How to measure the wheel base of the trailer axle?
Many owners in the purchase of trailer axles, often asked about a parameter is the wheel base, just like choosing clothes to see the size, the wheel base also determines whether the trailer axle can match the vehicle.
Generally speaking, under the same load-bearing tonnage, there are often trailer axles with different wheel bases, and how to measure the main vehicle to get an accurate wheel base value?
Wheel base refers to the distance between the center line of the track left by the wheel on the vehicle support plane, which can be visually judged by the following figure:
Therefore, if the two sides of the vehicle are twin structures, the wheel base is the distance between the center planes of the two wheels on one side.
It should be noted that the wheelbase is not a parameter, the wheelbase refers to the distance between the center of the front axle and the center of the rear axle of the vehicle, simply speaking, the distance between the front and rear axles of the vehicle, related to the length of the vehicle turntable, the owner should not confuse it with the wheel base.
Next, we talk about several common trailer rear axle on the market and its main characteristics, the owner can choose according to their own use conditions.
1, American trailer axle
The American trailer axle is the most used in the country, the most widely used, the most obvious advantages are strong bearing capacity, durable and resistant, relatively low price, cost-effective, in addition to simple design, maintenance is more convenient, all kinds of accessories are also common in the industry, good to buy good to match, can be used in all kinds of general cargo transportation, Such as sand and stone, steel coil, wood, coal and other heavy cargo transportation can also be applied.
2, German trailer axle
The characteristics of the German trailer axle is long-term, stable and lightweight, on the one hand, save fuel and tires, can reduce the comprehensive cost of the vehicle, on the other hand, the maintenance cycle is long, the heat dissipation efficiency is better, suitable for use in the transport of the transport time, vehicle presence has certain requirements of the transport conditions, especially suitable for long-distance standard transport, such as suspension, port, cold chain, green pass, express transport.
3, low flat trailer axle
Low flat trailer axle belongs to a special trailer axle, used in low flat semi-trailer, according to the provisions of low flat semi-trailer mainly transport can not disassemble large goods, so the trailer axle needs to meet the requirements of strong bearing, stable transportation, convenient loading and unloading of goods. The most obvious feature of the low flat trailer axle is that the wheel end is small, the height is low, the center of gravity is low, and the wall thickness parameter is relatively higher, which is suitable for transporting all kinds of large goods, such as mechanical equipment, large tanks, construction equipment, power station equipment, etc.
4. Eccentric trailer axle
Eccentric trailer axle and low flat trailer axle in the pursuit of low center of gravity has the same good, the difference is that the eccentric trailer axle beam is special treatment, can further reduce the chassis height of the frame, mainly used in some car, so that it is not too high under the premise of obtaining more loading space, At the same time, it can reduce the turning radius, improve the grip of the tire, and the transportation stability is conducive to speed up, and the loading and unloading of goods is also more convenient.
5, disc trailer axle
The advantages of disc trailer axle are mainly manifested in brake sensitivity, thermal attenuation and water attenuation resistance, braking force output stability, lightweight and so on. Especially with ABS, EBS, hydraulic retarders, air suspension and other devices, the advantages of disc trailer axle can often be played to a greater extent. In addition to the mandatory requirements of the three-axis fence grid semi-hanging, those who require high freight damage transport conditions, such as dangerous chemicals, precision instruments, fragile items, valuables, flowers, fruits and vegetables transport can choose the tray trailer axle.
Light trailer axle is mainly for the rear axle of the trailer, such as bearing 3t, 5t, 6t, 8t, etc., which is characterized by small tonnage, more flexible installation and use, mainly used in all kinds of industrial trailers, agricultural trailers, field trailers, station trailers, trailer trailers, animal husbandry trailers, specifications including parts can be customized production.
7. Three lines and six axes
Three-line six-axis trailer axle is mainly used for large or oversized transport, this kind of cargo volume, weight is large, generally not removable, the need for large or special vehicles for transport. The three-line six-axle trailer axle is specially customized for large transport vehicles, carrying up to 80t, and the number of tires is large, reducing the average pressure of the contact surface and reducing the damage to the tire and road surface.
