Abstract
The utility model relates to an electro-tricycle, in particular to a rear axle of the electro-tricycle. The rear axle comprises a rear axle tank body; a power shaft of a motor and a differential assembly are arranged in the rear axle tank body; the power shaft is provided with a power gear; the differential assembly is provided with a large gear ring; the rear axle is characterized in that: a gap bridge axle is arranged in the rear axle tank body between the power shaft and the differential assembly; the gap bridge axle is provided with a gap bridge gear which is provided with a gear wheel and a pinion; the gear wheel is meshed with a gear of the power shaft; the pinion is meshed with the large gear ring; and therefore, the rear axle of the electro-tricycle has the advantages of protecting the motor, along with strong power.
Description
Technical field
The utility model relates to electro-tricycle, particularly relates to a kind of electric tricycle rearmost axle.
Background technology
Electric tricycle rearmost axle be motor is installed, with the transmission of power of motor to the parts on the rear axle, it has the back axle casing, on the back axle casing motor is installed, the dynamical axis of motor is in casing; In the prior art; A power gear is installed on the dynamical axis of motor; The bull gear of this power gear engagement differential assembly; Power gear has just directly been given differential assembly with transmission of power like this, and such electro-tricycle has can not slow down, cause its under power sometimes, also can influence the service life of motor.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned shortcoming, provides a kind of power more by force, more can protect the electric tricycle rearmost axle of motor.
The technical scheme of the utility model is achieved in that a kind of electric tricycle rearmost axle; Comprise the back axle casing, have the dynamical axis and the differential assembly of motor in the back axle casing, have power gear on the dynamical axis; Differential assembly has bull gear; It is characterized in that: a gap bridge wheel shaft also is installed on the back axle casing between described dynamical axis and the differential assembly, on the gap bridge wheel shaft carrier gear is installed, carrier gear has big gear wheel and miniature gears; Big gear wheel engagement dynamical axis gear, the pinion bull gear.
Say that further described gap bridge wheel shaft one end is installed on the gap bridge hubcap, middle in the back axle casing of the other end.
On the described back axle casing planetary wheel shell is installed; Described planetary wheel shell is meant that the output shaft of motor connects the housing of dynamical axis through the planet intermediate gear; Described planetary wheel shell the inside has transferring elements, and described transferring elements comprises output shaft, planet intermediate gear, dynamical axis etc.
Perhaps, described gap bridge wheel shaft two ends are installed in respectively on two gap bridge hubcaps, two gap bridge hubcap opposites in the back axle casing.
The beneficial effect of the utility model is: such electric tricycle rearmost axle has simple in structure, power more by force, more can protect more advantage of reasonable of motor, transmitting ratio.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the local structure scheme drawing of the idler shaft portion of Fig. 1.
Wherein: 1, the output shaft 13 of back axle casing 2, dynamical axis 3, differential assembly 4, power gear 5, bull gear 6, gap bridge wheel shaft 7, carrier gear 8, big gear wheel 9, miniature gears 10, gap bridge hubcap 11, planetary wheel shell 12, motor, planet intermediate gear.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of electric tricycle rearmost axle comprises back axle casing 1; The dynamical axis 2 and differential assembly 3 that have motor in the back axle casing 1; Have power gear 4 on the dynamical axis 2, differential assembly 3 has bull gear 5, it is characterized in that: a gap bridge wheel shaft 6 also is installed on the back axle casing 1 between described dynamical axis 2 and the differential assembly 3; Carrier gear 7 is installed on the gap bridge wheel shaft 6; Carrier gear 7 has big gear wheel 8 and miniature gears 9, big gear wheel 8 engagement power gear 4, miniature gears 9 engagement bull gears 8.
Described carrier gear is that two gears are arranged on the axle.
Say that further described gap bridge wheel shaft 6 one ends are installed on the gap bridge hubcap 10, middle in the back axle casing of the other end; Be that described gap bridge wheel shaft 6 is semiaxis; This is because receive the restriction of back axle casing 1 size, and is compact with semiaxis, also meets the size of carrier gear 7.
Perhaps, described gap bridge wheel shaft two ends are installed in respectively on two gap bridge hubcaps, two gap bridge hubcap opposites in the back axle casing, and the wheel shaft of promptly passing a bridge is an axis, has more firm advantage like this.
On the described back axle casing 1 planetary wheel shell 11 is installed; The output shaft 12 that described planetary wheel shell 11 is meant motor connects the body skin of dynamical axiss 2 through planet intermediate gear 13, and certain described planetary wheel shell 11 the insides have transferring elements such as the output shaft 12, planet intermediate gear 13, dynamical axis 2 of motor.
Like this, during work, power transmits a big gear wheel through power gear, motion that the large gear turn the small gear, and miniature gears drives bull gear, through slowing down, can realize the purpose of this real utility model.
