Abstract
The utility model discloses a kind of two-wheel drive wheel-tire tractor and increase propons, comprise front hub, knuckle assembly, secondary case pipe assembly and spindle arm; The two ends of described knuckle assembly are plugged in front hub and in secondary case pipe assembly respectively, be provided with the tapered roller bearing making both rotate between described knuckle assembly and front hub, the thrust ball bearing making both rotate is set between described knuckle assembly and secondary case pipe assembly; Described spindle arm is connected with knuckle assembly and drives it to rotate.Two-wheel drive wheel-tire tractor of the present utility model increases propons, and intensity is good, and steering flexibility is good, and the ground Clearance is high.
Description
Technical field
The utility model belongs to mould applications, is specifically related to a kind of two-wheel drive wheel-tire tractor and increases propons.
Background technology
Existing two-wheel drive farm tractor front axle, for installing front-wheel, provides support the weight of trac. front portion, and shortcoming is to turn to dumb and bearing force deficiency.Used with tractor, when intertillage operation, needs the larger ground Clearance, to ensure the crossing ability of trac., maximum possible avoid damage crop, the common farm tractor front axle ground Clearance is 355mm, limits field crossing ability.
Utility model content
(1) technical matters that will solve
The technical problems to be solved in the utility model be to make two-wheel drive farm tractor front axle turn to more flexibly and bearing force strong.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of two-wheel drive wheel-tire tractor increases propons, comprises front hub, knuckle assembly, secondary case pipe assembly and spindle arm; The two ends of described knuckle assembly are plugged in front hub and in secondary case pipe assembly respectively, be provided with the tapered roller bearing making both rotate between described knuckle assembly and front hub, the thrust ball bearing making both rotate is set between described knuckle assembly and secondary case pipe assembly; Described spindle arm is connected with knuckle assembly and drives it to rotate.
Further, in described secondary case pipe assembly, a lining be enclosed within knuckle assembly is installed.
Further, described lining has two, and is positioned at the axial both sides of secondary case pipe assembly.
Further, described tapered roller bearing has two, and is positioned at the axial two ends of front hub and is symmetrical arranged.
Further, center to the distance of secondary case pipe assembly of described front hub is 425mm.
Further, described front hub is provided with a front-wheel, is provided with oblique angle between described front-wheel center and horizon.
(3) beneficial effect
Two-wheel drive wheel-tire tractor of the present utility model increases propons, by being provided with the tapered roller bearing making both rotate between described knuckle assembly and front hub, the thrust ball bearing making both rotate is set between described knuckle assembly and secondary case pipe assembly; Thus turn to and turn improve bearing force and intensity more flexibly, and while proof strength, the center height of drive wheel is increased to secondary case pipe assembly place height, improves the ground Clearance of front-wheel, obtain better field crossing ability.Front-wheel axis and ground have leaning angle, and axial location just exists radial and axial load.
Accompanying drawing explanation
Fig. 1 is the block diagram that two-wheel drive wheel-tire tractor of the present utility model increases propons;
Fig. 2 is the enlarged drawing of A in Fig. 1;
Fig. 3 is the enlarged drawing of B in Fig. 1;
1 be spindle arm, 2 be knuckle assembly in figure, 3 be secondary case pipe assembly, 4 be thrust ball bearing, 5 be tapered roller bearing, 6 be front hub, 7 be lining, 8 for front-wheel.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1-Figure 3, a kind of two-wheel drive wheel-tire tractor increases propons, comprises front hub 6, knuckle assembly 2, secondary case pipe assembly 3 and spindle arm 1; The two ends of described knuckle assembly 2 are plugged in front hub 6 and in secondary case pipe assembly 3 respectively, be provided with the tapered roller bearing 5 making both rotate between described knuckle assembly 2 and front hub 6, select circular cone to roll coro bearng 5 herein and can bear large radial weight and axial load.The thrust ball bearing 4 making both rotate is set between described knuckle assembly 2 and secondary case pipe assembly 3, select thrust ball bearing 4 herein, be applicable to bear an axial load, steering swivel position that rotating speed is lower, while keeping supporting power, what can ensure to turn to is flexible.Described spindle arm 1 is connected with knuckle assembly 2 and drives it to rotate.
A lining 7 be enclosed within knuckle assembly 2 is installed in described secondary case pipe assembly 3; described lining 7 has two; and be positioned at the axial both sides of secondary case pipe assembly 3; described lining 7 can protect knuckle assembly 2 not to be scraped off; radial weight is stressed at lining position, and can improve bearing force and flexibility ratio again.
Described tapered roller bearing 5 has two, and be positioned at the axial two ends of front hub 6 and be symmetrical arranged, because tapered roller bearing can only transmit unidirectional axial load, therefore, another symmetrical tapered roller bearing installed with it is just needed for transmitting rightabout axial load.
By above-mentioned improvement, ensure that the intensity of propons entirety, be 425mm by the center of described front hub 6 to the distance of secondary case pipe assembly 3 under the prerequisite ensureing propons intensity, improve the ground Clearance of front-wheel, obtain better field crossing ability.
Described front hub 6 is provided with a front-wheel 8, is provided with oblique angle between described front-wheel 8 center and horizon.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
