Abstract
A piston-connecting rod module with small size, light weight and long service life for car is disclosed. Said piston has a holder for the end of connecting rod and the radial fixing holes for supporting bridges (one for one). Said bridge has the lateral pins at its both ends for being inserted in said fixing holes and a lateral connecting-rod pin body at its middle. A connecting rod has a pin body hole at its end for matching with said connecting-rod pin body.
Description
Technical field
The invention belongs to piston and connection rod set component.
Background technique
Piston rod part in the known technology, its connecting rod radially connecting pin on piston directly is connected with piston, because connecting pin need bear powerful stamping press, so this connecting pin is made quite thickly, its weight is also big.General its front portion of piston is a hermetic unit, and the rear portion then is called the skirt section and play the guiding role.Button is provided with seal ring and oil ring on the hermetic unit perisporium, and connecting pin is located at the skirt section of piston.Owing to be provided with thick connecting pin, just need there be big relatively axial dimension in the skirt section, thereby makes whole piston axial dimension become big, the corresponding increase of weight, and this is unfavorable for that machinery is to small and exquisite, agile, speed up development.
Summary of the invention
The present invention will solve that known piston link assembly piston axial dimension is big, and weight is big, and the connecting rod swing loss is big, is unfavorable for that machinery to problem small and exquisite, agile, the speed up development, provides a kind of piston rod part of the present invention for this reason.
For addressing the above problem, on piston, be connected with connecting rod in the technical solution used in the present invention, its special way is to be provided with connecting-rod head seat chamber and bridge radially holds fixed hole on described piston, fixed hole is held through described bridge in the piston both sides, and each embeds and has a bridge to hold;
Bridge holds its main body and is provided with and can inserts described bridge to hold the lateral pin of fixed hole prominent, and bridge holds the connecting rod shank that the middle part is provided with a side direction;
Its end of described connecting rod is provided with in this shank hole, shank hole and is plugged with the connecting rod shank that described bridge holds.
The present invention can be provided with the cooling vallecular cavity on piston.
Can be provided with the connection pin-and-hole on the connecting rod shank that described two bridges hold, the also middle intercalation of this connecting pin has the shank of connection to make two bridges hold relative positioning.
After two bridges hold and radially insert from the piston both sides respectively, hold the outside at bridge and establish snap ring and make it to take off outside not with piston is fixing.
The connecting rod shank that bridge holds inserts the shank hole of interlinking lever end, connecting rod and bridge is held interconnect.
Interlinking lever end is located in the connecting-rod head seat chamber of piston, is encased inside bearing shell between interlinking lever end and connecting-rod head seat chamber, then is common-sense.
The present invention is owing to be provided with bridge and hold the prominent bridge that is inserted in piston of its lateral pin and hold fixed hole, and bridge holds and can be positioned at the cavity position that piston can be offered relatively, bridge holds establishes the shank hole that the connecting rod shank is inserted in interlinking lever end, when connecting rod draws the piston operation, by bridge hold transmit stressed, when piston, connecting rod promote mutually, the two is directly stressed, so the present invention has exempted the connecting pin that uses thick heaviness, the piston axial dimension is greatly reduced, the weight of assembly then alleviates significantly, and the swing energy of connecting rod also can reduce, and it is more small and exquisite, efficient that machinery will become; The height and position of piston among the present invention in cylinder is lower, inner top surface can be open substantially, like this, machine oil that splashes in the crankcase and moving air, cooling piston to greatest extent, simultaneously, the piston inner top surface can make up one or more cooling chambers, can further take away the heat that piston heart portion assembles by the machine oil that connecting rod imports, guarantee the stable of assembly thermal performance.

Be labeled as among the figure: 1 piston, 2 snap rings, 3 bridges hold, and 31 connect pin-and-hole, and 32 pins are prominent, 33 connecting rod shanks, 4 bearing shells, 5 connecting rods, 6 connecting pins, 7 oil grooves, 8 cooling vallecular cavities, 9 bridges hold fixed hole, 10 connecting-rod head seat chambeies.
Embodiment
Piston rod part, piston 1 are provided with connecting-rod head seat chamber 10 and bridge radially holds fixed hole 9, and fixed hole 9 each embedding are held through described bridge in piston 1 both sides has a bridge to hold 3; Bridge holds 3 its main body two ends and respectively is provided with one and can inserts described bridge to hold the lateral pin of fixed hole 9 prominent 32, and bridge holds connecting rod shank 33 that 3 middle parts are provided with a side direction and which is provided with one and connect pin-and-hole 31; Connecting rod 5 its ends are provided with in this shank hole, shank hole and are plugged with the connecting rod shank 33 that described bridge holds, and intercalation has connecting pin 6 in the connection pin-and-hole 31 that bridge holds; Piston 1 is provided with cooling vallecular cavity 8; Be provided with oil groove 7 in the connecting rod.
In this example, two bridges hold Zhong Yiqiao and hold with above-mentioned identical, another bridge holds and changes the connection shank 33 on it into tenon and can insert the connection pin-and-hole 31 that a described bridge holds, and substitutes connecting pins 6 thereby this tenon effect is equivalent to described connecting pin 6, and this two bridge holds and can be described as " male and female " bridge and hold.
Do not establish connection pin-and-hole and interior connecting pin thereof on the connecting rod shank that two bridges hold in this example, and make two bridges hold relative positioning at the external sleeve that is arranged with of two link pins.
