Abstract
The utility model is an open-loop resetting spring on an internal expansion follow-up gate for electrical bicycles, which relates to a resetting spring arranged on an internal expansion follow-up gate lining of an electrical bicycle. The open-loop resetting spring (1) comprises two lining hole plug columns (2) and spring collars (3); the two lining hole plug columns (2) are spaced with a certain partition arc, and connected with two end vertical bends of the spring collar (3), so that an integrated component can be formed into the open-loop resetting spring (1); the rectangular sections of the two lining hole plug column (2) are the same as the rectangular sections of the spring collar (3) in shape, and the section areas are identical. The open-loop resetting spring (1) has the advantages of high elastic force, quick resetting, durability and convenient installation.
Description
Technical field:
The utility model battery-driven car internal expanding servant brake relates to the retracing spring that is installed on the battery-driven car internal expanding servant brake shoe plate with the open loop type retracing spring.
Background technology:
On the left and right shoe plate of battery-driven car internal expanding servo brake shoe piece group, often to distinguish a cylindrical retracing spring respectively is installed, when left and right shoe plate during by the spreading drag, because this cylindrical retracing spring elastic force is big inadequately, therefore, left and right shoe plate resets fast inadequately, thereby, influence the durability of braking effect and cylindrical retracing spring.Therefore, should design that elastic force is big, the hoof piece group retracing spring of reset fast and durable new structure and shape.
Summary of the invention:
The purpose of this utility model provides a kind of battery-driven car internal expanding servant brake open loop type retracing spring, this open loop type retracing spring inserts post by the shoe bores of vertical bending and spring coil is formed, two shoe bores are inserted the space interval radian that post is separated by certain, and spring coil is isometrical open loop type circular arc ring.
A kind of battery-driven car internal expanding servant brake open loop type retracing spring, open loop type retracing spring (1) inserts post (2) by two shoe bores and spring coil (3) is formed, it is characterized in that the space interval radian that two shoe bores insertion posts (2) are separated by certain mutually, and be connected with the vertical bending in spring coil (3) two ends respectively, two shoe bores are inserted post (2) and spring coil (3) formation open loop type retracing spring (1) integral piece.
The utility model battery-driven car internal expanding servant brake is as follows with the principle of work of open loop type retracing spring:
Two shoe bores of this open loop type retracing spring are inserted post and are inserted respectively in the left and right shoe bores that is installed in left and right shoe plate, when left and right shoe plate opens glancing impact, this open loop type retracing spring that then is installed on the left and right shoe plate is also opened thereupon to the left and right sides, when the line of stopping stops to brake, then left and right shoe plate is under the elastic force of above-mentioned open loop type retracing spring, reset to original not open state, because the elastic force of this open loop type retracing spring is big, therefore, left and right shoe plate is resetted soon, and can be durable in use.
This battery-driven car internal expanding servant brake is described as follows with the structure and the shaped design of open loop type retracing spring:
This open loop type retracing spring inserts post by left and right two shoe bores and spring coil is formed, left and right two shoe bores are inserted the alternate certain space interval radian of intercolumniation, left and right two shoe bores are inserted post and are connected with the vertical bending in left and right two ends, spring coil top respectively, and the cross sectional shape that left and right two shoe bores are inserted post and spring coil is all identical, and sectional area is equal fully.
Left and right two shoe bores of described open loop type retracing spring are inserted post and are inserted into respectively in the shoe bores that is installed in left and right shoe plate, and spring coil then is placed in the battery-driven car internal expanding servant brake fuse-box between left and right two shoe plates.Described open loop type retracing spring opens along with opening of left and right shoe plate, and can under the spring force effect of this open loop type retracing spring left and right shoe plate be automatically reset.
The advantage of this open loop type retracing spring is: elastic force is big, it is fast, durable, easy for installation to reset.
Description of drawings:
Fig. 1: be this battery-driven car internal expanding servant brake open loop type retracing spring (1) schematic three dimensional views.
Fig. 2: for this battery-driven car internal expanding servant brake is looked scheme drawing with open loop type retracing spring (1) master.
Fig. 3: be this battery-driven car internal expanding servant brake open loop type retracing spring (1) schematic side view.
The specific embodiment:
Referring to Fig. 1, Fig. 2 and Fig. 3: among each figure: (1) is the open loop type retracing spring, and (2) are that shoe bores is inserted post, and (3) are spring coil.
Two shoe bores are inserted post (2) and are connected with vertical bending ground, the two ends of spring coil (3) respectively at mutually same side direction, spring coil (3) is the spring coil of two ends open loop type, the center of circle branch of spring coil (3) is clipped to two shoe bores and inserts post (2) root radius lines and equate and be symmetrical in spring coil (3) vertical center line, be that these two shoe bores are inserted post (2) roots and equated with two angles between spring coil (3) vertical center line to the circle center line connecting of spring coil (3), space interval radian between these two shoe bores insertion posts (2) that spring coil (3) two ends vertically link to each other is greater than 15 °, less than 90 °.
The cross section of two shoe bores insertion posts (2) is the identical rectangular cross section, and the cross section of spring coil (3) also is the square-section, and the square-section of two shoe bores insertion posts (2) is identical with the rectangular cross sectional shape of spring coil (3), and area equates.
This open loop type retracing spring (1) is for inserting the integral piece that post (2) is connected with the vertical bending in spring coil (3) two ends by two shoe bores.
Claims (4)
