Description

Technical Field

[0002] At present, after the transmission with a retarder installed is assembled and tested, the retarder needs to be disassembled and inspected to verify the product status and failure mode. When disassembling the retarder at this stage, due to the small disassembly and assembly space and the lack of special disassembly and assembly tools, and due to the large product weight and volume of the transmission and retarder, especially the weight of the transmission is more than 200kg, it is necessary to use a hook to vertically hang the transmission and then disassemble and assemble the retarder each time. The process is time-consuming and laborious. Since the retarder has a certain inclination angle as a whole, the disassembled retarder is easy to tip over, which is very likely to cause safety accidents such as hand scratches and personal injuries, posing a great safety hazard.

[0033] In order to make the purpose, technical solutions and advantages of this application clearer, the following Figure 1-6 The present application is further described in detail. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0034] It should be understood that although the terms first, second, third, etc. may be used to describe in the embodiments of the present application, these descriptions should not be limited to these terms. These terms are only used to distinguish the descriptions. For example, without departing from the scope of the embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0035] First, in order to facilitate understanding of the retarder disassembly tool provided by the present application, the following explanation is made; the transmission and retarder of the present application have high product quality and are used in large vehicles, such as trucks or heavy trucks; the retarder is connected to the front end of the transmission by a circle of bolts, and the disassembly and assembly process requires workers to use tools for disassembly and assembly. Due to space limitations and product quality, the existing workshop uses a hoist to lift one end of the transmission so that the transmission is adjusted from the original horizontal state to a vertical state, and the retarder is prevented from tipping over by using a blocking block or manual methods. After the worker removes the circle of connecting bolts on the retarder, the transmission is lifted off the retarder. However, the defects are also obvious. During the disassembly process, due to the instability of the lifting rope, it is very easy for the worker to scratch his hands during the disassembly process, and after being lifted off the transmission, there is a lack of special equipment to prevent the retarder from tipping over, which can easily injure the worker, and the efficiency is very low, and the safety factor is low.

[0036] Based on the above content, the present application provides a retarder disassembly tool, including a bracket body 1, and the bracket body 1 includes: a detachably connected upper bracket 11 and a lower bracket 12; the upper bracket 11 and the lower bracket 12 form a accommodating chamber that can accommodate the retarder; the front end of the retarder extends out of the accommodating chamber and is connected to the transmission; the side walls and the front and rear sides of the top of the upper bracket 11 and the two side walls and the rear wall of the lower bracket 12 are all provided with a tightening structure 2 that can abut against the retarder.

[0037] Specifically, the retarder with the transmission is placed in the accommodating chamber by a crane, and the top, rear side and left and right sides of the retarder are clamped and fixed by the tightening structure 2 arranged on the side walls and front and rear sides of the top of the upper bracket 11 and the side walls and rear wall of the lower bracket 12. Then the operator removes the connecting bolts between the retarder and the transmission by a tool wrench. The disassembled bolts are not removed first, and the retarder is separated from the transmission by moving the bracket body 1 to complete the disassembly process of the retarder. Compared with the prior art, the disassembly and assembly process of the retarder has a high safety factor, high efficiency, and saves time and effort. Moreover, when installing the retarder, it is only necessary to move the bracket body 1, align the front end of the retarder with the transmission, and tighten it with bolts.

[0038] Optionally, the upper bracket 11 is a U-shaped structure, and the lower bracket 12 is an inverted U-shaped structure; the upper bracket 11 and the lower bracket 12 are buckled together to form an accommodating chamber; two first connecting plates 3 are provided on both sides of the bottom of the upper bracket 11, and correspondingly, second connecting plates 4 are provided at corresponding positions on both sides of the top of the lower bracket 12; the first connecting plate 3 and the second connecting plate 4 are fixed by bolts.

[0039] When in use, the transmission and retarder are lifted as a whole by a crane, and the retarder is placed inside the lower bracket 12, the upper bracket 11 is buckled on the upper part of the lower bracket 12, and the upper bracket 11 and the lower bracket 12 are connected and fixed by bolts; the advantage of this design is that it prevents the retarder from shaking during the disassembly and assembly process, thereby ensuring the overall stability of the retarder.

[0044] Optionally, the tightening structure 2 includes: a pushing screw 21, a clamping plate 22, and a connecting bearing; the pushing screw 21 is threadedly connected to the upper bracket 11 or the lower bracket 12, and the front end of the pushing screw 21 extends into the accommodating chamber and is connected to the clamping plate 22 through a connecting bearing; wherein a sinking groove for installing a connecting bearing is provided on the side wall of the clamping plate 22.

[0045] When in use, the screw rod 21 is screwed and pushed by a wrench to drive the clamping plate 22 to contact the end surface of the retarder, thereby stably fixing the retarder in the accommodating chamber to ensure the overall stability of the retarder.

[0046] Optionally, the clamping structure 2 also includes: a guide rod 23; the guide rod 23 is arranged parallel to the pushing screw 21; a limit stop block 24 is provided at one end of the guide rod 23, and the other end passes through a guide hole on the upper bracket 11 or the lower bracket 12 and is fixedly connected to the clamping plate 22; it can be understood that the design advantage of the guide rod 23 is to prevent the clamping plate 22 from rotating freely during the movement, and also ensure the stability of the movement of the clamping plate 22.

[0048] When in use, the pull rod 101 is pulled quickly to drive the spherical block 102 to collide with the impact plate 100, and the connection between the retarder and the transmission is separated by impact vibration, and then the bracket body 1 is pulled to move the retarder to the detection position.

[0049] Optionally, a protective plate made of hard plastic material that can contact the spherical block 102 is attached to the front end surface of the impact plate 100; the design advantage of the protective plate is to reduce the noise generated by the spherical block 102 and the impact plate 100, and secondly, prevent cracks from occurring at the connection between the impact plate 100 and the upper bracket 11 and the lower bracket 12.
