Abstract

The invention discloses a wheel spliced by three rollers. The wheel is formed by combining an axle, a rolling body and an external bracket, wherein sliding friction is converted into rolling friction by means of the rolling of a round wheel relative to a rolling surface. The whole wheel is formed by splicing the three small rollers; each two rollers are connected through a tension compression spring for damping; the outlines of the three rollers are distributed in a equilateral triangle; and a side bracket can rotate around a spindle along with pressure change under the tension and compression of the spring, so that the impact brought by vibration is reduced, the wheel can smoothly move forward on an uneven pavement with large obstacles, and mechanical shock brought by the concave-convex rolling surface can be alleviated.

Description

A kind of wheel by three roller splicings
Affiliated technical field
The present invention relates to a kind of tourelle, become three trundle splicings that equilateral triangle distributes to form by outline, connect damping by drawing-pressing spring between two-wheeled arbitrarily.
Background technology
Present known wheel is by wheel shaft, single rolling body, and outside support combines, and relies on the rolling of the relative rolling surface of circle wheel that cliding friction is converted into friction of rolling, thereby reduces power consumption.But traditional wheel can't be done is easily blocked by surface protuberances very greatly, can't smooth and easy rolling advance.The larger generation noise of vibrations does not damage corollary apparatus simultaneously owing to having shock absorption device to cause to roll on uneven earth's surface.
Summary of the invention
Can't cross preferably protruding obstacle and the larger deficiency of vibrations in order to overcome existing wheel, the invention provides a kind of wheel by three rollers splicings, the mechanical shock that this wheel can not only effectively be crossed larger obstacle and bring can reduce to roll the time.
the technical solution adopted for the present invention to solve the technical problems is: a kind of wheel by three roller splicings, by wheel shaft, rolling body, outside support combines, rely on the rolling of the relative rolling surface of circle wheel that cliding friction is converted into friction of rolling, the whole wheel by three trundle splicings forms, connect damping by drawing-pressing spring between two-wheeled arbitrarily, three roller outlines become equilateral triangle to distribute, side stand is connected to change with pressure via gap of main reinforcement and rotates around main shaft under spring tension and compression effect, thereby reduce to shake the impact that brings, two coupling ends of foot support plate are circular, between by being connected with the two circumscribed arc transition of circle, steamboat is connected with the bearing transition fit with batter support axle in roller, the not connection steamboat end of three foot supports is connected by connecting gap of main reinforcement, it is normality when the spring between two-wheeled does not stress, elastic deformation (the extended state that is in that is parallel to sliding surface all can occur under the tension and compression condition, side is compressive state), steamboat is connected with the bearing transition fit with batter support axle in roller, the not connection steamboat end of three foot supports is connected by connecting gap of main reinforcement.
The invention has the beneficial effects as follows, unfairness has smooth and easy forward direction on the road surface of larger encumbrance and can reduce the concavo-convex mechanical shock that brings due to rolling surface again.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is assembly drawing of the present invention
In figure, interior axle 104. drawing-pressing spring 105. main shafts 106. of 101. trundle 102. batter support 103. rollers can rotate 107.120 degree 108. wheel bearing 109. main bearings by a small margin
The specific embodiment
In Fig. 1, batter support 102 is connected by axle in roller 103 with trundle 101, has wheel bearing 108 to be connected between its axis and wheel, the interior axle 103 transition fit outer rings of bearing inner ring and roller and trundle 101 transition fit.The other end of three batter supports that connect is linked together through main shaft 105 and main bearing 109 transition fit, the assembling effect can be rotated by a small margin around three main shafts 105 with three batter supports 102 and is advisable, drawing-pressing spring 104*3 is connected between any two side stands 102, arbitrarily between two axles, angle is 120 degree, and can slightly rotate around main bearing 109 during the batter support force.
