Chinese patent Authorization Notice No. is CN203202072U, authorized announcement date is that the utility model patent on September 18th, 2013 discloses a kind of clutch booster push rod being provided with lengthening swivel nut, the clutch booster push rod length overcoming prior art or seldom can not can only adjust the defect that it is hindered when installing, debugging or changing, there is provided the push rod that a kind of length is fully adjustable, this function makes it very convenient when installing, debugging or changing.Comprise push rod and swivel nut, push rod front end is push rod cup, push rod is provided with shoulder close to the position of rear end, the rear end of shoulder is cylindrical section, swivel nut is for lengthening swivel nut, the back segment lengthening swivel nut is provided with screw, and the leading portion lengthening swivel nut is provided with lengthened cylindrical hole, and described cylindrical section is press-fitted with the position, front end in lengthened cylindrical hole and is connected.Although this model utility can motor-driven adjustment push rod length, still there is following defect in it:
1, the push rod front end of this model utility is that metallic material makes, directly contact between push rod end with clutch release fork ball-and-socket, cause between clutch push rod front end and clutch release fork ball-and-socket and mutually wear and tear, the disabler of the clutch booster caused.
Summary of the invention
The purpose of this utility model is the problem overcoming the wearing and tearing mutually between push rod front end and disengaging yoke ball-and-socket existed in prior art, provides a kind of and reduces the clutch booster push rod worn and torn between push rod front end and disengaging yoke ball-and-socket.
For realizing above object, technical solution of the present utility model is:
The clutch booster push rod reduced wear, comprise pusher body and the push rod cup of integrative-structure, described push rod cup is arranged at one end of pusher body, and the other end of pusher body is connected with the cylinder piston of clutch booster;
Described push rod cup outer cover is provided with pushrod bushing, and described pushrod bushing is the cylindrical structural of hollow, and the cross section of pushrod bushing takes the shape of the letter U, the inwall of pushrod bushing and the outer wall transition fit of push rod cup.
The cross section of described pushrod bushing is the uniform U-shaped structure of thickness, and the thickness d of pushrod bushing is 2 millimeters ~ 3 millimeters, and the height h of pushrod bushing is 18 millimeters ~ 22 millimeters.
Described pushrod bushing adopts polyamide, polyoxymethylene, polycarbonate (PC) or herd polyvinyl chloride material manufacture.
Compared with prior art, the beneficial effects of the utility model are:
1, the push rod cup in a kind of clutch booster push rod reduced wear of the utility model is arranged with pushrod bushing, to avoid between push rod cup with clutch release fork ball-and-socket direct contacts, effectively prevent push rod cup from shortening because of long term wear and cause the situation of clutch booster disabler, extend the working life of clutch power-assisted push rod, reduce maintenance cost.Therefore, the design can reduce the wearing and tearing between clutch release fork ball-and-socket and power-assisted push rod, extends the working life of power-assisted push rod and clutch release fork.
2, in a kind of clutch booster push rod reduced wear of the utility model, the pushrod bushing of the design adopts polyamide, polyoxymethylene, polycarbonate (PC) or herd polyvinyl chloride material manufacture, not only mechanical strength is high, wear resistance is strong for the pushrod bushing that above-mentioned material manufactures, and there is selflubricating effect, the friction between push rod and clutch release fork ball-and-socket can be reduced to the full extent, effectively extend the working life of clutch power-assisted push rod.Therefore, the pushrod bushing good mechanical property of the design, effectively reduces friction, and anti-throw-out lever shortens because of wearing and tearing.
