Abstract

The invention relates to a multimode steering mechanism, which comprises a worm and gear subassembly, a speed reducer and a motor, wherein the worm and gear subassembly is mounted on the bottom surface of a car frame supporting part; the speed reducer is mounted on a car frame or the worm and gear subassembly; the motor is mounted on the car frame or the speed reducer; an input shaft of the worm and gear subassembly is connected with an output shaft of the speed reducer; an input shaft of the speed reducer is connected with an output shaft of the motor; the worm and gear subassembly is provided with a steering sensor device which comprises a stop lever, a driving lever and a sensor; one end part of the stop lever is fixed on the bottom surface of the car frame supporting part; the other end part of the stop lever extends towards one side of the sensor; the lower part of the driving lever is fixed on an output shaft of the sensor; furthermore, the output shaft of the sensor can rotate along the self axial lead of the output shaft; and the upper part of the driving lever can be in sliding contact with the length direction of the other end part of the stop lever. The multimode steering mechanism has high steering precision, and is flexible to steer and convenient to repair, and the steering mechanism adopts a worm and gear structure, has a large steering angle, and is particularly applicable to a vehicle needing multimode steering.

Description

technical field [0001] The invention relates to a multi-mode steering mechanism. Background technique [0002] The multi-mode steering system is an important part of the walking and operating system of large engineering vehicles and engineering machinery driven by multiple axles. This type of vehicle, often due to the large body size, requires a distributed arrangement of multiple drive and control mechanisms from the perspectives of driving, manipulation and control, and structural layout. The steering system needs to be implemented on the site according to the needs of complex tasks Row, horizontal, vertical figure-of-eight steering (that is, three steerings including front eight, rear eight and symmetrical eight), center steering and other steering modes. [0003] Wherein: the existing steering mechanism has the disadvantages of small steering angle, no sensor, inaccurate steering angle, etc., which is not suitable for the use of multi-mode steering systems.
