Semi trailer is a common type of transportation vehicle in our daily life. There are many semi trailer parts on a semi trailer, all of which play different roles. Commonly used semi trailer parts are: axles,landing gear,king pin, rope tensioner, Spare tire rack, etc. Below, we will mainly introduce four types of semi trailer parts to you.
Semi trailer parts: axle
The axle is also called a half axle. The half axle is a shaft that transmits power between the main reducer (differential) and the driving wheels. Mainly solid. Simply put, it is a cylindrical part that bears the weight of the vehicle body.

Semi trailer parts: landing gear
The landing gear are an important part of a semi trailer. Truckers in some regions are also known as “horse legs”. Commonly used landing gear have a travel distance of 480 centimeters and a closing height of about 90 centimeters. Their function is to support the semi-trailer after it detaches from the front of the vehicle. There are two types of landing gear in the parts of the semi-trailer: single acting landing gear and linkage landing gear.

semi trailer parts: King pin
The king pin is an important connecting component. Connect the semi-trailer to the towing vehicle and withstand the traction force. When a vehicle starts, brakes, or travels on a slope, it is subjected to significant impact force.Therefore, the traction pin needs to have high strength and toughness. Meanwhile, due to the frequent collision and relative motion between the main and auxiliary pins, the connecting surface needs to be wear-resistant and must have high hardness. The semi trailer parts are very important and we must inspect them one by one. It is not allowed to have cracks or manufacturing defects. There are two types of semi-trailers connected by traction pins: welded and bolted. When replacing worn or damaged main pins, bolted connections are more convenient.

Semi trailer suspension is divided into mechanical suspension and air suspension. The mechanical suspension we usually refer to is also called a semi suspension. It uses a series connection method to balance the leaf spring. It can withstand vertical forces and absorb impacts, and is fixed to the bridge body with U-bolts. The force in the horizontal direction is transmitted by the bracket and connecting rod. There is a balancing device inside the suspension. Therefore, when the vehicle passes through uneven roads, the load on the rear axle can be balanced within a certain range. The material of the plate spring for trailer suspension is 60si2mn. The number of steel plates for hanging leaf springs is 8, 10, and 13. If the customer has a demand, they can also have different pieces according to their requirements.connections are more convenient.
