Embodiment Construction

[0039] figure 1 The hydraulic circuit of the vehicle is shown. Advantageously, but not limitatively, the vehicle V is a light vehicle such as a car.

[0040] The vehicle V comprises a frame and two axles 10, 20, each with two wheels, 12, 13 and 22, 23, respectively.

[0041] The two axles 10, 20 define the main direction D of the frame of the vehicle.

[0042] The vehicle further comprises a main engine M (usually a hot engine), a clutch 2 and a gearbox 3 which connects the engine to one of the two shafts to provide drive of the shafts.

[0043] exist figure 1 , the main engine drives the front axle 10 (referred to as the drive axle), while the rear axle 20 is referred to as the driven axle.

[0044] The vehicle further comprises hydraulic assistance, advantageously a hydrostatic power transmission from the drive shaft 10 to the driven shaft 20 . The vehicle thus comprises a first hydraulic machine 40 mounted on the one hand to the frame and on the other hand to the drive...

Abstract

The invention relates to a unit integrated with the boost function and the groove function within the housing of a hydraulic press. The unit (100) comprises a hydraulic press adapted to be connected to a hydraulic circuit; a boost pump used for boosting up the hydraulic circuit; and a housing (5) that defines an interior volume. The unit is characterized in that the hydraulic press and the boost pump are arranged in the interior volume of the housing. The interior volume of the housing is composed of a main region (55) and a sub region (56). The main region (55) is used for receiving the boost pump, wherein when the main region is immersed in the oil, the boost pump is immersed in the oil. The sub region (56) is in fluid communication with the main region and is adapted to receive the hydraulic press. The present invention also relates to vehicle comprising the above unit.

Description

technical field [0001] The present invention relates to the field of hydrostatic transmission, in particular to the field of casing structures for hydraulic machines. [0002] A particular application of the present invention is in hydrostatic assistance in vehicles. Background technique [0003] Performing a hydrostatic transmission on a vehicle requires the installation of various elements, among which are one or more hydraulic machines that can be operated in the form of pumps or motors, systems for oil distribution, pressurization, filtration and storage. [0004] The result of these multiple components is a huge burden of baggage, which is a problem in vehicle design. [0005] Furthermore, these individual elements have to be connected, which creates a multiplication of hydraulic hoses and electrical connections, which in particular creates problems with hoses falling off. [0006] In order to limit the cumbersome burden associated with the elements and their connecti...
