Problems solved by technology

[0004] 1. The front rear drive needs to install a transmission shaft between the engine and the rear axle to transmit power. The installation of the transmission shaft not only increases the weight of the vehicle and affects the overall layout, but more importantly, it has a great impact on the battery box layout of the new energy electric bus. great difficulty;
[0005] 2. The front and rear drive require a larger and longer transmission shaft, which will increase the weight of the vehicle and be detrimental to the speed and cruising range of the electric bus;
[0006] 3. The front and rear drive will cause the floor of the vehicle to rise, which in turn will increase the center of gravity of the car and affect the stability of the car.

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.

Description

technical field [0001] The invention relates to the field of automobile front axles, in particular to an independent suspension type front drive front axle assembly. Background technique [0002] The vehicle front axle assembly in the prior art mainly includes the front axle beam, the real shaft steering knuckle, the kingpin, the steering knuckle arm, the steering trailing arm, the steering tie rod, the hub bearing, the front wheel hub, the brake disc, the air brake, the front Axle locknuts, cotter pins and hub caps. The cross beam of the front axle is connected to the vehicle body through the suspension components such as the steering knuckle and the leaf spring through the kingpin to carry the weight of the vehicle body. The real shaft steering knuckle is connected with the front axle beam through the king pin; the wheel is supported through the connection between the hub bearing, the front axle lock nut and the cotter pin and the front wheel hub; the wheel steering is re...
