Description

Vehicle front axle {Vehicle front axle}

The present invention relates to a front axle for a vehicle, and more particularly, a front for a vehicle having improved wheel alignment by having a different camber angle depending on a vehicle when the spindle is equipped with tires in a spindle mounting portion formed at the end of the front axle. It's about the axle.

Recently, various vehicle manufacturers have been competing with each other to manufacture and sell safe and high-performance vehicles, but no matter how good the vehicle is, if the vehicle is driven by aftercare or inappropriate driving habits, the vehicle will be easily damaged or broken.

The wheel alignment of the vehicle represents an alignment state that correctly maintains the position, direction, and correlation of the wheels mounted on the vehicle, and includes a camber angle, a kingpin inclination angle, a toe-in angle, a caster angle, and the like.

The toe-in has a narrower front than the rear when the front wheel is viewed from above, which prevents the tow-out phenomenon by the camber, makes the wheels coincide with the traveling direction of the vehicle, and prevents the front wheel side slipping. It will play a role.

And the kingpin inclination angle is that the upper part of the kingpin is installed obliquely when the front wheel is seen from the front, reducing the steering wheel handling force and impact during driving and braking, and serves to reduce the steering wheel steering force by reducing the offset amount with the camber.

In addition, the camber angle refers to an oblique state of the front wheel tire (when the front wheel is viewed obliquely upward from the bottom when viewed from the front) when the front wheel is unfolded by a load or the wheel while driving. Is prevented from escaping, and handles are easily operated.

However, the camber angle, caster, kingpin inclination angle, toe-in, etc. play an important role as described above, but the wheel alignment is measured in a state in which it cannot be accurately measured (when the camber angle, caster, thrust, and axle does not match). There was a problem that could harm the safe operation by the wrong measurement value.

That is, when the heavy load is loaded on the vehicle, the steering wheel becomes heavy during driving, and the steering wheel restoration state is not normally performed, and even a slight hill road has a problem in that the output drops and the fuel consumption increases.

In addition, the brake braking distance is long and the vehicle body shakes as well as the vehicle moves along the road surface and the shock is not absorbed, resulting in uneven wear of the tire, resulting in a difficult driving safety.

The present invention has been made in order to solve the above problems, the vehicle has improved the wheel alignment by having a different camber angle according to the vehicle when the spindle is equipped with a tire mounted on the spindle mounting portion formed on the end of the front axle The purpose is to provide a front axle.

In order to achieve the above object, a mounting portion is installed in the horizontal direction in front of the vehicle body, both ends of the mounting portion inclined to extend the spindle mounting portion at a predetermined angle in an upward direction, the spindle mounting portion is provided with a tire Combine the spindle, the inclination angle of the spindle mounting portion is formed in the inclination of 3 to 9 ° counterclockwise relative to the horizontal plane, the inclination angle of the coupling hole formed in the spindle mounting portion is 3 to 9 in the counterclockwise direction relative to the vertical plane In the front axle for vehicles formed at an inclination, the tire has a predetermined inclination with the road surface to form a vertical angle, the vertical angle is formed to be inclined at 1 ~ 5 ° in the case of 1.3t ~ 4.5t truck or small bus , 4.5t or more trucks or large buses are characterized by being inclined at 0.6 ~ 1.5 °.

According to the present invention, the wheel alignment can be improved by having different camber angles depending on the vehicle when the spindle is provided with the tire in the spindle mounting portion formed at the end of the front axle.

Hereinafter, the configuration of the present invention with reference to the accompanying drawings, Figure 1 is a perspective view showing a vehicle front axle according to the present invention, Figures 2 and 3 is a front view showing the mounting state of the vehicle front axle according to the present invention. 4 is a partially enlarged view showing a road surface and a contact state before and after a vehicle front axle according to the present invention.

The vehicle front axle 10 of the present invention is a mounting portion 100 is installed in the horizontal direction in front of the vehicle, and the spindle mounting portion 200 inclined at a predetermined angle in the upward direction at both ends of the mounting portion 100 ) And a spindle 300 coupled to the spindle mounting unit 200 and provided with a tire 500.

That is, the spindle mounting part 200 is integrally formed with a predetermined inclination on both sides of the mounting part 100 formed with a predetermined length, and the spindle mounting part 200 includes a spindle 300 having a tire 500. ) Is mounted.

Here, the size and length of the vehicle front axle 10 may be formed differently according to the size and use of the vehicle.

The mounting portion 100 has a predetermined thickness and is formed in the shape of a cross-sectional shape "H", the mounting portion coupling hole 12 for coupling with other components are formed on both sides.

The spindle mounting portion 200 extending at both ends of the mounting portion 100 has a horizontal plane and a predetermined inclination angle α, wherein the inclination angle α formed on the spindle mounting portion 200 is horizontal and three. An example formed with an inclination of ˜9 ° will be described.

At this time, the inclination angle (α) formed in the spindle mounting portion 200 corresponds to the camber angle to prevent the front wheel from spreading under the load, or to prevent the wheel from being pulled out while driving, and to facilitate the handle operation.

That is, while adjusting the inclination angle formed in the spindle mounting portion 200 to 3 to 9 °, the tire vertical angle (camber angle) λ is formed at 1 to 5 ° or 0.6 to 1.5 ° depending on the vehicle, thereby allowing a tolerance (stopping). In the case of driving), the camber angle λ is reduced according to the speed, so that the bound, slip, brake braking, fuel efficiency, steering wheel operation, tire wear, and vibration phenomenon can be improved.

To further explain this, the vertical angle (λ) is 1.3 to 4.5 ton in the case of a truck or a small bus, because the tire (500) size (height) is small, the camber angle is formed to 1 ~ 5 °, 4.5 In the case of trucks or large buses t or more because the size of the tire 500 is large, the camber angle is formed to be inclined at 0.6 ~ 1.5 °.

The coupling hole 220 formed in the middle of the end of the spindle mounting portion 200 and coupled to the spindle 300 is formed with a predetermined inclination angle β, where the coupling hole is formed on the inner circumferential surface of the spindle mounting portion 200. An inclination angle β of 220 is formed with a vertical and inclined angle of 3 to 9 °.

That is, the conventional coupling hole 220 to which the spindle 300 is coupled is vertically formed, the spindle 300 is mounted, there is a problem that the connection part is bent or severely damaged during driving, but the coupling hole 220 of the present invention. ) Can solve the above problems by forming a predetermined inclination angle (beta) 3 ~ 9 °.

The inclination angle α of the spindle mounting unit 200 and the inclination angle β of the coupling hole 220 may vary depending on the vehicle or application.
