Abstract
The invention discloses the semitrailer, and in particular relates to semitrailer without suspension system, which includes suspension frame, leaf spring, the front of leaf spring hinges with the suspension frame, and the back of leaf spring is slidably connected with suspension frame. The invention has the advantages of being simple structure, easy to operate, low in cost and maintenance-free. What's more, the kerb weight of vehicles is reduced by reducing the number of parts.
Description
Technical field
The present invention relates to semitrailer, specifically a kind of semitrailer no pull bar suspension.
Background technology
Semitrailer requires lightweight it is necessary to mitigate light weight now, needs to carry out structure to each position of trailer
Optimize, mitigate deadweight, semitrailer is coupled together vehicle bridge, tire and body frame structure for automotive by suspension, form bearing structure, existing
Common semitrailer suspension system be all made up of suspension holdfast, leaf spring and rod assembly, this structure is extensive at present
Use, but in the suspension of this structure, rod assembly and the parts being associated with rod assembly occupy very big weight
Amount, taking 3 axle semitrailers as a example, rod assembly and be associated with rod assembly component weight have 150kg, and
This structural elements quantity is many, high cost, usually occur in use simultaneously pull bar get loose lead to vehicle bridge sideslip and
Tyre irregular wear phenomenon, needs periodically to adjust wheelbase.
Content of the invention
Present invention seek to address that the problems referred to above, thus provide a kind of mitigation light weight, reduces cost, non-maintaining semi-mounted
Car no pull bar suspension.
The present invention solves described problem, the technical scheme is that
A kind of semitrailer no pull bar suspension, including suspension holdfast, leaf spring, leaf spring front end is cut with scissors with suspension holdfast
Connect, leaf spring rear end and suspension holdfast are slidably connected.
Using the present invention of technique scheme, compared with prior art, its prominent feature is:
Eliminate rod assembly and parts associated there, structure is simple, be easy to operate, parts reduce and significantly mitigate car
Deadweight and non-maintaining, reduce production cost.
Preferably, the present invention further technical scheme is:
Leaf spring front end is provided with grasswort, lining set in grasswort, and the riser of suspension holdfast or equalizer bar are provided with pin shaft hole, steel plate
Spring at front end passes through described pin shaft hole and bearing pin is hinged with suspension holdfast, and leaf spring front end grasswort instead of in prior art
The effect of the pull bar of suspension, therefore eliminates rod assembly and parts associated there, and structure is simpler, significantly
Mitigate light weight.
Suspension holdfast includes front suspension support, the first middle part suspension holdfast, the second middle part suspension holdfast, rear suspension are propped up
Frame, the riser of front suspension support, first middle part suspension holdfast equalizer bar rear end, second middle part suspension holdfast equalizer bar after
End is hinged with the front end of leaf spring respectively, the equalizer bar front end of the first middle part suspension holdfast, the second middle part suspension holdfast flat
Heng Liang front end, the riser of rear suspension support are slidably connected with leaf spring rear end respectively.

Specific embodiment:
With reference to embodiment, the invention will be further described, and purpose is only that and more fully understands present invention, therefore, institute
The example of act is not intended to limit protection scope of the present invention.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, leaf spring 2 rear and front end be arranged at by suspension holdfast riser 9 or balance
In the notch that beam 6 is formed, limit the left and right translation of leaf spring 2 and rotate, suspension holdfast includes front suspension support 1, first
Middle part suspension holdfast the 3, second middle part suspension holdfast 5, rear suspension support 7, leaf spring 2 front end is provided with grasswort 4, in grasswort 4
Lining set 10, equalizer bar 6 rear end of riser the 9, first middle part suspension holdfast 3 of front suspension support 1, the second middle part suspension holdfast
5 equalizer bar 6 rear end is machined with pin shaft hole, the equalizer bar of riser the 9, first middle part suspension holdfast 3 of front suspension support 1 respectively
6 rear ends, equalizer bar 6 rear end of the second middle part suspension holdfast 5 pass through described pin shaft hole and bearing pin 11 respectively with leaf spring 2
Front end is hinged, and equalizer bar 6 front end of the first middle part suspension holdfast 3, equalizer bar 6 front end of the second middle part suspension holdfast 5, rear portion hang
The riser 9 of hanging bracket 7 is slidably connected with leaf spring 2 rear end respectively, can freely extend after leaf spring 2 is loaded.
In vehicle frame manufacturing process by suspension holdfast 5 in the middle part of suspension holdfast 3, second in the middle part of front suspension support 1, first,
Rear suspension support 7 is welded on vehicle frame main longitudinal grider 15, and axle assembly is fabricated separately, axle assembly comprise vehicle bridge, tire, by many
The steel plate spring assembly of individual leaf spring 2 composition, wheel cylinder and other attached smallclothes, operate on Special station, the
Pin shaft hole that the front end grasswort 4 of the leaf spring 2 of one row's axle assembly is aligned on the riser 9 of front suspension support 1 simultaneously penetrates pin
Axle 11, the rear end of leaf spring 2 enters in the front end notch of equalizer bar 6 of the first middle part suspension holdfast 3, penetrates leaf spring and stops spiral shell
Bolt 8, loads relevant position other each axle assemblies of arranging successively in the same way, tightens each bearing pin nut and plate by technical requirements
Spring stops the nut of bolt 8.
Referring to Fig. 5, in existing suspension, the front end of pull bar 12 connects hanger 13, and the rear end of pull bar 12 connects support watt 14,
The front end grasswort 4 of the leaf spring 2 of the present invention instead of effect in suspension for the pull bar 12, therefore eliminates rod assembly
And parts associated there, structure is simple, is easy to operate, amount of parts reduces, significantly mitigates light weight, reduces life
Produce cost, and non-maintaining, meet semitrailer lightweight requirements, solve existing semitrailer in use because pull bar gets loose
The problem leading to vehicle bridge sideslip and tyre irregular wear occur.
The foregoing is only the preferably feasible embodiment of the present invention, not thereby limit to the interest field of the present invention,
The equivalence changes that all utilization description of the invention and its accompanying drawing content are made, are both contained within the interest field of the present invention.
