The beach buggy steering unit that reverses gear
Technical field
The utility model relates to the self-propelled vehicle steering unit that reverses gear, especially a kind of steering unit that reverses gear of beach buggy.
Background technology
At present, reverse gear the external beach buggy reverse gearing device by hand pull down the retaining steering unit finish gearshift, this steering unit that reverses gear is by handle, adapter plate, hinge-rod, connecting lever and drag-line constitutes, one end of handle by passing adapter plate rotational pin and an end of hinge-rod link, the other end of hinge-rod links by an end that connects lever and drag-line, spacing hole and reverse gearing device that the other end of drag-line passes on the adapter plate flanging link, because the angle that handle rotates during the reverse gearing device gearshift is bigger, drag-line will produce interference with the inwall and the aperture profile in adapter plate flanging upper limit hole in the sway process, drag-line can not be smooth and easy mobile in this spacing hole, sensation effort when causing spanner handle, sometimes even influence normally carrying out of gear shift operation.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of rapid operation is provided, and can guarantee drag-line smooth and easy mobile beach buggy in adapter plate spacing hole steering unit that reverses gear.
For this reason, the beach buggy described in the utility model steering unit that reverses gear, comprise handle, adapter plate, hinge-rod, connection lever and drag-line, one end of handle by passing adapter plate rotational pin and an end of hinge-rod link, the other end of hinge-rod links by an end that connects lever and drag-line, the other end of drag-line passes the spacing hole on the adapter plate flanging, and adapter plate is provided with roller, and this roller is positioned at a side of drag-line and carries out spacing to it.
Above-mentioned drag-line connects journal stirrup by U-shaped and links with an end that is connected lever, and adapter plate is provided with positioning plate, and positioning plate is provided with two spacing block sets and matches with locating dowel pin on the hinge-rod.
It carries out spacing owing to the side at drag-line is provided with pair of rollers in the utility model, when drag-line is mobile under the drive of connection lever, because the effect of roller, make and to be similar to the direction identical in the spacing hole of drag-line on the adapter plate flanging and to move with the spacing hole axial line, can not interfere with the inwall and the aperture profile of spacing hole, and be mainly friction of rolling between drag-line and the roller, resistance is very little, thereby can guarantee that the smooth and easy of drag-line moves.
The beneficial effects of the utility model are: rapid operation, comfortable, and make the gear shift operation of reverse gearing device can smooth and easy carrying out, reliable operation, and prolonged service life of drag-line.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As Fig. 1, shown in Figure 2, the beach buggy described in the utility model steering unit that reverses gear, by handle 1, adapter plate 2, hinge-rod 3, connect lever 4, drag-line 5, roller 6, connect journal stirrup 7, positioning plate 8 and rotational pin 9 are formed, handle 1 is a ball handle, the rotational pin 9 of one end of handle 1 by passing adapter plate 2 links with an end of hinge-rod 3, the other end of hinge-rod 3 links by an end that connects lever 4 and drag-line 5, the other end of drag-line 5 passes the 2a of spacing hole on adapter plate 2 flangings, adapter plate 2 is provided with roller 6, and this roller 6 is positioned at a side of drag-line 5 and carries out spacing to it.
Can find out from Fig. 1, Fig. 2: drag-line 5 connects journal stirrup 7 by U-shaped and links with an end that is connected lever 4, adapter plate 2 is provided with positioning plate 8, positioning plate 8 is provided with two spacing block set 8a and 8b and matches with locating dowel pin 3a on the hinge-rod 3, and two spacing block set 8a and 8b be the starting point and the final position of corresponding hinge-rod 3 rotational travel respectively.
Adapter plate 2 is fixed on the vehicle frame in the utility model, the end that drag-line 5 stretches out adapter plate 2 flanging upper limit hole 2a links by the gearshift axle of transmission component and reverse gearing device, during gearshift, pull handle 1 with hand, handle 1 drives hinge-rod 3 untie-sell 9 that rotates and rotates, by connecting lever 4 and connecting journal stirrup 7 pulling drag-lines 5, after gearshift put in place, spacing block set 8a or 8b on the limited plate 8 of the locating dowel pin 3a on the hinge-rod 3 carried out spacing hinge-rod 3 again.
The steering unit that the utility model also can be used as the beach buggy diff uses.
