Description
Technical field：
The utility model is related to a kind of pin shaft connected auxiliary supporting device for gearboxes.
Background technology：
Heavy truck is since the torque transmitted when gearbox size itself is big, weight is big and works is big, engine
Bell housing and bell housing easily fracture damage, particularly off-highway mine car, in severe working environment, due to road conditions
Difference, vibration are big, so gearbox needs to increase auxiliary support structure.
At present, the transmission auxiliary support structure of off-highway quarry tipper is mainly bolt connecting type in the market, speed change
Case Auxiliary support beam is connect by studs with gearbox, and both sides are attached again by bolt and vehicle-frame seat, in vehicle
In the case that working environment is severe, front and back wheel is often caused vacantly to bring larger chassis torsion, bolt rigidity Planar Mechanisms connect
The Auxiliary support deformation that chassis torsion is brought can not be offset by connecing, especially for haul truck, for a long time under this operating mode
Work, it may appear that the fracture of Auxiliary support beam connects the problems such as bolt fracture, gear box casing permeability, it is difficult to meet production operation
In requirement.
Utility model content：
The utility model provides a kind of pin shaft connected auxiliary supporting device for gearbox, it is simple in structure, reasonable design,
The axis pin connection of the device and buffer structure are effectively solved because the power assembly that bolt rigidity Planar Mechanisms connect band is come is crossed about
Shu Wenti reduces the transmission auxiliary support beam deformation fracture since chassis torsion is brought, connects bolt fracture, transmission housing
Phenomena such as body permeability bolt fracture, solve problems of the prior art.
Used technical solution is the utility model to solve above-mentioned technical problem：
A kind of pin shaft connected auxiliary supporting device for gearbox passes through including Auxiliary support beam and at Auxiliary support beam both ends
The frame connecting seat of first axis pin connection is equipped with buffer structure, in the lower horizontal of buffer structure at the middle part of Auxiliary support beam
Equipped with gearbox connecting seat, gearbox connecting seat is connected by buffer structure with Auxiliary support beam.
The gearbox connecting seat includes the first gearbox connecting seat being connected by buffer structure with Auxiliary support beam, the
One gearbox connecting seat is connected by the second axis pin and the second gearbox connecting seat.
The buffer structure is two sets be arranged side by side, and often set respectively includes being positioned over Auxiliary support beam upper surface and lower end
First gearbox connecting seat, two dampers are connected by two dampers in face by bolt with Auxiliary support beam.
Using the above scheme, it is simple in structure for the utility model, reasonable design, the axis pin connection of the device and buffer structure
The effective power assembly Planar Mechanisms for solving the problems, such as to come by bolt rigidity Planar Mechanisms connect band, reduce because chassis torsion is brought
Transmission auxiliary support beam deformation fracture, connection bolt fracture, gear box casing permeability bolt fracture phenomena such as.
Description of the drawings：
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the front view of the utility model.
In figure, 1, frame connecting seat, the 2, first axis pin, 3, Auxiliary support beam, 4, damper, 5, bolt, the 6, second speed change
Device connecting seat, the 7, first speed changer connecting seat, the 8, second axis pin.
Specific embodiment：
The utility model is described further with embodiment below in conjunction with the accompanying drawings：
As shown in Figs. 1-2, a kind of pin shaft connected auxiliary supporting device for gearbox including Auxiliary support beam 3 and is assisting
The frame connecting seat 1 that 3 both ends of supporting beam are connected by the first axis pin 2 is equipped with buffer structure at the middle part of Auxiliary support beam 3,
The lower horizontal of buffer structure is equipped with gearbox connecting seat, and gearbox connecting seat is connected by buffer structure with Auxiliary support beam 3.
The gearbox connecting seat includes the first gearbox connecting seat 7 being connected by buffer structure with Auxiliary support beam 3,
First gearbox connecting seat 7 is connected by the second axis pin 8 and the second gearbox connecting seat 6, is reduced firm between each connector
Property is by force constraint.
The buffer structure is two sets be arranged side by side, and often set respectively includes being positioned over 3 upper surface of Auxiliary support beam under
First gearbox connecting seat 7, two dampers 4 are connected by two dampers 4 of end face by bolt with Auxiliary support beam 3, are offset
Active force between first gearbox connecting seat 7 and Auxiliary support beam 3.
During work, due to vehicle vibration by gearbox transmission come power pass to the second gearbox connecting seat 6, by
The flexible connection of two axis pins 8 can offset a part of impact force, and remaining power passes to damping using the first gearbox connecting seat 7
Device 4, since the cushioning effect of damper 4 offsets again a part of impact force, power is transmitted to Auxiliary support from damper 4 at this time
Beam 3, then frame connecting seat 1 is passed to by Auxiliary support beam 3, pass through Auxiliary support beam 3 and the first axis pin 2 of frame connecting seat 1
Connection offset a part of impact force again, last residue very small part power, therefore the device plays the housing of gearbox
Very big protective effect also greatly reduces transmission auxiliary support beam deformation fracture, connects the problems such as bolt fracture.
Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model
In the range of shield.
Part is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.
