Embodiment Construction

[0018] The present invention relates to a braking energy recovery system which can be installed as standard equipment on new vehicles or as a retrofit to existing vehicles. Through the use of variable displacement hydraulic pumps and motors, the recovered energy can be adjusted according to braking demand and the stored energy can be adjusted according to the power demand from auxiliary systems. Furthermore, in one embodiment of the invention, the brake energy recovery system can also be used to boost the vehicle during acceleration.

[0019] see now figure 1 , which schematically depicts the braking energy recovery system 10 of the present invention. For better understanding, the brake energy recovery system 10 is shown mounted on a powertrain 12 of a vehicle. figure 1 The components of powertrain 12 shown in are: internal combustion engine 14 and transmission 16 , which together form an engine-transmission assembly 18 ; and propshaft 20 , which connects a wheel set 22 to t...

Abstract

A braking energy recovery system adapted for use on a vehicle and a vehicle having such a system installed. The vehicle has an engine-transmission assembly, a driveshaft, a braking system and an auxiliary system. The energy recovery system comprises a first pump, a hydraulic accumulator and a hydraulic motor. The first pump is a variable displacement hydraulic pump. The hydraulic accumulator is connected to the first pump and is operative to store hydraulic fluid under pressure. The hydraulic motor is hydraulically connected to the accumulator to receive hydraulic fluid. The motor is adapted to drive a second hydraulic pump, which is hydraulically connected to the auxiliary system, using hydraulic energy stored in the accumulator.

Description

technical field [0001] The present invention generally relates to the field of energy efficiency in vehicles. More specifically, the invention relates to a braking energy recovery system for use on a vehicle having an auxiliary system capable of at least partially powering said auxiliary system. Background technique [0002] Brake energy recovery systems - also known as hybrid systems - have been known for some time in the field of electric vehicles such as cars and light trucks. In most applications, energy recovered during braking that would otherwise be dissipated as heat is repurposed to drive a stopped vehicle. [0003] Refuse trucks are well suited for the application of brake energy recovery systems. In fact, a typical duty cycle of a refuse truck in collection mode is characterized by a high frequency of stop and go cycles and a low average speed. Furthermore, the energy consumption required for frequent use of hydraulic auxiliary systems such as refuse compactors...
