Can, therefore, it is necessary to which the emptying characteristic to parking brake is furtherd investigate, to guarantee that flame proof rubber tyre vehicle loses in service brake
Still there is reliable brake safe performance in the case where effect.But the country is to flame proof rubber tyre vehicle in terms of service brake at present
Research it is more, and the research in terms of parking braking is actually rare, lacks a kind of reliable vehicle stop brake mechanism.
Utility model content
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide a kind of for flame proof rubber tyre vehicle
Vehicle stop brake mechanism, the structure emptying process is very fast, ensure that the sensitivity of braking, and braking effect is good.
A kind of parking system for flame proof rubber tyre vehicle that in order to achieve the above purposes, the technical solution adopted by the utility model is:
Dynamic device structure, includes shaft, first end cover, shell, second end cover, piston, disc spring, platen, friction plate；The shaft is to set
It is equipped with the cylindrical structure of the multistage shaft shoulder, first end cover and second end cover are set with outside the shaft；The first end cover and second end
Shell is connected between lid, which passes through flange bolt respectively and connect with first end cover, second end cover, and housing central section
It is provided with a circle convex；The shaft is outer to be set with L shape piston adjacent to second end cover, which is bonded case inside face simultaneously
With shell convex medial surface, and piston is fluted to setting at second end cover；Recessed position is opened in middle part on the shell side
Equipped with hydraulic oil-passing port, which is connected between shell and piston；It is provided with disc spring in the pistion recess, the dish
Spring is two groups of iterative dished springs, is connected in parallel between second end cover and piston；The piston is logical to the end in first end cover direction
It crosses and has been bolted platen, which is disc structure, and platen lateral surface is bonded case inside face；The platen, shell, first
Friction plate is installed in space between end cap and shaft.
Preferably, the friction plate is divided into two parts, a part is fixedly connected by spline with shaft, and another part is logical
It crosses spline to be fixedly connected with the casing, interlaced arrangement between two parts friction plate, and be separated by certain interval between two parts friction plate.
Preferably, being all provided between the first end cover and shell, between second end cover and shell, between shell and piston
It is equipped with seal configuration.
The beneficial effects of the utility model are: the structure emptying process is very fast, the sensitivity of braking ensure that, and make
It is dynamic to work well.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is vehicle stop brake mechanism schematic diagram.
Wherein: 1 is shaft, and 2 be first end cover, and 3 be shell, and 31 be hydraulic oil-passing port, and 4 be second end cover, and 5 be piston, 6
It is platen for disc spring, 7,8 be friction plate.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown, a kind of vehicle stop brake mechanism for flame proof rubber tyre vehicle, includes shaft 1, first end cover 2, shell
Body 3, second end cover 4, piston 5, disc spring 6, platen 7, friction plate 8；The shaft 1 is the cylindrical structure for being provided with the multistage shaft shoulder,
First end cover 2 and second end cover 4 are set with outside the shaft 1；It is connected with shell 3 between the first end cover 2 and second end cover 4,
3 both ends of shell pass through flange bolt respectively and connect with first end cover 2, second end cover 4, and are provided in a circle in the middle part of shell 3
It is convex；The shaft 1 is outer to be set with L shape piston 5 adjacent to second end cover 4, which is bonded 3 medial surface of shell and shell 3 simultaneously
Convex medial surface, and piston 5 is fluted to setting at second end cover 4；Recessed position offers in middle part on 3 side of shell
Hydraulic oil-passing port 31, the hydraulic oil-passing port 31 are connected between shell 3 and piston 5；It is provided with disc spring 6 in 5 groove of piston,
The disc spring 6 is two groups of iterative dished springs, is connected in parallel between second end cover 4 and piston 5；The piston 5 is to 2 direction of first end cover
End platen 7 has been bolted, the platen 7 be disc structure, 7 lateral surface of platen be bonded 3 medial surface of shell；The pressure
Friction plate 8 is installed in space between disk 7, shell 3, first end cover 2 and shaft 1.
When it is implemented, the friction plate 8 divides for two parts, a part of to be fixedly connected by spline with shaft 1, another portion
Divide and is fixedly connected by spline with shell 3, interlaced arrangement between two parts friction plate 8, and it is separated by one between two parts friction plate 8
Fixed gap.
When it is implemented, between the first end cover 2 and shell 3, between second end cover 4 and shell 3, shell 3 and piston 5
Between be provided with seal configuration.
When practical operation, when flame proof rubber tyre vehicle is in driving status, certain pressure is full of in parking brake plunger shaft
Oil liquid, 5 left side of piston abuts 4 right side of second end cover, and plunger shaft volume is maximum at this time, and friction plate 8 is completely separated, and brakes
It releases completely.When flame proof rubber tyre vehicle needs emergency braking or stopping brake, by the reversal valve in manipulation hydraulic circuit, make to make
Actuator piston chamber is communicated with fuel tank, then piston 5 will move right under the action of disc spring 6, piston cavity pressure oil liquid is squeezed
Out, fuel tank is flowed back to by reversal valve, this stage, plunger shaft volume gradually becomes smaller.After piston 5 is run to the right to certain position,
Platen 7 starts extrusion friction piece 8, holds friction plate 8 mutually tightly and rubs, generates braking torque.When needing to release braking,
It is same so that extraneous high pressure oil is flowed to brake plunger chamber by reversal valve by manipulation reversal valve, it is living under oil liquid pressure effect
Plug 5 overcomes acting force of the spring to move downward, and until with 4 right end face contact of second end cover, brakes and releases completely.
