Abstract

The utility model discloses an adjustable front bridge trapezoidal spindle device in the field of vehicle steering devices. The adjustable front bridge trapezoidal spindle device comprises a front bridge, wherein two outer sleeves are vertically fixed at both ends of the front bridge; rotate shafts are arranged in the two outer sleeves in a matched manner and include straight segments and bending horizontal segments; wheels are arranged at the ends of the horizontal segments; two rotation arms arranged on the upper ends of the vertical segments; two ball joints are arranged at the other ends of the rotation arms; the ball joints on both sides of the front bridge are connected with each other through a draw bar; the draw bar, the front bridge and the two rotation arms are arranged in a trapezoidal form; an axial hole extending from top to bottom is formed on the vertical segment of the rotation shaft; a round nut is arranged in the axial hole; an inner sleeve is arranged in the axial hole above the round nut; the lower end face of the inner sleeve is matched with the upper end face of the round nut to form an inclined surface; the rotation arms are welded and fixed on the inner sleeve; and a screw shaft is arranged on the rotation arms and is engaged with the round nut through the inner sleeve. The adjustable front bridge trapezoidal spindle device can adjust the positions of the rotation shafts and the rotation arms according to requirements to suit four-wheel vehicles with different wheeltracks and wheelbases.

Description

The trapezoidal goat's horn device of adjustability propons

Technical field

The utility model relates to a kind of vehicle steering device, particularly the trapezoidal goat's horn steering hardware of the propons of four wheeler.

Background technology

In the prior art, the front-wheel steering of four-wheeled adopts the trapezoidal goat's horn steering hardware of a kind of propons, it mainly includes axle beam, and the axle beam two ends uprightly are fixed with outer tube, cooperates separately in two outer tubes rotating shaft is installed, rotating shaft is made up of the horizontal segment of vertical section and bending, the horizontal segment end is equipped with wheel, vertical section upper end and the welding of pivoted arm one end, and the pivoted arm other end is provided with bulb, be connected through pull bar between the bulb of axle beam both sides, described pull bar, axle beam and two pivoted arms are trapezoidal layout.During work, pull bar pulling two-wheeled turns to simultaneously, because the relation of trapezium structure, the angle that two-wheeled turns to is also inconsistent, can adapt to the needs of turning, avoids tire and ground cliding friction.Its weak point is: this steering hardware is because the difference of its wheelspan, wheelbase, and the angle between pivoted arm and the axle beam is all inequality, therefore, all needs different angles for disalignment apart from the vehicle of, wheelspan, and its commonality is poor; In addition, the distortion in the welding process also causes angle to change easily, and its setting accuracy is poor, can not adjust with the need.

The utility model content

The purpose of this utility model provides the trapezoidal goat's horn device of a kind of adjustability propons, and this device can be applied on the four-wheeled of different wheelspans and wheelbase.

The purpose of this utility model is achieved in that the trapezoidal goat's horn device of adjustability propons, include axle beam, the axle beam two ends uprightly are fixed with outer tube, cooperate separately in two outer tubes rotating shaft is installed, rotating shaft is made up of the horizontal segment of vertical section and bending, and the horizontal segment end is equipped with wheel, the vertical section upper end is provided with a pivoted arm, the pivoted arm other end is provided with bulb, is connected through pull bar between the bulb of axle beam both sides, and described pull bar, axle beam and two pivoted arms are trapezoidal layout; The vertical section of described rotating shaft is provided with the axial hole that extends from the top down, be placed with a circular nut in the axial hole, be positioned at the circular nut upside in the axial hole and be provided with inner sleeve, dip plane for cooperatively interacting between the upper surface of inner sleeve lower surface and circular nut, described pivoted arm and inner sleeve welding are fixing, and pivoted arm is provided with the threaded engagement that a screw axial passes inner sleeve and circular nut.

During adjustment, can unclamp screw rod, at this moment, circular nut can be in axial hole turned position, pivoted arm also can arbitrarily rotate, and when pivoted arm turns to correct position, keeps pivoted arm motionless, screw rod is locked, because the dip plane for cooperatively interacting between circular nut and the inner sleeve, in the process of screw rod locking, circular nut can rotate, and adjust to the position of matching with the inner sleeve lower surface, continue to tighten screw rod, along the dip plane slippage, make inner sleeve between inner sleeve and the circular nut, locking position between circular nut and the rotating shaft, like this, pivoted arm and rotating shaft are fixed in new position; Compared with prior art, the utility model can be adjusted the position of rotating shaft and pivoted arm with the need, and it is easy to adjust, makes this device can be applied on the four-wheeled that wheelspan, wheelbase have nothing in common with each other, and it has commonality, and this device is particularly useful on the small-sized four-wheeled.

Description of drawings

Fig. 1 is the utility model structural representation.

Wherein, 1 wheel, 2 axial holees, 3 outer tubes, 4 circular nuts, 5 rotating shafts, 6 dip plane, 7 inner sleeves, 8 screw rods, 9 pivoted arms, 10 bulbs, 11 pull bars, 12 axle beams.

The specific embodiment

As figure, be the trapezoidal goat's horn device of adjustability propons, include axle beam 12, axle beam 12 two ends uprightly are fixed with to cooperate separately in outer tube 3, two outer tubes 3 rotating shaft 5 are installed, rotating shaft 5 is made up of the horizontal segment of vertical section and bending, the horizontal segment end is equipped with wheel 1, and the vertical section upper end is provided with a pivoted arm 9, and pivoted arm 9 other ends are provided with bulb 10, be connected through pull bar 11 between the bulb 10 of axle beam 12 both sides, pull bar 11, axle beam 12 and two pivoted arms 9 are trapezoidal layout; The vertical section of rotating shaft 5 is provided with the axial hole 2 that extends from the top down, be placed with a circular nut 4 in the axial hole 2, be positioned at circular nut 4 upsides in the axial hole 2 and be provided with inner sleeve 7, dip plane 6 for cooperatively interacting between the upper surface of inner sleeve 7 lower surfaces and circular nut 4, pivoted arm 9 is fixing with inner sleeve 7 welding, and pivoted arm 9 is provided with the threaded engagement that a screw rod 8 axially passes inner sleeve 7 and circular nut 4.

During adjustment, can unclamp screw rod 8, at this moment, circular nut 4 can be in axial hole 2 turned position, pivoted arm 9 also can arbitrarily rotate, and when pivoted arm 9 turns to correct position, keeps pivoted arm 9 motionless, with screw rod 8 lockings, because the dip plane 6 for cooperatively interacting between circular nut 4 and the inner sleeve 7, in the process of screw rod 8 lockings, circular nut 4 can rotate, and adjust to the position of matching with inner sleeve 7 lower surfaces, continue to tighten screw rod 8,6 slippages along the dip plane between inner sleeve 7 and the circular nut 4 make inner sleeve 7, locking position between circular nut 4 and the rotating shaft 5, like this, pivoted arm 9 is fixed in new position with rotating shaft 5; This device can be applied on the four-wheeled that wheelspan, wheelbase have nothing in common with each other, and can adjust the angle between pivoted arm 9 and the rotating shaft 5 with the need.
