Function with middle scram button is more and more important；When construction implement road roller needs engine jerk to brake, tradition is being pressed
Scram button after, the power-off of road roller full car, i.e., stopped using engine braking, however, in real operation, for large-tonnage pressure
The jerk of road machine does not often reach required effect, therefore it needs to complete to stop using operations such as service brake or parking brakings
Machine, but can cause to produce the less efficient phenomenon of jerk again during such operation, so as to reduce road roller security performance；On in view of
State reason, it is proposed that a kind of brake linkage of road roller jerk parking.
The content of the invention
In order to overcome the shortcomings of in background technology, the utility model discloses a kind of braking of road roller jerk parking linkage
Device, described device can effectively shorten braking distance, so as to reach the purpose for improving jerk efficiency and traffic safety.
For achieving the above object, the utility model adopts the following technical scheme that：
A kind of brake linkage of road roller jerk parking, described device include scram button 1, manual parking braking
Handle 2, source of the gas 3, magnetic valve 4, parking braking air chamber 5, A gas circuits port 6, R gas circuits port 7, P gas circuits port 8 are formed；Described
Scram button 1 and magnetic valve 4 connect by the way that the air-pressure duct for controlling braking is corresponding, the magnetic valve 4 be provided with A gas circuits port 6,
R gas circuits port 7 and the gas circuit port of P gas circuits port 8 three；Described A gas circuits port 6 passes through air-pressure duct and manual parking braking
Handle 2 is corresponding to be connected, and manual parking brake handle grip 2 also passes through the connection corresponding with source of the gas 3 of another air-pressure duct；Described R gas
Road port 7 passes through air-pressure duct connection corresponding with parking braking air chamber 5；Described P gas circuits port 8 passes through air-pressure duct and brake
Clamp the corresponding connection of disk.
Further, described magnetic valve 4 is corresponding positioned at the lower section of scram button 1 and manual parking brake handle grip 2, and simultaneously
Positioned at the top of parking braking air chamber 5.
Further, described A gas circuits port 6 and P gas circuits port 8 are respectively correspondingly arranged in the both sides of magnetic valve 4, described R
Gas circuit port 7 is located at the bottom of magnetic valve 4.
Due to using technical scheme as described above, the utility model has the advantages that：
The brake linkage of road roller jerk parking described in the utility model is not only simple in construction, and cost is cheap, easily
It is easy to operation in installation, and its safety coefficient is also high；Described device is by reasonably designing, using source of the gas as instant
The power of transmission, its need, which presses scram button, can just complete the jerk parking operation of road roller, while can also limit hand
The action of parking brake handle grip is controlled, accordingly reduces the process time of manual operation, so as to not only be effectively accomplished shortening system
Dynamic distance, improves the purpose of jerk efficiency and traffic safety, but also human factor can be avoided to cause to slip in practical operation
The phenomenon on slope occurs；Proved through many experiments, under the conditions of equal speed, the jerk efficiency of described device can be than traditional jerk
The jerk efficiency of button improves 50% or so, and described device can also realize shutdown Braking mode, therefore described device is very
Suitable for promoting and using.
