Description
Technical field
The utility model belongs to master cylinder assembly technical field, particularly relates to a kind of brake master cylinder assembly.
Background technology
Master brake cylinder utilizes the parts power put on pedal being changed into brake fluid pressure in motor vehicle braking system.As shown in Figure 1, first piston assembly 2, second piston assembly 3 in the master cylinder body 1 of conventional brake master cylinder assembly is connected with the first spring bearing housing 6 stroke traveller 4 by first piston 5, during work, the first spring 7 compresses, and first piston 5 moves with stroke traveller 4 and the first spring bearing housing 6; Play defect to be: stability is not high, cost is also higher.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and the brake master cylinder assembly a kind of good stability being provided, reducing costs.
The purpose of this utility model has been come by following technical solution, comprise master cylinder body and two piston assemblies being positioned at master cylinder body, i.e. the 3rd piston assembly and the 4th piston assembly, the 3rd described piston assembly contacts with the end wall of master cylinder body, on the groove that the piston that 4th piston assembly is embedded in the 3rd piston assembly by spring bearing housing is offered, namely the 3rd piston assembly is connected with the 4th piston assembly; Primary cup, first pair of leather cup is placed with between the 3rd described piston assembly and the sidewall of master cylinder body, be placed with second pair of leather cup between the 4th described piston assembly and the sidewall of master cylinder body, master cylinder body is provided with liquid inlet joint assembly, elastic cylindrical pin and feed flow seal ring.
As preferably, two described piston assemblies are made up of spring bearing housing, piston, spring, described spring bearing housing is cylindrical Openworks shape, one end of this spring bearing housing to be inserted in inner chamber that piston is provided with and spacing fixing, is folded with spring between the interior cavity wall that the other end inwall of this spring bearing housing and piston are provided with.
The beneficial effects of the utility model are: the working stability improving master brake cylinder, reduce the manufacture of brake master cylinder assembly, assembly cost, improve efficiency of assembling.
Accompanying drawing explanation
Fig. 1 is existing brake master cylinder assembly structural representation.
Fig. 2 is brake master cylinder assembly structural representation of the present utility model.
Label in accompanying drawing is respectively: 1, master cylinder body; 2, first piston assembly; 3, the second piston assembly; 4, stroke traveller; 5, first piston; 6, the first spring bearing housing; 7, the first spring; 8, the 3rd piston assembly; 9, the 4th piston assembly; 10, the second spring bearing housing; 11, the second piston; 12, primary cup; 13, first pair of leather cup; 14, second pair of leather cup; 15, liquid inlet joint assembly; 16, elastic cylindrical pin; 17, feed flow seal ring; 18, the second spring; 111, groove; 112, inner chamber.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed introduction is done to the utility model: as shown in Figure 2, the utility model comprises master cylinder body 1 and is positioned at two piston assemblies of master cylinder body 1, i.e. the 3rd piston assembly 8 and the 4th piston assembly 9, the 3rd described piston assembly 8 contacts with the end wall of master cylinder body 1, on the groove 111 that the second piston 11 that 4th piston assembly 9 is embedded in the 3rd piston assembly 8 by the second spring bearing housing 10 is offered, namely the 3rd piston assembly 8 is connected with the 4th piston assembly 9; Primary cup 12, first pair of leather cup 13 is placed with between the 3rd described piston assembly 8 and the sidewall of master cylinder body 1, be placed with second pair of leather cup 14 between the 4th described piston assembly 9 and the sidewall of master cylinder body 1, master cylinder body 1 is provided with liquid inlet joint assembly 15, elastic cylindrical pin 16 and feed flow seal ring 17.
Two described piston assemblies are made up of the second spring bearing housing 10, second piston 11, second spring 18, the second described spring bearing housing 10 is cylindrical Openworks shape, one end of this second spring bearing housing 10 to be inserted in inner chamber 112 that the second piston 11 is provided with and spacing fixing, is folded with the second spring 18 between inner chamber 112 inwall that the other end inwall of this second spring bearing housing 10 and the second piston 11 are provided with.
During brake master cylinder assembly of the present utility model work the second piston 11 directly with the second spring bearing housing 10 relative movement, its working stability is better than conventional brake master cylinder assembly first piston 5 with stroke traveller 4 and the first spring bearing housing 6 relative movement.Reduce brake master cylinder assembly inner body quantity simultaneously, reduce costs, improve efficiency of assembling.
The utility model is not limited to above-mentioned embodiment; no matter do any change on its shape or material are formed; every employing structure design provided by the utility model, is all one distortion of the present utility model, all should thinks within the utility model protection domain.
