Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the schematic diagram of the gearshift of background technology.
Fig. 2 is the schematic diagram of the gearshift of the present invention.
Embodiment
Fig. 2 is refer to, the high low gear gearshift of ecp, including a gearbox 1, one are packed in outside gearbox 1
Mounting bracket 8, one be packed in cylinder 9 in mounting bracket 8, a three-way solenoid valve 14, one and switch 13, one power supply 12
With a source of the gas 17.
The gearbox 1 includes output shaft 3, mobile tooth set 4, high gear 5, low-speed gear 2, selector fork axle 7 and changed
Keep off shift fork 6；The mobile tooth set 4 connects output shaft 3 so that mobile tooth set 4 can be rotated with output shaft 3 and mobile tooth set 4 can be relative
Output shaft 3 is moved axially, for example, move tooth set 4 and be connected to output shaft 3 by spline, and mobile tooth set 4 can be along spline slide；Institute
The axis for stating high gear 5 and low-speed gear 2 all coincides with the axis of output shaft 3, high gear 5 and the difference of low-speed gear 2 position
4 both sides are covered in mobile tooth；The energy of selector fork axle 7 gearbox 1 relatively slides axially along itself, selector fork axle 7 and output
Axle 3 is arranged in parallel, and the connection selector fork of selector fork 6 axle 7 and mobile tooth set 4, the movement of selector fork axle 7 can pass through selector fork
6 drive the mobile movement of tooth set 4 to select engagement high gear 5 or low-speed gear 2, such as affixed selector fork in selector fork one end
Axle 7, other end fork-join movement tooth set, so that mobile tooth set can be driven mobile and do not influence to move tooth set rotation.The high speed tooth
Wheel 5, low-speed gear 2 are all duplicate gear.
The cylinder 9 has piston rod and cylinder 9 is separated to two cavitys (the left and right chamber in figure) of formation by piston rod,
Piston rod and selector fork axle 7 are connected and piston rod axis and the axis of selector fork axle 7 are overlapped, and three-way solenoid valve 14 passes through
Two tracheaes 10,11 connect two cavitys of cylinder 9, and three-way solenoid valve 14 also connects source of the gas 17 by tracheae 15；The power supply
