Abstract

A steering mechanism used for a snow motorcycle belongs to the technical field of the vehicles and comprises a direction shaft rotationally arranged on a frame and a pair of horizontal pull rods connected with a sleigh. The steering mechanism is characterized in that the mechanism also comprises a direction-shaft steering apparatus which is arranged on the frame and connected with both the direction shaft and the pair of horizontal pull rods and is used for leading the upper end of the direction shaft to move toward the direction of the motorcycle head when the head is impacted. The steering mechanism has the advantages that when the snow motorcycle head and/or the sleigh is impacted, the direction-shaft steering apparatus leads the upper part of the direction shaft to move toward the direction of the motorcycle head to lead the moving direction of the direction shaft to be identical to the forward inclining direction of a driver under the impact so as to reliably prevent the direction shaft from hurting the body of the driver, with good safety.

Description

The steering hardware of ski type motorbike
Technical field
The invention belongs to technical field of transportation means, be specifically related to a kind of steering hardware of ski type motorbike.
Background technology
Known, ski type motorbike is both to have can be used as the vehicle, can be used as the snowfield special vehicle of the usefulness of travelling again.For example also disclosing in the Chinese patent literature at document has this type of vehicle, for example utility model patent Granted publication CN2832655Y recommends have a kind of travelling to use snow wagon, the steering hardware of the snow wagon of this kind structure comprises steering track rod (Reference numeral 34 of patent) and jociey stick (Reference numeral of patent is 4), steering track rod and jociey stick connect, and with two skis devices be that sledge connects.The existing shortcoming of this steering hardware is: when the head of vehicle and/or two skis device met with bump, application force was passed to jociey stick through steering track rod, makes the health direction motion of jociey stick towards chaufeur, thereby can cause the injury to chaufeur.
Also has a kind of ski type motorbike that comparatively generally uses at present, structure is by shown in Figure 3, the steering hardware of this ski type motorbike comprises an axis of orientation 1 and a pair of intermediate rod 2, there is shown and be arranged in the intermediate rod 2 that one of them sledge 3 side and a pair of sledge 3 connects, and intermediate rod 2 connects with axis of orientation 1.Chaufeur is a steering handle when operating to the right left with handgrip, drives correspondingly motion to the left or to the right of sledge 3 by the axis of orientation 1 that connects with handgrip so, uses the direct of travel of adjusting vehicle.Steering hardware on this ski type motorbike exists the problem to the chaufeur injury equally.For example, when the bump situation took place between the headstock of vehicle and/or sledge and the obstacle, axis of orientation 1 can and cause the chaufeur of causing injury towards the direction motion of chaufeur.That is to say, ski type motorbike in the prior art is when vehicle is clashed into, the axis of orientation 1 of steering hardware can take place and the corresponding direction motion of chaufeur, because when meeting with bump, under the effect of force of inertia, the direction that the health of chaufeur is usually expressed as to headstock leans forward, so only make axis of orientation 1 keep consistent with the forward lean direction of chaufeur promptly towards the motion of headstock direction, could avoid axis of orientation 1 to undermine the health of chaufeur effectively.
Summary of the invention
Task of the present invention is to provide a kind of and can avoids axis of orientation to injure the health of chaufeur when vehicle is clashed into effectively and use the steering hardware of the ski type motorbike that embodies safety.
Task of the present invention is finished like this, a kind of steering hardware of ski type motorbike, it comprises axis of orientation and the intermediate rod a pair of and that sledge connects that is located at rotationally on the vehicle frame, characteristics are: also include one and be located at and make the upper end of axis of orientation towards headstock direction travel direction axle steer device when the head of vehicle is clashed into described axis of orientation and described a pair of intermediate rod being used for of connecting mutually on the described vehicle frame, described axis of orientation steering hardware comprises the axis of orientation swing arm, the direction pull bar, the steering shaft swing arm, towing plate and steering shaft, the axis of orientation swing arm be fixed on described axis of orientation the lower end and with a client link of described direction pull bar, one client link of the other end of direction pull bar and steering shaft swing arm, and the other end of steering shaft swing arm and described steering shaft are fixed, one end of towing plate and a client link of described a pair of intermediate rod, and the sledge of the other end of a pair of intermediate rod and described sledge turns to goat's horn to connect, the other end of towing plate is fixed on the steering shaft and is positioned at the top of described steering shaft swing arm, the upper end of steering shaft is bearing on the upper mounted plate that is fixed in described vehicle frame front end rotationally, the lower end of steering shaft is bearing on the bottom plate that is fixed in the vehicle frame front end rotationally, wherein, on, it is corresponding up and down that bottom plate keeps.
In another specific embodiment of the present invention, one client link of described direction pull bar has one first to connect bulb, the other end is linked with one second and connects bulb, and first connects bulb is connected with described axis of orientation swing arm, and the second connection bulb is connected with described steering shaft swing arm.
Go back in the specific embodiment of the present invention, offer one first on the described direction pull bar adjustment hole is installed.
In another specific embodiment of the present invention, the described first installation adjustment hole is a spanner hole.
In another specific embodiment of the present invention, the upper end of described steering shaft by primary shaft bearing and hub setting on described upper mounted plate, and the second bearing seat hub setting is passed on described bottom plate in the lower end of steering shaft, and it is corresponding up and down that first, second bearing seat keeps.
In of the present invention and then specific embodiment, the position of described primary shaft bearing occupy the middle part of the length direction of described upper mounted plate, and the position of described second bearing seat occupy the middle part of the length direction of described bottom plate.
Also and then in specific embodiment, the length of described upper and lower fixing plate equates of the present invention.
In again of the present invention and then specific embodiment, each client link of described a pair of intermediate rod has one the 3rd to connect bulb, each other end is linked with one the 4th and connects bulb, wherein, the 3rd connects bulb turns to goat's horn to be connected with described sledge, and the 4th connection bulb is connected with described towing plate.
In again of the present invention and then specific embodiment, offer on the described a pair of intermediate rod and at the position placed in the middle of the length direction of each intermediate rod and be used for second adjustment hole being installed for what spanner was inserted.
The advantage of technical scheme provided by the present invention is: when the head of ski type motorbike and/or sledge when suffering the obstacle bump, ensure of the direction motion of the top of axis of orientation towards the headstock of snow wagon by the axis of orientation steering hardware, the direction that leans forward that the sense of motion that makes axis of orientation and the person of riding are taken place when Vehicular impact is consistent, thereby can prevent the cause injury person's of riding body of axis of orientation reliably, therefore have good safety.
