Problems solved by technology

However, since the suspension support plate (or shaft seat) and the side plate are seamlessly fixed, the deformation of the suspension support plate is small when the U-shaped bolt is used to clamp and connect, and the positioning protrusion and the positioning groove cannot be tightly matched. It is prone to looseness, so the axle will still have a small range of circumferential rotation, which will affect the stability of driving

Embodiment Construction

[0020] like Figures 1 to 4 As shown, the suspension and trailer axle positioning coupling structure of the present invention includes a suspension system 1, an axle 2 and a connecting piece for locking the axle 2 and the suspension system 1, specifically, the connecting piece is a U-shaped bolt 3. The suspension system 1 includes a base plate 13, a side support plate 12 and an axle seat 11, and the specific structure is as follows:

[0021] The shaft seat 11 is welded and fixed on the side support plate 12 by setting several support platforms 111 , and there are compression deformation chambers 112 between adjacent support platforms 111 . The axle base 11 is provided with a positioning projection 113 on one side of the vertical central axis A of the axle 2 , and the position of the axle 2 corresponding to the positioning projection 113 is provided with a positioning groove that cooperates with the positioning projection 113 . 21. The included angle α between the radial cente...

Abstract

The invention discloses a positioning coupling structure of a suspension and a trailer axle. The positioning coupling structure comprises a suspension system, an axle and a coupling piece, wherein the coupling piece is used for locking the axle and the suspension system; the suspension system comprises a base plate, a side support plate and an axle seat, wherein the axle seat is welded and fixed on the side support plate by a plurality of support tables, and compression deformation cavities are formed between the adjacent support tables; a positioning bulgy block is arranged on one side of the axle seat, which is positioned on a vertical axis of the axle, and a positioning groove which is matched with the positioning bulgy block for positioning is arranged in a position of the axle, which corresponds to the positioning bulgy block. According to the positioning coupling structure, the structure of the axle seat is improved, the compression deformation cavities are additionally formed, and reasonable positions of the positioning bulgy block and the positioning groove are adjusted, so that the positioning coupling structure can be used for tightly compressing and positioning without welding and fixing, the strength of an axle body is not weakened, and the coupling is firm and reliable.

Description

technical field [0001] The invention relates to a positioning coupling structure, in particular to a positioning coupling structure of a semi-trailer axle and suspension. Background technique [0002] Today's cars are equipped with suspension systems. Suspension is a general term for all force-transmitting connection devices between the car's frame and axles, axles or wheels. The main function of the suspension is to transmit all forces and forces acting between the wheels and the body. Moment, such as supporting force, braking force and driving force, etc., and ease the impact load transmitted to the body from the uneven road surface, attenuate the vibration caused by it, ensure the comfort of the occupants, and reduce the dynamic load of the cargo and the vehicle itself. The axle of the semi-trailer and the frame of the semi-trailer are firmly connected by the suspension system. At present, leaf spring suspension and air suspension are commonly used, and air suspension can...
