Description
Technical field
The utility model relates to heavy-duty car transmission technical fields, are related to heavy off-road vehicle field, and in particular to a kind of
Auxiliary supporting device for gearbox.
Background technique
Currently, the transmission auxiliary support of heavy-duty car is connected with generally by connecting plate and gearbox, connection
Plate is connected by rubber block with supporting beam, is connected by bracket with frame inside face at left and right sides of supporting beam, this scheme disadvantage exists
In: when vehicle pitch gearbox is swung left and right, especially heavy off-road vehicle, rubber block be easy to produce compressive deformation from
And gap is generated between supporting beam and rubber block, it is easy to cause connection bolt to be cut by shear stress or so.
Summary of the invention
Problem to be solved in the utility model is to provide the gearbox auxiliary of a kind of enhancing supporting beam and gearbox reliability
Support device.
The utility model is achieved through the following technical solutions:
A kind of auxiliary supporting device for gearbox, including lower bracket assembly, supporting beam and two rubber blocks, the supporting beam
Both ends pass through rubber block respectively and are connected on the lower bracket assembly, and the lower bracket assembly is fixed on longitudinal beam, described
Supporting beam is hinged with gearbox hanger, and the upper side of gear box casing is fixedly connected on the downside of the gearbox hanger.
Further, the gearbox hanger includes bottom plate and two pieces of set squares, and two pieces of set squares are fixed on vertically
The upper side of the bottom plate, the axis hole of face is respectively equipped on two pieces of set squares, and two pieces of set squares pass through pin shaft and cut with scissors
It connects in the middle position of the supporting beam；The bottom plate is fixedly connected with the gear box casing upper side by two bolts.
Further, the lower bracket assembly includes two symmetrical lower bracket units, each lower bracket unit by
Bracket vertical plate, bracket sealing plate, connecting plate, bracket bent plate and bracket plate muscle are welded, and the connecting plate is located at branch erection
Plate upper end, the connecting plate have inclination angle；The supporting beam is arcuate recess steel construction.
Acquired beneficial effect is the utility model compared with prior art:
1, gearbox and supporting beam are hinged, release rotary freedom of the gearbox along vehicle forward direction, reduce speed change
Case is transmitted to the torque in supporting beam, relatively reliable between supporting beam and gearbox, improves the ride comfort of vehicle and becomes support
The service life of beam;
2, compared with conventional gearbox suspension, gearbox position is can be improved in lower bracket assembly, and gearbox improves whole
The passability and stability of vehicle;
3, the utility model reliable performance, convenient to install and maintain, structure is simple, and versatility is extremely strong, is worthy to be popularized and uses.

Specific embodiment
With reference to the accompanying drawing to the further details of explanation of the utility model.
A kind of auxiliary supporting device for gearbox as shown in Figs. 1-3, including lower bracket assembly 7, supporting beam 4 and two rubber blocks
3 .The lower bracket assembly 7 includes two symmetrical lower bracket units, and each lower bracket unit is by bracket vertical plate 9, bracket
Sealing plate 10, connecting plate 8, bracket bent plate 11 and bracket plate muscle 12 are welded.The lower bracket assembly 7 is bolted connection
On longitudinal beam 2.The connecting plate 8 is located at 9 upper end of bracket vertical plate, and the connecting plate 8 has inclination angle, two rubber
Block is fastened by bolts part respectively and is fixed on two connecting plate upper surfaces.The supporting beam 4 is arcuate recess steel construction, supporting beam
Both ends part be bolted respectively be fixedly connected on above two rubber blocks.The intermediate position of the supporting beam 4 is hinged with change
Fast case hanger 5, specifically, the gearbox hanger 5 includes bottom plate 51 and two pieces of set squares 52, two pieces of set squares pass through weldering
The upper side that mode is fixed on the bottom plate vertically is connect, is respectively equipped with the axis hole of face on two pieces of set squares, described two pieces
Set square is hinged on the middle position of the supporting beam 4 by pin shaft 6.Pin shaft one end has screw thread and shoulder, guarantees that nut is beaten
Gearbox hanger can also be rotated around pin shaft while tight.The bottom plate is fixedly connected with 1 shell of gearbox by two bolts
Upper side.
For the utility model compared with conventional gearbox suspends, it is big to solve overall dimensions, positions high gearbox space layout
The problem of, while supporting gearbox, freedom degree of the gearbox along vehicle forward direction is released, reduces gearbox transmitting
Torque on to supporting beam solves the problems, such as that the gear box suspension service life is short, improves the passability and stability of vehicle.This reality
With novel reliable performance, convenient to install and maintain, structure is simple, is worthy to be popularized and uses.
The utility model the embodiment above, is merely illustrative, be not it is only, it is all in the scope of the utility model
Or the change in equivalent the scope of the utility model is surrounded by the utility model.
