Description
Technical field
The utility model relates to mechanical braking technical field, particularly a kind of compensation brake equipment.
Background technology
The drg major part that current domestic full size vehicle uses is all pneumatic brake device, compression air brake must adopt the devices such as air compressor, gas tank, brake activation valve, the generation of air pressure and remove all slower in pipeline, effect is longer delay time, and in full size vehicle when braking, is larger to the wearing and tearing of parts, often there is the situation of brake failure, cause more serious traffic accident.
Utility model content
The technical problems to be solved in the utility model has been to provide a kind of compensation brake equipment that Emergency Negative Thrust is provided.
The technical solution of the utility model is as follows:
A kind of compensation brake equipment, comprise and adjust arm, camshaft, crossbeam, drive axle and brake shoes, described camshaft is connected with brake shoes, left end outside at described crossbeam is disposed with distributing box, motor and electric-controlled switch from front to back, and described distributing box, motor and electric-controlled switch are connected successively; On described vertical beam, be provided with the stay bearing plate stretching out backward, the rear end upper panel face level of this stay bearing plate is provided with hydraulic actuating cylinder, the front end of described hydraulic actuating cylinder is provided with push rod, the front end of push rod is connected with the upper end of compensation adjustment arm, the rear end of hydraulic actuating cylinder is connected with distributing box by oil pipe, is also provided with the groove of upper and lower opening at the horizontal plate face of described stay bearing plate front end; On described camshaft, be installed with compensation adjustment arm, described compensation adjustment arm be arranged in parallel on camshaft with adjusting arm, and the top of this compensation adjustment arm is passed this groove and is connected with push rod.
Adopt above structure, on camshaft, add a compensation adjustment arm, this compensation adjustment arm is also connected with hydraulic actuating cylinder, and the pressure size of described hydraulic actuating cylinder regulates by distributing box, the power of distributing box obtains by motor, and electric-controlled switch is controlled the opening and closing of motor; In the time of the original brake failure of vehicle, open electric-controlled switch starter motor, motor provides power that hydraulic oil is flowed to distributing box, distributing box is passed to hydraulic actuating cylinder according to the parameter of adjusting pressure, hydraulic actuating cylinder running promotes push rod later, push rod drives compensation adjustment arm to rotate again, also drive camshaft to rotate and strut brake shoes simultaneously, reach the effect of emergency braking with this, entirety assembling is relatively independent, the each parts of automobile are not produced to interference, can effectively prevent the traffic accident occurring because of brake failure.
According to the service condition of vehicle, in order not affect the work of original drg, avoid interfering with each other, as preferably, the front end of described push rod is provided with one section of opening forward and the chute of up/down perforation, and the top of described compensation adjustment arm is stretched in this chute.
Beneficial effect: the utility model adds a compensation adjustment arm on camshaft, this compensation adjustment arm drives camshaft to rotate the effect that reaches emergency braking with this by automatically controlled hydraulic actuating cylinder, simple in structure, entirety assembling is relatively independent, do not take too many space, the each parts of automobile are not produced to interference, can effectively prevent the traffic accident occurring because of brake failure.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to view.
