maintenance process simplification, maintenance cycle extension, etc., owners can choose according to demand when buying.

5. Leg support

The leg is a semi-trailer support device, which uses the principle of "standing wood top thousand weight" and is located at the front end of the semi-trailer frame for use after the semi-trailer is separated from the tractor, and its role is very critical as an important tool in the area of dispersed force concentration.

6. Suspension

Suspension is the general name of the force transfer connection device between the frame of the semi-trailer and the axle of the trailer, the role is to transmit the force and force torsion between the wheel and the frame, buffer the impact force transmitted by the uneven road surface to the frame or body, reduce the resulting vibration, so as to ensure that the car can run smoothly.

Semi-trailer suspension can be divided into steel plate suspension, air suspension, rigid suspension and single point suspension, among which steel plate suspension is the highest application rate of ordinary semi-trailer in China. With the introduction and implementation of relevant regulations, the utilization rate of air suspension is constantly increasing, especially in the field of high-end transportation, the advantages of air suspension are more obvious, and it is also more and more favored by owners.

These are the main purchased parts of the semi-trailer. So, which of the semi-trailer parts manufacturers is reliable?

Looking at the current domestic semi-trailer parts market, one side is the high-profit industry giants, the other side is the process of substandard workhouse-style products, the polarization trend is more obvious. However, there are also many brands with reliable quality and reasonable prices, and owners need to shop around when buying. For example, the trailer axles, axles and semi-trailer accessories produced by DARO Group have been standing in the market for more than 20 years, the quality can withstand the test, the price is not adulterated, the price is excellent, and it is welcomed by users.
