Abstract

The present invention relates to a novel full hydraulic wheel type excavator shifting with hydraulic power. A cab, a hydraulic controlling device and an excavating device are arranged on a wheel type chassis driven by a front bridge and a back bridge, and the walking gearbox in the wheel type chassis adopts a hydraulic power shifting gearbox containing a casing body (1) as well as an axle I (2), an axle II (3), an axle III (4), an axle IV (5), an axle V (6) etc., the axle I (2) is connected with a hydraulic motor (7) and is provided with a spline gear (8), the axle II (3) is provided with a low-speed brake gear(9) and a friction type hydraulic clutch I (10), and the axle III (4) is provided with a double-linked gear I (12) , a friction type hydraulic clutch II (13), and a high-speed clutch gear (14), the axle IV (5) is connected with a front driving bridge (21) in parallel and is provided with a low-speed double-linked gear (16), and the axle V (6) is connected with a back driving bridge (22) and is provided with a high-speed double-linked gear (17); a shifting gear (18) connected with a shifting fork (19) is arranged between the axle IV (5) and the axle V (6). The present invention has the advantages of hydraulic power shifting, high speed driving back bridge, low speed driving front bridge and back bridge, convenient manipulation, etc.

Description

technical field [0001] The invention relates to a construction machine, in particular to a full hydraulic wheel excavator with hydraulic power shifting. Background technique [0002] As a multi-purpose construction machine, excavators have been widely used. Especially in recent years, small excavators have developed rapidly. Wheeled excavators are more and more popular among users due to their strong mobility and no need for special transportation tools. [0003] At present, most of the walking parts of domestic wheeled excavators use high-pressure hydraulic oil to drive a variable motor to drive a gearbox to achieve variable speed. The gearbox is divided into two gears of high and low speed, with front and rear output, and uses the forward and reverse rotation of the motor to realize forward and backward. But the gearbox is mainly an imported gearbox assembly, or a loader gearbox. Imported gearboxes are costly and cost-effective; loader gearboxes are bulky, have many ge...
