Description

Integrated expansion power vehicle axle tube

Technical Field

The utility model relates to an electric tricycle spare part field especially relates to an integrative shape power car bridge pipe that rises.

Background

The axle refers to the rear driving shaft component of the vehicle power transmission. In the prior art, a vehicle rear axle is mainly composed of two half bridges, and half bridge differential motion can be implemented. It is also a device for supporting the wheels and connecting the rear wheels. At present, the integral punching-welding bridge is used in the market, the main structure of the integral punching-welding bridge is that a middle bridge package is formed by punching, welding and forming and steel pipes welded on two sides, the material cost is high, the working procedure is long, the manufacturing cost is high, the production period is long, the efficiency is low, the labor intensity is high, the operation benefit is poor, in the using process of the axle, the position of a welding line is in the key position of bearing, the continuous impact force of repeated jolting up and down is borne, the impact force is 3-5 times higher than the static compressive strength, even higher than the static compressive strength, the welding line is the weakest position, the welding line is easy to crack to cause oil leakage, the strength is also reduced, because the strength is reduced, the meshing position of a gear on a half shaft and the gear of a gear box deforms up and down along with the axle load, the meshing stress is not stable, the abrasion of two meshing tooth parts is accelerated, the service life of the gear is reduced, significant damage is also caused to the cantilevered half shafts and gear boxes.

In view of the above, an integrated expansion power axle tube has been developed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the defects in the prior art, providing an integrated expansion power car bridge pipe, digging out a steel pipe in the middle of the steel pipe, forming an integral bridge pipe by using the expansion of a mould, having short working procedure, reducing the material consumption and the number of welding blocks and being easy to realize automatic processing; the production period is shortened, the production efficiency is improved, the production cost is greatly reduced, the whole bridge pipe has a good hydrodynamic shape, and the bending resistance and the compressive strength are improved.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: an integrated expansion power vehicle axle tube, which comprises: the bridge pipe, the shaft pipe, the transition pipe, the connecting plate, the reinforcing plate mounting groove, the bridge package, the sewage draining outlet, the reinforcing plate and the flange plate; the middle part of the bridge pipe is provided with a bridge package, the upper end of the bridge package is provided with a flange, the flange is superposed with the center of the bridge package, and the bottom plate of the bridge package is provided with a sewage outlet;

the bridge pipe has the structure that: central siphon one end sets up the transition pipe, the overlook structure of transition pipe is fan-shaped, the front end diameter of transition pipe is less than the rear end diameter, the rear end of transition pipe sets up inside sunken arc surface, the upper and lower surface middle part of transition pipe sets up the reinforcing plate mounting groove, set up the reinforcing plate in the reinforcing plate mounting groove, the front end of transition pipe sets up on the central siphon, the transition pipe on a pair of central siphon sets up in opposite directions, set up convex connecting pipe between a pair of transition pipe, enclose into circular shape bridge package installation cavity between a pair of transition pipe and a pair of connecting pipe, the central siphon, transition pipe and connecting plate integrated into one piece.

The utility model has the advantages that: the utility model discloses a steel pipe is planed out in the middle of the steel pipe, and the die is used for expansion to form an integral bridge pipe, so that the process is short, the material consumption and the number of welding blocks are reduced, and a plurality of tools, equipment and production workers are used; parts are reduced, and automatic processing is easy to realize; production cycle shortens, has improved production efficiency, very big reduction manufacturing cost, and the bridge pipe adopts the structure of integrative shape that rises, does not have the welding seam at main bearing position, has prevented the oil leak, and the bridge pipe wholly has good hydromechanics shape, has improved bending resistance compressive strength, adopts welding triangle-shaped's reinforcing plate, further consolidates and promotes the bending resistance and the compressive strength of bridge pipe, the utility model discloses not only be limited to electric tricycle, new forms of energy passenger, goods and vehicles also can use.
