Abstract
The utility model relates to the manufacturing technique of a manpower vehicle, which is composed of an elastic component and a locating mechanism thereof, wherein, one end of the elastic component is connected with a vehicle body (frame), and the other end of the elastic component is connected with a wheel main axle or an axle support component thereof. When a helical compression spring is used, the locating mechanism is a movable telescoping mechanism which is composed of a conduit and a guide rod. When a plate spring is used, the positioning mechanism is a convex component which is arranged on the vehicle body, and the convex component can be used as a support point of spring stress deformation. The utility model replaces a rigid connection componect between the vehicle body and the wheel axle of the prior art, and can effectively reduce and eliminate shake. Users can feel comfortable, and the service life of the vehicle body can be prolonged.
Description
The utility model relates to rickshaw a piece of wood serving as a brake to halt a carriage manufacturing technology.
In the prior art, the car body and the Wheel shaft of rickshaw a piece of wood serving as a brake to halt a carriage all are rigidly connected, because road is uneven, make that wheel is upper and lower to jolt, drive car body and the person of taking advantage of or the upper and lower vibration of goods, this has not only influenced the person's of taking advantage of level of comfort, has also quickened the damage of car body simultaneously.
The purpose of this utility model is that when making rickshaw travel on up-and-down road, the body oscillating degree greatly reduces, thereby the person of taking advantage of is felt comfortably cool by improving the connection mode of car body and wheel, and prolongs the service life of car body.
The purpose of this utility model realizes in the following manner.
Rickshaw shock absorption device described in the utility model is made up of elastic component and detent mechanism thereof, for example with helical compression spring or leaf spring as elastic component, this elastic component one end is connected on car body/frame, the other end is connected with Wheel shaft or its supporting member.
When using helical compression spring as elastic component, the movable telescopic mechanism that described detent mechanism is made up of conduit and guide rod, in guide rod and the conduit one is fixed into integral body with car body, another is connected on the Wheel shaft supporting member, helical compression spring is set on the conduit outside or is positioned in the conduit endoporus, the relative compression distance of conduit and guide rod is greater than the compressible stroke of stage clip, to guarantee to make full use of elasticity.
When using the bar shaped leaf spring as elastic component, described detent mechanism is that two or more are located at the projection piece on the car body, for example bearing pin, bolt shaft etc., they contact with upper and lower two surperficial x wires of bar shaped leaf spring respectively, supporting-point and spacing stop when being the spring stress distortion.One end of described leaf spring and car body are hinged, and the other end and Wheel shaft are connected.
Compared with prior art, because the utility model uses elastic component to connect car body and Wheel shaft, original rigid connector replaces, jolting of wheel dashed through elastic component shock absorbing silk ribbon attached to an official seal or a medal, the vibrations of passing to car body are greatly reduced, make the person of taking advantage of comfortable, also prolong the service life of car body simultaneously effectively.
Be further described below in conjunction with embodiment and accompanying drawing.
Fig. 1 is to be the structural representation of elastic component with helical compression spring.
Conduit among the figure (2) is fixed on the vehicle frame (1), the intrinsic guide pin bushing in guide rod (6) top (4), in the conduit endoporus, be provided with back-up ring (5), be free-running fit between the endoporus of guide pin bushing and back-up ring and guide rod, its back-up ring can prevent on the one hand guide rod therefrom landing get off, also played directional tagging on the other hand, helical compression spring (3) is sleeved on the periphery of conduit, and the slide relative of guide rod and conduit distance is greater than the compressible stroke of stage clip.The axle supporting (9) of the bottom of guide rod and Wheel shaft is fixed into integral body, and this supporting and main shaft are interference fit, uses antifriction-bearing box in being connected of wheel (7) and main shaft (8), and is reliable with the assurance stability of rotation.
Car a piece of wood serving as a brake to halt a carriage when the wheel that rolls runs into protruding object, by the effect of axletree and guide rod, make compression spring produce compressive deformation, and car body still is in than the pulsation-free state in the process of moving, thereby little to occupant's influence, makes it that comfort be arranged.Present embodiment should be used for three-wheel vehicle, wooden handcart etc.
Fig. 2 is another kind of example structure scheme drawing.(7) are wheels among the figure, be arranged with two shock absorption devices of forming by helical compression spring and detent mechanism thereof in the wheel both sides, helical compression spring (3) is arranged in the endoporus of conduit (2), present embodiment can be advantageously used in the front-wheel of bicycle, the existing front fork of bicycle can be changed system into conduit, and helical compression spring is placed in its vestibule.
Fig. 3 is the structural representation that is applicable to bicycle rear.In the present embodiment, set up an arc support (10) in its detent mechanism, guide rod (6) is hinged with Wheel shaft, and also cover is fixed with a connecting rod (11) on Wheel shaft (8), and the other end of this connecting rod is hinged on the arc support.This connecting rod defines the scope of conduit side-to-side movement on the one hand, also Wheel shaft has been played the aiding support effect simultaneously.When car a piece of wood serving as a brake to halt a carriage travelled, under the comprehensive work of conduit and connecting rod, wheel upper and lower jolted to be converted to and is located at helical compression spring compression--the circulating motion that resets on the conduit periphery.
Fig. 4 utilizes the structural representation of bar shaped leaf spring as elastic component.
Fig. 5 is the A-A cutaway view of Fig. 4.
Among the figure, (17) be housing shape support, its upper plate is porose, use threaded connector to be fixed on the car body, (12) are the bar-spring steel plate, place the inner chamber of (17), the two ends of this leaf spring are curled into circular hole respectively, be coated with bolt shaft (13) in the left end hole, this is bolted on the support two side, and leaf spring can rotate with respect to bolt shaft.The right-hand member hole is set on Wheel shaft and captive joint, is provided with pivot bolt (14) on the sidewall of housing shape support, and the upper surface of it and leaf spring contacts the fulcrum when being the leaf spring stress deformation.Right part at housing shape support also is provided with upper and lower spacing bolt (16) (15), and distance between the two is the stressed range of answering shape of leaf spring.The axis of pivot bolt (14) and upper and lower spacing bolt (16), (15) all with the parallel axes of bolt shaft (13).When car a piece of wood serving as a brake to halt a carriage travelled on the level land, leaf spring (12) was in the midway location of upper and lower spacing bolt, when running into when rough and uneven in surface, the former upwards is out of shape by leaf spring, until contacting with the upper limit bolt, latter's distortion downwards progressively resets then until contacting with the lower limit bolt.Like this, jolt although wheel is upper and lower, very little to the influence of car body, the embodiment of this structure should be used for wooden handcart or three-wheel vehicle etc.
Of the present utility model simple in structure, low cost of manufacture is applicable to the existing rickshaw producer that produces, and original product is upgraded.
