Abstract

The invention discloses a distributed driving vehicle chassis. The chassis comprises four hub motor driving brake assemblies, a front auxiliary frame assembly, a rear auxiliary frame assembly and a frame assembly, wherein the front auxiliary frame assembly and the rear auxiliary frame assembly are respectively assembled on front and back of the frame assembly, two hub motor driving brake assemblies are respectively assembled on two sides of the front auxiliary frame assembly, and the rest two hub motor driving brake assemblies are respectively assembled on two sides of the rear auxiliary frameassembly. The chassis has the beneficial effects that a whole vehicle controller is adopted and is used for receiving a sensor signal and a vehicle CAN bus signal, the whole vehicle controller further calculates and decides to obtain a target control signal, the whole vehicle controller sends the target control signal to a vehicle CAN bus, and the target control signal is received by other controllers, so that an actuator is further controlled; and two storage batteries are adopted and are used for supplying power for the controllers of the vehicle, the two storage batteries are a front vehicle-mounted 24V battery and a rear vehicle-mounted 24V battery, and the situation that the vehicle loses control caused by failure of storage batteries or the power supply line is effectively avoided.

Description

technical field [0001] The invention relates to a vehicle chassis, in particular to a distributed drive vehicle chassis. Background technique [0002] At present, with the increasingly serious environmental pollution, the pollution problems caused by traditional fuel vehicles cannot be ignored, and new energy vehicles are in the process of rapid development. For electric vehicles in new energy vehicles, according to the different drive schemes of electric vehicles, they can be divided into single-axis drive electric vehicles, dual-axis drive electric vehicles and distributed drive electric vehicles. Distributed drive electric vehicle means that the driving motor of the car is integrated into the four wheels of the car, and the four hub motors drive the wheels to rotate respectively to drive the vehicle. Such a driving scheme will save the transmission devices such as the shifting mechanism, deceleration mechanism, differential mechanism and transmission shaft of the vehicle...
