Abstract
The invention discloses an independently suspended front drive front axle assembly. The front end of each transmission semi-axle is provided with a front drive shaft assembly. A sleeve type steering knuckle is installed at the front end of each front drive shaft assembly in the radial direction, and a transmission spline shaft is arranged at the front end of each front drive shaft assembly in the axial direction. Each transmission spline shaft is engaged with a spline sleeve on the inner side of a left front wheel hub and a spline sleeve on the inner side of a right front wheel hub. The front end of each transmission spline shaft is provided with a screw rod which is matched with a locking nut fastened to one end of the corresponding spline sleeve. Each spline sleeve is sleeved with a bearing pedestal, and each bearing pedestal is arranged at the front end of the corresponding steering knuckle. Conical roller bearings are arranged between the bearing pedestals and the spline sleeves in pairs. A brake disc is fixed to the inner side of the front wheel hub. Brake assemblies in friction joint with the brake disc are symmetrically arranged on the brake disc front and back in the transverse direction. The brake assemblies are fixed to the two sides of a flange plate. Brakes are hydraulic drive brakes. As for a front drive mechanism, an original transmission shaft structure for connecting an engine with a rear wheel is omitted, the height of a chassis of a large/medium-sized passenger vehicle can be reduced properly, meanwhile, the weight of the passenger vehicle is reduced, and running stability is improved advantageously.
