Embodiment Construction

[0037]As shown in the figure, the continuously variable hydraulic transmission of the present invention includes an active pump a and a driven motor b. Both the active pump a and the driven motor b include a first base 1 and a second base 2. The first base 1 and the second base body 2 are correspondingly provided with a first accommodating cavity and a second accommodating cavity, and a first rotor cylinder and a second rotor cylinder are correspondingly rotatably arranged in the first accommodating cavity and the second accommodating cavity, The first rotor cylinder block and the second rotor cylinder block are respectively eccentrically provided with a first plunger cavity and a second plunger cavity; as shown in the figure, the first rotor cylinder block 3 and the second rotor cylinder block 4 respectively pass through corresponding The bearings (including angular contact bearings or thrust bearings) are arranged on the corresponding first base body 1 and second base body 2 throu...

Abstract

The invention discloses a continuously variable hydraulic transmission, which comprises a driving pump and a driven motor, the central axis of the first accommodation chamber and the central axis of the second accommodation chamber intersect and the angle between them is adjustable; the plunger The assembly includes a first plunger matched with the first plunger cavity and a second plunger matched with the second plunger cavity; the medium outlet of the active pump communicates with the medium inlet of the driven motor and is used to drive the driven motor; The present invention utilizes the V-shaped base structure with adjustable angle, and the displacement of the active pump and the driven motor can realize positive and negative volume stepless adjustment and electromechanical energy conversion without changing the rotation direction and working fluid path, thereby not only realizing variable speed It can also realize the three-phase energy exchange of mechanical, electrical and hydraulic, not only the gearbox but also the power source and energy storage device, which greatly expands the working condition adaptability of the entire power system.

Description

Technical field[0001]The invention relates to the transmission drive field, in particular to a stepless hydraulic transmission.Background technique[0002]Transmission is one of the necessary equipment in the field of mechanical transmission, including vehicles, machine tools and so on. In the prior art, transmissions include manual transmissions and automatic transmissions; automatic transmissions are commonly used due to simple operation, strong comfort and ease of operation; automatic transmissions have many types, but they all tend to change gears without frustration It has high comfort and high transmission efficiency. In the prior art, a representative automatic transmission with higher comfort is a CVT structure, but compared with other commonly used automatic transmissions, the transmission efficiency does not have an advantage. The gearbox of mechanical structure has limited transmission range, high maintenance and use cost, and is limited to mechanical transmission. It has a...
