Description
Technical field
The utility model relates to a kind of brake assembly that is used on the tricycle, particularly a kind of dual fail-safe brake assembly.
Background technique
The break of tricycle is made up of brake disc and brake shoe assembly two large divisions, and two braking shoe plate assemblies are installed on the brake disc relatively, is respectively equipped with friction plate on the two braking shoe plate assemblies; One end of two braking shoe plate assemblies is hinged, and the other end of two brake shoe assemblies is established brake pump, between the two braking shoe plate assemblies bracer and returning pull-spring is set; The oil nozzle of brake pump is connected with master cylinder; Brake pump pump oil is given in the brake that tramps with one's feet, and realizes separately braking of brake shoe assembly through brake pump.But when parking or Emergency braking,, be prone to error owing to have only a kind of brake modes.Therefore, people hope on the brake shoe assembly, to set up a parking brake again, and still, because existing bracer is straight, during parking brake pulling torque arm, bracer can disturb torque arm, thereby makes that brake is not in place.Therefore, seek a kind of dual fail-safe brake assembly that can adopt parking brake can adopt service brake and parking brake can not be disturbed again and become the present pursuing target of people.
The model utility content
The utility model technical problem to be solved is to provide a kind of not only can adopt parking brake, but also can adopt the dual fail-safe brake assembly of service brake.
The technological scheme of the utility model is following: a kind of dual fail-safe brake assembly; Comprise brake disc and brake pump, a pair of brake shoe assembly is installed in the front of brake disc relatively, establishes returning pull-spring between two brake shoe assemblies; Said brake pump is installed in the front of brake disc; The adjusting bolt is established at the two ends of said brake pump, and an end of two brake shoe assemblies is separately fixed on the adjusting bolt at brake pump two ends, is provided with bracer between the interior tendons of beef, mutton or pork of two brake shoe assemblies; The middle part of this bracer is bent upwards into convex surface; The two ends of said bracer are separately fixed on the interior tendons of beef, mutton or pork of brake shoe assembly, and the back side of the plate face of the interior tendons of beef, mutton or pork of one of them brake shoe assembly is provided with torque arm, and an end of this torque arm is fixed on the interior tendons of beef, mutton or pork of this brake shoe assembly near brake pump through the torque arm pin.
Adopt technique scheme, brake pump still adopts existing service brake brake pump, does not do at this and gives unnecessary details.Establish torque arm on a brake shoe assembly therein, torque arm connection hand braking pull string, pulling torque arm; The transmission bracer makes the brake shoe assembly expand outwardly, with separating of whole brake shoe assembly; Realize brake, bracer bends to convex surface, like this in manual brake; Bracer can not disturb torque arm, and dynamics is bigger during braking, when descending, can both realize braking.
In technique scheme: fix more reliably in order to make torque arm, firmly, thereby make braking strength bigger, safer, be provided with packing ring and cotter pin between the front of the plate face of the said interior tendons of beef, mutton or pork and the torque arm pin.
In technique scheme: the back side of said brake disc is provided with oblique cover, and this tiltedly overlaps near torque arm.Tiltedly cover is used for the backguy of fixedly torque arm, plays the effect that orientation is led the position.
Beneficial effect: the utility model is reasonable in design, simple in structure, implement easily, and is easy to use, adopts the dual fail-safe brake, makes that brake is safer, reliable.
