Abstract
The utility model discloses an independent rear suspension transmission device of an electric vehicle. The independent rear suspension transmission device comprises a chassis, a motor and a gearbox, wherein the motor and the gearbox are fixedly connected onto the chassis; the two sides of the chassis are fixedly connected to two corresponding rear rocker arms; a brake and a ball cage rear axle hub flange are fixedly connected onto each rear rocker arm; inner ball cages are connected to two side output ends of the gearbox; outer ball cages are connected onto the ball cage rear axle hub flange; the inner ball cages are connected with the outer ball cages through a ball cage connecting rod; and spring shock absorbers are connected between the rear rocker arms and the chassis. The independent rear suspension transmission device of the electric vehicle has the characteristics of simple and compact structure and good driving and riding comfortableness.
Description
Technical field
The independent back that the utility model relates to a kind of battery-driven car hangs transmission device, and the independent back that relates in particular to a kind of electric four-wheel vehicle hangs transmission device.
Background technology
Current domestic electric four-wheel vehicle generally all adopts beam rear axle to add that steel spring or rocking arm add the structure design of spring damper, can't guarantee comfort level is had the driver's of requirement demand.Add two trailing wheels since the constraint of beam rear axle can't reach two rear wheel independent suspensions the time to ground-surface adaptation, so restricted beam rear axle structure vehicle to rugged ground-surface carrying capacity, thereby limited the scope of using.
Summary of the invention
The purpose of this utility model provides a kind of simple and compact for structure and independent back suspension of the battery-driven car raising ride comfort driving system.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of independent back of battery-driven car hangs driving device, comprise the chassis, motor and change speed gear box, motor and change speed gear box are fixedly connected on the chassis, the both sides on described chassis are fixedly connected with two corresponding rear arms, be fixedly connected with drg and ball cage back axle wheelboss flange on the every rear arm, all be connected with internal spherical cage on the both sides mouth of change speed gear box, be connected with the ectosphere cage on the ball cage back axle wheelboss flange, link to each other by ball cage connecting rod between internal spherical cage and the ectosphere cage, be connected with spring damper between rear arm and the chassis.
Described chassis is provided with positioning seat, back positioning seat and motor positioning seat; Change speed gear box is fixedly connected on the chassis by last positioning seat, back positioning seat and the lining that suspends, and motor is fixedly connected on the chassis by the motor positioning seat and the lining that suspends.
Be set with brake hubs on the described drg.
Structure of the present utility model adopts the independent left and right rear arm, and spring shock absorption tube and ball cage back axle wheelboss flange have been realized independently knee-action of two trailing wheels; By adopting ball cage universal-joint that the output of change speed gear box is transferred to the wheelboss flange of both sides respectively, realize the rotation of wheel.Drg is connected on the rear arm of the left and right sides, and brake hubs is linked on the ball cage back axle wheelboss flange, thereby realizes the effective braking to vehicle.This kind structure helps the output of power actv., has improved the ride comfort of vehicle simultaneously, and to rugged ground-surface carrying capacity.
