DEVELOPMENT OF A HYDRAULIC DRIVE FOR A NOVEL HYBRID DIESEL-HYDRAULIC SYSTEM FOR LARGE COMMERCIAL VEHICLES

A Novel Energy Recovery System for Parallel Hybrid Hydraulic Excavator

Hydraulic excavator energy saving is important to relieve source shortage and protect environment. This paper mainly discusses the energy saving for the hybrid hydraulic excavator. By analyzing the excess energy of three hydraulic cylinders in the conventional hydraulic excavator, a new boom potential energy recovery system is proposed. The mathematical models of the main components including b...

DEVELOPMENT OF A DC MOTOR ASSISTED HYDRAULIC BRAKING SYSTEM FOR AUTOMOTIVE USE

ABSTRACT: Deceleration or stopping the vehicle without any diving and lateral acceleration is essential to develop an effective braking system. The hydraulic braking system with intelligent braking called Antilock Braking system (ABS) and Electronic Stability Control (ESC) has been introduced.  However, due to the insufficient human effort, the ABS and ESC to some extent, not function well...

Electro-hydraulic Braking System for Autonomous Vehicles

−Reducing the number of traffic accidents is a declared target of most governments. Since dependence on driver reaction is the main cause of road accidents, it would be advisable to replace the human factor in some driving-related tasks with automated solutions. In order to automate a vehicle it is necessary to control the actuators of a car, i.e., the steering wheel, accelerator, and brake. Th...
