Abstract
The invention discloses a slotted friction plate servo brake shoe group, and relates to the field of servo brake shoe groups of electric vehicles. A right shoe (2) of the slotted friction plate servo brake shoe group (1) is riveted with a joint plate (4) and is embedded with a right shoe fixing plate (8), and a right friction plate (10) is arranged on the right shoe fixing plate (8). A left shoe fixing plate (9) is embedded in a left shoe (3), and a left friction plate (11) is arranged on the left shoe fixing plate (9). A plurality of inwards grooves are formed on the right friction plate (10) and the left friction plate (11) respectively, and the right shoe (2) and the left shoe (3) are connected together by a fixed core (13) and a tension spring (6). The slotted friction plate servo brake shoe group has the advantages of high braking force and capacity of preventing locking.
Description
Technical field:
The present invention's friction plate servo brake shoe piece group of slotting relates to electric motor car servo brake shoe piece group field.
Background technique:
The friction plate of its both sides of hoof piece group of using on the general battery-operated motor cycle servant brake is level and smooth evagination arc-shaped surface, the friction plate of both sides rubs mutually with the inwall of electric motor car servant brake fuse-box when the cyclist brakes, make the fuse-box braking that is connected on the axletree, thereby realize braking to the electric motor car axletree, but when the cyclist brakes, locking taking place sometimes and brake hypodynamic phenomenon, thereby can not brake to electric motor car reliably.
Summary of the invention:
The locking of when brake the purpose of this invention is to provide a kind of fluting friction plate servo brake shoe piece group, promptly on the friction plate of electric motor car servo brake shoe piece group both sides, has groove, in case can improve the braking force of brake simultaneously again.
A kind of fluting friction plate servo brake shoe piece group, fluting friction plate servo brake shoe piece group is by right shoe plate, left shoe plate, contact pin, tab rivet, extension spring, right shoe plate fixed plate, left shoe plate fixed plate, right friction plate, left friction plate and decide core and form, riveted joint has contact pin on right shoe plate, be embedded with right shoe plate fixed plate, on right shoe plate fixed plate, right friction plate be housed; On left shoe plate, be embedded with left shoe plate fixed plate, on left shoe plate fixed plate, left friction plate be housed; Have some inner groovies on right friction plate and left friction plate, right shoe plate and left shoe plate are by deciding core and extension spring links together.
The friction plate of general electric motor car servo brake shoe piece group both sides is the outer convex arc surface of circular arc, and arc surface is the surface of whole smooth, and its shortcoming is an easy locking servant brake brake disc when brake, simultaneously, braking force is strong inadequately during brake, therefore, should make improvements design to left and right friction plate.
The present invention was having some inner groovies on original left and right Friction Disk Surface in the past, these inner groovies can be various geometric figure, as cross one another inner groovy, mutually the inner groovy of oblique parallel or its are projected as the straight line inner groovy that is parallel to each other etc., in a word, its objective is the braking force that increases between friction plate and the electric motor car servant brake brake disc inwall, locking in the time of can preventing to brake simultaneously.
The slot structure of friction plate servo brake shoe piece group of the present invention is: right shoe plate and left shoe plate be by deciding core and extension spring links together, and on right shoe plate and left shoe plate respectively punching press stiffening rib is arranged, on right shoe plate, contact pin is arranged by rivet; On left and right shoe plate outer rim, respectively be embedded with left shoe plate fixed plate and right shoe plate fixed plate, left friction plate and right friction plate respectively are housed on left and right shoe plate fixed plate.
Slot friction plate servo brake shoe piece group advantage of the present invention is a braking force when having improved the brake of electric motor car servant brake, but and anti-lock.
Description of drawings:
Fig. 1: the fluting friction plate servo brake shoe piece group 1 main schematic representation of looking.
Fig. 2: schematic representation is looked on a left side that has intersection inner groovy 12 on the left friction plate 11 of fluting friction plate servo brake shoe piece group 1.
