Abstract
The utility model discloses a differential lock power cylinder, which comprises a cylinder body, wherein spring seats are respectively arranged on the inner side walls of two ends of the cylinder body, a piston rod is also arranged in an inner cavity of the cylinder body, the left end of the piston rod is connected with the left spring seat, the right end of the piston rod penetrates through the cylinder body and the right spring seat and extends out of the cylinder body, springs are sleeved on the spring seats, a bushing is arranged at the left end of the cylinder body, an air inlet is formed in an upper part of the bushing, a retainer ring is arranged at the right end of the cylinder body, and a rubber leather cup is arranged between the contact surfaces of the left spring seat and the cylinder body. The differential lock power cylinder disclosed by the utility model is simple in structure design, convenient to operate, capable of effectively and rapidly operating through the piston rod and springs in the center of the cylinder body, not easy to damage and low in cost.
Description
Technical field
The utility model relates to a kind of differential lock ram, belongs to technical field of automobile parts.
Background technique
Soon, this thing of differential mechanism also just has been born thereupon after the birth of first automobile in the world, the meaning that its exists have only one can normal turn for automobile; The carriage both sides wheel in past is through a hard Spindle Links, so the rotating speed of the wheel of both sides is identical forever, because can't differential; Wheel inboard when turning also has sliding friction except rolling friction, the wheel of not bad carriage is that wood is done, and is wear-resisting ... In like manner automobile also has same problem when turning; If still adopt a hard Spindle Links; The parts such as tire of automobile will receive serious damage when turning so, and in order to address this problem, current automobile all is the design of two semiaxis; What two semiaxis were linked is exactly differential mechanism, has had differential mechanism also just to allow the both sides wheel that speed discrepancy is arranged.
The model utility content
For deficiency and the defective of alleviating existing technology, the purpose of the utility model is to provide a kind of differential lock ram, and the utility model structural design is simple, and is easy to operate, through the piston rod and the spring at cylinder body center, carries out work fast and effectively.
The utility model adopts following technological scheme to achieve these goals:
The differential lock ram comprises cylinder body, it is characterized in that: described cylinder body two ends madial wall is separately installed with spring seat; Described inner chamber of cylinder block also is provided with piston rod, and described piston rod left end connects the left spring seat, and the right-hand member of piston rod runs through cylinder body and right spring seat and stretches out outside the cylinder body; All be with spring on the described spring seat; Described cylinder body left end is provided with lining, and said lining top is provided with suction port, and described cylinder body right-hand member is provided with back-up ring.
Described differential lock ram is characterized in that: be provided with rubber cup between the surface of contact of described left spring seat and cylinder body.
The advantage of the utility model:
The utility model structural design is simple, and is easy to operate, through the piston rod and the spring at cylinder body center, carries out work fast and effectively, and not fragile, cost is low.
Description of drawings
The structural representation of Fig. 1 the utility model.
