CN201626493U - Double bracket of two-wheeled vehicle - Google Patents

Abstract

The utility model relates to double bracket of a two-wheeled vehicle. The double bracket can support the two-wheeled vehicle, wherein one wheel can be hung in the air; and the double bracket is positioned at the front part of a rear wheel. The double bracket mainly comprises a main body, a base, a tension spring and locating shafts, wherein the tension spring is arranged in the middle of the base; the left end and the right end of the base are articulated with the upper end of the main body by the two coaxial-line locating shafts; the front parts of the left end and the right end of the base are provided with parking limit platforms, and the rear parts thereof are provided with retracting limit platforms; the tension spring is hung in a locating ring that is arranged in the middle parts of the base and the main body; the two ends of the locating ring are closed; a left main body support leg and a right main body support leg are symmetrically arranged; the axes of the support legs are in the S shape consisting of double arcs and a straight line; and a concave-down arc upper cross brace and an up-warped arc lower cross brace are arranged between the left main body support leg and the right main body support leg. The height of the base of bracket can be smaller, the distance between the two support legs of the bracket can be longer, and the locating shafts are fixed by a locating hole, a locating nut and a locknut on the base; therefore, except for a foot bar, the overall bracket has symmetrical and smooth appearance.

Description

Double bracket in the two-wheel car

Technical field

The utility model relates to a kind of two-wheel car can being propped, and makes 1 liftoff unsettled halting mechanism of wheel, especially is positioned at the trailing wheel front portion, has symmetry two rotating shafts, extension springs to be positioned at the car double bracket of car longitudinal plane of symmetry.

Background technology

At present, known two-wheel car cantilever type is more, and double bracket, single-side stand, medium-height trestle, side stand are arranged.Single-side stand, side stand, single medium-height trestle are easy to use, but the Parking aftercarriage tilts, and easily move backward when car deadweight and load-carrying are big.Back double bracket uses now more, but needs the car rear portion is mentioned during Parking, uses inconveniently, and it is bigger to conduct oneself with dignity.The present middle double bracket that uses, the rotating shaft in top, extension spring is positioned at side, causes that both sides unbalance stress, profile are not good, existence obviously exposes protrusion, extension spring easily comes off, and commonality is low.Double bracket two footing distances is too little in some car, when ground inadequately at ordinary times or wind easily move backward when big.Double bracket and bottom of frame bonded assembly substructure height are very big in some, when bottom of frame and ground are nearer, and can not normal use.

Summary of the invention

In order to overcome the deficiency of existing support, the utility model provides a kind of support, and this support Parking is stable, easy to use, safe in utilization, extension spring does not come off, main body profile symmetry, smoothness, the commonality height.

The technical scheme that its technical matters that solves the utility model adopts is: support is mainly by main body, base, extension spring, fix shaft four component set-ups, and extension spring is placed on the base middle part, and two ends, the base left and right sides are hinged by two coaxial line fix shafts and main body upper end.

The aforementioned body parts are made up of steady ring, upward stull, lower brace, treadle, treadle cover, foot pad, treadle cover fixing screw nut under supporting leg, supporting leg seat, the extension spring.Main body can adopt combinations such as blanked part, tubing, section bar, gauge member, plastic and welding to make, and also can adopt methods integral body such as casting, die forging to make.Main body is up-narrow and down-wide.About supporting leg each one, left-right symmetric, the supporting leg axis is by two circular arcs and rectilinear(-al) S type, the spherical foot pad of supporting leg lower end socket, two supporting leg seats are symmetrical set, the supporting leg seat has two vertical locating plate faces, be connected with the supporting leg upper end below, there is the rotating shaft knock hole that matches with fix shaft the side, and last stull is recessed circular arc, lower brace is arch circular arc, the two ends of last lower support are connected with left and right sides supporting leg, and steady ring places the middle part of stull under the extension spring, and the following rear of left branch leg is connected with treadle, the treadle cover is arranged at treadle top, and both are located by screw-nut.

Above-mentioned base member is made up of steady ring in underframe, setscrew nut, the extension spring.Base can adopt Combination Welding manufacturings such as blanked part, section bar, gauge member, also can adopt the whole manufacturing of methods such as casting, die forging.Two ends, the underframe left and right sides are rotating shaft locatings plate of symmetry, and the rotating shaft knock hole is arranged on the rotating shaft locating plate, and the plate inner face has setscrew nut, knock hole is coaxial with tapped bore, rotating shaft locating plate front end has the parking limit dais, and limit dais is packed up in the underframe rear end, and steady ring in the extension spring is arranged at the bottom.

Above-mentioned fix shaft parts are made up of screw axis, black nut, neonychium, and fix shaft is fixing altogether by the knock hole on the base, setscrew nut and black nut.

Base top can with the bottom of frame direct connection, also can connect both by height adjustment spare.

The base two ends connect by 2 fix shafts and main body, and the extension spring two ends hang on the steady ring, and main body is rotated along the fix shaft center with respect to base, can and pack up two spacing places of a limit dais due to the parking limit dais on the base.When the parking stall, the extension spring axis is positioned at the front portion at fix shaft center, and the component that this state tension spring tension produces makes supporting leg rely on the parking limit dais.When packing up, the extension spring axis is positioned at the top at fix shaft center, and the component that this state tension spring tension produces relies on supporting leg and packs up limit dais.Between screw axis end face and the supporting leg seat lateral surface, between supporting leg seat medial surface and the underframe rotating shaft locating plate outside, neonychium is arranged.Black nut is turned round in screw axis the inner, increases the screw axis rigidity, prevents that screw axis is loosening.

The beneficial effects of the utility model are, during parking, pin is trampled bar (cover), the supporting leg foot pad is contacted with ground, and then pull a cart backward, this moment is according to the size of support and angle, according to decomposition of force and composition principle, generation be the pulling force several times to raising force, car is propped naturally come to a complete stop, supporting leg relies on the parking limit dais.The go-cart forward on the parking stall, car falls naturally, and supporting leg relies on packs up limit dais.It is bigger that support two footing distances can be made, when the car deadweight and load-carrying is big, ground is flat inadequately, also be difficult for reversing when wind is big.The bracket base upper surface can produce suitable length and wide, and support can be connected with vehicle frame is convenient by multiple modes such as welding, screwings.It is less that the bracket base height can be made, even the vehicle frame bottom, also can be used when very near far from ground.Extension spring is positioned on the carriage center face, and in the steady ring that hangs over of two ends, and the steady ring two ends are osed tops.

So this support Parking is stable, easy to use, safe in utilization, extension spring does not come off, main body profile symmetry, smoothness, the commonality height.
