SK16502002A3 - Controlling device of anti-skid construction in non-inflatable tyre with hydraulic cylinder - Google Patents

Abstract

The hydraulic brake pump (1) manages the hydraulic cylinder (11). The swing bodies (21) with the return springs (212) and with the operating rods (213) which drive the anti-skid spikes (31) or coupled by the con-necting rod (32) are managed the hydraulic cylinder (11) by the connecting rod (211). All these members are placed into the internal space of the non-inflatable tyre and/or into the internal space of the rim.

Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a control device for a non-slip structure in a non-inflatable tire for wheeled vehicles and to the field of transport.

Current state

In order to prevent the wheels of the vehicles from slipping on an icy, wet road or a road covered with drivable snow, the patent literature describes anti-skid structures in U.S. Patents 5,398,742 and 4,119,132, Swiss Patent 617,624, or French Patent 232,776 whose control devices for anti-slip studs are installed and operated mechanically or hydraulically from the outside on the tire casing surface, or through the sidewall and through the tire tread.

The disadvantage of these structures is their mechanical vulnerability when driving in rough terrain, complexity and, in hydraulic systems, the risk of loss of tightness of the anti-skid device or tire.

The essence of the technical solution

These drawbacks are largely overcome by the anti-skid control device located in the interior of the inflatable tire of the invention.

SUMMARY OF THE INVENTION The control device for controlling the anti-skid structure consists of AB S and EDS systems, a hydraulic pump for controlling the anti-skid points, a hydraulic cylinder with a piston, a connecting rod located in the interior of the inflatable tire rim, partially rotatable bodies with return springs and control rods connected to non-slip spikes in transverse through holes in the tread pattern of a non-inflatable tire.

The advantages of the non-slip tire control device in the inflatable tire according to the invention are that the structure is poorly functional in function and can be activated from the driver's position or automatically by hydraulics connected to the ABS and EDS braking and anti-skid system. characteristics of road tires.

The anti-skid control device in the non-inflatable tire may be activated automatically or from the driver's seat. preferably deactivate at any speed or direction of rotation of the tire.

and

The advantage of the non-slip structure control device in the inflatable tire is that it is activated, functional and independent of the direction of rotation of the tire, both during rapid acceleration as well as intense braking or cornering.

Overview of images

The subject matter of the invention is illustrated in more detail in Figures 1 and 2, wherein FIG. no. 1 shows a longitudinal section through a non-slip tire control device in a non-inflatable tire, showing a hydraulic pump for controlling the slip bars, a hydraulic cylinder with a piston and a connecting rod connecting the pivoting bodies, control rods for rotating slip bars mounted on a self-supporting flexible structure housed in transverse parts of the non-inflatable tire tread.

Fig. no. 2 is a longitudinal cross-sectional view of a non-slip tire control device in a non-inflatable tire, showing the device after actuation in forward operation.

Example

An anti-skid control device in a non-inflatable tire reinforced with a self-supporting resilient structure, with transverse through holes located in the treads as well as rotating anti-skid points, equipped with a wheel rotation indicator device, control and evaluation computer unit of ABS and EDS systems. no. 1 and 2 comprises a control device for controlling the anti-slip structure by means of the hydraulic pump 1 of the hydraulic cylinder 11 with the piston H1, a connecting rod 211 disposed in the interior of the inflatable tire rim which is connected to the pivot bodies 21. they consist of a return spring 212 and control rods 213 preferably of steel or plastic cables and rotatable anti-slip prongs 31 mounted in the interior of the transverse through holes 311 on the self-supporting elastic structure 4 of the vulcanized portion of the inflatable tire tread 3.

The anti-skid control device in the non-inflatable tire is activated, partially activated or deactivated from the driver's position by a hydraulic system, alternatively automatically by means of sensors indicating a significant deterioration of the adhesion properties of the tires to the road surface according to deceleration. accelerating the wheel at any tire rotation speed, which activates the control and evaluation computer unit of the ABS and EDS hydraulic systems.

These control systems control the hydraulic pump 1 and subsequently the hydraulic cylinder 11 with the piston 111 which, by means of a connecting rod 211 located in the interior of the rim of the inflatable tire, controls the control rods 213 preferably made of steel or plastic cables.

The control rods 213 extend or extend. on the contrary, the rotatable non-slip tines 31 slide out of the inflatable tire through the inner free space of the transverse through holes 313 in the vulcanized tread 3 mounted on a self-supporting resilient structure 4.

This action is counteracted by the return springs 212 of the swivel bodies 21, which return the swivel bodies 21 to the initial position when the system is deactivated.

Industrial usability

The anti-skid control device according to the invention is suitable for all types of wheeled road, off-road and military vehicles advantageously utilizing ABS and EDS systems coupled with non-slip spikes in a non-inflatable tire when driving in severe off-road conditions or during winter.
