Parking brake durability test apparatus.
Background technology
Vehicle hand brake equipment is essential a kind of auxiliary device on automobile, and the type of parking brake can be divided into mechanical parking brake
With electronics parking brake, the major advantage of mechanical parking brake is exactly at low cost, and using flexible, reliability is higher, electronics parking brake it is main excellent
Point is shape simple and beautiful, and easy to use, electronics parking brake is common configuration on the vehicle of middle and high end.From current automobile by
It is limited in cost, the automobile application of most of low and middle-end is still mechanical hand brake device.Hand brake device is mainly drawn by handle, steel wire
The components such as line, returning spring form.
The profession address of parking brake is auxiliary brake, different from the principle of brake, is connected to using steel wire pull line
On brake-shoe, to be braked to car.Specifically, parking brake, for kart, some designs are after gearbox, with biography
There is a brake drum (also having disc type brake) in the place of moving axis connection, it is pushed using a hydraulic pressure auxiliary cylinders after pulling parking brake
The total cylinder movement of the following hydraulic pressure of vehicle, then drives air valve, brake and transmission shaft, if it is common card after completing brake and transmission shaft
Vehicle is then pulled using the cable wire of hand brake lever to realize long-term immobilization, is then used electric control if it is more high-grade truck, is worked as hand
When brake intervention work, also start simultaneously there are one motor, motor will tense cable wire simultaneously after the completion of air damping
And it locks.
The effect of parking brake clearly, when if usually stopping is forgotten to pull the hand brake, and vehicle is susceptible to and slips, and consequence is very
Seriously.It all should pull-up parking brake when uphill starting, parking, waiting traffic lights.
Parking brake, which is used for a long time, can make steel wire generate plastic deformation, since this deformation is expendable, so long-term
Using the brake fade that can make parking brake, the braking distance of parking brake can also increase.With the matching used also reply bullet of parking brake
Spring, when parking brake operation, pull-up parking brake, spring can be elongated under a stretching force, and spring-return is former when parking brake is decontroled
It is long, spring is used for a long time and also will produce corresponding deformation.Since parking brake is so important, application is so frequent, so parking brake is going out
It is needed before factory by a series of experimental test, most important here is exactly endurance test, how easily to be carried out to parking brake
Durability test is exactly the problem put in face of design engineer, i.e., how by a kind of device come simulate parking brake reality
The course of work on border is most important.
