Abstract

The utility model provides a servo-steering device for straddle-type single-rail vehicle servo-steering devices. An integral steering device is arranged on both sides of walking wheels of a vehicle capable of running PC beam of a light rail. The steering device consists of two steering wheels separately arranged on both sides and connected with each other through a turn arm connection rod, wherein the two steering wheels are respectively connected with both sides of the walking wheels through steering cranks. When in use, the steering wheels on both sides are tightly attached to two guide surfaces on both sides of the PC beam of the light beam. When the vehicle is in operation, the steering wheels and the walking wheels can adjust the walking wheels to turn the direction along the PC beam in a flexible parallelogram manner through hinged pins, thereby achieving less left-right wobble during operation of the vehicle, balanced force on the tires and less abrasion, and ensuring the stable high-speed operation state.

Description

Follower steering device of straddle-type single-track vehicle

Technical field

The utility model relates to a kind of steering hardware of straddle-type single-track vehicle, a kind of specifically follower steering device of straddle-type single-track vehicle.

Background technology

At present, urban light rail PC girder span type monorail vehicle all adopts elasticity turning around a curve device, what adopt is to turn to by the track adjusting wheel that spring is installed on the car body, during horizontal applied force that the horizontal applied force that is subjected to when a certain side track adjusting wheel during vehicle operating is subjected to greater than the opposite side track adjusting wheel, under the effect of initial tension of spring, vehicle moves to this lateral deviation, the horizontal force rebalancing that is subjected to until the both sides track adjusting wheel, vehicle comes back in the middle of the circuit, in the whole process that appears at vehicle operating that this phenomenon can be gone round and begun again; When bigger curve appearred in circuit, the inboard track adjusting wheel of curve was subjected to bigger horizontal force, and spring is compressed, and outside track adjusting wheel can be left spigot surface, and inboard track adjusting wheel promotes the walking wheel slippage, realizes Vehicular turn; Use the vehicle of this elastic guide structure, when low cruise tire deflect and not obvious, but when high-speed cruising the deflecting of tire with fairly obvious, both be unfavorable for the vehicle safety operation, also cause Tyte Wear easily.

Summary of the invention

The utility model provides a kind of follower steering device of straddle-type single-track vehicle, and when vehicle was moved on light rail PC beam, circuit both sides track adjusting wheel was not left spigot surface all the time, can guarantee that vehicle follows line characteristics all the time and keep follow-up steering flexibly.

The utility model comprises walking wheel, and the technical scheme that is adopted is: the straddle-type single-track vehicle that can move on light rail PC beam, the Integral steering device is equipped with in the both sides of its walking wheel.

Described steering hardware is hinged for whole by pivot pin and connecting lever pipe link between the wheel flutter of the left and right sides, and two wheel flutters are rigidly connected with walking wheel respectively by turning to crank arm.The integral body of Gou Chenging can guarantee that the width between centers of wheel flutter is constant thus, makes it to be close to all the time the spigot surface of PC beam, and transfers away the steering effort distance of road wheel.

Described steering hardware is hinged on the connecting panel of car body below by pivot pin.Because turning member all is hinged on the connecting panel of car body below, constituted the lever motion structure of parallelogram, can one common peripheral realize turning to around the curve of PC beam.

During running condition, wheel flutter is close to the PC beam all the time under the drive of walking wheel spigot surface moves forward and backward, under the counteraction of PC beam spigot surface, rotate flexibly simultaneously by pivot pin, and by turning to the drive walking wheel of cranking arm to follow rotation, each wheel flutter, walking wheel rotate under the constraint of connecting lever pipe link synchronously, realize that with this vehicle follows the follow-up steering of route feature.

The utility model is by adopting said structure, solved single-track vehicle employing elastic guide in the prior art, beat periodically appears easily and track adjusting wheel is left PC beam spigot surface during by curve problem, the follow-up steering structure that it is flexible, stable, fully used the lever principle on parallel four limits, can make travelled by vehicle wheel under the situation of high-speed cruising, all the time along the spigot surface track follow-up steering of PC beam, the utlity model has flexible, stable steering feature, and can reduce Tyte Wear.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model running condition structural representation.

Fig. 3 is that the utility model walking wheel and wheel flutter place PC beam top side view of the state.

Among the figure: 1, wheel flutter, 2, the connecting lever pipe link, 3, walking wheel, 4, turn to and crank arm, 5, connecting lever, 6, pivot pin, 7, light rail PC beam, 8, connecting panel.

The specific embodiment

Shown in Fig. 1 embodiment: the straddle-type single-track vehicle that can on light rail PC beam 7, move, the Integral steering device is equipped with in the both sides of its walking wheel 3, steering hardware is hinged for whole with connecting lever pipe link 2 by pivot pin 6 between the left and right sides wheel flutter 1, two wheel flutters 14 are rigidly connected with walking wheel 3 respectively by turning to crank arm, and steering hardware is hinged on the connecting panel 8 of car body below by pivot pin 6.

Fig. 2, shown in 3: walking wheel 3 places the top of light rail PC beam 7, two wheel flutters 1 are close to respectively on the spigot surface of PC beam 7 both sides, during running state, walking wheel 3 is high-speed cruising on PC beam 7, drive both sides wheel flutter 1 is close to PC beam 7 both sides spigot surfaces and is moved forward and backward, when line characteristics changes, because the constraint of connecting lever pipe link 2, left and right sides wheel flutter 1 is close to the spigot surface operation all the time, pressing simultaneously the route feature under the reaction force acts of spigot surface rotates, and 4 drive walking wheels 3 and also rotate simultaneously, thereby guarantee walking wheel 3 orbiting motion on road along the line all the time by turning to crank arm.
