Description
Technical field
The present invention relates to the technical field of structure for controlling mounting force of locating pin of automobile hydraulic power steering gear, relate to concretely a kind of automobile hydraulic power-driven steering gear locating dowel pin pressure control structure.
Background technology
In the power steering assembling course of processing, steering screw hole needs finger setting with coordinating of torsion bar, and traditional method is to adopt oil press to guarantee this delivery pressure.In this process, the force value of by pass valve will be set in a fixed value, when the force value of whole system work during higher than this fixed value by pass valve just can play the effect of pressure release.Yet, for be pressed into locating dowel pin in certain pressure range, between locating dowel pin and hole, coordinate the situation that all belongs to qualified, currently used hydraulic efficiency pressure system can not actv. judge between locating dowel pin and hole, coordinate whether qualified.If inferior-quality cooperation, by the serious hidden danger of quality producing in serious vehicle traveling process.
Summary of the invention
Defect in view of prior art existence, the object of this invention is to provide a kind of hydraulic power steering device locating dowel pin setting pressure control structure, to process for be pressed into locating dowel pin within the scope of authorized pressure, can guarantee the situation that all belongs to qualified that coordinates between locating dowel pin and hole.Guarantee the reliability of the safety traffic of automobile.
The technical solution adopted for the present invention to solve the technical problems is: structure for controlling mounting force of locating pin of automobile hydraulic power steering gear, comprises compression indicator, oil cylinder, three position four-way electromagnetic valve, left check valve, right check valve, left by pass valve, right by pass valve, two-bit triplet electromagnetic valve, unidirectional quantitative hydraulic pump and oil filter; Described oil cylinder connects three position four-way electromagnetic valve, three position four-way electromagnetic valve one side Bonding pressure table, opposite side be connected in parallel left check valve and right check valve; Left check valve one side connects left by pass valve, and opposite side connects two-bit triplet electromagnetic valve, and right check valve one side connects right by pass valve, and opposite side connects two-bit triplet electromagnetic valve; Two-bit triplet electromagnetic valve connects unidirectional quantitative hydraulic pump, connects unidirectional quantitative hydraulic pump and connects oil filter.
Principle of work of the present invention is: structure for controlling mounting force of locating pin of automobile hydraulic power steering gear, comprises compression indicator, oil cylinder, three position four-way electromagnetic valve, left check valve, right check valve, left by pass valve, right by pass valve, two-bit triplet electromagnetic valve, unidirectional quantitative hydraulic pump and oil filter; Described oil cylinder connects three position four-way electromagnetic valve, three position four-way electromagnetic valve one side Bonding pressure table, opposite side be connected in parallel left check valve and right check valve; Left check valve one side connects left by pass valve, and opposite side connects two-bit triplet electromagnetic valve, and right check valve one side connects right by pass valve, and opposite side connects two-bit triplet electromagnetic valve; Two-bit triplet electromagnetic valve connects unidirectional quantitative hydraulic pump, connects unidirectional quantitative hydraulic pump and connects oil filter.After being pressed into, there is compression indicator to show pressure condition.By the link of these part special constructions, can in whole system, guarantee the situation that all belongs to qualified that coordinates between locating dowel pin and hole.
The present invention is simple in structure, easy to operate, can process for be pressed into locating dowel pin in certain pressure range, between locating dowel pin and hole, coordinates the situation that all belongs to qualified.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The Reference numeral of Fig. 1 is as follows: compression indicator 1, oil cylinder 2, three position four-way electromagnetic valve 3, left check valve 4a, right check valve 4b, left by pass valve 5a, right by pass valve 5b, two-bit triplet electromagnetic valve 6, unidirectional quantitative hydraulic pump 7, oil filter 8.
The specific embodiment
Specific embodiment:
Structure for controlling mounting force of locating pin of automobile hydraulic power steering gear as shown in Figure 1, comprises compression indicator 1, oil cylinder 2, three position four-way electromagnetic valve 3, left check valve 4a, right check valve 4b, left by pass valve 5a, right by pass valve 5b, two-bit triplet electromagnetic valve 6, unidirectional quantitative hydraulic pump 7 and oil filter 8; Described oil cylinder 2 connects three position four-way electromagnetic valves 3, three position four-way electromagnetic valve 3 one side Bonding pressure tables 1, opposite side be connected in parallel left check valve 4a and right check valve 4b; Left check valve 4a mono-side connects left by pass valve 5a, and opposite side connects two-bit triplet electromagnetic valve 6, and right check valve 4b mono-side connects right by pass valve 5b, and opposite side connects two-bit triplet electromagnetic valve 6; Two-bit triplet electromagnetic valve 6 connects unidirectional quantitative hydraulic pump 7, connects unidirectional quantitative hydraulic pump 7 and connects oil filter 8.
In the power steering assembling course of processing, need to there be a finger setting in steering screw hole with coordinating of torsion bar, by pin positioning device for use, check to be pressed into pressure, the power of supposing to be pressed into locating dowel pin at 3000N to coordinating between locating dowel pin and hole all belongs to qualified in the scope of 15000N.
In use, by the pressure setting of left check valve 4a, be 3000N, by the pressure setting of right check valve 4b, be 15000N, when the power with 3000N can be pressed into smoothly, illustrate that the tolerance clearance between locating dowel pin and hole is excessive, at this moment need to change next group, if this group can not be pressed under the power of 3000N, two-bit triplet electromagnetic valve 6 must be electric, and device is changed to high pressure, if locating dowel pin can be pressed into smoothly, illustrate that pin and coordinating of hole are rational.If device changes into after high pressure, locating dowel pin still cannot be pressed into, and illustrates that pin coordinates with hole improper.So can actv. detect coordinating of locating dowel pin and hole.
