The braking device of the traveling wheels of the prior art wheel loader is composed of an air pump (installed on the diesel engine), an air storage tank, a brake pedal, a brake valve, a booster pump, a brake air pipe, a brake oil pipe and a brake assembly. The air booster pump, also known as a booster, is a force-increasing device used for gas-liquid combined braking to convert input gas energy into output liquid energy. Since the existing front booster pump is arranged in the front frame and the rear booster pump is arranged next to the engine of the rear frame, the positions of the front and rear booster pumps are far away from the position of the foot valve. Due to the unreasonable arrangement of the front and rear booster pumps, a large air pressure loss will result, and the braking force of the wheel loader is relatively light, which may lead to a safety accident due to insufficient braking force.

DETAILED DESCRIPTION

[0024] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0025] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. In the absence of conflict, the embodiments and features in the embodiments of the present invention may be combined with each other.

[0026] The present embodiment provides a new type of booster pump mounting seat, including a booster pump cylinder fixing plate 1, a first connecting member 2, a horizontal bottom plate 3, a stiffening plate 4, a second connecting member 5 and a fixing seat 6. The booster pump cylinder fixing plate 1, the horizontal bottom plate 3 and the fixing seat 6 all adopt a rectangular structure. Two semicircular grooves 7 are symmetrically provided on the booster pump cylinder fixing plate. A plurality of bolt holes are provided around each semicircular groove 7 for fixing the left and right cylinders of the booster pump. In the present embodiment, the number of screw holes around each semicircular groove is three, and the three bolt holes form an isosceles triangle structure. The bolt hole at the highest point of the triangle is arranged adjacent to the highest point of the semicircular groove. Of course, the number of screw holes in the semicircular groove can be determined according to the booster pump installation requirements. It only needs to be able to stably fix the booster pump cylinder. The booster pump cylinder is fixed to the semicircular groove by bolts that cooperate with the bolt holes around the semicircular groove.

[0027] In this embodiment, there is a certain distance between the two semicircular grooves. The size of the distance is determined according to the size of the cylinders of the left and right booster pumps. It only needs to meet the normal use conditions of the booster pumps. The booster pump cylinder fixing plate is connected to one end of the horizontal base plate through a first connecting member, and the other end of the horizontal base plate is connected to the fixing seat through a second connecting member. The booster pump cylinder fixing plate and the fixing seat are staggered in the upper and lower positions, and the booster pump cylinder fixing plate and the fixing seat are both perpendicularly distributed at 90 degrees to the horizontal base plate.

[0028] There is a rectangular hollow structure between the horizontal bottom plate 3 and the fixing seat 6. The rectangular hollow structure can reduce the overall weight of the booster pump mounting seat in this embodiment.

[0029] Several bolt holes are arranged around the rectangular hollow structure of the fixing seat. In this embodiment, there are preferably four bolt holes arranged on the fixing seat, and each bolt hole is arranged near the four right-angled sides of the fixing seat. The four bolt holes arranged on the fixing seat will form a rectangular structure. The relevant installers can install the fixing seat at the corresponding mechanical structure of the loader according to actual installation requirements.

[0030] The first connecting member 2 and the second connecting member 5 have the same structure, both of which adopt an arc-shaped structure. Since the rectangular surfaces of the booster pump cylinder fixing plate 1 and the fixing seat 6 are staggered up and down, the arc-shaped surface 8 of the first connecting member 2 faces toward the booster pump, while the arc-shaped surface 8 of the second connecting member 5 faces away from the booster pump, which is exactly opposite to the direction of the first connecting member.

[0031] The stiffening plate 4 is located at the lower part of the horizontal bottom plate. In this embodiment, there are two stiffening plates, which are symmetrically distributed on the horizontal bottom plate 3. The shape of each stiffening plate is approximately triangular. The upper surface 9 of the stiffening plate is connected to the lower surface of the horizontal bottom plate 3, and the side 10 of the stiffening plate is connected to the side of the fixing seat 6 close to the horizontal bottom plate. Each stiffening rib can be provided with several weight-reducing holes according to actual requirements. Of course, weight-reducing holes can also be omitted. The stiffening ribs can enhance the stability of the booster pump mounting seat and increase the overall strength of the entire booster pump mounting seat.

[0032] The existing braking system is composed of an air pump (installed on a diesel engine), an air storage tank, a brake pedal, a brake valve, a booster pump, a brake air pipe, a brake oil pipe and a brake assembly. The compressed air generated by the air pump is input into the air storage tank. The brake pedal controls the brake valve. The brake valve and the booster pump are connected to the air storage tank in sequence using a brake air pipe. The other end of the booster pump is connected to the brake assembly using a brake oil pipe. The brake disc in the brake assembly is connected to the front and rear wheels. When the brake pedal is operated, the brake pedal controls the brake valve to be opened, and high-pressure gas enters the booster pump from the air storage tank through the brake valve. The oil pressure generated by the movement of the booster pump piston pushes the brake wheel cylinder in the brake assembly to move. The brake wheel cylinder drives the brake caliper to clamp the brake disc, and the wheel connected to the brake disc is braked. Since the existing front booster pump is arranged in the front frame and the rear booster pump is arranged next to the engine on the rear frame, the front and rear booster pumps are far away from the foot valve, which will cause a large air pressure loss, which will eventually cause soft braking, that is, weak braking force.

[0033] Based on the above situation, the staff can first arrange the boosting pump mounting base under the ladder on the left side of the wheel loader through the fixing base on the mounting base. After the boosting pump mounting base is completely fixed, the relevant staff can then fix the boosting pump cylinder on the corresponding semicircular groove through bolts to achieve a fixed connection between the boosting pump and the mounting base. At this time, the position of the boosting pump is very close to the foot valve (brake valve). When the brake pedal is operated, the brake pedal will control the conduction of the brake valve, and the high-pressure gas enters the boosting pump from the air tank through the brake valve. The high-pressure gas can quickly reach the boosting pump, reducing the loss of high-pressure air pressure during circulation. The high-pressure gas can push the boosting pump piston to move. Since the pressure lost during circulation is small, the oil pressure generated will push the brake cylinder in the brake assembly to move more, which can produce a greater braking effect, thereby solving the problem of soft brakes in the prior art.

[0034] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
