Description
Technical field
The utility model relates to the auto parts machinery technical field, and especially a kind of being arranged on be used for to drive that brake block unclamps or the device of locking between automobile brake sheet and driving mechanism.
Background technique
Existing braking device, general all pass in and out housing by brake oil and controls piston in housing and put in and stretch out, and the motion of the relative housing of piston makes brake block that the piston exterior edge face drives compress or unclamp the wheel hub of automotive wheel, to play the effect of braking of controlling.Its structure is generally that an inner tubular end is provided with the piston oil seal ring 8 by rubber in the housing 1 of opening a piston 2 is installed, as shown in Figure 1, the exterior edge face of piston 2 connects brake block, housing 1 connects actuating unit and the brake fluid line of vehicle, brake oil enters into the space between the inwall of piston 2 interior edge faces and housing 1 by the brake oilhole 13 that arranges on housing 1, enter interior brake oil 22 pushing pistons 2 of housing 1 to the outer motion of housing 1, the brake block that piston 2 exterior edge faces are driven compresses the wheel hub of automotive wheel; Otherwise brake oil 22 refluxes, and makes piston be retracted into housing 1, and brake block unclamps the wheel hub of wheel.there is a serious problem in the braking device of this spline structure, be that brake oil flows for a long time between the cylinder body outer wall of piston and inner walls, because brake oil is not high-purity, and brake oil easily is subject to the pollution of impurity when Vehicle Driving Cycle, impure brake oil is after braking device uses two to three months, having part sticks on the cylinder body outer wall and inner walls of piston, hindered the relative movement of piston and housing, when brake, due to the pressure that pumps into brake oil, piston still can separate with housing, but when releasing of brake, while being the backflow of brake oil, brake oil sticks together outer cylinder body surrounding and the inner walls of piston, return and housing thoroughly do not close fully to make piston, thereby brake block separates not thoroughly with the wheel hub of wheel, " waiting to stop " state of generation, while making Vehicle Driving Cycle brake block with separate halfway wheel hub and produce friction, wheel hub and brake block heating, heat reaches brake oil, cause that brake oil expands, greatly reduce brake sensitivity, cause running condition bad, reduce the working life of braking device and vehicle related components, and increased the load that travels.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of braking device, it can solve existing braking device brake block when removing brake and separate not thoroughly with hub for vehicle wheel, and brake failure is quick, affects traveling state of vehicle, travel load and braking device short problem in working life.
In order to address the above problem, the technical solution of the utility model is: this braking device comprises the housing of strap brake oilhole and by the piston oil seal ring, is contained in piston in described housing, described piston one end is provided with through hole, this through hole end is towards the sealing end of described housing, described piston cavity is set with inner carrier by the inner carrier oil seal ring, described inner carrier oil seal ring is divided into brake grease chamber and oil chamber with described piston cavity, and an end of described inner carrier stretches out and fixes from the through hole of described piston and the hole of described housing sealing end; The brake oilhole of described housing is communicated with the brake fluid line in described housing, is provided with the oil-feed duct that is connected with brake fluid line in described inner carrier, and the oil outlet in this oil-feed duct is communicated with described brake grease chamber; Described housing is provided with oil-controlling device outward, and the oil duct of this oil-controlling device is communicated with described housing inner chamber.
In technique scheme, more specifically scheme can be: be provided with a fuel-displaced duct in described inner carrier, the filler opening in this fuel-displaced duct is communicated with described brake grease chamber, the outlet in this fuel-displaced duct is connected with the attachment hole that described inner carrier external part is provided with, and this attachment hole has been threaded connection screw.
Further: described housing inner chamber is connected with described oil chamber by the oilhole that described inner carrier wall is provided with.
Further: described oil-controlling device comprises the container of a tubular, one end of this container is arranged on described housing outer wall, is provided with oil duct in this end, and the other end of described container is opening, lid with oilhole is installed on this opening, is provided with oil sealing in described lid and between described opening.
Further: described oil sealing is the plantation rubber cone of hollow.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, this braking device adopts inner carrier of many increases in piston, and unique oil duct design, make brake oil act on piston and inner carrier between, utilize inner carrier and brake oil pushing piston to stretch out and drive the brake of brake block locking hub for vehicle wheel, because brake oil can only flow at piston and inner carrier in the end face of piston and inner carrier oil duct, can't enter between the piston and inner walls and piston and inner carrier inwall of mutual motion, thereby the pollution of brake oil can't affect the motion of piston and housing, in addition, be connected with lubricant oil between piston and inner walls, under braking state, be piston with inner carrier when the end face of piston separates, this lubricant oil is back to the seal space in oil-controlling device, the pollution of avoiding that has kept lubricant oil, like this, the relative movement of whole piston and housing and piston and inner carrier is not subject to the impact of the adhesion of brake oil, do not affect separating of brake and brake block and hub for vehicle wheel, namely almost avoided the appearance of " waiting to stop " state, brake sensitivity is high, traveling state of vehicle is greatly improved, the load that travels decreases, greatly increase the working life of braking device,
2, this structure of this braking device, can make whole braking device under long-term obsolete state, even if be subject to the impacts such as temperature, humidity and brake oil be unclean, piston and inner carrier are by corrosion, do not affect relative movement between piston and inner walls and piston and inner carrier inwall, namely do not affect the sensitivity of brake, thereby this braking device has higher reliability.
