Replace original through-rod structure through bolt 6 and hollow sleeve 5, brake master cylinder body 1 passes through nut 10 locking on sleeve 5, and use "O" type sealing washer 9 to seal between brake master cylinder body 1 and sleeve 5, it is spacing through sleeve 5's hexagonal flange face between sleeve 5 and back casing 4, in order to assemble the peculiar uide bushing 12 of intelligent booster, prevent changeing layer board 13 and spindle unit 3, it is spacing not to adopt conventional hexagonal flange face between sleeve 5 and procapsid 2, but adopt the 11 structures of stop collar of components of a whole that can function independently to carry on spacingly, through bolt 6 inserts sleeve 5 and can realize freely horizontal activity in sleeve 5, through still realizing taking out from the master cylinder end. When the whole car is assembled, only one worker inserts through bolt 6 into hollow sleeve 5 in the engine compartment, screws up corresponding bolt and realizes that through bolt 6 and sleeve 5's connection is fixed, and such structure makes single workman just can assemble whole car with intelligent booster, has greatly improved the installation effectiveness and has effectively alleviateed assembly cost.
According to the through bolt type intelligent booster structure provided by the embodiment of the invention, through the arrangement of the through assembly, one end of the sleeve 5 in the through assembly penetrates through the brake main cylinder body 1 and the rear shell 4 and extends outwards to fix the brake main cylinder body 1 and the rear shell 4, the other end penetrates through the front shell 2 and is fixed with the front shell 2, and the through bolt 6 can freely move transversely in the sleeve 5 and can also be pulled out from the main cylinder end, so that when the whole vehicle is assembled, only one worker inserts the through bolt 6 into the hollow sleeve 5 in an engine cabin and screws the corresponding bolt, the intelligent booster can be installed, the installation efficiency of the intelligent booster is greatly improved, and the assembly cost of the intelligent booster is effectively reduced.
In the invention, the original penetrating rod structure is replaced by the penetrating bolt 6 and the hollow sleeve 5, the brake main cylinder body 1 is locked on the sleeve 5 through the nut 10, the O-shaped sealing ring 9 is used for sealing between the brake main cylinder body 1 and the sleeve 5, the sleeve 5 and the rear shell 4 are limited through the hexagonal flange surface of the sleeve 5, in order to assemble the guide sleeve 12, the anti-rotation supporting plate 13 and the spindle assembly 3 which are special for the intelligent booster, the conventional hexagonal flange surface limitation is not adopted between the sleeve 5 and the front shell 2, but a split limiting sleeve 11 structure is adopted for limiting, the penetrating bolt 6 is inserted into the sleeve 5 and can freely move transversely in the sleeve 5, and the penetrating bolt can be drawn out from the main cylinder end. When the whole car is assembled, only one worker inserts through bolt 6 into hollow sleeve 5 in the engine compartment, screws up corresponding bolt and realizes that through bolt 6 and sleeve 5's connection is fixed, and such structure makes single workman just can assemble whole car with intelligent booster, has greatly improved the installation effectiveness and has effectively alleviateed assembly cost.
