Abstract

FIELD: mobile machines.
SUBSTANCE: wheel includes a standard disc, as well as a tire and rim with standard profiles. The rims of the wheels and tires are tapered to match the camber.
EFFECT: increasing the stability of a mobile machine, reducing the level of thermal loading and increasing tire wear resistance when mobile machines operate at high speeds.

Description

На всех современных мобильных машинах плоскости ведущих колес располагаются по нормали к основанию дороги. Ведомые же управляемые колеса, как правило, имеют так называемый положительный развал, соответствующий некоторому наклону своих плоскостей к опорному основанию в пределах 2-30.On all modern mobile machines, the planes of the drive wheels are located normal to the base of the road. Driven driven wheels, as a rule, have a so-called positive camber, corresponding to a certain inclination of their planes to the support base within 2-3 0 .

В настоящее время на зарубежных автомобилях, например Мерседес-Бенс, спортивного назначения, с целью придания большей поперечной устойчивости мобильной машине начинает применяться установка колес с существенно большим, превышающим 100, отрицательным развалом, как это показано на фигуре 1.At present, on foreign cars, for example, Mercedes-Benz, for sports purposes, in order to give greater lateral stability to a mobile car, the installation of wheels with a significantly larger negative camber, exceeding 10 0 , is starting to be used, as shown in figure 1.

В этом случае неизбежно нарушение нормальной работы шины, вызывающей неравномерный износ беговой дорожки протектора и ее повышенную термонагруженность, но и отрицательно отражается на той же устойчивости, ради которой мероприятие применяется, что наглядно проиллюстрировано в том же источнике и показано на фигуре 2.In this case, a violation of the normal operation of the tire is inevitable, causing uneven wear of the tread track and its increased thermal load, but also negatively affects the same stability for which the measure is applied, which is clearly illustrated in the same source and shown in figure 2.

В целях устранения отрицательных последствий установки колес с большим, в данном случае, отрицательном развалом предлагается новая конструкция колеса с пневматической шиной, показанная на фигуре 3, отличающаяся от традиционно применяемых конструкции колес и шин тем, что обод колеса 1 и шина 2 имеют коническую форму, с углом образующей, соответствующей углу развала колес, в данном случае отрицательного значения. При этом сохраняется стандартные профиль обода и шины, обеспечивающие равномерный по ширине беговой дорожки протектор износ шин, устраняются отрицательные последствия, характерные для традиционных конструкций шин и колес, устанавливаемых с большим развалом, как имеет место на спортивных скоростных автомобилях.In order to eliminate the negative consequences of the installation of wheels with a large, in this case, negative camber, a new design of a wheel with a pneumatic tire is proposed, shown in figure 3, which differs from the traditionally used designs of wheels and tires in that the rim of the wheel 1 and tire 2 are tapered, with a generatrix angle corresponding to the camber angle, in this case a negative value. At the same time, the standard profile of the rim and tires is preserved, which ensures uniform tire wear across the width of the tread, eliminating the negative consequences characteristic of traditional designs of tires and wheels installed with a large camber, as is the case on sports high-speed cars.

Как видно из представленного на фигуре 3, обод 1 и шина 2 имеют коническую форму. Диск колеса 3 при этом сохраняет стандартную конфигурацию.As shown in figure 3, rim 1 and tire 2 are tapered. At the same time, the disc of the wheel 3 retains the standard configuration.
