Abstract
The utility model relates to an automobile steering power cylinder assembly with joints. A left joint assembly and a right joint assembly are spherical hinge assemblies; a cylinder barrel assembly is formed by welding a connecting cover and a cylinder barrel; the cylinder barrel is provided with a left oil inlet and outlet joint and a right oil inlet and outlet joint; a piston assembly is fixed on a piston rod through a self-locking nut; the left oil inlet and outlet joint and the right oil inlet and outlet joint are positioned on the two sides of the piston assembly respectively; installing grooves of a dustproof cover are formed at the right end of the piston rod and the right end of the cylinder barrel; and the dustproof cover is fixed on the installing grooves of the cylinder barrel and the piston rod through hose hoop belts. When a driver turns a steering wheel, oil discharged by an oil pump enters one of a left cavity and a right cavity through a control valve under the push of the control valve, pressure is generated under the action of ground steering resistance, the piston assembly is pushed, a high-pressure cavity and a low-pressure cavity are formed, and a power-assisted steering effect is achieved through a pressure difference; and the dustproof cover can be prevented from being directly exposed to air, and the aging rate of the dustproof cover is reduced.
Description
Technical field
The utility model relates to the motor turning work-saving device, is specifically related to a kind of motor turning power cylinder belt lacing assembly.
Background technology
On automobile, use power cylinder, can reduce the motor turning hand-power greatly, alleviate the labour intensity of chaufeur, improve the sensitieness of vehicle mobility and driving.According to the difference of flow mode in the system, can be divided into gerotor type hydraulic booster and permanent current formula hydraulic booster.The characteristics of gerotor type hydraulic booster system are that no matter bearing circle is in center position or steering position, bearing circle keeps static or are rotating that the fluid in the system pipeline always keeps high pressure conditions; Though and the power steerig pump of permanent current formula hydraulic power-assisted steering system is worked all the time, when hydraulic booster system was not worked, oil pump was in idling conditions, and the load of pipeline is littler than gerotor type, and present most of hydraulic power-assisted steering system all adopts the permanent current formula.Can see that no matter which kind of mode, power steerig pump all is indispensable parts, it can be converted into the engine output power of input the pressure of fluid.Whole power cylinder assembly has high leakproofness, and its in-to-in oil liquid pressure is high, need possess dynamic seal and cooperate.Common piston rod and the part between the cylinder barrel are exposed in the air, adhere to impurity easily, influence in-use performance.
The utility model content
The purpose of the utility model is to provide a kind of motor turning power cylinder belt lacing assembly, and the mode of adopt permanent current formula hydraulic power-assisted steering, dust boot being installed between piston rod and cylinder barrel is that autotruck provides power steering.
For achieving the above object; The technical scheme of the utility model is: motor turning power cylinder belt lacing assembly; Comprise power cylinder assembly, left and right joint assembly; Said left connector assembly is fixed on the connection cover screw thread place of power cylinder assembly through screw thread, and said right connector assembly is fixed on the piston rod thread place through screw thread, and said left and right joint assembly is the globular hinge assembly; Said power cylinder assembly comprises cylinder barrel assembly, piston assembly, cylinder cap assembly and piston rod, and said cylinder barrel assembly is welded to form by connection cover and cylinder barrel, and cylinder barrel is provided with oily joint of left side turnover and the oily joint of right turnover; Fixed a piston assembly through self lock nut on the said piston rod, turnover oily joint in a left side passes in and out the both sides that oily joint lays respectively at piston assembly with the right side; Said cylinder cap assembly is fixed on the cylinder barrel with elastic spring and an axle-steel silk back-up ring through a hole; The right-hand member of said piston rod and the right-hand member of cylinder barrel are respectively equipped with the dust boot mounting groove, and dust boot is fixed on the mounting groove of cylinder barrel and piston rod through the hose loop band.
When adopting technique scheme, two chambers about cylinder barrel is divided into by piston assembly, left chamber passes in and out oily joint through a left side and communicates with the oil pump oil return line, and right chamber passes in and out oily joint through the right side and communicates with the oil pump oil return line, and whole power cylinder has high leakproofness.When the chaufeur steering wheel rotation, promote down in control cock, the fluid that oil pump is discharged is a chamber wherein, two chambeies through about the control cock entering; Under the cornering resistance effect of ground, produce pressure; Promote piston assembly, form high-low pressure two chambeies, difference of pressure works the power-assisted effect that turns to.Reduce the motor turning hand-power greatly, alleviate the labour intensity of chaufeur, improve the sensitieness of vehicle mobility and driving.In addition, the part between piston rod and cylinder barrel is coated in the dust boot, avoids directly being exposed in the air, slows down its aging speed.
Further, the oily joint of said left turnover all is equipped with the screw thread obstruction with the oily joint of right turnover.
Further, the ball pin pendulum radius of said globular hinge assembly is 35 °.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model motor turning power cylinder belt lacing assembly embodiment;
Fig. 2 is the structural representation of the utility model motor turning power cylinder assembly embodiment.
The specific embodiment
As illustrated in fig. 1 and 2, the utility model motor turning power cylinder belt lacing assembly has comprised power cylinder assembly 1, and right ends bonded assembly connector assembly.Wherein left connector assembly 21 is fixed on the connection cover 31 screw thread places of power cylinder assembly 1 through screw thread; Right connector assembly 22 is fixed on piston rod 6 screw thread places through screw thread, and above-mentioned left and right joint assembly is the globular hinge assembly, and the ball pin pendulum radius of this globular hinge assembly is a=35 °.Power cylinder assembly 1 has comprised cylinder barrel assembly 3, piston assembly 4, cylinder cap assembly 5 and piston rod 6 several sections.Cylinder barrel assembly 3 is welded to form by connection cover 31 and cylinder barrel 32, and cylinder barrel 32 is provided with oily joint 321 of left side turnover and the oily joint 322 of right turnover; Fixed a piston assembly 4 through self lock nut 61 on the piston rod 6, turnover oily joint 321 in a left side passes in and out the both sides that oily joint 322 lays respectively at piston assembly 4 with the right side, forms two independently oil closed cavities.Cylinder cap assembly 5 is fixed on the cylinder barrel 32 with elastic spring 51 and an axle-steel silk back-up ring 52 through a hole.Turnover oily joint 321 in a said left side all is equipped with screw thread with the oily joint 322 of right turnover and stops up.The right-hand member of the right-hand member of piston rod 6 and cylinder barrel 32 is respectively equipped with the mounting groove of dust boot 7, and dust boot 7 is fixed on the mounting groove of cylinder barrel 32 and piston rod 6 through hose loop band 71.
