Antiskid device

 

(57) Abstract:

Use: for mounting on wheel when driving on icy and snowy road in winter, on a dirt road in the spring thaw, summer and autumn rains. The essence of the invention is that the push hub is made with pressure ring with the alignment elements, through which are passed the levers with the possibility of radial displacement. 3 Il.

The present invention relates to wheels of vehicles, and in particular to devices for increasing the traction of the wheels and the road surface, and can be used for installation on car wheels with pneumatic tyres with the aim of driving on icy and snowy road in winter, and grusovoi the road during the spring thaw, summer and autumn rains.

A device for increasing the strength of adhesion of the wheels with the surface of the roller (patent USSR N 1186078). The device comprises a circular disk mounted on the wheel rim. It is made in the form of rigidly connected with each other shelves, which are oriented in mutually perpendicular planes. One of the shelves adjacent to the side surface of the tire, is smarter beeny lugs. Bringing the blade of the snow into position and fixing the annular disk on the wheel rim is with another disk that is mounted coaxially with the wheel for rotation relative to it.

The disadvantages of this invention are, first, the complexity of the design, and secondly, the need to install it on the wheel rim. This complicates the manufacturing technology, increases the cost of the device and reduces usability.

It is also known antiskid device according to the patent of the USSR N 1590033, which includes a hub mounted on the drive wheels of the vehicle. On the hub by a retaining ring fixed bearing disk that contains the traction control levers with lugs. The opposite bearing established a transitional disk drive associated with the hub by means of a screw connection. Transitional disk is elongated in the radial direction of the hole and the transition element in the form of a collet connection.

The main disadvantage of this antiskid device, which is taken as a prototype, lies in the complexity of its design. This deficiency is accompanied by the complexity of manufacturing, high is the Oles, that also causes inconvenience in use.

It is also known antiskid device containing a mounted on the carrier hub levers, the free ends of which are made with lugs and curved to cover the tread-wheel, and a device for pressing levers to the protector in the form of a push hub mounted coaxially with the bearing hub and connected with it by means of the clamping bolt (U.S. patent N 4278122).

The disadvantage of this device is the design complexity.

To eliminate these disadvantages push hub is made with pressure ring with the alignment elements, through which are passed the levers with the possibility of radial displacement.

In Fig. 1 shows a traction control device, the radial cross-section; Fig. 2 - this is the same view from the side of the wheel; Fig. 3 is a General view of the antiskid device.

Antiskid device consists of a bearing of the hub 1, which sets out the traction control levers 2, the free ends of which are bent to cover the tread of the wheel tire 3 and provided with a lug 4. The amount of traction control levers is determined by the condition of the roadway, an opportunity to take stock of narutonaruto the ends they are threaded and fixed to the hub 1 by means of screws 5. The levers are made of springy elastic material, for example spring steel, synthetic materials.

Traction control levers 2 in rectilinear his part recorded with the lugs 6 in the compression ring 7. This is one of the variants of the fixing levers in the compression ring. Other options may be, for example, a hole or a groove, if the ring has a sufficient height, or the presence on the ring holder with a groove for the lever. The control ring 7 through the radial rack 8 is rigidly connected with the hub 9, which is located in a different plane than the control ring. The distance between these planes should be less than the stroke of the clamping bolt 10, which is passed through a Central hole in the push the hub 9 and threaded into the bearing hub 1. The same length of the clamping bolt 10 and the threaded part is determined based on a reliable fastening of the traction control levers on the bus wheels. To ensure reliable fastening of the traction control levers on the bus the wheels of the ratio of their shoulders from the bearing hub to the pressure ring and pressure ring to the free end of the lug is in the range from 3:2 to 2:1.

Securing traction control device on the bus wheels.

Removing the traction device tire wheel.

When loosening the clamping bolt 10 from the bearing hub 1 last performs translational motion from a push hub to the wheel. As a result, the pressure of the pressure ring 7 on the traction control levers 2 is removed. The free ends of the levers 2, 4 lug away from the surface of the tire 3, which allows you to remove the antiskid device with wheels.

Technical appraisal and economic benefits PIM:

the simple design of the device (suffice it to say that it consists of 7-8 dissimilar elements, this simplifies the manufacturing technology of the device and reduces its cost and creates ease of use);

the possibility of samosokhraneniya on the bus the wheels without the use of his work items (disk, rim, hub), it also contributes to the improvement of operating conditions.

ANTISKID DEVICE containing a mounted on the carrier hub levers, the free ends of which are made with gruntsudenu and bent to cover the tread-wheel, and a device for pressing levers to the protector in the form of a push hub mounted coaxially with the bearing hub and connected with it by means of the clamping bolt, characterized in that the push hub is made with pressure ring with the alignment elements, through which are passed the levers with the possibility of radial displacement.
