Technical field
The utility model relates to a kind of four-wheel drive hand tractor synchronizing device, especially one kind to be located at four-wheel drive hand
Help the synchronizing device in gear box of tractor.
Background technique
Currently, the widely used hand tractor in rural area is front-wheel drive, the power of engine through clutch, gearbox and
Steering cluth drives two front-drives, and vehicle is driven to move forward or back.Its trailer wheel be driven wheel, not with driving device
Connection.Since hand tractor center of gravity is preceding, after being supported on, front self weight is small, cause front-wheel to the adhesive force on ground relatively not
Foot, is difficult to generate enough tractive force.Along with rural area road conditions are most of bad, it is more that there are ramps, and road surface is soft, uneven
Or muddy phenomenon, front-wheel often skids when vehicle operation, causes vehicle to be unable to normal walking, the power of engine is unable to fully send out
It waves, and makes front-wheel serious wear, fuel consumption increases, and affects the production efficiency and economic benefit of user.In order to solve hand steered drag
This is insufficient for machine drawing, and people have carried out technological improvement to hand tractor, do not influenced to be transmitted to front-wheel by the power of gearbox
In the case of, then by devices driving-trailer vehicle wheel rotations such as universal shaft, transmission case, trailer rear axles, it is hand steered to develop four-wheel drive
Tractor.But most of improved four-wheel drive hand tractors are due to structure, design etc., when walking, often goes out
Existing forward and backward wheel operates asynchronous problem, clamping stagnation, idle running phenomenon occurs, causes unstable working condition, or even manipulation difficulty,
Increase security risk when operation.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides one kind and is located at four-wheel drive speed changing box for walking tractor
Interior synchronizing device, it is not only structurally reasonable, and when operation, forward and backward wheel operating synchronized, and tractive force is big, manipulation it is flexible,
Stability is good, high safety.
The technical scheme adopted by the utility model to solve the technical problem is as follows: by gear box casing, the 4th transmission shaft, passing
The synchronous dress of the compositions such as moving gear, the 8th transmission shaft, rear power output shaft being located in four-wheel drive speed changing box for walking tractor
It sets, is increased appropriate on the downside of the rear portion of its gear box casing, add the VIIIth hole and a use that one is used to install the 8th transmission shaft
In the axis hole of installation rear power output shaft, the 8th transmission shaft is splined shaft, is equipped in the left end of the 8th transmission shaft with fork slot
Balladeur train is equipped with driving bevel gear in the right end of the 8th transmission shaft, driving bevel gear and is mounted on quilt on rear power output shaft
Dynamic bevel gear is meshed, and a transmission gear is added on the left of the central driver gear on the 4th transmission shaft, and balladeur train exists
Be meshed under the stirring of shift fork with transmission gear, passive bevel gear by rear power output shaft and the first universal shaft, drive afterwards from
Clutch and the second universal shaft rotate with rear axle and connect.
A kind of synchronizing device being located in four-wheel drive speed changing box for walking tractor, the number of teeth of transmission gear are
The number of teeth of 18 teeth, balladeur train is 24 teeth, and the number of teeth of active and passive bevel gear is identical, is 25 teeth.
The utility model has the beneficial effects that adding the 8th transmission shaft and rear-guard power output shaft in gearbox, the 4th
Transmission gear is added on transmission shaft, and rear-guard clutch is set between the first universal shaft and the second universal shaft, and it is hand steered dilatory to make
Machine becomes front and back four-wheel drive from front two-wheel drive.Turned simultaneously according to the revolution, preceding wheel diameter and rear drive shaft of drive axle
The pertinency factors such as the ratio of several, rear wheel diameter, the scientific tooth for calculating transmission gear, balladeur train and active and passive bevel gear
Number, front-wheel when this four-wheel drive hand tractor being made to walk reach synchronous with trailer wheel, improve its driving power and in mud
The handling capacity on muddy, hollow and slope road reduces fuel consumption and tire wear, runs smoothly, securely and reliably.
