Description
Technical field
The utility model relates to a kind of gearbox that is used for loader.
Background technique
The gearbox that is used for loader at present is manual transmission, because loader speed change in operation process is frequent, and manual gear shifting operation inconvenience, driver's the amount of labour is big, and easily generation is tired, causes working efficiency to descend.Traditional all kinds of automatic transmission case are difficult to be applied on the loader owing to high costs.
The model utility content
Technical problem to be solved in the utility model provide a kind of rational in infrastructure, with low cost, control conveniently, the loader electrically controlled gearbox of reliable in function.
For solving the problems of the technologies described above, the technical solution of the utility model is: the loader electrically controlled gearbox, comprise casing, the parallel power input shaft that is equipped with in the described casing, jack shaft and pto, described power input shaft has and stretches out described casing outside and be used for the input end that is connected with power plant, be installed with the input shaft fixed gear on the described power input shaft, the jack shaft fixed gear that is meshed with described input shaft fixed gear is installed on the described jack shaft, also be set with top gear clutch gear and bottom gear clutch gear on the described jack shaft, the top gear fixed gear that is meshed with described top gear clutch gear is installed on the described pto, the bottom gear fixed gear that is meshed with described bottom gear clutch gear also is installed on the described pto; Be respectively equipped with a hydraulic coupling between described top gear clutch gear and the jack shaft fixed gear and between described bottom gear clutch gear and the jack shaft fixed gear.
As optimized technical scheme, described power plant are oil hydraulic motor.
Owing to adopted technique scheme, the beneficial effects of the utility model are: owing to only be provided with the high, low speed retaining in the gearbox, simple in structure, reliable transmission, rate of fault are low; The switching of advancing, retreat retaining realizes by the change that the oil hydraulic motor that links to each other with power input shaft turns to because the oil hydraulic motor commutation is convenient, so gearbox to advance, retreat the switching of retaining very quick; Because top gear clutch gear and bottom gear clutch gear are controlled clutch by hydraulic coupling, realize the switching of high, low speed retaining, make easy to operately, greatly reduce driver's the amount of labour.Therefore, the utlity model has advantage rational in infrastructure, with low cost, as to control convenience, reliable in function.
