RU2740952C1 - Safe wheel for vehicles with increased load - Google Patents

Abstract

FIELD: transportation.SUBSTANCE: wheel is mainly intended for large-capacity wheeled vehicles experiencing high load on wheels (aircraft, trucks or special equipment), which, as a rule, use inflatable or solid tires. Wheel comprises wheel disc and tire with tread. Also there are two strong safety discs, between which the rubber reinforced with metal safety ring is located. Each of the three working elements comprises a tread on their outer surface, and the difference in the diameters of the safety discs and the ring does not exceed the dimension of elastic deformation of the safety discs.EFFECT: technical result is increase in wheel safety and reliability.1 cl, 1 dwg

Description

The invention relates to mechanical engineering, namely to airplanes and automobiles (trucks, as well as special heavy equipment, which is experiencing heavy loads on the wheels). Reliable wheels are very important both for aircraft and for various transport equipment, since they are the main criterion for the safe transportation of bulky and heavy loads and people.

The following patents are known related to this topic. Patent No. 2055746 "Wheels with grousers", publ. 03/10/1996. There are special hooks on the wheels (on the end surfaces of the rims) when transporting vehicles on bad roads and over rough terrain. Patent No. 2529574 "Pneumatic tire variants" has different grooves on the tread with spikes. Publ. September 27, 2014.

Patent No. 2523539 "Pneumatic tire", which is designed for driving on snow, and the tread has a pair of longitudinal grooves. Publ. 07/20/2014. Patent No. 2515621 "Pneumatic Tire Tread" with grooves for water drainage and noise reduction. Publ. 05/20/2014.

Patent No. 2483936 "Automotive tire with elastic spokes", publ. 10.06.2013. The automobile tire is made with elastic spokes made of elastic polyurethane, connecting the outer ring with a tread, variable in thickness from the inner side, and the inner ring, fixed on the metal rim of the wheel.

It is also known a car wheel containing two or more bearing discs, combined into a frame cylindrical structure with several sealed sections, on the outside of which pneumatic tires of different designs are mounted for the required purpose, while the shape of the working surface of the wheel as a whole and each pneumatic tire is individually regulated by pressure air stored in the sealed sections of the wheel (see RF Patent No. 230155, IPC В60В 11/06, 15/18, 17/02).

Car wheel. IN AND. Stolbov et al. RF Patent. No. 2005133567; publ. 20.06.2007, - bul. No. 17, taken as a prototype.

A frame structure carrier disc with pneumatic tires is provided here. However, this technical solution is not able to keep the vehicle on the road if the tires are damaged, and therefore does not guarantee the safety of the vehicle.

The purpose of the invention is to create a wheel of a vehicle, for example, an aircraft, usually a truck and other wheeled vehicles, experiencing heavy loads on the wheels, which maximally guarantees trouble-free movement on the highway with the possibility of a timely stop of movement, as well as the possible resumption or continuation of movement at a certain speed ...

The technical solution is achieved by making a wheel with two safety discs made of the most durable material, between which, under a common rubber tire, an additional safety ring made of cast rubber material with metal reinforcement is located inside. The diameter of the safety ring is smaller than that of the safety discs by the amount of elastic deformation of the disc material, so that all three elements simultaneously perceive the load from the mass of the vehicle and the transported cargo. Each of the three elements located under the common tire (discs and ring) have a protector that reduces unwanted wheel slip.

The essence of the invention is illustrated by the figure, which shows: 1 - wheel disk; 2 - a tire with a protector; 3 - two symmetrically located laterally in relation to position 4 of the safety disc; 4 - safety molded rubber ring, reinforced inside with metal.

The result of this technical solution is a new, robust safety wheel design for heavy-duty vehicles.

In the manufacture of a wheel, composite strong safety discs are put on the wheel rim, which are fixed using glue or intermediate spacers for their vertical parallel arrangement with each other. Then, a non-metallic safety ring is poured into the space between these two safety discs using removable molds for this manufacture. After hardening / vulcanization and removal of the molds, a common tire with a specific tread shape is formed and placed on all three elements (two safety discs and a middle safety ring). During operation, the middle safety ring and two safety discs perceive the load acting on them both from the weight of the vehicle and from the unevenness of the road surface. The presence of built-in disks and a safety ring reserves the overall reliability of the wheel in the event of a puncture or partial destruction from time to time (due to aging or due to a technological defect missed during manufacturing). In this case, in the event of a complete destruction of the tire, the movement of a heavy vehicle until it stops completely is possible on durable safety discs and a safety ring, the outer surfaces of which have a protector that prevents the wheel from sliding smoothly, eliminating the occurrence of an emergency. In addition, at a lower speed, there is a real opportunity to continue moving the vehicle if necessary.
