Abstract
The present invention discloses a method for measuring steering angles of motorcycle guiding wheels and torque born by a steering locking mechanism with the advantages of simple operation, rapidity, practicality and high precision. A support frame with a cantilever is fixed near a motorcycle, a pen is arranged on the cantilever, and rotary guiding handlebars are respectively rotated towards left or right for respectively drawing two arc lines on the white paper; the rotary centre of the guiding handlebars can be found with a descriptive geometry point sampling method, the centre is respectively connected lines with two end points of the two arc lines, and an included angle of the two connecting lines is a steering angle towards left or right of the guiding handlebars; the size of exerted torque can be calculated by confirming the distance between the rotary centre and a point of application of force. The present invention can simply and rapidly measure an angle between the rotary axis of a guiding column of the motorcycle and the ground. The distance between the point of application of force and the rotary centre can be determined by a simple tool when the torque is measured.
Description
Technical field
The present invention relates to technical field of measurement and test, more particularly, relate to the measuring method of the suffered moment of torsion of the steering angle of a kind of motorcycle direction wheel and steering wheel.
Background technology
Motorcycle is the motor vehicles that are related to personal safety, according to GB 7258-1997 " motor vehicle security of operation technical conditions " regulation, the two-wheeled motor vehicle steering wheel left and corner to the right can not surpass 48 °, motor tricycle can not be above 45 °.
According to GB 17353-1998 " motorcycle and trail bike antitheft device for steering mechanism " regulation, motorcycle must be equipped with the locking anti-theft device, is used for limiting turning to of front-wheel when motorcycle is motionless, plays antitheft effect.Behind the motorcycle direction wheel locking, front-wheel is 20 ° of deflections at least to the left or to the right, and should have that enough intensity is unlikely with the moment of torsion that bears the 200Nm on direction post both direction under the static condition to cause the damage that may jeopardize safe steering mechanism.
According to the requirement of above two standards, must accomplish two: the corner that 1. accurately measures motorcycle direction handle.Must find the rotation center of direction post during the moment of torsion that 2. after measuring locking, can bear exactly.
Axis that the direction post of motorcycle rotates and ground are at an angle, be difficult to come out with simple apparatus measures, in addition, owing to turn to before the motorcycle and the complicacy of suspension system, distance in the time of can't determining to measure moment of torsion with existing ordinary measring tool between the point of application and the rotation center must could realize with special measuring method.These objective factors have limited measure convenient and have realized.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, the measuring method of the suffered moment of torsion of the steering angle of the higher motorcycle direction wheel of a kind of practicality simple to operate, quick, precision and steering lock locking mechanism is provided.
The steering angle of motorcycle direction wheel of the present invention and the measuring method of moment of torsion comprise the steps:
(1) with the minimum point of very heavy jack-up frame of motorcycle, make motorcycle front-wheel liftoff near front-wheel;
(2) on the steering handle clamp device is installed;
(3) blank sheet of paper is fixed on the above-mentioned clamp device;
(4) at the other support of fixing a band cantilever of motorcycle;
(5) on above-mentioned cantilever one-pen is set, nib contacts with paper all the time;
(6) rotation direction is respectively left and turn right, and draws left on above-mentioned blank sheet of paper and two camber lines to the right;
(7) method of getting a little with descriptive geometry finds the steering handle rotation center, and the center is respectively to the two-end-point line of above-mentioned two camber lines thus then, and formed two angles are steering handle and corner to the right left;
(8) determine the distance of the rotation center and the point of application, can calculate the size that applies moment of torsion.
Described clamp device is provided with the V-type groove, and clamping and fixing, described top is provided with fixed bar to two parts handle the motorcycle force direction up and down, and described fixed bar intermediate vertical is provided with application of force lever.
The steering angle of motorcycle direction of the present invention wheel and the measuring method beneficial effect compared with prior art of moment of torsion are: can satisfy the axis that the direction post of simple and convenient measurement motorcycle rotates and the angle on ground; Distance when using simple tool to determine to measure moment of torsion between the point of application and the rotation center.The inventive method is simple, the Yi Ding operation, and steering angle and the rotation center determined with the descriptive geometry method are accurately.
Description of drawings
Fig. 1 is the measurement mechanism synoptic diagram;
Fig. 2 is the clamp device side view.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
By shown in Figure 1, at first, two parts up and down of clamp device 1 are steering handle 2 folders, clamp device 1 has V-type groove 10, the top 11 of clamp device and the lower part 12 of clamp device are clamped motorcycle direction handle 2 and are clamped by manual bolt 13, the top on the top 11 of clamp device has thru-bolt 14, and thru-bolt 14 passes the slotted hole of fixed bar 9, again with nut and fixed bar 9 lockings.In the middle of the fixed bar 9 application of force lever 5 is installed vertically again, is applied moment when being used to measure the lockable mechanism twisting strength.Jack-up frame of motorcycle near the minimum point of front-wheel, make motorcycle front-wheel liftoff, then support 3 is fixed, be adjusted at white board 8 angles of installing on the fixed bar 9, when making motorcycle direction handle 2 left-right rotation white board 8 all the time be installed in cantilever 4 on paintbrush 7 vertical contacts, like this, left and the steering handle that turns right, just on white board, draw left and two camber lines to the right, the method of getting a little with descriptive geometry finds the steering handle rotation center, the center is respectively to the two-end-point line of above-mentioned two camber lines thus then, and formed two angles are steering handle and corner to the right left.
When measuring anti-theft locking apparatus, find the steering handle rotation center with said method earlier, measure that from then on the center is to the distance between the point of application 6 again, this distance value is the moment values of executing with the product of the power that applies.
