Trailer axle ( Hydraulic trailer axle, dynamic platform car axle, tyred handling locomotive bridge) With the suspension structure and function principle

Application status and development trend of car trailer with the rapid development of automobile technology and road network, road freight volume increased year by year, logistics and transport industry of automobile transportation economy, high efficiency put forward higher request, trailer transport is an effective solution. Have can increase the tractor trailer transport effective working time, improve transport efficiency, and promote the advantages of multimodal transport logistics development and regional cooperation, and is helpful for social resources saving, energy conservation and emissions reduction, is a kind of transportation equipment for science and advanced management mode of the organization. Trailer axle ( Hydraulic trailer axle, dynamic platform car axle, tyred handling locomotive bridge) With structure and function of the suspension principle axle and suspension is an important part of the car trailer. Axle by means of suspension and chassis is linked together, it is installed on both ends of the wheel, its function is passed between the frame and the wheel force and moment of each direction according to different suspension structure, the axle is divided into integral and breaking two; According to former beam shape is different, can divide again I section and the circular tube section axle, axle of I section is currently the most widely used, its strength is big, easy to meet the requirements of the layout on the shape. Suspension chassis frame is the floorboard of the force transmission connection between the axle and everything, it's function is applied to the wheels in the road in longitudinal and vertical reaction reaction and side reaction and the reaction force caused by the torque will be passed on to the frame, in order to make sure the car moving. Automobile suspension is generally composed of elastic element, shock absorber and steering mechanism of three parts, it is divided into two major categories of non independent suspension and independent suspension [ 2] 。 The independent suspension can be divided into the leaf spring elastic element, the spiral spring, air spring, oil and gas spring, using spiral spring, air spring, oil and gas spring need to have more complex steering mechanism. And because using steel plate spring, leaf spring itself can concurrently act as guides, and vibration and has the certain, and thereby hanging structure is greatly simplified, so the car trailer usually USES the steel plate spring independent suspension and integral axle of I section.
