The technical scheme of the utility model is that: the existing brake drums are used, and a plate spring mounting seat belt pipe welding assembly is arranged between the two brake drums. The plate spring mounting seat belt pipe welding assembly is a straight pipe with an axial through hole, and the plate spring mounting seat is symmetrically provided with plate spring mounting seats. The utility model has the advantages that on original electric motor car rear axle assembly basis, will connect the dribbling pipe welding assembly and change into with straight tube both ends boring machine with both ends U template bolt-up and add the back with the change, weld with special mould and pressure equipment with both ends leaf spring mount pad and straight tube pressure equipment back.
Description
Technical Field
The utility model relates to an automobile parts technical field, a lightweight electric motor car rear axle specifically says so.
Background
At present, according to the strong promotion and support of the country on the development of new energy automobiles, the whole automobile factories gradually turn the traditional fuel oil automobiles to electric energy automobiles. Referring to fig. 1, the rear axle of the conventional electric vehicle is formed by connecting a U-shaped plate structure on two sides by a fastening bolt through a connecting disc belt pipe assembly, and the whole axle is heavy in weight and high in production and sale cost. The realization of the whole vehicle weight target of the design and development of new energy vehicles by each whole vehicle factory is seriously influenced.
In order to satisfy each whole car factory to whole car quality global design target requirement, the utility model aims to solve the problem of carrying out lightweight rear axle assembly design on original electric motor car rear axle basis, lightweight rear axle assembly not only can satisfy whole car and bear the requirement to the design of rear axle assembly, can carry out improvement optimization by a wide margin on the reduction requirement of weight on current electric axle assembly basis moreover.
Disclosure of Invention
The technical scheme of the utility model a lightweight electric motor car rear axle is provided.
The utility model discloses a realize like this, use current brake drum, be provided with leaf spring mount pad area pipe welding assembly between two brake drums.
The plate spring mounting seat belt pipe welding assembly is welded with the rear bearing seat, and the rear bearing seat is fixed with the brake drum through a bolt.
The plate spring mounting seat belt pipe welding assembly is a straight pipe with an axial through hole, and the plate spring mounting seat is symmetrically provided with plate spring mounting seats.
The utility model has the advantages that on original electric motor car rear axle assembly basis, will connect the dribbling pipe welding assembly and change into with straight tube both ends boring machine with both ends U template bolt-up and add the back with the change, weld with special mould and pressure equipment with both ends leaf spring mount pad and straight tube pressure equipment back. Simultaneously with the wheel limit biserial tapered roller bearing with nut locking fixed and install locking washer additional and install original ABS system on the wheel hub axle additional, it is more reliable stable to ABS system size connection design and performance.
