Background technology
Automobile drum brake is to be opened by brake-shoe by hydraulic wheel cylinder, is pressed on brake drum, real to frictionally
Existing slowing-down brake.Drum brake also can double as parking brake use, compared with disk brake, the use of friction plate simultaneously
Life-span is longer, vehicle maintenance low cost.The mode of braking that the most current economy car rouses after all using shroud.Chinese patent
Disclosing a kind of brake shoe assembly (Authorization Notice No.: CN 201963775U), it includes the brake-shoe welding group of semicircle drum type
Part, the outer circumferential of brake-shoe weld assembly is provided with brake lining, and brake-shoe weld assembly is provided with wear indicator, and abrasion refers to
Show that one end of device is concordant with the limit of wear position of brake lining in suspension shape and its end, the wear indicator other end and automobile
The sensor of ECU control system connects；Wear indicator includes straight bar section, and one end of straight bar section is revealed in brake-shoe weld assembly
Outer end and concordant with the limit of wear position of brake lining, the other end of straight bar section is bending and its end head is welded on
On brake-shoe weld assembly；The kink of wear indicator in " 5 " font, the afterbody of kink is connected with straight bar section, head with
The contour line of brake-shoe weld assembly is concordant；Wear indicator is that the stainless steel material bending of bar tabular forms.But this system
Dynamic hoof assembly torque arm is operationally worn and torn more serious, and energy-saving poor, the connection of friction plate is relatively weak, easily from hoof face
Come off, and the friction effect of friction plate is poor, so that service life is relatively low.
Utility model content
This utility model is to provide a kind of electric mini-car brake shoe assembly, and it mainly solves existing for prior art
Brake shoe assembly torque arm operationally wear and tear more serious, energy-saving poor, the connection of friction plate is relatively weak, easily from hoof
Come off on face, and the friction effect of friction plate is poor, so that the technical problem of relatively low grade in service life.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
Electric mini-car brake shoe assembly of the present utility model, including the neck hoof of circular arc and from hoof, described neck hoof
With on hoof, be designed with the animal limb tendons, the edge of the animal limb tendons is provided with the hoof face vertically set up, and the outer surface in hoof face is provided with friction plate, from hoof hoof
The one side of muscle has torque arm by torque arm rivet interlacement, and on the neck hoof animal limb tendons, cross-under has straight pin, is provided with torque arm packing ring at torque arm rivet,
The outer surface of straight pin has dashpot, and the bottom surface of dashpot is angularly disposed circular arc.Outer surface at straight pin is offered
Dashpot, so that plectrum can play the effect of buffering when installing plectrum, prevents it excessive with straight pin contact surface,
Thus cause serious wear, service life is too short, serves energy-saving and cost-reducing effect.
As preferably, described hoof face is provided with the support member of some I shapes, and support member is embedded in friction plate.Support
A part part is fixed on hoof face, and another part is embedded in friction plate, and such friction plate can tively firm be fixed on hoof
On face.
As preferably, in described friction plate, it is provided with dovetail groove, is provided with calendering block in dovetail groove, at the bottom of calendering block and dovetail groove
Portion is provided with gap.Calendering block can carry out activity in dovetail groove, and operationally, calendering block can be calendered such friction plate,
Fill up gap, such that it is able to improve the adaptability of friction plate.
As preferably, the side of described torque arm is provided with keeper, and keeper is formed by the part bending of torque arm.Pass through
Within keeper can ensure that torque arm operationally can be controlled in stroke range, thus reach spacing effect.Keeper
Directly bend from torque arm and form, so that process more convenient.
Therefore, this utility model is by dashpot so that the abrasion of straight pin is less, and energy conservation and consumption reduction effects is preferable, profit
With support member so that friction plate connects ground more firmly, the friction effect of friction plate is preferable simultaneously, and service life is longer, knot
Structure is simple, rationally.
