From, and by the operation of car running computer control second piston cylinder body, when Vehicle Speed is less than 80 kilometer per hours, the
Two piston/cylinders do not enable in brake process, only use first piston cylinder body and carry out brake, are more than 80 in running speed
Kilometer per hour when, second piston cylinder body is enabled in brake, is greatly reduced braking distance, is prevented the generation of accident, and first is living
Piston limiting device purpose is arranged on the cylinder wall of plug cylinder body and second piston cylinder body to be to pass through when replacing brake block
Piston limiting device prevents the exposing of piston, and hydraulic oil is caused to reduce, and carries out to prevent problem on oil liquid pipeline secondary
It prevents, electromagnetism occluding device is set, prevent the case where keeping off brake pedal when personnel replace brake block, first piston cylinder body
It is identical as second piston housing structure.
Preferably, the piston limiting device includes arc card, and arc card rear end connects bolt, the bolt-through
It, can be by the arc inlay card in the groove by the bolt moving in rotation in the first piston outer wall of cylinder block；?
In piston limiting device due to piston be cylindrical body, limiting device front end be with the intermeshing arc card of cylindrical body, convenient for
Preferably seized piston when can be manually rotated advance, prevents piston from deviating from, when arc is stuck in unused, is mutually nibbled with cylinder body
It closes, will not influence the movement of piston, and in working condition, pistion recess is to the not position of arc card, only in more sliding brake
When vehicle piece, personnel dismantle brake block, and using manually piston is pushed into, pistion recess enters piston cylinder, is caught in work using arc card
It fills in groove.
Preferably, sealing ring, the arc angle of the arc card and described first are installed at the border of the bolt front end
Piston/cylinder arc angle is identical, prevents oil leak when rotating bolt and advancing and uses sealing ring.
Preferably, the electromagnetism occluding device includes touch switch and electromagnetic valve body, and the touch switch is installed on described
Bolt side is provided with pit on the bolt, and the contact on the touch switch and the pit are intermeshed, the bolt
The contact is touched when moving in rotation forward, the electromagnetic valve body is controlled by the touch switch；To prevent in hydraulic oil pipe
Oil liquid continue ejector ram cylinder body and cause Remedy for Piston Damage, electromagnetism occluding device is set, using touch switch and electromagnetic valve body into
Row blocks, and touch switch setting can trigger touch switch by the advance of bolt, to complete electromagnetic valve body in bolt side
It closes.
Preferably, the first brake piece and second brake block include steel plate and friction material layer, the friction
The component and its parts by weight of material layer are as follows: 2~10 parts of cashew nut oil modified alkyd resin, 2~12 parts of hydrogenated nitrile-butadiene rubber, carbonization
