Abstract
The damping front axle assembly for four-wheel tractor belongs to tractor applied in agricultural machinery industry, which is especially suitable for the four-wheel tractor. The main technology adopted by the utility model is that two standing poles are fixed on the two vehicle frames, a horizontal bar fixes and connects to the upper part of the standing pole, a plate on the lower part of the standing pole combines the vehicle frame and the standing pole, two sleeves are fixed at the two terminals of the horizontal bar, the upper part of the standing shaft is arranged in the sleeve, the hole on the lower part of the standing shaft is positioned on the shaft of the shaft base which fixed on a rocker arm, the hole on the rocker arm is arranged on the shaft of the shaft base under the plate and springs and a spring support is positioned on the standing shaft. The utility model has the advantages in that the product can reduce the vibration of tractors during driving, enhance stability of the tractor, prolong service life of tractor and improve the drivers' comfortable experience.
Description
Technical field:
The utility model belongs to the trac. field in the field machine.
Background technology:
Existing four-wheeled tractor front axle assy has two kinds of ways substantially.A kind ofly be: beam and carriage are installed together with bearing pin, are equipped with front wheel spindle on the carriage, the front-wheel on the front wheel spindle can only swing up and down, and does not have shock attenuation unit.Another kind is: directly shock attenuation unit is installed on the front-axle beam, thereby makes the front-wheel of installing on the front-axle beam have only vibration-damping function, and do not swing up and down function.These two kinds of ways all have the degree of freedom of constrained motion to a certain extent, can not play damping of vibrations fully, thus when trac. is on the way walked, seem vacillating and staggering, so unstable, to be improved the front axle assy of existing trac..
Summary of the invention:
The purpose of this utility model to design exactly a kind of can up-and-down movement, the four-wheeled tractor vibration damping front axle assy that can swing again.
The technical scheme that its technical matters that solves the utility model adopts is: fix two vertical rods on two vehicle frames, the upper end of vertical rod is with a cross bar captive joint, captive joint vehicle frame with a plate and be integral in the lower end of vertical rod with vertical rod, fix two sleeves at the two ends of cross bar, the vertical shaft upper end is contained in the sleeve, the hole of vertical shaft lower end is contained on the axle in the axle bed that is fixed on the rocking bar face, and the hole on the rocking bar is contained on the axle in the axle bed that is fixed on below the plate, and spring and spring perch are housed on the vertical shaft.
The utility model beneficial effect is: can reduce the vibration of trac. in operational process, increase the stationarity of trac., improve the service life of trac. and driver's comfort.
Description of drawings:
Fig. 1 is a front elevational schematic of the present utility model.
Fig. 2 is the schematic side view after Fig. 1 takes down wheel (15).
Fig. 3 is that the A of Fig. 1 is to scheme drawing.
The specific embodiment:
Describe details of the present utility model and service condition in detail in conjunction with Fig. 1, Fig. 2, Fig. 3.On two vehicle frames (7), fix two vertical rods (3), the upper end of vertical rod is with a cross bar (1) captive joint, captive joint vehicle frame (7) with a plate (8) and be integral in the lower end of vertical rod with vertical rod (3), fix two sleeves (20) at the two ends of cross bar (1), vertical shaft (6) upper end is contained in sleeve (20) lining, the hole of vertical shaft lower end is contained on the axle (11) of axle bed (12) lining that is fixed on rocking bar (17) face, hole on the rocking bar (17) is contained on the axle (10) that is fixed on following axle bed (9) lining of plate (8), and spring (4) and spring perch (5) are housed on the vertical shaft (6).Junction at vertical rod (3), cross bar (1) is welded with brace panel (2).Axle bed (12) is to be fixed on rocking bar (17) face with screw (18).Axle bed (9) is fixed on screw (19) below the plate (8), and axle bed (9) is two, and axle (10) also is two.Rocking bar (17) is a two boards, the both sides of every block of plate are done porose respectively, the hole on both sides is contained in respectively on two axles (10), rocking bar (17) just can rotate around axle (10), be fixed with axle bed (12) again on rocking bar (17) face, axle (11) is housed again in the axle bed, axle (11) is fitted together with the hole of vertical rod (3), so vertical shaft (6) rotates on axle (11), spring (4) and spring perch (5) are housed on the vertical shaft (6), and spring perch is fixed on the vertical shaft (6), so rocking bar (17) is when shaking, born by spring, vehicle frame (7) just can not be influenced again.Be fixed with goat's horn axle (15) cover (14) on rocking bar (17), wheel (16) is housed on the goat's horn axle (15), the upper end of goat's horn axle (15) is fixed with spindle arm (13).
Claims (1)
1, a kind of four-wheeled tractor vibration damping front axle assy, it is characterized in that: on two vehicle frames (7), fix two vertical rods (3), the upper end of vertical rod is with a cross bar (1) captive joint, captive joint vehicle frame (7) with a plate (8) and be integral in the lower end of vertical rod with vertical rod (3), fix two sleeves (20) at the two ends of cross bar (1), vertical shaft (6) upper end is contained in sleeve (20) lining, the hole of vertical shaft lower end is contained on the axle (11) of axle bed (12) lining that is fixed on rocking bar (17) face, hole on the rocking bar (17) is contained on the axle (10) that is fixed on following axle bed (9) lining of plate (8), and spring (4) and spring perch (5) are housed on the vertical shaft (6).
