Abstract
The utility model discloses an adjustable load sensing hydraulic braking proportional valve used in vehicle. Based on the prior proportional valve, a sliding valve pocket 16, an adjusting bolt 15 and a latch nut 14 are additionally arranged on the left end of the valve body 1, wherein the left end of the sliding valve pocket 16 is connected with the right end of the adjusting bolt 15. The utility model mainly aims to solve the problem of the allocation proportion of the front braking force and the rear braking force under different load conditions. In addition to change the allocation proportion of the front braking force and the rear braking force automatically with the changing load to approximate ideal allocation curve under different load conditions, but also can overcome the processing error in the process of manufacture due to adopting the newly developed adjustable structure, therefore, the operating characteristic can be adjusted and determined accurately and handily when assembling and using to match the entire braking system of the vehicle more, thereby improve the braking performance of vehicles to secure traffic safety.
Description
Technical field: the utility model relates to the moving apportioning valve of sense carrier fluid compacting in the hydraulic braking system for automobile, and particularly a kind of automobile moves apportioning valve with adjustable sense carrier fluid compacting.
Background technology: the at present domestic production of having finalized the design, be not equipped with as yet in the hydraulic brake system of lilliput car of ABS anti-lock device, the load sensing valve that has many vehicles to adopt to introduce by Japanese Toyota Company as before, back device to apply correction to braking force, it can automatically change according to the magnitude of load of automobile automobile before, the allocation proportion of back braking force, make it near automobile under the different loads situation before, the ideal Distribution curve of back braking force, year sense apportioning valve of this introduction is simple in structure, but operating characteristic is subjected to the influence of manufacturing errors easily, and adjust difficult, the user reflects that generally the automobile brake perfrmance that this load sensing valve is housed is undesirable, often this valve is removed.Have many producers have to when new car dispatches from the factory the load sensing valve of this introduction to be removed for the requirement of satisfying the user, perhaps the apportioning valve with other replaces.Say technically, this is a kind of falling back, because behind the dismounting load sensing valve, before the automobile, the allocation proportion of back braking force will become fixed ratio, at the automobile emergency glancing impact, the dangerous situation of trailing wheel prior to the front-wheel locking can appear, jeopardize traffic safety, and replace with apportioning valve, under the proper prerequisite of apolegamy, when automobile is unloaded before, the allocation proportion of back braking force might be near ideal curve, but when the load of automobile increases, this allocation proportion will depart from ideal curve, and the load that automobile increases is big more, and this situation that departs from ideal curve is just serious more.
Summary of the invention: the purpose of this utility model is to provide a kind of automobile to move apportioning valve with adjustable sense carrier fluid compacting, utilize this apportioning valve just can overcome the influence of relevant manufacturing errors or usage condition, guarantee that the operating characteristic energy of load sensing valve and the braking performance of vehicle of automobile mate preferably, thereby the raising braking performance of automobile, guarantee driving safety.
Formation of the present utility model: it comprises valve body, spool, balance spring, plug screw, the jump ring circle, the location retainer, sealing member, spring perch, the spool leather cup, packing element, jam nut, adjustable bolt, the slip valve pocket, packing ring, air extractor vent and advancing, fluid hole, the inside of valve body 1 and left end have slip valve pocket 16, packing element 13, adjustable bolt 15 and jam nut 14, packing element 13 is installed in the outside of slip valve pocket 16, slip valve pocket 16 is installed in the epitrochoidal chamber of valve body 1, adjustable bolt 15 and jam nut 14 are installed in valve body 1 left end, and the right-hand member of the left end of slip valve pocket 16 and adjustable bolt 15 is in contact with one another.
Compared with the prior art, the utility model is for keeping interchangeability, be convenient to install and use, keeping under former valve body profile and the basic unmodified situation of structure, redesigning and increased for the adjustment of the operating characteristic of load sensing valve and determine vital slip valve pocket, packing element, adjustable bolt and jam nut.These elements that increases newly have been arranged, just can when assembling or when using maintenance, change the relative position that slide-valve is enclosed within valve inner by rotating adjustable bolt quickly and easily, thereby change the predetermincd tension of balance spring.Utilize this method just can overcome the influence of relevant manufacturing errors or usage condition, guarantee that the operating characteristic energy of load sensing valve and the braking performance of vehicle of automobile mate preferably, thereby improve braking performance of automobile, guarantee driving safety.The utility model reliable operation, easy to adjust, can improve the deceleration and stopping performance of automobile under the different loads condition.
