Abstract
The present invention is directed to an axle coupling device that enables a vehicle to rotate in place or with a short radius, specifically a first bevel gear connected to the axle of the gear assembly side; A second bevel gear connected to or separated from the first bevel gear while moving from the driving wheel side axle to the left or right by a predetermined distance; And a third bevel gear axially installed between the first and second bevel gears to be engaged with each other to drive the driving wheels on both sides of the vehicle in opposite directions. It will provide an axle connecting device to rotate.
Description
The present invention relates to an axle linkage that allows the vehicle to rotate in place or with a short radius.
In general, a vehicle includes a transmission, a drive shaft, a gear assembly, and an axle for transmitting engine power to a drive wheel. The engine generates power by burning fuel, the transmission adjusts the rotational speed and torque of the power, the drive shaft transmits the power to the gear assembly, and the gear assembly drives the power to both drive wheels through the axle. To pass.
Conventional driving wheels are connected to each side to drive in the same direction through one axle, so that a large radius of rotation is required to rotate the vehicle 180 degrees in proportion to the length of the vehicle body.
On the other hand, the vehicle can be easily operated in a narrow space as the rotation radius is reduced, in particular, in the case of agricultural special vehicles or industrial special vehicles, the smaller the radius of rotation can work efficiently in a narrow space.
However, in the case of such a special vehicle, both driving wheels not only drive in the same direction, but are usually configured to transmit power to the rear wheels, and since the steering device is connected to the front wheels, it is difficult to reduce the turning radius.
In addition, the conventional vehicle has a problem that takes a lot of overload when switching direction.
The present invention is to solve the conventional problem that it is difficult to reduce the radius of rotation of the vehicle in a structure in which both driving wheels of the vehicle rotate in the same direction.
The axle connecting device of the present invention is installed on the axle connecting the gear assembly and the drive wheels for transmitting power of the engine, the first bevel gear connected to the axle of the gear assembly side; A second bevel gear connected to the driving wheel-side axle while being installed to face the first bevel gear, the second bevel gear being configured to connect or disconnect power on the coaxial shaft with the first bevel gear through a left and right movement; And a third bevel gear, which is installed between the first and second bevel gears and is engaged with the first and second bevel gears, wherein the second bevel gears are engaged or separated from each other according to left and right movement. It is configured by.
The connecting means for connecting or separating the first and second bevel gears coaxially includes a engaging protrusion protruding from an end of the first bevel gear; And a coupling groove protruding from an end of the second bevel gear and engaged with the coupling protrusion while being inserted.
The second bevel gear is key-coupled to move left and right from the driving wheel side axle by a predetermined distance, is coupled to an outer surface of the central axis of the second bevel gear, and moving means for moving the second bevel gear left and right; It is configured to include.
The moving means includes an annular engaging groove formed along the outer surface of the central axis of the second bevel gear; And a lever formed to fit on both sides of the locking groove.
And a housing for covering the first bevel gear to the third bevel gear and for axially coupling the third bevel gear.
According to the axle connecting device of the present invention, by allowing the driving wheels on both sides of the vehicle to be driven in opposite directions, not only the effect that the vehicle can turn in place (spin turn) or realize a short radius of rotation, but also for agriculture In addition, there is an effect that can further improve the work efficiency of industrial special vehicles.
According to the axle connecting device of the present invention by forming a simple and stable structure for changing the driving direction of the drive wheels of both sides, there is an effect that can reduce the installation and production costs in applying to the vehicle.
