The author planned his all-terrain vehicle, like an all-terrain vehicle of a turning design with all-wheel drive, which should be comfortable for long trips for fishing or hunting. The all-terrain vehicle holds up to two people, as well as about two hundred kilograms of cargo. Before construction began, the author made a large number of calculations, as well as made diagrams of the basic structures of the all-terrain vehicle.
To create this all-terrain vehicle, the author required the following materials:
1) Bridges from gas-44
2) wheels vi-3
3) Engine 20 hp
4) Snowmobile CVT
5) Gearbox from Peugeot 206
6) junction box from the car Niva.
7) profile pipe
Consider in more detail the stages of construction of this all-terrain vehicle.
To begin with, the author sketched out several designs of the all-terrain vehicle.
The all-terrain vehicle frame is planned according to this scheme and will be created from a profile pipe measuring 40 by 20 by 2 and 20 by 20 by 2.
The frame of the cabin and kung is planned to be made of exactly the same pipe:
The leading safari variator will be adapted for the Chinese all-terrain engine. The driven variator will be made to order on the shaft and two housing bearings.
At the ends of this shaft will be located flanges from the cornfield. One of them will be directed forward for the future placement of the winch. The clutch disc will be screwed onto the second flange through a spacer, and the spline part of the disc will be seated on the input shaft of the gearbox.
The clutch disc is also good in that it has shock absorbers that will smooth out the shock of the transmission. The complexity of such a scheme is to center the shafts of the gearbox and the variator.
The author considers it necessary to install a lock, as an option, a limited-slip differential in the gearbox. Although blocking is not often used, sometimes it is needed.
Doubts in the scheme prevailed only about the junction box.
For verification, the author calculated the gear ratios with and without a transfer case.
Option with mounted transfer case:
without her:
As you can see, the variator starts working after two thousand revolutions, so the option of installing the transfer case looks better, since the minimum speed of the all-terrain vehicle at 1 kilometer per hour makes it easier to overcome deep snow, logs, ruts.
Perhaps it is planned to replace the safari variator with a variator of carais for four-stroke engines of 3600 rpm.
Regarding the transfer case: with it, the total weight together with the engine and the variator will be higher, and the engine power installed with it will be lower, on the other hand, the author does not need a powerful engine for his needs. Therefore, several more options were considered.
One of them was the installation of a 20 liter engine. from. with a variator and a transfer case, by weight and power output, such a design will be average. The author does not want to abandon the transfer case because the differential in it can absorb transmission shocks, which will positively affect the machine’s life.
But the author also considered the design without a transfer case. From the variator, it goes directly to the gearbox from the front drive. A similar scheme just requires an engine of 20 hp. and the presence of self-locking in the gearbox.
For clarity, the author even made a table with the pros and cons of both schemes:
Meanwhile, the vi-3 lightweight wheels were purchased.
And also work began on the assembly of the main components of the all-terrain vehicle.
A fist from gas-66 was prepared, which is planned for installation on the future frame of the all-terrain vehicle, but the author was confused by the heavy weight of the structure:
After the author had wheels for an all-terrain vehicle, he began to prepare bridges from gas-44 for installation on an all-terrain vehicle:
Then the author proceeded to create an all-terrain vehicle frame:
Initially, the author planned to make a fracture node according to the Uvat scheme, but since the bridges were heavier than expected, a heavier Trom8 node was made for greater reliability.
Below is a drawing where you can see the height of the half-rovers of an all-terrain vehicle:
The turning work on the parts for the fracture site was completed:
After which the knot was made to break the frames of the all-terrain vehicle:
The next step, the author decided to brew the differential in the gearbox:
And also I got a backstage specially for my gearbox:
The driven variator still decided to install Buranovsky, made on a makeshift shaft from CT45:
an engine was also installed. gearbox itself, transfer case and CVT. Installed steering and seat. The engine was mounted on a Buranovo subframe, which is located on rubber cushions.
The wings were reinforced:
Then a silencer was installed:
A scooter brake was used for the front axle of an all-terrain vehicle:
Throttle and brake pedals connected:
The variator for installing a disc brake was removed:
And here is the rear driveshaft with outboard bearing:
The steering draft has been changed to a straight line, for greater reliability:
