Fig. 4 is a drive mechanism schematic representation of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-4:
The electric vehicle retarder, comprise front cover 11, rear end cover 12 formed hollow box bodies 10, the driving disc 111 of casing 10 front covers 11 is provided with the axis hole that can allow main shaft 20 be connected with motor, the driving gear 21 that is connected with main shaft 20 is connected with driven wheel of differential 40 by train of reduction gears 30, outer wall at casing 10 is provided with the tank filler sleeve 13 that is communicated with casing 10 hollow portions, oil drainage hole 14 and exhaust port 15, the inwall of described casing 10 is provided with groove 16, be provided with the magnet 161 of adsorbable iron filings in the groove 16, be provided with the time speed sensors 171 of test speed at driven disc 17 places of casing 10, driven wheel of differential 40 in the described driven disc 17 is fixedlyed connected with differential mechanism, the iron filings that magnet 161 adsorbable retarders produce in operation prevent that these iron filings from exerting an influence to the running of retarder.
Above-mentioned differential mechanism is: differential casing 50 is fixedlyed connected with driven wheel of differential 40, be symmetrically arranged with differential gear 51 and planetary pinion 52 respectively in the inside of differential casing 50, described differential gear 51 connects respectively at output shaft, described planetary pinion 52 interconnects by planet pin 53, described differential gear 51 is meshing with each other with the teeth groove of planetary pinion 52, automobile is when straight-line travelling, differential casing 50 drives planet pin 53 rotations, thereby driving planetary pinion 52 revolves round the sun around the differential gear axis, planetary pinion 52 around the revolution of differential gear axis with differential gear 51 clampings, drive differential gear 51 outputting powers, differential gear 51 drives by planetary pinion 52 speed of both sides output is equated; During turning, inboard radius of turn is little, running resistance increases, rotation has taken place in planetary pinion 52 on the basis of original revolution, make the inboard wheel rotating speed be lower than differential casing 50 rotating speeds, and the opposite side vehicle wheel rotational speed is higher than the rotating speed of differential casing 50, and this makes the rotating speed of inboard differential gear 51 outputs little, big convenient turning of the rotating speed of differential gear 51 outputs in the outside.
The above-mentioned both sides at driving gear 22, train of reduction gears 30 and dynamic bevel gear 40 are respectively arranged with ball bearing 60.
The above-mentioned driving disc 111 and the inwall of driven disc 17 are provided with the oil sealing 70 of anti-leakage of oil.
The rear end cover 12 of above-mentioned driving disc 111 is provided with the axis hole that can link to each other with oil pump, and this axis hole links to each other with oil pump by it when retarder need be installed oil pump not needing to drive under the situation of oil pump and can covering with cover plate 121 again.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection domain of the present utility model according to this; so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
