Abstract
The invention relates to a tractor steering transmission device, in particular to a gear transmission device used for steering of an electric tractor. The gear transmission device comprises a shell, a first gear shaft and a second gear shaft. The first gear shaft and the second gear shaft are arranged in the shell in parallel. A first gear is arranged on the first gear shaft. A second gear and a third gear are arranged on the second gear shaft. The first gear is engaged with the second gear. An input shaft of the first gear shaft is connected with a steering wheel of the electric tractor. The third gear is engaged with a fourth gear. Through matching of the first gear on the first gear shaft and the second gear on the second gear shaft and matching of the third gear on the second gear shaft and the fourth gear, transmission between the steering wheel and front wheels of the tractor is completed; the first gear, the second gear, the third gear and the fourth gear with different tooth numbers are selected and used, so that operation is more convenient and more effortless; damage is not liable to occur by adopting gear pair transmission, and the service life of the whole device is greatly prolonged.
Description
Technical field
The present invention relates to a kind of tractor steering transmission linkage, more particularly, to a kind of tooth turned to for electrically propelled traction vehicle
Wheel transmission device.
Background technology
When common mechanical steering needs to turn to, driver applies a steering moment, the torque to steering wheel
By steering spindle input steering gear, after having deceleration transmission pair, diverted device to amplify in the steering gear of speed reduction gearing
Track rod is passed in motion after power and deceleration, then passes to the knuckle arm being fixed on knuckle, makes knuckle and its institute
The deflecting roller deflection of supporting, so as to change travel direction.At present the transmission of transmission device adopts wheel and rack phase mostly
The mode of cooperation, this kind of drive operation is laborious and fragile, and service life is short.
The content of the invention
To solve problem above, the present invention provides a kind of gear drive turned to for electrically propelled traction vehicle, the transmission
Apparatus structure is compact, good stability, easy to operate, long service life.
The technical solution used in the present invention is：A kind of gear drive turned to for electrically propelled traction vehicle, including housing,
The first gear axle and second gear axle being set in parallel in housing, it is characterised in that：The first gear axle is provided with first
Gear, the second gear axle is provided with second gear and the 3rd gear, and the first gear and second gear are meshed；It is described
The input shaft of first gear axle stretches out that housing is outer to be connected with the steering wheel of electrically propelled traction vehicle, the 3rd gear and the 4th gear phase
Engagement, drives electrically propelled traction vehicle front-drive.
Preferably, the number of teeth of the number of teeth of the first gear less than second gear, the second gear number of teeth is more than the
The number of teeth of three gears, the number of teeth of the 3rd number of gear teeth less than the 4th gear.
Preferably, the first gear axle and second gear axle are arranged in housing by bearing and bearing cap.
Preferably, the bearing cap is provided with fuel filler neck.
Preferably, the first gear is arranged on first gear axle by flat key, the second gear and the 3rd tooth
Wheel is arranged on second gear axle by flat key.
The present invention obtain beneficial effect be：The present invention is by the first gear and second gear axle on first gear axle
Second gear be engaged, the 3rd gear and the 4th gear on second gear axle is engaged, complete tractor steering wheel and front
Transmission between wheel, first gear, second gear, the 3rd gear and the 4th gear select the different numbers of teeth so that operation is more
Plus it is convenient and strength-saving, it is hardly damaged using gear auxiliary driving, greatly improve the service life of whole device.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Fig. 2 is the sectional view of Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is further described with specific embodiment.
As shown in Figure 1, 2, a kind of gear drive turned to for electrically propelled traction vehicle of the invention, including housing 1, the
One gear shaft 2 and second gear axle 3, housing 1 is provided with gear shaft installing hole, and first gear axle 2 and second gear axle 3 are mutually flat
Row is arranged in gear shaft installing hole.First gear 21, second gear axle 3 are installed with by flat key on first gear axle 2
The gear 32 of second gear 31 and the 3rd is installed with by flat key, first gear 21 and second gear 31 are intermeshed, first
The input shaft of gear shaft 2 stretches out that housing 1 is outer to be connected with the steering wheel of electrically propelled traction vehicle, and the steering wheel of operation electrically propelled traction vehicle can be with
First gear axle 2 is driven to rotate.3rd gear 32 is meshed with the 4th gear 4, and the 4th gear 4 connects with electrically propelled traction vehicle front-wheel
Connect, second gear axle 3 is rotated can pass through the driving electric tractor front-wheel steer of the 4th gear 4.
In order that steering operation is convenient laborsaving, the number of teeth of first gear 21 is less than the number of teeth of second gear 31, the
, more than the number of teeth of the 3rd gear 32, less than the number of teeth of the 4th gear 4, the concrete number of teeth can for the number of teeth of the 3rd gear 32 for the number of teeth of two gear 31
To be set according to actual vehicle model.
In order to increase the sealing of device, anti-locking apparatus wear and tear, and first gear axle 2 and second gear axle 3 pass through bearing 5
It is arranged in the gear shaft installing hole of housing 1 with bearing cap 6.Fuel filler neck, convenient addition lubricating oil are provided with bearing cap 6.
