Abstract
The utility model discloses a front wheel turning device of the motor vehicle, belonging to motor vehicle fittings technical field, which is characterized in comprising a front axle, a wheel hub moveably connected with the front axle, a cross bar, a link arm connecting the cross bar with the wheel hub; wherein, the cross bar are double and positioned in front of the axle; the outer side of the two cross bars is connected with the link arm and the inner side of the two cross bars is connected with a connecting plate fixed in front axle through a pin. As an improvement of the utility model, the connecting plate is regular triangle. The utility model solves the problem of steering-constrained caused by the location of axle and can be extensively applied to all sorts of motor vehicle.
Description
Technical field
The utility model belongs to the motor vehicle fittings technical field, relates in particular to a kind of front wheels of motor-vehicles turning device.
Background technology
The turning device that uses on front wheels of motor-vehicles at present adopts cross bar to be positioned at the front axle rear side mostly, be connected with wheel hub by trapezoidal connecting arm, form one pre-large post-small trapezoidal, like this, when self-propelled vehicle is turned, the rotational angle of motor turning one side front-wheel had both guaranteed the harmony of left and right wheels when self-propelled vehicle is turned greater than the angle that the opposite side front-wheel rotates; Guaranteed again cross bar not with the tire friction.But, for some vehicle, as: the vehicle of servo-actuated lift bridges such as truck, trailer, if cross bar is positioned at the rear side of front axle, because wheelbase is nearer, the corner that out of reach requires during turning, it is limited to cause self-propelled vehicle to turn.If cross bar is put into front axle the place ahead, the angle that the rotational angle of motor turning one side front-wheel rotates greater than the opposite side front-wheel in order to guarantee to turn, the coordination of two front-wheels when self-propelled vehicle is turned, cross bar must extend, cause the length of the length of cross bar greater than front axle, cross bar will withstand on the tire, and self-propelled vehicle can't be moved ahead and turn.
The utility model content
Problem to be solved in the utility model just provides and a kind ofly is not subjected to wheelbase restriction, can be applicable to various model vehicles and rotates front wheels of motor-vehicles turning device easily.
For addressing the above problem, the technical scheme that the utility model front wheels of motor-vehicles turning device adopts is: comprise front axle, with wheel hub, the cross bar of front axle flexible connection and be connected cross bar and the connecting arm of wheel hub, described cross bar is two, and be positioned at the place ahead of front axle, the external side end of two cross bars is connected with connecting arm, and the medial extremity of two cross bars is connected with the connecting panel pin that pin is fixed in front axle.
Its additional technical feature is: described connecting panel is a triangle, an one summit is connected with preceding pivot pin, the summit that is positioned at this connecting panel left side is connected with the cross bar pin that is positioned at the connecting panel right side, and the summit that is positioned at this connecting panel right side is connected with the cross bar pin that is positioned at the connecting panel left side; Described connecting panel is an equilateral triangle.
Front wheels of motor-vehicles turning device provided by the utility model compared with prior art has the following advantages: one, because cross bar is positioned at the place ahead of front axle, be not subjected to the restriction of axletree position, and therefore, be applicable to the vehicle of various models; They are two years old, because cross bar is two, and be connected with the triangle connecting plate pin, when turning to the left, the left side cross bar drives the bearing pin of connecting panel on front axle and rotates, and the front-wheel that drives the right side rotates to the left, but, since the effect of connecting panel, the distance that the distance that the left side cross bar is moved to the left is moved to the left greater than the right side cross bar, and promptly the angle of left side front-wheel rotation is greater than the angle of right side front wheel rotation; In like manner, when turning to the right, the angle that right side front wheel is rotated is greater than the angle that the left side front-wheel rotates, and left side wheel and right-hand wheel is harmonious when having reached the self-propelled vehicle turning.
Description of drawings
Accompanying drawing is the structural representation of the utility model front wheels of motor-vehicles turning device.
The specific embodiment
Be described in further details below in conjunction with the concrete structure and the use principle of accompanying drawing the utility model front wheels of motor-vehicles turning device.
As shown in drawings, the utility model front wheels of motor-vehicles turning device comprises front axle 1, be connected with left side wheel hub 2 and right side wheels hub 3 at the front axle two ends, (left side in the presents, right side and the place ahead, rear are with respect to the driver) is at the preceding square cotter fixed connecting plate 4 of front axle, connecting panel 4 is an equilateral triangle, and an one summit is fixing with itself and front axle 1 pin by first set pin 5.Cross bar is two, is respectively left side cross bar 7 and right side cross bar 6, and the left side of connecting panel 4 is connected with right side cross bar 6 pins, and the right side of connecting panel 4 is connected with left side cross bar 7 pins; The other end of left side cross bar 7 and right side cross bar 6 is connected with right side wheels hub 3 with left side wheel hub 2 with right connecting arm 9 by left connecting arm 8.
Certainly, connecting panel 4 can be the triangle of other shapes, also can wait other shapes for circle or ellipse.
When self-propelled vehicle is turned to the left, when left side cross bar 7 turns left, driving connecting panel 4 rotates around the set pin on the front axle 5, right side cross bar 6 drives right side wheels hub 3 and rotates to the left, since the effect of connecting panel 4, the angle that the angle that left side wheel hub 2 rotates is rotated greater than right side wheels hub 3; In like manner, when turning to the right, the angle that right side wheels hub 3 rotates is greater than the angle that left side wheel hub 2 rotates, and reached the coordination of left side wheel hub 2 and right side wheels hub 3 when self-propelled vehicle is turned.
Claims (3)
1, front wheels of motor-vehicles turning device, wheel hub, the cross bar that comprises front axle, flexibly connects with front axle and be connected cross bar and the connecting arm of wheel hub, it is characterized in that: described cross bar is two, and be positioned at the place ahead of front axle, the external side end of two cross bars is connected with connecting arm, and the medial extremity of two cross bars is connected with the connecting panel pin that pin is fixed in front axle.
2, front wheels of motor-vehicles turning device according to claim 1, it is characterized in that: described connecting panel is a triangle, an one summit is connected with preceding pivot pin, the summit that is positioned at this connecting panel left side is connected with the cross bar pin that is positioned at the connecting panel right side, and the summit that is positioned at this connecting panel right side is connected with the cross bar pin that is positioned at the connecting panel left side.
