Including base body, base body be flat massive structure, one side indent of base body has a lump formation neck, the base body both sides be provided with a mounting groove respectively, the mounting groove is enclosed slot, its shape is rectangular hole groove form, base body in the middle of be provided with two inside side by side for the mounting hole of step form, the mounting hole is upper and lower two -layer for the through -hole divide into, lower floor's diameter is little, upper diameter is big, installs ball bearing in the upper strata. 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 Transmission base 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 Transmission base of personnel's accident rate.
The utility model solves the technical scheme that its technical matters adopts:
Racing car car door Transmission base, includes base body, it is characterized in that, described base body is flat block structure, and the side indent of base body has one piece to form neck; Described base body both sides are respectively arranged with a mounting groove, and mounting groove is enclosed slot, and its shape is strip hole channel-shaped; Being set side by side with two inside in the middle of described base body is step-like mounting hole, and 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, is provided with ball bearing of main shaft in upper strata.
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, the neck finish of described base body is also provided with a spacing hole, and available pin is spacing by base body, prevents from swinging.
Principle of the present utility model is: on base body, arrange mounting hole, utilizes 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 base body, 2 mounting holes, 3 spacing holes, 4 mounting grooves.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is further described:
Racing car car door Transmission base, includes base body 1 as shown in Figure 1, and described base body 1 is flat block structure, and the side indent of base body 1 has one piece to form neck; Described base body 1 both sides are respectively arranged with a mounting groove 4, and mounting groove 4 is enclosed slot, and its shape is strip hole channel-shaped; Being set side by side with two inside in the middle of described base body 1 is step-like mounting hole 2, and 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, is provided with ball bearing of main shaft in upper strata.
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, the neck finish of described base body 1 is also provided with a spacing hole 3, and available pin, by spacing for base body 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.
