Description

The utility model can be used in the field of automobile transport to increase the adhesion of the drive wheels to the supporting surface in slippery conditions.

The problem of ensuring the safety of road transport on roads in conditions of limited adhesion of wheels to a supporting surface, in particular when driving in icy conditions, is solved by various means. Usually, studded rubber is used for these purposes, cars are equipped with self-locking differentials, anti-lock and anti-slip systems of various designs. The aforementioned methods of combating the sliding of car wheels are of relatively high cost and are mainly used in passenger cars.

The closest in technical essence and the achieved effect is a device for feeding sand to the wheels of a railway vehicle, disclosed in the copyright certificate (SU 366106 A L.I. Matveev, 03.03.73, B 61 C 15/10). The specified device includes a hopper for storing abrasive material and means for supplying abrasive material to the area of contact of the wheel with the supporting surface, which is an atomizer with an ejection nozzle.

The disadvantage of the prototype is that it is not oriented to use in road wheeled vehicles, does not provide the required level of efficiency in connection with the use of sand as an abrasive material and is not sufficiently reliable due to possible clogging of the ejection nozzle when the vehicle is moving along the road in normal mode.

The objective of this utility model is to improve the patency of mobile wheeled vehicles in slippery conditions by increasing the efficiency and reliability of the means for spreading bulk (abrasive) materials.

This goal is achieved by using the air coming from the receiver through the exhaust pipes when opening the taps with the help of solenoids, for scattering bulk material under the drive wheels of the vehicle. The device allows to use not only sand, but also fine gravel, slag, etc. as bulk material. This is achieved by the fact that the bottom of the hopper has windows of various sizes with an adjustment column. In addition, the presence of a helical agitator located inside the hopper prevents compaction or adhesion of the bulk material.

Currently, devices for spreading bulk materials under the drive wheels of mobile cars using air coming from the receiver are unknown, which proves the compliance of the proposed device with the criterion of "novelty."

The device for supplying bulk materials under the drive wheels of mobile machines includes (Fig. 1 - General view of the device for supplying bulk materials under the drive wheels of mobile machines, Figure 2 - Schematic diagram of the device for feeding bulk materials under the drive wheels of mobile machines (view of the hopper side), Fig. 3 - Diagram of the brake chamber with agitator) hopper 4 for storing bulk material 2, in the bottom of which there are windows 16 with an adjustment column 18; guide chute (diffuser) 3; a pipe 5 with a valve 10 and a solenoid 11, which exhausts air from the receiver 8; a hose 6 supplying air from the receiver 8 to the brake chamber 12 having a rod 20, a rack 24 and a gear 22 rotating the agitator 19 located inside the hopper; angular acceleration comparator 14 with an inductive sensor 15 mounted on the drive wheel 1.

A device is installed for each drive wheel.

The device operates as follows. When the wheel hits a slippery stretch of track, it begins to slip. In this case, the angular acceleration of the stalled wheel increases. If the angular acceleration of the stalled wheel is 10 ... 25 s ^-2 and higher, then the angular acceleration comparator 14 is turned on. When it is turned on, the valve 10 located on one of the outlet pipes 5 is opened using the solenoid 11 and provides air from the receiver 8 to the hopper 4. A portion of bulk material 2, fed into the hopper 3 of the hopper through the window 16 of the adjustment column 18, is discharged under the influence of air under the drive wheels 1 of the machine. When the angular acceleration of the skidding wheel decreases and the skidding stops, the angular acceleration comparator of the drive wheels is turned off, the air supply to the hopper is stopped. To avoid compaction or adhesion of particles of bulk material, the design provides for the simultaneous supply of air from the receiver 8 to the brake chamber 12, which drives a screw-type agitator 19 located inside the hopper.

In the case of joint slipping of the drive wheels, the automatic device control system (angular acceleration comparator) does not work. Simultaneous air supply from the receiver to the left and right exhaust pipe can be provided by pressing a button in the operator's cab.

The inventive device for feeding bulk materials under the drive wheels of mobile cars is of interest to the national economy, as it allows to increase the patency of these machines in slippery conditions.
