Abstract
The utility model discloses a front-tightening type double-cavity booster. Dynamic stability of the booster in the working process is improved, and the assembly between the booster and a master cylinder is simplified. According to the technical scheme, the front-tightening type double-cavity booster comprises a front shell, a rear shell, a front shell bolt, O-shaped rings, pressing blocks, a guide sleeve, a supporting bowl and a connecting threaded rod, wherein a penetrating structure is formed by the guide sleeve, the O-shaped rings, the pressing blocks and the front shell of the booster, and the other penetrating structure is formed by the guide sleeve, the O-shaped rings, the pressing blocks and the rear shell of the booster.
Description
Technical field
The utility model relates to a kind of servo-unit, relates in particular to the two-chamber servo-unit of tightening formula assembling before a kind of.
Background technology
Fig. 1 shows traditional type two-chamber servo-unit, and Fig. 2 shows and runs through rod-type list chamber servo-unit.Traditional type two-chamber servo-unit elastic deformation shown in Fig. 1 is larger, and dynamic stability during work is not high.And the operative employee of running through rod-type list chamber servo-unit shown in Fig. 2 will complete at operator's compartment the assembling of servo-unit and front coaming plate, thereby be difficult for assembling and keeping in repair.
Utility model content
The purpose of this utility model is to provide before a kind of tightens formula two-chamber servo-unit, and the dynamic stability while improving servo-unit work, has simplified the assembling of servo-unit and master cylinder.
The technical solution of the utility model is: the utility model has disclosed before a kind of and tightened formula two-chamber servo-unit, comprise front case, rear housing, front case bolt, O type circle, briquetting, pilot sleeve, support bowl, connecting screw rod, wherein pilot sleeve, O type circle, briquetting and support bowl run through structure with front case and the rear housing formation of servo-unit respectively.
According to an embodiment who tightens formula two-chamber servo-unit before of the present utility model, connecting screw rod is arranged in pilot sleeve with the state moving freely.
The utility model contrast prior art has following beneficial effect: before of the present utility model, tighten formula two-chamber servo-unit has increased the supporting construction parts such as connecting screw rod and pilot sleeve on the basis of traditional type servo-unit.With respect to running through bar type structure, the front formula two-chamber servo-unit of tightening has increased pilot sleeve and O type circle.Because master cylinder flange is arranged on front case bolt, so this connecting screw rod can be independent of master cylinder assembling.Before tighten operative employee and starting cabin just can realize the assembling of servo-unit and fire-proof plate, easily assembling and maintenance.
Accompanying drawing explanation
Fig. 1 shows the structure of traditional type two-chamber servo-unit.
Fig. 2 shows the structure that runs through rod-type list chamber servo-unit.
Fig. 3 shows the structure of tightening the preferred embodiment of formula two-chamber servo-unit before of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 3 shows the structure of tightening the preferred embodiment of formula two-chamber servo-unit before of the present utility model, refer to Fig. 3, before the present embodiment, tightening formula two-chamber servo-unit comprises front case 5, rear housing 6, front case bolt 7, O type circle 4, briquetting 5, pilot sleeve 2, supports bowl 3, connecting screw rod 1, wherein pilot sleeve 2, O type circle 4, briquetting 5 and support bowl 3 run through structure with front case 5 and rear housing 6 formation of servo-unit respectively, and connecting screw rod 1 is arranged in pilot sleeve 2 with the state moving freely.Because master cylinder flange is arranged on front case bolt 7, so this connecting screw rod can be independent of master cylinder assembling.
With respect to the traditional type two-chamber servo-unit shown in Fig. 1, the inner pilot sleeve 2 that increases of servo-unit of the present utility model, servo-unit with in car load fitting process, by two overbolts, be connected with fire-proof plate, in braking procedure, stress point acts on overbolt completely, thereby make servo-unit elastic deformation very little, dynamic stability during servo-unit work improves, and for car load, pedal sense is good.
With respect to running through rod-type list chamber servo-unit shown in Fig. 2, before servo-unit of the present utility model makes, tighten operative employee and starting cabin just can realize servo-unit and fire-proof plate assembling, easily assembling and maintenance.
Above-described embodiment is to provide to those of ordinary skills and realizes and use of the present utility model; those of ordinary skills can be in the situation that not departing from invention thought of the present utility model; above-described embodiment is made to various modifications or variation; thereby protection domain of the present utility model do not limit by above-described embodiment, and it should be the maximum range that meets the inventive features that claims mention.
Claims (2)
1. tighten formula two-chamber servo-unit before one kind, it is characterized in that, comprise front case, rear housing, front case bolt, O type circle, briquetting, pilot sleeve, support bowl, connecting screw rod, wherein pilot sleeve, O type circle, briquetting and support bowl run through structure with front case and the rear housing formation of servo-unit respectively.
2. before according to claim 1, tighten formula two-chamber servo-unit, it is characterized in that, connecting screw rod is arranged in pilot sleeve with the state moving freely.
