Embodiment Construction
[0025] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0026] Such as figure 1 , figure 2 As shown, a new type of shifting actuator for a commercial vehicle transmission in this embodiment includes a shifting actuator and a shifting actuator. The shift actuator includes at least a shift drive mechanism, a shift shaft 4, and a shift selector head 6. The shift selector head 6 and the shift shaft 4 are axially slidably connected by a spline. The way of axial sliding connection of the key is the same as the prior art manual transmission. The gear selection actuator of this embodiment at least includes a gear selection drive mechanism, a gear select...

The invention relates to the field of vehicle transmission, particularly discloses a novel commercial vehicle transmission gear selecting and shifting actuator and a commercial vehicle transmission. Afirst angular displacement sensor connected with a gear shifting shaft and a second angular displacement sensor connected with a gear selecting shaft are used for recognizing gear information at present and target gear information in real time and feeding back the information to a TCU, and the TCU controls a gear selecting motor and a gear shifting motor to work cooperatively to complete automatic gear shifting; the gear selecting and shifting accuracy is improved, gear selecting and shifting inaccuracy caused by nondeterminacy of manual gear selecting and shifting operation is avoided, and damage to a transmission body is avoided; and by means of automatic gear selecting and shifting, the operation convenience and comfort of a driver are greatly increased, and the novel commercial vehicle transmission gear selecting and shifting actuator and the commercial vehicle transmission better meet the market requirement.
Description
Technical field [0001] The invention relates to the field of automobile transmissions, in particular to a new type of shifting actuator for commercial vehicle transmissions and a commercial vehicle transmission. Background technique [0002] Ordinary commercial vehicle transmission selector and shift actuators include gear selector actuator housing, gear selector arm, gear selector shaft, gear selector swing arm, gear shift arm, gear shaft, gear selector head, interlock block, spring , Positioning seat. Its internal structure is that the gear selector arm, gear selector shaft and gear selector swing arm are fixedly connected, and the gear shift arm is fixedly connected with the gear shift shaft. The gear selector head is splined on the gear shift shaft, and the gear selector swing arm is stuck in In the shift selector head groove, the shift selector head can be driven to move axially on the shift shaft. The shift shaft can drive the shift selector head to rotate through the spli...
