Axle
The semi-trailer axle is the core load-bearing component of the trailer. It is installed on the suspension, equipped with wheels and tires at both ends, and integrated braking assembly. It bears the weight of the whole vehicle and the trailer, and realizes vehicle braking at the same time. The mainstream of African trailers is
13 ton, 16 ton drum axle
You can also choose a disc axle.
structural composition
Axle housing
High-strength seamless steel pipe can withstand bending and heavy loads, making it difficult to deform.Wheel hubs and bearings
Support the tire to rotate and carry the load.brake assembly
Drum type: brake drum + brake pad + cam mechanism, cheap spare parts, simple maintenance, the most popular in Africa;
Disc type: brake disc + brake caliper, good heat dissipation, faster braking response, higher price;
Shaft head, oil seal
Protect the bearing to prevent oil leakage and sediment from entering.
Mainstream parameters (trailer)
Rated load: 13Ton /16Ton
Suitable tires: 12R22.5 vacuum tires
Suitable models: skeleton car, flat semi-hanging, side curtain semi-hanging
Purpose and function
core role
Load-bearing: supporting the trailer frame, container or cargo weight, transferring the load to the tires.
Transmission brake: with the air brake system, to achieve wheel deceleration, parking;
Positioning wheels: ensure the tire track and maintain the stability of the vehicle.
applicable scenario
Port yard short down: skeleton car transfer container, frequent start and stop, 13 tons drum bridge durable and easy to repair;
West Africa Cross-border Container Trunk Line (Ghana, Nigeria): Long-distance and heavy-duty, abundant parts market, convenient maintenance;
Engineering infrastructure transportation: flat trailers pull construction machinery, steel, and 16-ton heavy-duty axles are suitable for heavy-duty dirt roads;
Side curtain semi-hanging general merchandise pallet transportation: optional disc axle, more stable braking, protect the packaged goods.
