Abstract
The utility model provides a be used for driven arc -shaped connection rod. Including the connecting rod body, the connecting rod body articulates at the support epaxially, the connecting rod body for the prominent arc structure that makes progress, be provided with the mounting hole of describing for the step inside in the middle of the connecting rod body, the mounting hole is the blind hole, installs a ball bearing in the mounting hole, through a ball bearing and support hub connection, connecting rod body left side still is provided with one and the protruding axle of connecting rod plane vertically, and protruding epaxial cover has the 2nd ball bearing. 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 curved rod for transmission 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 l'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, tankage, electronic equipment, tire.
In motor sport, except the domain to vehicle, dynamical 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 micro-strain in the hinge point of connecting rod, affects the normal rotation work of connecting rod, if run into emergency, 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 racing car car door fork of personnel's accident rate.
The utility model solves the technical scheme that its technical problem adopts:
For the curved rod of transmission, include con-rod only, con-rod only is hinged on bearing axle, it is characterized in that, described con-rod only is arcuate structure upwardly; Being provided with an inside in the middle of con-rod only is step-like installing hole, and installing hole is blind hole, is provided with the first ball bearing in installing hole, is connected with bearing axle by the first ball bearing; Also be provided with a convex axle vertical with linkage plane on the left of con-rod only, on convex axle, cover has the second ball bearing.
In such scheme, be interference fit between the first described ball bearing and installing hole, form fastening structure, the outer ring of ball bearing is fixed, and inner ring is rotatable.
In such scheme, the inner ring of the second described ball bearing is fixed, and outer ring is rotatable.
In such scheme, the peak place of described con-rod only projection arc, is also provided with a spacing hole, can inserts pin con-rod only is spacing, prevents from swinging.
Principle of the present utility model is: utilize being connected between ball bearing and axle, replaces hinged, can play better revolute pair effect.
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 installing holes, 3 spacing holes, 4 convex axles.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is further described:
As shown in Figure 1 for the curved rod of transmission, include con-rod only 1, con-rod only 1 is hinged on bearing axle, and described con-rod only 1 is arcuate structure upwardly; Being provided with an inside in the middle of con-rod only 1 is step-like installing hole 2, and installing hole 2 is blind hole, is provided with the first ball bearing in installing hole 2, is coupling by the first ball bearing and bearing; Also be provided with a convex axle 4 vertical with linkage plane on the left of con-rod only 1, on convex axle 4, cover has the second ball bearing.
In the present embodiment, be interference fit between the first described ball bearing and installing hole 2, form fastening structure, the outer ring of ball bearing is fixed, and inner ring is rotatable.
In the present embodiment, the inner ring of the second described ball bearing is fixed, and outer ring is rotatable.
In the present embodiment, the peak place of described con-rod only 1 projection arc, is also provided with a spacing hole 3, can insert pin by spacing for con-rod only 1, prevents from swinging.
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.
