Title:
MECHANICAL-HYDRAULIC CONTINUOUSLY VARIABLE TRANSMISSION, AND THE METHOD THEREOF, AND VEHICLE MECHANICAL-HYDRAULIC CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2009/049514
Kind Code:
A1
Abstract:
A mechanical-hydraulic continuously variable transmission and a transmission
for vehicle are provided. The mechanical speed changing components of such transmission
includes an eccentric mechanism (2), a pushing disc (4), a fixing disc (3), and
a driving disc (5). The eccentric mechanism can adjust the eccentric amount between
the pushing disc and the power input shaft based on the load of the driving disc.
The hydraulic speed changing components of such transmission include a pump
runner (6) and a turbine (7) fixed to the driving disc. A power output shaft is coupled
to the turbine and extended out of the housing. Based on the advantage of high torque
ratio of the mechanical speed changing components at low speed ratio, the turbine
of the hydraulic speed changing components can be actuated and accelerated quickly.
When the speed ratio reaches a certain value, the main power transmitting path
is from the pump runner to the turbine of the hydraulic speed changing components.
Therefore, present invention combines the merits of the mechanical and hydraulic
speed changing components and has the advantage of high transmitting efficiency
in various operating conditions.
