Material and other items.The suspension of existing trailer underbody be typically formed with beam welding, although can meet it is general use function,
But since its weld is there are welding stress, it is easy to be destroyed when overload or when by larger external force, at this, while it subtracts
Shock stability is very poor, jolts acutely when by uneven road surface, and compartment is unstable, is easy to overturn, poor by performance.
Utility model content
In view of the above-mentioned problems, the utility model is intended to provide a kind of trailer underbody suspension fork mechanism, can be moved through in trailer
Play the role of damping in journey, while being not easy to be destroyed in slight overload, can also be passed through in bumpy road.
The technical solution of the utility model is a kind of trailer underbody suspension fork mechanism, including vehicle frame main beam, vehicle frame axis, wheel branch
Frame, axletree and wheel, the vehicle frame main beam arrange that the vehicle frame axis vertical symmetry is arranged in vehicle frame master along trailer's length direction
Beam both sides, vehicle frame axis one end are connected perpendicularly to by bolt on vehicle frame main beam, and the vehicle frame axis other end is connected to wheel stand
Middle part, wheel stand is axial perpendicular to vehicle frame axis, is continuously decreased to height at both ends in the middle part of wheel stand, wheel stand two ends
Place extends outward axletree, and the axletree is arranged in parallel with vehicle frame axis, and the wheel hub of the axletree end point and wheel connects
Connect fixation.
Preferably, it is vertically installed with pilot hole in the middle part of the wheel stand, has the shaft shoulder, vehicle frame shaft end to insert in the middle part of vehicle frame axis
It is pierced by after entering pilot hole, vehicle frame shaft end is located at wheel stand outside and is vertically installed with locating ring and lock pin to by wheel branch
Frame is fixed on vehicle frame axis and is resisted against on the shaft shoulder.
Preferably, further include screw, the screw penetrates the company of positioning in the vehicle frame axis in pilot hole on the outside of wheel stand
It connects.
Preferably, it is extended with connecting plate close to vertical vehicle frame axis direction at vehicle frame main beam on the vehicle frame axis, bolt passes through
Connecting plate is connected on vehicle frame main beam, and reinforcing rib is provided between the connecting plate and vehicle frame axis.
Preferably, the axletree end set has threaded connection block, leads between the threaded connection block and hub for vehicle wheel
Bolt and nut is crossed to be connected and fixed.
The utility model can play the role of damping, and improve the height on chassis, while also not in slight overload
Be vulnerable to destruction, can also be passed through in bumpy road, structural strength and good rigidity, and each component junction do not use it is conventional
It is welded to connect, avoids the generation of welding stress so that overall structure is more reliable and more stable.
