Description
Technical field
The invention belongs to hang axle technical field, and in particular to a kind of brakeless fixed hydraulic suspension axle.
Background technique
Suspension is the general name of the vehicle frame and vehicle bridge of automobile, all force transmission connections between axle or wheel, suspension
Main function is a shear force and the torque, such as support force, brake force and driving force etc. that transmitting acts between wheel and vehicle body,
And it mitigates and is vibrated caused by being transmitted to the shock loading of vehicle body by uneven road surface, decayed thus, the comfort of guarantee occupant, reduced
The dynamic loading of cargo and vehicle itself.And the two is securely joined by suspension between the axle and semi-trailer frame of semitrailer
Knot gets up, currently used to have leaf spring suspension and air suspension, and air suspension can more improve running car than leaf spring suspension
Ride comfort and comfort improve transport cargo security, and reduce the damage to highway pavement, play the work maintained public highway
With, thus gradually more applied.On current semitrailer international market, hangs and be substantially all with the connecting structure of axle
It is to be clamped with U-bolt, then axle is fixed in suspension with welding manner, to reach anti-rotation and prevent axle from axially altering
Dynamic purpose.Especially on air suspension, the connection with semitrailer axle is essentially all some producers using welding manner
The two is tied on the basis of welding along with U-bolt, the shortcomings that this mode is in the anti-of axis body welding position
Torsional strength can be reduced with flexural strength, reduce the service life of axle, especially when semitrailer is on the road surface of out-of-flatness
On when driving, by moment of flexure and when torque synergy, axis body is easy to appear cracking near welding position and even fails axle
Defect, in deadhead operation, all tire all lands most of trailers, in the process of moving, the frictional force of tire and ground
It increases, increases the power loss of tractor, oil consumption increases, and accelerates the tire wear of trailer, asks to solve this
Topic, is realized by the promotion to Trailer car shaft at present, and existing hoisting mechanism is the control using the additional complexity of air suspension
For valve processed come what is realized, structure is complicated for air suspension, and expensive.
Existing technology there are the problem of:
When existing Vehicular turn, because car body steering force is big, torsion is big, and oil cylinder is precision part, and the pars contractilis of oil cylinder is easily damaged,
