Abstract
The utility model relates to a gear box suspension device of a mine truck, and aims at providing a device capable of effectively reducing swaying times of a gear box of the mine truck, guaranteeing working properties of the gear box, and prolonging the service life of the gear box. The gear box suspension device of the mine truck is characterized by comprising two L-shaped supports, two motor front suspension cushions, a beam and a U-shaped bending plate. Each end portion of the beam is connected with one end of one motor front suspension cushion. The other end of each motor front suspension cushion is connected with one end of each L-shaped support. The other end of each L-shaped support is connected with the inner side of a mine truck frame. Two protruding ends of the U-shaped bending plate are connected with the middle portion of the beam, and the bottom end of the U-shaped bending plate is connected with the rear end of the gear box of the mine truck.
Description
Technical field
The utility model relates to a kind of suspending apparatus, particularly a kind of mine car speed changing box suspending device.
Background technology
Non-road mining car is used in open pit quarry, and it is mainly used in short-distance transport.The common load of this mine car is large, in road conditions, on poor road surface, exercise, its gear box suspension belonged to location on vehicle frame, but due to change speed gear box with odd-side and far away apart from Motor Mass Centre, very large on the engine bracket of sandwich mounting impact, when driving engine rocks, change speed gear box is caused to the force of inertia distance, if things go on like this, affect work and the service life of change speed gear box normal reliable.
The utility model content
For deficiency of the prior art, the utility model aims to provide and a kind ofly can effectively reduce the device that the mine car change speed gear box rocks, and guarantees the serviceability of change speed gear box, improves its service life.
In order to address the above problem, this kind of mine car speed changing box suspending device is characterized in that comprising: two L brackets, two engine front mounting cushions, crossbeam and U-shaped bent plates; Each end of crossbeam all is connected with an end of an engine front mounting cushion, and the other end of engine front mounting cushion is connected with an end of L bracket, and the other end of L bracket is connected with the mine car frame inside; Two jags of U-shaped bent plate are connected with the middle part of crossbeam, and bottom is connected with the rear end of mine car change speed gear box.
Preferably, be provided with the first backing plate between the rear end of the bottom of described U-shaped bent plate and mine car change speed gear box; Described engine front mounting cushion and L bracket are bolted, and are provided with the second backing plate between bolt and L bracket.
Preferably, two of described U-shaped bent plate jags and crossbeam is bolted and by two standby fastening nuts.
Preferably, the shore hardness of described engine front mounting cushion is 60HA-70HA.
More preferably, described L shape support is provided with reinforced rib, and the steel plate that described crossbeam is Q235A by model is made.
The beneficial effects of the utility model are: by adopting this kind of structure, the cushion in this structure can stretch, and compression stiffness is large, at vertical direction, very large elasticity is arranged, and this cushion and engine front bracket and crossbeam are rigidly connected and can slow down change speed gear box and teetertotter.The force of inertia distance that gearbox device energy actv. of the present utility model subduction has driving engine to rock to cause, thus the work of change speed gear box normal reliable guaranteed, improved its service life.
The accompanying drawing explanation
Fig. 1 is mine car speed changing box suspending device structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of mine car speed changing box suspending device of the present utility model, it comprises: two L brackets 2, two engine front mounting cushions 6, crossbeam 3 and a U-shaped bent plate 4.Crossbeam 3 adopts the steel plate bending that model is Q235A, and thickness is 8mm, and its contour dimension is long 820mm, wide 121mm, high 35mm.
This crossbeam each end all with an end of an engine front mounting cushion 6, be connected, and the other end of engine front mounting cushion 6 is connected with an end of L bracket 2.Concrete, after screw bolt passes second backing plate 7, L bracket, engine front mounting cushion 6 and crossbeam 3, end is fixed with nut.The other end of L bracket 2 and mine car frame inside are bolted.This L bracket adopts the foundry goods form, has improved greatly reliability, and its contour dimension is long is 173mm, and wide is 180mm, and height is 130mm, and its middle part is provided with reinforced rib 21.U-shaped bent plate 4 adopts the general steel plate bending, and material is Q235A, and thickness is 8mm, and its contour dimension is long 330mm, wide 105mm, high 50mm.Its cross section roughly takes the shape of the letter U, and has two jags and the bottom that is connected two jags.The middle part of two jag and crossbeam 3 is bolted, and the end of this bolt is by two standby fastening nuts.The bottom of U-shaped bent plate 4 is connected by thru-bolt with the rear end of mine car change speed gear box 1.
Preferably, be provided with the first backing plate 5 between the rear end of the bottom of described U-shaped bent plate 4 and mine car change speed gear box 1, guarantee the rigidity that is connected between change speed gear box and U-shaped bent plate, prevent that the bottom of U-shaped bent plate is because long stressed generation is ruptured.In addition, the shore hardness of described engine front mounting cushion 6 is 60HA-70HA.
Described engine front mounting cushion is existing cushion, and it adopts double-deck sandwich construction, this construction stretch, and compression stiffness is large, at vertical direction, very large elasticity is arranged, and this cushion and engine front bracket and crossbeam are rigidly connected and can slow down change speed gear box and teetertotter.The force of inertia distance that gearbox device energy actv. of the present utility model subduction has driving engine to rock to cause, thus the work of change speed gear box normal reliable guaranteed.
