Abstract
A tractor gearbox control mechanism includes a gear shifting handle, a handle bracket, a gear shifting flexible shaft, a gear selecting flexible shaft, a flexible shaft bracket, a gear selecting plate, a gear shifting rocker arm, a gear selecting cross rod and a T-shaped shaft universal coupling, wherein the gear shifting handle is fixedly connected with the T-shaped shaft universal coupling, the T-shaped shaft universal coupling is mounted on the handle bracket, and the gear shifting handle can swing horizontally as well as back and forth relative to the handle bracket; screwed pipes at the two ends of the gear shifting flexible shaft and the gear selecting flexible shaft are fixed on the handle bracket and the flexible shaft bracket respectively and connected with the gear shifting handle, the gear selecting plate and the gear shifting rocker arm through spherical hinge pairs; and the gear selecting plate is mounted on the flexible shaft bracket, and the gear selecting cross rod is mounted on the gear selecting plate and can horizontally move. By adopting the mechanism, three groups of gear selecting positions and two shifting positions for every group, namely, six gear choices are realized, thereby satisfying the gear shifting requirements of multi-gear gearboxes. The gear shifting handle, the handle bracket are connected with the flexible shaft bracket and the gear selecting plate which are arranged on the gearbox body through the flexible shaft, and the tractor gearbox control mechanism has reasonable arrangement, and is convenient to use.
Description
Technical field
The utility model belongs to the tractor field, relates to a kind of gear box of tractor operating mechanism.
Background technique
At present, that produces at home is various than on the big-power tractor, and its gearbox shifting operating mechanism is most to adopt mechanical rod member to connect.Adopt this operating mechanism to need the loaded down with trivial details mechanical transmission route of a cover, introduce lever piece member in the operator cabin, arrange to complete machine and bring certain difficulty.Simultaneously, because the operating mechanism component universality is relatively poor between each type, thereby manufacturing, assembling, maintenance and user cost have been increased.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 usage requirement of current tractor.
The model utility content
The purpose of the utility model be to provide a kind of simple in structure, make things convenient for the gear box of tractor operating mechanism that complete machine is arranged, component universality is high, to satisfy the usage requirement of wheeled tractor.
The technological scheme of the utility model is: the gear box of tractor operating mechanism comprises: shift handle, handle bracket, gearshift flexible axle, block selecting flexible axle, flexible axle support, block selecting plate, gearshift rocking arm, block selecting cross bar, stub axle universal joint; Shift handle is fixedly connected with the stub axle universal joint, and the stub axle universal joint is contained on the handle bracket, shift handle with respect to handle bracket can about, swing; The screwed pipe at gearshift flexible axle, block selecting flexible axle two ends is separately fixed on handle bracket and the flexible axle support, links to each other through typed ball bearing pair with shift handle, block selecting plate, gearshift rocking arm; The block selecting plate is installed on the flexible axle support, and the block selecting cross bar is installed on the block selecting plate, and the block selecting cross bar can be left, move right.
The gearshift rocking arm can rotate around the rocking arm axle center.
It is indoor that handle bracket is installed on tractor driving.
The flexible axle support is installed on the gear box of tractor body.
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 support, gearshift plate on being arranged in shift handle, the handle bracket of any suitable location in the operator cabin and being arranged in gearbox casing are connected through flexible axle.Rationally distributed, easy to use.Flexible axle is the higher professional component factory product of socialization, and cost is low, and versatility is high, is prone to realize general between different type of machines receive user's favor deeply.

Fig. 2 is the right side block selecting position assumption diagram of the utility model gear box of tractor operating mechanism.
Embodiment
Gear box of tractor operating mechanism shown in Fig. 1 comprises shift handle 1, handle bracket 2, gearshift flexible axle 3, block selecting flexible axle 4, flexible axle support 5, block selecting plate 6, gearshift rocking arm 7, block selecting cross bar 8, stub axle universal joint 9.Shift handle 1 is fixedly connected with stub axle universal joint 9, and stub axle universal joint 9 is contained on the handle bracket 2, shift handle 1 with respect to handle bracket 2 can about, swing; It is indoor that handle bracket 2 is installed on tractor driving; Flexible axle support 5 is installed on the gear box of tractor body; The screwed pipe at gearshift flexible axle 3, block selecting flexible axle 4 two ends is separately fixed on handle bracket 2 and the flexible axle support 5; Link to each other through typed ball bearing pair with shift handle 1, block selecting plate 6, gearshift rocking arm 7, thereby move through can realize the shifting gears gearshift of rocking arm 7 of manipulation shift handle 1 in operator cabin.Block selecting plate 6 is installed on the flexible axle support 5, and block selecting cross bar 8 is installed on the block selecting plate 6.Block selecting cross bar 8 can be left, move right, total three block selecting positions, left, center, right, and gearshift rocking arm 7 can rotate around the rocking arm axle center when each position, can realize two drive ranges.
As shown in Figure 1; When manipulation shift handle 1 mediates; But be positioned at middle block selecting position through the block selecting cross bar 8 on block selecting flexible axle 4 Panels 6; Handle shift handle 1 move forwards or backwards this moment, then can handle gearshift rocking arms 7 before the pitman arm shaft mind-set or rotate backward through 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 location right when handling gear shift operating rod 1; The block selecting cross bar 8 that can handle on the block selecting plate 6 through block selecting flexible axle 4 is moved to the left and arrives block selecting position, left side; Handle shift handle 1 to front or rear motion this moment, then can handle gearshift rocking arms 7 before the pitman arm shaft mind-set or rotate backward through gearshift flexible axle 3, thus two drive ranges can realize block selecting position, right side the time.
Two drive ranges in the time of also can realizing block selecting position, left 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.
