Modular electric drive travel unit and multi-axis travel unit

Abstract

The invention belongs to the technical field of special electric drive vehicles, and discloses a modular electric drive travel unit which comprises a modular vehicle frame assembly, drive motors, wheel-side transmission shafts, wheel hub and brake assemblies, vehicle wheels, a double-wishbone independent suspension, motor coolers and a motor controller. The modular vehicle frame assembly comprisestwo longitudinal beams, two motor mounting side plates, a suspension transverse beam, two motor mounting transverse beams and a bottom protection plate; the two motor mounting side plates are fixed onto the inner side surfaces of the two longitudinal beams, and two ends of the suspension transverse beam are fixed onto the longitudinal beams by the aid of fixing components; two ends of each motormounting transverse beam are fixed to positions between the two motor mounting side plates, the bottom protection plate is fixed to the bottoms of the motor mounting transverse beams, and motor mounting frame structures are formed; the drive motors are fixed into the motor mounting frame structures and are connected with the vehicle wheels sequentially by the wheel-side transmission shafts and thewheel hub and brake assemblies; the double-wishbone independent suspension is arranged between the wheel hub and brake assemblies and the modular vehicle frame assembly in a connected manner.

Description

technical field [0001] The invention relates to the technical field of special electric drive vehicles, in particular to a modular electric drive driving unit and a multi-axle driving unit. Background technique [0002] In the prior art, in the layout setting of the vehicle, the focus is on the structure and layout of the drive motor. The layout of other structures is usually based on the type and use of different vehicles, and is set around the drive structure; resulting in suspension, vehicle frame and electric motors. The coordination of the driving device is not stable, especially for special vehicles such as multi-axle vehicles, it cannot meet the generalization and modularization requirements of multi-axle electric drive vehicles, resulting in complex vehicle layout and assembly operations, and poor coordination. It is often manifested in that it takes up a lot of space, it is difficult to arrange and maintain, and the coordination relationship of the vehicle driving s...

The layout of other structures is usually based on the type and use of different vehicles, and is set around the drive structure; resulting in suspension, vehicle frame and electric motors. The coordination of the driving device is not stable, especially for special vehicles such as multi-axle vehicles, it cannot meet the generalization and modularization requirements of multi-axle electric drive vehicles, resulting in complex layout and assembly operations of vehicles and poor coordination

It is often manifested in that it takes up a lot of space, it is difficult to arrange and maintain, and the coordination relationship of the vehicle driving system is poor.
