Abstract
The utility model relates to a piston without a pin, which belongs to the field of traffic transportation machinery. The utility model is suitable for a rack bar and gear driven internal combustion engine. The major technique of the utility model is that a rack bar and a polished rod are in an integrity. A piston and the polished rod are in an integrity, and the connecting position of the polished rod and the piston is provided with a reinforced connecting platform. The rack bar, the polished rod and the piston are made into an integrity, so a piston pin is saved, and the cost is reduced.
Description
The utility model belongs to the transportation machinery field, is applicable to the internal-combustion engine of rack pinion transmission.
The piston of motor all is to be joined by wrist pin and connecting rod, and (application number: 992154820), the swing to-and-fro motion that has changed connecting rod is straight reciprocating motion, and tooth bar promptly is a connecting rod owing to the internal-combustion engine that the rack pinion transmission has been arranged.Because the invention of the internal-combustion engine that rack pinion passes, feel wrist pin be one more than part, therefore improving the existing piston structure seems necessary.
Invention does not have the purpose of pin piston model utility will simplify structure of piston exactly, reduces cost.
It is one that artificer of the present utility model adopts tooth bar and polished rod, and piston and polished rod are one, and polished rod has one to strengthen being connected platform with the piston joint.
The utility model major advantage is to have simplified piston structure, has omitted wrist pin, has reduced cost.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is a cross-sectional schematic of the present utility model.
Describe details of the present utility model and working condition in detail below in conjunction with Fig. 1.
Tooth bar (1) is an one with polished rod (2), piston (3) is again to be one with polished rod, polished rod has one to strengthen being connected platform (5) with the joint of piston, have the groove (4) of drain the oil ring, piston ring on the face of the outer garden of piston, the integral body of not having a pin piston both can foundry goods, also forging then forms by machining.Simultaneously, polished rod and piston also can be made split, are exactly at the skirt section of piston end, directly cast out a step, and screw thread is arranged on the step, and also there is screw thread the end of polished rod, connects with screw thread.Also can connect the platform place and make screw thread, use screwed connection in reinforcement.Because tooth bar, polished rod, piston are made integral body, therefore just economized wrist pin, thereby reduced cost.
Claims (1)
- A kind of no pin piston is characterized in that: tooth bar (1) is an one with polished rod (2), and piston (3) is an one with polished rod, and polished rod has one to strengthen being connected platform (5) with the piston joint.
