Description
Technical field
The utility model relates to motor-tricycle, more particularly, relates to the back braking draw gear of motor-tricycle.
Background technology
The back braking draw gear of tradition motor-tricycle is a rod-pulling type, and pull bar is made by round bar, and its front end is hinged with the braking pivoted arm, and the braking pivoted arm is driven by rear brake pedal, and the brake control lever of back end of tie rod and back stop mechanism is hinged.The pull bar that round bar is made has certain degree of hardness, and direct the connection with brake control lever with the braking pivoted arm of pull bar two ends gets final product, and do not need to use in addition stent support.Exactly because but also pull bar is a rigid material, not flexible, after compartment load-carrying steel spring was depressed into to a certain degree, back axle moved after the meeting, and pull bar fixedly is tightened up owing to length, brake control lever rotates realizes braking, cause motor bike to start to walk, have only setting nut pine to move back, make the brake control lever reduction of stop mechanism the pull bar front end, the ability brake off causes and uses inconvenience.
The utility model content
Technical problem to be solved in the utility model is: a kind of back braking draw gear of motor-tricycle is provided, and when moving behind the compartment load-carrying back axle, back stop mechanism can not produce braking.
The technical solution of the utility model is as follows: a kind of back braking draw gear of motor-tricycle, comprise drag-line and the empty outer gum cover of this drag-line that is enclosed within, the front and back ends of this drag-line stretches out from described gum cover, and is hinged with the brake control lever of braking pivoted arm with the back stop mechanism respectively; Described gum cover is by forward and backward support fixed pedestal, and described front frame is fixed on the back flat frame of vehicle frame, and described after poppet is fixed on the steel spring.
The utility model changes traditional rigidity steel bar pull bar into flexible drag-line, the brake control lever that to be braked pivoted arm and stop mechanism by the two ends of drag-line is connected, and drag-line is set with gum cover outward, the two ends of gum cover are supported by front frame and after poppet, because drag-line and gum cover all are flexible materials, at forward and backward support fixedly during gum cover, the loose surplus that leaves of gum cover, promptly in the gum cover length between the forward and backward support greater than the distance between the forward and backward support attachment point, when back axle then moves because of the compartment load-carrying, brake control lever can not rotate because gum cover is tightened up, thereby avoids producing braking.
Further, for ease of installing and arranging, described front frame is welded on the back flat frame curb girder of vehicle frame, described gum cover front end is provided with screw collar, on this screw collar, be provided with setscrew nut and jam nut, described drag-line and gum cover pass this front frame, are fixed on the described front frame by jam nut and the setscrew nut front end with gum cover.
Further, for ease of installing and arranging that described after poppet comprises orthogonal base plate and adapter plate, described base plate is fixed on the leaf spring pressing plate of described steel spring by clevis bolt and nut; Described gum cover rear end is provided with screw collar, is provided with setscrew nut and jam nut on this screw collar, and described drag-line and gum cover pass this after poppet, is fixed on the described after poppet by jam nut and the setscrew nut rear end with gum cover.
Further, the front end of described drag-line is provided with the preceding bearing pin vertical with drag-line, and is after preceding bearing pin passes the braking pivoted arm, spacing by the spring cotter of axle head.
Further, the rear end of described drag-line is provided with U-shaped fork plate, and this U-shaped fork plate fork is on described after poppet, and is after rear pin shaft passes the brake control lever of U-shaped fork plate and back stop mechanism, spacing by the spring cotter of rear pin shaft end.
Further, be support cable and gum cover better, described drag-line and gum cover also pass protective ring, and described protective ring is fixed on before the steel spring on the hanger, makes the flexible gum cover that has unnecessary length between forward and backward support two attachment points can not rock.
The beneficial effects of the utility model are: use the utility model, when moving behind the compartment load-carrying back axle, back braking draw gear can not be tightened up, thereby avoids the back stop mechanism to produce braking.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As depicted in figs. 1 and 2, the utility model is two, lay respectively at the and arranged on left and right sides of the back flat frame 7 of vehicle frame, be used for two trailing wheels are braked respectively, the utility model comprises drag-line 1 and gum cover 2, gum cover 2 skies are enclosed within outside the drag-line 1, and the front and back ends of this drag-line 1 stretches out from gum cover 2, and the front and back ends of drag-line 1 is hinged with the brake control lever 4 of braking pivoted arm 3 with the back stop mechanism respectively.Two braking pivoted arms 3 are fixed on the two ends of rotating shaft 15, and rotating shaft 18 passes across the flat frame 7 in back, and rotating shaft 15 is supported on two curb girders of the flat frame 7 in back.Gum cover 2 is by forward and backward support 5,6 fixed pedestals, and front frame 5 is fixed on the flat frame 7 in back, and after poppet 6 is fixed on the steel spring 8.As shown in figures 1 and 3, front frame 5 is an angle steel, it vertically is welded on the curb girder of the flat frame 7 in back, the front end of gum cover 2 is provided with screw collar, on this screw collar, be provided with setscrew nut 21 and jam nut 22, drag-line 1 and gum cover 2 pass this front frame 5, are fixed on the front frame 5 by jam nut 22 and setscrew nut 21 front end with gum cover 2.As shown in Figure 6 and Figure 7, be provided with the preceding bearing pin 12 vertical with drag-line 1 at the front end of drag-line 1, after preceding bearing pin 12 passes braking pivoted arm 3, spacing by the spring cotter 15 of preceding bearing pin 12 axle heads.
As shown in Figure 4 and Figure 5, after poppet 6 comprises orthogonal base plate 61 and adapter plate 62, and base plate 61 is fixed on the leaf spring pressing plate 11 of steel spring 8 by clevis bolt 9 and nut 10.To shown in Figure 6, be provided with screw collar in the rear end of gum cover 2 as Fig. 4, be provided with setscrew nut 21 and jam nut 22 on this screw collar, drag-line 1 and gum cover 2 pass this after poppet 6, are fixed on the after poppet 6 by jam nut 22 and setscrew nut 21 rear end with gum cover 2.As Fig. 4, Fig. 5 and shown in Figure 8, be provided with U-shaped fork plate 13 in the rear end of drag-line 1, these U-shaped fork plate 13 forks are on the adapter plate 62 of after poppet 6, and are after rear pin shaft 14 passes the brake control lever 4 of U-shaped fork plate 13 and back stop mechanism, spacing with spring cotter 15 at the axle head of rear pin shaft 14.
As shown in Figure 1, front frame 5 and after poppet 6 are fixedly during gum cover, gum cover between two stands leaves unnecessary length, drag-line 1 and gum cover 2 also pass protective ring 16, support by protective ring 16, protective ring 16 is located between front frame 5 and the after poppet 6, and protective ring 16 is fixed on the preceding hanger 17 of steel spring, makes the flexible gum cover 2 that has unnecessary length between 5,6 liang of attachment points of forward and backward support can not rock.Because the gum cover 2 between the forward and backward support 5,6 is not tight, leaves unnecessary length, when back axle because of the compartment load-carrying then moves, when after poppet 6 moves after following, brake control lever 3 can not rotate because gum cover 2 is tightened up, thereby avoids producing braking.
