Background technique
The single cylinder disc brake wheel cylinder assembly that brake is generally used on the automobile at present, owing to adopt single oil cylinder, brake area can only be confined to the sub-fraction of brake block annular, the braking force that produces is less, discontinuity, and the braking stationarity is poor, the braking reliability is not high, and it is larger to wear and tear, and working life is short.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile multi-cylinder disc brake branch pump device, and this device adopts Multi-cylinder to drive annular friction plate structure, and braking force is large, and stressed evenly reliable in action is braked steadily, and it is little to wear and tear, long service life.
In order to achieve the above object, a kind of automobile multi-cylinder disc brake of the utility model branch pump device, comprise cylinder body, be located at the oil cylinder on the cylinder body, be located at in-oil cylinder piston, be fixed on the brake disc on the wheel axle, fixedly be located at the left and right sides friction plate of brake disc both sides, fixedly turn in one's mind at the bottom of the left and right sides friction plate of left and right sides friction plate respectively, it is characterized in that: described oil cylinder has a plurality of, be evenly distributed on the cylinder body, communicate with one another by asphalt channel between a plurality of oil cylinders, left and right sides friction plate is structure ringwise all, turn in one's mind at the bottom of the left friction plate and fix with the friction plate fixing frame, turning in one's mind at the bottom of the right friction plate slightly to be fixed on the cylinder body by friction plate location carries out spacing to it, the oil cylinder oil inlet mouth links to each other with general braking pump by oil pipe, cylinder body and friction plate fixing frame are fixedly linked, and cylinder body slightly is connected with annular fixed support by the cylinder body location.
In technique scheme, the utility model adopts the Multi-cylinder annular evenly to distribute, communicate with one another by asphalt channel between each oil cylinder, each in-oil cylinder piston action is consistent, piston actuated annular friction sheet, cylinder body slightly forms the slip localization part by the cylinder body location in annular fixed support, to form unsteady clamp type structure, left friction plate directly is fixed on the friction plate fixing frame turning in one's mind at the bottom of the left friction plate by bolt, saved caliper arrangement, right friction plate is turned in one's mind at the bottom of with right friction plate slightly spacing on cylinder body by the friction plate location, forms floated driving.The utility model adopts Multi-cylinder to drive annular friction plate structure and has the following advantages: the first, and braking force is large; The second, stressed even, reliable in action, braking is steadily; The 3rd, it is little to wear and tear, the friction plate long service life.
Description of drawings
Fig. 1 is the structure sectional view of a kind of automobile multi-cylinder disc brake of the utility model branch pump device;
Fig. 2 is the structural representation of cylinder body of the present utility model.
Embodiment
Below in conjunction with accompanying drawing a kind of automobile multi-cylinder disc brake of the utility model branch pump device is described in further detail.
As shown in Figure 1 and Figure 2, present embodiment by cylinder body 1, be located at oil cylinder 2 on the cylinder body 1, be located at piston 3 in the oil cylinder 2, be fixed on brake disc 5 on the wheel axle 4, be bolted to connection at the left and right sides friction plate 6 and 7 of brake disc 5 both sides, fixedly turning in one's mind at the bottom of left and right sides friction plate 6 and 7 the left and right sides friction plate respectively 8 and 9 forms.In the present embodiment, oil cylinder 2 has 8, annular is evenly distributed on the cylinder body 1, pistons 3 in each oil cylinder 2 drive left and right sides friction plates 6 and 7, communicate with one another by asphalt channel between the oil cylinder 2, and left friction plate 6 and right friction plate 7 be structure ringwise all, it is 8 fixing with friction plate fixing frame 10 to turn in one's mind at the bottom of the left friction plate, saved the caliper arrangement on the present automobile, turning in one's mind at the bottom of the right friction plate 9 slightly 11 is fixed on the cylinder body 1 and it is carried out spacing by friction plate location, forms floated driving.Oil cylinder oil inlet mouth 12 links to each other with general braking pump by oil pipe, cylinder body 1 is bolted with friction plate fixing frame 10 and links to each other, cylinder body 1 slightly 13 is connected with annular fixed support 14 by cylinder body location, cylinder body 1 slightly 13 forms the slip localization part by the cylinder body location in annular fixed support 14, to form unsteady clamp type structure.
The working principle of present embodiment: the filler opening 12 that enters present embodiment multi-cylinder disc brake branch pump device from the highly pressurised liquid of general braking pump generation through transport pipe, enter each oil cylinder 2 by asphalt channel again, principle according to liquid transfer pressure, the high pressure pressure of liquid acts on the piston 3 in each oil cylinder 2 simultaneously, the pressure that obtains at each piston 3 is that the area of piston multiply by the pressure of liquid.Because 8 oil cylinders 2 of present embodiment are worked simultaneously, acting on the power of turning in one's mind at the bottom of the friction plate of the left and right sides on 8 and 9 by piston 3 is exactly 8 times of single oil cylinder, so the braking force that obtains on left and right sides friction plate 6 and 7 is larger, right side friction plate 7 is pressed towards brake disc 5 at this moment, and brake disc 5 is to be fixed on the wheel axle 4 of wheel, axially can not move, cylinder body 1 slides backward under the driving of reaction force, and move to same direction with the friction plate of movable friction plate fixing frame 10 and opposite side, realized the relative movement of both sides friction plates, brake disc is clamped, the rotation of wheel is stopped, realizing the braking process of vehicle.Present embodiment adopts Multi-cylinder to drive annular friction plate structure and has the following advantages: the first, and braking force is large; The second, stressed even, reliable in action, braking is steadily; The 3rd, it is little to wear and tear, the friction plate long service life.
