Description
Technical field
The utility model relates to a kind of cross-country motorcycle seat cushion regulating mechanism, particularly a kind of connecting rod mechanism of scalable cross-country motorcycle bench height.
Background technology
Since motor bike comes out, bring great convenience for customer's traffic life, but along with expanding economy, the continuous change of consumer spending idea, to the effect of motor bike with require to have had again new understanding, the customer is except as the walking-replacing tool, also require to have good tractive performance and cross-country effect, therefore cross-country motorcycle more and more is subjected to liking of ordinary consumer, and along with the popularization of motor bike race, increasing ordinary consumer begins to participate in the motor bike cross-country movement.
At present normal domestic motorcycle seat cushion height between the 750-800 millimeter, is many with the 760-780 millimeter wherein generally, and the bench height of cross-country motorcycle is generally more than 850 millimeters, and the cross-country motorcycle of big discharge capacity is more than 900 millimeters.Because motorcycle seat cushion and cross-country motorcycle seat cushion are fixed on car and drive, just can't regulate bench height after dispatching from the factory, such bench height is requiring aspect height, the technical ability than higher the rider personnel, for the ordinary consumer of different heights, just can't regulate bench height and satisfy the only height that drives of each customer, owing to drive the posture discomfort, drive for a long time and will produce the malaise symptoms of having a pain in the back, even can cause the safety of driving.For this reason, many manufacturers and knowledgeable people have carried out R and D, and product emerges but do not have reasonably so far as yet.
Summary of the invention
In order to overcome the problems referred to above that existing cross-country motorcycle exists, the purpose of this utility model provide a kind of simple and reasonable, the seat cushion height is easy to adjust, the connecting rod mechanism that drives comfortable a kind of scalable cross-country motorcycle bench height.
The technical scheme that its technical matters that solves the utility model adopts, it comprises vehicle frame, back chain stay, rear shock absorber, back chain stay connects to ground, the top of rear shock absorber connects to ground, the below of described back chain stay is hinged with the symmetrical triangular connecting rod, on the camshaft mounting hole of symmetrical triangular connecting rod camshaft is installed, be hinged with the connecting rod of symmetry on the connecting rod mounting hole of camshaft both sides end face respectively, the other end correspondence of the connecting rod of symmetry is hinged on the vehicle frame connecting strap of vehicle frame, and the lower hinge of rear shock absorber is on the symmetrical triangular connecting rod.
The two ends of described camshaft are provided with the eccentric cylinder of symmetry, and the inboard of eccentric cylinder is provided with limited step, is provided with the face of adjusting up and down between two limited steps.
The camshaft mounting hole of described triangular coupling rod is provided with locking slot, and locking slot is provided with lock screw, and the camshaft mounting hole of triangular coupling rod is assemblied on the eccentric cylinder of camshaft.
After adopting said structure, the utility model compared with prior art has following advantage and effect: the one, utilize the eccentric throw of camshaft, regulate the relative position of triangular coupling rod and connecting rod by the angle of rotating cam axle, make the position between rear shock absorber, vehicle frame, the back chain stay produce change at last, thereby changed the angle of back chain stay and Full Vehicle System.Because the structure and the size of back chain stay are fixed, the variation of back chain stay angle can cause the rotation of Full Vehicle System around front wheel spindle, and then causes the lifting or the decline of Full Vehicle System, thereby reaches the purpose of adjusting bench height;
The 2nd, with changing the rear shock absorber of motorcycle angle, improve the traveling comfort of car load by above-mentioned adjusting.
The 3rd, method of adjustment is simple and convenient, and ordinary consumer can carry out, and this helps cross-country motorcycle, and particularly the cross-country motorcycle of big discharge capacity is promoted the use of to ordinary consumer.

The specific embodiment
Fig. 1 is to shown in Figure 5, embodiment for the connecting rod mechanism of a kind of scalable cross-country motorcycle of the utility model bench height, it comprises vehicle frame 7, back chain stay 4, rear shock absorber 5, back chain stay 4 is connected with vehicle frame 7, the top of rear shock absorber 5 is installed on the vehicle frame 7 by shackle plate, the below of described back chain stay 4 is hinged with symmetrical triangular connecting rod 2 by bearing 8, on the camshaft mounting hole 14 of symmetrical triangular connecting rod 2 camshaft 1 is installed, be hinged with the connecting rod 3 of symmetry on the connecting rod mounting hole 13 of camshaft 1 both sides end face respectively by bearing 8, the other end of connecting rod 3 of symmetry is hinged on by bearing 8 correspondences on the vehicle frame connecting strap 6 of vehicle frame 7, the bottom of rear shock absorber 5 by bolted splice on symmetrical triangular connecting rod 2.
The two ends of described camshaft 1 are provided with the eccentric cylinder 12 of symmetry, the inboard of eccentric cylinder 12 is provided with limited step 10, limited step 10 plays positioning action, is provided with between two limited steps 10 and adjusts face 11 up and down, adjusts face 11 up and down and is mainly used in seat cushion rotating cam axle 1 when just regulating.
The camshaft mounting hole 14 of described triangular coupling rod 2 is provided with locking slot, and locking slot is provided with lock screw 9, and the camshaft mounting hole 14 of triangular coupling rod 2 is assemblied on the eccentric cylinder 12 of camshaft 1.
Figure 5 shows that seat cushion is in the contrast scheme drawing of high-order and low level two states, the solid line part is in high-end trim for seat cushion among the figure, and the eccentric cylinder 12 of camshaft 1 is positioned at car the place ahead, adjusts face 11 up and down and be horizontal at this moment; Dotted portion is that seat cushion is in low-end trim among the figure, and the eccentric cylinder 12 of camshaft 1 was positioned at the car rear, adjusted face 11 up and down and be horizontal this moment.The eccentric throw of different camshafts 1, different triangular coupling rods 2 and connecting rod 3 sizes are adjusted under the angle at different camshaft 1, can realize different seat cushion adjustment height.
Fig. 6 to Fig. 9 is the application example of a 300cc/500cc cross-country motorcycle of the utility model new product, wherein the eccentric throw of camshaft 1 is 5 millimeters, the pitch-row of connecting rod 3 is 146 millimeters, the concrete size of triangular coupling rod: the pitch-row between rear shock absorber connecting bore 15 and camshaft mounting hole 14 and the back chain stay connecting bore 16 is followed successively by 82.5 millimeters and 90 millimeters, and back chain stay connecting bore 16 is 62.5 millimeters with the pitch-row of camshaft mounting hole 14.During adjusting, as long as unclamp the lock screw 9 on camshaft 1 fix screw and the triangular coupling rod 2, use spanner adjusting cam axle 1 to the angle that is fit to, the fastening successively again screw that unclamps gets final product, when the rotational angle of camshaft 1 was 180 °, seat cushion can be realized the regulated quantity of 30 millimeters height.
