The linkages 10 are for pivotally securing the upper supports 11 together, pivotally securing the lower supports 12 together, and pivotally fastening each coupling member 13 between the upper support 11 and the lower support 12 at the same side together. The suspension also includes an elongated shock absorber 2 having both ends secured the upper supports 11 via brackets 111.

Description

SUSPENSION FOR A TRICYCLE
BACKGROUND OF THE INVENTION
1. Field of Invention
The invention relates to suspensions and more particularly to a suspension for use on two front/rear wheels of a tricycle.
2. Description of Related Art
Suspension for vehicles is known in the art. Moreover, a great number of published documents are known. For example, there is a suspension arrangement for road vehicles. The frame of the vehicle has a pair of pivots displaced from each other, carrying levers, the opposite ends of which are attached to an axle of a wheel, the displacement of the levers about their pivots being restrained to a desired degree by means of springs or the like.
Further, there is a wheel suspension for motor vehicles. It includes a wheel carrier supporting the wheel. Of the wheel guide members, one guide member is displaceable approximately in the transverse direction of the vehicle by way of an adjusting motor and supports the support spring. With its inner end, this guide member is pivotally connected at an intermediate lever. This intermediate lever is pivotally supported at the vehicle body about a pivot axis extending approximately in the vehicle longitudinal direction and is connected at its lower end with the adjusting motor by way of lateral tie rods.
Furthermore, there is an elastic suspension for vehicular automobiles separately suspended.
But the conventional suspension for vehicles including tricycles is complex in structure, expensive to manufacture, and difficult of maintaining.
The invention can eliminate disadvantages of the prior suspensions and provide further advantages.
SUMMARY OF THE INVENTION
It is therefore one object of the invention to provide a suspension for use on two front/rear wheels of a tricycle comprising a linking assembly comprising two H-shaped lower supports, two H-shaped upper supports, two coupling members each secured to a hub of the front/rear wheel, and a plurality of internally threaded linkages for pivotably securing the upper supports together, pivotably securing the lower supports together, and pivotably fastening each coupling member between the upper support and the lower support at the same side together; and elongated shock absorbing means having both ends secured the upper supports.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of a suspension for a tricycle according to the invention; FIG. 2 is an exploded view of FIG. 1; FIG. 3 is a perspective view of the suspension mounted on two front/rear wheels (only one wheel is shown) of a tricycle; FIG. 4 is a view similar to FIG. 3 where the tricycle is wheeling in a stable state; FIG. 5 is a view similar to FIG. 4 where both the front/rear wheels are tilting (only one wheel is shown) when wheeling through a curve of road; and FIG. 6 is a view similar to FIG. 4 where the other front/rear wheel (not shown) is encountered a raised area of the road.
DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 to 3, a suspension for use on two front/rear wheels 5 of a tricycle 4 in accordance with the invention comprises the following components as discussed in detail below.
A linking assembly 1 comprises a plurality of internally threaded linkages 10, two H-shaped upper supports 11, two H-shaped lower supports 12, and two coupling members 13. Each of the upper supports 11 has a through hole 110 at one of four ends. Each of lower supports 12 has a through hole 120 at one of four ends. A bearing 14 is provided in each through hole 110 or 120. A concave mounting member 111 having a threaded hole 112 is provided on top of the interconnecting part of each upper support 11. Each coupling member 13 having a projecting stepped-outer diameter hollow coupling 131 and four projections arranged as four corners of a rectangle, each projection having a through hole 130.
In assembly, each of two threaded fasteners (e.g., bolt and nut combinations) 15 is used to drive through either end of a spring loaded shock absorber 2 and the threaded hole 112 to secure the shock absorber 2 and the upper support 11 together.
A linkage 10 loosely passes through a bearing 14, one through hole 110 of one upper support 11, one through hole 110 of the other upper support 11, another through hole 110 of one upper support 11, and one through hole 110 of the other upper support 11 into another bearing 14 to have one end disposed in one through hole 110 of one upper support 11 and the other end disposed in one through hole 110 of the other upper support 11 respectively. A threaded fastener 15 is driven into one end of the upper support 11 and another threaded fastener 15 is driven into the other end of the upper support 11 at the same side. Thus, two upper supports 11 are pivotably secured together. Likewise, the two lower supports 12 can be pivotably secured together.
Another linkage 10 loosely passes through a bearing 14, one through hole 110 of one upper support 11, one through hole 110 of the coupling member 13, another through hole 110 of the coupling member 13, and another through hole 110 of one upper support 11 into another bearing 14 to have one end disposed in one through hole 110 of one upper support 11 and the other end disposed in one through hole 110 of one upper support 11 respectively. A threaded fastener 15 is driven into one end of the upper support 11 and another threaded fastener 15 is driven into the other end of the upper support 11 at the same side. Thus, one upper support 11 and the coupling member 13 are pivotably secured together. Likewise, each of the two coupling members 13 can be pivotably secured between the upper support 11 and the lower support 12 at the same side. Moreover, the coupling 131 of either coupling member 13 can be secured to a hub 3 of a wheel 5 by means of a bearing 4. As an end, the invention is assembled.
Referring to FIG. 4, the tricycle is wheeling in a stable state. That is, no irregularities are encountered. A substantially rectangle can be seen from a front/rear end of the suspension.
Referring to FIG. 5, it is shown that two front/rear wheels 5 are tilting (only one wheel 5 is shown) when wheeling through a curve of road. Moreover, the suspension is tilted toward one wheel 5 to shape as a parallelogram. This has the benefit of preventing the vehicle from tipping over when passing a curve of road.
Referring to FIG. 6, the other wheel (not shown) is encountered a raised area of the road. The left portion of the suspension is substantially not affected and the right portion thereof is pivotably lifted a short distance with the shock absorber 2 being compressed. Therefore, the force of shocks and jarring is substantially absorbed by the shock absorber 2. This can minimize discomfort when such irregularities encountered.
While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
