Embodiment Construction

[0029] figure 1 A hybrid vehicle is shown comprising a combustion engine 2 directly connected to a first hydraulic pump 4 that receives supply fluid through a low pressure circuit 16 and returns it at high pressure to the high pressure circuit 6 .

[0030] The low pressure circuit 16 and the high pressure circuit 6 are connected to a hydraulic command block 8 which controls the hydraulic motor 18 and the second hydraulic pump 26 .

[0031] A hydraulic command block 8 is mounted at the front of an elongated high pressure accumulator 10, longitudinally under the floor of the vehicle. A low-pressure accumulator 14 extending in lateral direction and disconnected from the high-pressure accumulator is mounted under the vehicle behind the high-pressure accumulator.

[0032] The hydraulic command block 8 is directly connected to a high pressure accumulator 10 via an internal high pressure line and to a low pressure accumulator 14 via an external low pressure line 12 .

Abstract

A hydraulic module designed to be mounted on a hydraulic hybrid vehicle, characterised in that it forms a rigid and compact assembly comprising a body (32) receiving the high- and low-pressure accumulators intended to supply traction motors of the vehicle, comprising a generally parallelepipedal shape, and having attachment means designed to be fixed under a floor at the rear of the vehicle.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from French application 1350109, filed January 7, 2013, the content (text, drawings and claims) of which is hereby incorporated by reference. technical field [0003] The invention relates to a module for a hybrid vehicle comprising a high-pressure and a low-pressure hydraulic accumulator, and a hybrid vehicle comprising said module. Background technique [0004] Certain hybrid vehicles have an internal combustion engine that drives a hydraulic pump to store energy by charging accumulators with pressurized fluid, and a hydraulic motor that drives the traction wheels of the vehicle, supplied by these accumulators. These vehicles also include hydraulic pumps connected to the traction wheels to recover the vehicle's kinetic energy during braking and thereby recharge the accumulators. [0005] Hydraulic accumulators may include, inter alia, high pressure accumulators receiving pressure fro...
