Abstract
The utility model relates to a shock absorber for a steering engine. The shock absorber comprises a liquid storage cylinder and a compression valve assembly. A piston rod is arranged inside the liquid storage cylinder. A rebuilt valve assembly is arranged at the bottom end of the piston rod. An oil seal guider assembly is arranged between the piston rod and the liquid storage cylinder. A flow restriction orifice is formed in the side wall of the liquid storage cylinder. An air bag is arranged on the outer wall of the liquid storage cylinder. The air bag is communicated with an inner cavity of the liquid storage cylinder through the flow restriction orifice. The shock absorber is simple in structure, convenient to produce and process, high in assembling efficiency and stable in product performance, and the installation quality can be ensured. In the using process of the shock absorber, idle running, noise and abnormal noise can be avoided, the compression valve assembly is positioned through a liquid storage cylinder rolling groove, installation is convenient, production hours are saved, and the performance is stable.
Description
Technical field
The utility model relates to a kind of steering box vibration damper.
Background technique
Steering box, because of its feature at assembly space and need of work, is generally single cylinder design, and its compression valve is as assembly location-independent when assembling, be installed on the middle part of clutch release slave cylinder, technological requirement is complicated, and difficulty of processing is large, efficiency of assembling is low, also cannot be guaranteed qualitatively.
In addition, in prior art, during steering box work, it is horizontal position, so just need to be full of in clutch release slave cylinder working medium, because piston rod is in to-and-fro motion process, when entering clutch release slave cylinder, piston rod need to take certain volume, because fluid can not be compressed, so need to design an additional air bag.Existing device product poor stability, production and processing difficulty is large, has noise and abnormal sound in using process, affects the using effect of product.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of steering box vibration damper simple in structure.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of steering box vibration damper, it comprises surge drum, is arranged on the compression valve assembly in surge drum, described compression valve assembly is divided into upper and lower two chambers by the inner chamber of surge drum, in described surge drum, be provided with the piston rod of an axial motion, described piston rod bottom is provided with rebuilt valve assembly, is provided with oil sealing guider assembly between described piston rod and surge drum;
On described surge drum sidewall, throttle orifice is set, described throttle orifice is positioned at compression valve assembly bottom, and described surge drum outer wall is provided with air bag, and described air bag is communicated with the inner chamber of surge drum by throttle orifice.
Further, described air bag arranged outside has outer stack shell.
Further, described outer stack shell adopts closing in orientation type that air bag and outer stack shell are fixed on surge drum.
Further, described compression valve assembly and surge drum inwall adopt the mode of slot rolling location to fix.
Further, described piston rod top is provided with bulb assembly.
Further, between described bulb assembly and surge drum, be provided with boot seal.
Further, described bulb assembly and piston rod are threaded connection, and on the internal thread that described bulb assembly is connected with piston rod, are provided with and detest glue.
The beneficial effect that adopts technique scheme to produce is:
The utility model is simple in structure, and production and processing is convenient, and efficiency of assembling is high, and product performance are stable, and installation quality can be guaranteed.In using process, can avoid idle running, noise and abnormal sound.Compression valve assembly is adopted to surge drum slot rolling location, easy for installation, save production hour, and stable performance.Perforate on the surge drum of compression valve bottom, and air bag is set at surge drum outward, outer stack shell reducing fixation balloon, thus meet the usage requirement of little cylinder diameter steering box.
