Description
Technical field:
The utility model electric vehicle expansion lock relates to brake member field on the electric vehicle expansion lock with rotatingshaft.
Background technique:
When the electric vehicle expansion lock is with the left and right shoe plate on the promotion rising of the oval axle on the rotatingshaft lock in the past, its left and right shoe plate may upwards jump over, be that left and right shoe plate may swash, after left and right shoe plate swashes, lose and brake the friction catch function of inwall with regard to the friction material that makes left and right shoe plate fixed plate, promptly cause brake failure,, should do new design with the structure of rotatingshaft the electric vehicle expansion lock in order to eliminate above-mentioned contingent fault.
Summary of the invention:
The purpose of this utility model provides a kind of electric vehicle expansion lock rotatingshaft, and rotatingshaft constitutes integral piece by cover plate, oval axle, cylinder axis, square shaft and thread spindle.
A kind of electric vehicle expansion lock rotatingshaft, rotatingshaft 1 is made up of cover plate 2, oval axle 3, cylinder axis 4, square shaft 5 and thread spindle 6, the cover plate 2, oval axle 3, cylinder axis 4, square shaft 5 and the thread spindle 6 that it is characterized in that rotatingshaft 1 are positioned on the same axis, constitute rotatingshaft 1 integral piece, oval axle 3 outsides are connected with cover plate 2, and the inboard is connected with cylinder axis 4 one ends; Square shaft 5 inboards are connected with cylinder axis 4 the other ends, and square shaft 5 outsides are connected with thread spindle 6 the inners.
The utility model electric vehicle expansion lock is as follows with the design principle of rotatingshaft:
1, when rotatingshaft rotates, after oval axle two terminal circle arc bump promotes left and right shoe plate, swash for preventing left and right shoe plate, should cover plate be arranged in the design of oval axle outer end, stop left and right shoe plate to swash.
2, the projection at oval axle two ends is should shape identical, and the rectangle block two ends in the middle of being disposed to symmetrical configuration just can make left and right shoe plate producing balanced forces ground open.
3, cylinder axis should be able to freely rotate in lining.
4, square shaft should be able to match with the square hole in the crank throw fixed end, can drive square shaft and rotate when crank throw rotates.
5, want on the thread spindle retainer nut can be installed, the crank throw fixed end is fixed on the square shaft.
Above-mentioned each should connect and be connected, and be on same the axis, i.e. balanced configuration is on same axis.
The utility model electric vehicle expansion lock is described as follows with the structure of rotatingshaft:
This electric vehicle expansion lock is made up of cover plate, oval axle, cylinder axis, square shaft and thread spindle with rotatingshaft, and cover plate is flat plectane.Oval axle two ends are the identical circular arc-like block of equal and opposite in direction shape, and the centre is a rectangle block, and the height of rectangle block equates that with two terminal circle arc tile height the rectangle block both sides are connected with two ends circular arc piece respectively and form the oval axle, and oval axle outer end is connected with cover plate.
Cylinder axis is an elongated cylindrical, and an end is connected with the oval axle, and the other end is connected with square shaft.
Square shaft is a square block, is rounded down at square shaft four jiaos, and the outer side surface of square shaft is connected with thread spindle is vertical.
Thread spindle is manufactured with outside thread in its outer ring, in its outer end rounded corner is arranged.
The vertical center axis of the vertical center axis of the circle core shaft of described cover plate, oval axle, the vertical center axis of cylinder axis, square shaft and the vertical center axis of thread spindle all are on same the vertical centre axis.
This electric vehicle expansion lock is that processing and fabricating is easy with the rotatingshaft advantage, can produce in batches, can make the electric vehicle expansion lock reliable and secure convenience of braking.
