Definitions

  • the present invention relates to the structure of a universal wheel, in particular to a universal wheel capable of moving in any direction. Background technique
  • Traditional swivel wheels can only move forward or backward in the direction of the wheel. If you do not turn the wheel, you cannot move the wheel laterally or diagonally. Therefore, it can only be used as a passive wheel.
  • the wheels of a conventional universal wheel must be turned to the same direction as the external force before they can be dragged by the external force to move along the direction of the external force. Although it can move in any direction, if the direction of the external force is different from the direction of the wheel when starting or when the external force changes the direction of movement, the traditional universal wheel requires a period of wheel steering. In this way, there will be wobbles during use and it is not flexible enough.
  • the direction of the load of the traditional universal wheel is a distance from the center of the wheel. In this way, the wheel frame of the traditional universal wheel receives a large eccentric moment, which affects the service life of the wheel frame.
  • its design has proved that there are still some shortcomings in practice: due to the large gap in the outer arc of the wheel composed of large and small drum rollers, there are problems such as sounds during movement.
  • the present invention provides a universal wheel that can be used as a driving wheel or a passive wheel.
  • the technical solution adopted by the present invention to solve its technical problem is: There is a half-wheel hub, and a groove is provided in the middle of the half-wheel hub. A Y-shaped bracket is inserted into the groove, and the left and right fork heads have shafts above the Y-shaped bracket. A mandrel can be installed in the hole, and a small waist drum roller can be installed on the mandrel. There are shaft holes on the left and right sides of the middle of the Y-shaped bracket to install a short mandrel. A large waist drum roller can be installed on the short mandrel.
  • the left and right fork heads above the bracket are buried in the grooves of the large waist drum roller, and the arc base under the Y-shaped bracket is inserted into the half hub; the large waist drum roller and the small waist drum roller are alternately distributed on the entire rim of the wheel :
  • Rolling bearings are mounted on the outer ends of the two half-wheel hubs, with a center shaft in series.
  • the large and small waist-shaped rollers are formed into an outer contour and are arranged between arcs on the outer circle.
  • the gap is l-2mm; the Y-shaped bracket is hidden in the wheel hub; the number of large and small drum rollers is equal, and the number of large and small drum rollers is 3-50 Correct.
  • the beneficial effect of the present invention is that, since the conventional universal wheel must leave space for the wheel to rotate around the vertical axis, the universal wheel of the present invention does not need to leave space, so the structural space is saved.
  • the invention when it is used as a passive wheel, when it is subjected to external forces in different directions, it immediately moves in the direction of the external force. Do not turn the wheel, because the universal wheel has large and small waist-shaped rollers that have two freedoms in contact with the ground. The degree of movement (that is, the free rotation of the large and small drum rollers and the free rotation of the wheels) greatly improves the flexibility of the universal wheel.
  • the direction of the universal wheel bearing load of the present invention is through the center of the wheel, so there is no eccentric moment, and the force on the wheel frame is good.
  • the invention overcomes the shortcomings of the original patent application (02234912. X), realizes the work continuity of arranging the outlines into an outer circle, and eliminates the problem of sound in the original patent application. Therefore, the present invention can achieve the intended purpose.

Abstract

L'invention concerne une roulette comprenant un enjoliveur muni d'une rainure dans laquelle est insérée une patte de fixation en Y. Un mandrin équipé de petits galets en forme de tambour est installé dans l'alésage du crochet de la patte de fixation. Un mandrin court équipé de grands galets en forme de tambour est monté dans la patte de fixation. Au sommet de la patte de fixation, des crochets sont installés dans les rainures des grands galets en forme de tambour. En même temps, des supports arqués placés sous la patte de fixation en Y sont insérés dans l'enjoliveur. Des roulements à galet munis d'un arbre sont montés entre les enjoliveurs. La disposition alternée des petits et des grands galets en forme de tambour forme la bordure et un vide de 1 à 2 mm sépare les arcs. De plus, les pattes de fixation en Y sont cachées dans l'enjoliveur, et on compte 3 à 50 paires de petits et de grands galets en forme de tambour.
