The control mechanism can realize three gear choosing positions and two gear shifting positions in each gear choosing position, thereby achieving six gear options and satisfying the gear shifting requirements of multi-gear gearbox.
Description
Technical field
The utility model belongs to the trac. field, relates to a kind of gear box of tractor flexible axle shift control mechanism.
Background technology
At present, that produces at home is various than on the large tractor, and its gearbox shifting steering unit is most to adopt mechanical rod member to connect.Need the loaded down with trivial details mechanical drive route of a cover, lever piece member is introduced in the operator's compartment, arrange to complete machine and bring certain difficulty.Simultaneously, because the steering unit component universality is relatively poor between each type, thereby increased manufacturing cost.Therefore be necessary to develop a kind of simple in structure, make things convenient for the shift control mechanism that complete machine is arranged, component universality is high, to satisfy the operating needs of current trac..
The utility model content
The purpose of this utility model be to provide a kind of simple in structure, make things convenient for the gear box of tractor flexible axle shift control mechanism that complete machine is arranged, component universality is high, to satisfy the operating needs of wheel-tire tractor.
The technical solution of the utility model is: gear box of tractor flexible axle shift control mechanism mainly comprises gear shift operating rod, flexible axle upper holder, gearshift flexible axle, block selecting flexible axle, flexible axle lower fixed frame, gearshift toggle mechanism, gearshift rocking arm, Hooke's joint.Link to each other by a Hooke's joint between gear shift operating rod and flexible axle upper holder, gear shift operating rod with respect to the flexible axle upper holder can about, swing, the flexible axle upper holder is installed in the operator's compartment.Flexible axle lower fixed frame, gearshift toggle mechanism are installed on the gear box of tractor body.Gearshift is equipped with the gearshift rocking arm on the toggle mechanism, and the gearshift rocking arm can be left, move right; Gearshift flexible axle, block selecting flexible axle are captiveed joint with flexible axle upper holder, flexible axle lower fixed frame respectively, link to each other by typed ball bearing pair with gear shift operating rod, gearshift toggle mechanism, gearshift rocking arm.
Total three the block selecting positions, left, center, right of gearshift rocking arm can be rotated around the rocking arm axle center when each position, can realize two drive ranges.
The utility model can reach following beneficial effect: adopt the utility model can realize three groups of block selecting positions and every group of two drive ranges, can realize six gears selections altogether, satisfy many gears gearbox shifting demand.Flexible axle lower fixed frame, gearshift toggle mechanism on being arranged in gear shift operating rod, the flexible axle upper holder of any suitable location in the operator's compartment and being arranged in gearbox body are connected by flexible axle.Rationally distributed, easy to use.Flexible axle is the higher professional parts factory product of socialization, and cost is low, and the commonality height is easily realized general between different type of machines being subjected to user's favor deeply.

Fig. 1 is the middle block selecting position assumption diagram of the utility model gear box of tractor flexible axle shift control mechanism;
Fig. 2 is the left side block selecting position assumption diagram of the utility model gear box of tractor flexible axle shift control mechanism.
The specific embodiment
Gear box of tractor flexible axle shift control mechanism comprises gear shift operating rod 1, flexible axle upper holder 2, gearshift flexible axle 3, block selecting flexible axle 4, flexible axle lower fixed frame 5, gearshift toggle mechanism 6, gearshift rocking arm 7, Hooke's joint 8 as shown in Figure 1.2 of gear shift operating rod 1 and flexible axle upper holders link to each other by a Hooke's joint 8, gear shift operating rod 1 with respect to flexible axle upper holder 2 can about, swing, flexible axle upper holder 2 is installed in the operator's compartment.Flexible axle lower fixed frame 5, gearshift toggle mechanism 6 are installed on the gear box of tractor body, gearshift rocking arm 7 is installed on the gearshift toggle mechanism 6, gearshift rocking arm 7 can be left, move right, total three block selecting positions, left, center, right, when each position, can rotate, can realize two drive ranges around the rocking arm axle center.Gearshift flexible axle 3, block selecting flexible axle 4 are captiveed joint with flexible axle upper holder 2, flexible axle lower fixed frame 5 respectively, link to each other by typed ball bearing pair with gear shift operating rod 1, gearshift toggle mechanism 6, gearshift rocking arm 7, thereby move by in operator's compartment, handling gear shift operating rod 1 can realize the shifting gears gearshift of rocking arm 7.
As shown in Figure 1, when manipulation gear shift operating rod 1 mediates, the gearshift rocking arm 7 that can handle on the gearshift toggle mechanism 6 by block selecting flexible axle 4 is positioned at middle block selecting position, handle gear shift operating rod 1 and move forwards or backwards this moment, then can handle gearshift rocking arms 7 on the rocker shaft mind-set or rotate by gearshift flexible axle 3, thus two drive ranges in the middle of can realizing during the block selecting position.
As shown in Figure 2, be positioned at left position when handling gear shift operating rod 1, the gearshift rocking arm 7 that can handle on the gearshift toggle mechanism 6 by block selecting flexible axle 4 is moved to the left and arrives block selecting position, left side, handle gear shift operating rod 1 to front or rear motion this moment, then can handle gearshift rocking arms 7 on the rocker shaft mind-set or rotate by gearshift flexible axle 3, thus two drive ranges can realize block selecting position, left side the time.
Two drive ranges in the time of also can realizing block selecting position, right side as a same reason.
In sum, the utility model can be realized three groups of block selecting positions and every group of two drive ranges, can realize six gears selections altogether.
