Description

Battery car driving rear shaft

Technical Field

The utility model belongs to the technical field of the vehicle transmission, a storage battery car drive rear axle is related to.

Background

The storage battery car is a motor vehicle driven by a storage battery to provide electric energy and then a motor, the conventional storage battery car generally adopts a mode that a rear wheel drives a front wheel to steer, so that a rear shaft of the conventional storage battery car is used for driving and also plays a role in supporting the whole weight of the storage battery car frame, a wheel disc and a brake disc are usually fixedly connected to a driving rear shaft, and in the current mounting structure, due to the fact that the driving mode of a vehicle driver is violent, the disc surface is prone to tilting, the driving and braking of the storage battery car are influenced, and abnormal sound is sometimes generated.

Disclosure of Invention

The utility model aims at providing a battery car drive rear axle that overall structure is firmer to the above-mentioned problem that exists among the prior art.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a storage battery car drive rear axle, includes the drive shaft and links firmly rim plate and brake disc at the drive shaft both ends, a serial communication port, the terminal surface of rim plate has seted up the circular shape spacing groove of round and is provided with spacing step in the spacing groove, and one side of rim plate is provided with the driving disc and fastens through hexagon screw and rim plate, and wherein the head of hexagon screw carries out the circular shape thickening of round and clearance fit in the spacing groove, and the head bottom surface of fastening back hexagon screw offsets with spacing step and leans on, the brake disc link firmly in the drive shaft through the ring flange, the ring flange is located in the drive shaft through the chuck card, the even double-screw bolt that has linked firmly of terminal surface circumference of ring flange, the double-screw bolt passes through the external screw thread and the ring flange cooperation is fixed and set up at.

The principle of the driving rear axle of the battery car is as follows: the motor drives the wheel disc to rotate through the chain, the wheel disc transmits rotating power to the driving shaft through the transmission disc fixedly connected to the end face of the wheel disc, the middle part of the driving shaft is fixedly connected with the steel ring so as to realize the operation of the rear wheel, the technical effect of the utility model is that the contact area of the wheel disc is increased by matching and fastening the wheel disc and the end face of the transmission disc, the wheel disc is not easy to deform, further, the head part of the conventional hexagon nut is thickened and is in clearance fit with the limiting groove on the wheel disc, the coaxiality of the wheel disc and the transmission disc is higher after fastening, the transmission efficiency is higher, and the design of the fixed structure can effectively prevent the wheel disc from inclining, the brake disc of the driving rear shaft is fixed on the driving shaft through the flange disc, the installation and the replacement of the brake disc are more convenient, the stress point of the brake disc can radially, and the change of the inclination is smaller during braking, so that the battery car is braked more smoothly.

In the battery car driving rear axle, the wheel disc is clamped at the end part of the driving shaft and is fixed by screwing the stop ring, and the outer ring of the stop ring is fastened with a circle of hoop.

In the battery car driving rear shaft, the transmission disc and the driving shaft are in spline fit to realize transmission.

Compared with the prior art, this storage battery car drive rear axle is fixed in the rim plate and brake disc respectively in the drive shaft through driving disc and flange dish, makes its lifting surface's diameter bigger, has overall structure firmer quotation wayward, and the storage battery car advantage that the automobile body is more stable when going and braking.
