Abstract

The invention discloses a double-axis friction plate type brake clutch for a planetary transmission with a double-turbine torque converter, and belongs to an engineering mechanical component. The double-axis friction plate type brake clutch is used for gear shifting control and is mounted on an intermediate input shaft assembly in the planetary transmission with the double-turbine torque converter. A piston is movably mounted on the intermediate input shaft assembly via a piston ring; the intermediate input shaft assembly is connected with a clutch hub by a spline, and a spacer bush and an isolating ring are arranged between the intermediate input shaft assembly and the clutch hub; the clutch hub is connected with a driven friction plate by a spline, and a clutch shell is connected with a driving friction plate by a spline; a pressed plate is connected with the clutch hub by a spline and is positioned by the aid of a clamp ring A and a clamp ring B; a spring is arranged between the clutch hub and the piston, a piston oil inlet hole and a cooling oil hole are further formed in the intermediate input shaft assembly, and screw plugs are respectively arranged at one end of the piston oil inlet hole and one end of the cooling oil hole. The double-axis friction plate type brake clutch has the advantage that problems of violent gear shifting impact and poor operation comfort of an existing planetary transmission with a double-turbine torque converter for a loader can be solved.

Description

technical field [0001] The invention belongs to construction machinery components, in particular to a two-shaft friction disc brake clutch used in a loader twin-turbine torque converter planetary gearbox. Background technique [0002] At present, most of the gearboxes used in domestically produced ZL series loaders are planetary power shift gearboxes. This gearbox uses a twin-turbine hydraulic torque converter. The first gear cooperates with the two gears of the second shaft (that is, the overrunning clutch), and the torque is collected and input to the gearbox. The torque transmitted by the gearbox is large, which can realize automatic switching between high-speed light load and low-speed heavy load. It is easy to operate and widely used. [0003] But this kind of gearbox is assembled on the whole machine, and there are generally the shortcomings of large shifting impact and poor operating comfort, and the service life of the whole machine is also seriously reduced due to ...
