Abstract

The invention relates to an automatic return cable tightening device of an electric bicycle brake. A frame installation hole is arranged in one end of a support. A supporting block is arranged on the support. The supporting block and the support are integrally fixed. A hole is arranged in the other end of the support. A rotating shaft is arranged in the hole. One end of the rotating shaft is movably riveted with the support through a catch. A flat block is arranged at the other end of the rotating shaft. A bolt hole (which is not specified in the accompanying drawing) is arranged in the flat block. A bolt is arranged in the bolt hole. A brake cable hole is arranged in the bolt. A brake cable shell is arranged at one end of the bolt. A steel cable penetrates through the brake cable hole and a crank and is fixed through a fixing bolt and a fixing nut. During use, the rotating shaft can be freely changed according to the brake cable angle of the bolt hole. The automatic return cable tightening device of the electric bicycle brake has the advantages that not only is the device convenient to install, but also the structure is very simple, the service life is greatly prolonged and the braking effect is improved.

Description

A kind of Electrical Bicycle brake self-return rope tightening device

A kind of Electrical Bicycle brake of the present invention rope tightening device relates more specifically to self-return tight rope support.

Background technology

A kind of disclosed (such as Fig. 1, Fig. 2) Electrical Bicycle brake rope tightening device, rope tightening device is respectively the line component of stopping, the tight rope assembly, the brake assembly, stop line component by line shell 1, wirerope 2 forms, the tight rope assembly is by support 3, nut 4, bolt 5 forms, have the line hole 6 of stopping on the bolt 5, the brake assembly is by crank throw 7, lock shell 8 forms, be provided with eccentric wheel 9 in the lock shell 8, brake shoes 10, one end of crank throw 7 is established brake bolt of rear end plate 11, captive nut 12, eccentric wheel 13 1 ends in the other end of crank throw 7 and the lock shell 8 are fixed, tight-rope rack 3 and brake assembly and electric bicycle fame (this figure does not annotate) are fixing in the lump, it is fixing by bolt of rear end plate 11 and captive nut 12 with crank throw 7 that the wirerope 2 in the line component stopped passes the line hole 6 of stopping that arranges on the tight-rope rack 3, stop line shell 1 and bolt 5 one end in contact, during use, spur the line component of stopping, by the effect of stopping line shell and tight rope support, crank throw moves to the A direction, eccentric wheel 9 rotates, slipper 10 expansions contact with wheel hub 13, reach braking effect, because crank throw 7 moves forward and backward under the line pulling function of stopping, wirerope 2 is angled with tight rope bolt hole 6, cause wirerope 2 constantly to rub in the bolt hole 6 one side b positions that tight rope support 3 arranges, especially wirerope is that a large amount of steel wires process in the shape of a spiral, strengthened the friction dynamics, as long as through several thousand braking maneuvers, the groove shape will be worn and torn in tight rope bolt hole 6 one side b positions, and the line that causes stopping pulling is not smooth, and potential safety hazard is arranged.

The rope tightening device of a kind of swinging strut and lock shell integrative-structure, but because manufacturing process complexity and cost are higher, can not popularize.

A kind of thread fixing plate anchor fitting of stopping of my design, the patent No.: 201110200371.0, because complexity is installed, can not popularize on a large scale.

Summary of the invention

A kind of Electrical Bicycle brake of the present invention self-return rope tightening device is improvements over the prior art, not only easy for installation, and improved service life, the present invention realizes like this, support one end at the tight rope assembly has the vehicle frame mounting hole and in a side anchor plate is set, anchor plate and support are fixed as one, the other end at support has the hole, turning cylinder is set in the hole, turning cylinder is by catch and the movable riveted joint of support, the turning cylinder other end arranges flat blocks, turning cylinder and flat blocks are integrated, have screw on the flat blocks, bolt is set in the screw, have the line hole of stopping on the bolt, during use, the wirerope in the line component stopped passes stop line hole and crank throw and fixes by bolt of rear end plate and captive nut, line shell one end applying bolt one end of stopping, support and brake are fixing in the lump by vehicle frame mounting hole and electric bicycle fame, and support mates by the anchor plate that arranges and brake lock shell one side to be close to, when brake action, reach supporting role, the present invention not only result is simple, and is easy to manufacture, and greatly prolong and stop the line life-span, increase deceleration and stopping performance.

The specific embodiment

Such as Fig. 3, Fig. 4, Fig. 5, support 1 one ends of tight rope assembly have vehicle frame mounting hole 2, and support 1 is provided with anchor plate 3, and anchor plate 3 is fixed as one with support 1, the other end of support has hole 4, the hole 4 interior turning cylinders 5 that arrange, turning cylinder 5 one ends are by the movable riveted joint of catch 6 and support, and turning cylinder 5 other ends arrange unilateral 7, have screw (this figure does not annotate) on the flat blocks 7, bolt 8 is set in the screw, has the line hole 9 of stopping on the bolt 8, the line shell 10 of stopping places an end of bolt, wirerope 11 passes stop line hole and crank throw 12, fixing by bolt of rear end plate 13 and captive nut 14, during use, turning cylinder can change arbitrarily according to the line angle degree of stopping of bolt hole, the present invention is not only easy for installation, and structure is very simple, has greatly increased service life, has improved braking effect.

Claims

1. Electrical Bicycle brake self-return rope tightening device, the interior wirerope of line component of stopping passes the tight rope assembly and crank throw is fixed by bolt of rear end plate and captive nut, an end that it is characterized in that the support of tight rope assembly has the vehicle frame fixed orifice, support and brake are fixing in the lump by vehicle frame mounting hole and electric bicycle fame, the other end of support has the hole, turning cylinder is set in the hole, turning cylinder is by catch and the movable riveted joint of support, the turning cylinder other end is flat blocks, have screw on the flat blocks, bolt is set in the screw, has the line hole of stopping on the bolt.
