Description

The invention relates to the field of engineering, in particular to inertial units (engines) - devices mounted on wheeled tractors with rear-wheel drive power take-off, accumulating mechanical energy of rotation and movement of goods, in order to overcome short-term loads on the engine and transmission, increase their operational durability reducing overall fuel consumption.

A device is known - an inertial installation consisting of a bed, a drive shaft, driven shafts, gears, rollers, spurious gears, flywheels, detachable couplings, jacks, eccentrics, spools, forks, pump station. (USSR Patent No. 207436 IPC G01m).

The disadvantage of this device is the significant complexity of the installation, a large number of involved components and parts, energy consumption, inconvenience during operation.

A device is known - an inertial engine, consisting of a vacuum casing, a flywheel, an output shaft, a clutch, an engagement mechanism, an air pump (USSR Patent No. 565113 IPC F03G 3/08, taken as a prototype).

The disadvantage of this device is the large number of nodes involved, the need to maintain a vacuum in the casing of the installation, the high complexity and energy intensity of the structure.

An object of the invention is to overcome short-term loads on the engine and transmission of the tractor, increase their operational durability, reduce overall fuel consumption by installing a flywheel-type control device with a variable moment of inertia, the simplicity of its design and manufacture, reducing the number of involved components and parts in comparison with prototype, high reliability, ease of installation, maintenance and operation.

The technical solution to the problem is to create a flywheel-type device-regulator of a wheel tractor mounted on the splines of the rear power take-off drive of a wheel tractor with a variable moment of inertia, which includes a system of moving unbalanced loads and return coil springs.

The task is achieved in that the device is made in the form of a mechanism mounted on the splines of the rear power take-off drive of the wheel tractor, consisting of a flat flywheel disk with guides on which movable unbalanced loads and return coil springs are installed.

Figure 1 shows a device - a flywheel type controller with a variable moment of inertia (profile view), figure 2 shows a side section of a device - a flywheel type controller with a variable moment of inertia,

The device comprises a flat disk-flywheel 1 with a central mounting hole 2 and guides 3, on which the movable unbalanced loads 4 are adopted, preloaded by the return coil springs 5.

The device operates as follows:

When the engine is idling or not connected to the power take-off shaft, unbalanced loads 4 are in a position close to the center of the flat flywheel disk 1. In motion, with increasing speed or power input from the tractor engine, under the action of centrifugal acceleration, unbalanced loads 4 produce rotation around the axis of attachment and movement along the guides 3, compressing the return coil springs 5 and accumulating kinetic energy. With an increase in short-term overloads, slippage, and interruptions in the stable operation of the engine and transmission, the power take-off shaft slows down, as a result of which, under the influence of return coil springs 5, the unbalanced weights 4 reverse and release the energy accumulated by them, which performs the work of forcing the power take-off shaft tractor, reducing overload and leveling the power balance of the tractor. At the same time, the volume of the fuel mixture supplied by the high-pressure fuel pump of the tractor also decreases, which leads to savings in fuel and lubricants.

The use of this invention, which has high reliability, low cost, ease of maintenance and operation, with a fairly simple design and ease of manufacture of a flywheel type governor with a variable moment of inertia will increase the operational life of the engine and transmission of the tractor, reduce overall fuel consumption and improve transport performance when using .
