Abstract
The utility model discloses a power transmission mechanism of a tractor. The power transmission mechanism of the tractor comprises that installation of a transmission system is decreased, a driver seat is moved downwards, shaking is reduced in movement, and driving is comfortable. Because the installation of the transmission system is decreased, the defect that an output of a transmission device of a branch power box is not consistent with the height of a walking transmission shaft is avoided, and the transmission device of the branch power box is consistent with the height of the walking transmission shaft. A belt transmission system is improved so that a rear power output shaft is arranged on the central position and convenient for a rotary cultivator to match with. A front power output shaft belt wheel I is increased, so that a traditional two-direction power transmission is increased to three-direction power transmission, and the power transmission mechanism is multifunctional and standardized. The power transmission mechanism of the tractor is characterized in that the three-direction power transmission is adopted in the power transmission mechanism, the power transmission mechanism is provided with a belt wheel group, the belt wheel group is arranged of triangle structure, so that the rear output shaft is arranged on the central position, and the inferior of the branch power box and a driving walking shaft are transmitted horizontally. Three improvements are adopted, so the shortcomings of an existing power transmission mechanism are avoided, the power transmission mechanism of the tractor is reasonable, reliable in performance, multifunctional and standardized.

The utility model is installed decline to transmission system on the basis of existing tractor dynamic power transmission mechanism, driver's seat is moved down, and rocks when reducing walking, makes driving more comfortable; Descend because transmission system is installed, avoid the transmission device output and the inconsistent defective of walking transmission axle height of sub-power case, make the transmission device of sub-power case consistent with walking transmission axle height; Improve belt drive system, make rear power output shaft be in the center, the rotovator coupling of being convenient to configure; Increase a front power takeoff pulley I, also make two traditional direction power transmissions be increased to three direction power transmissions.Specific as follows:
A kind of tractor dynamic power transmission mechanism, it comprises, rear power output shaft, reduction box, drive pulley, driven pulley, gearbox, sub-power case, brake hub, little drive pulley, little driven pulley, turner, front power take-off.Power transmission mechanism is installed on the vehicle frame, characterized by further comprising:
Power transmission is three directions, and its three direction is respectively: front power take-off can connect grain header; Rear power output shaft can connect rotovator; The power-driven walking wheel of sub-power case output.
Power transmission mechanism is arranged on the described vehicle frame, and transmission power is supplied with by diesel engine, through the transmission of belt pulley set, the device of forward and backward output shaft and sub-power case is rotated, and realizes work done; The rear output shaft design need not reequip the rotovator of standard in the center, makes more standardization of mechanism; Front power take-off connects grain header makes mechanism's multifunction; The gearbox that is installed in the mechanism reduces, and driver's seat is reduced, and reduces to rock with making to drive the parallel design of walking axle, reduces manufacturing cost;
Three of described belt pulley set are triangularly arranged; In two driven pulleies, built-in arrangement of clutch is housed, but the power of the forward and backward power take-off of separate or merge.
Described rear output shaft design makes things convenient for the rotovator of Application standard in center, tractor back, makes the traction standardization.
The parallel design of described driving walking axle, reduce because of oblique shaft need more be folded to the axle cost; Reduce and make and maintenance cost.
The power transmission mechanism of above structure is provided with the mechanism reasonable and more more reliable than existing power transmission mechanism, has set up front power take-off, can connect grain header effectively the tractor multifunction; The belt pulley set of setting up can make things convenient for the driving belt dress and tear open except rising the clutch action, is convenient to maintenance.Above improvement makes more standardization of power transmission mechanism.
