Description
Technical field
The utility model relates to balancing suspension field, especially a kind of heavy-duty car combined frame equalizing type of suspension is total
At.
Background technique
Currently, the equalizing type of suspension assembly high failure rate that heavy-duty car uses, maintenance cost is big, is mainly manifested in used
Balance shaft is monoblock type cambered axle, and monoblock type cambered axle is often easy to happen fracture during the work time, while there is also such as balance shafts
The problems such as spherical bearing for being used to install balance shaft in shell is easily damaged, and balance shaft support is easy to crack；How above-mentioned market is improved
Failure reduces maintenance cost, adapts to market demands, it has also become producer urgent problem.
Utility model content
The purpose of this utility model designs a kind of heavy-duty car combined frame equalizing type of suspension assembly, heavy to improve
The service life of the equalizing type of suspension assembly of automobile.
To achieve the above object, the utility model uses following technical scheme:
A kind of heavy-duty car combined frame equalizing type of suspension assembly, including balance shaft, balance shaft support and balance shaft housing；
The balance shaft includes two symmetrical bracing strut assemblies, and the bracing strut assembly includes the axis branch that center is equipped with the first mounting hole
Frame, and pass through the spindle nose in interference fit the first mounting hole of indentation；The end of the spindle nose and bracing strut weld, described in two
Bracing strut assembly spindle nose with one heart and towards opposite；Two sides up and down on the bracing strut in the first mounting hole are symmetrically arranged with
Two mounting holes and third mounting hole, and second mounting hole and third mounting hole and the hole of the first mounting hole be to identical, two
Multi-diameter shaft is pressed with by interference fit between second mounting hole of the bracing strut assembly, bracing strut described in two is total
At third mounting hole between downstairs axis is pressed with by interference fit, the both ends of the upper multi-diameter shaft and downstairs axis are logical
Cross nut and opening pin locked.
Further, the balance shaft housing is provided with bimetal liner, and the spindle nose is protruded into balance shaft housing and served as a contrast with bimetallic
Set is slidably matched.
It further, further include support base, the upper end of the support base passes through bolt and balance axis connection, the lower end of support base
It is connect by bolt with balance shaft support.
The utility model has the advantage that as follows: traditional monoblock type balance shaft assembly is improved to by the utility model
Combined framework type balance shaft assembly can be processed directly on existing, guarantee the concentric of both ends spindle nose, be not required to produce whole
Body formula balance shaft mold, saves production cost, and the balance shaft of combined framework type is compared with monoblock type balance shaft, and structure is more firm,
It is not susceptible to be broken；It is simultaneously bimetal liner by both ends balance shaft housing Internal Spherical Surface bearing replacing, the straight of balance shaft can be increased
Diameter connects balance shaft and balance shaft support using support base, internal bolt looseness is prevented, to prevent the vibration of spring block；
The utility model solves balance shaft caused by the equalizing type of suspension assembly of conventional heavy-duty automobile and breaks, spherical bearing damage, balance
Bracing strut problem easy to crack improves the bearing capacity and service life of equalizing type of suspension assembly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of balance shaft.
Specific embodiment
The utility model is described further with reference to the accompanying drawing:
A kind of heavy-duty car combined frame equalizing type of suspension assembly shown in referring to Fig.1, including balance shaft 1, balance shaft branch
Frame 2 and balance shaft housing 3.
Referring to shown in Fig. 2, the balance shaft 1 includes two symmetrical bracing strut assemblies, during the bracing strut assembly includes
The heart is equipped with the bracing strut 4 of the first mounting hole 11, and passes through the spindle nose 5 in interference fit the first mounting hole 11 of indentation.The axis
First 5 end and bracing strut 4 weld, and the spindle nose 5 of bracing strut assembly described in two is with one heart and towards opposite.
The second mounting hole 12 and third mounting hole are symmetrically arranged in the two sides up and down of the first mounting hole 11 on the bracing strut 4
13, and second mounting hole 12 and third mounting hole 13 and the hole of the first mounting hole 11 are to identical, bracing strut described in two
Multi-diameter shaft 6, the third of bracing strut assembly described in two are pressed with by interference fit between second mounting hole 12 of assembly
It is pressed with downstairs axis 7 by being interference fitted between mounting hole 13, the both ends of the upper multi-diameter shaft 6 and downstairs axis 7 pass through
Nut 8 and split pin 9 are locked, to two bracing strut assemblies are connected as one to form combined framework type balance shaft, the frame
The more traditional integral one-piece crankshaft of axis has higher intensity, is not susceptible to be broken.
The balance shaft housing 3 is provided with bimetal liner 10, the spindle nose 5 with after the peg-in-hole assembly on balance shaft support 2,
It protrudes into balance shaft housing 3 and is slidably matched with bimetal liner 10.Traditional ball bearing is changed to bimetal liner by the utility model,
The diameter that balance shaft can be increased improves the intensity of balance shaft.
The loosening of internal-flange bolt in order to prevent is also additionally arranged support base in the present embodiment to prevent the vibration of spring block
14, the upper end of the support base 14 is connect by bolt with 5 end of spindle nose of balance shaft 1, and the lower end of support base 14 passes through bolt
It is connect with balance shaft support 2.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
The various changes and improvements that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines
In range.
