Description
The utility model belongs to the damping bicycle vehicle frame.
Existing bicycle scarcely is with Shock absorber, bring dangerous and human discomfort to rider, though there is the bicycle that minority installs various shock absorption devices additional to emerge, but because unreasonable structure, often impaired on up-and-down road surface because of the stressed unreasonable member that causes, damping effect is undesirable, and makes cost higher because of complex structure.
The purpose of this utility model is to propose a kind of later-model damping bicycle vehicle frame, and it can keep vehicle frame steady, safety and comfort when making rider by bike.
The utility model is because front and back wheel all is provided with the full damping frame of elastic shock attenuation, increased bicyclist's safety and comfort sense, rational in infrastructure, the installation seven-piece is wonderful, motion is reliable, and stressed reasonable, damping rate is ridden greatly steadily, and handsome in appearance, be a kind of vehicle that are applicable to rural mountain area and suburb, cities and towns etc.
The purpose of this utility model realizes by following measure: vehicle frame comprises center tap, the preceding pipe of seat tube, vehicle frame bottom and the interior front fork parts of the preceding pipe of the vehicle frame of packing into, it is characterized in that:
A 〉. seat tube top and position, middle and upper part are welded a fork-shaped strut and a fork-shaped pull bar respectively, and this fork-shaped strut is connected with two fork leg correspondences about the pull bar other end, and is provided with tie bolt in the junction,
B 〉. between vehicle frame center tap and rear axle, be provided with H font decoupling rod: be close to solid screw in the center tap one hollow pins is installed, left and right sides decoupling rod is equipped with by gasket sleeve in hollow pins two, two fork mouths are contained in rear axle two respectively about the left and right sides decoupling rod other end that be arranged in parallel, arc cross shock mount is housed between strut and rear axle
C 〉. the fork leg is made of with the damping tube that withstands spring the interior protective tube that is packaged with spring respectively about front fork; the damping tube epimere has the part of draw-in groove and inserts in the protective tube; and make draw-in groove on the damping tube align screw hole on the protective tube; screw is screwed in the draw-in groove after by protective tube protective tube and damping tube is linked together
Described arc cross shock mount is made up of the helical spring left and right sides of overcoat arc portable bar, the moving casing of band Spring Card is loaded on arc portable bar epimere, the Spring Card on the sleeve pipe is withstood on spring top, there are a connection pipe and moving casing to be the criss-cross weld together, left and right sides connection pipe is corresponding continuous with the tie bolt of pull bar inboard, connects a trammel beam in two arc portable bars upper end.
Be described further below in conjunction with embodiment of the present utility model and accompanying drawing thereof.
The damping frame mounting structure scheme drawing that Fig. 1 the utility model proposes for foundation.
Fig. 2 is the decomposing schematic representation of damping frame structure.
Damping frame as shown in the figure comprises the front fork parts in center tap (10), the preceding pipe of vehicle frame (1) of seat tube (7), vehicle frame bottom and the preceding pipe of the vehicle frame of packing into.Seat tube top and middle and upper part are welded a upright fork-shaped strut (6) and a chain stay shape pull bar (8) respectively, and this fork-shaped strut is connected with two fork leg correspondences about the pull bar other end, and is fixed with tie bolt (20) in the junction.
Between vehicle frame center tap and rear axle (13), be provided with H font decoupling rod: be close to solid screw in the center tap one hollow pins (11) is installed, hollow pins tightens together by screw and center tap, the axis parts are installed in the hollow pins, and left and right sides crank and pedal parts still are installed in the axis two ends routinely.When the pedal bicycle advances, hollow pins can together not rotated, decoupling rod (9) one ends in the left and right sides respectively are socketed in the hollow pins both sides, after the assembling, decoupling rod can be swung around hollow pins, between decoupling rod connection running-on and hollow pins packing ring (21) is housed, two fork mouths of the left and right sides decoupling rod other end that be arranged in parallel are contained in rear axle two respectively, are equipped with fixed by nut.Pipe link (12) is arranged between the decoupling rod of the left and right sides, and this connecting rod middle part has the fixedly screw hole of mud plate member.One arc cross shock mount is housed between strut and pull bar coupling end and the rear axle.
Arc cross shock mount is made up of the left and right sides arc portable bar (14) of overcoat coil spring (15), the moving casing (17) of band Spring Card (16) is loaded on arc portable bar epimere, the Spring Card on the sleeve pipe is withstood on coil spring top, have that across is welded to each other together between a connection pipe (19) and the moving casing, the tie bolt (20) that connection pipe installs to the pull bar inboard is gone up and is fastening with nut, and the lower end of portable bar is sleeved on rear axle two and fastening by the nut on both sides.Epimere was made taper after the arc portable bar passed moving casing, trammel beam (18) is connected on the thread segment of two arc portable bars upper ends and by nut trammel beam is captiveed joint with the top of left and right sides arc portable bar, and there is the screw hole of installation mud plate member at the trammel beam middle part.Be contained in that moving casing on the arc portable bar has corresponding to garden arc, portable bar can up-and-down movement under the effect of spring (15), and the rear portion that drives decoupling rod (9) is that radius is up and down with vehicle frame center tap axle center.
Because what when driving produced jolts, tire is impacted, and decoupling rod is a fulcrum with the hollow pins at center tap place, and the other end acts on the arc portable bar lower end of arc shock mount, makes it the upward movement compression spring and plays the shock-absorbing effect.
Behind the pipe, the screw thread of upper end partly just exposes above the pipe before vehicle frame vertical tube of front fork (2), can install parts such as retaining, lamp bracket, front fork locknut before the following threading vehicle frame.The front-wheel damping is to reach by improved front fork parts: the fork leg is made up of the interior damping tube (4) that is packaged with the protective tube (3) of compression spring (22) and withstands spring respectively about front fork; the damping tube epimere has the part of draw-in groove (5) and inserts in the protective tube; and make draw-in groove on the damping tube align the screw hole of protective tube inboard; screw is screwed into outside protective tube the draw-in groove protective tube and damping tube is linked together; guarantee that damping tube can not come off from protective tube; under the effect of compression spring damping tube can be in protective tube up-and-down movement; the damping tube inboard has the screw hole (23) that the mud plate member is installed in the middle of being positioned at, and the lower end is contained on the front axle by the front fork mouth and is fastening by the nut on both sides.
