Description

Front axle and vehicle with adjustable thread tightening

Technical Field

The utility model relates to an automobile structure field, in particular to front axle and vehicle with adjustable thread tightening.

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 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 a vehicle chassis is lifted, the conventional included angle between a front transmission shaft and a front axle bag is increased due to the change of the installation position of a front axle, so that the U-shaped joint of the transmission shaft vibrates, the U-shaped joint and a 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 front axle, so that when the vehicle runs in a straight line, the shimmy of the front wheel can occur, the steering wheel is unstable in swinging, the automatic aligning capability of the steering direction is weakened after the vehicle is steered, 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 driving and adjusting the caster of the kingpin on one side by a proper amount can fundamentally solve the running deviation, the ram horn connected with the kingpin is welded and fixed on the bridge pipe before all front axles leave a factory, so the caster of the kingpin cannot be adjusted independently.

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 problem of deviation cannot be fundamentally solved in the mode, and the vehicle cannot be twisted when passing a curve because the vehicle is not a regular rectangle when leaving a factory and consists 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 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.

As shown in fig. 1 to 4, the adjustable front axle with thread fastening provided by the first embodiment of the present invention includes a bridge package 10, two bridge tubes 20 respectively connected to two sides of the bridge package 10, a cleat 30 and a pressing plate 40 located at one end of the bridge tube 20 far away from the bridge package 10 and used for connecting a kingpin (not shown), wherein at least one cleat 30 is detachably fixed on the corresponding bridge tube 20. A protruding part 21 extending from one end of the bridge tube 20 far from the bridge tube 20 along the direction perpendicular to the axial line of the bridge tube 20 is formed at one end of the bridge tube 20 facing the caves 30, a first angle adjusting structure 51 is formed on the caves 30, a second angle adjusting structure 52 matched with the first angle adjusting structure 51 is formed on the bridge tube 20, a plurality of protruding parts are formed on one of the first angle adjusting structure 51 and the second angle adjusting structure 52, and a plurality of recessed parts are formed on the other one of the first angle adjusting structure 51 and the second angle adjusting structure 52. When the bridge tube 20 is combined with the cavel 30, the convex portion extends into the concave portion. The combination of the different convex portions and the concave portions enables the goat's horn 30 and the static parts on the bridge pipe 20, such as the connecting rod base, the damping spring support seat and the like, to have different relative angles, and after the convex portions and the concave portions are combined, the goat's horn 30 is prevented from rotating around the axis of the goat's horn 30 relative to the bridge pipe 20. The pressing plate 40 is located on one side of the protruding portion 21 far away from the cavel 30, a first connecting ring 31 is formed on one side of the cavel 30 facing the bridge tube 20, a second connecting ring 41 is formed on one side of the pressing plate 40 facing the cavel 30, threads are formed on the first connecting ring 31 and the second connecting ring 41, and the pressing plate 40 is fixed on the cavel 30 through screw threads so as to clamp the protruding portion 21 between the pressing plate 40 and the cavel 30. Preferably, threads are formed on the inner sidewall of the first connection ring 31 and the outer sidewall of the second connection ring 41, and the second connection ring 41 is inserted into the first connection ring 31 when the pressing plate 40 is fixed with the cavel 30.

In the present embodiment, the cleat 30 is detachably connected to the bridge tube 20 by separating the cleat 30 from the side bridge tube 20 on at least one bridge tube 20 and by using the pressing plate 40. When the caster angle of the kingpin needs to be adjusted, parts on one side of the vehicle can be disassembled. Further, the cavel 30 is rotated to a proper angle around the axis thereof, and the bridge tube 20 is combined with the cavel 30 again, so that the corresponding convex part extends into the corresponding concave part, and the combination position of the cavel 30 and the bridge tube 20 is changed; finally, the pressing plate 40 is screwed into the first connecting ring 31 of the goat's horn 30, so that the protruding portion 21 is clamped between the first connecting ring and the pressing plate 40, and the fixation of the goat's horn 30 and the bridge pipe 20 is completed.
