Abstract
The utility model relates to a rear axle, in particular to a rear axle of electric driving vehicle. the utility model is characterized in that: a flange disc is arranged on the housing, a connection disc is arranged on the motor, the flange disc is connected tightly with the connection disc, so that the motor and the housing are connected fixedly to form a whole and the rotating shaft of the motor is vertical with the axial direction of the housing each other, a bevel gear is arranged on the rotating shaft of the motor, the bevel gear is connected with an external gear. As the rotating shaft of the motor is vertical with the axial direction of the housing each other, the rear axle can be directly driven by the bevel gear on the rotating shaft of the motor, thereby omitting intermediate gear so as to simplify the structure greatly; as the housing is molded integrally, the housing has outstanding sealing performance and convenient maintenance; as the pin shaft hole is perforated through entire , the pin shaft is easy to be removed from the exterior, and furthermore the shaft roller is removed, so that the assembly and disassembly of the rear axle are very convenient.
Description
Technical field
Back axle is power transmission essential dedicated transmission when arriving back wheels of vehicle.The utility model relates to a kind of back axle, particularly a kind of battery-driven car back axle.
Background technology
The battery-driven car back axle comprises back axle and electrical motor.Existing battery-driven car back axle, the output shaft of its shaft of motor and back axle is parallel, electrical motor must pass through one or several intermediate gears, could be to back axle power transmission, the existence of intermediate gear makes the device structure complexity, inconvenience is installed, maintenance difficult; In addition, the housing of existing battery-driven car back axle is to be formed by two or more detail assemblys, this modular rear axle housing body, and sealing property is not good enough, and Assembly ﹠Disassembly is all very difficult; At last, the beaming roller of existing battery-driven car back axle is to be fixed on the support by a pin, because pin is embedded in the support fully, institute is so that beaming roller is difficult to dismounting.
Summary of the invention
The purpose of this utility model is the defective that to have battery-driven car back axle complex structure now in order overcoming, inconvenience, maintenance difficult to be installed, and the output shaft of inventing a kind of shaft of motor and back axle is vertical and axle casing is the battery-driven car back axle of integral type.
The purpose of this utility model realizes as follows: described battery-driven car back axle, form by back axle, electrical motor and axletree, back axle comprises housing, support, external gear, gear cluster, two bearings about axially being installed with of housing, support and external gear are fixed in one, and then are located in the housing; Be provided with a beaming roller in the support, gear cluster also is located in the support, and gear cluster comprises four gears, and wherein two are connected with beaming roller, two other gear is connected with axletree by bearing, it is characterized in that: be installed with flange on the described housing, electrical motor is provided with terminal pad, and flange and terminal pad connect airtight, make electrical motor and housing be fixed in one, make the axially orthogonal of shaft of motor and housing, motor rotary shaft is provided with crowngear, and crowngear is connected with external gear.
Described housing is integrated.
Be provided with packing seal between described flange and the terminal pad.
Have pin shaft hole on the described support, this pin shaft hole is to connect entire bracket, is provided with bearing pin in the pin shaft hole, and bearing pin is fixed in beaming roller on the support.
Good effect of the present utility model is as follows: because shaft of motor and housing is axially orthogonal, so can directly drive back axle by the crowngear on the motor rotary shaft, saved intermediate gear, simplified the structure greatly; Because housing is integrated, institute is so that the housing seal superior performance is easy to maintenance; Because pin shaft hole is to connect entire bracket, lower roller is further unloading again so that unload from the outside with bearing pin in institute, makes the Assembly ﹠Disassembly of back axle all very convenient.
