Embodiment 1
[0047] Such as figure 1As 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.
[0048] 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...

The invention discloses a combined traction system composed of multiple steering wheel driving vehicles and a control method. The traction system comprises a transfer section and a plurality of steering wheel driving vehicles connected with the transfer section, and the steering wheel driving vehicles are in an air cushion driving vehicle combination mode that Mecanum wheels and steering wheels are combined. Multiple driving vehicles and a transfer section are in butt joint and combined to achieve forward movement, backward movement, oblique movement and steering of the transfer section, maximum traction control of a driver is achieved by controlling contact force of a steering wheel and the ground, in-situ omni-directional rotation of equipment is achieved by controlling lifting cooperation of the steering wheel and a parking mechanism, and therefore precise combined control over the equipment is achieved. An elevator wheel does not make contact with the ground during steering, abrasion of the elevator wheel is reduced, and the service life of the elevator wheel is prolonged; the steering precision is not influenced by the ground quality, so that the operability of the steering angle is high, and the precise operation of 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...
