Embodiment Construction

[0038] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0039] This embodiment provides an unmanned vehicle chassis integrated with four-wheel hub motors and integrated brakes and steering, which can solve the problems of complex mechanical structure and insufficient power of the existing unmanned vehicle chassis system.

[0040] Such as figure 1 As shown, the chassis system of the four-wheel unmanned vehicle includes: a frame body system, four wheels 103, and a driving system, a steering system, a braking system and a suspension system for each wheel. The vehicle frame 101 is made of aluminum profile, and its exterior is surrounded by a vehicle body 102 . The hollow part inside the body can be used to place the power system and control system of the unmanned vehicle, and other mechanical equipment and electronic equipment can be added to the frame 101 and the body 102 to modify the unmanned vehicle to achieve...

Abstract

The invention provides an array type hub motor driving system and a multi-wheel hub motor integration and brake steering integrated unmanned vehicle chassis. The problems that an existing unmanned vehicle chassis system is complex in mechanical structure and insufficient in power can be solved. The multi-wheel hub motor integration and brake steering integrated unmanned vehicle chassis comprises avehicle body frame system and more than two wheels, and each wheel is correspondingly provided with a set of driving system, a set of steering system, a set of braking system and a set of suspensionsystem; the driving system adopts an array type hub motor to drive a corresponding wheel; the wheel is directly driven to rotate by adopting the array type hub motor, compared with a middle-arranged motor, the transmission mechanism is simple and easy to maintain, and compared with a traditional hub motor, the driving force is stronger. The steering system directly drives the wheels correspondingto the steering engine to rotate around the steering main pin by adopting the steering engine so as to realize steering; the brakingsystem adopts a hydraulic station to control a caliper brake to provide brake torque for a corresponding wheel; and each wheel is connected with the vehicle body frame system through a set of suspension system.

Description

technical field [0001] The invention relates to an unmanned vehicle chassis, in particular to a four-wheel unmanned vehicle chassis, which belongs to the technical field of unmanned vehicles. Background technique [0002] Compared with traditional vehicles, unmanned vehicles can output a variety of control signals, and the existing unmanned vehicle chassis systems often rely on the transformation of manned vehicle chassis systems, and their shortcomings are summarized as follows: [0003] (1) There are mainly two transmission methods used. One is to use the mid-mounted motor as the power source, and the power is output to the wheels through a mechanical transmission and reduction mechanism. This method has long transmission paths, low efficiency, and high manufacturing costs; the second is Driven by hub motors, this method has disadvantages such as small torque and low speed. [0004] (2) The steering mechanism mostly adopts the mechanical linkage type, which is complex to ...
