Abstract

A wheel excavator with an automatic speed changing device comprises a vehicle body, an excavation arm, driving wheels, a driving system and a transmission system. The driving system comprises an engine, a clutch and a speed changing device, and the engine, the clutch and the speed changing device are connected in sequence through a transmission shaft. The speed changing device is the automatic speed changing device, the automatic speed changing device comprises a speed changer body and a speed changer cover arranged on the speed changer body, a small speed changer cover is arranged on the upper portion of the speed changer cover, and two small short-stroke hydraulic cylinders are used for drive a gear shifting mechanism to act. The problems that mechanical transmission and manual speed changing are adopted in a transmission system of a current excavator, the flexibility degree is not enough, and operation is inconvenient are solved. The wheel excavator has the advantages of being high in flexibility degree, high in intelligent degree, and convenient to operate.

Description

technical field [0001] The invention relates to a wheeled excavator, in particular to a wheeled excavator with an automatic transmission device. Background technique [0002] Excavator is a multi-purpose earth-rock construction machine, mainly for earth-rock excavation and loading, and can also perform land leveling, slope repair, hoisting, crushing, demolition, ditching and other operations, so it is used in road construction such as roads and railways, bridge construction, It has been widely used in urban construction, airport port and water conservancy construction. [0003] Currently commonly used excavators generally include wheeled excavators and crawler excavators. Usually, the transmission system of wheeled excavators is mechanical transmission, manual transmission is similar to the transmission system of ordinary freight cars, and there is no automatic transmission of wheeled excavators. At present, the transmission system of wheeled excavators still relies on the ...
