Embodiment Construction

[0013] The present invention will be further described below in conjunction with examples, but the present invention is not limited to these examples.

[0014] The main transmission control mechanism of the four-wheel tractor shaft transmission system gearbox of the present invention includes a gear handle 1 .

[0015] As the improvement of the main speed change control mechanism of the gearbox of the four-wheel tractor shaft drive system of the present invention, compared with the ordinary shifter, the lower part of the gear handle 1 of the main speed change control mechanism of the gearbox of the four-wheel tractor shaft drive system of the present invention is bent forward, and the end It is connected to the transmission group I3 that can make the shift handle 1 move vertically to the shift fork 2. The upper part of the bend is connected to the drive group II4 that can transfer the shift handle 1 to the shift fork 2 horizontally. Group I drives the shifter paddles to move l...

Abstract

The invention discloses a four-wheel tractor shaft transmission system gearbox main variable speed control mechanism. The four-wheel tractor shaft transmission system gearbox main variable speed control mechanism comprises a gear handle, a transmission set I and a transmission set II. When the gear handle longitudinally moves, a gear shifting device plate is driven to longitudinally move through the transmission set I, and when the gear handle transversely moves, the gear shifting device plate is driven to transversely move through the transmission set II. Connection is achieved through a lever part, a transmission structure is arranged between the gear handle and a gear shifting device, the gear handle is not limited on the gear shifting device, and due to transverse and longitudinal separation, in the gear shifting process, gear mistaken operating is not prone to happening.

Description

technical field [0001] The invention relates to the technical field of tractor manipulation, in particular to a main transmission control mechanism of a gearbox of a shaft drive system of a four-wheel tractor. Background technique [0002] The gear handle of the existing transmission is installed on the top of the gear changer. In order to facilitate the operation, the gear changer needs to be installed under the driver's cab to make the gear handle position within the reach of the driver. Therefore, the installation position of the gear shifter has certain limitations, that is, if the gear shifter is not installed below the cab, it will cause the tractor to be unable to be manipulated to shift gears in the cab. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention discloses a four-wheel tractor shaft drive system gearbox main shifting control mechanism. By connecting the transmission structure below the shift handle, the pro...
