Description

Auxiliary supporting device for gearbox

Technical field

This utility model relates to a kind of support means, and the speed changing box support particularly to a kind of heavy vehicle fills Put.

Background technology

At present, in autocrane is arranged, change speed gear box utilizes a series of of circle distribution on bell housing Hole and flywheel shell of engine connect as one composition power assembly, and suspension arrangement is four-point supporting, have and send out Motivation location is reliable, the advantage of good stability, and its shortcoming is easily to produce location to interfere, to correlated parts The dimension precision requirement of design and processing is higher.Crane engine, the quality of change speed gear box and length are the most very Greatly, in order to avoid producing excessive moment of flexure on engine body rear end face and bell housing faying face, except starting Have on machine outside four-point supporting, also should increase an auxiliary on change speed gear box and support, generally, speed change Case auxiliary support apparatus is all that the connection being respectively symmetrically at the two ends of crossbeam has bracket assembly and bracket, is propping up Damping rubber block V-arrangement clamping plate are set between frame assembly and bracket.The amount of parts of this structure is more, Structure is complicated, and engineering machinery operating mode is severe, and power mounting vibration is relatively big, the unreasonable meeting of auxiliary support structure Crossbeam is caused to rupture, some row problems such as damping rubber block tear, affect vehicle driving safety, and make Cause high, reduce assembler's work efficiency, maintenance difficulty simultaneously.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of simple in construction, auxiliary support structure closes The auxiliary supporting device for gearbox of reason.

For solving above-mentioned technical problem, this utility model provides a kind of auxiliary supporting device for gearbox, extremely Including bearing, latch plate and two backing plates less, latch plate is arch, and latch plate two ends are respectively by two Backing plate is fixing with vehicle frame to be connected, the opening alignment change speed gear box of latch plate, the middle part of latch plate and the one of bearing End is fixing to be connected, and the other end of bearing is fixing with gear-box case to be connected.

After using such structure, suspension spring plate on vehicle frame is utilized to support the fixing, on the one hand of change speed gear box Latch plate itself can play the effect of damping bradyseism, and on the other hand mount supports system matches is without Planar Mechanisms, Make each part stress of this auxiliary supporting device for gearbox more uniform, it is to avoid stress is concentrated, solve power suspension The vibration impact to frame cross, plays downward position-limiting action to power assembly, and easy installation and reliable.

This auxiliary supporting device for gearbox can arrange position flexibly according to the space arrangement form of chassis system Put.

In order to be better understood from technology contents of the present utility model, below by this auxiliary supporting device for gearbox Referred to as this device.

It is provided with at least one cushion between bearing and the latch plate of this device；After using such structure, Cushion can play cushioning effect between bearing and latch plate, it is to avoid the two contacts firmly.

This device also includes base plate, and base plate is placed on downside in the middle part of latch plate, between base plate and latch plate It is placed with the first cushion；

Described bearing direction, upside in the middle part of latch plate is extended with connecting plate, and connecting plate has fixing hole, The second cushion also it is placed with between connecting plate and the latch plate of bearing；

Fixing bolt sequentially passes through in the middle part of the fixing hole of connecting plate, the second cushion, latch plate from top to bottom, First cushion and base plate.

After using such structure, make attachment structure between bearing and latch plate the most reasonable, further serve as To damping, the effect of bradyseism, and base plate is placed on the downside of latch plate and the first cushion and is possible to prevent to subtract Shake pad stress deformation.

The fixing hole of this device is mounting hole；After using such structure, can in use to bearing and The position of latch plate is finely adjusted, and facilitates routine use.

Detailed description of the invention

If Fig. 1 is to shown in 5

This support means includes bearing 3, latch plate 1, base plate 4 and two backing plates 2.

Latch plate 1 is arch, and two backing plates 2 are respectively welded at latch plate 1 two ends, latch plate 1 two ends Carrying on a shoulder pole in vehicle frame 8 both sides by backing plate 2, two backing plates 2 are then preset with on vehicle frame 8 respectively by bolt Two otic placodes 81 are fixed, the opening alignment change speed gear box 9 of latch plate 1.

Bearing 3 direction, upside in the middle part of latch plate 1 is extended with connecting plate 31, connecting plate 31 has fixing Hole 32, fixing hole 32 is mounting hole, and the length direction of fixing hole 32 hangs down with the length direction of latch plate 1 Directly, fix also by bolt between bearing 3 lower end and change speed gear box 9 shell.

Base plate 4 is placed on downside in the middle part of latch plate 1.

The first cushion 5, the connecting plate 31 of bearing 3 and spring it is placed with between base plate 4 and latch plate 1 The second cushion 6 also it is placed with between plate 1.

Fixing bolt 7 sequentially passes through fixing hole 32, second cushion 6 of connecting plate 31, bullet from top to bottom In the middle part of spring plank 1, the first cushion 5 and base plate 4.

Above-described is only a kind of embodiment of the present utility model, it is noted that for this area For those of ordinary skill, on the premise of without departing from this utility model principle, it is also possible to make some changes Type and improvement, these also should be regarded as belonging to protection domain of the present utility model.
