Abstract
Bent axle part of many link drives, it mainly include at least two through in the middle of one even axle journal looks be connected together, have the bent axle body in U -shaped groove separately, its characterized in that the U type grooves of two bent axles body are the orientation to be arranged on the contrary, and the bottom in U type groove is provided with columniform connecting rod neck separately, the type of a U separately tip outside of the two bent axles body transversely is provided with the cylindrical trunnion of evagination, U die bed portion two outsides end of the bent axle body is provided with inward one section at least transition circular arc, columniform connecting rod neck with the axle journal surface of cylindrical trunnion is provided with at least one deck quench -hardened case. It has rational in infrastructurely, convenient to use, reliable, and wear -resisting, the atress is even, high transmission efficiency for crankshaft journal atress in the motion is even, prevents the inhomogeneous wearing and tearing of easy production on its surface, thereby guarantees the transmission effect, ensures the characteristics such as output performance of engine.
Description
Technical field
The utility model relates to a kind of crankshaft component of multi link transmission, belong to the driving component technical field of motor.
Background technique
The multi link driving crank of motor is primarily of main journal and multiple connecting rod neck composition, and wherein main journal is arranged on cylinder body, and multiple connecting rod neck is connected with the big end hole of many connecting rods, and connecting rod small end hole and piston of automobile connect to form multiple slidercrank mechanism; Translate linear motion is rotary motion by described crank in the transmission process of motor, subject the acting in conjunction of periodically variable gas pressure, reciprocal inertia force and consequent moment of torsion, moment of flexure, therefore, it requires that bent axle has enough rigidity, fatigue strength and impact toughness; Each working surface lubrication is good, wear-resisting, and rotating inertia force system reaches good balance; But the crankshaft structure of motor design Shortcomings, makes crankshaft journal unbalance stress at the volley, the wearing and tearing that surperficial easy generation is uneven, thus makes transmission deleterious, will directly have influence on the performances such as the output torque of motor in the course of time.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provides a kind of rational in infrastructure, easy to use, reliable, wear-resisting, and uniform force, transmission efficiency is high, the crankshaft component of the multi link transmission that transmission is effective.
The purpose of this utility model has been come by following technical solution, a kind of crankshaft component of multi link transmission, it mainly comprise at least two that be connected together by connecting shaft neck in the middle of, with the bent axle body of respective U-groove bevel, the U-type groove of described two bent axle bodies is layout towards the opposite, the bottom of respective U-type groove is provided with columniform connecting rod neck, be horizontally arranged with the cylindrical spindle neck of evagination outside the respective U-shaped end one of described two bent axle bodies, U-shaped bottom two outboard end of described bent axle body is provided with at least one section of inside transition arc; The journal surface of described columniform connecting rod neck and described cylindrical spindle neck is provided with at least one deck quench-hardened case.
The utility model is preferably: two described bent axle bodies and connecting rod neck, main journal are all selected spheroidal graphite cast iron raw material, formed by integrally casting is shaping, after the journal surface of main journal and connecting rod neck is by quenching and tempering process, form described quench-hardened case.
The utility model is further preferably: journal surface depth of hardening zone 1.3 to the 3.0mm of described main journal and connecting rod neck, it is 45 to 52HRC that tempering hardness requires.
The utility model improves the one of prior art, it has rational in infrastructure, easy to use, reliable, wear-resisting, uniform force, transmission efficiency is high, make crankshaft journal uniform force at the volley, prevent the wearing and tearing that the easy generation on its surface is uneven, thus ensure transmission effect, guarantee the features such as the output performance of motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by accompanying drawing, the utility model is further introduced: shown in Fig. 1, the crankshaft component of a kind of multi link transmission described in the utility model, it is mainly comprised at least two and to be connected together by connecting shaft neck 1 in the middle of, with the bent axle body 3 of respective U-groove bevel 2, the U-type groove 2 of described two bent axle bodies 3 is in layout towards the opposite, the bottom of respective U-type groove 2 is provided with columniform connecting rod neck 4, the cylindrical spindle neck 5 of evagination is horizontally arranged with outside respective U-type groove 2 end one of described two bent axle bodies 3, bottom the U-type groove 2 of described bent axle body 1, two outboard ends are provided with inside at least one section of transition arc 6, the journal surface of described columniform connecting rod neck 4 and described cylindrical spindle neck 5 is provided with at least one deck quench-hardened case 7.
The utility model preferred embodiment is: two described bent axle bodies 3 and connecting rod neck 4, main journal 5 are all selected spheroidal graphite cast iron raw material, formed by integrally casting is shaping, after the journal surface of main journal 5 and connecting rod neck 4 is by quenching and tempering process, form described quench-hardened case 7.
Journal surface depth of hardening zone 1.3 to the 3.0mm of described main journal 5 and connecting rod neck 4, it is 45 to 52HRC that tempering hardness requires.
