Description

Technical Field

[0001] This utility model belongs to the technical field of mining vehicles, specifically relating to a hoisting powertrain support device. Background Technology

[0002] Mining trucks belong to the category of off-highway dump trucks, specifically designed for mining and transportation. They are divided into two main types: traditional mining trucks and off-highway wide-body dump trucks. Used in open-pit coal mines and metal mines, they feature high-strength, wear-resistant steel bodies, heavy-duty traction diesel engines, and adaptability to extreme working conditions. Their load capacity reaches hundreds of tons.

[0003] Due to their heavy weight, long continuous working hours, and complex working environment, mining trucks are subject to continuous vibrations in their automatic transmissions, which can affect the service life of the automatic transmission mounts. Traditional mounts are achieved by beams installed between the chassis and the transmission, which is mounted on these beams. When the transmission rotates, centrifugal force causes the entire transmission to wobble, making the bolts connecting the transmission to the engine prone to breakage and tearing damage to the automatic transmission mounts. At the same time, the fatigue strength of the automatic transmission gradually increases under high-amplitude vibrations, resulting in poor shock absorption control during driving. This directly affects the performance of the power system, leading to a higher failure rate, reduced vehicle safety, and an increased risk of accidents. Utility Model Content

[0004] To address the shortcomings of existing technologies, a hoisting powertrain support device is provided to solve the problem of poor shock absorption in the powertrain of mining vehicles, which easily leads to the risk of breakage.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] like Figure 1-4 As shown, the present invention provides a hoisting powertrain support device, which is connected to the vehicle frame 3. That is, the powertrain is connected and fixed to the vehicle frame 3 through the support device. The hoisting powertrain support device includes: a first support component 1 and a second support component 2, wherein the power box can be an engine or a range extender, etc.

[0027] The first support assembly 1 is disposed at the junction of the power box and the transmission in the powertrain. The first support assembly 1 includes a first connecting portion 104 and a second connecting portion 105 arranged sequentially along the length direction of the frame 3. The first connecting portion 104 and the second connecting portion 105 are located on the same first support assembly 1. The first connecting portion 104 and the second connecting portion 105 are respectively used to connect with the power box and the transmission. The second support assembly 2 is disposed on the side of the first support assembly 1 away from the transmission. The two second support assemblies 2 are connected to the power box.

[0028] The first support component 1 is connected to the connection between the transmission and the power box in the powertrain. The two connection parts are connected to the power box and the transmission respectively, which improves the connection stability at the connection point, avoids the breakage of the connecting bolts between the transmission and the power box, and also reduces the possibility of cracks in the transmission housing, thus reducing the overall failure rate. Moreover, the second support component 2 is connected to the power box, which has a larger overall weight, so that the center of the powertrain is located between the first support component 1 and the second support component 2, and the two support components play a good supporting role.

[0029] Since the first connecting part 104 and the second connecting part 105 are located in the same support assembly, the connection stability between the power box and the gearbox can be guaranteed, and the situation of the connecting bolts between the power box and the gearbox being broken can be avoided.

[0030] To reduce the overall sway of the powertrain, two first support components 1 are provided, and the two first support components 1 are respectively connected to both sides of the powertrain; There are two second support components 2, and the two second support components 2 are respectively connected to both sides of the powertrain.

[0031] By setting two support components, which are located on both sides of the powertrain and connected to the side of the powertrain, the two support components can provide support from the side, avoiding the left and right swaying of the powertrain caused by the centrifugal force of rotation. Compared with the lifting connection method, it can better suppress vibration in the left and right direction.

[0032] Specifically, the first connecting part 104 and the second connecting part 105 in the first support assembly 1 are vertically arranged to form a side connection and fixation with the powertrain.

[0033] The first support component 1 includes: a first support frame 101, a first shock absorber 102, and a first connector 103.

[0034] One side of the first support frame 101 is connected to the vehicle frame 3, and the other side forms a support platform 106. Specifically, the top of the first support frame 101 is connected and fixed to the vehicle frame 3 by through bolts. The bottom of the first support frame 101 is bent toward the first connector 103 to form the support platform 106. A certain angle is formed between the support platform 106 and the first support frame 101. The support platform 106 is roughly horizontal. A reinforcing rib 108 is provided between the support platform 106 and the first support frame 101 to strengthen the connection between the first support frame 101 and the support platform 106 formed by the bottom bend. The support platform 106 and the first support frame 101 can be directly formed by integral bending or by welding.

[0035] The first shock absorber 102 is disposed on the support platform 106. The first shock absorber 102 is vertical, so that the shock absorption is in the vertical direction. A suspension platform 107 is disposed on one side of the first connector 103. The suspension platform 107 is connected to the first shock absorber 102, that is, the suspension platform 107 presses on the first shock absorber 102. The first connecting part 104 and the second connecting part 105 are disposed on the other side of the first connector 103. That is, the first connecting part 104 and the second connecting part 105 are located on the inner side of the first connector 103. The two connecting parts are connected to the engine and the transmission respectively by fasteners such as bolts. By placing the two connecting parts on the same first connector 103, the stress on the connecting bolts between the transmission and the engine is greatly reduced, avoiding the risk of bolt breakage between the transmission and the engine.

[0036] The connection stability with the gearbox is not provided. A reinforcing protrusion 109 is provided on the side of the first connector 103 away from the first support frame 101 on the second connection portion 105. The reinforcing protrusion 109 is located on the inner side of the first connector 103 near the gearbox. A connecting fastener 110 passes through the reinforcing protrusion 109. Specifically, the connecting fastener 110 passes through the reinforcing protrusion 109 and the first connector 103 to enhance the overall strength of the second connection portion 105.

[0037] Similarly, a number of fasteners 110 are provided on the first connecting part 104 for connecting with the engine. The fasteners 110 can be bolts.

[0038] Specifically, the reinforcing protrusion 109 includes a reinforcing frame 1091, and a connecting rib 1092 connecting the two sides of the reinforcing frame 1091 is provided in the middle of the reinforcing frame 1091. At least one connecting rib 1092 is provided. The connecting fastener 110 is provided at the corner of the reinforcing frame 1091 and at the junction of the reinforcing frame 1091 and the connecting rib 1092. The connecting fastener 110 is inserted at the corner of the reinforcing frame 1091 and at the intersection with the connecting rib 1092 because the position receives multi-directional restraint force, resulting in higher structural strength.

[0039] In this embodiment, the second support component 2 includes: a second support frame 201, a second shock absorber 202, and a second connector 203.

[0040] The second support frame 201 is connected to the vehicle frame 3 on the outside and can be fastened with bolts, etc. The inner side of the second support frame 201 can be connected to the support plate 205. The support plate 205 is provided with reinforcing plates 206 on both sides. The reinforcing plates 206 are connected to the inner side of the first support frame 101 to form a platform similar to the support platform 106. The second shock absorber 202 is provided on it. The second shock absorber 202 is vertically set on the support plate 205 on the inner side of the second support frame 201. One end of the second connector 203 is connected to the second shock absorber 202, and the other end is bent upward or downward to form a mounting surface 204 that contacts the side of the power box. The mounting surface 204 is vertically set, and bolts are formed on the mounting surface 204 to connect with the side of the engine. Four connection positions that contact the side of the engine are formed through the second connector 203 and the first mounting position on the first connector 103, which ensures the stability of the support for the heavy engine.

[0041] In this embodiment, the first shock absorber 102 includes two shock absorber pads 1021 and a connecting screw 1022.

[0042] The two shock-absorbing pads 1021 are sandwiched on both sides of the support platform 106 or the suspension platform 107. That is, the two shock-absorbing pads 1021 can be selectively arranged on the upper and lower surfaces of the support platform 106 or the upper and lower surfaces of the suspension platform 107. The connecting screw 1022 passes through the center of the two shock-absorbing pads 1021 and the suspension platform 107 and the support platform 106 and is then fixed.

[0043] Among them, the two shock-absorbing pads 1021 are respectively provided with outwardly protruding frustums 1023 on their opposite surfaces. Since the supporting platform 106 and the suspension platform 107 need to pass through the connecting bolts, through holes are opened on them. The outer edge of the frustum 1023 is matched with the through hole on the supporting platform 106 or the suspension platform 107, that is, the frustum 1023 is embedded in the through hole. The frustums 1023 on the two shock-absorbing pads 1021 are in contact with each other. The center of the frustum 1023 is used to pass through the connecting bolt 1022, which not only ensures the shock absorption effect of the shock-absorbing pads 1021, but also ensures the positioning connection between the shock-absorbing pads 1021 and the supporting platform 106 or the suspension platform 107.

[0044] The second shock absorber 202 has the same structure as the first shock absorber 102, and also includes two shock absorber pads 1021. The two shock absorber pads 1021 are sandwiched on both sides of the support plate 205 and are fastened at both ends after being inserted by connecting screws 1022.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
