Abstract
The utility model relates to a tractor final drive device and especially relates to a novel final drive assembly for a tractor front axle. The novel final drive assembly for the tractor front axle has following beneficial effects: due to the increase in the installation distance between a vertical shaft sleeve pipe and a hub reduction gear assembly, the distance from a center of the hub reduction gear assembly to the front axle is increased; and in this way, problems of a tractor front axle drive oil seal such as proneness to damage and oil leakage are easily and effectively overcome and usability of the overall tractor front axle is thus enhanced.
Description
Technical field
The utility model relates to a kind of tractor end driving device, particularly a kind of Novel tractor propons end drive assembly.
Background technology
Since China reform and opening-up, national economy obtains rapid growth, has become the main flow of the current industrial development of China with " scientific and technical innovation, autonomous innovation ", and China's industry is progressively to intensive style, energy-saving and emission-reduction, the future development of low-carbon (LC).Farm tractor front axle is one of important drive disk assembly of trac., it is drive axle and steeraxle, plays a part supporting trac. load, and load is passed to wheel, therefore, its overall performance has decisive role for the safety and reliability of whole trac..In the market and the farm tractor front axle produced of my company, mostly be the dual-purpose propons of floods and droughts, but through me company's market study and user feedback discovery, the dual-purpose propons of this floods and droughts, the general ground clearance of its front axle centre is lower, this just causes trac. in the process of moving, propons is easily encountered by more ground foreign material, particularly when trac. is in the deep working environment of some mud, because propons is liftoff lower, long-term muddy water work, can cause propons intermediate transmission oil sealing to be damaged by the foreign material in muddy water, thus loss of seal effect; And the driven oil sealer of propons is all high-speed oil seal, in work, in high speed rotating state, cause leakage of oil herein maximum.In order to address the above problem, scientific research personnel of the same trade is by updating oil sealing quality, and the packing technique of raising oil sealing, but all can not tackle the problem at its root.My scientific research personnel of company, by investigating in large quantities, studying, has found a kind of simple and effective solution to the problems described above, although obtained technically, some are progressive, still exist the technical barrier not yet overcoming in practice.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, a kind of Novel tractor propons end drive assembly is provided, by improving the mounting distance between vertical shaft sleeve pipe and wheel reduction gear assembly, improve the distance of wheel reduction gear assembly center to front axle centre, thereby simple and effectively overcome the fragile and Leakage of dilatory propons driven oil sealer, and then improve the overall in-use performance of farm tractor front axle.
The utility model solves the technical scheme that its technical matters adopts: contain spindle arm, transmission housing, transmission vertical shaft, vertical shaft sleeve pipe, transmission output shaft, transmission gear, vertical shaft gear, in transmission housing, be provided with vertical shaft sleeve pipe, the length of vertical shaft sleeve pipe is 286mm, transmission vertical shaft is installed in vertical shaft sleeve pipe, the length of transmission vertical shaft is 330mm, the two ends up and down of transmission vertical shaft are all installed with vertical shaft gear, the vertical shaft gear of upper end is meshed and is connected with the transmission shaft of propons, the vertical shaft gear of lower end is meshed and is connected with the transmission gear on wheel reduction gear assembly, the top of transmission vertical shaft is connected with one end of spindle arm, transmission gear center on wheel reduction gear assembly is installed with transmission output shaft, and the distance of the line of centers of this transmission output shaft and front axle propeller shaft line of centers is 105mm.
The know-why that the utility model adopts is: the front axle centre line of old-fashioned propons generally is 10mm (as shown in Figure 1) to the distance of tire line of centers, this distance makes propons ground clearance less, in the time that trac. is worked in the deep environment of muddy water, the driven oil sealer of propons is easy to be damaged by the foreign material in muddy water, loss of seal effect, and then cause a large amount of leakage of oils in driven oil sealer place.This Novel front axle end drive assembly will increase vertical shaft sleeve length of tube, by the 226mm of original vertical shaft sleeve pipe, be increased to 286mm, and by the mounting flange face at itself and the front axle propeller shaft center 15mm that moves up; Increase the length of transmission vertical shaft simultaneously, the 235mm of original transmission vertical shaft is increased to 330mm, finally making the line of centers of transmission output shaft and the distance of front axle propeller shaft line of centers is 105mm.The setting of this increase distance is through a large amount of market studys and user feedback, in the situation that not changing the original usability of propons, safety and aesthetic property, and the preferred version obtaining.
The utility model beneficial effect is: by improving the mounting distance between vertical shaft sleeve pipe and wheel reduction gear assembly, improve the distance of wheel reduction gear assembly center to front axle centre, thereby simple and effectively overcome the fragile and Leakage of dilatory propons driven oil sealer, and then improve the overall in-use performance of farm tractor front axle.
Brief description of the drawings
Fig. 1 is old-fashioned farm tractor front axle structural representation;
Fig. 2 is a kind of Novel tractor propons end drive assembly structural representation;
In the drawings: 1. spindle arm, 2. transmission housing, 3. transmission vertical shaft, 4. vertical shaft sleeve pipe, 5. transmission output shaft, 6. transmission gear, 7. vertical shaft gear.
Detailed description of the invention
In conjunction with the accompanying drawings and embodiments the utility model to be further described below:
In Fig. 2, in transmission housing 2, be provided with vertical shaft sleeve pipe 4, the length of described vertical shaft sleeve pipe 4 is 286mm, transmission vertical shaft 3 is installed in vertical shaft sleeve pipe 4, the length of described transmission vertical shaft 3 is 330mm, and the two ends up and down of transmission vertical shaft 3 are all installed with vertical shaft gear 7, and the vertical shaft gear 7 of upper end is meshed and is connected with the transmission shaft of propons, the vertical shaft gear 7 of lower end is meshed and is connected with the transmission gear 6 on wheel reduction gear assembly, and the top of transmission vertical shaft 3 is connected with one end of spindle arm 1; Transmission gear 6 centers on wheel reduction gear assembly are installed with transmission output shaft 5, and the distance of the line of centers of this transmission output shaft 5 and front axle propeller shaft line of centers is 105mm.
This Novel front axle end drive assembly will increase vertical shaft sleeve pipe 4 length, by the 226mm of original vertical shaft sleeve pipe 4, be increased to 286mm, and by the mounting flange face at itself and the front axle propeller shaft center 15mm that moves up; Increase the length of transmission vertical shaft 3 simultaneously, the 235mm of original transmission vertical shaft 3 is increased to 330mm, finally making the line of centers of transmission output shaft 5 and the distance of front axle propeller shaft line of centers is 105mm.The setting of this increase distance is through a large amount of market studys and user feedback, in the situation that not changing the original usability of propons, safety and aesthetic property, and the preferred version obtaining.Novel front axle end drive assembly after improvement makes front axle centre improve 95mm to the distance on ground than old-fashioned propons, has simple and effectively overcome the fragile and Leakage of dilatory propons driven oil sealer.
