LV10410B - Emergency breaking device for vehicles - Google Patents

Abstract

This invention pertains to transport vehicles, namely emergency brake devices attached to the bearing structure consisting of drive, casing, dynamic element, and a unit for fixing the transport vehicle on the road surface. It is suggested to arrange the emergency brake device (fig.1) in such a way that the drive with the use of pushing rod activates the dynamic unit in the form of a detonator with a primer charge, and then created in it pneumatic shock wave releases a harpoon anchor in the shape of a truncated triangle with a sharp tip and a certain side slope angle to ensure that the harpoon anchor is fixed on the road surface. Furthermore it is suggested to wind an elastic cable or reinforced belt around the axis of a freely rotating reel fixed inside the casing of the device to connect the harpoon anchor with the transport vehicle to slow down its speed and absorb the pneumatic shock wave inertia force.<IMAGE>

Description

EMERGENCY BRAKING DEVICE FOR VEHICLES

The invention relates to the construction of vehicles,

5 · Especially on emergency braking systems.

In difficult road and meteorological conditions, situations may arise in which emergency braking systems incorporated in the vehicle may fail in emergency situations. Therefore, increasing traffic safety

10. to this end, develop various technical solutions for stand-alone emergency braking systems.

There is a known method of stopping a machine rapidly with a special braking component which is kinematically linked to the load-bearing part of the vehicle. Braking

15 · In time, this element is located between the wheel and the road surface. The road facing surface of such an element is made of a material with a very high adhesion to the road surface. The wheel-facing surface is covered with a slip-resistant grease, which is protected by an easily breakable waterproof film20. you / 1 /.

Another solution to this problem is found in the construction of a relatively sophisticated emergency braking device. This device presses a special plate on the road surface during emergency braking, creating a thinning between the plate and the road surfaces.

25 · Thinning is achieved by a centrifugal pre-vacuum pump built into the unit, the rotor of which is designed as an energy-accumulating power wheel. The free volume of the centrifugal pump is directly connected to the free volume of the auxiliary pump and the flexible tube in turn connects them to the free space of the plate. The braking plate is attached to the load-bearing structure of the vehicle by means of movable pivot bearings. Air extraction

5 · The system is closed by self-sealing dampers operated by pneumatic actuator / 2 /.

However, the above technical solutions do not always ensure that the vehicle is kept on the road in an emergency; on the edge of the cliff, bumpy and rumbling

10. on a road where a sufficiently deep depression between the stop plate and the road surface cannot be formed.

The present invention provides a new technical solution for an emergency braking device that locks a vehicle in an emergency 15 based on another operating principle. li anchoring it on the road. For anchoring securely to the road surface, the anchor is in the form of a feathered harpoon formed by a bevelled triangle with a pointed tip and a specially selected slope angle.

The emergency brake is actuated by actuator / 10,

20 / which is located in the vehicle control area so that it is within easy reach of both its driver and other occupants and is not accidentally confused with other controls. The actuator (10) is actuated by piercing the cartridge (9) with the pusher bar (6). a bin detonator (5). The shock wave of the shot releases the shutter (7), which secures the anchor-harpoon (3) at rest. The harpoon anchor strikes the road surface but remains attached to the braking device by means of a cable or an elastic reinforced ribbon (8) which is wound in a resting position on a reel (4) which can

30. rotate freely about an axis (II) mounted in the housing (2) and its housing.

The emergency braking device shall be firmly attached to the vehicle's supporting structures.

Emergency braking devices for a variety of vehicle types, power, and eccentricity characteristics, varying in mounting location, impact strength of capsule charge, rope or elastic strapLV 10410

but satisfies the described constructive solution.

Anchor-harpoon's ability to hit the road surface causes a sudden braking effect, with a braking force

5. mainly determined by the impact wave power of the projectile charge, but inertia is canceled by the rope or elastic band.

The emergency braking device provides additional driving safety features, increases the likelihood of stopping the vehicle in the event of a dangerous trip down 10. Braking systems encountered. This results in additional psychological comfort for the riders, as the degree of dependence on sudden vehicle damage is reduced.

Providing dangerous goods transport with such devices reduces the risk of environmental pollution.

The autonomous emergency braking device of the invention is shown in the drawing. It consists of a housing (2) enclosed by a housing (1) and containing its structural elements: an anchor-harpoon (3), which is held in position by a lock (7). Rope on reel (4) or flexible, reinforced20. this tape (8) links the anchor-harpoon to the body of the braking device and its casing through the fixed spindle axis (11). A charge capsule is placed on the housing cover directly in connection with the actuator (10), but a detonator (5) and a shock-absorbing rod (6) located directly below the cover, which can act directly and functionally on the shutter (7) the product has a special construction element (12).
