Abstract

The utility model discloses an assembling shock absorber with a replaceable inner core. Under the condition of unchanged connection mode of an original shock absorber and an existing entrucking and unchanged size of the original shock absorber and the existing entrucking, a welding connection mode of the top of a shock absorber outer housing and a gland bush is changed into a threaded connection mode, and the inner core of the shock absorber is covered by a coaxial cylindrical housing body. The bottom of the coaxial cylindrical shell body is sealed and the upper part of coaxial cylindrical housing body tightly presses an inner core oil seal to form a replaceable inner core assembly. A positioning sleeve is arranged in the position between the upper part of the replaceable inner core assembly and the shock absorber outer housing body. A rubber washer is arranged in the gland bush, and the matching point of the gland bush and an inner core piston is provided with a dust-proof rubber ring. Therefore, the utility model has the advantages of long service life, low manufacturing cost, cost saving and visibility.

Description

Core assembly formula vibration damper in replaceable

The utility model relates to a kind of replaceable interior core assembly formula vibration damper, belongs to auto parts machinery.

Along with economic development, taxi is increasing, and small and medium-sized cities are in the majority with Xiali, Alto especially, and behind the vibration damper frame, the frame upper end is integrally welded with gland because the vibration damper inner core is packed into for the vibration damper of these two kinds of vehicles, the vibration damper inner core is closed in it, and behind the easily damaged parts vibration damper inner core wear out failure, can't from the vibration damper frame, take out replacing, the vibration damper housing that have to even can continue to use is scrapped together and is thrown away, cause the wasting of resources, product cost height, user's maintenance cost height.

The utility model provides a kind of and only change inner core when vibration damper inner core wear out failure at the problems referred to above, the replaceable interior core assembly formula vibration damper that original vibration damper shell still can continue to use.

Task of the present utility model is finished as follows: under original vibration damper and existing entrucking connecting mode and size constancy situation, changing vibration damper cover top portion and gland welding connecting mode is scyewed joint, and the vibration damper inner core is contained by the concentric cylinder housing, this concentric cylinder housing bottom is shut, top compresses the inner core oil sealing and constitutes replaceable interior core assembly, between assembly top and frame, be provided with setting sleeve, have rubber washer in the gland, gland and inner core piston cooperation place are provided with dustproof cushion rubber.

The utility model frame and gland adopt scyewed joint, can conveniently take out when inner core is damaged, and more renew inner core, former shell continues to use, the employing inner core is contained by the concentric cylinder housing and is equipped with setting sleeve, and assembling need not centering, unbalance loading can not occur, improve working life, reduce manufacture cost, the utility model not only can industrialized mass production, also can reequip existing vibration damper, performance is constant, and cost saving is apparent.

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

Fig. 1 is the utility model overall structure figure

With reference to accompanying drawing 1, under original vibration damper and existing entrucking connecting mode and size constancy situation, changing vibration damper shell [1] top and gland [2] welding connecting mode is scyewed joint, and the vibration damper inner core is contained by concentric cylinder housing [3], this concentric cylinder housing bottom is shut, top compresses the inner core oil sealing and constitutes replaceable interior core assembly, between assembly top and frame, be provided with setting sleeve [7], have rubber washer [4] in the gland [2], gland [2] is provided with dustproof cushion rubber [6] with inner core piston [5] cooperation place.

Claims

1, a kind of replaceable interior core assembly formula vibration damper, it is by rubber washer [4], inner core piston [5], dustproof cushion rubber [6] constitutes, it is characterized in that: under original vibration damper and existing entrucking connecting mode and size constancy situation, changing vibration damper shell [1] top and gland [2] welding connecting mode is scyewed joint, and the vibration damper inner core is contained by concentric cylinder housing [3], this concentric cylinder housing bottom is shut, top compresses the inner core oil sealing and constitutes replaceable interior core assembly, between assembly top and frame, be provided with setting sleeve [7], have rubber washer [4] in the gland [2], gland [2] is provided with dustproof cushion rubber [6] with inner core piston [5] cooperation place.
