Abstract
The utility model provides a porous type regulation connecting rod. Including the connecting rod body, the connecting rod body articulates at the support epaxially, the connecting rod body be middle wide, the narrow structure in both ends, be provided with a prominent minor axis in the middle of the connecting rod body, connecting rod body right -hand member is the hinged end, is provided with the mounting hole of a step form, installs ball bearing in the mounting hole, through ball bearing and support hub connection, connecting rod body left end be provided with one with the mounting hole of right -hand member mounting hole opposite direction's step form, install ball bearing in the mounting hole, connecting rod body left side extend and have an upwards handle of perk, be provided with spacing hole on the handle. The utility model discloses simple structure has better rotation capability, swings more smoothly, can prevent that the card dies, improves the factor of safety of door, reduces the human accident incidence.
Description
Technical field
The utility model relates to technical field of automobile parts, is specifically related to a kind of porous type regulating connecting rod be applied on racing car car door.
Background technology
Motor sport plays spacing the present existing history more than 100 years.Motor sport is divided into two large class, track cycle and non-track cycles.Racing car must formulate according to Federation Internationale de I' Automobile the formula manufacture that the formula issued specifies, comprises the Distance geometry size etc. of body construction, length and width, minimum weight, engine displacement, number of cylinders, tank capacity, electronic machine, tire.
In motor sport, except the domain to vehicle, power system, control system has outside strict regulation, also has strict requirement to the structure of Vehicular door.Current Vehicular door, general employing tie-bar support structure, in actual use, racing car is in violent motion and vibration processes, easily there is infinitesimal deformation in the hinge point of connecting rod, affects the normal rotation work of connecting rod, if run into emergency situation, likely car door cannot be opened, and causes personnel's accident.
Therefore need to design a kind of new connector of car door.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency for above-mentioned existence, provides a kind of structure simple, has better rotating property, swing more smooth, prevent stuck, improve the safety factor of car door, reduce the porous type regulating connecting rod of personnel's accident rate.
The utility model solves the technical scheme that its technical matters adopts:
Porous type regulating connecting rod, includes con-rod only, and con-rod only is hinged on bearing axle, it is characterized in that, described con-rod only is middle wide, the structure that two ends are narrow; Be provided with the minor axis of a projection in the middle of con-rod only, con-rod only right-hand member is pin jointed end, is provided with a step-like mounting hole, is provided with ball bearing of main shaft, is connected by ball bearing of main shaft with bearing axle in mounting hole; Described con-rod only left end is provided with a step-like mounting hole contrary with right-hand member mounting hole direction, is provided with ball bearing of main shaft in mounting hole; Extend on the left of described con-rod only and have a handle be upturned, handle is provided with spacing hole.
In such scheme, be interference fit between described ball bearing of main shaft and mounting hole, form fastening structure, the outer ring of ball bearing of main shaft is fixed, and inner ring is rotatable.
In such scheme, described con-rod only is also evenly distributed with multiple through hole, the pore size of through hole is all identical, and is less than the aperture of mounting hole.
Principle of the present utility model is: utilize being connected between ball bearing of main shaft and axle, replaces hinged, can play better revolute pair effect, and has offered multiple through hole, alleviates the weight of connecting rod.
Technical advantage of the present utility model is:
The utility model structure is simple, has better rotating property, swings more smooth, can prevent stuck, improves the safety factor of car door, reduces personnel's accident rate.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment con-rod only structural representation;
In figure: 1 con-rod only, 2 first mounting holes, 3 second mounting holes, 4 spacing holes, 5 through holes.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is further described:
Porous type regulating connecting rod as shown in Figure 1, includes con-rod only 1, and con-rod only 1 is hinged on bearing axle, and described con-rod only 1 is middle wide, the structure that two ends are narrow; Be provided with the minor axis of a projection in the middle of con-rod only 1, con-rod only 1 right-hand member is pin jointed end, is provided with in step-like first mounting hole 2, first mounting hole 2 and is provided with ball bearing of main shaft, be connected by ball bearing of main shaft with bearing axle; Described con-rod only 1 left end is provided with in second step-like mounting hole 3, second mounting hole 3 contrary with the first mounting hole 2 direction and is provided with ball bearing of main shaft; Extend on the left of described con-rod only 1 and have a handle be upturned, handle is provided with spacing hole 4.
In the present embodiment, be interference fit between described ball bearing of main shaft and mounting hole, form fastening structure, the outer ring of ball bearing of main shaft is fixed, and inner ring is rotatable.
In the present embodiment, described con-rod only 1 is also evenly distributed with multiple through hole 5, the pore size of through hole 5 is all identical, and is less than the aperture of mounting hole.
More than illustrate and be only Application Example of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalence change that the utility model claim is done, still belong to protection domain of the present utility model.
