Description
Technical field:
The utility model electric vehicle expansion lock relates to the electric vehicle expansion lock centering spindle's assembly that is installed on the electric vehicle expansion lock shell with centering spindle's assembly.
Background technology:
On the electric vehicle expansion lock, for the hoof piece group that left and right shoe plate is constituted is installed on the lock shell that rises, the left and right shoe plate that just need will have fixed plate, contact pin and friction material by the connecting element of a centre is installed in the lock lock shell that rises together, promptly need the C type draw-in groove of left and right shoe plate is installed on the cylinder axis of the centering spindle on the electric vehicle expansion lock, then, also centering spindle to be installed on the lock lock shell that rises, therefore, will design centering spindle with definite shape and structure, and in centering spindle, to assemble certain accessory, form electric vehicle expansion lock centering spindle's assembly.
Summary of the invention:
The purpose of this utility model provides a kind of electric vehicle expansion lock centering spindle's assembly, on the threaded shaft of centering spindle's assembly, add cover plate and black nut, the cylinder axis two ends are connecting thread axle and support cylinder respectively, and the support cylinder other end is connected with the riveted joint cylinder, constitutes centering spindle's assembly.
A kind of electric vehicle expansion lock centering spindle's assembly, on threaded shaft, add cover plate and black nut, the threaded shaft bottom is connected with cylinder axis, the cylinder axis bottom is connected with support cylinder, the support cylinder bottom is connected with the riveted joint cylinder, threaded shaft, cylinder axis, support cylinder and riveted joint cylinder constitute centering spindle's body integral piece, and above-mentioned each parts balanced configuration is in longitudinal axis both sides.
This electric vehicle expansion lock is to possess following function with centering spindle's unit construction design-calculated principle:
(1) left and right shoe plate can be installed in the centering spindle.
(2) to make the left and right shoe plate that clamps in the centering spindle not take place axially to throw.
(3) to make centering spindle's other end energy riveted and fixed on the lock shell.
This electric vehicle expansion lock is made up of centering spindle's body and cover plate and black nut on the threaded shaft that is installed at centering spindle's body with centering spindle's assembly.
Add cover plate and black nut on the threaded shaft of centering spindle's body, the black nut that is installed in threaded shaft top is pressed on the last plane of cylinder axis of centering spindle's body the cover plate that is installed in the threaded shaft bottom; Cover plate can make the left and right shoe plate that is installed on the cylinder axis not take place axially to throw.
The C type draw-in groove of left and right shoe plate can be installed on the cylinder axis, and left shoe plate is installed in below the cylinder axis, right shoe plate be installed in cylinder axis above, cylinder axis is connected with threaded shaft.
The cylinder axis other end is connected with support cylinder, the height of support cylinder has just guaranteed the distance between interior mounting plane of lock shell and the left shoe plate lower plane, be that mounting plane coincides in nose circle face of support cylinder and the lock shell, another nose circle face and the left shoe plate lower plane of support cylinder coincide.
The other end of support cylinder is connected with the riveted joint cylinder, is the semi-hollow structure in the riveted joint cylinder, and the riveted joint cylinder plays the role of positioning centering spindle's body on the lock shell, because the flange of riveted joint cylinder makes centering spindle's body and lock shell rivething together in the front of lock shell.
This electric vehicle expansion lock is simple in structure with centering spindle's assembly advantage, and processing and fabricating is convenient.

The specific embodiment:
Referring to each accompanying drawing, among each figure: 1 is centering spindle's assembly, and 2 is threaded shaft, and 3 is cylinder axis, and 4 is support cylinder, and 5 are the riveted joint cylinder, and 6 is cover plate, and 7 is black nut.
As shown in Figure 1, add black nut 2 on threaded shaft 2 tops, black nut 2 is the nylon black nut; Threaded shaft 2 bottoms add cover plate 6, and cover plate 6 has endoporus, the endoporus of cover plate 6 and threaded shaft 2 free-running fits, and black nut 2 is pressed on the last plane of cylinder axis 3 cover plate 6, and cover plate 6 is a circular cover, and cover plate 6 diameters are greater than the diameter of cylinder axis 3.
As shown in Figure 5, left shoe plate and right shoe plate can be installed on cylinder axis 3, the C type draw-in groove of promptly left shoe plate and right shoe plate can be installed on the cylinder axis 3, and left shoe plate is on top, and right shoe plate is in the bottom, and left and right shoe plate all can rotate at cylinder axis 3.
As shown in Figure 5, the height of support cylinder 4 distance between the mounting plane and left shoe plate lower plane in the lock shell that guaranteed to rise.The diameter of support cylinder 4 is greater than the diameter of cylinder axis 3.
As shown in Figure 7, riveted joint cylinder 5 is semi-hollow riveted joint cylinder, riveted joint cylinder 5 is connected with support cylinder 4, riveted joint cylinder 5 diameters are less than the diameter of support cylinder 4, make centering spindle's assembly 1 in the lock shell that rises, play positioning action, rivet cylinder 5 and rise by the lock shell rivething together, as shown in Figure 5, the flange of riveted joint cylinder 5 is in the front of rising by the lock shell.
