Embodiment
The utility model comprises: a gear, and the central authorities of this gear establish an axial receiving hole, are made as a ratchet ring at the inwall of receiving hole; And a sheathed bearing, this bearing is positioned at the adjacent side of ratchet ring, and its ratchet ring and bearing are same axle center; An and sheathed ratchet wheel in ratchet ring; This ratchet wheel then cooperates an axletree heart in addition, by the ratchet ring and the ratchet wheel of gear, drives the axletree heart and does unidirectional rotation.
For understanding and approval further can be arranged structure, characteristic and the effect of the utility model, enumerate following preferred embodiment and conjunction with figs. the explanation as after.
See also Fig. 1 to shown in Figure 3, the utility model is the ratchet of (not drawing among the figure) in the driving device for electric vehicle, comprises:
One gear 10 is established an axial receiving hole 11 in these gear 10 central authorities, and is made as a ratchet ring 12 at the inwall of receiving hole 11; An and sheathed bearing 13; This bearing 13 is positioned at ratchet ring 12 adjacent sides, and its ratchet ring 12 is same axle center with bearing 13, and in ratchet ring 12 a sheathed ratchet wheel 14; Can be cooperated with ratchet wheel 14 by the ratchet ring 12 of gear 10, driven gear 10 is made one-way rotation.
Please continue to consult Fig. 1 to Fig. 3, utilize said modules to form the structure of the utility model, bearing 13 is sheathed in the receiving hole 11 of gear 10, and in ratchet ring 12 sheathed this ratchet wheel 14,14 of this ratchet wheels axletree heart 20 of planting in addition.
When starting electric motor car; When relatively drive unit started, the motor of this drive unit rotated power transmission to gear 10, let the ratchet ring 12 in the gear 10 rotate again thereupon; And drive ratchet wheel 14 and then rotates; By gear 10 drive in the ratchet rings 12 sheathed ratchet wheel 14 rotations, and outputting power to the axletree heart 20 rotates, and lets electric vehicle running.
