Abstract
The utility model relates to a built-up crankshaft of a gas engine used for a small car, which comprises a built-up crankshaft composed of a monomeric crank, a bolt crank pin and a nut, oil-holes are drilled in the bolt crank pin and a crank, wherein, the oil outer margin of the crank is provided with a splashing oil hole, a throttle is installed at the splashing oil hole through a tapered thread, so as to prevent causing pressure discharge for the lubricant of crank pin. The built-up crankshaft has simple structure and low cost, and is propitious to be used for the gas engine of the small car.
Description
Technical field
The utility model belongs to engine technology, is specifically related to the crankshaft structure of small-sized Vehicular internal combustion engine.Be used to improve the motor car engine assembly process process and reduce cost.
Background technique
Traditional automobile internal machine crankshaft substantially all is to adopt integrated type, its processing technology complexity.And large-scale marine engine has the employing vuilt-up crankshaft, but its mode of structure is not suitable for small-sized car combustion engine.
Summary of the invention
The utility model proposes a kind of motor car engine vuilt-up crankshaft at the deficiency that prior art exists, new structure simple, easy to operate, with low cost, be suitable for small-sized Vehicular internal combustion engine.
The technical solution of the utility model is as follows:
A kind of small-sized Vehicular internal combustion engine vuilt-up crankshaft, it is made up of two monomer crank throws, bolt crank pin and nut, two monomer crank throws are connected with the nut symmetry by the bolt crank pin, in bolt crank pin and two monomer crank throws, all be drilled with oilhole, and their oilholes are interconnected, oily outer rim at two monomer crank throws has the oilhole that splashes, and the throttle valve of band tapered thread is installed at the oilhole place of splashing, and rushes down pressure to prevent from crank pin lubricant oil caused.
This vuilt-up crankshaft is simple in structure, with low cost, is suitable for small-sized Vehicular internal combustion engine.
Description of drawings
Fig. 1 is the structural representation of this vuilt-up crankshaft;
Fig. 2 is the structural representation of monomer crank throw;
Fig. 3 is the structural representation of bolt crank pin.
Embodiment
Referring to Fig. 1, this vuilt-up crankshaft is made up of two monomer crank throws 1, bolt crank pin 2 and nut 3, two monomer crank throws 1 are connected with nut 3 symmetries by bolt crank pin 2, in bolt crank pin 2 and two monomer crank throws 1, all be drilled with oilhole 4, and their oilhole 4 is interconnected, oily outer rim at two monomer crank throws has the oilhole 5 that splashes, and the throttle valve 6 of band tapered thread is installed at oilhole 5 places of splashing, and rushes down pressure to prevent from crank pin lubricant oil caused.
