Description
Technical field
The utility model belongs to automotive supplies technical field, relates more specifically to a kind of single-point suspension.
Background technology
Suspension is the important component of connecting base plate and vehicle frame, and the support force of vehicle, brake force, driving force etc. all pass through
Suspension system is transmitted, and can also mitigate impulsive force of the bad road to vehicle, it is ensured that vehicle it is steady, its importance is not
Say and explain.Suspension typically has point of independence and rigid axle suspension, for semitrailer, due to needing stronger bearing capacity,
So what is used is all rigid axle suspension, and common semitrailer suspension has four kinds：Rigid suspension, single-point suspension, single-point suspension
And single-point suspension.
Single-point suspension advantage is light weight, reduces the impact that vehicle body is subject to, and improve the traction of wheel；Can
With the small relatively slinky spring of rigidity, improve the comfortableness of automobile；Engine location can be reduced, centre of gravity of vehicle is also reduced,
So as to improve the riding stability of automobile；Left and right wheelses are individually beated, mutually incoherent, can reduce the inclination and vibrations of vehicle body.But
It is that single-point suspension is that leaf spring is fixed on axletree by U bolt and leaf spring fixed seat, in actual applications, single-point suspension
In leaf spring there is the phenomenon of left and right play, the leaf spring for occurring play is easy to the heel and toe wear for causing tire local, makes car
Traveling bring certain potential safety hazard.
The china national practical new-type patent of Patent No. 201320139053.2 discloses a kind of single-point with pin fixation and hanged
Hang, problem above is solved well, the patent when by plus load, is easily produced for stress concentration trailer axletree part
The problem of fatigue fracture easily occurs for raw ductile rupture, particularly leaf spring ends is not solved well, and leaf spring ends are once sent out
Raw fracture, axletree can produce different step displacements, and then occur serious traffic accident.How when fatigue fracture occurs for leaf spring ends,
Single-point suspension is protected, prevents axletree from producing different step displacements, it is to avoid the generation of traffic accident is extremely urgent.
The content of the invention
To solve the above problems, overcoming the deficiencies in the prior art, the utility model provides a kind of simple in construction, security
By force, when can avoid the suspension parts from being broken, axletree produces different step displacements, and then occurs the single-point of serious traffic accident and hang
Hang, the problem of potential safety hazard produced by suspension parts generation fracture can be effectively eliminated.
The utility model solve above-mentioned technical problem concrete technical scheme be：Described single-point suspension, including leaf spring, U
Shape bolt, leaf spring fixed seat and safe connection equipment, it is characterised in that the leaf spring fixed seat is arranged on the two ends of leaf spring, described
U bolt is arranged on the inside of the middle part of leaf spring, leaf spring fixed seat and is provided with safe connection equipment, and the safe connection equipment includes
Limited impression, connecting rod and spacing preiection, the connecting rod are provided at both ends with screw thread silk, and the spacing preiection is arranged to spheroid, spheroid
The internal thread being engaged with connecting rod is internally provided with, described limited impression is arranged to the hollow rectangular parallelepiped structure of a side opening,
The opening cross section is arranged to circle, and the diameter of opening is between the diameter of spacing preiection and the diameter of connecting rod
Between, described limited impression is welded and fixed with leaf spring fixed seat to be connected.
Further, described safe connection equipment material uses steel.
Further, described limited impression upper end is provided with installing port, the diameter of installing port and spacing preiection
Diameter is consistent.
Further, the length of the connecting rod is less than the length of leaf spring.
The beneficial effects of the utility model are：Described leaf spring U bolt, effectively prevent leaf spring or so play；It is described
Safe connection equipment greatly improve the safety coefficient of device；Described opening cross section is arranged to circle, and the diameter of opening is big
It is small between the diameter of spacing preiection and the diameter of connecting rod, both ensure that connecting rod during leaf spring is flexible
Normal displacement, screens is acted on when also ensure that fracture；The ball interior is provided with the internal thread being engaged with connecting rod, serves
The effect for being easy to safeguard beneficial to dismounting.
