Embodiment Construction

[0029] figure 1 A schematic structural diagram of a vehicle synchronizer assembly according to an embodiment of the present invention is shown. Such as figure 1 As shown, the vehicle synchronizer assembly generally includes a gear hub 6 , a gear sleeve 7 , a slider 5 , a synchronization ring 2 , engaging teeth, a spring 3 and a steel ball 4 . The gear hub 6 is sleeved outside the working shaft of the vehicle, and the gear sleeve 7 is sleeved outside the gear hub 6 . The gear sleeve 7 is driven by the shift fork to move axially, passes through the synchronous ring 2, and meshes with the gear gear 11 to realize shifting and transmitting torque. The synchronous ring 2 synchronizes the speed gear 11 and the gear sleeve 7 with different rotating speeds quickly before engaging the teeth through the conical surface friction pair. In order to solve the technical problem of incomplete meshing after shifting due to wear of the locking angle between the tooth sleeve 7 and the engaging...

Abstract

The invention provides a vehicle synchronizer assembly and a vehicle. The vehicle synchronizer assembly includes a gear hub sleeved outside the working shaft of the vehicle, a gear sleeve sleeved outside the gear hub, and at least A hydraulic rod device, each hydraulic rod device includes a hydraulic rod and a drive mechanism for driving the hydraulic rod to reciprocate between the working state of being stuck in the shift fork groove and the non-working state of exiting the shift fork groove; The mechanism is configured as follows: when the rotating speed of the working shaft is different from the rotating speed of the gear gear to be engaged by the gear sleeve, the hydraulic rod is driven to make it in the working state to prevent the gear sleeve from engaging with the gear, and when the rotating speed of the working shaft is different from the gear gear When the rotational speeds of the gears are the same, the hydraulic rod is driven to make it in a non-working state, so that the gear sleeve is engaged with the gear. The solution of the present invention solves the technical problem of incomplete meshing after shifting due to wear of the locking angles of the tooth sleeve and the engaging teeth.

Description

technical field [0001] The invention relates to the technical field of vehicle transmissions, in particular to a vehicle synchronizer assembly and a vehicle. Background technique [0002] As an important part of automobile products, the transmission can ensure the best working condition of the engine and realize the reverse gear of the automobile. Synchronizers are key components for gear shifting in automotive transmissions, including sub-components such as gear hubs, gear sleeves, sliders, synchronization rings, and engaging teeth. The gear sleeve is driven by the shift fork to move axially, passes through the synchronous ring, and meshes with the engaging teeth to realize shifting and transmission of torque. The synchronous ring synchronizes the gears with different speeds and the tooth sleeves quickly before engaging the teeth through the conical surface friction pair. [0003] The vehicle gear shift of MT / AMT / DCT is realized through the clutch. The clutch is separate...
