Technical scheme of the present invention is further described below in conjunction with accompanying drawing:
As shown in Figure 1 (a) and Fig 1 (b) shows, the omni-directional wheel adopted is double wheel, each single wheel is made up of along the son wheel of taking turns circumferentially some S. A.s, two single-wheels are staggered the angle of distribution of a son wheel mutually, therefore observe from the side of omni-directional wheel, what two row's wheels were formed is a complete circle wheel.Therefore, this omni-directional wheel both can rotate around wheel shaft, also can by son wheel rotation and produce along wheel shaft to transverse shifting.Motion these the two kinds combinations of moving often of wheel, can carry out roller displacement along plane either side.
As shown in Figure 2, this omni-directional wheel can replace the cardan wheel in conventional stroller, and the rotating shaft of omni-directional wheel does not need to be controlled by steering swivel system, is in stationary state for car body.When perambulator be pushed do straight-line motion forward or backward time, three wheels normally roll separately, when perambulator is applied in moment of torsion by handlebar, rearmounted two symmetrical fixing arbor wheels do differential motion, to coordinate car body to turn to, preposition omni-directional wheel, can also transverse shifting because can roll forwards, backwards, therefore, car body also can be coordinated to turn to.Change rotating direction because omni-directional wheel does not resemble cardan wheel by eccentric throw, and its rotating shaft is fixing relative to car body.Therefore, when moving, not having the violent dancing that cardan wheel produces when being subject to the random uneven friction force in ground, would not produce swinging of the car body produced by this swing yet.Adopt the perambulator of omni-directional wheel more steady when moving.When car body is in static state, the cardan wheel of tradition cardan wheel preposition toy tricycle is due to the existence of random eccentric moment, the direction of its deflection is uncertain, likely there is deflection state as shown in Figure 3, outside the triangle area that side test force point of action 8 will not be formed at three wheel touchdown points, although or in triangle, this point is also very near leg-of-mutton sideline.When the handlebar of vehicle frame (1) is subject to thrust forward or backward, each wheel is pushed, thus car body can move forwards, backwards.When handlebar left and right stressed not identical and produce moment of torsion time, preposition omni-directional wheel (2) son wheel start rotate, rearmounted fixing arbor wheel (3) does differential motion, thus car body can be rotated freely.The S. A. of preposition omni-directional wheel (2) is fixed form, thus the yaw phenomenon of advancing eliminating the preposition cardan wheel of employing and cause, during use, when the handlebar of vehicle frame (1) is subject to thrust forward or backward, each wheel being pushed, thus car body can move forwards, backwards.When handlebar left and right stressed not identical and produce moment of torsion time, preposition omni-directional wheel (2) son wheel start rotate, rearmounted fixing arbor wheel (3) does differential motion, thus car body can be rotated freely.The S. A. of preposition omni-directional wheel (2) is fixed form, thus the yaw phenomenon of advancing eliminating the preposition cardan wheel of employing and cause, add the dynamic stability of car body and static resistant to tipping.
