The utility model relates to a kind of differential and vehicle, its shell is fixedly connected by welding with main reduction gear, shell is constituted by two half shells and is respectively installed in the axial both sides end surface of main reduction gear. Fixed part for and half shell welding is equipped on the axial both sides end surface of main reduction gear, and positioning part spaced apart from fixed part welding area in radial direction is also equipped, and positioning part supports half shell when welding. The technical scheme will positioning part and welding area be spaced apart, avoid the influence of positioning accuracy by heat distortion generated in welding process, can effectively improve the assembly accuracy and overall performance of differential, ensure the reliable operation of differential.

The application discloses a vertical assembly equipment for a front fork support of a shock absorber, which comprises a shock absorber positioning device, a front fork support positioning device, a tightening device, a spreading component and a top platform; the shock absorber positioning device is used for supporting the shock absorber and making the mounting part of the shock absorber face upward; the front fork support positioning device is used for positioning the front fork support, making the shock absorber connecting part of the front fork support face downward and the side opening of the front fork support face backward; the tightening device comprises a tightening gun and a stop component which are oppositely arranged and are used for aligning and tightening the connecting part; the spreading component is arranged behind the front fork support positioning device, and the spreading part of the spreading component can be inserted into the side opening to spread the shock absorber connecting part; a corresponding device is arranged on the top platform, and the top platform is connected with a lifting driving mechanism and can drive the whole to lift, so that the spread connecting part is sleeved on the shock absorber mounting part. The equipment realizes the automation and accurate control of the assembly process, and improves the assembly quality, efficiency and data traceability.
