Problems solved by technology

[0002] At present, no matter in the field of transmissions of traditional vehicles or new energy vehicles, the circuits and software that usually control the shifting of transmissions are relatively complicated, and one or more pressure sensors, speed sensors, proportional valves or quick on-off valves need to be configured, not only The cost is high and the space occupied is large. At the same time, the control of the shifting process is complex and the shifting time is long. There is a risk of interference to related signals. Even problems such as transmission damage will not only affect driving comfort, but also affect the service life of the transmission
With the development of new energy vehicles, the one-control two-linkage interlocking shift mechanism is of great significance to reduce the cost and volume of the transmission and improve the shift performance, but the corresponding device and control method for fluid control need to be further improved and perfected

Embodiment Construction

[0021] In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, the following specific embodiments are given and the accompanying drawings are described in detail as follows.

[0022] like Figures 1~5 As shown, the shifting fluid control device of a one-control two-speed transmission includes a casing 1, a driver 2, a planetary row 3, a fluid control device 4, and a clutch assembly 5. The fluid control device is outside the casing but communicates with the driver inside the casing. , the drive includes a piston 6, the pushing end of which is connected with the clutch assembly, the clutch assembly is slidably connected through the clutch drum and the ring gear of the planetary row, and is fixedly connected with the sun gear through the clutch hub.

[0023] In the embodiment of the present invention, the right end of the piston is the push end, and the right end of the piston is provided with a ratchet wheel 8 of...

Abstract

The invention relates to a one-control-two-gear transmission gear shifting fluid control device and a working method thereof.The one-control-two-gear transmission gear shifting fluid control device comprises a shell, a driver, a planet row, a fluid control device and a clutch assembly, the fluid control device is arranged outside the shell and communicated with the driver in the shell, the driver comprises a piston, and the pushing end of the piston is connected with the clutch assembly; according to the gear shifting fluid control device of the one-control-two-gear transmission, complex TCU, sensors and proportional valves do not need to be matched, the influence of the response time of an air path control element is avoided, and the gear shifting speed is high.

Description

technical field [0001] The invention relates to the field of planetary gear transmissions, in particular to a shifting fluid control device for a one-control two-speed transmission and a working method thereof. Background technique [0002] At present, no matter in the field of traditional automobile or new energy automobile transmission, the circuits and software that control the shifting of the transmission are usually complicated, and one or more pressure sensors, speed sensors, proportional valves or quick on-off valves need to be configured. The cost is high and the space is large. At the same time, the control of the shifting process is complicated and the shifting time is long. The relevant signals are at risk of being interfered. Even problems such as transmission damage will not only affect the driving comfort, but also affect the service life of the transmission. With the development of new energy vehicles, the one-control two-link interlock shifting mechanism is ...
