A invenção é contextualizada no campo da engenharia automotiva e mecânica, se destacando por sua aplicação em veículos com considerável peso bruto. [001] The present invention relates to an auxiliary system for steering cargo vehicles, more specifically an integrated electro-hydraulic or hydraulic system to optimize steering control and load distribution in cargo vehicles, such as trucks. The invention is contextualized in the field of automotive and mechanical engineering, standing out for its application in vehicles with considerable gross weight.
Antecedentes da Invenção Background of the Invention
[002] Veículos de carga, como caminhões, são fundamentais para o transporte de bens, materiais e mercadorias, desempenhando papel essencial em sistemas lógicos e cadeias de suprimentos globais. Tais veículos são caracterizados por sua capacidade de transportar cargas significativas e, consequentemente, apresentam estruturas robustas e sistemas complexos para garantir a operação segura e eficiente. [002] Cargo vehicles, such as trucks, are essential for the transportation of goods, materials and merchandise, playing an essential role in logical systems and global supply chains. Such vehicles are characterized by their ability to transport significant loads and, consequently, feature robust structures and complex systems to ensure safe and efficient operation.
[003] O sistema de direção de um veículo de carga consiste em um componente critico, encarregado de controlar a trajetória do veículo. Tal sistema é composto, fundamentalmente, por uma caixa de direção que recebe os inputs do motorista através do volante e transmite esses comandos para os eixos e rodas, permitindo assim o direcionamento do veículo. Em veículos de carga pesados, os sistemas de direção precisam ser robustos e precisos, dadas as massas envolvidas e as demandas operacionais. [003] The steering system of a cargo vehicle consists of a critical component, responsible for controlling the vehicle's trajectory. This system is fundamentally composed of a steering box that receives inputs from the driver through the steering wheel and transmits these commands to the axles and wheels, thus allowing the vehicle to be steered. In heavy cargo vehicles, steering systems need to be robust and precise, given the masses involved and the operational demands.
[004] Caminhões de grande porte frequentemente possuem múltiplos eixos, sendo estes cruciais para a distribuição equitativa da carga. A presença de vários eixos permite que o peso seja distribuído de forma mais uniforme ao longo da extensão do veículo, minimizando o estresse em componentes individuais e otimizando a estabilidade durante o transporte. [005] No entanto, o gerenciamento eficaz de múltiplos eixos também implica desafios, particularmente em relação ao desgaste de pneus e ao consumo de combustível. O aumento do número de pneus em contato com a superfície da estrada pode levar a uma resistência ao rolamento elevada, culminando em maior consumo de combustível e desgaste desigual de pneus. [004] Large trucks often have multiple axles, which are crucial for even load distribution. Having multiple axles allows weight to be distributed more evenly across the length of the vehicle, minimizing stress on individual components and optimizing stability during transport. [005] However, effective management of multiple axles also entails challenges, particularly in relation to tire wear and fuel consumption. The increased number of tires in contact with the road surface can lead to increased rolling resistance, culminating in higher fuel consumption and uneven tire wear.
[006] O desgaste desigual de pneus é um problema significativo na operação de veículos de carga, levando a custos adicionais com manutenção e substituição, além de aumentar os riscos de acidentes devido à perda de aderência e controle. A necessidade de um sistema de direção eficiente e um controle adequado dos eixos torna-se, assim, imperativa para minimizar estes problemas. [006] Uneven tire wear is a significant problem in the operation of freight vehicles, leading to additional maintenance and replacement costs, as well as increasing the risk of accidents due to loss of grip and control. The need for an efficient steering system and adequate axle control therefore becomes imperative to minimize these problems.
[007] O sistema de direção hidráulica, amplamente empregado em veículos de carga pesados, emprega fluido hidráulico para transmitir força do volante para as rodas, facilitando o manejo do veículo pelo motorista. Este sistema, por meio de uma bomba, cilindro e válvulas, multiplica a força aplicada pelo motorista, possibilitando uma direção suave e precisa de veículos de grande porte. [007] The power steering system, widely used in heavy cargo vehicles, uses hydraulic fluid to transmit force from the steering wheel to the wheels, making it easier for the driver to handle the vehicle. This system, by means of a pump, cylinder and valves, multiplies the force applied by the driver, enabling smooth and precise steering of large vehicles.
[008] Dado o contexto acima, há uma busca constante por inovações tecnológicas que possam otimizar o sistema de direção de veículos pesados, almejando aprimorar a integração e coordenação dos eixos, minimizando o desgaste de pneus e o consumo de combustível são de grande valor no campo da engenharia automotiva e mecânica. [008] Given the above context, there is a constant search for technological innovations that can optimize the steering system of heavy vehicles, aiming to improve the integration and coordination of the axles, minimizing tire wear and fuel consumption are of great value in the field of automotive and mechanical engineering.
[009] No estado da técnica, são conhecidas inovações focadas em melhorar os componentes individuais do sistema de direção, porém, há uma necessidade crescente por sistemas integrados que possam gerenciar de forma holística o comportamento de veículos de múltiplos eixos, considerando variáveis como peso da carga, condições da estrada e dinâmica veicular. [009] In the state of the art, innovations focused on improving the individual components of the steering system are known, however, there is a growing need for integrated systems that can holistically manage the behavior of multi-axle vehicles, considering variables such as load weight, road conditions and vehicle dynamics.
[010] A presente invenção surge como resposta a essa necessidade, propondo um sistema auxiliar de direção inovador, que integra e gerencia eficientemente os múltiplos eixos de veículos de carga pesados, visando a sustentabilidade, a segurança e a eficiência operacional. [010] The present invention arises as a response to this need, proposing an innovative auxiliary driving system, which efficiently integrates and manages the multiple axles of heavy cargo vehicles, aiming at sustainability, safety and operational efficiency.
Objetivos da Invenção Objectives of the Invention

[011] The present invention aims to provide an auxiliary system for steering cargo vehicles that significantly reduces tire wear and, consequently, reduces operating costs associated with tire maintenance and replacement, as well as improving vehicle safety during cargo transportation.
[012] A presente invenção também tem como objetivo proporcionar um sistema auxiliar para direção de veículos de carga que assegure uma distribuição de carga mais uniforme ao longo do veículo, trazendo estabilidade e minimizando o esforço em componentes estruturais e no pavimento.

Descrição Detalhada da Invenção Detailed Description of the Invention
[017] A principal abordagem da presente invenção consiste em um sistema auxiliar para direção de veículos de carga, visando diminuir o desgaste dos pneus, melhorar a distribuição de carga e reduzir o consumo de combustível do veículo de carga. [017] The main approach of the present invention consists of an auxiliary system for steering cargo vehicles, aiming to reduce tire wear, improve load distribution and reduce the cargo vehicle's fuel consumption.
[018] Tal sistema da presente invenção, em sua configuração preferencial, compreende pelo menos um cilindro hidráulico (01) integrado a um eixo dianteiro (06) do veículo de carga, um acumulador de pressão (02) e um módulo hidráulico ou eletro-hidráulico (03), conforme descritos detalhadamente a seguir. [018] Such a system of the present invention, in its preferred configuration, comprises at least one hydraulic cylinder (01) integrated into a front axle (06) of the cargo vehicle, a pressure accumulator (02) and a hydraulic or electro-hydraulic module (03), as described in detail below.
[019] O cilindro hidráulico (01) é um componente crítico do sistema da presente invenção, sendo integrado ao eixo dianteiro (06) do veículo de carga. Tal cilindro hidráulico (01) é configurado para transmitir força hidráulica, permitindo movimentos preciso e controlados do eixo dianteiro (06) e, consequentemente, das rodas (07) associadas às extremidades do eixo dianteiro (06). [019] The hydraulic cylinder (01) is a critical component of the system of the present invention, being integrated into the front axle (06) of the cargo vehicle. Such hydraulic cylinder (01) is configured to transmit hydraulic force, allowing precise and controlled movements of the front axle (06) and, consequently, of the wheels (07) associated with the ends of the front axle (06).
[020] Desta forma, o cilindro hidráulico (01) tem como função converter a energia hidráulica em energia mecânica, proporcionando a força necessária para movimentar e direcionar o veículo através do seu eixo dianteiro (06) e suas rodas (07), conforme ilustrado na Figura 1. [020] In this way, the hydraulic cylinder (01) has the function of converting hydraulic energy into mechanical energy, providing the force necessary to move and direct the vehicle through its front axle (06) and its wheels (07), as illustrated in Figure 1.
[021] O acumulador de pressão (02) também desempenha função vital no sistema, sendo configurado para manter a pressão do sistema quando a pressão da caixa de direção se aproxima de 0 bar, ou seja, assegurando a pressão do sistema para que o cilindro hidráulico (01) sempre possua a pressão necessária para converter a energia hidráulica em mecânica e orientar o veículo de carga. [021] The pressure accumulator (02) also plays a vital role in the system, being configured to maintain system pressure when the pressure of the steering box approaches 0 bar, that is, ensuring the system pressure so that the hydraulic cylinder (01) always has the necessary pressure to convert hydraulic energy into mechanical energy and steer the cargo vehicle.
[022] O módulo hidráulico ou eletro-hidráulico (03) consiste em um dispositivo de segurança avançado incorporado ao sistema, sendo responsável por monitorar e controlar a pressão do óleo, garantindo que a pressão não ultrapasse a pressão desejada. Em sua configuração preferencial, o módulo hidráulico ou eletro-hidráulico (03) compreende uma válvula de alívio integrada, evitando possíveis danos ou falhas ao sistema através deste controle da pressão. [022] The hydraulic or electro-hydraulic module (03) consists of an advanced safety device incorporated into the system, responsible for monitoring and controlling the oil pressure, ensuring that the pressure does not exceed the desired pressure. In its preferred configuration, the hydraulic or electro-hydraulic module (03) comprises an integrated relief valve, preventing possible damage or failures to the system through this pressure control.
[023] Para veículos que possuem mais eixos de direção além do eixo dianteiro (06), o sistema da presente invenção também compreende eixos adicionais (04, 05) que podem ser instalados de maneira interligada ao cilindro hidráulico (01) através de uma série de tubos e mangueiras. Estes eixos adicionais (04, 05) associados ao cilindro hidráulico (01) permitem a distribuição equitativa da carga, de modo a orientar o veículo também através dos eixos adicionais (04, 05), conforme ilustrado na Figura 2. [023] For vehicles that have more steering axles in addition to the front axle (06), the system of the present invention also comprises additional axles (04, 05) that can be installed in an interconnected manner to the hydraulic cylinder (01) through a series of tubes and hoses. These additional axles (04, 05) associated with the hydraulic cylinder (01) allow for equitable distribution of the load, so as to also steer the vehicle through the additional axles (04, 05), as illustrated in Figure 2.
[024] Desta forma, para os veículos de carga que compreendem múltiplos eixos, o sistema da presente invenção compreende eixos adicionais (04, 05) além do cilindro hidráulico (01), de modo a também controlar os múltiplos eixos e garantir um controle efetivo e preciso do veículo de carga. [024] Thus, for cargo vehicles comprising multiple axles, the system of the present invention comprises additional axles (04, 05) in addition to the hydraulic cylinder (01), so as to also control the multiple axles and ensure effective and precise control of the cargo vehicle.
[025] Todos os componentes do sistema auxiliar da presente invenção são associados por meio de tubos e mangueiras, que permitem a transmissão fluida e eficiente do óleo hidráulico entre os componentes. É por meio desta rede de tubos e mangueiras que o óleo se movimenta, transferindo a pressão e permitindo o controle preciso dos movimentos do veículo de carga. [025] All components of the auxiliary system of the present invention are associated by means of tubes and hoses, which allow the fluid and efficient transmission of hydraulic oil between the components. It is through this network of tubes and hoses that the oil moves, transferring the pressure and allowing precise control of the movements of the cargo vehicle.
[026] Além disso, o sistema auxiliar é configurado para se integrar de forma harmoniosa com a caixa de direção (08) original do veículo, de modo que, a caixa de direção (08) recebe os comandos do motorista e, através do sistema auxiliar da presente invenção, transmite esses comandos de maneira otimizada aos vários eixos do veículo de carga, proporcionando um controle mais eficaz e uma condução mais suave. [026] In addition, the auxiliary system is configured to integrate harmoniously with the vehicle's original steering box (08), so that the steering box (08) receives the driver's commands and, through the auxiliary system of the present invention, transmits these commands in an optimized manner to the various axles of the cargo vehicle, providing more effective control and smoother driving.
[027] No funcionamento do sistema auxiliar, a direção do veículo de carga é assistida pela ação coordenada de todos os componentes, de modo que, quando o motorista gira o volante, a caixa de direção (08) transmite este movimento ao cilindro hidráulico (01) por meio de óleo hidráulico através da rede de tubos e mangueiras, enquanto o cilindro hidráulico (01) interage com os eixos adicionais (04 e 05) transmitindo este movimento e distribuindo de forma uniforme a carga. [028] Sendo assim, o sistema auxiliar da presente invenção pode ser aplicado em veículos de carga com diferentes configurações. Apenas a título exemplificative, e não limitativo, a Figura 1 ilustra um veículo de carga com uma configuração de eixos e rodas com Peso Bruto Total (PBT) de 22,5 toneladas, enquanto a Figura 2 ilustra um veículo de carga com uma configuração de eixos e rodas com Peso Bruto Total (PBT) de 31 ,5 toneladas, podendo ser aplicado em qualquer tipo de veículo de carga e sua configuração. [027] In the operation of the auxiliary system, the steering of the cargo vehicle is assisted by the coordinated action of all components, so that, when the driver turns the steering wheel, the steering box (08) transmits this movement to the hydraulic cylinder (01) by means of hydraulic oil through the network of tubes and hoses, while the hydraulic cylinder (01) interacts with the additional axles (04 and 05) transmitting this movement and evenly distributing the load. [028] Thus, the auxiliary system of the present invention can be applied to cargo vehicles with different configurations. By way of example only, and not as a limitation, Figure 1 illustrates a cargo vehicle with an axle and wheel configuration with a Gross Vehicle Weight (GVW) of 22.5 tons, while Figure 2 illustrates a cargo vehicle with an axle and wheel configuration with a Gross Vehicle Weight (GVW) of 31.5 tons, and can be applied to any type of cargo vehicle and its configuration.
[029] Desta forma, tendo sido o sistema auxiliar para direção de veículos de carga da presente invenção, resta evidente que a mesma cumpre com os objetivos propostos, assegurando uma direção mais precisa e um desgaste menor dos pneus, reduzindo o impacto sobre o pavimento e otimizando o consumo de combustível, estando alinhado com princípios de sustentabilidade e eficiência operacional. [029] Thus, given that the auxiliary system for steering cargo vehicles is the present invention, it is clear that it meets the proposed objectives, ensuring more precise steering and less tire wear, reducing the impact on the pavement and optimizing fuel consumption, in line with the principles of sustainability and operational efficiency.
[030] Além disso, o sistema auxiliar para direção de veículos de carga da presente invenção representa um avanço significativo na tecnologia de sistemas de direção para veículos de carga, trazendo solução inovadora e eficiente para os desafios enfrentados por veículos de múltiplos eixos no cenário atual de transporte de cargas. [030] Furthermore, the auxiliary system for steering cargo vehicles of the present invention represents a significant advance in the technology of steering systems for cargo vehicles, bringing an innovative and efficient solution to the challenges faced by multi-axle vehicles in the current cargo transportation scenario.
