Abstract
The utility model relates to a differential steering device for a steering wheel, which is the improvement on a hand pushing frame and a jaw clutch control steering device of a a Gongnong 12 model walking tractor. The original machine has the defects of long machine frame, difficult steering, large labor strength, large wheel base of the front and the rear wheels of the trailer when hung by a rear hanger, and inefficacious turning. The utility model adopts a steering wheel mechanism to replace walking. A differential device of a cone gear replaces the main driving gear wheel, increasing a differential lock to improve the non-skid capability. The utility model has the advantages of short machine frame, small wheel base, flexible cornering, convenient operation, good manufacturability, and small change in the speed reducer.
Description
The utility model relates to the steering hardware of compact tractor, and particularly workers and peasants' 12 type trac. bearing circle differential steering devices are the improvement to workers and peasants' 12 type walker tractor steering hardwares.
Workers and peasants' 12 type walker tractors are a kind of simple in structure, easy and simple to handle, and horsepower is big, lightweight small farm trac..Its function that turns to is to control denture clutch artificially, causes left and right sides output speed poor, cooperates hand push swing frame to finish.This swing frame, the steering hardware shortcoming of control denture clutch is a lot:
1. frame is long, and chaufeur moves after making machine gravity, reduces the tractive force of trac..
2. long owing to frame, machine operation under the chaufeur palpus when changeing the sharp turn, labour intensity is big, and it is dumb to turn.
3. the people turns to for the control denture clutch, troublesome poeration, and control did not easily have an accident at that time.
4. when the back hung trailer do transportation use, the wheel base of complete machine was big, makes turn radius also big, and turning performance is poor.
The purpose of this utility model provides a kind of novel steering device that can overcome above-mentioned shortcoming.
Way of the present utility model is with bearing circle mechanism swing frame, utilizes the automatic output speed of box of tricks of particular design poor, thereby reaches the purpose that turns to flexibly.Box of tricks is made of bevel differential and differential locking-device.
Their working process is such, and the swing frame makes left and right sides front-wheel stressed unequal when direction mechanism, thereby forces the diff output speed poor, and trac. is turned.Differential locking-device is assemblied between diff output gear and the reducing gear, when operating the locking clutch of differential locking-device, can pin diff, drives front-wheel by force, strengthens the trac. skid resistance.
Diff is to constitute like this, by steering shaft and planet axis with two center gears and two satellite gear symmetric arrangement be assemblied in the housing of forming by left and right half housing.Planet axis is vertical with steering shaft and pass steering shaft.Right half outside is made gear forms and is meshed with the variable gear of paying on the former machine.
Differential locking-device is by left and right gear wheel shaft, left and right gear, and denture clutch, compression spring is formed, and they all are contained on the same axis.Denture clutch is by fork controls, and when closing power-transfer clutch, the left and right tooth wheel shaft is combined into an integral body, and left and right sides gear is exported with constant speed.
The utility model can be easily with throttle, and brake changes foot-operated control into.Bearing circle mechanism of the present utility model and general vehicle are similar.
The utility model is simple in structure, and frame is short, turns flexibly, and is easy to operate, drives comfortablely, and when the back hung trailer, wheel base was reduced to more than 2 meters 3 meters by original more, and turn radius is little, and operating seat can be arranged on the frame, reduces counterweight, the increase tractive force.The interior change of trac. drop-gear box is little, and the technology inheritance is good, and is easy to utilize.
Below with description of drawings embodiment:
Fig. 1 is the set-up diagram of main gear big gear wheel part in former workers and peasants' 12 type walker tractor drop-gear boxs.(1) pays variable gear, (2) main gear big gear wheel, (3) steering shaft, the denture clutch of (4) band gear.
Fig. 2 is the utility model assembly drowing.Diff by steering shaft (5) and planet axis (10) with two center gears (7) (12) and two satellite gears (9) (20) symmetric arrangement be assemblied in the housing of forming by left and right half housing.Left and right sides gear (14) (19), denture clutch (15) is assemblied on the left and right gear wheel shaft (16) (18) the same axis of compression spring (17), forms differential locking-device.
When half housing of the right side of pair variable gear (1) transmission diff,, export by center gear (7) (12) through satellite gear (9) (20), again through gear (6) (13), left and right gear (14) (19), left and right gear wheel shaft (16) (18), two front-wheels of transmission.When the front-wheel turning was subjected to resistance different, the diff output speed was poor, so that tractor steering.When a front-wheel skidded, diff also output speed was poor, and trac. just can not advance.For eliminating this phenomenon, the denture clutch that closes (15) makes left and right gear wheel shaft (16) (18) become as a whole, pinned diff, make the identical rotating speed of left and right gear (14) (19) output, drive front-wheel by force, increase the trac. skid resistance.
Claims (3)
1, the bearing circle differential steering device of workers and peasants' 12 type trac.s is made up of bearing circle mechanism and box of tricks, it is characterized in that box of tricks is to be made of cone gear differential mechanism and differential locking-device.
2, bearing circle differential steering device according to claim 1, it is characterized in that described diff by steering shaft (5) and planet wheel spindle (10) with two center gears (7) (12) and two satellite gears (9) (20) symmetric arrangement be assemblied in by about in the housing formed of half housing (8) (11), planet wheel spindle (10) is vertical with steering shaft (5) and pass steering shaft (10), and right half outside is made gear forms and is meshed with a pair variable gear.
3, bearing circle differential steering device according to claim 1 and 2, it is characterized in that described differential locking-device is by left and right sides gear (14) (19), left and right tooth wheel shaft (16) (18), denture clutch (15), compression spring (17) is formed, and they are contained on the same axis.
