Abstract

The utility model relates to a flywheel tension rod type reversed brake mechanism, in particular to a brake mechanism on a bicycle or a tricycle, which overcomes the disadvantages of other brake technologies. The utility model adopts the structure that one end of the inner hole of a flywheel is fixed at the inner side of the left pedal elbow piece of a bicycle or a tricycle and is coaxial with a middle axle; a rib plate is welded on the side surface of the teeth on the flywheel periphery, hinges are connected between the rib plate and a fixing tension rod, the fixing tension rod and an adjustable tension rod, and a u-shaped plate and a brake rocker lever, and a cylindrical pin is inserted into a pin hole; the adjustable tension rod is matched and connected with the u-shaped plate through threads; a compression spring sleeve can be arranged on the adjustable tension rod, and positioned between a fixing baffle plate and the u-shaped; the operating distance of the spring can be adjusted by rotating the adjustable tension rod, and a brake is installed on a rear hub; the casing body of the brake is fixed on a rear axle; the brake rocker lever is installed on the brake. The flywheel tension rod type reversed brake mechanism has the advantages of smooth and reliable braking, long service life and safe bicycle riding.

Description

Flywheel rod-pulling type reversing stop mechanism

One, technical field: the utility model relates to the brake equipment on a kind of bicycle, the three-wheel vehicle, especially flywheel rod-pulling type reversing stop mechanism.

Two, background technology: the bicycle of Chu Shouing in the market, the overwhelming majority all is the manual wire-drawing type brake equipment, backguy is combined by steel wire and overcoat, period of service not length will get rusty, after getting rusty, the friction force of steel wire and overcoat increases, and M/C is difficulty very, often finds that the steel wire head is broken and caused the malfunctioning dangerous situation of back brake.

Three, summary of the invention: the purpose of this utility model provides a kind of braking steadily and failure-free flywheel rod-pulling type reversing stop mechanism, it has overcome the shortcoming that other braking technology exists, the purpose of this utility model is to exist like this, it is to be formed by connecting by flywheel, gusset, straight pin, steady brace, fixed dam, adjustable rod, stage clip, u plate, drg rocking bar, brake casing, and flywheel endoporus one end is fixed on bicycle or the three-wheel vehicle left foot turns inboard and coaxial with axis; Gusset is welded on the flywheel periphery tooth side, and gusset all adopts hinge to be connected with adjustable rod, u plate with drg rocking bar three places with steady brace, steady brace, and straight pin inserts in the pin-and-hole; Adopt screw thread fit to be connected between adjustable rod and the u plate; Compression spring sleeve is on adjustable rod, and between fixed dam and u plate; Rotate adjustable rod, can adjust the operating distance of spring, drg is installed on the backshaft skin; Brake casing is fixed on the rear axle; The drg rocking bar is installed on the drg.

Principle of work: when bicycle advanced, flywheel was as antifriction-bearing box, and interior aperture member rotates with axis, and the periphery dental part maintains static, and at this moment, pull bar is also motionless, drg is in Neutral Position, when the place ahead was in an emergency the needs brake, two pin driving pin were being kidnaped flywheel and are being reversed together, and the flywheel drive stay moves forward a segment distance, the drg rocking bar is pulled to braking position, trailing wheel stops operating, and simultaneously, spring is compressed a segment distance; When needing to advance again, as long as pin just turns and changes, spring releases energy at once, and rocking bar is pushed to Neutral Position.

Benefit of the present utility model is, braking steadily and reliable, and is and durable in use, and the brake task has been given pin and liberated hand, and like this, hand will attentively be used for holding the direction of advancing, and is just safer by bike.

Four, description of drawings: Fig. 1 is the structural representation of flywheel rod-pulling type reversing stop mechanism, among the figure 1, flywheel 2, gusset 3, straight pin 4, steady brace 5, fixed dam 6, adjustable rod 7, stage clip 8, u plate 9, drg rocking bar 10, brake casing

Fig. 2 is the gusset scheme drawing

Fig. 3 is the steady brace scheme drawing

Fig. 4 is the adjustable rod scheme drawing

Fig. 5 is a u plate scheme drawing

Five, the specific embodiment: in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, flywheel 1 endoporus one end is fixed on bicycle or the three-wheel vehicle left foot turns inboard and coaxial with axis; Gusset 2 is welded on the flywheel 1 periphery tooth side, and gusset 2 all adopts hinge to be connected with adjustable rod 6, u plate 8 with drg rocking bar 9 three places with steady brace 4, steady brace 4, and straight pin 3 inserts in the pin-and-hole; Adopt screw thread fit to be connected between adjustable rod 6 and the u plate 8; Stage clip 7 is enclosed within on the adjustable rod 6, and between fixed dam 5 and u plate 8; Rotate adjustable rod 6, can adjust the operating distance of spring, drg is installed on the backshaft skin; Brake casing 10 is fixed on the rear axle; Drg rocking bar 9 is installed on the drg.
