Abstract

The utility model relates to a universal gearbox suspension for a heavy truck, which comprises a mounting cross beam with two decurved ends, wherein, two ends of the mounting cross beam are respectively connected with support plates, two upper suspension movable brackets are uniformly distributed on the mounting cross beam, the lower part of each upper suspension movable bracket is connected with a thrusting rod, and the other end of the thrusting rod is connected with a lower bracket. When in use, the mounting cross beam is mounted on the longitudinal beam of a truck frame through the support plates at the two ends, and the lower ends of the two lower brackets are connected with the top of a gearbox. The universal gearbox suspension solves the problem that the traditional gearbox suspension structure can hardly restrain a power assembly from vibrating upwards, downwards, leftwards, rightwards and in the spinning direction, can achieve adjustability forwards, backwards, upwards and downwards, and is applicable to various arrangement positions of the power assembly. The universal gearbox suspension is in rigid connection with the longitudinal beam of the truck frame to effectively reduce the distortion of the truck frame. The installation of the thrusting rods at different angles ensures the upward and downward adjustment of the suspension, and rubber bushings can be used for reducing vibration.

Description

The general gearbox that is used for heavy duty truck suspends

Technical field

The utility model belongs to the heavy duty truck technical field, is specifically related to the gear box suspension system of heavy duty truck.

Background technology

The gear box suspension system of heavy duty truck is as the auxiliary support apparatus of dynamic assembly, be installed on the change speed gear box, guaranteeing that vehicle change speed gear box in operational process is out of shape does not under external force exceed allowed band, guarantees change speed gear box does not exceed allowed band under the limiting condition of vehicle displacement; Simultaneously suspension system also should have and suppresses vibration ability preferably, can reduce the moment of flexure that flywheel shell of engine bears.Is there the deficiency of which aspect in traditional gear box suspension? tradition gear box suspension beam connects to ground by rubber cushion, the easy torsional deflection of vehicle frame, and traditional in addition gear box suspension does not possess the universalization requirement.

Summary of the invention

For stability and the commonality that improves the gear box suspension system, reduce the layout needs of different automobile types driving engine diverse location simultaneously, the utility model provides a kind of general gearbox that is used for heavy duty truck to suspend.

The technical solution that realizes above-mentioned purpose is as follows:

The general gearbox that is used for heavy duty truck suspends and comprises a decurved installation crossbeam 1 in two ends, and the two ends that crossbeam 1 is installed are connecting stay bearing plate 2 respectively, and stay bearing plate 2 is the bent plate shape, offers slotted hole 7 on it; Install on the crossbeam 1 and be laid with the travel(l)ing rest 3 that suspends on two, the bottom of the travel(l)ing rest 3 that suspends on each is connecting propelling rod 5, and the other end of propelling rod 5 is connecting lower bracket 6.

Be laid with the travel(l)ing rest 3 that suspends on 8, two of two regulating tanks on the described installation crossbeam 1 and lay respectively in two regulating tanks 8, suspend on each travel(l)ing rest 3 in regulating tank movably distance L 1 be 0～100mm.

The cross-sectional plane of described stay bearing plate 2 is triangular in shape, and a side is connecting the end that crossbeam is installed, and offers slotted hole 7 on the described side.

The described junction that suspends travel(l)ing rest 3 and propelling rod 5 on each is provided with rubber bush 4, and the junction of propelling rod 5 and lower bracket 6 is provided with rubber bush.

Useful technique effect of the present utility model embodies in the following areas:

1, the utility model solved traditional gear box suspension structure be difficult to suppress dynamic assembly up and down with the vibration of torsional direction, gear box suspension can be realized front and back and controllability up and down simultaneously, can be general under the position of multiple dynamic assembly;

2, installation crossbeam of the present utility model and chassis side rail are rigidly connected, and can effectively reduce the torsional deflection of vehicle frame;

3, propelling rod during this suspends and rubber bush play a key effect to the vibration damping of dynamic assembly and the adjustment of position, and the different angles installation site of the propelling rod upper-lower position that guarantees to suspend can be adjusted, and rubber bush can play the effect of vibration damping.

4, rubber bush self parameter characteristic at this dynamic assembly design, guarantees each degree of freedom vibration vibration isolation efficiency of dynamic assembly for specially.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment:

Referring to Fig. 1 and Fig. 2, the general gearbox that is used for heavy duty truck suspends and comprises a decurved installation crossbeam 1 in two ends, the two ends that crossbeam 1 is installed are connecting stay bearing plate 2 respectively, stay bearing plate 2 is the bent plate shape, cross-sectional plane is triangular in shape, one side is connecting the end that crossbeam is installed, and offers slotted hole 7 on the described side.Install and uniformly on the crossbeam 1 to offer two regulating tanks 8, be separately installed with the travel(l)ing rest 3 that suspends in two regulating tanks 8, suspend on each bottom of travel(l)ing rest 3 is connecting propelling rod 5, the junction is equipped with rubber bush 4, the other end of propelling rod 5 is connecting lower bracket 6, and the junction is equipped with rubber bush.The travel(l)ing rest 3 that suspends on each can be adjusted mobile distance L 1 in regulating tank 8 be 0～100mm.

During use, referring to Fig. 1 the stay bearing plate 2 of crossbeam 1 by two ends is installed and is installed on the longeron of vehicle frame, the lower end of two lower brackets 6 is connecting the top of change speed gear box.Regulate the travel(l)ing rest 3 that suspends according to different vehicles and get final product, no longer need to change the structure of suspending mechanism in the position of installing on the crossbeam 1.Referring to Fig. 3, on suspend travel(l)ing rest 3 install on the crossbeam 1 by regulating tank 8 move L1 apart under the situation, change speed gear box can move up and down in the L2 distance range, rubber bush 4 can play the effect of vibration damping.

As shown in Figure 2, installation crossbeam 1 of the present utility model can realize that by the slotted hole on the stay bearing plate 27 front and back position changes.Installation crossbeam 1 of the present utility model is rigidly connected with vehicle frame, can effectively reduce the torsional deflection of vehicle frame.
