Embodiment 1

[0030] exist figure 1 In the shown embodiment, a hydraulic transmission device includes a housing 1, a front cover 2 and a rear cover 3 cooperating with the housing 1, the housing 1 and the front cover 2 or the rear cover 3 are of a split structure, and the housing A cavity 4 is provided on the body 1, and a transmission mechanism is provided inside the cavity 4. The transmission mechanism includes an input shaft 5, an output shaft 6, a rotor 7 and a swivel 8. The rotor 7 and the input shaft 5 are separate structures, and the swivel 8 It is a separate structure from the output shaft 6, and the housing is a separate structure from the front cover or rear cover. The rotor 7 is arranged on the input shaft 5 and rotates together with the input shaft 5, the swivel 8 is arranged on the outside of the rotor 7 and connected with the output shaft 6, the swivel 8 rotates together with the output shaft 6, and the rotor 7 is provided with several sliding vanes 9. The inner surface of the...

Embodiment 2

[0034] exist Image 6 In the shown embodiment, a hydraulic transmission device includes a housing 1, a front cover 2 and a rear cover 3 cooperating with the housing 1, the housing 1 and the front cover 2 or the rear cover 3 are of a split structure, and the housing A cavity 4 is provided on the body 1, and a transmission mechanism is provided inside the cavity 4. The transmission mechanism includes an input shaft 5, an output shaft 6, a rotor 7 and a swivel 8. The rotor 7 and the input shaft 5 are separate structures, and the swivel 8 and the output shaft 6 are split structures, and the housing and the front cover or rear cover are split structures. The rotor 7 is arranged on the input shaft 5 and rotates together with the input shaft 5. The swivel 8 is arranged on the outside of the rotor 7 and connected with the output shaft 6. The swivel 8 rotates together with the output shaft 6. The rotor 7 is provided with several Towards the sliding blades 9, the inner surface of the s...

Embodiment 3

[0038] The content of embodiment 3 is basically the same as that of embodiment 1, except that the transmission mechanism does not have a bimetallic side plate 10, which can simplify the structure of the hydraulic transmission device. The swivel and the output shaft are integrally structured, and the housing is integrally structured with the front cover or the rear cover.

[0039] The swivel of the hydraulic transmission device is connected to the output shaft and can rotate together with the output shaft. The swivel and the rotor compress the hydraulic oil along the contour of the swivel to transmit the rotational force to the swivel. Since the torque is equal to the pressure x displacement , so controlling the input pressure controls the output torque.

[0040] When the hydraulic transmission is in use, the input shaft, rotor and vanes rotate together, and the swivel, pressure side plate and output shaft rotate together. Since the inner surface of the swivel 8 is provided wi...

Abstract

The invention discloses a hydraulic transmission device which comprises a housing, a front cover and a rear cover which are matched with the housing, and a transmission mechanism arranged in a cavity, wherein the cavity is arranged on the housing; the transmission mechanism comprises an input shaft, an output shaft, a rotor and a rotating ring; the rotor is arranged on the input shaft, and rotates with the input shaft; the rotating ring is arranged outside the rotor, and connected with the output shaft; the rotating ring and the output shaft rotate together; a plurality of sliding blades are arranged on the rotor; and at least one gradual extending section and at least one gradual shrinking section are arranged on the inner surface of the rotating ring in a rotating direction. The transmission device can control the magnitude of output torque and rotating speed by controlling fluid parameters, can achieve torque-free output idling, and is less in energy consumption, stable to start, high in efficiency, simple in structure, safe and convenient to operate, long in service life, high in power density and wide in application.

Description

technical field [0001] The invention relates to the technical field of transmission, in particular to a hydraulic transmission device. Background technique [0002] The working principle of the hydraulic clutch is simple, it is revolutionized by the hydraulic vane pump. Usually people's thinking is taken for granted on the working principle of the vane pump, that is, the stator is fixed while the rotor and vanes rotate, thereby generating high-pressure oil output. If the pressure port is blocked, the energy has nowhere to release, and an accident will occur. [0003] Chinese patent literature (publication date: August 4, 2010, publication number: CN 101796317A) discloses hydraulic components, especially for the pressure pipeline arranged between the master cylinder and the slave cylinder of a hydraulic clutch operating device , the hydraulic element has a housing with a hydraulic connection on the master cylinder side and a hydraulic connection on the slave cylinder side, ...
