Electricity-oil dual-power laneway loader-digger transmission separating mechanism and chassis driving device

Abstract

The invention relates to a driving and separating mechanism and a chassis driving device of a laneway excavation loader using both electricity and petrol. The driving and separating mechanism comprises an internal combustion engine, wherein an output shaft, a clutch and a shaft joint of the internal combustion engine, a main drive shaft of the driving mechanism, and an output shaft of an electric motor are sequentially and coaxially connected in a transmission way; the chassis driving device comprises a chassis, the driving mechanism positioned on the chassis comprises an coaxial double-power driving device, a clutch and a gear-box, and the coaxial double-power driving device consists of the electric motor and the internal combustion engine. The driving and separating mechanism and the chassis driving device adopt the coaxiality of the electric motor and the output shaft of a diesel engine as double power to be used in a matching way, thereby not only ensuring the normal running and transportation operation of a locomotive, but also being convenient for flexibly adopting electrical power as power during excavation and loading operation. The diesel engine is coaxial with the electric motor, and is controlled by the clutch. The internal combustion engine brings larger power which is convenient for transportation and running during four-wheel driving. The invention has the advantages of simple structure and convenient and flexible operation, and is particularly applicable to numerous popularization and application in excavation and loading industry.

Description

1. Technical field: [0001] The invention relates to a driving chassis part for a loader in the field of roadway excavation, in particular to a transmission separation mechanism and a chassis driving device for a roadway digging loader with dual-purpose electric and oil. 2. Background technology: [0002] At present, the locomotives used in the field of excavation, loading and transportation all use internal combustion engines as the main power (for example, heavy backhoe loaders are driven by diesel engines). Using internal combustion engines as transportation power has its advantages: the fuel used in transportation tools is easy to carry, and it can be carried by itself. Enough fuel to go a long way. However, for small-scale operations with relatively fixed positions, the internal combustion engine has its disadvantages: it needs to burn more expensive fuel, discharge exhaust gas, pollute the environment, make a lot of noise, and be inconvenient to operate. Electric locom...

Problems solved by technology

However, for small-scale operations with relatively fixed positions, the internal combustion engine has its disadvantages: it needs to burn more expensive fuel, discharge exhaust gas, pollute the environment, make a lot of noise, and is not very convenient to operate

[0003] In the field of excavation, loading and transportation, it is usually necessary to combine excavation, loading and transportation. The current backhoe loader only works together with an internal combustion engine (such as a diesel engine) and a gear pump driven by an internal combustion engine, that is, it relies on The internal combustion engine is the power for walking, and the internal combustion engine is still used to drive the gear pump for excavation and loading during excavation and loading, resulting in inflexible operation during excavation and loading operations, low energy utilization rate, and the defects of exhaust gas and noise polluting the environment
