Embodiment 1

[0044] Such as figure 1 As shown, when the rudder wheel drive vehicle is driving the vehicle alone, the mecanum wheel 12 supports the movement of the vehicle body. Since the mecanum wheel 12 can realize accurate omnidirectional movement without turning the wheel, the driving vehicle and the vehicle can be quickly realized. Docking of transported equipment. At this time, the steering wheel positioned at the center of the driving car body is out of contact with the ground under the action of the spring.

[0045]The rudder wheel drive vehicle includes an upper baffle 2 and a lower baffle 3 which are arranged on the vehicle body and are fixedly connected with the vehicle body. A movable middle baffle 4 is arranged between the upper baffle 2 and the lower baffle 3. The middle baffle shown in the figure 4 and the upper baffle 2 are connected as a whole through the sealed first air bag 5, and the middle baffle 4 and the lower baffle 3 are connected as a whole through a spring 6. Und...

Abstract

The invention discloses a combined traction system composed of a plurality of steering wheel driving vehicles and a control method. The traction system includes a transfer section and several steering wheel driving vehicles connected with the transfer section. The steering wheel driving vehicle is composed of a mecanum wheel and a steering wheel. The air cushion driving car combination method, multiple driving cars and the transfer section are docked and combined to realize the forward, backward, oblique and steering of the transfer section, and the maximum traction control of the driver is realized by controlling the contact force between the steering wheel and the ground. The lifting and lowering of the car mechanism realizes the omnidirectional rotation of the equipment, so as to realize the precise joint control of the equipment. The lifting steering wheel in the present invention does not contact the ground when turning, which reduces the wear of the lifting steering wheel and improves the service life of the lifting steering wheel; the steering accuracy is not affected by the quality of the ground, so the maneuverability of the steering angle is strong, and the precise operation of the equipment is realized .

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a combined traction system composed of a plurality of rudder wheel driven vehicles and a control method during a wind tunnel test. Background technique [0002] With the development of modern industry, the mobile transportation and assembly of large and complex equipment put forward higher requirements for the driving vehicle of air cushion transportation technology. The transportation and assembly of large equipment has the characteristics of complex structure, heavy weight and high assembly precision. In order to meet the driving force requirements of large-scale equipment air cushion transportation, traditional driving vehicles often increase the friction between the driver and the ground by increasing the weight of the driving vehicle itself or carrying additional loads to increase the driving force of the driving vehicle. However, as the weight of the driving vehicle increa...
