Design and Development of an Inbuilt Jack System for Vehicle an Integrated Approach Using Brake Oil Reservoir Pressure for Efficient Lifting Mechanism

This research presents the design and development of an inbuilt hydraulic jack system integrated directly into a vehicle chassis to streamline the process of vehicle maintenance, vehicle washing, tyre replacement, and anywhere requires to lifting of the vehicle or a single tyre. The proposed mechanism utilizes hydraulic pressure from the brake oil reservoir to actuate lifting cylinders, eliminating the need for external jacks or manual effort. The system comprises a hydraulic cylinder assembly, control valve unit, and dedicated lifting arms designed for structural stability and ease of operation. Upon activation through a control switch, pressure is directed to the lifting mechanism, enabling smooth elevation of the vehicle. This compact design ensures minimal modification to the vehicle structure and offers significant advantages in terms of time efficiency, safety, and roadside convenience. The inclusion of safety features such as check valves and mechanical locks ensures isolation from the main braking system, making it reliable during real-time use. The model demonstrates an effective, low-cost, and user-friendly alternative to conventional tyre replacement methods in automobiles.
