Abstract
A kind of hydraulic damping balanced type swinging axle for loader, belongs to loader technical field of structures.Its architectural feature is to be provided with tripod at the lower middle part of loader frame, lower central part at tripod is shaped with the axis hole of axis hole and axle center and is hinged by bearing pin, being connected in the end with the piston rod of left and right piston cylinder separately below at the two ends, left and right of vehicle frame, the lower end of left and right piston cylinder is connected with vehicle bridge by bolt respectively.The structure of left and right piston cylinder is to be constituted shoe cream room and working chamber by double-deck cylinder body, it is shaped with in the bottom of double-deck inboard wall of cylinder block and fluid can only be flowed to the circulation check valve of shoe cream room by working chamber and fluid can only be flowed into by shoe cream room the compensation check valve of working chamber, the outer wall of cylinder body is shaped with oil filler point, the top cover of piston cylinder is shaped with passage.Advantage is to have employed hydraulic damping balance device, has good cushioning effect, reduces impact shock, adds the stationarity that loader travels, extends the service life of parts.
Description
Technical field
The invention belongs to loader structure-design technique field, be specifically related to a kind of hydraulic damping for loader
Balanced type swinging axle.
Background technology
In recent years, along with the fast development of construction machinery industry, improvement and the safety to engineering truck structure technology
The aspects such as property comfortableness it is also proposed higher requirement.But the swing vehicle axle of loader is still adopted the most both at home and abroad
Be vehicle bridge and vehicle frame is rigid contact (as shown in Figure 1), when vehicle travels on uneven road surface, road
The impact facing complete machine is very big, and loader vehicle bridge run-off the straight easily causes car body unstability and increases driver
Fatigue and fear, and then stationarity, comfortableness, the service life of vehicle component and the row to vehicle
Car safety all brings considerable influence.
Summary of the invention
It is an object of the invention to provide the hydrocushion type swing vehicle axle of a kind of new structure, can effectively overcome existing
Shortcoming with the presence of technology.
The object of the present invention is achieved like this: as shown in Figure 2,3, and its architectural feature is the car at loader
3 ' times middle parts of frame are provided with tripod 4 ', and the lower central part at tripod 4 ' is shaped with in the middle part of axis hole and vehicle bridge 2
Axis hole by bearing pin 5 hinged, the two ends, left and right of vehicle frame 3 ' separately below with left and right piston cylinder 8,8 '
Piston rod end be connected, the lower end of left and right piston cylinder 8,8 ' is connected with vehicle bridge 2 by bolt respectively,
Vehicle frame 3 ' is with bearing pin 5 as the centre of gyration, and angle of oscillation allows between 10 °～15 °.Left and right piston cylinder 8,8 '
Being to be constituted working chamber 13 and shoe cream room 12 by double-deck cylinder body 9, the lower portion at the inwall of double-deck cylinder body 9 is shaped with
Can only by fluid by working chamber 13 flow into shoe cream room 12 circulation check valve 16 and can only be by fluid by shoe cream room
The 12 compensation check valves 15 flowing to working chamber 13, the outer wall at cylinder body 9 is shaped with oil filler point 14, at piston cylinder
Top cover on be shaped with passage 17 piston back cavity 18 be connected with air.
Advantages of the present invention and good effect be:
1, the adaptive adjustment loader frame of present invention energy is relative to the position of vehicle bridge, it is ensured that putting down of vehicle frame
Stability, improves driver-operated comfort level simultaneously.
2, the present invention makes the tire of loader remain good contacting with ground, adds tire and ground
The adhesive force in face, it is ensured that vehicle is the work of normal table under complex road condition.
3, the present invention alleviates the impact because of Uneven road to vehicle frame effectively, improves vehicle component
Service life and the safety of driving.
4, present invention employs hydraulic damping balance device, there is good cushioning effect, optimize and improve
Loader service behaviour under severe conditions.
Accompanying drawing explanation
Fig. 1 is the swing axle structure chart that prior art uses.
Fig. 2 is the hydraulic damping swing axle structure drawing of device that the present invention uses.
Fig. 3 is the piston cylinder structure figure that swing vehicle axle of the present invention uses.
In the drawings: 1-wheel of loading machine, 2-vehicle bridge, 3,3 '-vehicle frame, 4 ,-sub frame, 4 '-three
Corner bracket, 5-bearing pin, 6-buting iron, 7-ground, 8,8 '-left and right piston cylinder, 9-bilayer cylinder body, 10-
Piston rod, 11-piston, 12-shoe cream room, 13-working chamber, 14-oil filler point, 15-compensates check valve,
16-circulates check valve, 17-passage, 18-piston back cavity.
Detailed description of the invention:
As shown in Figure 2,3, when loader uneven road surface travel, as vehicle bridge left end wheel run into barrier (or
Right-hand member runs into mud pit) when being lifted, the piston rod of the left piston cylinder 8 being arranged on vehicle bridge 2 upper left quarter can be pressed
Contracting, the volume of working chamber 13 reduces, internal oil pressure raises, under this kind of state, left end cylinder efficient chamber
Fluid runs through the circulation check valve 16 of bottom to shoe cream room 12 draining.Meanwhile, vehicle bridge 2 it is arranged on right
The piston rod of the piston cylinder 8 ' on top can extend, and its working chamber 13 volume increases, internal oil pressure reduces,
Under this kind of state, the oil of the shoe cream room of right piston cylinder is put down to working chamber 13 repairing by compensating check valve 15
Weighing apparatus vehicle frame.After left and right wheels lands simultaneously, two ends operating pressure be rapidly reached balance, vehicle bridge swung,
Vehicle frame then held stationary.
