Abstract
本发明涉及一种汽车制动装置，即一种改进的汽车刹车泵。它包括油缸，在油缸内移动的活塞柱，油缸中部有进油孔，前部有出油孔，活塞柱前部顶接有回位弹簧。油缸内间隔环设有两块与活塞柱滑接的凸台，使活塞柱运行稳定。每个凸台两侧的油缸通过凸台内的孔道连通，活塞柱与油缸之间运滑效果好。活塞柱中部有与油缸进油腔连通的过油孔。油缸在两块凸台之间断开密封连接，即通过压盖和套在活塞柱上的密封圈与前部油缸端部拧压接，密封圈的边沿也被压在油缸端面上，密封圈处于静态工作状态，密封效果好。后部油缸与压盖后部连接。活塞柱与油缸之间双位环面支撑，运行稳定，润滑好，密封可靠，寿命长，耐高压，使用安全。
The invention relates to an automobile brake device, namely an improved automobile brake pump. It includes an oil cylinder, a piston rod moving in the oil cylinder, an oil inlet hole in the middle part of the oil cylinder, an oil outlet hole in the front part, and a return spring connected to the top of the front part of the piston rod. The inner spacer ring of the oil cylinder is provided with two bosses that slide with the piston rod, so that the piston rod runs stably. The oil cylinders on both sides of each boss are connected through the holes in the boss, and the sliding effect between the piston rod and the oil cylinder is good. There is an oil hole in the middle of the piston rod which communicates with the oil inlet chamber of the oil cylinder. The oil cylinder disconnects the sealing connection between the two bosses, that is, through the gland and the sealing ring set on the piston rod, it is screwed and crimped with the end of the front oil cylinder, and the edge of the sealing ring is also pressed on the end face of the oil cylinder, and the sealing ring is in the Static working state, good sealing effect. The rear oil cylinder is connected with the rear of the gland. The two-position annular surface support between the piston rod and the oil cylinder has stable operation, good lubrication, reliable sealing, long service life, high pressure resistance and safe use.
Description
Technical field
The present invention relates to a kind of brake device for car, promptly improved car brake pump.
Background technology
In prior art, car brake pump comprises brake cylinder, the piston boit that in oil cylinder, moves, and there is fuel feed hole at the oil cylinder middle part, and front end has oil outlet.The piston boit front end has had the rubber oil sea of the withstand voltage effect of sealing; There is conventional seals (not withstand voltage) at the piston boit rear portion, play that the oilhole of sealing oil cylinder flows out naturally outside hydrodynamic do not flow to from behind, wherein two oil sealings one (front end) are withstand voltage oil sealings, another (rear end) is pressure-proof not.When piston boit moves, axial restraint is two oil sealings before and after relying on, because of oil sealing is the rubber manufacturing, so hardness is not enough, can not compare with metal, secondly, axial contact area is little, rub proofness is also relatively low, uses a period of time can make the very big gap of generation between oil cylinder and the piston boit, makes the rear closure of oil cylinder and piston boit not tight, produce oil leakage phenomenon, master brake cylinder can not continue to use (brake failure), and the withstand voltage oil sealing section of front end is less, and its design access times only are 500,000 troubles free of work under the 100mpa.
Summary of the invention
The object of the invention is to provide a kind of stable performance, safe and reliable car brake pump at above-mentioned deficiency.
Technical solution of the present invention is: a kind of car brake pump comprises oil cylinder, the piston boit that in oil cylinder, moves, and there is fuel feed hole at the oil cylinder middle part, and there is oil outlet the front portion, and the anterior apical grafting of piston boit has pull back spring.Spacer ring is provided with two boss that slip with piston boit in the oil cylinder, makes piston boit stable.The oil cylinder of each boss both sides is by the hole link in the boss, and fortune is sliding effective between piston boit and the oil cylinder.There is the oil-through hole that is communicated with the oil cylinder oil suction chamber at the piston boit middle part.Oil cylinder disconnects between two boss and being tightly connected, and promptly twists crimping by gland and the seal ring and the anterior oil cylinder end that are enclosed within on the piston boit, and the edge of seal ring also is crushed on the oil cylinder end face, good sealing effect.The rear portion oil cylinder is connected with the gland rear portion.
Advantage of the present invention is: 1, adopt the dibit anchor ring to support between piston boit and the oil cylinder, and stable, lubricate, seal ring is in the quiescent operation state, and the sealing position is long, and sealing is reliable.2, its design access times are 100mpa 1,000,000 troubles free of work down, and the life-span is long, and is high pressure resistant, uses safer.
Below in conjunction with accompanying drawing the present invention is described in further detail.
Description of drawings
Accompanying drawing is a structure diagram of the present invention.
The specific embodiment
Referring to accompanying drawing, car brake pump comprises oil cylinder 1, the piston boit 2 that in oil cylinder 1, moves, and there is fuel feed hole 3 at oil cylinder 1 middle part, and there is oil outlet 4 front portion, and piston boit 2 anterior apical graftings have pull back spring 5.Spacer ring is provided with two boss 6,7 that slip with piston boit 2 in the oil cylinder 1, and the oil cylinder of each boss 6,7 both sides is communicated with by the duct in the boss 8, and duct 8 can be provided with one to four along periphery.There is the oil-through hole 9 that is communicated with oil cylinder 1 oil suction chamber at piston boit 2 middle parts.Oil cylinder 1 disconnects between two boss 6,7 and being tightly connected, and promptly twists crimping by gland 10 and the seal ring 11 that is enclosed within on the piston boit 2 with anterior oil cylinder end, and rear portion oil cylinder and gland 10 rear portions are twisted and connect in succession, locatees by adjusting nut 12.Seal ring 11 is twisted under the pressure effect at oil pressure and gland, seals very reliable.
When driver's pin touches on the brake pedal, promote piston boit 2 to reach (or title) by connecting rod mechanism to moving to left, promote fluid and act on brake shoe brake cheek realization braking, pin leaves pedal, and then piston boit 2 is retracted position (or claiming to move right) after under pull back spring 5 effects.
