Abstract
A front-wheel steering position-limit mechanism comprises a steering knuckle which is connected with a wheel hub sleeved with a tire through a bearing, a bilaterally symmetrical concave cavity is disposed on the steering knuckle and perpendicular to a tire center circle surface, wherein the concave cavity is provided with a front position-limit surface and a back position-limit surface which are symmetrical relative to a concave cavity central surface which is perpendicular or at an angle to the horizontal plane, a connecting shaft which can swing in a fanshaped manner between the front and back position-limit surfaces is pivotedly disposed in the concave cavity with an axis of the swing being an intersecting line of the tire center circle surface and the concave cavity central surface, and an outer end of the connecting shaft is fixedly connected with a front wheel rocker arm which connected with a frame. The beneficial effects are that the concave cavity is disposed on the steering knuckle and shaped directly through machining, and is high in machining precision, high in degree of bilateral symmetry and uniform in position-limit.
Description
Technical field
The utility model relates to the limiting steering mechanism on a kind of battery-driven car or the hub of motorcycle.
Background technology
Prior electric car or motorcycle front-wheel limiting steering mechanism are when forwarding end position to by front fork, and the positioning plate that welds on the limited post on the front fork and the vehicle frame contacts completion.This limiting steering mechanism to the positioning plate of vehicle frame welding and the requirement of the limited post symmetry on the front fork than higher.Vehicle frame upper limit plate is in different manufacturing procedures, to accomplish with limited post on the front fork, adds to be prone to man-hour produce Mismachining tolerance, also will produce accumulated error during assembling, when causing front-wheel steering about steering angle inconsistent.
Summary of the invention
In order to overcome the deficiency that exists in existing battery-driven car or the motorcycle front-wheel limiting steering mechanism, the utility model provides a kind of good front-wheel steering stop gear of symmetry that turns to.
The technical scheme that the utility model solves its technical matters is: a kind of front-wheel steering stop gear; Comprise a steering swivel; Said steering swivel is connected with a wheel hub that is with tire through bearing, and normal direction tire center disc also is concaved with a symmetrical cavity on the said steering swivel, and said cavity has prosodetic plane, back confined planes; Said prosodetic plane, the relative cavity longitudinal plane of symmetry of back confined planes symmetry, said cavity longitudinal plane of symmetry is vertical with horizontal surface or at an angle; Be pivoted in the described cavity one can be between prosodetic plane, back confined planes the connecting shaft of fan-shaped swing; The axis of oscillation of said connecting shaft is the intersection line of tire center disc and cavity longitudinal plane of symmetry; The outer end of said connecting shaft and a front-wheel rocking arm are affixed, and said front-wheel rocking arm connects vehicle frame.Described tire center disc is the left-right symmetric face of tire.Described prosodetic plane, the back confined planes can be the face that directly constitutes cavity, also can be on the limiting stopper with the connecting shaft contact surface.
A kind of preferred, said cavity longitudinal plane of symmetry becomes 60 ° ~ 80 ° angle with horizontal surface.In this angular range,, steering swivel becomes the steering tiller of respective angles on connecting, and can improve comfort and connecting shaft and be pivoted service life of structure.Described angle is big more, and structural rigidity is high more, but operability can reduce.
A kind of preferred, said cavity is located on the steering swivel below with the wheel hub point of connection.Design makes front-wheel rocking arm and rocking bar and the steering tiller that will be located on the steering swivel can not interfere like this, and reduces the center of vehicle.
The utility model is being assembled into into car with this mechanism with other parts in use; Also to load onto a steering tiller on the steering swivel of this mechanism; Rotate steering tiller and drive the relative vehicle frame left-right rotation of steering swivel with wheel hub; And connecting shaft to be connected on the vehicle frame through the front-wheel rocking arm be that relative vehicle frame is static; Both are that the cavity on the steering swivel rotates relative to connecting shaft, and connecting shaft runs into the prosodetic plane on the cavity, the greatest limit that the back confined planes then arrives left-right rotation when turning to a certain extent, and promptly the left and right sides limiting steering limit of motor bike or battery-driven car has arrived.
The beneficial effect of the utility model is that cavity is located on the steering swivel, is directly to pass through the cutting moulding, and working accuracy is high, and the left-right symmetric degree is high, and is spacing even.
Description of drawings
Fig. 1 is the scheme drawing of an embodiment of the utility model.
Fig. 2 is the A-A direction cross-sectional schematic of an embodiment of the utility model.
Fig. 3 is the running condition scheme drawing of the utility model.
Fig. 4 is the scheme drawing that connecting shaft arrives left and right sides confined planes among embodiment of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.
In conjunction with attaching Fig. 1 and 2 and 3; A kind of front-wheel steering stop gear comprises a steering swivel 1, and said steering swivel 1 is connected with a wheel hub 3 that is with tire 2 through bearing; Normal direction tire center disc 4 is concaved with a symmetrical cavity 5 on the said steering swivel 1; Said cavity 5 has prosodetic plane 6, back confined planes 7, said prosodetic plane 6, back confined planes 7 relative cavity longitudinal plane of symmetry 8 symmetries, and said cavity longitudinal plane of symmetry 8 is vertical with horizontal surface or at an angle; Be pivoted in the described cavity 5 one can be between prosodetic plane 6, back confined planes 7 connecting shaft 9 of fan-shaped swing; The axis of oscillation of said connecting shaft 9 is intersection lines of tire center disc 4 and cavity longitudinal plane of symmetry 8; The outer end of said connecting shaft 9 and a front-wheel rocking arm 10 are affixed, and said front-wheel rocking arm connects vehicle frame 11.Described tire center disc is the left-right symmetric face of tire.
In the present embodiment, said cavity longitudinal plane of symmetry 8 becomes 60 ° ~ 80 ° angle with horizontal surface.In this angular range,, steering swivel becomes the steering tiller 12 of respective angles on connecting, and can improve comfort and connecting shaft and be pivoted service life of structure.
In the present embodiment, said cavity is located on the steering swivel below with the wheel hub point of connection.Design makes front-wheel rocking arm and rocking bar and the steering tiller that will be located on the steering swivel can not interfere like this, and reduces the center of vehicle.
Combine accompanying drawing 4 again; Present embodiment is being assembled into into car with this mechanism with other parts in use; Also to load onto a steering tiller 12 on the steering swivel 1 of this mechanism; Rotate steering tiller 12 and drive steering swivels 1 and wheel hub 3 relative vehicle frame 11 left-right rotation, and connecting shaft 9 to be connected on the vehicle frame 11 through front-wheel rocking arm 10 be that relative vehicle frame 11 is static, both are that the cavity 5 on the steering swivel rotates relative to connecting shaft 9; Connecting shaft 9 runs into prosodetic plane 6,7 greatest limits that arrive left-right rotation of back confined planes on the cavity 5 when turning to a certain extent, and promptly the left and right sides limiting steering limit of motor bike or battery-driven car has arrived.
The beneficial effect of the utility model is that cavity is located on the steering swivel, is directly to pass through the cutting moulding, and working accuracy is high, and the left-right symmetric degree is high, and is spacing even.
The protection domain of the utility model comprises but is not limited only to embodiment, and the real protection scope is main with claims.
