As further technological scheme of the present utility model:
In this gear locking device, described return spring places in the guide sleeve, and this guide sleeve is installed on the base plate; The bottom through hole of guide sleeve and position limit pin is slidingly matched and the diameter of this through hole less than the diameter of position limit pin step; The top of guide sleeve installs an end cap, and end cap is provided with through hole and this through hole and position limit pin and is slidingly matched.
In this gear locking device, the top board of described support is provided with the controlling device of adjusting rope length, and controlling device comprises adjutage, adjusting nut, locking nut; Described cable wire is provided with sleeve pipe outward; The endoporus of adjutage is made up of gross porosity, pore, and gross porosity cooperates with the shell clearance of cable wire, and pore cooperates with rope slip; The diameter of pore is less than the external diameter of described sleeve pipe; Adjutage is provided with outside thread, is threaded between adjusting nut and the adjutage and is positioned at the top of top board, and locking nut and adjutage bottom thread are connected and are positioned at the below of top board.
The beneficial effects of the utility model are: this gear locking device can lock the operating rock arm of gear reversing device when vehicle runs up, thereby makes the gear reversing device can't the conversion gear under lock state, has improved the Security of driving; And simple in structure, realize easily.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A-A view of Fig. 1;
Among the figure: 1 cable wire, 2 adjutages, 3 locking nuts, 4 position limit pins, 5 end caps, 6 return springs, 7 supports, 71 top boards, 72 base plates, 73 side plates, 8 shift rocking arms, 9 shift axles, 10 guide sleeves, 11 sleeve pipes, 12 adjusting nuts.
Embodiment
As shown in Figure 1, 2, 3, this this gear locking device mainly comprises support 7, position limit pin 4, cable wire 1.
Support 7 is made up of top board 71, base plate 72, the side plate 73 that is connected between top board and the base plate.Base plate 72 is provided with a through hole, installs guide sleeve 10 in the through hole, and position limit pin 4 passes guide sleeve 10.
Position limit pin 4 is provided with a step, the through hole of guide sleeve 10 bottoms and position limit pin 4 be slidingly matched and the diameter of this through hole less than the diameter of position limit pin step.The top of guide sleeve 10 installs an end cap 5, and end cap 5 is provided with through hole and this through hole and position limit pin 4 and is slidingly matched.Return spring 6 is set between the step of end cap 5 and position limit pin 4.
The bottom of position limit pin 4 is the locking end, and it is corresponding and be positioned at a side of shift rocking arm that this locking end stretches out guide sleeve 10 and shift rocking arm 8.The top of position limit pin 4 is connected between top board 71, base plate 72 and with cable wire 1, and the other end of cable wire 1 passes top board 71 attended operation handles.
The top board 71 of support is provided with the controlling device of adjusting rope length.Controlling device comprises adjutage 2, adjusting nut 12, locking nut 3.The cable wire 1 outer sleeve pipe 11 that is provided with.The endoporus of adjutage 2 is made up of gross porosity, pore, sleeve pipe 11 Spielpassung of gross porosity and cable wire, and pore and cable wire 1 are slidingly matched.The diameter of pore is less than the external diameter of sleeve pipe 11.Adjutage 2 is provided with outside thread, is threaded between adjusting nut 12 and the adjutage 2 and is positioned at the top of top board 71, and locking nut 3 and adjutage 2 bottom thread are connected and are positioned at the below of top board 71.By adjusting the position of adjusting nut 12 on adjutage 2, adjust the length of the cable wire between top board 71 and position limit pin 4 tops, guarantee that the pulling cable wire can directly drive the position limit pin motion, guarantees the reliability of transmission.
