Description

The invention relates to road transport and is intended to increase the adhesion of wheels to slippery roads.

A device for preventing slipping of the driving wheels of mobile machines (RU, patent No. 2289514, IPC B60B 39/04, published on December 20, 2006) and a device for improving the coupling and braking properties of slipping wheels on slippery bearing surfaces [2, 3], including a hopper for storing bulk (abrasive) material with a pipe connected to it with a shutter connected to the solenoid, and a chute for guiding the bulk material under the drive wheels.

These devices are difficult to manufacture and unreliable in operation.

Various variants of devices for preventing slipping of the drive wheels of a vehicle are also known, including drives (bins) for storing abrasive material installed in front of the drive wheels of the vehicle, and means (guiding channels) for feeding it directly onto the tread surface of the wheel or under the wheels of the vehicle [4-8].

The disadvantages of all of the above devices is the difficulty of placing containers with abrasive material directly in front of the drive wheel; caking of the material and the impossibility of feeding it at the right time under the wheel, as well as the difficulty of dispensing its portions.

The closest technical solution to the claimed is a device to prevent slipping of the drive wheels of the vehicle [9], including a hopper for storing bulk material, a means for feeding it under the drive wheels, which is a hub (impeller) mounted on the drive wheels of the vehicle angular accelerations with an amplifier and inductive sensors. The bottom of the hopper is equipped with windows with an adjustment column. In addition, the hopper is equipped with a tedder and a conical guide groove for feeding bulk material under the drive wheels.

This device allows you to automate the process of feeding bulk (abrasive) material under the driving wheels of the vehicle, however, automation of the process of feeding the abrasive can not be a super task, since the driver does not have any difficulty or difficulty to press the button at the right time. In addition, the loss of adhesion of the drive wheels to a slippery road will cause the vehicle to skid and stop, and when the abrasive material is automatically turned on, it will be too late to pour it onto the road in front of a stationary vehicle. The movement of bulk abrasive material in horizontal sections requires a large expenditure of energy and at low temperatures it sometimes becomes impossible at all because of freezing into a monolith of material that has accumulated moisture from the air. A large consumption of abrasive material is also required.

The objective of the invention is to improve the design of the device.

The technical result that will be obtained from the use of this invention is to increase the adhesion of the drive wheels with slippery roads and reduce the consumption of abrasive material.

The technical result is achieved by the fact that in the device for preventing slipping of the drive wheels of the vehicle, including a container for storing abrasive material, a means for feeding it and a guide chute, a container for storing abrasive material is made in the form of vertical pipes installed behind the vehicle’s cabin, means for Material feed is made in the form of horizontally inclined pipes, at the beginning of which feed conveyors are installed, and a crusher is installed in the guide chutes. The lower end of the crusher can be installed in front of the drive wheels, or the lower end of the crusher enters the hole in the wing above the drive wheels, and part of the horizontally inclined pipe is made flexible. Spheres with a diameter of 10-150 mm are used as abrasive material to prevent slipping of the drive wheels of the vehicle.

The essence of the invention lies in the structural embodiment of the device and in the use as abrasive material of the spheres.

The implementation of the capacity for storing abrasive material in the form of vertical pipes installed behind the cab of the vehicle, provides a continuous supply of spherical material (spheres) in the conveyors under the action of gravity.

The implementation of the means for supplying material in the form of horizontally inclined pipes, at the beginning of which feed conveyors are installed, and crushers are installed in the guide chutes, ensures guaranteed transportation of spheres along horizontally inclined pipes due to the lower rolling friction force compared to sliding friction force.

Installing the lower end of the crusher in front of the driving wheels, or placing the crusher directly on the wing above the driving wheels, combining the crusher outlet with the hole made in the wing, and the execution of a part of the horizontally inclined pipe flexible depends on the design of the vehicle, which can have a very dense arrangement of different aggregates of vehicles.

Thus, the totality of the listed features as a whole ensures a high-quality supply of abrasive material at the right time under the driving wheels of the vehicle, eliminating material loss.

The use of spheres with a diameter of 10-150 mm as an abrasive material to prevent slipping of the drive wheels of the vehicle allows to prevent caking or freezing of the abrasive material and place the container with abrasive material in a vehicle’s place convenient for mounting and loading spherical material and ensure that they are fed into the crushing zone: in vertical sections - due to gravity, and in horizontal - due to lower rolling friction, which is an order of magnitude lower than friction zheniya in the case of particulate abrasive material.

From an analysis of the scientific, technical and patent literature of the claimed combination of features, ensuring reliable grip of the wheels with a slippery road due to the accurate supply of abrasive material and reducing its consumption, we have not revealed that allows us to conclude that the claimed technical solution meets the criteria of "novelty" and "inventive level".

The invention is illustrated by drawings, where:

figure 1 shows a General view of the device with the installation of the crusher in front of the drive wheels;

figure 2 is the same in the wing of the vehicle.

The device comprises a pipe 1 for storing abrasive material, installed behind the cab 2 and connected to a horizontally inclined pipe 3, at the beginning of which a feed conveyor 4 is installed, and a crusher 6 in the guide chute 5 (see Fig. 1).

The horizontally inclined pipe 3 may have a portion of flexible material 7, and the crusher 6 may enter a hole in the wing 8 above the drive wheels 9 (see figure 2). The device consists of two identical devices, one on each side of the vehicle.

A device for preventing slipping of the driving wheels of the vehicle operates as follows.

The container for storing abrasive material in the form of a vertical pipe 1, installed behind the cab 2 of the vehicle, is pre-filled with spheres of abrasive material with a diameter of 10-150 mm, which, under the action of gravity, enter the input of a feeding, for example, screw conveyor 4, when turned on, it is spherical material 10, one at a time, enters the horizontally inclined pipe 3.

The spherical material (sphere) 10 has a diameter 5% smaller than the inner diameter of the pipe 1 and the horizontal inclined pipe 3. The spheres 10 from the horizontal inclined pipe 3 fall at the inlet of the crusher 6 installed in the guide chute 5, rigidly connected to the horizontal inclined pipe 3. The whole structure is rigidly fixed to the vehicle frame.

The conveyor 4 and the crusher 6 are electrically driven from the vehicle's on-board network and are switched on by the driver from the cab 2. For convenience of filling a horizontally inclined pipe 3, a backup drive switch of the conveyor 4 and the crusher 6 can be installed. The switch in the cab acts on both sides of the vehicle, and a backup switch located in the upper part of the pipe 2 on one side of the vehicle. The crusher 6 has a grinding speed of the spheres 10 equal to or greater than the feed conveyor 4 to prevent overflow of the horizontally inclined pipe 3, the groove 5 and premature grinding of the spheres in the conveyor 4. Thus, the milled pieces of abrasive material 10 are grinded by the crusher 6 when the device is turned on and fall on the road in front of the drive wheels of the vehicle on both its sides, which ensures contact of the wheel with the road without slipping (slipping). The device can be used when starting a vehicle from a place, on ascents, as well as descents for safe and effective braking.

In the absence of space for the location of the crusher 6 above / in front of the drive wheel and the free-fall of the ground abrasive material onto the road, the crusher 6 is rigidly connected to the wing 8 of the vehicle (figure 2), for which a hole is made in the wing 8 for the lower end of the crusher 6, and part of the portion of the horizontally inclined pipe 3 is made of flexible material 7. In this case, the crusher has the ability to move vertically relative to the vehicle frame on the roughness of the road with the wheel 9.

This invention compared with the prototype has the following advantages:

- The absence of freezing of loose abrasive material that has accumulated moisture from the air into a monolith.

- Guaranteed transportation of the abrasive in the form of spheres to the crusher and the subsequent guaranteed hit of the grinding abrasive sphere under the drive wheels of the vehicle.

- No need to use dampers for bulk solids.

- Guaranteed placement of the device on all types of vehicles and with any layout schemes applied to them.
