Suspension steering mechanism based on four-wheel drive platform car

Abstract

The invention relates to a suspension steering mechanism based on a four-wheel drive platform car. The mechanism comprises a vehicle body platform, a steering mechanism and a damping suspension mechanism, the steering mechanism is arranged in the middle of the body platform; damping suspension mechanisms are arranged on the two sides of the vehicle body platform, the steering mechanism comprises asteering motor, a connecting rod assembly and four pull rod assemblies, the four pull rod assemblies are driven by the steering motor to move, the steering motor transmits torque through the connecting rod assembly, and the pull rod assemblies are connected with the damping suspension mechanisms in a one-to-one correspondence mode. The steering mechanism is additionally arranged to achieve pivotsteering action, the operation requirement of a narrow space working environment can be met, the damping suspension mechanism is arranged to achieve damping and buffering, tire abrasion is reduced, and the operation requirement of a bumpy road surface can be met.

Description

technical field [0001] The invention relates to a suspension steering mechanism based on a four-wheel drive platform vehicle. Background technique [0002] Existing four-wheel-drive platform vehicles are mainly used in fields such as power industry inspections and logistics intelligent handling. Most of their structures are directly driven by four-wheel motors and rely on the differential speed of the drive motors to achieve steering. On the one hand, there is a turning radius, which is difficult to apply to The working environment with a narrow space and lack of shock absorption and buffering on the other hand make the tires often in a state of sliding friction when turning, which can easily lead to serious tire wear on the ground with harsh working environments, which not only affects the performance of the four-wheel drive platform vehicle, but also In addition, in the case of uneven ground, since the four-wheel drive platform vehicle does not have a shock absorption syst...

On the one hand, there is a turning radius, which is difficult to apply to The working environment with a narrow space and lack of shock absorption and buffering on the other hand make the tires often in a state of sliding friction when turning, which can easily lead to serious tire wear on the ground with harsh working environments, which not only affects the performance of the four-wheel drive platform vehicle, but also In addition, in the case of uneven ground, since the four-wheel drive platform vehicle does not have a shock absorption system, it is likely to cause one of the wheels to hang in the air, causing the motor encoder to calculate the mileage incorrectly.
