Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings and embodiment, the utility model is described further.
As shown in figure 1, a kind of automatic block selecting top cover of speed changer, including it is vehicle source of the gas (1), decompression venting valve (2), mechanical
On-off valve (3), magnetic valve (4), gearshift guide block (5), shifting cylinder (6), gear shifting pulling head (7), shifting shaft (8), top cover housing
(9), position sensor (10), controller (11), gear arm (12).
Specifically connected mode is：One end access vehicle source of the gas (1), the other end and the mechanical break-make of decompression venting valve (2)
Valve (3) is connected, and mechanical on-off valve (3) is controlled by gear arm (12).
Mechanical on-off valve (3) is connected with magnetic valve (4), and magnetic valve (4) is linked into shifting cylinder (6), shifting cylinder (6)
It is connected with gear shifting pulling head (7) and the position correspondence within the displacement range of gear shifting pulling head (7) is provided with gearshift guide block (5), gearshift is led
Block (5) is connected with position sensor (10) by circuit, and position sensor (10) is connected with controller (11) by circuit, control
Device (11) is connected with magnetic valve (4) by circuit.
Gear shifting pulling head (7) is arranged on shifting shaft (8), and shifting shaft (8) is assemblied in top cover housing (9).
Utility model works principle is：When gear arm (12) is neutral position state, mechanical on-off valve (3), which is in, connects shape
State, vehicle source of the gas (1) is by decompression venting valve (2), and by mechanical on-off valve (3), air pressure is transported to magnetic valve (4), control
Device (11) gives magnetic valve (4) signal and carries out block selecting, and the air pressure of magnetic valve (4) carries out cylinder moving to shifting cylinder (6), so as to
Promoted gear shifting pulling head (7) block selecting in place, after block selecting campaign terminates, gear shifting pulling head (7) correspond to gearshift guide block (5) position and
Gearshift guide block (5) is connected with position sensor (10), and signal is fed back to controller (11) by position sensor (10), and block selecting is completed
Operation.
After the completion of gearshift, mechanical on-off valve (3) is closed, and source of the gas can not be by, and block selecting can not be operated,
Prevent the maloperation after the completion of shifting.
A kind of automatic block selecting top cover of speed changer of the utility model design, this mechanism use Pneumatic shift, are provided with dual
Protection, make operation Portable power saving, reduce gearshift labor intensity, while avoid failure caused by the improper operation such as gear block selecting.
The above embodiments are only preferred embodiment of the present utility model, it is impossible to limit right of the present utility model with this
Scope, therefore, the modification made according to present utility model application the scope of the claims, equivalent variations, improvement etc., still belong to the utility model institute
The scope covered.
