Description

Technical Field

[0001] The utility model relates to the technical field of drive assemblies, in particular to a positioning and installation structure of a travel drive assembly brake. Background Art

[0002] The travel drive assembly is the driving mechanism of the electric transport vehicle. It uses a brushless DC motor as the power and drives the transport vehicle through a secondary gear transmission. The driving gear and electromagnetic brake are installed on the output shaft of the brushless DC motor. When the transport vehicle is working, the electromagnetic brake is powered on first and the transport vehicle starts to run; when the transport vehicle stops at the designated position or the transport work is completed, the electromagnetic brake is powered off and braked. Therefore, the brake is an indispensable and important part of the travel drive assembly.

[0003] When the transport truck works for a long time or brakes frequently, the brake pads and electromagnetic coils of the electromagnetic brake will heat up, causing the braking effect of the electromagnetic brake to drop sharply, resulting in a longer braking distance of the transport truck, the inability to brake the car on the ramp, and even overheating causing the electromagnetic coil to burn out, causing the transport truck to be unable to operate normally. Based on this, in order to avoid the heat generated during work from affecting the operation and use of the brake, the brakes of the common travel drive assembly on the market are currently mainly installed on the reduction box cover by screws, which is a direct exposed installation. Then, when the travel drive assembly is loaded on the vehicle, the position where the brake is installed is more likely to collide with foreign objects on the ground. Although the direct exposed installation of the brake solves the problem of heat dissipation, the brake is also directly subjected to the impact from external foreign objects. The probability of damage to the brake caused by the impact is high, which poses a great challenge to the service life of the brake. Based on this, for the positioning and installation of the brake, how to avoid the heat generated during work from affecting the operation and use of the brake, and to resist the impact of external foreign objects on the service life of the brake to a certain extent, has become an urgent problem to be solved. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a positioning and installation structure of a travel drive assembly brake which has a simple structure, can realize stable positioning and installation of the brake, is beneficial to the heat dissipation of the brake and can provide certain protection for the brake.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A positioning and installation structure for a travel drive assembly brake comprises a reduction gear box cover, wherein the reduction gear box cover is provided with a brake installation area, wherein the brake installation area is provided with a through hole for a power supply shaft to pass through and install, and wherein the reduction gear box cover is provided with a plurality of positioning ribs around the brake installation area, wherein the plurality of positioning ribs are arranged at intervals and surround each other to form a positioning and installation cavity for the brake to be tightly fitted and embedded in and installed.

[0007] The positioning ribs are made of heat-conducting material.

[0008] The positioning rib is made of aluminum alloy material.

[0009] The positioning ribs include main positioning ribs, and two opposite side portions of the main positioning ribs are respectively protruded with auxiliary supporting ribs, so that the cross section of the positioning ribs is cross-shaped.

[0010] The outer end surface of the auxiliary support rib is an oblique end surface that tilts outward from top to bottom, so that the positioning rib forms a structure that is thin at the top and thick at the bottom.

[0011] The plurality of positioning ribs are asymmetrically arranged corresponding to the heat source positions of the brake.

[0012] The intervals between adjacent positioning ribs are all different.

[0013] The brake installation area has a brake installation plane and installation screw holes.

[0014] Compared with the prior art, the advantages of the utility model are: simple structure. First, a positioning installation cavity for the tight-fitting embedded installation of the brake is formed around the brake installation area by a plurality of spaced positioning ribs, which can realize the stable positioning installation of the brake on the reduction box cover and ensure that the brake can be installed coaxially with the motor shaft. The spacing between the plurality of positioning ribs does not affect the heat dissipation of the brake itself. Through the setting of the positioning ribs, large-area foreign objects from the outside will not directly hit the brake. The positioning ribs block these impacts, thereby achieving resistance to some external impacts to a certain extent, providing a certain protection for the brake, and extending the service life of the brake to a certain extent.

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] As shown in the figure, a positioning and installation structure of a travel drive assembly brake includes a reduction box cover 1, a brake installation area 10 is provided on the reduction box cover 1, a through hole 11 for the power supply shaft to pass through and install is provided in the brake installation area 10, and a plurality of positioning ribs 2 are provided on the reduction box cover 1 around the brake installation area 10, and the plurality of positioning ribs 2 are arranged at intervals and surrounded to form a positioning and installation cavity for the brake A to be tightly fitted and embedded for installation.

Arranging the positioning ribs 2 according to the heat source position of the brake A can speed up the heat dissipation at the heat source position, thereby helping the brake A to dissipate the heat generated during operation more quickly to ensure its stable operation.
