Description

Integral front axle and vehicle with same

Technical Field

The utility model relates to an automobile structure field, in particular to integral front axle and have its vehicle.

Background

The first hard off-road vehicle model is released to date, the appearance, the interior decoration, the four-wheel drive technology and the power system of the hard off-road vehicle are greatly improved, but the integral front axle system serving as the chassis core is not essentially improved.

Over the last 25 years, the sales of global hard off-road vehicles have exceeded 3 million, and consumer demand for customization and modification of such vehicle models has increased. Host plants, refinish shops have become the most popular way of customizing the vehicle body by increasing tire size, replacing or enhancing suspension systems, increasing trafficability, and making the overall appearance of the vehicle more attractive. However, the rise of the vehicle chassis brings the following problems that the driving and control experience of the vehicle is obviously affected, and the safety of personnel on the vehicle is seriously threatened:

1. after the vehicle chassis is lifted, the conventional included angle between the front transmission shaft and the front axle bag is increased due to the change of the mounting position of the integral front axle, so that the U-shaped joint of the transmission shaft vibrates, the U-shaped joint and the sealing piece are damaged, and the probability of abnormal damage of the transmission shaft is greatly increased; at the same time, significant chassis resonances occur during vehicle operation due to distortion of these components;

2. after a vehicle chassis is lifted, the caster angles of the main pins of the claw on two sides of the front axle are simultaneously reduced due to the change of the installation position of the integral front axle, so that when the vehicle runs in a straight line, the shimmy of the front wheel can occur, the steering wheel swings irregularly, the automatic aligning capability of the steering rear direction is weakened, a driver loses road feel, and the vehicle can be controlled without confidence even when the vehicle runs on a conventional road surface;

3. the increase or abrasion of tires, the left-right unbalance of a suspension system and other factors comprehensively cause the running deviation of the vehicle, even the left and right deviation; although the driving deviation can be fundamentally solved by independently and properly adjusting the caster angle of the kingpin of the cleat on one side, at present, the caster angle of the kingpin cannot be independently adjusted because all integral front axles are welded and fixed on the axle tube before leaving a factory.

4. In order to alleviate the symptoms of vehicle deviation described in 3 above, technicians often adjust the wheelbase by changing the length of the chassis control arm. However, the deviation problem cannot be fundamentally solved in the mode, and the vehicle cannot be twisted when passing a curve because the vehicle is not in a regular rectangle when leaving a factory because the vehicle is composed of different wheelbases on two sides; in the driving process, tires on two sides do snake-shaped movement due to the fact that wheel bases are inconsistent, and a driver feels visually that the chassis is loosened and scattered.

The fundamental reason why these problems cannot be solved is the constructional deficiency common to all the monolithic front axles currently on the market: the caster angles of the main pins on both sides of the vehicle and the included angles between the claw and the transmission shaft cannot be independently adjusted. Consumers can only bear various vehicle control problems and major potential safety hazards brought by the consumers; the main engine plant, the refit plant and the refit shop can only spend a great deal of labor and time cost to continuously debug the vehicle, but the effect is little, and the satisfaction degree of customers is low.
