Problems solved by technology

[0004] However, the high-speed crawler-type action system of Ackermann steering has the disadvantages of too large turning radius and poor maneuverability in a small space at low speed, and in the case of soft soil roads, the use of speed differential steering will not bring great wear and tear to the crawler belt. , differential steering is more applicable

Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] The purpose of the present invention is to provide a high-speed crawler-type action system with Ackermann-active differential steering, which has three steering modes, namely pure Ackermann steering, pure differential steering and Ackerman-active differential steering. Compound steering, with independent control functions of Ackerman steering and differential steering, not only can realize Ackerman steering similar to wheeled vehicles by making the two c...

Abstract

The invention relates to a high-speed crawler-type action system for Ackermann-active speed difference compound steering, which belongs to the field of vehicle parts and has three steering modes, namely pure Ackerman steering, pure speed difference steering and Ackerman- The active speed differential compound steering can be selected according to the actual situation; it has two steering modes, which can not only realize the Ackermann steering similar to wheeled vehicles by making the two crawler belts rotate relative to the car body at different angles, but also can Through the speed difference of the crawlers on both sides, the speed difference steering and body attitude control are realized; when any steering method fails to work normally, the other steering method can continue to drive in an emergency state and maintain a certain steering ability, ensuring Driving safety in extreme conditions.

Description

technical field [0001] The invention relates to the technical field of vehicle parts, in particular to a high-speed crawler-type action system with Ackermann-active differential compound steering. Background technique [0002] The traditional crawler-type action system uses the speed difference between the two sides of the crawler to realize the steering, which is characterized by a small turning radius and high power consumption; the power consumption gap between the inner and outer crawlers is large when the speed difference is turned, and a complex power transfer device is required to achieve inner and outer rotation. The redistribution of the power flow of the crawler leads to a large difference in motor power requirements for direct driving and steering. If the drive motor is designed according to the power requirements of direct driving, the power of the outer motor is insufficient when turning. If the motor is designed according to the power requirements of steering ,...
