Abstract

A wheel spliced by three idler wheels is combined by a wheel shaft, a rolling body and an external support, wherein sliding friction is transformed into rolling friction by rolling of a round wheel relative to a rolling surface, the complete wheel is spliced by the three idler wheels, any two of the idler wheels are connected by a pulling and pressing spring for damping, the three idler wheels are distributed in an equilateral triangle for external profile, a side support can be rotated around a main shaft under pulling and pressing by the spring with pressure changes in order to decrease impacts brought by vibration, and the wheel can move forwards smoothly on an uneven pavement with a relatively big obstacle and can decrease the mechanical vibration caused by the concave-convex rolling surface.

Description

A kind of wheel by three roller splicings
Affiliated technical field
The utility model relates to a kind of tourelle, by outline, becomes three trundle splicings that equilateral triangle distributes to form, and connects damping arbitrarily between two-wheeled by drawing-pressing spring.
Background technology
Current 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 what traditional wheel cannot be done is greatly easily blocked by surface protuberances very much, cannot 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
In order to overcome existing wheel, cannot cross preferably protruding obstacle and the larger deficiency of vibrations, the utility model provides a kind of wheel by three roller splicings, the mechanical shock that this wheel brings when can not only effectively cross larger obstacle and can reduce to roll.
The utility model solves the technical scheme that its technical matters adopts:
By a wheel for three roller splicings, in trundle, batter support, roller, axle, drawing-pressing spring, main shaft form, and described trundle is three, is installed on respectively on three batter supports, between any two rollers, by drawing-pressing spring, connects damping.Described three trundle outlines become equilateral triangle to distribute, and batter support connects via main shaft, can under pressure-dependent drawing-pressing spring tension and compression effect, around main shaft, rotate.Two coupling ends of described batter support are circular: between two coupling ends of batter support, by the circular arc circumscribed with two circles, be connected.Drawing-pressing spring between described two-wheeled is normality while being stressed, under tension and compression condition, all elastic deformation can occur, be parallel to sliding surface in extended state, side is compressive state.Trundle is connected with bearing transition fit with batter support axle in roller, and one end that does not connect trundle of three batter supports is connected by connecting gap of main reinforcement.
The beneficial effects of the utility model are, can have on the road surface of larger encumbrance smooth and easy forward direction and can reduce the concavo-convex mechanical shock bringing due to rolling surface in unfairness.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is assembly drawing of the present utility model
In figure, in 101. trundle 102. batter support 103. rollers, axle 104. drawing-pressing spring 105. main shafts 106. can rotate 107.120 degree 108. wheel bearing 109. main bearings by a small margin.
The specific embodiment
In Fig. 1, a kind of wheel by three roller splicings, in trundle 101, batter support 102, roller, axle 103, drawing-pressing spring 104, main shaft 105 form, described trundle 101 is three, be installed on respectively on three batter supports 102, between any two trundles 101, by drawing-pressing spring 104, connect damping, batter support 102 is connected by axle in roller 103 with trundle 101, between its axis and wheel, there is wheel bearing 108 to be connected, 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, assembling effect can be rotated and be advisable by a small margin around three main shafts 105 with three batter supports 102, drawing-pressing spring 104 is connected between any two batter supports 102, arbitrarily between two axles, angle is 120 degree, and can slightly rotate around main bearing 109 during batter support force.
