The transmission case comprises a case body and a gear transmission mechanism, wherein, the gear transmission mechanism comprises a first-gear driving shaft (9), a second-gear driving shaft (2), a driven shaft (5), an output shaft (12), a second-gear driving gear (3), a first-gear driven gear (8), a second-gear driven gear (4), a gear shift sliding gear sleeve (6) and an output sliding gear sleeve (11); the first-gear driving shaft (9) and the second-gear driving shaft (2) are installed in the case body (1); the driven shaft (5) is positioned between the two driving shafts; the output shaft (12) is installed on the case body (1); the second-gear driving gear (3) is fixed on the second-gear driving shaft (2); the first-gear driven gear (8) and the second-gear driven gear (4) are sheathed with the driven shaft (5) and respectively engaged with a first-gear driving gear (14) and a second-gear driving gear (3); the gear shift sliding gear sleeve (6) is arranged on the driven shaft (5) and provided with a gear shift transmission fork (7); and the output sliding gear sleeve (11) is arranged on the output shaft (12) and provided with an output transmission fork (10). The utility model can be used in hydraulic excavators and other engineering machines.
Description
Technical field:
The utility model relates to a kind of speed change gear, relates in particular to a kind of walking gearbox of hydraulic shovel.
Background technique:
The walking gearbox is one of vitals of hydraulic shovel, and whether its performance quality, structure be reasonable, and can will be directly connected to excavator cruising and work.At present, mainly there are defectives such as complex structure, gear-change operation are required great effort, shift smoothness is relatively poor in the walking gearbox of hydraulic shovel.
Summary of the invention:
At the above-mentioned defective that exists in the prior art, the utility model aims to provide the steadily transmission case of hydraulic shovel double motor walking easily of a kind of simple and compact for structure, gear shift.
To achieve these goals, the utility model by the following technical solutions: it comprises casing, is arranged on the gear drive in this casing; Described gear drive is by second gear driving shaft and one grade of driving shaft of being installed in side by side in the casing, be installed in the driven shaft between above-mentioned two driving shafts in the casing, be installed on the casing and an end is inserted into the output shaft of this driven shaft end, be fixed on the second gear driving gear on the second gear driving shaft, sky is enclosed within the second gear driven gear that meshes with this second gear driving gear on the driven shaft, sky is enclosed within the first speed driven gear that meshes with the one grade of driving gear that is located on one grade of driving shaft on the driven shaft, between second gear driven gear and first speed driven gear and by internal spline, be arranged on gear shift sliding gear collar on the driven shaft, the reverse shift fork that connects firmly with this gear shift sliding gear collar, be arranged on output sliding gear collar on the output shaft by internal spline, the output shift fork that connects firmly with this output sliding gear collar constitutes.
The other end at driven shaft is provided with brake assembly.
Compared with the prior art, therefore the utility model has advantages such as simple and compact for structure, that gear shift steady, operation is light, the car load driving safety is reliable owing to adopted technique scheme.
