Description
Technical field
The utility model relates to clutch detector spare, particularly relates to a kind of hydraulic booster having brake master cylinder assembly.
Background technology
At present, what the N2 class goods carrying vehicle of domestic gross weight more than 6 tons mostly adopted is air braking system, and generally than the liquid braking roughly, poor controllability and power-assisted are limited in the gas braking.And abroad N2, N3 class part car brake system have adopted hydraulic booster system, can satisfy different clients to the requirement of handling, the high pressure oil power-assisted that hydraulic booster system can adopt special-purpose oil pump to provide also can share the high pressure oil power-assisted that power steerig pump provides with steering swivel system.Simultaneously, after adopting hydraulic booster system, the corresponding parts such as the air chamber that Air compressor, dryer, the braking of various gas are used with nylon tube, steel pipe and pneumatic brake with valve (protecting valve, rapid release valve, relay valve etc. such as unloading valve, four), a large amount of gas braking, support, adjustment arm have been saved.Compare with air braking system, the hydraulic booster system part is few, cost is low, can save axle assembly and car load time of setting up simultaneously, enhances productivity.
Therefore, domestic main engine plants are also developing the great tonnage hydraulic abrupt deceleration vehicle successively.But because the most domestic goods carrying vehicle is to adopt forward control cab, and on the axial dimension of hydraulic booster having brake master cylinder assembly in the market all than the total growth of vacuum booster with master cylinder, so hydraulic booster having brake master cylinder assembly is difficult to be arranged in the operator's compartment.Some main engine plants is for head it off, with hydraulic booster having brake master cylinder assembly 90-degree rotation (parallel with front wall) or be placed on the chassis frame, then adopts complicated linkage mechanism to drive, and this not only assembles difficulty, and affects driving efficiency.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, to provide a kind of axial dimension short and hydraulic booster having brake master cylinder assembly simple in structure.
In order to realize above purpose, a kind of hydraulic booster having brake master cylinder assembly that the utility model provides, comprise hydraulic booster and master brake cylinder, described master brake cylinder comprises cylinder body, leather cup, first piston assembly and the second piston assembly, described first piston assembly and the second piston assembly are installed in the described cylinder body successively, and described leather cup is arranged on the inwall of described cylinder body.Because the leather cup of existing assembly is arranged on the piston portion of piston assembly, so limited length that piston portion stretches out cylinder body during work, this assembly is by being arranged in leather cup on the inwall of cylinder body, like this, the piston portion of described first piston assembly can stretch out described cylinder body more longways during the real work of this assembly, thereby can shorten the axial length of described cylinder body, the axial length of described master brake cylinder is shortened, shorten the whole axial dimension of this assembly.
In such scheme, the inwall of described cylinder body is provided with the mounting groove that matches with described leather cup, and described leather cup is installed in the described mounting groove.Certainly, also can adopt other mounting meanss.
In such scheme, described first piston assembly comprises first piston and with the first spring perch of spring, is provided with the first holding tank in the described first piston that described the first spring perch is installed in the first holding tank of described first piston by screw.By in piston assembly, adding holding tank, like this, can shorten the axial length of piston assembly, thereby further shorten the axial length of described master brake cylinder, shorten the whole axial dimension of this assembly.
In such scheme, described the second piston assembly comprises the second piston and with the second spring perch of spring, is provided with the second holding tank in described the second piston that described the second spring perch is installed in the second holding tank of described the second piston by screw.By in piston assembly, adding holding tank, like this, can shorten the axial length of piston assembly, thereby further shorten the axial length of described master brake cylinder, shorten the whole axial dimension of this assembly.
In such scheme, described the first spring perch is installed on described the second piston, and described first piston links to each other with the push rod of described hydraulic booster.
The utility model on the one hand, by leather cup being arranged on the inwall of cylinder body, like this, the piston portion of described first piston assembly can stretch out described cylinder body more longways during the real work of this assembly, thereby can shorten the axial length of described cylinder body, shorten the whole axial dimension of this assembly; On the other hand, by in piston assembly, adding holding tank, like this, can shorten the axial length of piston assembly, thereby further shorten the axial length of described master brake cylinder, shorten the whole axial dimension of this assembly.
The utility model is compared with the prior art, and shows that fully its preceence is: axial dimension is short, simple in structure and easy to use etc.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of master brake cylinder.
Among the figure: hydraulic booster 1, master brake cylinder 2, leather cup 3, first piston assembly 4, first piston 4a, the first spring perch 4b, the first holding tank 4c, the second piston assembly 5, the second piston 5a, the second spring perch 5b, the second holding tank 5c, mounting groove 6, cylinder body 7.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
Present embodiment provides a kind of hydraulic booster having brake master cylinder assembly, comprise hydraulic booster 1 and master brake cylinder 2, described master brake cylinder 2 comprises cylinder body 7, leather cup 3, first piston assembly 4 and the second piston assembly 5, described first piston assembly 4 and the second piston assembly 5 are installed in the described cylinder body 7 successively, and described leather cup 3 is arranged on the inwall of described cylinder body 7.Like this, the piston portion of described first piston assembly 4 can stretch out described cylinder body 7 more longways during the real work of this assembly, thereby can shorten the axial length of described cylinder body 7, shortens the whole axial dimension of this assembly.The inwall of described cylinder body 7 is provided with the mounting groove 6 that matches with described leather cup 3, and described leather cup 3 is installed in the described mounting groove 6.Certainly, also can adopt other mounting meanss.
