Description
Technical field:
The utility model electric vehicle expansion lock relates to left shoe plate and the right shoe plate of installing and using on the electric vehicle expansion lock with left shoe plate and right shoe plate.
Background technology:
Though the left shoe plate of use different structure designs and right shoe plate are in same material on electric vehicle expansion lock and servant brake, same thickness, hold equally under the power of stopping and the same number of times that applies moment, on left side shoe plate and the right shoe plate, the gap deflection is different down, if this gap deflection is very big, concerning servant brake, left side shoe plate will swash, for the lock that rises, a left side, right shoe plate all can swash, cause left shoe plate and right shoe plate can't open work during brake, cause brake to lose efficacy, produce train operation accident, take for the motor battery-driven car is double especially, (as 30 kilometers of speed per hours) travels or up the sailing when braking on the descending road surface under higher speed, then can produce serious train operation accident, therefore, manufacturer should design, the left shoe plate and the right shoe plate of development different structure, make the deflection minimum of its generation, braking effect is best.
Summary of the invention:
The purpose of this utility model provides a kind of electric vehicle expansion lock with left shoe plate and right shoe plate, design and produce the T type reinforced rib that constitutes by main body straight line reinforced rib and main body circular arc reinforced rib in the upper and lower of left shoe plate and right shoe plate, deflection is very little after making left shoe plate and right shoe plate work, guarantees traffic safety.
A kind of electric vehicle expansion lock is characterized in that with left shoe plate and right shoe plate the last T type reinforced rib that is connected and composed by upper body circular arc reinforced rib and upper body straight line reinforced rib is arranged at the top of left shoe plate and right shoe plate; The following T type reinforced rib that is connected and composed by sub-body circular arc reinforced rib and sub-body straight line reinforced rib is arranged in the bottom of left shoe plate and right shoe plate, and last T type reinforced rib and following T type reinforced rib are disposed at the upper and lower both sides of horizontal shaft at intervals.
The left shoe plate and the right shoe plate of electric vehicle expansion lock or servant brake generally form by the cold-strip steel Punching Technology, there is the left and right shoe plate of single circular arc reinforced rib applying under the same moment compared with punching press at not punching press reinforced rib on the left and right shoe plate, the deflection that produces is bigger, its braking effect is just not as having the left and right shoe plate of single circular arc reinforced rib, development further proves if adopt T type structural bead, applying under the same moment, the deflection minimum that is produced, then braking effect is better.
Now, structure and the shape of this electric vehicle expansion lock with left shoe plate and right shoe plate is described as follows:
Left side shoe plate: in left shoe plate horizontal axis upper and lower a T type reinforced rib is arranged respectively respectively, T type reinforced rib is formed by connecting by main body circular arc reinforced rib and main body straight line reinforced rib respectively, between upper and lower two T type reinforced ribs the certain clearance distance is arranged.In left shoe plate upper end the moulding boss is arranged, in the upper and lower outside of moulding boss upper and lower limit circle of position angle is arranged respectively, between upper and lower limit circle of position angle, locating aperture is arranged, on left shoe plate body, upper and lower spring mounting hole is arranged, with the upper and lower spring fillet of stepping down, contact pin riveted joint plane is arranged in left shoe plate bottom, can rivet contact pin on it.
Right shoe plate: a T type reinforced rib is respectively arranged respectively in right shoe plate horizontal axis upper and lower, equally, T type reinforced rib is formed by connecting by main body circular arc reinforced rib and main body straight line reinforced rib respectively, between upper and lower two T type reinforced ribs certain spacing distance is arranged, have by upper and lower limit circle of position angle in the upper end of right shoe plate and to enclose the locating aperture that constitutes, upper and lower spring mounting hole and the upper and lower spring fillet of stepping down is arranged on the shoe plate body of right shoe plate, contact pin riveted joint plane is arranged in right shoe plate bottom, can rivet contact pin on it.
The locating aperture of above-mentioned left and right shoe plate is installed by centering spindle and is linked together, and promptly the locating aperture of left and right shoe plate is installed in the cylinder axis of centering spindle.
The utility model electric vehicle expansion lock has T type reinforced rib with left shoe plate and right shoe plate owing to punching press, after applying the moment use, clearance distance between left and right shoe plate is little, and promptly deflection is little, and its drag effect has single circular arc reinforced rib effective than left and right shoe plate on punching press.Guaranteed the driving safety of battery-driven car.
