Description
Technical field
The utility model relates to brake device for car, is specifically related to a kind of hydraulic type multi-cylinder hub branch pump device of stopping.
Background technique
The single cylinder generally using on automobile at present or the twin-tub hub point pump assembly of stopping adopts an oil cylinder piston driving horse shoe shaped friction plate, its brake area can only be confined to the sub-fraction of brake hub annular, the braking force producing is less, moreover the outer arc radius of curvature of horse shoe shaped friction plate is not identical with the radius of wheel hub inner friction surface, even if can not accomplish when same action that both are concentric, so that rubbing surface discontinuity in wheel hub, braking stationarity, poor reliability, wearing and tearing are large, and working life is short.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, brakes that stressed evenly having stable behavior is reliable, the hydraulic type multi-cylinder hub of the long service life branch pump device of stopping.
For solving the problems of the technologies described above, the utility model hydraulic type multi-cylinder hub branch pump device of stopping, be included in the friction plate with circumference uniform distribution in wheel hub, described friction plate corresponding after be equipped with friction plate end liner, described wheel hub is provided with square cylinder between two parties, and described square cylinder is provided with some holding down bolts and orientation angle; Described friction plate end liner is slightly flexibly connected with square cylinder by corresponding cylinder body location respectively; Described square cylinder side is provided with some pistons, and described piston nose contacts with friction plate end liner, and described piston tail end is communicated with total asphalt channel by point asphalt channel, and described total asphalt channel is communicated with filler opening.The utility model synchronously drives corresponding piston to be with movable friction plate friction wheel hub inwall to complete braking maneuver by the hydraulic oil of total asphalt channel by a point asphalt channel again.The outer arc radius of curvature of friction plate is identical with the radius of rubbing surface in hub for vehicle wheel, and when braking, in friction plate and hub for vehicle wheel, the area of contact of rubbing surface is large, thereby increases the stationarity of brake and increase braking moment.The external general braking pump of filler opening, each point of asphalt channel interconnects with total asphalt channel, to ensure that each piston action is synchronous and rubbing surface in hub for vehicle wheel is produced to uniform active force.The arc shaped surface of friction plate end liner is directly connected with friction plate, and friction plate end liner is located slightly and guaranteed transmission stability in the displacement of square cylinder upper limit by cylinder body, and when braking, orientation angle stops the displacement of friction plate end liner side; Square cylinder is connected with vehicle suspension by holding down bolt, and hub for vehicle wheel is connected with rotatingshaft, forms the drive part of wheel.
Further, described friction plate is set to four.When braking, friction plate contacts fully with wheel hub inwall, improves retardation efficiency, reaches optimum braking effect, can significantly extend the working life of friction plate and wheel hub simultaneously.
Further, each side of described square cylinder is all provided with one group of piston.When braking, friction plate end liner is stressed evenly, brakes sensitive, efficient.
The utility model is simple in structure, and retardation efficiency is high, long service life, the Security that has effectively improved Vehicle Driving Cycle.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic perspective view of the utility model square cylinder.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1 and Figure 2, the utility model hydraulic type multi-cylinder hub branch pump device of stopping, be included in the friction plate 4 with circumference uniform distribution in wheel hub 3, after described friction plate 4 correspondences, be equipped with friction plate end liner 5, described wheel hub 3 is provided with square cylinder 1 between two parties, and described square cylinder 1 is provided with some holding down bolts 6 and orientation angle 8; Described friction plate end liner 5 slightly 7 is flexibly connected with square cylinder 1 by corresponding cylinder body location respectively; Described square cylinder 1 side is provided with some pistons 2, and described piston 2 front ends contact with friction plate end liner 5, and described piston 2 tail ends are communicated with total asphalt channel 11 by point asphalt channel 9, and described total asphalt channel 11 is communicated with filler opening 10.
Described friction plate 4 is set to four.
Each side of described square cylinder 1 is all provided with one group of piston 2.
When action, the high pressure liquid force feed that general braking pump produces imports total asphalt channel 11 through filler opening 10, promote the front displacement of corresponding piston 2 by a point asphalt channel 9 again, according to the principle of liquid transfer pressure, the high pressure pressure of liquid acts on each piston 2 simultaneously, and the pressure obtaining on each piston 2 is the pressure that the area of piston 2 is multiplied by liquid; Owing to being many pistons 2, the power acting on friction plate end liner 5 is exactly many times of single piston 2, so obtain larger frictional force.Friction plate 4 outer arc radius of curvature of the present utility model are identical with the radius of wheel hub 3 interior rubbing surfaces, when brake, friction plate 4 reaches maximum with the area of contact of wheel hub 3 inner friction surfaces, thereby increase the stationarity of brake and increase braking moment, also having reduced the wearing and tearing of friction plate 4 and wheel hub 3 simultaneously.Each point of asphalt channel 9 is communicated with total asphalt channel 11, and the pressure that therefore each piston 2 obtains is identical, has ensured that each piston 2 moves simultaneously and wheel hub 3 inner friction surfaces are produced to uniform active force.The arc shaped surface of friction plate end liner 5 is directly connected with friction plate 4, friction plate end liner 5 another sides locate slightly 7 in square cylinder 1 upper limit displacement by cylinder body, when brake cylinder body location slightly 7 and the orientation angle 8 of square cylinder 1 stoped the side displacement of friction plate end liner 5 to guarantee the stability of braking, the rotatory force of wheel is passed to square cylinder 1 by wheel hub 3 through friction plate 4, friction plate end liner 5, then conducts to automotive body by square cylinder 1 and complete braking.
The utility model is simple in structure, easy to operate stable, reliable, has extended the working life of automobile brake parts, the Security that has improved automobile running.
