1、Important Components of Semi-trailer Landing Gear：

The main parts of trailer landing gears are a two-speed gearbox, a support sleeve, a support rod, a transmission screw (a crank handle) and a support plate. The structure is very simple and the function is very important.

2、Trailer Landing Gear Classification：

Trailer landing gears are divided into single action and linkage ; Single-acting landing gears refer to those that operate independently on both sides, with two cranks, and each outrigger has a gear box ; Linkage landing gears refer to one side of the operation and two sides. There is only one rocker , which is composed of one with a gear box and one without.

3、Trailer Lift Landing Gear

The lifting landing gear is composed of a supporting plate, a supporting leg, a transmission mechanism, a transmission mechanism, a transmission rod and a handle, etc., and is arranged at the front end of the semi-trailer. When the tractor is disengaged from the semi-trailer, it is used to support the semi-trailer to park. In order to adapt to the change of the height of the semi-trailer, the trailer landing gear is equipped with a screw lifting mechanism, so that the connection and disengagement of the semi-trailer and the tractor can be carried out smoothly. The height is divided into two speeds, fast and slow. When the handle enters, it rotates for high-speed lifting, and when the handle is pulled out, it is for low-speed lifting. When the support plate touches the ground, the landing gear will bear the load. At this time, only the low-speed gear can be used to lift and lower, otherwise the landing gear lifting mechanism will be damaged.

4、Important Components of Semi-trailer rims：

5、The advantages of aluminum alloy steel rim:

1.Energy saving and consumption reduction, good heat dissipation. The use of aluminum alloy steel rings can reduce the weight of the whole vehicle and reduce the rotational inertia of the wheels, which improves the acceleration performance of the vehicle and reduces the demand for braking energy, thereby reducing fuel consumption.

2.High security. For high-speed vehicles, it is not uncommon to see high-temperature tire bursts and reduced braking efficiency due to tire friction and braking. The thermal conductivity of aluminum alloys is three times that of steel and iron, and it is easy to dissipate the heat generated by tires and chassis into the air. Even in the case of long-distance high-speed driving or continuous braking on downhill roads, the vehicle can maintain the proper temperature and reduce the tire blowout rate.

3.High carrying capacity. The load-carrying energy of the aluminum alloy steel ring is 5 times that of the ordinary iron ring. The forged wheel was only deformed by 5 cm after bearing 71,200 kg. The iron ring has only been deformed by 5 cm after bearing 13,600 kg. In other words, the strength of the aluminum alloy rim is 5 times that of the iron steel ring.

4.Beautiful appearance. Aluminum alloy has better fluidity and tension than steel rims in high temperature liquid state, and the later polishing and electroplating process enables it to produce a more beautiful and changeable appearance; surface anti-corrosion treatment and electrostatic powder coating also make it durable like New.
