Technical Field

The invention belongs to the technical field of automobile accessories, and particularly relates to a fracture-resistant universal joint fork of a high-quality commercial vehicle.

Background

The universal joint is a part for realizing variable angle power transmission, is used for changing the position of the transmission axis direction, and is a joint part of a universal transmission device of an automobile driving system. The universal joint is combined with a transmission shaft and is called a universal joint transmission device. On a vehicle driven by a rear wheel of a front engine, a universal joint transmission device is arranged between an output shaft of a transmission and an input shaft of a main speed reducer of a drive axle; the front engine front wheel driven vehicle omits a transmission shaft, a universal joint is arranged between a front axle half shaft which is in charge of driving and steering and wheels, and a common universal joint fork can crack or break after exceeding or overloading, so that the driving safety of the vehicle is influenced.

Application No.: CN201720208445.8 discloses an anti-fracture transmission shaft with a reinforced structure, which comprises a cover, a universal joint fork, a telescopic sleeve, an oil seal, a transmission shaft tube and a force-bearing steel tube, wherein an oil passage is arranged on one side of the telescopic sleeve, the telescopic sleeve fixes the oil passage by welding, a universal joint fork is fixedly arranged on one side of the oil passage, the universal joint fork is of an open structure, a cover is arranged on one side of the universal joint fork, a sliding spline shaft is arranged on the other side of the telescopic sleeve, a groove is chiseled on the outer side of the sliding spline shaft, the inner side of the telescopic sleeve is fixed by a sliding rail, the oil seal is welded on the other side of the sliding spline shaft, the oil seal is connected with an oil seal cover by a flange, a pipeline is arranged on one side of the oil seal cover, one side of the transmission shaft tube is welded by the pipeline, an anti-fracture support is arranged on the, the anti-fracture steel pipe is divided into four parts, namely an upper part, a lower part, a left part and a right part, and the anti-fracture steel pipe has good anti-fracture effect.

Based on the above, after the general universal joint yoke is exceeded or overloaded, the universal joint yoke cracks or breaks, which affects the driving safety of the automobile, so in order to reduce the breakage of the universal joint yoke, the strength of the universal joint yoke is improved to a certain extent.

Therefore, in view of the above, research and improvement are made on the existing structure and defects, and a high-quality commercial vehicle universal joint fork with fracture resistance is provided, so as to achieve the purpose of higher practical value.

Disclosure of Invention

In order to solve the technical problems, the invention provides a fracture-resistant universal joint yoke of a high-quality commercial vehicle, which aims to solve the problem that the universal joint yoke is cracked or fractured after exceeding or overloading and the driving safety of the vehicle is influenced, so that the strength of the universal joint yoke is increased by improving the universal joint yoke to a certain extent in order to reduce the fracture of the universal joint yoke.

The invention relates to a fracture-resistant universal joint yoke of a high-quality commercial vehicle, which is achieved by the following specific technical means:

A fracture-resistant universal joint fork for a high-quality commercial vehicle comprises a driving shaft, a fixing ring, a rolling ball, an inner driven ball, a driven shaft, a steel wire, a spacing layer and a fixing rib; the ball that the driving shaft is terminal is inside to be provided with interior driven ball, and still is provided with the fixed spin of fixed ring between inside and the interior driven ball of ball, inside driven ball and the mutual integrative design of driven shaft, and the outer terminal surface of driven shaft is provided with the steel wire, all be provided with the wall in the innermost and outside of steel wire, and be provided with fixed muscle between the spheroid of driving shaft and front end.

Furthermore, the driving block at the front end of the driving shaft is in a spherical shape, and a circular groove for the movement of the common rolling ball is formed in the sphere.

Furthermore, eight rolling balls for transmitting power between the driving shaft and the driven shaft are arranged, and each rolling ball is fixed through a fixing ring.

furthermore, an annular fixing rib is arranged between the sphere arranged at the tail end of the driving shaft and the driving shaft.

furthermore, the steel wires arranged on the outer wall of the driven shaft are four layers, and the steel wires which are not measured are fixed in a mutually staggered winding mode.

Further, the spacing layer is arranged at both the outermost surface of the steel wire and the inner surface of the innermost layer of the steel wire.

Compared with the prior art, the invention has the following beneficial effects:

The setting of transmission ball, the universal joint of mutual transmission improves into the spherical transmission universal joint that the bearing capacity is bigger between driving shaft and the driven shaft, and spherical transmission universal joint comprises spin and solid fixed ring and two transmission balls, and transmission power increases, and anti cracked effect has more been strengthened in spheroidal design.

The setting of steel wire is provided with the four layers of steel wire cover that the steel wire was twisted and is connect the formation in the outer wall of initiative futilely and driven lever, and the winding direction of the adjacent steel wire cover in layer is intercrossing shape, and the intercrossing design of steel wire cover more lets initiative and driven shaft can bear bigger load and anti cracked effect.

The interval layer sets up in the interior survey and the outside on the winding layer that the steel wire is constituteed with fixed muscle, and the interval layer can play protection steel wire and the inside initiative of steel wire and driven shaft effect, and the fixed muscle that driving shaft department set up prevents the fracture for the intensity increase that the driving shaft bore.
