Abstract
The utility model provides a cycle racing door pendulum rod. Including the pendulum rod body, the pendulum rod body is installed at the support epaxially to can swing wantonly, the pendulum rod body be middle wide, the narrow structure in both sides to both sides are the button head structure, the pendulum rod body is the hinged end on the left, and the right is the swing end, and wherein the hinged end is provided with the mounting hole that described an inside for the step, and the mounting hole is two -layer from top to bottom for the through -hole divide into, and lower floor's diameter is little, and upper diameter is big, installs ball bearing in the upper strata, through ball bearing and support hub connection. The utility model discloses simple structure has better rotation performance, swings more smoothly, can prevent that the card dies, improves the factor of safety of door, reduces personnel accident rate.
Description
Technical field
The utility model relates to technical field of automobile parts, is specifically related to a kind of racing car car door fork for racing car of competing for speed.
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 racing car car door fork of personnel's accident rate.
The utility model solves the technical scheme that its technical matters adopts:
Racing car car door fork, includes fork body, and fork body is arranged on bearing axle, and can swing arbitrarily, it is characterized in that, described fork body is middle wide, the structure that both sides are narrow, and both sides are round end structure; The fork body left side is pin jointed end, and the right is swinging end, and wherein pin jointed end is provided with an inside is step-like mounting hole, it is two-layer up and down that mounting hole is that through hole is divided into, and lower floor's diameter is little, and upper strata diameter is large, in upper strata, ball bearing of main shaft is installed, is connected with bearing axle by ball bearing of main shaft.
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 fork body edges is also provided with a spacing hole, and available pin, by spacing for fork body, prevents from swinging.
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.
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 fork body construction schematic diagram;
In figure: 1 fork body, 2 mounting holes, 3 spacing holes.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is further described:
Racing car car door fork as shown in Figure 1, includes fork body 1, and fork body 1 is arranged on bearing axle, and can swing arbitrarily, and described fork body 1 is middle wide, the structure that both sides are narrow, and both sides are round end structure; Fork body 1 left side is pin jointed end, and the right is swinging end, and wherein pin jointed end is provided with an inside is step-like mounting hole 2, mounting hole 2 is two-layer up and down for through hole is divided into, and lower floor's diameter is little, and upper strata diameter is large, in upper strata, ball bearing of main shaft is installed, is connected with bearing axle by ball bearing of main shaft.
In the present embodiment, be interference fit between described ball bearing of main shaft and mounting hole 2, form fastening structure, the outer ring of ball bearing of main shaft is fixed, and inner ring is rotatable.
In the present embodiment, described fork body 1 edge is also provided with a spacing hole 3, and available pin, by spacing for fork body, 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.
